[Comparative study on the predictive factors of anxiety among Quebec university students during the pandemic (COVID-19)]

Objective In this study, we present the results of a comparative research carried out on three cohorts of university students in the context of a pandemic. Several research indicate that the anxiety level of populations has increased significantly. Method In this article, we present the results of a comparative study of three cohorts study conducted on 1674 Quebec students. Participants were recruited at three separate time points, in the summer of 2020 (cohort 1; N = 398), in the fall of 2020 (cohort 2; N = 621) and in the winter of 2021 (cohort 3; N = 655). Anxiety was measured using Beck's anxiety inventory and several sociodemographic variables were tested. Results Results from cohort 1 indicate that being younger and having a mental health diagnosis may be vulnerability factors for anxiety. For cohort 2, the interaction of gender x diagnosis x program of study had a significant effect. Age and family income were predictive of significant anxiety in cohort 3. Limitations and perspectives of the study are explored. Conclusion The study recommends that the results be considered in developing preventive and intervention programs in the post-pandemic period.

Correlates of Dampening and Savoring in Generalized Anxiety Disorder

Chronic worry and generalized anxiety disorder (GAD) symptoms are associated with infrequent savoring, and high dampening, of positive emotions. The goal of the present study was to investigate the indirect role of GAD-relevant processes, including intolerance of uncertainty (IU), fear of negative emotional contrasts, and negative beliefs about positive emotion and its regulation, in the relationship between GAD symptom severity and the tendency to engage in dampening and not savor positive emotions. Community participants (N = 233) completed questionnaires online.

In separate models, IU, fear of negative emotional contrasts, and negative beliefs about positive emotion and its regulation fully mediated the relationships between GAD symptom severity and greater dampening and lower savoring. However, controlling for depression, only IU remained a significant mediator. A post hoc latent analysis of the mediators provided support for an underlying construct that may reflect intolerance of uncomfortable states. Intolerance of uncomfortable states was found to significantly mediate the relationship between GAD symptoms and greater dampening and lower savoring. Difficulty withstanding uncertainty may be particularly relevant in understanding why people with elevated GAD symptoms engage in efforts to avoid experiencing positive emotions. Further, the findings suggest that there may be a common factor underlying a variety of GAD-associated constructs reflecting a broad intolerance of uncomfortable inner states. Theoretical and clinical implications are discussed.

The Role of Intolerance of Uncertainty and Working Alliance in the Outcome of Cognitive Behavioral Therapy for Generalized Anxiety Disorder Delivered by Videoconference: Mediation Analysis

BACKGROUND

Previous meta-analyses have shown a significant relationship between working alliance and treatment outcome in general. Some studies have examined the relationship between working alliance and treatment outcome during telepsychotherapy, but to the best of our knowledge, no study has examined the mediating role of individual components of the working alliance.

OBJECTIVE

As part of a clinical trial of cognitive behavioral therapy (CBT) for generalized anxiety disorder (GAD) delivered by videoconference (VC), the aim of this study is to examine the mediating role of intolerance of uncertainty on the relationship between the components of the working alliance and treatment outcome.

METHODS

A sample of 46 adults with primary GAD received 15 sessions of CBT for GAD delivered over VC. Participants completed the measure of working alliance immediately after the fifth therapy session. The degree of change in intolerance of uncertainty (a key psychological process) was assessed from pre- to posttreatment. Treatment outcome was assessed via changes in GAD symptoms from pretreatment to the 6-month follow-up.

RESULTS

The results revealed that the therapeutic bond did not predict treatment outcome (r=-0.23; P=.12). However, agreement on therapeutic goals and tasks did predict treatment outcome (r=-0.42; P=.004 and r=-0.37; P=.01, respectively). In addition, the relationship between consensus on therapeutic tasks and treatment outcome was completely mediated by changes in intolerance of uncertainty (unstandardized β=-0.03; r2=0.12), whereas consensus relative to treatment goals had a direct impact on treatment outcome.

CONCLUSIONS

These results provide a better understanding of the differential role of the components of the working alliance in telepsychotherapy as a facilitative factor for changes in key cognitive processes, leading to therapeutic change.
