BackgroundBuilding partnerships between mental health services and Black faith communities to co-produce culturally tailored interventions is an essential step towards improving access to services and reducing stigma among the Black population. Given that Black faith organisations are considered a primary source of emotional and psychological support they are well positioned as ‘gatekeepers’ for services, to overcome barriers to engagement and build trusting relationships with the Black community. The aim of this paper is to pilot a manualised mental health awareness and stigma reduction intervention for Black faith communities in the UK, and to make an initial assessment of feasibility, acceptability and outcomes.MethodsThis study employed a mixed methods pre–post-design, based upon the Medical Research Council Framework (MRC) for complex interventions, and the Implementation Science Research Development.ResultsThe qualitative assessments indicate that the intervention was found overall to be acceptable and feasible to the Black faith community population. This pilot study did not find statistically significant changes for the Mental Health Knowledge schedule (MAKS), Reported and Intended Behaviour Scale (RIBS), intended help-seeking or willingness to disclose (Attitudes to Mental Illness Survey) measures. However, the direction of all the non-significant changes in these measures suggests positive changes in mental health knowledge, a reduction in participants’ desire for social distance, and greater willingness to disclose personal experiences of mental health problems. A statistically significant improvement in the Community Attitudes towards Mental Illness (CAMI) scale results indicated a lower level of stigmatising attitudes towards people with lived experience of mental health conditions (PWLE), and an increase in tolerance and support towards PWLE after the intervention. Significant improvement in the willingness to disclose measure suggests increased preparedness to seek help amongst participants, a lesser desire for social distance, and greater willingness to engage with PWLE after the intervention. Three key themes, including 9 subthemes were identified from the qualitative data analysis: (i) initial implementation and intention to adopt; (ii) perceived suitability and usefulness of intervention to address cultural issues relating to mental health in the Black community; and (iii) strengthening the capacity of faith leaders.ConclusionsThis ON TRAC pilot study shows that the intervention was feasible and acceptable, and that it has promising positive impacts and next requires larger scale evaluation. These results demonstrate that the intervention was a culturally acceptable way to potentially increase mental health awareness and reduce stigma in Black faith communities.Trial registrationISRCTN12253092.
