What is Reliability and construct validity of the modified Finnish version of the 9-item patient health questionnaire and its associations within the biopsychosocial framework among female health-care workers with sub-acute or recurrent low back pain about?

## Abstract ## Background Health-care workers have an increased risk for chronic low back pain (LBP) leading to reduced workability. Depression, a highly prevalent, costly and disabling condition, is commonly seen in patients with sub-acute LBP. This study investigated the psychometric properties and construct-validity of a modified 9-item Patient Health Questionnaire (PHQ-9-mFIN) in female health-care workers with sub-acute LBP. ## Methods Reliability (internal consistency, test-retest repeatability) was assessed using standard methods. Construct validity of the PHQ-9-mFIN was assessed as level of depressive symptoms (PHQ-9-mFIN: 0–4 none, 5–9 mild, ≥10 at least moderate) against the RAND 36 Health Survey, a valid measure of health-related quality of life (HRQoL). Additionally, the strength of the association between the levels of PHQ-9-mFIN and selected biopsychosocial factors was determined. ## Results The internal consistency of the PHQ-9-mFIN was high (Cronbach’s α = 0.82) and the test-retest repeatability scores (n = 64) were moderate: Pearson’s correlation was 0.73 and Intraclass Correlation Coefficient (ICC) 0.73 (95% CI: 0.58 to 0.82). Construct validity (Spearman correlat
