Purpose The aim of this study was to evaluate the reliability, construct validity and predictive validity of the Hong Kong Chinese version of the Orebro Musculoskeletal Pain Screening Questionnaire (COMPSQ-HK). Methods The COMPSQ-HK was developed using the forward–backward translation. Internal consistency was assessed using Cronbach’s alpha and test–retest reliability was examined using intraclass correlation coefficient with one-way random-effects model (ICC1,1), minimum detectable change (MDC) and 95% limits of agreement (LoA). Construct validity was evaluated by correlating the COMPSQ-HK with the Numeric Pain Rating Scale, Roland-Morris Disability Questionnaire, Northwick Park Neck Pain Questionnaire, Tampa Scale for Kinesiophobia, and Medical Outcomes Study Short Form 12. The predictive validity was investigated using receiver operating characteristics (ROC) curve analyses with sick leave >60 days and return-to-work for ≥4 consecutive weeks as outcomes at 1 year follow-up. The areas under the curve (AUC) were calculated. Results The COMPSQ-HK was administered to 305 patients with acute/subacute low back pain and 160 patients with acute/subacute neck pain. The Cronbach’s alphas and ICC1,1 ranged from 0.83 to 0.84 and 0.81 to 0.92 respectively. The MDC were 32.1 and 21.1. The 95% LoA were −32.4 to 31.8 and −15.4 to 26.7. The Pearson r ranged from 0.333 to 0.697 in absolute value. The AUC for the ROC curve analyses ranged from 0.59 to 0.71. Conclusions The COMPSQ-HK has good internal consistency, moderate test–retest reliability, satisfactory construct validity and predictive validity as a screening tool for patients with back and neck pain at risk of chronic disability.
