Abstract

AIM: This study aims at identifying a group/groups of women during the perinatal period with thought of self-harm, which is reflected by preceded suicidal ideation, by cluster analysis and clarify their psychological correlates.

METHODS: A secondary analysis was conducted using the data of the longitudinal study investigated in 18 obstetric clinics between 2011 and 2012 in Kumamoto Prefecture (Japan). Self-administered questionnaires including demographic data, the Edinburgh Postnatal Depression Scale (EPDS), the Temperament and Character Inventory, and the Postnatal Bonding Questionnaire were distributed during the third trimester of pregnancy (Wave 1), at five days (Wave 2), and one month postpartum (Wave 3).

RESULTS: The cluster analysis using the data of participants who answered all observational points discrete the participants into two groups: Cluster 1 (normal, n = 201), and Cluster 2 (thought of self-harm, n = 42). Low Self-directedness, low cooperativeness, higher anxiety, depression, and lack of affection and anger and rejection towards the baby were associated with the Cluster 2.

CONCLUSIONS: The finding that low self-directedness and low co-operativeness were related to Cluster 2 group suggested that immature personality traits may work as a predisposing factor mediating between anxiety, depression and a thought of self-harm.
