Abstract 6307: Feasibility of a survivorship app for black prostate cancer survivors: Results from a 12-week mHealth pilot study

Q: What is the clinical evidence from this study?

Study design: Other. Population: Prostate cancer (n=9). Intervention: SAFE-CaPS (Survivorship App for Ethnically Diverse Black Prostate Cancer Survivors). Primary outcome: Feasibility (adherence rates ≥70% of daily diary entries).

Key Result

The SAFE-CaPS mHealth app was feasible and well accepted among Black prostate cancer survivors, with 44.4% (4 of 9) meeting the ≥70% daily diary adherence threshold over 12 weeks.

Key Points

This study aims to evaluate the feasibility and impact of a mobile health app for Black prostate cancer survivors.
Conducted a 12-week pilot study with nine Black prostate cancer survivors.
Participants used the SAF-CaPS app for symptom and behavior tracking, with daily prompts.
Evaluated feasibility based on adherence rates and assessed mental health and quality of life through surveys and interviews.
Four participants met the feasibility threshold and eight completed the study.
Quality of life improved from week 1 to week 12, while social well-being declined over time.
Key issues included severe sexual dysfunction, low physical activity, and moderate depression among participants.

Structured PICO

Is the SAFE-CaPS mobile health app feasible and acceptable for improving self-monitoring behaviors and health outcomes in Black prostate cancer survivors?

Population

9 Black prostate cancer survivors (seven U.S.-born, one African-born, and one Caribbean-born)

Intervention

Survivorship App for Ethnically Diverse Black Prostate Cancer Survivors (SAFE-CaPS) providing daily prompts for symptoms and behavior tracking, brief self-management support, and physician alerts for 12 weeks

Outcome

Feasibility (adherence rates ≥70% of daily diary entries), engagement, and acceptabilitypatient reported

A 12-week pilot study demonstrated that a culturally tailored survivorship app is feasible and acceptable for Black prostate cancer survivors, while identifying key unmet needs in sexual dysfunction, physical activity, and depression.

Abstract

Abstract Introduction: Black prostate cancer (CaP) survivors experience unique quality-of-life (QoL) and recovery challenges after treatment compared with their White counterparts. Smartphone-delivered mobile health interventions offer promising avenues for symptom tracking and lifestyle changes; but their feasibility, user engagement, and acceptability in this population remain unclear. This study assessed the feasibility, engagement, and preliminary impact of the Survivorship App for Ethnically Diverse Black Prostate Cancer Survivors (SAFE-CaPS), designed to improve self-monitoring behaviors and health outcomes. Methods: Nine Black CaP survivors (seven U. S. -born, one African-born, and one Caribbean-born) participated in a 12-week pilot study of SAFE-CaPS. The app provided daily prompts for symptoms (pain, sleep, fatigue, sexual function, anxiety, depression) and behavior tracking (physical activity, diet), brief self-management support, and physician alerts for severe symptom reports. Mental health (GAD-7 and PHQ-9) and QoL (FACT-P) were assessed at baseline and after 12 weeks. Feasibility was evaluated based on adherence rates (i. e. , ≥70% of daily diary entries). Engagement and acceptability were assessed via app analytics and qualitative interviews on usability and cultural relevance. Participants were compensated up to 125 via Greenphire ClinCard. Surveys were analyzed with SPSS v29, and interviews with Atlas. ti v23. Results: Participants’ median age at diagnosis was 56 years; six had a positive family history of CaP, and four had undergone radical prostatectomy. Four participants met the feasibility threshold, and eight completed the study. Most daily entries reflected mild pain, fatigue, bowel and urinary issues, and generally good sleep. Several participants frequently reported severe sexual dysfunction, and most diary responses indicated 20 minutes of physical activity per day. Fruit/vegetable intake was low, with about half of daily responses showing 1-2 servings. At baseline, eight participants had minimal anxiety, while five had moderate depression. Overall, QoL improved from week 1 to week 12 in physical, emotional, and functional well-being, while social well-being declined over time. Interviews emphasized the app’s user-friendly design, ease of navigation, and acceptability as key strengths, with several participants highlighting its simplicity and ease of use, with recommendations to reduce repetitive items and address minor technical issues. Conclusions: SAFE-CaPS was feasible and well accepted. Sexual dysfunction, low physical activity, and moderate depression emerged as key concerns, heightening the need for integrated mental health, activity support, and stronger engagement strategies in future mHealth interventions.
