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.

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
