“…The questionnaire produces a total score with higher scores representing greater levels of pathological worry (19). The Farsi version of the questionnaire has been used in several previous studies and proven to be a valid and reliable measure [Cronbach's alpha = 85; (20,21)]. Cronbach's alpha in the current sample was = 0.78.…”

The COVID-19 pandemic has been associated with increased uncertainty, fear and worry in everyone's life. The effect of changes in daily life has been studied widely, but we do not know how emotion-regulation strategies influence adaptation to a new situation to help them overcome worry in the face of uncertainty. Here, 1,064 self-selected Farsi speaking participants completed an online battery of questionnaires that measured fear of virus and illness, worry, intolerance of uncertainty, and emotion regulation (two subscales: reappraisal, suppression). We also documented the number of daily COVID-19 cases and deaths due to COVID-19 on the day in which participants completed the questionnaire. Our findings suggest a correlation between contamination fear and the number of daily-confirmed cases (r = 0.11), and the number of reported deaths due to COVID-19 (r = 0.09). Worry mediated the relationship between intolerance of uncertainty and fear of virus and illness (b = 0.16, 0.1141 < CI < 0.2113). In addition, suppression moderated the relationship between intolerance of uncertainty and worry (p < 0.01). Our results suggest that suppression (at least in the short term) can be an adaptive response to the worry associated with uncertainty. Suppression can reduce worry, which in turn can decrease fear of contamination and improve adaptation to social distancing requirements. Although, the observed correlations were significant, but considering the sample size, they are not strong, and they should be interpreted cautiously.

“…The correlations between PTQ Total and subjective well-being, depression, and anxiety substantiated the validity of the scale. However, it was lower than in the first validation study using both clinical and nonclinical samples which showed no differences in the pattern of relationship between PTQ and anxiety/depression across sample type (Ehring et al, 2011) and in the general population study in Iran (Kami et al, 2019). However, these studies used self-report À2.9 (À3.5, À2.3) À1.9 (À2.9, À0.9)…”

Introduction: The Perseverative Thinking Questionnaire (PTQ) measures repetitive negative thinking and has been translated and validated in several countries. However, the PTQ has not been translated and validated in a Danish clinical sample. The aim of this paper was to evaluate the psychometric properties of the PTQ in a Danish clinical population and to introduce a shorter, 9-item version of the PTQ, the PTQ-9. Methods: Participants were recruited from a multicenter randomized clinical trial ( N = 251). They all completed the PTQ and World Health Organization 5-item Wellbeing Index (WHO-5). Participants were further assessed with the 6-item Hamilton Anxiety Rating Scale (HAM-A6) and the 6-item Hamilton Depression Rating Scale (HAM-D6). Results: The 2nd order factor model with one higher order general factor and three lower order factors showed the best model fit for the PTQ and the PTQ-9. Both versions showed good internal consistency and the expected correlations with the constructs used for validation. Furthermore, using WHO-5 as primary outcome, both the PTQ and PTQ-9 versions were able to discriminate between treatment responders and nonresponders. Conclusion: The PTQ and the PTQ-9 showed satisfying psychometric properties in a Danish clinical sample, including sensitivity to change, and could be used to evaluate psychotherapeutic treatment. To minimize the burden for the patients, the PTQ-9 may be recommended for clinical use over the PTQ.

“…The original validation study showed that the best factor structure of the PTQ was that of a second-order RNT factor and three first-order factors corresponding to the three features described before: (1) Core RNT Features, (2) Perceived Unproductiveness of RNT, and (3) RNT Capturing Mental Capacity (CFI = .950 -.980, RMSEA = .038 -.057; Ehring et al, 2011). This second-order structure was also replicated in Dutch-speaking undergraduates (Ehring et al, 2012), British patients with persecutory delusions (Cernis et al, 2016), Turkish non-clinical adults (Altan-Atalay & Saritas-Atalar, 2018), and Iranian clinical and non-clinical samples (Kami et al, 2019).…”

Background: The Perseverative Thinking Questionnaire (PTQ) is a global measure of repetitive negative thinking, a core transdiagnostic dimension of mental health. Objectives: This study sought to examine the factor structure, reliability, and evidence of associative validity of the PTQ in Peruvian undergraduates. Method: Data from 240 undergraduates (Mage = 20.33, 59% female) were evaluated with confirmatory factor analysis. After finding the best factor structure, reliability was estimated with coefficient omega. The correlation between the PTQ’s latent variable and cognitive fusion was examined as evidence of associative validity. Results: the PTQ proved to be essentially unidimensional since acceptable fit was obtained by the one-factor model with three correlations between errors (CFI = .945; RMSEA = .079). Reliability was high (ω = .927). The correlation between the PTQ and cognitive fusion was very large (ϕ = .876). Conclusion: The PTQ is an essentially unidimensional measure, thus only a global score should be computed. Associative validity should be further examined in future studies.
