Adaptation of the Edinburgh Postnatal Depression Scale in the Indonesian Version: Self-reported Anxiety and Depression Symptoms in Pregnant WomenAdaptation of the Edinburgh Postnatal Depression Scale in the Indonesian Version: Self-reported Anxiety and Depression Symptoms in Pregnant Women

Abstract

BACKGROUND: Anxiety and depression disorders in pregnant women are often not identified so that early treatment is not optimal. Indonesia already has comprehensive integrated antenatal care, including services for pregnant women with mental disorders, but until now Indonesia does not yet have a standardized instrument that is valid and suitable as a screening tool to assess symptoms of anxiety and depression in pregnant women. The Edinburgh Postnatal Depression Scale (EPDS) is a screening instrument with high sensitivity and specificity, has been translated into Indonesian, but until now, the Indonesian version of the EPDS instrument has not been evaluated for validity and reliability in the population of pregnant women.
 AIM: this study aimed to adapt the Indonesian version of the EPDS instrument, including testing the validity and reliability of the instrument when used on pregnant women in Indonesia.
 METHODS: This research is a cross sectional study. The number of pregnant women who participated were 125 samples. Data were collected randomly, and the assessment of symptoms of anxiety and depression was self-reported via online. Content validity was assessed with a content validity index from 5 experts, construct validation was analyzed by Explanatory Factor Analysis and Confirmatory Factor Analysis and Convergent Validity. The reliability of the EPDS instrument was assessed by construct reliability and Cronbach's Alpha.
 RESULTS: Content validity index shows expert agreement with a value of .98. The Indonesian version of the EPDS shows assessing three factors, namely: Depression (5 items), Anxiety (3 items), and Anhedonia (2 items). The reliability of the Indonesian version of the EPDS instrument is good with Cronbach's Alpha .80 and the internal reliability of the 10 items (Cronbach's Alpha .767-.812).
 CONCLUSION: The Indonesian version of the EPDS instrument is valid and reliable to be used to assess symptoms of anxiety and depression in pregnant women in antenatal care in Indonesia.
