A Pilot Feasibility Study of a Group-Based Remote-Delivered Dyadic Exercise Intervention in Hispanic Men With Prostate Cancer and Their Caregivers.

Accrual of eligible dyads to the HACER intervention was 75%.

• 14 eligible dyads were allocated to the intervention.
• This was a single-arm pilot study design.
• Participants were post-treatment Hispanic men with prostate cancer and their caregivers.
• The study used a Hispanic-adapted culturally relevant version of the Exercising Together© intervention.

Attendance at the 12-week remote group-based exercise intervention averaged 62%.

• The intervention involved resistance training three times a week.
• Sessions were delivered live and remotely in a group-based format.
• Retention was 79% with 95% assessment completion.
• Assessments were completed at baseline and post-intervention.

The HACER intervention was rated as acceptable by participants, with 86% reporting they would recommend the program to other dyads.

• Acceptability was a primary outcome of the study.
• Feasibility and acceptability were assessed as primary outcomes.
• The intervention was adapted to be culturally relevant for Hispanic dyads.
• The program was delivered remotely, supporting its potential scalability.

Self-reported physical activity level and objective physical function improved for both survivors and caregivers following the HACER intervention.

• Secondary outcomes included measures of physical and psychosocial health.
• Mean difference and effect sizes were calculated to determine intervention effects.
• Improvements were noted for both the prostate cancer survivors and their caregivers.
• Physical outcomes were assessed at baseline and post-intervention (12 weeks).

Caregivers demonstrated clinically significant improvement in depressive symptoms following the intervention.

• Depressive symptoms were measured as part of the psychosocial health secondary outcomes.
• The improvement was described as 'clinically significant' for caregivers.
• Psychosocial health was assessed at baseline and post-intervention.
• Modest improvements in physical and psychosocial health were noted, especially for Hispanic survivors.
