Using natural spline models to explore the trajectories of empirically derived domains of premenstrual symptoms.

Premenstrual symptoms are distressing and impairing for individuals and costly to society. These symptoms are heterogeneous within and across people, dimensional, and dynamic. While some efforts have been made to understand the trajectories of premenstrual symptoms, two major gaps in the literature remain.

The severity and role of somatic depressive symptoms in psychological networks in a longitudinal sample of peripartum women.

The inclusion of somatic symptoms in assessing peripartum depression (PPD), which encompasses depression during pregnancy and the postpartum period, has remained controversial, as there is substantial overlap between somatic depression symptoms and normal features of pregnancy/postpartum. This study examined whether trajectories differed by PPD symptom subscale and whether PPD symptom networks changed as a function of the peripartum phase. 418 women with a history of neuropsychiatric illness participated in a longitudinal observational study, completing symptom questionnaires assessing affective, cognitive, and somatic symptoms throughout pregnancy and the first year postpartum.

Impact of age at onset on the phenomenology of depression in treatment-seeking adults in the STAR*D trial.

Background: - Adolescence is characterized by biological, emotional, and behavioral changes. The onset of depression during this vulnerable time may confer specific risks. This study examined whether symptoms of depression were associated with age at onset (AAO), and whether AAO impacted depression symptom networks in adulthood.
