The validity of functional capacity evaluations (FCE) tests in patients with different cultural background is unknown. The aim of this study was to analyse construct validity of FCE tests in patients with neckpain related to whiplash-injury (WAD) with different cultural backgrounds within a workers’ compensation setting.
In a cross-sectional study, 314 participants (42% females, mean age 36.7 years, 52% non-native speakers) with WAD (Grade I and II) were referred for an interdisciplinary assessment that included FCE tests. Four FCE tests (hand grip strength, lifting waist to overhead, overhead working, and repetitive reaching) and self-reported pain, capacity, disability, and psychological distress were measured. To test construct validity, 26 hypotheses concerning FCE and gender, cultural background and FCE and concurrent variables were formulated a priori and tested with correlations.
FCE test results between language groups differed significantly in six out of eight comparisons. Three out of four gender-related hypotheses were not rejected. Correlation between FCE and pain ranged from -0.39 to 0.31; FCE and self-reported capacity from -0.42 to 0.61; FCE and disability from -0.45 to 0.34; FCE and anxiety from -0.36 to 0.27; and FCE and depression from -0.41 to 0.34. Hypotheses regarding FCE and reference measures were not rejected in 17 of 21 hypotheses. In 18 out of 20 analyses, correlations between FCE and reference measures did not differ between groups of different cultural background. In total 20 out of 25 hypotheses were not rejected.
The construct validity of FCE for testing functional capacity in patients with WAD with different cultural backgrounds and in a workers’ compensation setting was confirmed. Additional validation studies in other settings are needed for verification.
