Behavioral activation for late adolescents with subthreshold depression: a randomized controlled trial

Area of Science:

• Psychology
• Clinical Psychology
• Behavioral Science

Background:

• Subthreshold depression in adolescents is characterized by infrequent exposure to environmental rewards.
• Behavioral activation aims to increase engagement with positively reinforcing activities.

Purpose of the Study:

• To examine the efficacy of a brief behavioral activation program for subthreshold depression in late adolescents.
• To assess the impact of the intervention on depressive symptoms, quality of life, and behavioral characteristics.

Main Methods:

• A randomized controlled trial was conducted with 118 late adolescent university students (aged 18-19) diagnosed with subthreshold depression.
• Participants were randomly assigned to a 5-week behavioral activation treatment group or a control group.
• The primary outcome measure was the Beck Depression Inventory-II score.

Main Results:

• The treatment group demonstrated significant reductions in depressive symptoms compared to the control group (effect size -0.90).
• Improvements were also observed in self-reported quality of life and behavioral characteristics in the treatment group.
• The intervention proved effective despite its short duration and simple structure.

Conclusions:

• A low-intensity behavioral activation program is efficacious in alleviating depressive symptoms in adolescents.
• This cognitive behavioral therapy approach can be implemented effectively in various institutional settings.
• Future research should investigate the long-term effects of this intervention.
