Measuring grief following miscarriage: psychometric properties of the Chinese version of the Perinatal Grief Scale.

Grief following miscarriage is a complex psychological response. This study was conducted to examine the psychometric properties of the Chinese version of the Perinatal Grief Scale (PGS). A total of 280 Chinese women completed the PGS immediately following a diagnosis of miscarriage (baseline) and were reassessed at 12 months follow-up. The factor structure of the Chinese PGS was explored. The convergent validity of the PGS was established by examining its correlations with the General Health Questionnaire-12 and Beck Depression Inventory at baseline. The reliability of the Chinese PGS was satisfactory. A two-factor structure accounting for 45% of the variance was identified. The Chinese PGS was positively correlated with General Health Questionnaire-12 and Beck Depression Inventory scores. The Chinese PGS was found to be a reliable and valid tool to measure grief following miscarriage.
