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).

To evaluate the impact of race/ethnicity on the relationship between body mass index (BMI) and health-related quality of life (HRQOL) among blacks, Hispanics, and whites. ⋯ BMI was associated with worse physical HRQOL to a similar degree among blacks, Hispanics, and whites. This finding suggests that interventions leading to obesity reduction should be associated with substantial and equal improvements in the physical HRQOL of all race/ethnicity groups.

Patient-reported outcomes in randomized clinical trials: development of ISOQOL reporting standards.
To develop expert consensus on a suite of reporting standards for HRQL outcomes of RCTs. ⋯ ISOQOL has developed a suite of recommended standards for reporting PRO results of RCTs. Improved reporting of PROs will enable accurate interpretation of evidence to inform patient choice, aid clinical decision making, and inform health policy.

The aim of this study was to translate and adapt the Italian version of the Chronic Pain Coping Inventory (CPCI) and validate the translation in subjects with chronic non-specific pain of the locomotor system. ⋯ The CPCI was successfully translated into Italian and proved to have a good factorial structure and psychometric properties similar to the original and adapted versions. The use of the Italian version of the CPCI is recommended for clinical and research purposes.
