Enduring effects of a 5-week behavioral activation program for subthreshold depression among late adolescents: an exploratory randomized controlled trial.

Background: No significant effect of psychological treatment has been reported from meta-analysis of subthreshold depression patients and control subjects at 1-year follow-up. However, behavioral activation is a simpler and more cost-effective treatment than cognitive behavioral therapy. The primary purpose of this study was to assess by comparison to an assessment-only control group whether the effects of behavioral activation program for depressive symptoms can persist up to 1-year follow-up without the use of antidepressants or other psychotherapy.

Detailed course of depressive symptoms and risk for developing depression in late adolescents with subthreshold depression: a cohort study.

Purpose: Despite its clinical importance, adolescent subthreshold depression remains a largely neglected topic. The aims of this study were to accurately identify the natural course of depressive symptoms and the risk for developing major depressive episode (MDE) in late adolescents with subthreshold depression over 1 year.

Patients And Methods: One hundred and seventy-two participants <20 years of age (mean age: 18.

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

The main behavioral characteristic of subthreshold depression that is observed in adolescents is the low frequency of exposure to environmental rewards. Therefore, it was considered that a simple intervention conducted in short sessions, focusing on increasing access to positively reinforcing activities, would be efficacious in increasing the availability of rewards. We conduct a randomized controlled trial to examine the efficacy of such a behavioral activation program that was conducted weekly for 5 weeks in 60-min sessions.

Mechanisms of behavioral activation for late adolescents: Positive reinforcement mediate the relationship between activation and depressive symptoms from pre-treatment to post-treatment.

Background: It is suggested that there is some support for notion that frequency of activity can lead to improved mood in behavioral activation, but this research is relatively imprecise. We investigated whether positive reinforcement mediates the relationship between activation and alleviation of depressive symptoms

Methods: Late adolescents with sub-threshold depressive symptoms participated in the study. We conducted an intervention using behavioral activation with the participants.

fMRI Study of Social Anxiety during Social Ostracism with and without Emotional Support.

Social anxiety is characterized by an excessive fear of being embarrassed in social interactions or social performance situations. Emotional support can help to decrease or diminish social distress. Such support may play an important role at different points of social interaction.

Behavioral characteristics of subthreshold depression.

Background: This study examines differences in behavioral characteristics among individuals who are not depressed and individuals with subthreshold depression, and depression.

Methods: We conducted structured interviews with 111 undergraduate students, who also completed self-report scales. The participants were divided into a non-depression group, a subthreshold depression group, and a depression group based on results of the structured interview and the BDI-II.
