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

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, η ² =.14; and psychosocial maladaptation, F (1.30, 31.93) = 8.01, p <.01, η ² =.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. [ABSTRACT FROM AUTHOR]
