Family functioning among adolescents with bipolar disorder.

This study examined the characteristics of families of adolescents with bipolar disorder during or shortly following a period of mood exacerbation, using measures of family conflict, cohesion, adaptability, and expressed emotion (EE). Demographic, diagnostic, and family functioning data were collected from 58 families (mean age = 14.48; 33 female, 25 male) before entering a randomized trial of family focused treatment. Compared to scale scores reported by healthy adolescents and their families, cohesion and adaptability were more impaired in families with an adolescent with bipolar disorder. Levels of conflict, while higher than normative scores reported by healthy families, were not significantly different from scores gathered from distressed, clinic-referred families. Parents rated high in EE reported less cohesion and adaptability, and more conflict, than parents rated low in EE. Parents expressing greater numbers of critical comments also reported more conflict than those who expressed fewer criticisms. These EE group differences were not accounted for by concurrent adolescent symptom levels. Family adaptability, cohesion, and conflict may be important targets for family treatments administered during the postepisode phases of early onset bipolar disorder.

Sex differences in social memory tasks.

College females were superior to college males in memory for 3 tasks—one life situation and 2 names-and-faces tests. A new test, the KW Memory for Names and Faces Test, demonstrated a "same-sex recall" tendency for this sample. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Family functioning and mood disorders: A comparison between patients with major depressive disorder and bipolar I disorder.

Within a sample of patients with major depressive disorder (MDD; n = 121) and bipolar affective disorder (BPAD; n = 69), the authors examined (a) diagnostic differences in family functioning at acute episode, (b) diagnostic differences in family functioning at episode recovery, (c) within-group changes in family functioning from acute episode to recovery, and (d) whether within-group changes from acute episode to recovery varied by diagnosis. Using a multidimensional model, the authors evaluated interviewer, patient, and family ratings. Overall, patients with MDD and BPAD evidenced similar levels of family impairment at acute episode and recovery. Generally, patients in both groups experienced improvement in family functioning over time, yet mean scores at recovery continued to range from fair to poor. Although certain specific differences emerged, diagnostic groups appeared to be more similar than different in level and pattern of family functioning.

Diagnostic differences in social anhedonia: A longitudinal study of schizophrenia and major depressive disorder.

This study examined the hypothesis that, in schizophrenia, elevated trait social anhedonia (SA) is a stable individual difference, whereas in depression, increased SA is a reflection of a current clinical state that will diminish with recovery. Differences in trait Negative Affect (NA) and Positive Affect (PA) were also examined. Individuals with schizophrenia (n?=?55) and depression (n?=?34) were evaluated at baseline during hospitalization and compared with nonpsychiatric control participants (n?=?41). Participants were assessed again at a 1-year follow-up. At baseline, compared with control participants, individuals with schizophrenia and depression were both characterized by elevated SA, greater NA, and lower PA. In schizophrenic individuals, elevated SA remained stable over the follow-up. However, in recovered depressed patients, SA declined over the follow-up period. Group differences remained in NA and PA over the 1-year follow-up. These results support the view that elevated SA is enduring in schizophrenia but that elevated SA is transiently related to clinical status in depression.

Temporal discounting of rewards in patients with bipolar disorder and schizophrenia.

Patients with bipolar disorder (BD) and schizophrenia (SZ) often show decision-making deficits in everyday circumstances. A failure to appropriately weigh immediate versus future consequences of choices may contribute to these deficits. We used the delay discounting task in individuals with BD or SZ to investigate their temporal decision making. Twenty-two individuals with BD, 21 individuals with SZ, and 30 healthy individuals completed the delay discounting task along with neuropsychological measures of working memory and cognitive function. Both BD and SZ groups discounted delayed rewards more steeply than did the healthy group even after controlling for current substance use, age, gender, and employment. Hierarchical multiple regression analyses showed that discounting rate was associated with both diagnostic group and working memory or intelligence scores. In each group, working memory or intelligence scores negatively correlated with discounting rate. The results suggest that (a) both BD and SZ groups value smaller, immediate rewards more than larger, delayed rewards compared with the healthy group and (b) working memory or intelligence is related to temporal decision making in individuals with BD or SZ as well as in healthy individuals.

Predictors of relationship functioning for patients with bipolar disorder and their partners.

Previous investigations have examined family functioning, including marital functioning, as an important predictor of the course of bipolar disorder, but limited research exists identifying the factors that influence relationship functioning in patients with bipolar disorder. In the current study, 56 patients with bipolar disorder and their partners were assessed for Axis II pathology, general family functioning, and relationship distress. Patient mood symptoms and Axis II pathology variables were examined as predictors of general relationship functioning (Family Assessment Device, McMaster Clinical Rating Scale, and Dyadic Adjustment Scale) in regression models. Analyses indicated that patients' depressive symptomatology was associated with patient ratings of general family functioning and couple functioning, while patients' manic symptoms were associated with partners' ratings of the romantic relationship. Partners' total Axis II pathology, but not patients' Axis II pathology, was associated with patient and partner perception of the couple's relationship. These findings highlight the importance of mood and personality pathology to relationship functioning, and represent one of the first investigations to verify the impact of personality pathology on patients' and partners' perceptions of relationship functioning.

Modal attention asymmetry in patients with schizophrenia and bipolar disorder.

This cross-sectional study examined modal attention asymmetries in patients with schizophrenia (n?=?47) and bipolar disorder (n?=?42), as contrasted to a matched-sample comparison group of normal participants (n?=?89). A test of continuous auditory and visual attention was the primary measure. The data were analyzed from 2 experimental conditions: simple modal responses (auditory and visual) and modal switching responses (ipsimodal and cross-modal switching). In the simple modal condition, patients with schizophrenia demonstrated a visual over auditory asymmetry; patients with bipolar disorder showed no differences. In modal switching conditions, however, patients with bipolar disorder displayed a significant auditory over visual asymmetry. No main effect was detected between medications and attention functioning. Results are discussed in light of differentiating these 2 populations on the basis of modal specificity of attention functioning. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Family functioning in bipolar I disorder.

In a sample of 62 patients with Bipolar I disorder, the authors used a repeated measures longitudinal design to examine whether global family functioning was associated with the presence of a concurrent bipolar episode as well as whether global family functioning was associated with the presence of manic and depressive episodes in the following 3 months. Participants were recruited for a randomized clinical trial examining the efficacy of family treatments combined with pharmacotherapy for bipolar disorder. Global family functioning was repeatedly measured with both clinician-rated and patient-rated assessment instruments over the 28-month study period. Results indicated that mood episodes were associated with concurrent global family functioning within individuals, but global family functioning was not associated with episode status in the subsequent 3 months. The repeated measures nature of these results suggests that global family functioning and bipolar episodes may fluctuate in concert with each other but that global family functioning is not associated with subsequent change in episode status.

Sex differences in cooperation: A meta-analytic review of social dilemmas.

Although it is commonly believed that women are kinder and more cooperative than men, there is conflicting evidence for this assertion. Current theories of sex differences in social behavior suggest that it may be useful to examine in what situations men and women are likely to differ in cooperation. Here, we derive predictions from both sociocultural and evolutionary perspectives on context-specific sex differences in cooperation, and we conduct a unique meta-analytic study of 272 effect sizes—sampled across 50 years of research—on social dilemmas to examine several potential moderators. The overall average effect size is not statistically different from zero (d = –0.05), suggesting that men and women do not differ in their overall amounts of cooperation. However, the association between sex and cooperation is moderated by several key features of the social context: Male–male interactions are more cooperative than female–female interactions (d = 0.16), yet women cooperate more than men in mixed-sex interactions (d = –0.22). In repeated interactions, men are more cooperative than women. Women were more cooperative than men in larger groups and in more recent studies, but these differences disappeared after statistically controlling for several study characteristics. We discuss these results in the context of both sociocultural and evolutionary theories of sex differences, stress the need for an integrated biosocial approach, and outline directions for future research.

Performance of schizophrenia and bipolar patients on verbal and figural working memory tasks.

Working memory (WM) was studied in 82 healthy volunteers, 43 schizophrenia patients, and 81 bipolar patients. Schizophrenia patients were impaired on verbal and figural WM tasks that possessed similar test discriminating power. Bipolar patients performed similarly to healthy volunteers. A mathematical model of WM performance revealed a primary role for reduced WM span in accounting for the impaired verbal WM of schizophrenia patients and a primary role for diminished attention in accounting for impaired figural WM. Although WM impairment in schizophrenia is due neither to the general effects of severe mental illness nor to the specific type of material studied, the microarchitecture of abnormal WM in schizophrenia may depend on the stimulus material presented.

Development of social functioning in preschizophrenia children and adolescents: A systematic review.

Schizophrenia is associated with severe deficits in social functioning. Similar deficits may be present prior to psychosis onset, in childhood and adolescence. If so, then prepsychosis social deficits could provide clues to the development of pathological processes in preschizophrenia children and could potentially improve early identification of the disorder and suggest targets for intervention. Evidence is reviewed from birth cohort, case- control, and familial high-risk studies within distinct periods of development to clarify the nature, timing, and specificity of social deficits in preschizophrenia children and adolescents. The results indicate that poor social functioning does differentiate preschizophrenia children and adolescents from their peers and can be a sensitive and potentially specific predictor of schizophrenia, not just psychopathology in general. Furthermore, age (but not sex) appears to be an important moderator of the strength and specificity of the association between particular social deficits (e.g., externalizing, internalizing) and later schizophrenia. Results are discussed in the context of current developmental theories of timing and pathophysiology of schizophrenia involving hypothalamic- pituitary-adrenal dysregulation. Implications for the early identification and treatment of preschizophrenia individuals are also considered. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Parenting and social functioning of children with and without cerebral palsy.

Objective: To examine the associations between parenting dimensions and the social functioning of children with and without cerebral palsy (CP). The primary hypothesis was that controlling for cognitive ability, specific parenting dimensions would be associated with higher social functioning, including larger social networks, higher-quality friendships, and healthier social adjustment in children with and without CP. Participants: Forty-one children with cerebral palsy and 60 typically developing (TD) children, ages 6 to 12. Measures: Parenting Dimensions Inventory; Social Network Inventory for Children, Friendship Quality Questionnaire, Personality Inventory for Children-Second Edition, WISC-III Vocabulary. Results: Bivariate associations revealed that cognitive ability was associated with social functioning in both groups. In the group with CP, controlling for cognitive ability, parenting dimensions were not associated with social functioning, in contrast with findings in the TD sample. Conclusions: Findings suggest different parenting influences on the social development of children with and without CP. Theoretical and methodologic implications are discussed.

Same-sex attraction, social relationships, psychosocial functioning, and school performance in early adolescence.

The authors examined whether 13- to 15-year-old adolescents who experience feelings of same-sex attraction (SSA) differ from those without such feelings in the quality of relationships with parents, peers, and class mentors and in psychosocial functioning (health status and school performance). The authors also assessed whether differences in psychosocial functioning resulted from differences in the quality of social relationships. Data were collected from 866 Dutch high school students (mean age 13.61 years) by means of a computer-based questionnaire. Of the participants, 74 (8.5%) reported having feelings of SSA. The participants with SSA rated the quality of their relationships with their fathers and their peers lower than did those without SSA. Participants with SSA also had poorer mental health (higher levels of depression and lower levels of self-esteem) and lower school performance. A mediation analysis revealed that differences in psychosocial functioning resulted from differences in the quality of the same-sex attracted youths' social relationships, especially with fathers and peers.

Sex and anxiety differences in eyelid conditioning.

Data concerning the relationship between eyelid conditioning performance and 2 S variables, Ss' sex, and scores on the MA scale, are examined. In studies employing standard procedures, high-anxiety Ss were superior to low-anxiety Ss in 23 of 27 comparisons, and females superior to males in 18 of 19 comparisons. In contrast, the direction of the differences was split approximately equally between high- and low-anxiety Ss and between males and females in studies in which conditioning was presented within the context of masking probability-learning task.

Sex differences in the genetic and environmental influences on childhood conduct disorder and adult antisocial behavior.

Sex differences in the genetic and environmental influences on childhood conduct disorder and adult antisocial behavior were examined in a large community sample of 6,383 adult male, female, and opposite-sex twins. Retrospective reports of childhood conduct disorder (prior to 18 years of age) were obtained when participants were approximately 30 years old, and lifetime reports of adult antisocial behavior (antisocial behavior after 17 years of age) were obtained 8 years later. Results revealed that either the genetic or the shared environmental factors influencing childhood conduct disorder differed for males and females (i.e., a qualitative sex difference), but by adulthood, these sex-specific influences on antisocial behavior were no longer apparent. Further, genetic and environmental influences accounted for proportionally the same amount of variance in antisocial behavior for males and females in childhood and adulthood (i.e., there were no quantitative sex differences). Additionally, the stability of antisocial behavior from childhood to adulthood was slightly greater for males than females. Though familial factors accounted for more of the stability of antisocial behavior for males than females, genetic factors accounted for the majority of the covariation between childhood conduct disorder and adult antisocial behavior for both sexes. The genetic influences on adult antisocial behavior overlapped completely with the genetic influences on childhood conduct disorder for both males and females. Implications for future twin and molecular genetic studies are discussed. (PsycINFO Database Record (c) 2011 APA, all rights reserved)     

Sex differences in job satisfaction.

Measures of 5 separate aspects of job satisfaction gathered from 295 male workers and 163 female workers drawn from 4 different plants were analyzed with respect to the mean job satisfaction for the male and female workers. T2 analyses indicated that in 3 plants the female workers were significantly less satisfied than their male counterparts (p     

The relationship between formal thought disorder and executive functioning component processes.

In 2 studies, associations between formal thought disorder (FTD) and 2 components of executive functioning, processing of context and interference resolution, were investigated. One study, involving people with schizophrenia, examined associations between performance on processing of context (N-back) and interference resolution (interference in Steinberg probe recognition) tasks and FTD. The second study, involving nonpsychiatric participants, was an analogue study that examined the effects of simulated processing of context (performance of 1-back with distraction) and interference resolution (telling new stories about previously seen pictures) deficits on FTD in a speech production task. In both studies, processing of context deficits predicted FTD. Moreover, in both studies, the effect of processing of context deficits on FTD was especially pronounced when combined with interference resolution deficits.

Neural responses to masked fear faces: Sex differences and trauma exposure in posttraumatic stress disorder.

Although women have a greater propensity than men to develop posttraumatic stress disorder (PTSD) following trauma, sex differences in neural activations to threat have received little investigation. This study tested the prediction that trauma would heighten activity in automatic fear-processing networks to a greater extent in women than in men. Functional magnetic resonance imaging (fMRI) data were recorded in 23 participants with PTSD (13 women, 10 men), 21 trauma-exposed controls (9 women, 12 men), and 42 non-trauma-exposed controls (22 women, 20 men) while they viewed masked facial expressions of fear. Exposure to trauma was associated with enhanced brainstem activity to fear in women, regardless of the presence of PTSD, but in men, it was associated only with the development of PTSD. Men with PTSD displayed greater hippocampal activity to fear than did women. Both men and women with PTSD showed enhanced amygdala activity to fear relative to controls. The authors conclude that greater brainstem activation to threat stimuli may contribute to the greater prevalence of PTSD in women, and greater hippocampal activation in men may subserve an enhanced capacity for contextualizing fear-related stimuli.
