BACKGROUND: Perinatal psychiatric disturbances afflict a significant number of women sometimes with tragic consequence. Yet, the range and characteristics of these disturbances are poorly understood. The goals of this research were to characterize a broader range of postpartum psychiatric symptoms and to identify their inherent structure using exploratory factor analysis (EFA).
METHODS: An Internet-based survey with 142 Likert-type questions, covering nine dimensions of postpartum mental health was constructed and posted on women's health websites. Data collected from 215 respondents was analyzed in three steps: (1) inter-item correlations were used to reduce the total number of variables by eliminating items that provided redundant information; (2) an EFA using a principal components extraction and VARIMAX rotation was performed and factors loading with Eigenvalues >1.0 were retained; (3) internal consistency was measured with Cronbach's alpha.
RESULTS: The 10 factors retained accounted for 58% of the variance and included: mental status (28%), psychoticism/morbid thoughts (6%), generalized anxiety (6%), panic (3%), guilt/self-criticism (3%), compulsive behavior (3%), hyper-vigilance (2%), contentment (2%), negative body-image (2%), and manic behavior (2%). There was strong (>0.8) internal consistency in all but the mania factor (0.6).
LIMITATIONS: The study was retrospective and respondent demographics were homogeneous.
CONCLUSION: Postpartum psychiatric disturbances are not limited to depressive symptoms. In the current study, cognitive difficulties, psychotic-morbid thoughts and anxiety symptoms accounted for the preponderance of variance while depressive symptoms did not form a cohesive factor and accounted for minimal variance. These results suggest postpartum screening tools should assess a broader array of symptoms.
