Postpartum exuberance: Not all women in a highly positive emotional state in the postpartum period are denying depression and distress

The question addressed in this study was whether or not mothers who scored low on self-report depression scales—so-called “deniers”—were denying their symptoms and suffering from an illusion of mental health. The findings did not support the interpretation that low-scoring mothers were denying other symptoms. Rather, low-scoring mothers: 1) experienced a wide range of emotions and similar levels of positive emotions compared to mid-symptom mothers; 2) changed their reported levels of depressive symptoms over the course of the study; 3) reported a variety of symptoms at levels similar to those of mothers in the mid symptom range; and 4) were affected negatively by having a diagnosis of depression, in a manner similar to mothers in the mid and high symptom groups. Furthermore, low symptom mothers consistently reported the most positive profiles of maternal adaptation with higher levels of maternal self-esteem and a high ratio of self-reported positive to negative affect. Thus, they appeared to be experiencing a heretofore underdescribed highly positive normal postpartum state that we have labeled “postpartum exuberance.” Postpartum exuberance, as well as a compromise of affective functioning associated with any lifetime diagnosis of depression regardless of the mothers' current level of depressive symptoms, highlights the complexity of emotional reactivity during the postpartum period. © 1997 Michigan Association for Infant Mental Health     

Helping children apply their knowledge to their behavior on a dimension-switching task

To investigate why 3-year-olds have difficulty in switching sorting dimensions, children of 3 and 4 years were tested in one of four conditions on Zelazo's card sort task: standard, sleeve, label and face-up. In the standard condition, children were required to sort blue-truck and red-star cards under either a blue-star or red-truck model card, first by color or shape, and then by the other dimension. Here 3-year-olds sorted correctly until the dimension changed; they continue to sort by the initial dimension. The sleeve condition (placing the sorting cards in an envelope prior to sorting) had little effect. In the label condition, the child labeled the relevant sorting dimension on each trial. Most 3-year-olds succeeded; evidently their labeling helped them refocus their attention, overcoming ‘attentional inertia’ (the pull to continue attending to the previously relevant dimension). In the face-up condition, attentional inertia was strengthened because sorted cards were left face-up; 4-year-olds performed worse than in the standard condition. We posit that attentional inertia is the core problem for preschoolers on the card sort task.     

Treatment Effect on Recidivism for Juveniles Who Have Sexually Offended: a Multilevel Meta-Analysis

The current study investigated the effect on recidivism of treatment aimed at juveniles who have sexually offended. It also assessed the potential moderating effect of type of recidivism, and several treatment, participant and study characteristics. In total, 14 published and unpublished primary studies, making use of a comparison group and reporting on official recidivism rates, were included in a multilevel meta-analysis. This resulted in the use of 77 effect sizes, and 1726 participants. A three-level meta-analytic model was used to calculate the combined effect sizes (Cohens d) and to perform moderator analyses. Study quality was assessed with the EPHPP Quality Assessment Tool for Quantitative Studies. A moderate effect size was found (d = 0.37), indicating that the treatment groups achieved an estimated relative reduction in recidivism of 20.5% as compared to comparison groups. However, after controlling for publication bias, a significant treatment effect was no longer found. Type of recidivism did not moderate the effect of treatment, indicating that treatment groups were equally effective for all types of recidivism. Also, no moderating effects of participant or treatment characteristics were found. Regarding study characteristics, a shorter follow up time showed a trend for larger effect sizes, and the effect size calculation based on proportions yielded larger effect sizes than calculation via mean frequency of offending. Implications for future research and clinical practice are discussed.
