Abstract

Objective: To test the acceptability and effectiveness of a disability prevention intervention, Positive Minds-Strong Bodies (PMSB), offered by paraprofessionals to mostly immigrant elders in four languages.

Design: Randomized trial of 307 participants, equally randomized into intervention or enhanced usual care.

Setting: Community-based organizations in Massachusetts, New York, Florida, and Puerto Rico serving minority elders. Data collected at baseline, 2, 6, and 12 months, between May 2015 and March 2019.

Participants: English-, Spanish-, Mandarin-, or Cantonese-speaking adults, age 60+, not seeking disability prevention services, but eligible per elevated mood symptoms and minor to moderate physical dysfunction.

Interventions: Ten individual sessions of cognitive behavioral therapy (PM) concurrently offered with 36 group sessions of strengthening exercise training (SB) over 6 months compared to enhanced usual care.

Measurements: Acceptability defined as satisfaction and attendance to >50% of sessions. Effectiveness determined by changes in mood symptoms (HSCL-25 and GAD-7), functional performance (SPPB), self-reported disability (LLFDI), and disability days (WHODAS 2.0).

Results: Around 77.6% of intervention participants attended over half of PM Sessions; 53.4% attended over half of SB sessions. Intent-to-treat analyses at 6 months showed significant intervention effects: improved functioning per SPPB and LLFDI, and lowered mood symptoms per HSCL-25. Intent-to-treat analyses at 12 months showed that effects remained significant for LLFDI and HSCL-25, and disability days (per WHODAS 2.0) significantly decreased 6-month after the intervention.

Conclusions: PMSB offered by paraprofessionals in community-based organizations demonstrates good acceptability and seems to improve functioning, with a compliance-benefit effect showing compliance as an important determinant of the intervention response.
