We investigated the mediator roles of risk factors (intolerance of uncertainty, negative metacognition, and negative prospections) and protective factors (positive prospections and psychological resilience) together on the link between COVID-19-related feelings and behaviors, thoughts, and precautions taken and psychological symptoms with an integrative approach in Turkey. The online sample consisted of Turkish adults. The results of path analyses indicated that feelings and behaviors related to COVID-19, thoughts about COVID-19, and precautions taken related to COVID-19 are significantly associated with intolerance of uncertainty. Intolerance of uncertainty is significantly associated with negative metacognition, negative and positive prospections, psychological symptoms, and psychological resilience. Negative metacognition, negative and positive prospections, and psychological resilience are significantly associated with psychological symptoms. Mediation analysis demonstrated that intolerance of uncertainty significantly mediated the relationship between feelings and behaviors related to COVID-19, thoughts about COVID-19, and precautions taken related to COVID-19 and negative metacognition, psychological resilience, positive and negative prospections, and psychological symptoms. Lastly, negative metacognition, psychological resilience, positive and negative prospections significantly mediated the relationship between intolerance of uncertainty and psychological symptoms. Implications for mental health providers are discussed.
