Pain catastrophizing often has been measured using the Pain Catastrophizing Scale (PCS). Studies of the PCS nearly consistently support its three-factor structure (i.e., helplessness, magnification, and rumination) and satisfactory psychometric properties across different countries and languages. This study aimed to assess the generalizability of the three-factor structure of the PCS to Korean patients with chronic non-cancer pain and to investigate reliability, measurement error, and construct validity of a Korean version of the PCS (K-PCS). ⋯ The K-PCS has the reliability, measurement error, and construct validity support for assessing pain catastrophizing in a Korean patient sample with chronic non-cancer pain.

It has been well established that how irritable bowel syndrome (IBS) patients respond to their illness experiences (physical, psychological) has a great impact on their symptoms, psychosocial functioning and quality of life. Recently it has been shown that using acceptance coping strategies (rather than control coping strategies) is linked to positive outcomes in several chronic illness contexts (e.g. chronic pain, diabetes, epilepsy).This study is intended to evaluate the factor structure and other psychometric properties of an acceptance measure adapted for the IBS population (IBSAAQ) and to investigate its possible utility in the prediction of key IBS outcomes. ⋯ The IBSAAQ is a valid and reliable measure of acceptance in IBS. This measure might be of use for the study of the impact of coping strategies on outcomes in IBS and of the effectiveness of acceptance-based approaches (e.g. acceptance and commitment therapy).
