| Popis: | SELPHI involves two interventions: (A) It provides one HIV self-testing (HIVST) kit (B) It offers 3-monthly repeat HIVST kits if participants report ongoing risk. A logic model underpinned by the Behaviour Change Wheel informed the design of the intervention. SELPHI recruited 10,135 cis-men and trans people in England and Wales, all reporting anal sex with a man. This paper explores how the interventions were experienced and the pathways to impact for different groups of trial participants. In-depth interviews with 37 cis-men who have sex with men (MSM) were used to inductively categorise participants based on sexual and HIV testing histories. Themes relating to intervention experiences and impacts were mapped onto SELPHI-hypothesised intermediate outcomes to consider intervention impacts. Three groups were identified: &lsquo Inexperienced testers&rsquo engaged with SELPHI to overcome motivational and social and physical opportunity testing barriers. For &lsquo pro self-testers&rsquo testing frequency was constrained by psychological and social barriers and lack of opportunity. &lsquo Opportunistic adopters&rsquo engaged in HIVST for novelty and convenience. Perceived impacts for inexperienced testers were most closely aligned with the logic model, but for opportunistic adopters there was little evidence of impact. Distinctive groups were discernible with divergent intervention experiences. Using COM-B as a model for understanding behaviour change in relation to HIVST, our results indicate how HIVST interventions could be adapted to respond to different needs based on the target population&rsquo s demographic and behavioural features. |
