Effects of a group music-based intervention in improving attachment and psychosocial adaptation in adolescents with parental attachment insecurity: A randomized trial

Abstract

The effects of a group music-based intervention on attachment and psychosocial adaptation in adolescents with parental attachment insecurity were examined in Taiwan. A randomized controlled trial with a pre–post and follow-up design was performed. The music group ( N = 28) attended a 40-min session twice weekly for 10 weeks. The nonmusic group ( N = 28) received health education. The groups underwent a parental attachment and psychosocial adaptation assessment before and after the music intervention and at the 1-week follow-up. The results were analyzed using paired-samples t-tests and a mixed analysis of variance. Fifty-four participants completed both the pre- and posttests and were included in the final data analysis. The interaction effect was statistically significant, parental attachment, F(1.07, 25.81) = 8.18, p < .005, η2 = .14; and psychosocial maladaptation, F(1.30, 31.93) = 8.01, p < .01, η2 = .13, scores, implying a successful intervention. A significant difference in the postintervention parental attachment, F(1.03, 25.81) = 19.19, p < .001, and psychosocial maladaptation, F(1.28, 31.93) = 14.22, p < .001, scores was found between the music and nonmusic groups. The present study confirmed that group music-based interventions may effectively improve adolescents’ parental attachment and mitigate their psychosocial maladaptation.
