Abstract
INTRODUCTION
Accurate measurement of perinatal depression is vital. We aimed to 1) test whether a factor that measured positive affect (PA) bettered a transdiagnostic model of depression symptoms and 2) replicate the model in a second sample.
METHODS
We conducted secondary analyses from two samples (n's = 657 and 142) of women in treatment at perinatal psychiatric clinics. Data were derived from items from seven commonly used measures. We compared fit indices from our original factor model-one general and six specific factors derived from the Research Domain Criteria (Loss, Potential Threat, Frustrative Nonreward, and Sleep-Wakefulness) and depression literatures (Somatic and Coping)-to our novel factor model with a PA factor. The PA factor was created by recategorizing items that measured affective states with a positive valence into a new factor. Sample 1 data were split into six perinatal periods.
RESULTS
In both samples, the addition of a PA factor improved model fit. At least partial metric invariance was found between perinatal periods, with the exception of trimester 3 - postpartum period 1.
LIMITATIONS
Our measures did not operationalize PA in the same way as in the positive valence system in RDoC and we were unable to perform longitudinal analyses on our cross-validation sample.
CONCLUSIONS
Clinicians and researchers are encouraged to consider these findings as a template for understanding symptoms of depression in perinatal patients, which can be used to guide treatment planning and the development of more effective screening, prevention, and intervention tools to prevent deleterious outcomes.
