Paternal incarceration represents a significant stressor that disrupts family cohesion, undermines paternal identity and adversely affects children’s psychosocial well-being. While family-focused programmes show promise in improving outcomes for incarcerated parents and their children, culturally attuned prison-based parenting interventions remain underdeveloped and scarce, particularly in Asian contexts. To address this gap, a local parenting intervention grounded in the Double ABCX model of family resilience, the ‘Be My Hero’ programme, was designed for incarcerated fathers in Hong Kong, China.

A concurrent mixed-methods design will be used to evaluate the intervention. A convenience sample of 20–30 incarcerated fathers of children aged 3–11 will be recruited from three correctional facilities. Quantitative measures assessing paternal competence, father–child attachment, communication and resilience will be collected preintervention and postintervention. Qualitative data will be triangulated through semistructured interviews with participants, their children and social workers, supplemented by session logs documenting perceived shifts in paternal identity and programme feasibility. The intervention is expected to mitigate disruptions in paternal identity and strengthen father–child bonds. This may, in turn, reduce intergenerational disadvantage and improve overall family well-being.

This study has received ethical approval from The University of Hong Kong. Informed consent and assent will be obtained from the participants, their children and current guardians. Findings will be disseminated through peer-reviewed journals or conferences to inform correctional rehabilitation practices, encouraging the integration of family-focused and resilience-based approaches. Stakeholders, including practitioners and policymakers, may adopt similar interventions to promote healthier re-entry outcomes and reduce intergenerational disadvantage.

Time-lapse imaging (TLI) systems for embryo incubation and assessment are hypothesised to improve the success rates of in vitro fertilisation (IVF) treatment by providing undisturbed culture conditions for embryos and/or providing more information on embryo development (morphokinetic parameters) to improve predictive accuracy for embryo selection. Despite numerous aggregate meta-analyses showing uncertainty of benefit, IVF clinics globally continue to invest significant resources into this technology with little translation of evidence into guidelines or policy frameworks. This may be attributed to heterogeneity in participant populations and/or variations in the use of TLI, as highlighted in the aggregate meta-analyses.

Our research proposal for evidence synthesis using individual participant data meta-analysis will provide greater power than aggregate meta-analysis to detect differential treatment effects for effectiveness (live birth, clinical pregnancy) and safety (pregnancy loss, multiple births, congenital malformations) outcomes across three comparisons (overall effect, undisturbed culture and morphokinetic parameters). We will also analyse if there are specific subgroups of women who may benefit from the intervention and if variations in use of the intervention show any benefits. We have incorporated the results of the literature search used for the latest Cochrane review (7 January 2019) into this review and will include all the trials included therein. We will further update the literature search to include new evidence by searching the electronic databases MEDLINE, EMBASE, CINAHL and CENTRAL from 07/01/2019 to date, outcomes for all ongoing trials reported in the 2019 Cochrane review, trial registers for newer ongoing/completed trials and the citation lists of all the newly identified trials for any relevant references. The search strategy will include a combination of subject headings and text words relating to or describing the participants and the intervention, with no language restrictions. Two authors will independently screen the titles and abstracts, and full text of articles retrieved from the search, to finalise a list of trials suitable for inclusion in the review. We will include randomised controlled trials that assess TLI systems for either undisturbed culture and/or use of morphokinetic parameters for embryo selection in women having IVF/ICSI treatment using their own oocytes.

Ethical approval is not required for this study. We plan to disseminate the findings of the research to all stakeholders, including the National Institute for Health and Care Excellence and other international guideline development groups, through publication in peer-reviewed journals, presentation at conferences, newsletters, meetings and websites of the funders, fertility charities and patient support groups.
