This pilot feasibility randomized controlled trial will evaluate the feasibility, acceptability, safety, and preliminary effects of Dyadic STEP-SexPCare, a culturally tailored, nurse-led psychosexual programme for Hong Kong Chinese prostate cancer survivors and their female partners after primary treatment.
Approximately 72 couples (144 participants) will be randomized 1:1 at the couple level to Dyadic STEP-SexPCare plus standard prostate cancer survivorship care or standard survivorship care alone. Dyadic STEP-SexPCare contains six core components delivered over a planned 6 weeks, with an allowable 6-8-week completion window: four live nurse-led dyadic sessions and two self-paced modules. The programme addresses sexual recovery, couple communication, intimacy, mutuality, dyadic coping, emotional adjustment, sexual adaptation, and shared intimacy planning through a Screen-Tailor-Escalate-Plan approach.
Outcomes will be assessed at baseline before randomization, post-intervention at approximately Week 8, and 3 months after the intervention. The primary aim is to assess the feasibility, acceptability, safety, and implementation of the intervention and trial procedures. Secondary analyses will estimate preliminary between-group effects on sexual functioning, mutuality, dyadic coping, psychological distress, and quality of life to inform a future definitive randomized controlled trial.
