This longitudinal study examined whether specific cognitive patterns during pregnancy predict postpartum obsessive-compulsive (OC) symptoms. A diverse sample of 256 women was assessed at 20 weeks of pregnancy (Time 1), 6 weeks postpartum (Time 2; n = 233), and 6 months postpartum (Time 3; n = 231). At each point, participants completed interview and/or self-report measures of OC symptoms, psychological distress, and obsessive beliefs (i.e., cognitive patterns related to OC symptoms). Postpartum OC symptoms were common, reported by 87.1 % at Time 2 and 74.5 % at Time 3. Stronger prenatal obsessive beliefs during pregnancy predicted greater postpartum OC symptom severity and higher likelihood of an OCD diagnosis at Time 3, even after controlling for baseline OC symptoms and distress. Findings highlight the clinical importance of prenatal cognitive risk factors and support cognitive-behavioral models of postpartum OCD.

Psychosexual Stages of Personality: Anal01:26

Psychosexual Stages of Personality: Anal

Sigmund Freud's theory of psychosexual development describes the anal stage as occurring between 18 months and three years of age. During this period, children derive pleasure from controlling and releasing their bowel movements. However, they quickly learn that societal expectations impose restrictions on when and where this can happen. This stage marks a critical point where children begin to develop a sense of control and mastery over their bodily functions, as well as their broader...

Psychosexual Stages of Personality: Oral

The oral stage is the initial phase of Sigmund Freud's theory of psychosexual development, occurring from birth to approximately 12 to 18 months. During this period, the infant's mouth serves as the primary source of pleasure, with actions such as sucking, chewing, biting, and drinking playing a crucial role in reducing tension. These activities are essential not only for nourishment but also for the infant's psychological and emotional satisfaction.
