Central Executive Network and Executive Function in Patients With Alzheimer's Disease and Healthy Individuals: Meta-Analysis of Structural and Functional MRI.

Objective: The neural architecture of executive function is of interest given its utility as a transdiagnostic predictor of adaptive functioning. However, a gap exists in the meta-analytic literature assessing this relationship in neuropsychiatric populations, concordance between structural and functional architecture, and the relationship with neuropsychological assessment of executive function. Given the importance of the central executive network (CEN) in Alzheimer's disease, this population may be useful in understanding this relationship in Alzheimer's disease pathology.

Climate change anxiety and mental health: Environmental activism as buffer.

A growing body of research has documented the phenomenon of climate change anxiety (CCA), defined broadly as negative cognitive, emotional, and behavioral responses associated with concerns about climate change. A recently validated scale of CCA indicated two subscales: cognitive emotional impairment and functional impairment (Clayton & Karazsia, 2020). However, there are few empirical studies on CCA to date and little evidence regarding whether CCA is associated with psychiatric symptoms, including symptoms of Major Depressive Disorder (MDD) and Generalized Anxiety Disorder (GAD), and whether engaging in individual and collective action to address climate change could buffer such relationships.

The central executive network and executive function in healthy and persons with schizophrenia groups: a meta-analysis of structural and functional MRI.

This meta-analysis evaluated the extent to which executive function can be understood with structural and functional magnetic resonance imaging. Studies included structural in schizophrenia (k = 8; n = 241) and healthy controls (k = 12; n = 1660), and functional in schizophrenia (k = 4; n = 104) and healthy controls (k = 12; n = 712). Results revealed a positive association in the brain behavior relationship when pooled across schizophrenia and control samples for structural (pr = 0.

Depression with Mixed Features in Adolescent Psychiatric Patients.

Depression with mixed features is poorly understood, especially in pediatric samples. This study compares symptoms and correlates of depressed adolescent inpatients with mixed features to inpatients with bipolar disorder and major depression. 407 adolescents were administered diagnostic interviews and self-reports, and 262 were categorized as Depression with Mixed Features (MXD; n = 38), Consensus Bipolar (CB; n = 79), or Depression Only (DO; n = 145).

Examining Associations of Sexual Attraction and Attitudes on Women's Disordered Eating Behavior.

Objective: We aimed to expand the scant research on disordered eating in women identifying same-sex sexual attractions.

Method: We used multiple linear regressions to explore potential mechanisms driving disordered eating--both explicit and implicit weight bias and heterosexism--in a cross-sectional, online-recruited community sample of women (N = 437). Participants endorsed a range of sexual attractions from exclusively opposite-sex (21.

Cognitive estimation and its assessment.

Purpose: We evaluated the internal consistency and construct and criterion validity of a 10-item revision of the Cognitive Estimation Task (CET-R) developed by Shallice and Evans to assess problem-solving hypothesis generation.

Method: The CET-R was administered to 216 healthy adults from the Aging, Brain Imaging, and Cognition study and 57 adult outpatients with schizophrenia.

Results: Exploratory and confirmatory factor analysis (EFA and CFA) of the healthy sample revealed that seven of the 10 CET-R items constitute a more internally consistent scale (CET-R-7).

Negative cognitions as a moderator in the relationship between PTSD and substance use in a psychiatrically hospitalized adolescent sample.

Adolescents exposed to trauma are more likely to engage in alcohol and marijuana use compared to their nontrauma-exposed counterparts; however, little is known about factors that may moderate these associations. This study examined the potential moderating effect of cognitions relevant to exposure to trauma (i.e.

Associations of Mothers' Friendship Quality with Adolescents' Friendship Quality and Emotional Adjustment.

Little research has examined the association of parents' friendships with adolescent's well-being, perhaps because the association was considered too distal. However, developmental theories suggest that contexts in which parents, but not their children, are situated may be related to child development (Bronfenbrenner, 1979; 1986). The current work examined associations between the quality of mothers' own friendships and their adolescent children's friendship quality and emotional adjustment.

Perceptions of friendship among youth with distressed friends.

This cross-sectional study examined the relationship between a friend's level of internalizing distress and the focal child's perceptions of friendship amongst 5th, 8th, and 11th grade youth. Participants completed the Youth Self-Report to assess internalizing distress and measures assessing perceptions of friendship quality, social support, and self-disclosure within reciprocal, same-sex friendship dyads. Results indicated that youth with friends experiencing low levels of internalizing distress reported poorer friendship quality and decreased levels of social support and self-disclosure within the friendship compared to youth with friends experiencing average or high internalizing distress.

Irritability and elation in a large bipolar youth sample: relative symptom severity and clinical outcomes over 4 years.

Objective: To assess whether relative severity of irritability symptoms versus elation symptoms in mania is stable and predicts subsequent illness course in youth with DSM-IV bipolar I or II disorder or operationally defined bipolar disorder not otherwise specified.

Method: Investigators used the Kiddie Schedule for Affective Disorders and Schizophrenia for School-Age Children to assess the most severe lifetime manic episode in bipolar youth aged 7-17 years who were recruited from 2000 to 2006 as part of the Course and Outcomes of Bipolar Youth prospective cohort study (N = 361), conducted at university-affiliated mental health clinics. Subjects with at least 4 years of follow-up (N = 309) were categorized as irritable-only (n = 30), elated-only (n = 42), or both irritable and elated (n = 237) at baseline.

Manic symptoms in youth with bipolar disorder: factor analysis by age of symptom onset and current age.

Background: Factor analysis has been used to identify potential clinical subtypes of mania in pediatric bipolar disorder. Results vary in the number of factors retained. The present study used a formal diagnostic instrument to examine how symptoms of mania in young people are expressed, depending on age of symptom onset and current age.

Discrepancies between youth and mothers' perceptions of their mother-child relationship quality and self-disclosure: implications for youth- and mother-reported youth adjustment.

Recently, researchers have devoted greater attention to understanding how disagreement between mothers and their children regarding parent-child relationship quality and functioning impacts youth adjustment. While some view discrepancies as indices of developmentally appropriate individuation, discrepancies regarding family functioning also have been found to predict problematic youth functioning. This study examined the effects of mother-child discrepancies for mother-child relationship qualities and youth self-disclosure on youth- and mother-reported youth internalizing and externalizing adjustment.

How girls and boys expect disclosure about problems will make them feel: implications for friendships.

Although girls disclose to friends about problems more than boys, little is known about processes underlying this sex difference. Four studies (Ns = 526, 567, 769, 154) tested whether middle childhood to mid-adolescent girls and boys (ranging from 8 to 17 years old) differ in how they expect that talking about problems would make them feel. Girls endorsed positive expectations (e.
