Brief summary

This study will examine the effect of cognitive-behavioral group psychotherapy, structured within the framework of ecological systems theory, on adults' intolerance of uncertainty.

Detailed description

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.

Design outcomes

Primary

MeasureTime frameDescription
Intolerance of uncertaintyBaseline (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

MeasureTime frameDescription
Emotion regulationBaseline (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.
AnxietyBaseline (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.
WorryBaseline (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.
