Abstract
BACKGROUND: Depression is a prevalent and disabling condition associated with spinal cord injury. Such associated negative factor warrants the use of valid and reliable psychological assessment tools among this group. One of the available assessment means is the Patient Health Questionnaire-9, a short screening measure which evaluates depression status.
OBJECTIVE: Our aim is to test the psychometric properties of the Arabic version of the Patient Health Questionnaire-9 including validity and reliability among Lebanese individuals with spinal cord injury.
METHODS: This is a cross-sectional study conducted between January and June 2018, including 51 spinal cord injury participants. A questionnaire and assessment measures were administered to the subjects. The internal consistency, test-retest reliability and the factor structure of the Patient Health Questionnaire-9 were evaluated in addition to the convergent validity that was established by comparing the scale's total score with the scores of the Hamilton Depression Rating Scale.
RESULTS: Exploratory factor analysis revealed three factors accounting for 66.2% of the total variance. The scale demonstrated good internal consistency (Cronbach's alpha = 0.71) and test-retest reliability (Intraclass correlation coefficient = 0.88). Significant correlation was found between the Patient Health Questionnaire-9 and the Hamilton Depression Rating Scale (r = 0.71) suggesting good convergent validity.
CONCLUSION: Our findings suggest that the Patient Health Questionnaire-9 has good psychometric properties and is a valid and reliable measure of depression among the Lebanese individuals with spinal cord injury.
