Problem-solving skills training for vulnerable families of children with persistent asthma: report of a randomized trial on health-related quality of life outcomes

Abstract

Objectives: To test the efficacy of problem-solving skill training (PST) in improving health-related quality of life (HRQOL) of children with persistent asthma from predominantly lower socioeconomic status (SES) Spanish-speaking Hispanic families.

Methods: Randomized controlled trial comparing standard care waitlist (SC) control, home-visiting asthma education/care coordination (CC), and combined intervention (CC + PST) at baseline, after intervention, and 6-month follow-up. The primary outcome was parent proxy-report child HRQOL (PedsQL).

Results: Participants (n = 252) were 83.3% Hispanic and 56.3% monolingual Spanish speakers, and 72.6% of mothers had not graduated high school. We found a significant (P = 0.05) intervention effect for parent proxy-reported child generic (but not asthma-specific) HRQOL, with CC + PST superior to SC [83.8 vs 79.8; adjusted mean difference of 4.05 points (95% confidence interval 0.63-7.4], but no difference between the CC and SC groups.

Conclusions: In this sample of vulnerable families of children with persistent asthma, a CC + PST intervention was efficacious in improving children's generic HRQOL.
