Study Overview
Brief Summary
This study will determine the feasibility and acceptability of a 12-week dyadic culinary nutrition program among Hispanic prostate cancer survivor/caregiver dyads using a randomized controlled trial design.
Detailed Description
Prostate cancer is the most common cancer among Hispanic/Latino men. Following treatment, both survivors and their family caregivers often experience long-term side effects that can be managed through diet. However, few survivors or caregivers meet current nutritional guidelines, and most interventions focus solely on the patient. Because co-residing couples share meals and routines, targeting the survivor-caregiver dyad together may be more effective for dietary modification. This pilot study evaluates "Cooking Healthy - Engaging Families" (CHEF), a remote, dyadic culinary nutrition program designed to improve dietary intake for Hispanic prostate cancer survivors and caregivers.
This pilot study utilizes a randomized controlled trial (RCT) design to determine the feasibility and acceptability of the CHEF intervention.The study aims to recruit 20 dyads (n=40 total participants) meeting the following criteria:
Survivors: Hispanic men post-treatment for prostate cancer (≥ 6 weeks from completion of primary curative treatment).
Caregivers: Informal, co-residing caregivers of the enrolled survivors.
Participants will be randomized to evaluate the program's delivery, engagement, and acceptability in a remote format. Additionally, the study will explore secondary outcomes, including changes in dietary intake and serum carotenoid levels.

Intervention
Dyadic culinary nutrition program
Intervention: Cooking Healthy - Engaging Families (CHEF) (Behavioral)
Education Control
Nutrition education
Intervention: Control (Behavioral)
Outcomes
Primary Outcomes
Feasibility measured by enrollment rate
Time Frame: Up to 12 weeks
Will be determined as the enrollment rate- the number of dyads enrolled out of those approached and eligible using descriptive statistics.
Appropriateness measured by retention rate
Time Frame: Up to 24 weeks
Will be determined as the retention rate- calculated as the number of dyads (survivor-caregiver pairs) completing the study versus dyads consented using descriptive statistics.
Acceptability measured by adherence rate
Time Frame: Up to 12 weeks
Acceptability will be measured by adherence rate to the intervention calculated as the total number of classes attended divided by the total possible schedule the patient could attend using descriptive statistics.
Composite measure of implementation success
Time Frame: 12 weeks
Implementation success will be measured by a single composite questionnaire that will determine the extent to which the intervention is considered feasible, appropriate, and acceptable. Responses are summary scored with a possible range of 4-20; higher scores indicate greater feasibility, appropriateness, and acceptability.
Secondary Outcomes
- Fruit and Vegetable Servings(Baseline, 12 weeks, 24 weeks)
- Concentration of Carotenoid Biomarkers(Baseline, 12 weeks, 24 weeks)
