Outcome measures for fear of movement in individuals with musculoskeletal disorders: a systematic review with meta- analysis.
Abstract
Fear of movement is a significant psychological factor in musculoskeletal disorders and can negatively affect clinical outcomes. Several assessment tools are currently available to measure fear of movement. This systematic review aimed to analyze and compare the psychometric properties of the main scales used in populations with musculoskeletal disorders. A systematic literature review was conducted according to PRISMA guidelines. Studies were identified through MEDLINE (via PubMed), CINAHL (via EBSCO), Web of Science, and Scopus. Methodological quality was assessed using the COSMIN checklist. A meta-analysis was performed on studies reporting internal consistency. 99 studies were included, identifying a total of 29 assessment tools. Most instruments demonstrated good reliability and validity. However, substantial heterogeneity in methodological quality was observed, together with limited reporting of measurement error and responsiveness across studies. Numerous tools are available for assessing fear of movement, with some scales showing high levels of reliability and validity across different clinical and linguistic contexts. These findings provide useful guidance for selecting appropriate instruments for clinical practice and research, supporting improved assessment and management of fear of movement in patients with musculoskeletal pain. www.crd.york.ac.uk/prospero identifier is CRD420251009756.
Clinical relevance
Which self-report outcome measures for fear of movement demonstrate the strongest and most consistent psychometric properties (reliability, validity, measurement error, and responsiveness) for use in individuals with musculoskeletal disorders? __SNAPSHOT__ {"studyDesign":"Systematic review with meta-analysis (PRISMA-compliant) of psychometric validation studies","setting":"Multinational; no single institution or clinical setting — searches conducted across MEDLINE (via PubMed), CINAHL (via EBSCO), Web of Science, and Scopus","sampleSize":"99 studies included; individual study sample sizes not reported in the abstract","population":"Individuals with musculoskeletal disorders across varied clinical and linguistic contexts; specific diagnostic subgroups, age ranges, and chronicity profiles not detailed in the abstract","intervention":"Assessment tools (patient-reported outcome measures) designed to measure fear of movement (kinesiophobia, pain-related fear, fear-avoidance); 29 distinct instruments identified","comparator":"Head-to-head comparison of psychometric properties across available instruments; no therapeutic intervention or placebo comparator","primaryOutcome":"Psychometric properties of fear-of-movement scales as appraised by the COSMIN checklist: internal consistency (meta-analyzed), reliability, validity (structural, construct, cross-cultural), measurement error, and responsiveness","followUp":"Not applicable (cross-sectional psychometric appraisal); individual study follow-up durations not reported in the abstract","fundingSource":"Not reported"}
Key findings
Ninety-nine studies were included, collectively identifying 29 distinct assessment tools for fear of movement in musculoskeletal disorder populations. Most instruments demonstrated good reliability and validity across studies. A meta-analysis was performed specifically on studies reporting internal consistency (the only domain pooled quantitatively), though pooled Cronbach's alpha estimates, confidence intervals, heterogeneity statistics (I²), and p-values are not reported in the abstract. Substantial heterogeneity in methodological quality was observed across studies according to COSMIN appraisal. Measurement error and responsiveness were the most poorly and inconsistently reported psychometric domains. Clinically important adverse events are not applicable to this psychometric review. No NNT or NNH is calculable. The abstract does not specify which among the 29 instruments performed best overall, nor does it report instrument-specific pooled effect estimates.
Practice implications
This review establishes that a large and heterogeneous landscape of 29 tools exists for measuring fear of movement in musculoskeletal populations, with some scales demonstrating high reliability and validity across diverse clinical and linguistic settings. It does not establish a definitive hierarchy of instruments, does not specify which tools are superior for which diagnostic subgroups (e.g., low back pain vs. post-surgical orthopedic patients vs. osteoarthritis), and does not confirm that any instrument is adequately responsive to clinically meaningful change — a critical gap for use as a treatment outcome measure. Patients in subgroups underrepresented in validation literature (e.g., pediatric populations, individuals with acute rather than chronic pain, non-Western linguistic contexts) cannot be assumed to be well served by the existing evidence base. The finding of substantial methodological heterogeneity limits confidence in cross-instrument comparisons. Clinicians selecting a scale for routine practice or clinical trials should prioritize instruments with COSMIN-verified good structural validity, internal consistency, test-retest reliability, and at minimum some data on responsiveness — properties not universally confirmed across all 29 tools. Practice should not change based on this abstract alone; the full publication is needed to identify specific instrument recommendations. NOTE: Only the abstract was available for this summary; the full data tables, instrument-specific meta-analytic estimates, and COSMIN rating summaries are not accessible and may substantially alter interpretation. __LIMITATIONS__ Only the abstract was available; instrument-level pooled estimates, COSMIN ratings per scale, and full heterogeneity statistics cannot be evaluated.,Substantial methodological heterogeneity in included studies limits the interpretability of pooled meta-analytic internal consistency estimates.,Meta-analysis was restricted to internal consistency only; other critical psychometric domains (measurement error, responsiveness) were too inconsistently reported to be pooled, representing a major gap for clinical utility as outcome measures.,The 29 instruments likely vary considerably in their target constructs (kinesiophobia, fear-avoidance beliefs, pain-related fear), and lumping them into a single review may obscure important conceptual and measurement distinctions.,Generalizability is uncertain: validation studies are often conducted in convenience samples from specific diagnostic and linguistic populations, limiting extrapolation across the breadth of musculoskeletal disorders.,Publication bias in psychometric validation studies favors positive results; instruments with poor properties may be underrepresented.,No assessment of the minimal clinically important difference (MCID) or cutoff scores is described, limiting translational utility.,Funding source is not reported, and institutional affiliations of the research team may introduce selection or reporting biases.,Cross-cultural validity and measurement invariance — prerequisite for interpreting scores across languages — are not described as consistently evaluated across all instruments. __BOTTOM_LINE_CATEGORY__ potentially_practice_informing __BOTTOM_LINE__ This PRISMA-compliant systematic review and meta-analysis identified 29 assessment tools for fear of movement in musculoskeletal disorders, with most demonstrating adequate reliability and validity, but with substantial variation in methodological quality and near-universal gaps in measurement error and responsiveness data. Clinicians and researchers should preferentially select instruments with established structural validity, internal consistency, and test-retest reliability verified by COSMIN methodology for their specific patient population. Full publication review is required before adopting any specific instrument recommendation into clinical or research protocols.
