Abstract

Previous studies with undergraduates have provided support for the reliability and oblique three-factor structure of a new scale, the Pain Catastrophizing Scale (PCS). We examined the reliability and validity of the PCS in adult community and pain outpatient samples. The PCS showed a high internal consistency in both groups. Using data from the community sample, confirmatory factor analyses showed that the PCS taps a single construct characterized by three related dimensions. Gender differences were obtained on the PCS total score in the community and the outpatient samples. The analyses also showed significant differences between the community and the outpatient samples on the PCS total and subscales. Overall, the results showed strong evidence of criterion-related, concurrent, and discriminant validity for the PCS in the community sample. Limitations of the present study are discussed.

Cross-cultural adaptation, reliability, and validity of the German version of the Pain Catastrophizing Scale

“…The psychometric properties of our German version of the PCS were comparable to those reported by Osman et al and Van Damme et al (19)(20)(21), and exceeded those of the original English version (18). The PCS showed good internal consistency, and the 3-facture structure, reported in previous studies, could be replicated.…”

“…The Cronbach's alphas for the sum-scales and the total scale (0.67 to 0.92) were slightly higher than those reported in the original study of Sullivan (between 0.60 and 0.87) (18), and comparable to or a little lower than those previously reported for samples of outpatients and students (19). The similar values in different samples (19) is further endorsement of the good internal consistency of the German version of the questionnaire.…”

“…Confirmatory factor analysis, as described by van Damme (21) was used to evaluate model validity for 4 models: the 3-factor-model reported by Sullivan (18) (Table 4), closely followed by the 3-main axis factoring model reported by Sullivan (18) and Osman (19). …”

“…The Pain Catastrophizing Scale (PCS) was developed in the English language by Sullivan et al (18) to screen patients with catastrophizing thoughts, and to improve treatment planning, implementation and outcome assessment. The English version of the PCS has been well-investigated and its psychometric properties are good (18)(19)(20)(21). A systematic search of the literature revealed that, to date, no validated German version exists.…”

Does the fear avoidance model explain persistent symptoms after traumatic brain injury?

“…Catastrophizing about post-concussion symptoms was assessed with the Post-Concussion Symptoms Catastrophizing Scale (PCS-CS), which is an adaptation of the Dutch translation of the Pain Catastrophizing Scale (PCS) (38,39).The PCS has adequate psychometric properties (40) and is validated in acute and chronic whiplash disorders (41)(42)(43) and used in patients with mTBI by Khoury, et al (31). It consists of 13 items measuring the self-reported frequency of catastrophizing thoughts about the experienced pain with a 5 point Likert scale.…”
