ABSTRACT=<sec id="sec1"><title>Objective</title><p>The purpose of this research was to design and psychometrically validate a new instrument (the Biobehavioural Pain and Movement Questionnaire/BioPMovQ), which assesses the relationship between pain and various factors related to motor behaviour from a biobehavioural perspective.</p></sec><sec id="sec2"><title>Methods</title><p>A mixed-method design combining a qualitative study with an observational and cross-sectional study was employed to develop (content validity) and psychometrically validate (construct validity, reliability and concurrent/discriminant validity) a new instrument. A total of 200 patients with chronic musculoskeletal pain were recruited.</p></sec><sec id="sec3"><title>Results</title><p>According to the exploratory factor analysis, the final version of the BioPMovQ consists of 16 items distributed across 4 subscales (1, disability, 2, self-efficacy for physical activity; 3, movement avoidance behaviours; and 4, self-perceived functional ability), all with an eigen value greater than 1, explaining 55.79% of the variance. The BioPMovQ showed high internal consistency (Cronbach’s <italic>α</italic> = 0.82; McDonald’s <italic>ω</italic> = 0.83). The intraclass correlation coefficient was 0.86 (95% confidence interval 0.76 to 0.91), which was considered to demonstrate excellent test–retest reliability. The standard error of measurement and minimal detectable change were 3.43 and 8.04 points, respectively. No floor or ceiling effects were identified. There was a positive, significant and moderate magnitude correlation with the Graded Chronic Pain Scale (<italic>r</italic> = 0.54), kinesiophobia (<italic>r</italic> = 0.60), pain catastrophising (<italic>r</italic> = 0.44) and chronic pain self-efficacy (<italic>r</italic> = −0.31).</p></sec><sec id="sec4"><title>Conclusion</title><p>The BioPMovQ showed good psychometric properties. Based on the findings of this study, the BioPMovQ can be used in research and clinical practice to assess patients with chronic musculoskeletal pain.</p></sec>
