Dropout from interdisciplinary pain management programmes is reported to be high. This may result in poor treatment outcomes. Therefore, paying attention to the prevention of dropout is important. This systematic review presents an overview of predictors of dropout (mainly patient characteristics) and makes suggestions for future research on this topic. Objective: Systematic review to identify predictors for dropout during interdisciplinary pain management programmes.

Interdisciplinary pain management programmes have high dropout rates. Patient dropout from these programmes is associated with poor treatment outcomes and high financial costs for society. To improve the overall effectiveness of these programmes more insight is needed into predictors of dropout. This study explored whether patient beliefs (emotional and cognitive) about illness and treatment are related to dropout. The results revealed that patients with chronic pain who catastrophize were more prone to dropout.

Background Accurate measurement of health literacy is essential to improve accessibility and effectiveness of health care and prevention. One measure frequently applied in international research is the Short Assessment of Health Literacy (SAHL). While the Dutch SAHL (SAHL-D) has proven to be valid and reliable, its administration is time consuming and burdensome for participants. Our aim was to further validate, strengthen and shorten the SAHL-D using Rasch analysis. Methods Available cross-sectional SAHL-D data was used from adult samples ( N = 1231) to assess unidimensionality, local independence, item fit, person fit, item hierarchy, scale targeting, precision (person reliability and person separation), and presence of differential item functioning (DIF) depending on age, gender, education and study sample. Results Thirteen items for a short form were selected based on item fit and DIF, and scale properties were compared between the two forms. The long form had several items with DIF for age, gender, educational level and study sample. Both forms showed lower measurement precision at higher health literacy levels. Conclusions The findings support the validity and reliability of the SAHL-D for the long form and the short form, which can be used for a rapid assessment of health literacy in research and clinical practice.
