This study aimed to develop and articulate a logic model and programme theories for implementing a new cognitive–behavioural suicide prevention intervention for men in prison who are perceived to be at risk of death by suicide. Semi-structured one-to-one interviews with key stakeholders and a combination of qualitative analysis techniques were used to develop programme theories.

Interviews with 28 stakeholders resulted in five programme theories, focusing on: trust, willingness and engagement; readiness and ability; assessment and formulation; practitioner delivering the ‘change work’ stage of the intervention face-to-face in a prison environment; and practitioner training, integrating the intervention and onward care. Each theory provides details of what contextual factors need to be considered at each stage, and what activities can facilitate achieving the intended outcomes of the intervention, both intermediate and long term.

The PROSPECT implementation strategy developed from the five theories can be adapted to different situations and environments.

The aim was to evaluate an innovative pathway in police custody suites that aimed to specifically address alcohol-related health needs through screening and brief interventions by police custody staff. This paper presents a qualitative investigation of challenges involved in implementing the pathway. Qualitative interviews were carried out with 22 staff involved with commissioning and delivering the pathway; thematic analysis of interview data was then undertaken.

An overarching theme highlights the challenges and uncertainties of delivering brief alcohol interventions in the custody suite. These include challenges related to the setting, the confidence and competence of the staff, identifying for whom a brief intervention would be of benefit and the nature of the brief intervention.

Our findings show that there is a lack of clarity over how alcohol-related offending can be identified in police custody, whose role it is to do that and how to intervene.

Chemsex occurs primarily among gay, bisexual and other men who have sex with men (GBMSM), and there is evidence of a subgroup of users who carry out chemsex-related criminal offences and experience harm. Challenges with chemsex can present to various settings; there are concerns that harm is increasing, including at interfaces between health, social care and criminal justice systems. The UK response to date has lacked a coordinated approach. An expert reference group was convened to share chemsex knowledge, articulate priorities for research and pathway development, and foster collaborative working between agencies. It made three key recommendations: develop and increase training and awareness across all services; implement a coordinated research programme with the development of a common data-set and assessment tool to fully characterise population-level needs; develop a professional network to share information, provide professional support and act as a knowledge hub. There was support for a unified multi-agency strategy incorporating the priorities identified as overarching principles.
