Changes in Affective Network Variability Among Youth Treated for Anxiety Disorders.

Area of Science:

• Psychology
• Clinical Psychology
• Developmental Psychology

Background:

• Cognitive behavioral therapy (CBT) is effective for youth anxiety, but the change process requires further investigation.
• Affective network variability, the spread of emotions over time, is linked to anxiety but its treatment response is unknown.
• Dynamical systems theory offers a framework to study emotional fluctuations during therapy.

Purpose of the Study:

• To investigate changes in affective network variability during CBT versus client-centered therapy (CCT) in anxious youth.
• To determine if affective network changes are specific to CBT or general treatment effects.
• To examine the association between affective patterns and treatment outcomes.

Main Methods:

• Ecological momentary assessment (EMA) data collected via cell phone from 114 youth (aged 9-14) with anxiety disorders.
• Dynamical systems framework used to model affective network variability over the course of CBT and CCT.
• Analysis of pretreatment and in-treatment affective patterns and their relation to treatment outcomes.

Main Results:

• Youth receiving CBT showed significant decreases in affective network variability.
• No significant decrease in affective network variability was observed in youth receiving CCT.
• Changes in affective network variability did not predict treatment outcomes.

Conclusions:

• Findings support the dynamical systems approach for understanding treatment-related changes in emotional regulation.
• Affective network variability may be a mechanism specific to CBT's efficacy in reducing anxiety.
• Further research is needed to explore the predictive value of affective changes on long-term outcomes.
