Verbal and practical intelligence in general anxiety,obsessive compulsive and major depression disorders

IntroductionPrevious researches have shown that anxiety symptoms are negatively associated with measures of intelligence. However, recent findings indicate possible positive relationships between Generalized Anxiety Disorders (GAD) and intelligence. Also, Obsessive Compulsive Disorder (OCD) is associated with a moderate degree of underperformance on cognitive tests, including deficient processing. There are inconsistent results to present the relationship between Major Depression Disorder (MDD) and IQ. The present study has three main aims. The first aim of this study is to investigate the difference between IQ in individuals with GAD, OCD and major depressive disorder, and normal group. The second purpose is to perform a comparative study between the GAD, OCD and MDD groups on verbal and non-verbal intelligence. The third aim of this study is to examine the relationships between GAD, OCD and MDD as well as their underlying cognitive processes, including worry, rumination, and post-event processing, with verbal and non-verbal intelligence.ObjectiveThe present study is performed on four groups of participants including those with GAD, OCD, MDD and Healthy Volunteer (HV) group consisting of individuals without psychiatric disorders.MethodThe number of 50 healthy volunteers as the control group, 45 patients with GAD, 20 patients with OCD and 25 patients with MDD (n = 140) were selected as the case-referent groups. The present study was a cross-sectional type and the research was performed based on the causal-comparative method. Verbal and non-verbal intelligence was measured with the Wechsler Adult Intelligence Scale-3rd edition (WAIS-III). Rumination and post-event processing were measured by PSWQ, RRS-BR, and PEPQ, respectively.ResultsThe results indicate that Verbal Intelligence and Verbal Comprehension Index in GAD patients have significant differences in comparison to the OCD, MDD and control groups. While, the value of the Working Memory Index (WMI) in the normal group is higher than the value of the same index in the GAD, OCD and MDD groups. Also, the values of the Processing Speed Index (PSI) in normal and GAD groups are higher than the OCD and MDD groups. The worry, rumination, and post-event processing in patients with GAD are positively correlated with general and verbal intelligence. But, verbal and non-verbal intelligence had a negative correlation with worry, rumination and post-event processing in healthy volunteers.ConclusionInvestigation of the possible connections between intelligence and the cognitive processes underlying emotional disorders can provide therapeutic strategies for smart individuals who are at risk for GAD.     

From elementary school to midlife: Childhood personality predicts behavior during cognitive testing over four decades later

The current study uses a prospective, longitudinal design and lifespan perspective to understand how child personality relates to directly observed adult behavior during cognitive testing. Teacher assessments of child Big Five personality in elementary school were correlated with directly observed behaviors during a videotaped cognitive test four decades later. Past work suggested Openness and Conscientiousness may relate to task-relevant academic behaviors. Childhood Openness was associated with several behaviors, even after controlling for participant’s cognitive performance. Childhood Conscientiousness was also related to behavior, but not as expected. Other Big Five ratings were not reliably related to behavior. The study examined personality stability in a unique way and suggests a further examination of how Openness in children manifests in later behavior.     

Workplace intrusions and employee strain: the interactive effects of extraversion and emotional stability

Background/objectives: Intrusions are a type of workplace interruption defined as unexpected interpersonal contact that disrupts workflow. Drawing from the Job Demands-Resources model of work stress, we examined how two personal resources – extraversion and emotional stability – influence relations among intrusions and strain outcomes.

Design/methodology: Self-reported, online questionnaire data were collected from two samples; 323 faculty and staff from a university (sample 1) and 574 full-time employees recruited from an online crowdsourcing forum (sample 2).

Results: In sample 1 extraversion was positively related to intrusions, whereas in sample 2, extraversion and emotional stability were negatively related to intrusions. There were no interactive effects of personality on relations among intrusions and strain outcomes in sample 1. In sample 2, low emotional stability strengthened relations among intrusions and work tension. Additionally, intrusions were negatively associated with stress for individuals high on emotional stability. Finally, introverts experienced less stress in response to intrusions.

Conclusion: Taking a person-situation interactionist approach, we examined personal resources that may mitigate interruption-related strain. Our findings suggest that for employees high in emotional stability, interruptions may be both less detrimental and, in some cases, beneficial. This study has practical implications for the structuring of work environments to mitigate strain and maximize person-environment fit.     

Perceived Coparenting Support and Later Relationship Status among Cohabiting Parents

Abstract

To help with the fragile nature of cohabiting parents' relationship, more understanding about their interpersonal experiences is needed to identify factors that matters for their relationship stability. We examined how cohabiting parents' perceived coparenting support from their partner was associated with their later relationship status (married/cohabiting/not together). Further, we examined the possible moderating effect of perceived coparenting support on the association between marriage plans and later relationship status. Results suggested that the associations between fathers' plans and couples' marriage entrance as well as continued cohabitation were dependent upon fathers' perceived coparenting support from mothers. Clinical and research implications are discussed.     

Effects of measurement aggregation on predicting externalizing problems from preschool behaviour

In long‐term studies of psychological development, the initial assessment of etiologically significant child behaviours is often carried out at a single point in time only. However, one‐time assessments of behaviour are likely to possess limited reliability, leading to attenuated longitudinal correlation coefficient magnitudes. How much this bias might have affected behavioural continuity estimates in longitudinal research is presently unknown. Using a data set from the Mauritius Child Health Project, we particularize the attenuating effects of single‐occasion behavioural assessments on consistency estimates of impulsive–aggressive behaviour over time. Specifically, two nursery teachers provided 15 consecutive weekly ratings of the aggressive behaviour of 99 four‐year‐old children. The same children were reassessed for the presence of externalizing behaviour problems at the ages of 8 and 10. There were substantial increases in both reliability and predictive correlation coefficient magnitudes when the preschool scores were aggregated across several weekly ratings. A further increase resulted after the two outcome assessments were combined into a composite score of school‐age externalizing symptoms. A generalized procedure, developed from the correction for attenuation formula, is introduced to describe the relation of aggregation to predictive validity in longitudinal research.
