Romanian Version of the Frustration Discomfort Scale (FDS): A Preliminary Validation on a Non-clinical Sample

Low frustration tolerance is one of the key concepts in rational emotional behavior therapy (REBT). The purpose of this study is to explore the factorial structure, reliability, and validity of the Romanian version of the Frustration Discomfort Scale (FDS), developed by Harrington (Clin Psychol Psychother 12(5):374-387, 2005b. https://doi.org/10.1002/cpp.465), within a non-clinical sample (N = 308) of Romanian teachers. For validation purposes, participants also completed several measures such as the Unconditional Self-Acceptance Questionnaire (USAQ) (Chamberlain and Haaga in J Ration Emot Cogn Behav Ther 19(3):163-176, 2001. https://doi.org/10.1023/A:1011189416600), Attitudes and Belief Scale 2 (ABS2) (DiGiuseppe et al. J Ration Emot Cogn Behav Ther 36(1):47-79, 2018. https://doi.org/10.1007/s10942-017-0273-3), Teacher Irrational Belief Scale (TIBS) (Bernard Teacher irrationality and teacher stress, 24th international congress of psychology, Sydney, Australia, 1988), and Pupil Control Ideology Scale (PCI) (Willower et al. The school and pupil control, The Pennsylvania State University, 1967). Confirmatory factor analysis (CFA) suggests that the initial four-factor solution from the scale development study received similar support to the one-factor solution found in some previous studies. Patterns of correlations linking the FDS total sum score versus the FDS 4-factor scale scores with other variables provide some support for the one-factor solution, mainly because it is a more parsimonious solution. Differentiating between several subcomponents of FDS does not bring discriminant validity in our non-clinical sample. Based on current preliminary validation, the FDS is a reliable and valid instrument for assessing frustration discomfort in a Romanian-speaking population as a single-factor construct. Our results do not exclude the possibility that future discriminant validity endeavors could support the utility of treating low frustration tolerance as a multidimensional construct since using a non-clinical sample is likely to impact the factorial structure of the FDS.
