Emotional reasoning processes and dysphoric mood: cross-sectional and prospective relationships

Promotive factors associated with internalising symptoms amongst college students during the COVID-19 lockdown in Enugu metropolis, Nigeria

Background

The outbreak of the coronavirus disease 2019 (COVID-19) pandemic has caused a high burden of psychological distress amongst adolescents.

Aim

This study aimed to evaluate associations of personal strengths including resilience and social support with internalising symptoms amongst college students during the lockdown in the wake of the COVID-19 pandemic.

Setting

The study population included students from senior and junior college classes in public schools in Enugu metropolis, Nigeria.

Method

A school-based cross-sectional study design was employed for the study. A two-stage sampling technique was used to select 496 students (mean age = 16.5, s.d. = 1.9 years; 52.2% female) in six out of 33 public colleges in Enugu metropolis, Nigeria during the lockdown period occasioned by the COVID-19 pandemic. Validated questionnaires assessing anxiety, depression, resilience and social support were used to collect information.

Results

Most of the students reported depressive symptoms, whilst just over a third of the sample reported anxiety or both depressive and anxiety symptoms. Chi-square and logistic regression analyses revealed that being male and reporting higher levels of social support and the ability to bounce back from stress were associated with less anxiety. Being younger and reporting a moderate level of support were associated with more depressive symptoms, whilst the ability to bounce back was associated with fewer depressive symptoms.

Conclusions

Good social support and the ability to bounce back from stress were linked to lower levels of anxiety and depressive symptoms amongst college adolescents during the lockdown in the wake of the COVID-19 pandemic despite high prevalence rates.

The superior longitudinal fasciculus and its functional triple-network mechanisms in brooding

Brooding, which refers to a repetitive focus on one's distress, is associated with functional connectivity within Default-Mode, Salience, and Executive-Control networks (DMN; SN; ECN), comprising the so-called "triple-network" of attention. Individual differences in brain structure that might perseverate dysfunctional connectivity of brain networks associated with brooding are less clear, however. Using diffusion and functional Magnetic Resonance Imaging, we explored multimodal relationships between brooding severity, white-matter microstructure, and resting-state functional connectivity in depressed adults (N = 32-44), and then examined whether findings directly replicated in a demographically-similar, independent sample (N = 36-45). Among the fully-replicated results, three core findings emerged. First, brooding severity is associated with functional integration and segregation of the triple-network, particularly with a Precuneal subnetwork of the DMN. Second, microstructural asymmetry of the Superior Longitudinal Fasciculus (SLF) provides a robust structural connectivity basis for brooding and may account for over 20% of its severity (Discovery: adj. R² = 0.18; Replication: adj. R² = 0.22; MSE = 0.06, Predictive R² = 0.22). Finally, microstructure of the right SLF and auxiliary white-matter is associated with the functional connectivity correlates of brooding, both within and between components of the triple-network (Discovery: adj. R² = 0.21; Replication: adj. R² = 0.18; MSE = 0.03, Predictive R² = 0.21-0.22). By cross-validating multimodal discovery with replication, the present findings help to reproducibly unify disparate perspectives of brooding etiology. Based on that synthesis, our study reformulates brooding as a microstructural-functional connectivity neurophenotype.

Confirmatory Factor Analysis of the Nepean Dysphoria Scale in a Clinical Sample

The construct of dysphoria has been described inconsistently across a broad range of psychopathology. The term has been used to refer to an irritable state of discontent, but is also thought to incorporate anger, resentment and nonspecific symptoms associated with anxiety and depression, such as tension and unhappiness. The Nepean Dysphoria Scale has been developed to allow assessment of dysphoria, but its factor structure has not yet been investigated in clinical samples. We aimed to determine the latent structure of dysphoria as reflected by the Nepean Dysphoria Scale, using a clinical sample. Adults (N = 206) seeking treatment at a range of mental health services were administered the Nepean Dysphoria Scale. Four putative factor structures were investigated using confirmatory factor analysis: a single-factor model, a hierarchical model, a bifactor model and a four-factor model as identified in previous studies. No model fit the data except for a four-factor model when a revised 22-item version of the original 24-item scale was investigated. A four-factor structure similar to that identified in non-clinical samples was supported, albeit following the removal of two items. The Nepean Dysphoria Scale appears to have utility for the assessment of dysphoria in routine clinical settings.

Does emotional reasoning change during cognitive behavioural therapy for anxiety?

Emotional reasoning refers to the use of subjective emotions, rather than objective evidence, to form conclusions about oneself and the world. It is a key interpretative bias in cognitive models of anxiety disorders and appears to be especially evident in individuals with anxiety disorders. However, the amenability of emotional reasoning to change during treatment has not yet been investigated. We sought to determine whether emotional reasoning tendencies change during a course of routine cognitive-behavioural therapy (CBT). Emotional reasoning tendencies were assessed in 36 individuals with a primary anxiety disorder who were seeking treatment at an outpatient clinic. Changes in anxiety and depressive symptoms as well as emotional reasoning tendencies after 12 sessions of CBT were examined in 25 individuals for whom there was complete data. Emotional reasoning tendencies were evident at pretreatment assessment. Although anxiety and depressive symptoms decreased during CBT, only one of six emotional reasoning interpretative styles (pertaining to conclusions that one is incompetent) changed significantly during the course of therapy. Attrition rates were high and there was not enough information regarding the extent to which therapy specifically focused on addressing emotional reasoning tendencies. Individuals seeking treatment for anxiety disorders appear to engage in emotional reasoning, however routine individual CBT does not appear to result in changes in emotional reasoning tendencies.
