Abstract

This research purposed to examine the relationship among worry, intolerance of uncertainty, and psychological flexibility levels of young adult individuals with a university degree and their demographic features, and to test the prediction of participants' worry levels in terms of these variables using hierarchical regression analysis. The sample of this correlational research consisted of 425 young adults (339F, 86M). The data of the study were obtained using the Demographic Information Form, the Penn State Worry Questionnaire, the Intolerance of Uncertainty Scale, and the Acceptance and Action Questionnaire-II during the COVID-19 pandemic period. The results of the study revealed that there were significant high-level relationships among the research variables. While participants' worry levels showed significant differences based on gender and monthly family income, they did not show significant differences based on age and current employment status. The hierarchical regression analysis conducted using a three-step model revealed that participants' worry levels were jointly predicted by the variables which gender, intolerance of uncertainty, and psychological flexibility, with intolerance of uncertainty contributing the most, explaining 39.5% of the total variance in worry. Lastly, the findings of the study were discussed and interpreted, and recommendations were provided for future studies.

Genç Yetişkinlerde Belirsizliğe Tahammülsüzlük ve Psikolojik Esnekliğin Endişeyi Yordaması

Abstract

Bu araştırma üniversite mezunu genç yetişkin bireylerin endişe, belirsizliğe tahammülsüzlük ve psikolojik esneklik düzeylerinin demografik değişkenlerle olan ilişkisini incelemeyi ve katılımcıların endişe düzeylerinin değişkenler açısından yordanmasını hiyerarşik regresyon analiziyle test etmeyi amaçlamıştır. İlişkisel araştırma yöntemiyle gerçekleştirilen bu araştırmanın örneklemi toplam 425 genç yetişkin bireyden (339K, 86E) oluşmaktadır. Araştırmanın verileri COVID-19 pandemisi döneminde Demografik Bilgi Formu, Penn Eyalet Endişe Ölçeği, Belirsizliğe Tahammülsüzlük Ölçeği ve Kabul ve Eylem Formu-II kullanılarak elde edilmiştir. Araştırmanın sonucunda, araştırma değişkenlerinin arasındaki ikili ilişkiler incelendiğinde üç değişkenin de birbiriyle yüksek düzeyde anlamlı ilişkisinin olduğu; katılımcıların endişe düzeylerinin, cinsiyete, aile aylık gelir düzeyine göre anlamlı farklılık gösterirken yaşa ve aktif çalışma durumuna göre anlamlı bir farklılık göstermediği; üç aşamalı modelle yapılan hiyerarşik regresyon analizi sonucunda ise katılımcıların endişe düzeylerini cinsiyet, belirsizliğe tahammülsüzlük ve psikolojik esneklik değişkenlerinin birlikte yordadığı ve bu değişkenlerden endişeyi en iyi açıklayan değişkenin toplam varyansa sağladığı %39,5’lik katkıyla belirsizliğe tahammülsüzlük olduğu sonuçlarına ulaşılmıştır. Son olarak araştırmadan elde edilen bulgular tartışılıp yorumlanarak sonraki çalışmalar için öneriler sunulmuştur.
