Background: A therapeutic target for patients with chronic musculoskeletal pain is improvement in quality of life (QOL). However, factors associated with QOL are poorly understood.
Purpose: To explore factors affecting QOL among patients with chronic musculoskeletal pain.
Methods: This was a cross–sectional study. Participants were 166 patients that attended our hospital from April 2015 to March 2020. Data collected included participants’ age and scores on the Brief Pain Inventory (BPI), Pain Catastrophizing Scale, Pain Disability Assessment Scale (PDAS), Hospital Anxiety and Depression Scale, Pain Self–Efficacy Questionnaire (PSEQ), EuroQol Five Dimensions Questionnaire (EQ–5D), and Athens Insomnia Scale (AIS). Standardized (beta) regression coefficients showed significant associations between the independent variables (BPI, PDAS, PSEQ, and AIS scores) and the dependent variable (QOL measured using the EQ–5D). For the statistical analyses, we performed Shapiro–Wilk tests, descriptive statistics, paired t–tests, and multiple regression analysis with forward stepwise selection.
Results: The paired t–tests showed a significant difference between males and females only in PSEQ scores. Multiple regression analysis with forward stepwise selection yielded an R2 of 0.58.
Conclusions: We clarified that among patients with chronic musculoskeletal pain, QOL was closely related to pain levels, self–efficacy, pain disability, and sleep disorders.
