A long-standing question in the study of quantity discrimination is what stimulus properties are controlling choice. While some species have been found to do it based on the total amount of stimuli and without using numerical information, others prefer numeric rather than any continuous magnitude. Here, we tested cats, dogs, and humans using a simple two-way spontaneous choice paradigm (involving food for the first two, images for the latter) to see whether numerosity or total surface area has a greater influence on their decision. We found that cats showed preference for the larger amount of food when the ratio between the stimuli was 0.5, but not when it was 0.67; dogs did not differentiate between stimuli presenting the two options (smaller vs. larger amount of food) regardless of the ratio between them, but humans did so almost perfectly. When faced with two stimuli of the same area but different shapes, dogs and humans exhibited a preference for certain shapes, particularly the circle, while cats’ choices seemed to be at chance level. Furthermore, cats’ and dogs’ reaction times were equal across conditions, while humans were quicker when choosing between stimuli in trials where the shape was the same, but the surface area was different, and even more so when asked to choose between two differently sized circle shapes. Results suggest that there is no universal rule regarding how to process quantity, but rather that quantity estimation seems to be tied to the ecological context of each species. Future work should focus on testing quantity estimation in different contexts and different sources of motivation.First post-contrAst SubtracTed (FAST) MRI, an abbreviated breast MRI scan, has high sensitivity for sub-centimetre aggressive breast cancer and short acquisition and interpretation times. These attributes promise effective supplemental screening. Until now, FAST MRI research has focused on women above population-risk of breast cancer (high mammographic density or personal history). DYAMOND aims to define the population within the population-risk NHS Breast Screening Programme (NHSBSP) likely to benefit from FAST MRI. The study population is the 40% of screening clients aged 50–52 who have average mammographic density (BI-RADS (Breast Imaging Reporting and Data System) B) on their first screening mammogram. DYAMOND will answer whether sufficient numbers of breast cancers, missed by mammography, can be detected by FAST MRI to justify the inclusion of this group in a future randomised controlled trial.
Prospective, multicentre, diagnostic yield, single-arm study with an embedded qualitative sub-study: all recruited participants undergo a FAST MRI. An internal pilot will assess the willingness of sites and screening clients to participate in the study. Screening clients aged 50–52, with a clear first NHSBSP mammogram and BI-RADS B mammographic density (by automated measurement) will be invited to participate (recruitment target: 1000). The primary outcome is the number of additional cancers detected by FAST MRI (missed by screening mammography). A Fleming’s two-stage design will be used as this allows for early stopping after stage 1, to save participants, funding costs and time continuing to the end of the study if the question can be answered earlier.
The NHSBSP Research and Innovation Development Advisory Committee and the Yorkshire and Humber–Sheffield Research Ethics Committee (23/YH/0268, study ID (IRAS): 330059) approved this research protocol. Participation involves a two-stage informed consent process, enabling screening for eligibility through automated mammographic density measurement. Patients with breast cancer helped shape the study design and co-produced participant-facing documents. They will disseminate the results to the public in a clear and meaningful way. Results will be published with open access in international peer-reviewed scientific journals.
Radiological imaging is a central facet of the multidisciplinary evaluation of suspected child physical abuse. Current guidelines for the imaging of suspected child physical abuse are often unclear, incomplete and highly variable regarding recommendations on critical questions, thereby risking clinical heterogeneity, unstructured decision-making and missed diagnoses. We, therefore, aim to develop and report an evidence-based and consensus-derived international guideline for the radiological investigation of index and contact children in the context of suspected physical abuse and to ascertain areas of scientific uncertainty to inform future research priorities.
The international guidelines for the imaging investigation of suspected child physical abuse (IGISPA) consensus group includes formal representation from 127 recognised experts across 14 subspecialties, six continents and 32 national and/or international organisations. Participants will be divided into five longitudinal subgroups (indications for imaging, skeletal imaging, visceral imaging, neuroimaging and postmortem imaging) with three cross-cutting themes (radiography, genetics and adaptations for low- and lower-middle-income countries). Each subgroup will develop preliminary consensus statements via integration of current evidence-based guidelines, systematic literature review and the clinical expertise of a multinational group of experts. Statements will then undergo anonymised voting in a modified e-Delphi process and iterative revision until consensus (≥80% agreement) is achieved. Final statements will undergo both internal and external peer review prior to endorsement.
As an anonymous survey of consenting healthcare professionals, this study did not require ethical approval. Experts provided written informed consent to participate prior to commencement of the modified Delphi process. The IGISPA consensus statement and any subsequent guidance will be published open access in peer-reviewed medical journals.
The only supportive therapy for patients with severe acute kidney injury (AKI), a common complication among the critically ill, is dialysis. Based on the literature and current guidelines, continuous renal replacement therapy (CRRT) with a total effluent dose of 20–25 mL/kg/hour and adjustments to ensure such dose is delivered despite down time (eg, due to surgical procedures) is recommended. However, experimental and clinical studies suggest that azotaemia, which can be induced by lowering the effluent dose, may accelerate renal recovery. This clinical study investigates whether a lower effluent dose (10–15 mL/kg/hour) for a maximum of 7 days or until successful (>24 hours) liberation of CRRT in critically ill patients with a dialysis-dependent AKI accelerates renal recovery and reduces time on CRRT compared with guideline-directed standard dose (25–30 mL/kg/hour).
The Ketzerei trial is an international, multicentre randomised, controlled trial, designed to investigate if a lower effluent dose (10–15 mL/kg/hour) accelerates renal recovery and reduces the time on CRRT compared with the guideline directed standard effluent dose (25–30 mL/kg/hour). The study aims to enrol 150 critically ill patients with a dialysis-dependent AKI. Eligible patients will be randomised to receive either a standard effluent dose (control group, 25–30 mL/kg/hour) or lower effluent dose (interventional group, 10–15 mL/kg/hour). The primary endpoint is the number of days free from CRRT and alive (from randomisation through day 28). Key secondary endpoints include the number of (serious) adverse events due to potential uremia, the duration of RRT and intensive care unit survival.
The Ketzerei trial has been approved by the Ethics Committee of the Chamber of Physicians Westfalen-Lippe (2023–343 f-s), the University of Muenster and subsequently by the corresponding Ethics Committee of the participating sites. Results will be disseminated widely and published in peer-reviewed journals, presented at conferences and will guide patient care and further research.

This study examined the patterns and persistence of SARS-CoV-2 seropositivity among college students from March to November 2020. Using data from a sample of students at Indiana University, we assessed (1) the duration and seropositivity following reverse transcription-PCR (RT-PCR)-confirmed SARS-CoV-2 infection and (2) persistence of seropositivity over 10 weeks between two laboratory antibody test visits.
The longitudinal study was conducted at Indiana University from September to November 2020, with two laboratory antibody tests, and included self-reported RT-PCR results before the observational period from as early as 20 March 2020. This 6–9 month period contributes to our understanding of seropositivity dynamics. The study included 172 college students who had previously tested positive for SARS-CoV-2 and measured their seropositivity.
Our results showed a notable decline (66.7%) in antibody positivity over the observed period. Additionally, 12 weeks postinfection, most students with a SARS-CoV-2 infection history (75%) were no longer seropositive.
These findings reveal a nuanced picture of antibody dynamics, highlighting the complex interplay of factors among college students. The study underscores the need for continued research on antibody levels among young adults to better understand the drivers of variations in antibody persistence.
The COVID-19 pandemic has made long-standing nursing workforce challenges apparent on an international scale. Decision-makers must develop multi-pronged approaches to foster the development and maintenance of a strong nursing workforce to support health systems. These approaches require attendance to recruitment and retention initiatives that show promise for stabilising the nursing workforce now and into the future.
Searches were conducted across MEDLINE, Embase, CINAHL and Scopus from January 2014 up to 11 March 2024. This rapid umbrella review protocol is guided by the Joanna Briggs Institute scoping review methodology and adheres to Preferred Reporting Items for Systematic Review and Meta-Analysis Protocols guidelines. The research question guiding this review is: what structures have healthcare systems put in place to stabilise, support and sustain the nursing workforce? This review will include existing reviews of nursing workforce initiatives with outcomes that impact nursing recruitment and retention. Results will support local health transformation including the development of a jurisdictional nursing workforce stabilisation strategy. Findings from this review will be relevant for the design, refinement and implementation of nursing workforce sustainability strategies in countries around the globe and may apply to strategies for other healthcare workers.
Institutional research ethics board exemption was received. The research team is supported by an advisory group that includes provider and patient partners. The results from this study will inform the Nursing Workforce Strategy for the province of Nova Scotia as part of a larger Canadian Institutes of Health Research-funded project. They will also inform broader planning and strategy in Canada through integration with other evidence-generation activities such as comparative policy analyses and workforce planning exercises. Finally, the results will be published in a peer-reviewed journal.

Blue light (peak wavelength 442 nm) has been shown to modulate the immune response in preclinical models of intra-abdominal sepsis and pneumonia. In vivo pathways involve optic nerve stimulation with transmission to the central nervous system, activation of parasympathetic pathways terminating at the spleen, and downstream immune effects including decreased inflammatory tissue damage and improved pathogen clearance. Related effects on pain mediators including proinflammatory cytokines (interleukin 6, TNF- α) and autonomic tone (increased parasympathetic outflow) suggest possible analgesic properties that would be highly relevant to a trauma population.
This is a randomised controlled trial in which adult trauma inpatients (
Full ethical approval for this trial has been granted by the University of Pittsburgh Institutional Review Board. On study completion, results will be published in the peer-reviewed literature and at ClinicalTrials.gov.
Continuous glucose monitoring (CGM) provides real-time glucose data for people with diabetes. However, detailed knowledge of its use in daily life remains limited. We aim to investigate the interaction between people with type 1 diabetes (T1D) and their CGM data and the impact of the interaction on glycaemia and diabetes distress.
This is a two-centre observational study of adults (n=500) with T1D using FreeStyle Libre 2. Over a period of 14 days, participants will continue their regular CGM use, record insulin doses and timing with smart insulin pens, track activity and sleep with an activity tracker, log all food intake in the LibreLink app and answer questions about quality of life and hypoglycaemia two times per day. Before the study period, the participants will complete a survey of 11 validated questionnaires assessing diabetes distress, hypoglycaemia awareness and other patient-reported outcomes (PROs). After the study period, the participants will complete two additional questionnaires assessing diabetes distress and health literacy.
The collected data will be used in two substudies with the overall aims of:
Substudy 1: to investigate how CGM is used in practice and the impact of the interaction on diabetes distress and glycaemia.
Substudy 2: to investigate whether and how CGM functions as a technological substitute for impaired awareness of hypoglycaemia, focusing on alarm data.
Endpoints will include CGM metrics, alarm data and PROs.
The Danish Data Protection Agency approved the study (P-2024–15985), and the regional committee on health research ethics has granted an ethical waiver (H-24014662). All participants have signed written informed consent forms before participating. The results will be published in an international peer-reviewed scientific journal by the study investigators and shared via www.clinicaltrials.gov. Participants who agreed to receive information about the study will be sent the results after publication.

To explore mental health help-seeking behaviours among East Asian American dementia caregivers and construct a theory grounded in their behaviour patterns.
Qualitative using constructivist grounded theory design.
We recruited 20 East Asian American dementia caregivers between August 2023 and March 2024 using purposive sampling. We conducted one-on-one interviews and analysed the data using constructivist grounded theory coding.
We constructed a theory including six concepts and 22 categories. While ‘providing care’, caregivers manage caregiving tasks and personal life, experiencing caregiving challenges. ‘Individual capacity’ is a key to perceiving caregiving situations and ‘considering seeking support’. Various factors can affect ‘using support’. Different types of support can be used separately or in combination. When receiving adequate support, caregivers can ‘gain benefits from support’. These benefits, alongside individual capacities, can shape caregivers' ‘outlook on the present and the future’.
This study explains the mental health help-seeking process within East Asian culture, broadening perspectives on diverse populations and highlighting insights into culturally tailored services.
This study offers clinicians and communities insights into the mental health help-seeking process among East Asian American dementia caregivers and highlights strategies to encourage their use of mental health services.
This theory incorporates aspects of East Asian culture, addressing a research gap in studies of Asian Americans. It may enhance understanding of culturally tailored approaches and facilitate future funding for research and services, considering cultural diversity.

BackgroundCOVID-19 vaccination is crucial for pregnant women to protect against severe complications during pregnancy. However, vaccine hesitancy and refusal can affect acceptance rates among this vulnerable group, posing risks to both maternal and fetal health. This research was conducted to explore the barriers and facilitators influencing COVID-19 vaccination among Malaysian pregnant women.
MethodsThis qualitative study adopted a hermeneutic phenomenological design. Nineteen pregnant women receiving antenatal care at three clinics in Kelantan between February 2024 and June 2024 were purposively selected to participate in in-depth interviews. The interviews were audio-recorded, transcribed verbatim, and analyzed using NVivo software alongside manual coding. Thematic analysis, incorporating both inductive and deductive approaches, was conducted to identify key themes.
ResultsMost pregnant women expressed hesitancy toward COVID-19 vaccination during pregnancy due to various concerns. Our findings identified four key themes as barriers to vaccination: (i) Fear of side effects, (ii) Negative social influences, (iii) Perception of returning to normalcy, and (iv) Vaccine scepticism and prejudice. Conversely, three themes emerged as facilitators of vaccine acceptance: (i) Concerns about the effects of COVID-19 infection, (ii) Trust in the vaccine, and (iii) Personal and shared vaccination experiences.
ConclusionThis study identified key factors influencing COVID-19 vaccine hesitancy. These findings highlight the importance of addressing both personal and social dimensions of vaccine hesitancy. Public health interventions should focus on building trust, countering misinformation, and leveraging positive community experiences to encourage vaccine uptake, particularly in populations where hesitancy remains a concern.
To extract and interpret quantitative data exploring the effectiveness of family health conversations (FHCs) on family functioning, perceived support, health-related quality of life, caregiver burden and family health in families living with critical or chronic health conditions.
Addressing the health of families affected by critical or chronic illnesses requires focused attention. The effective integration of FHCs is hampered by a scarcity of rigorous quantitative studies that provide solid evidence on best practices and outcomes.
A systematic review following the Joanna Briggs Institute guidelines.
The review is reported according to the PRISMA 2020 checklist. Appropriate studies were searched in PubMed, CINAHL, PsycINFO, Scopus and Cochrane Databases. Results of the search were imported into the Covidence web-based program. Included were studies with a quantitative research design, delivered to families with critical or chronic health conditions, describing FHCs based on the Calgary Family Assessment Model and/or the Calgary Family Intervention Model, and/or the Illness Beliefs Model, using reliable and validated instruments, published between 2008 and 2023, and written in English.
In total, 24 papers met the inclusion criteria. Sixteen papers used a quasi-experimental design, eight of which included a control group. Two papers used a mixed methods design, and six papers were randomised controlled trials (RCTs). A statistically significant effect of FHCs on family functioning was reported in two RCTs and three quasi-experimental papers. We also found that a statistically significant effect of FHCs was reported on perceived support in 9 of 15 papers, quality of life in 4 of 11 papers and caregiver burden in 1 of 3 papers.
The interventions reviewed revealed variability and partial results concerning the effectiveness of FHCs on family functioning. More rigorous research about short-term, intermediate- and long-term effectiveness is needed before conclusions can be drawn.
The study is reported according to the PRISMA 2020 (Preferred Reporting Items for Systematic reviews and Meta-Analyses) (File S1).

To identify implementation strategies that effectively facilitate the adoption of social needs care coordination activities using enabling technologies among care management teams serving patients in community-based health centres.
Modified Delphi process.
Discrete, feasible implementation strategies were identified through literature review and semi-structured interviews with care management staff and subject matter experts in clinical informatics, workflow redesign, and product engineering. A modified Delphi was conducted with eight subject matter experts and nine health centre care management staff. Iterative rounds of online surveys were used to achieve consensus on the most relevant implementation strategies and their delivery methods.
The modified Delphi process achieved consensus on nine discrete implementation strategies needed to advance care management teams' ability to screen, refer and track social needs. Prioritised strategies included developing champions, enhancing quality improvement capacity, training staff on using enabling technologies and providing tailored technical assistance for workflow refinement. Consensus was also reached on a monthly cadence for most of the implementation strategies.
Consensus was reached on strategies to enhance care management teams' implementation of social needs screening, referrals and tracking using enabling technologies. These strategies will comprise an intervention to be pilot tested, refined and assessed in a cluster randomised clinical trial.
Findings from this study will inform the development of strategies to further the adoption of enabling technologies to support social needs care coordination.
This work is key to the design of a type 2 hybrid implementation-effectiveness trial that will assess whether user-informed, evidence-based implementation strategies can improve care management teams' adoption of enabling technologies to facilitate social needs care coordination for patients.
The research team includes a patient advisor with community-based nursing expertise and a nurse practitioner-clinical informaticist leader who was involved in data collection and interpretation of findings.
Trial registration: Clinicaltrials.gov registration # NCT06489002. Registered July 5, 2024, https://clinicaltrials.gov/study/NCT06489002?term=NCT06489002&rank=1.
Sleep is a biological necessity with vital effects on all tissues and organs of the body. Preoperative sleep disturbance is associated with increased postoperative pain intensity and opioid consumption. Given that insomnia is a potentially modifiable risk factor, interventions targeting sleep prior to surgery may improve postoperative pain control and enhance key outcomes of recovery.
Promoting Sleep to Alleviate Pain-Arthroplasty (PROSAP-A) is a randomised, parallel group, two arm, controlled trial evaluating the effects of preoperative sleep-promotion on postoperative pain control, brain health and physical recovery. The main objective is to investigate whether preoperative insomnia treatment in patients scheduled to undergo total knee arthroplasty (TKA) or total hip arthroplasty (THA) may improve acute postoperative pain control. 100 adults with insomnia disorder (Insomnia Severity Index score >10 and confirmed Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition criteria for persistent insomnia disorder), scheduled to undergo primary TKA or THA, will be randomised to preoperative cognitive behavioural therapy for insomnia (CBT-I) or an active comparator control intervention, sleep education therapy (SET). Both interventions will be delivered over 4 weeks in hybrid format through a digital self-guided platform in combination with weekly telehealth video sessions with a psychologist (CBT-I) or research nurse (SET). A video-assisted booster session will be provided 1–2 weeks postoperatively. The primary outcome measure is acute postoperative pain intensity, averaged over the first 7 postoperative days (POD). Secondary outcome measures include long-term postoperative pain control, changes in quantitative sensory testing variables (eg, temporal summation, conditioned pain modulation), sleep, cognition (eg, attention, memory, processing speed, executive function), mental health, health-related function, physical activity, quality of life and blood biomarkers. Participants will undergo on-site evaluation preoperative (preintervention and postintervention) and 6 months postoperative. Additional remote assessments will take place during POD1–7, 3 and 12 months postoperative.
The Swedish Ethical Review Authority has approved the PROSAP-A trial protocol. Results will be published in international peer-reviewed journals and summaries will be provided to funders and participants of the trial.
Elder neglect by both informal and formal caregivers is common, particularly among persons with dementia, and has serious health consequences but is under-recognised and under-reported. Persons with dementia are often unable to report neglect due to memory and language impairments, increasing their vulnerability. Screening for elder mistreatment and initiation of intervention in primary care clinics may be helpful, but few evidence-based tools or strategies exist. We plan to: (1) develop a novel primary care screening tool to identify elder neglect in persons with dementia, (2) develop an innovative technology-driven intervention for caregivers and (3) pilot both for feasibility and acceptability in primary care.
We will use a multistep process to develop a screening tool, including a modified Delphi approach with experts, and multivariable analysis comparing confirmed cases of neglect in patients with dementia from the existing data registry to non-neglected controls. We will develop an evidence-based, technology-driven caregiving intervention for neglect with an expert panel and iterative beta testing. Following the development of the protocol for implementation of the tool and intervention with associated training, we will pilot test both the tool and intervention in older adult patients and caregivers. We will conduct provider focus groups and interviews with patients and caregivers to assess usability and will modify the tool and intervention. These studies are in preparation for a future randomised trial.
Initial phases of this project have been reviewed and approved by the Weill Cornell Medicine Institutional Review Board, protocol #22-06024967, with initial approval on 1 July 2022. We aim to disseminate our results in peer-reviewed journals, at national and international conferences and among interested patient groups and the public.
The needs of patients in palliative care (PC) are multiple and changing. Several tools assess them, but there is a lack of homogeneity among them. A specific diagnostic tool to assess complexity in PC (IDC-Pal: Instrumento Diagnóstico de la Complejidad en Cuidados Paliativos, in Spanish) was created in community and hospital settings with 36 items to diagnose PC complexity, but its application in primary care is difficult.
(1) To generate an adapted version to primary care of the IDC-Pal tool to identify and stratify PC complexity in the adult population. (2) To determine face, content, criterion and construct validity and reliability of the new instrument.
There are three phases of clinimetric cross-sectional observational validation study: Phase 0: Review of the original tool structure suitability for its use in primary care setting by a committee (researchers and the original developer team). Phase 1: Expert consensus phase by Delphi technique with physicians, nurses and social workers from primary care and PC. Phase 2: Empirical validation of the resulting tool in primary care using a cross-sectional descriptive design involving physicians and case manager nurses from across Andalucia, who will recruit adult patients with PC needs from healthcare centres that accept to participate in the study. Reliability (Cronbach’s alpha, McDonald’s omega, interclass correlation coefficient) and construct validity (exploratory factor analysis) analysis will be carried out; convergent criterion validity will be assessed with the NEC-PAL (Necesidades Paliativas Questionnaire, in Spanish) instrument. Differences by gender, type of professional and place where it is administered will be explored. Interobserver reliability analyses will be carried out using intraclass correlation coefficient, Bland-Altman plots and concordance analysis. Phase 0–1 results were expected by 2025 and Phase 2 results by 2026. Reporting method: CRISP checklist. This protocol was conducted without patient or public participation.
This study evaluates a novel, co-designed tool to diagnose PC complexity to inform practice recommendations for a more efficient allocation of resources that may be included in future clinical practice guidelines. The study has been approved by the Provincial Research Ethics Committee of Málaga as of July 2023 and will be conducted in accordance with the principles established in the Declaration of Helsinki, the Council of Europe Convention on Human Rights and Biomedicine, and the requirements established in Spanish legislation. The study conforms to the norms of good clinical practice. All participants in the Delphi study must express their agreement to participate in the survey by providing informed consent (IC) before beginning the questionnaire. For the development of Phase 2, the primary care professionals who agree to participate will sign a researcher commitment, and the patients included in the study will sign a written IC before the data collection. Dissemination of the results will inform future research on the appropriate diagnosis of PC complexity in the primary care setting, which is of paramount importance due to its gatekeeper position. Dissemination will be aimed at academics and healthcare professionals through publications, presentations and training workshops on the use of the diagnostic tool.
An increasing number of teenagers and young adults (TYA) with chronic conditions and complex needs are transitioning from paediatric to adult services, including admission to intensive care units (ICUs). As these services are often ill-equipped to care for TYA, there is a risk of compromised care. Despite recent guidelines from the UK Paediatric Critical Care and Intensive Care Societies highlighting the importance and urgency of improving ICU transition, current recommendations are not evidence-based and established pathways for ICU transition remain limited.
This mixed-methods research study aims to generate evidence to underpin national policy on transition from paediatric to adult ICUs that will improve clinical care and patient experience. To do this, we will: (1) link and analyse UK national data (years 2017–2024) on paediatric and adult ICU admissions, hospital inpatient, outpatient and emergency care visits and survival status, to determine the clinical characteristics and healthcare resource utilisation from teenage years to early adulthood of people admitted to an ICU as a young person (admission aged 14 and 15), and how these relate to ICU admissions after age 16; (2) conduct semistructured interviews, online forums and surveys with TYA patients, carers and health professionals to understand their experience of transition in ICU services; and (3) synthesise these strands of evidence and use a structured process of stakeholder engagement to propose potential targeted improvements as appropriate.
This study was approved by the East of England - Cambridge South Research Ethics Committee on 1 August 2024 (research ethics committee number 24/EE/0108), and the Health Research Authority Confidentiality Advisory Group (CAG) on 7 October 2024 (CAG number 24/CAG/0068). Study results will be actively disseminated through peer-reviewed journals, conference presentations and accessible lay texts and graphic summaries for the use of charities and patients including those with learning disabilities and neurodevelopmental disorders.
Social norms are often implicit informal rules that most people accept and abide by, and can influence how people behave, sometimes based on perceived rewards and/or sanctions. Social norms are propelled by some reference or population groups who exert a considerable amount of influence on behaviour because people value their approval or disapproval. Despite these observations, little research exists on the influence of social norms on diabetes risk-taking behaviours. We explored diet-related social norms and their influence on risk-taking behaviours for type 2 diabetes (T2D).
We conducted a multi-method qualitative study guided by the Social Norms Exploration Toolkit participatory tools. A total of 45 participants were interviewed for this study, including (10) T2D patients, (10) caregivers of T2D patients, (10) healthcare providers, (2) village health teams, (4) diabetes-free community members; (4) community influencers like cultural leaders and (5) family members. The study was conducted in eastern Uganda in the districts of Bugiri and Busia. Data were collected on health workers, caregivers, patients and community members using focus group discussions, in-depth interviews and non-participant observation. Data were manually analysed to identify emerging social norms and other information of interest following a thematic framework approach.
Most participants were aware that frequent consumption of fatty foods and sugary refined foods could increase one’s risk of getting T2D. The study highlights three themes: general awareness of T2D risk factors, common social norms influencing dietary behaviours and behavioural risk factors that are influenced by the social norms. The study highlights significant behavioural and social drivers of T2D, which include consumption of high-fat, high-sugar diets, limited exercise and stress. Gendered and cultural norms strongly influence dietary behaviours, with women preparing unhealthy foods to meet societal expectations, fearing sanctions like divorce or community stigma, while men’s dietary preferences were linked to respect and social status. Norms around staple food preferences and respect linked to weight further perpetuate T2D risk behaviours. Community influencers, family dynamics and cultural traditions reinforce these practices, underscoring the need for gender-transformative, culturally sensitive and community-centred interventions. However, healthcare providers and village health teams are critical for promoting healthier behaviours and reducing T2D prevalence.
Our deep-dive social norms diagnosis has revealed that even when people know the risk factors for T2D, they will still follow the social norm influence regarding lifestyles. Inclusive strategies that actively engage and reshape norms are therefore vital to reduce the prevalence of T2D.
Cognitive behavioural therapy (CBT) serves as a first-line treatment for internalising disorders (ID), encompassing depressive, anxiety or obsessive-compulsive disorders. Nonetheless, a substantial proportion of patients do not experience sufficient symptom relief. Recent advances in wearable technology and smartphone integration enable new, ecologically valid approaches to capture dynamic processes in real time. By combining ecological momentary assessment (EMA) with passive sensing of behavioural and physiological information, this project seeks to track daily fluctuations in symptom-associated constructs like affect, emotion regulation (ER) and physical activity. Our central goal is to determine whether dynamic, multimodal markers derived from EMA and passive sensing can predict treatment non-response and illuminate key factors that drive or hinder therapeutic change.
PREACT-digital is a subproject of the Research Unit FOR 5187 (PREACT), a large multicentre observational study in four outpatient clinics. PREACT channels state-of-the-art machine learning techniques identify predictors of non-response to CBT in ID. The study is currently running and will end in June 2026. Patients seeking CBT at one of four participating outpatient clinics are invited to join PREACT-digital. They can take part in (1) a short version with a 14-day EMA and passive sensing phase prior to therapy, or (2) a long version in which the short version’s assessments are extended throughout the therapy. It is estimated that 468 patients take part in PREACT-digital, of which 350 opt for the long version of the study. Participants are provided with a smartwatch and a customised study app. We collect passive data on heart rate, physical activity, sleep and location patterns. EMA assessments cover affect, ER strategies, context and therapeutic agency. Primary outcomes on (non)-response are assessed after 20 therapy sessions and therapy end. We employ predictive and exploratory analyses. Predictive analyses focus on classification of non-response using basic algorithms (ie, logistic regression and gradient boosting) for straightforward interpretability and advanced methods (LSTM, DSEM) to capture complex temporal and hierarchical patterns. Exploratory analyses investigate mechanistic links, examine the interplay of variables over time and analyse change trajectories. Study findings will inform more personalised and ecologically valid approaches to CBT for ID.
The study has received ethical approval from the Institutional Ethics Committee of the Department of Psychology at Humboldt Universität zu Berlin (Approval No. 2021–01) and the Ethics Committee of Charité-Universitätsmedizin Berlin (Approval No. EA1/186/22). Written informed consent will be obtained from all participants prior to enrolment. Results will be disseminated through peer-reviewed journals and presentations at national and international conferences.
