Psychometric properties revised reinforcement sensitivity theory (r-RST) scale in chronic pain patients

OBJECTIVE: The aim of present study was to evaluate the psychometric properties of the Reinforcement Sensitivity Questionnaire (RSQ) in patients with chronic pain. METHODS: For this purpose, 312 (first study) and 70 (second study) patients with chronic pain were selected, and the Reinforcement Sensi...

description OBJECTIVE: The aim of present study was to evaluate the psychometric properties of the Reinforcement Sensitivity Questionnaire (RSQ) in patients with chronic pain. METHODS: For this purpose, 312 (first study) and 70 (second study) patients with chronic pain were selected, and the Reinforcement Sensitivity Theory Personality Questionnaire (RST-PQ) and Pain Beliefs and Perceptions Inventory (PBPI) were distributed among them for their response. The reliability of the questionnaire was evaluated by Cronbach’s alpha, retest, and split-half coefficient; then, the criterion validity with other questionnaires was evaluated to determine the psychometric properties of the RSQ. The factor structure was assessed via confirmatory factor analysis. RESULTS: The results of the factor analysis indicated that the RSQ has five factors, and checking the validity by using Cronbach’s alpha, retest, and split-half coefficient reflected the stability of the scale; the criterion validity of the RSQ with other questionnaires showed desirable discriminant and convergent validity. CONCLUSION: Overall, the findings indicated that the RSQ has good psychometric properties in chronic pain samples, and the tool can be used in studies of chronic pain. It seems that the RSQ is a good predictor for pain in patients with chronic pain.
