Detection of depression in women of child-bearing age in non-Western cultures: a comparison of the Edinburgh Postnatal Depression Scale and the Self-Reporting Questionnaire-20 in Mongolia.

BACKGROUND: This study assesses, for the first time, the validity and internal reliability of the Edinburgh Post Natal Depression Scale (EPDS) and the WHO Self-Reporting Questionnaire 20-item version (SRQ-20) in detecting depression in Mongolian women of reproductive age. METHODS: 100 women age recruited from two psychiatric units specialising in depression (n = 55) and three community-based child immunisation clinics (n = 45) in Ulaanbataar, Mongolia, were formally psychiatrically assessed by a clinician and by administering the revised Clinical Interview Schedule (CIS-R). Each woman also completed the EPDS and SRQ-20. RESULTS: Ninety four women provided complete data and identical optimal cut-off points for both the EPDS (11.5) and SRQ-20 (8.5) were determined against both the psychiatrist's and CIS-R based diagnosis using standard validation parameters. On all parameters the SRQ-20 performed better than the EPDS. The sensitivity of the SRQ-20 in detecting depression was 93% and the specificity 97% against the psychiatrist's diagnosis. Internal reliability was satisfactory. LIMITATIONS: The use of a mixed clinical and community sample for validation, and a single psychiatrist may limit the generalisability of these results. CONCLUSIONS: The SRQ-20 performed well and better than the EPDS in detecting depression in this group of Mongolian women

Depression in Mongolian women over the first 2 months after childbirth: prevalence and risk factors.

BACKGROUND: Social, political and economic changes in Mongolia have followed post-Soviet style government policies and contributed to both increased liberalisation and reduced security in employment and family finances. This is the first study to attempt to assess the prevalence of depression in a population of Mongolian women in the post-partum period and assess risk factors, including financial position, associated with the condition. METHODS: A total of 1044 women who had delivered healthy babies in Ulaanbaatar between October and December 2002 were screened for depression using the WHO Self Reporting Questionnaire between 5 and 9 weeks post-partum. Further details on the mother, her family and social and economic circumstances were simultaneously collected. Analysis of risk factors for probable depression was undertaken using multiple logistic regression techniques. RESULTS: The prevalence of depression was 9.1% (95% CLs 7.5%-11.1%). Variables significantly and independently associated with risk of probable maternal depression included economic factors, mother being subject to physical abuse, dissatisfied with the pregnancy, concerned about her baby's behaviour, and her own health problems. LIMITATIONS: The sample was drawn from a population of mothers all of whom had healthy, full-term babies of normal birth weight. Clinical confirmation of diagnosis was not established. CONCLUSIONS: Mongolian women with young infants in Ulaanbaatar probably experience depression at rates comparable with other cultures. Factors associated with probable depression were dominated by health, relationships and financial position
