To establish the efficacy of the family-centered intervention in improving healthy lifestyle behaviors (MVPA and overall diet quality), as well as physical functioning, QoL, and family health climate, compared to survivor-only and control groups.

Primary Objectives

• Determine the extent to which MVPA and overall diet quality have improved in Black PCa survivors and their caregivers in the family-centered intervention group, compared to those in the survivor-only and control groups at post-intervention.

Secondary Objectives

• Determine the extent to which, compared to those in the survivor-only and control groups, both survivors and caregivers in the family-centered group maintain the MVPA and high diet quality at the 6-month follow-up, and experience improved 6MWT, QoL, and family health climate at both post-intervention and 6-month follow-up.
• Identify mediators and moderators of the family-centered intervention.
