About this study

This study will examine the effect of cognitive-behavioral group therapy, developed from an ecological systems perspective on intolerance of uncertainty on the coping skills of emerging adults experiencing individual and social uncertainties during their quarter-life crisis. The participants' intolerance of uncertainty, emotion regulation, and anxiety levels will be examined as outcome (dependent) variables in the intervention. The intervention will address uncertainties experienced in the micro, meso, exo, macro, and chrono systems of ecological systems. The data obtained as a result of the intervention will be evaluated in terms of the effects of the protocol developed on the outcome variables and the impact of sociopolitical factors on experiences of uncertainty and anxiety. The sample of the study will consist of university students in their adult years. The intervention process will be structured according to the basic principles of group therapy (universality, altruism, instilling hope, etc.). The intervention will be structured primarily around psychoeducation and skill building and will be preventive in nature. Quantitative and qualitative assessments are planned for the study.

Treatment and study plan

Extended Cognitive-Behavioral Group Intervention

Behavioral

This is an extended cognitive-behavioral group intervention designed to target intolerance of uncertainty. The program is informed by Ecological Systems Theory, emphasizing the interaction of individuals with their social and environmental contexts. It includes structured weekly sessions incorporating cognitive restructuring, behavioral experiments, exposure to uncertainty, and emotion regulation techniques. The intervention is delivered in a group format over 10 weeks.

Other names: CBT-Based Group Intervention for Intolerance of Uncertainty

Primary outcomes

  1. Intolerance of uncertainty

    Time frame: Baseline (pre-intervention) and immediately post-intervention (week 10)

    The Intolerance of Uncertainty Scale-12 will be used. The scale assesses the behavioral, emotional, and cognitive factors of intolerance of uncertainty. The overall score range for the scale is 12-60. Higher scores indicate a high level of intolerance for uncertainty.

Secondary outcomes

  1. Emotion regulation

    Time frame: Baseline (pre-intervention) and immediately post-intervention (week 10)

    The Emotion Regulation Difficulty Scale-Short Form (ERDS-16) will be used. The scale was developed to measure the difficulties individuals experience in regulating their emotions. The overall score range for the scale is 16-80. Higher scores indicate greater emotion dysregulation.

  2. Anxiety

    Time frame: Baseline (pre-intervention) and immediately post-intervention (week 10)

    State Anxiety Inventory-STAI-1 and Trait Anxiety Inventory-STAI-2 will be used. The overall score range for the scale is 20-80. Higher scores indicate greater anxiety.

  3. Worry

    Time frame: Baseline (pre-intervention) and immediately post-intervention (week 10)

    Penn State Worry Scale will be used. The scale assesses the tendency toward pathological anxiety. The overall score range for the scale is 16-80. A higher score indicates a higher level of pathological concern.
