    Cognitive Training Using A Mobile App As A Coping Tool Against COVID-19 Distress: A Crossover Randomized Controlled Trial
    (2022) Akin-Sari, Burcin; Inozu, Mujgan; Haciomeroglu, A. Bikem; Trak, Ezgi; Tufan, Damla; Doron, Guy; 35636516
    Background: The COVID-19 pandemic has been suggested to constitute a broad base stressor with severe mental health consequences. mHealth applications are accessible self-help tools that can be used to reduce psychological distress during the pandemic. This randomized controlled trial evaluated the effects of mobile-based cognitive training exercises on COVID-19 related distress and maladaptive cognitions.Methods: Following initial screening (n = 924), participants scoring 1 standard deviations above the mean of the COVID-19 Distress Scale were randomized into two groups. Participants in the immediate-app group (iApp; n = 25) started using the application at baseline (T0) for 12 days (from T0 to T1). Participants in the delayed-app group (dApp; n = 22) started using the mobile application at T1 (crossover) and used it for the following 12 days (T1 to T2).Results: Intention to treat analyses indicated that the iApp group exhibited lower COVID-19 distress, lower depression, fewer intolerance of uncertainty and obsessive beliefs than the dApp group at T1. In addition, using the app for 12 consecutive days was associated with large effect-size reductions (Cohen's d ranging from 0.81 to 2.35) in COVID-19 distress and related maladaptive cognitions in the iApp group (from T0 to T1) and the dApp group (from T1 to T2). Moreover, these reductions were maintained at the follow-up. Limitations: This study was a crossover trial with a relatively limited sample size and mainly female participants. Conclusion: Our findings underscore the usefulness of brief, low-intensity, portable interventions in alleviating the negative effects of the pandemic on mental health.

    The Investigation of Transdiagnostic Role of Obsessive Beliefs: Comparison of Clinical Groups Diagnosed with Obsessive Compulsive Disorder, Anxiety Disorders and Depression with University Students
    (2022) INOZU, Mujgan; KESER, Emrah; EREL, Sema; AKIN SARI, Burcin; HACIOMEROGLU, A. Bikem; OZMENLER, Kamil Nahit; 35343578
    Objective: The present study aimed to investigate whether the dysfunctional obsessive beliefs are specific to obsessive-compulsive disorder (OCD) using three different clinical groups including OCD, depression, and anxiety and a control group of university students. Method: The participants of the study comprised three patient groups with OCD (n=53), major depressive disorder (MDD, n=67), anxiety disorders (AD, n=73), and a group of university students (n=477). The short version of the Obsessive Belief Questionnaire (OBQ-20) was used to measure obsessive beliefs. The Semi-Structured Clinical Interviews for DSM-IV-TR (SCID-I), the Obsessive-Compulsive Inventory Revised Form, the Beck Depression Inventory, and the State-Trait Anxiety Inventory-Trait Form were used to assess the severity of the symptoms. Results: The scores of the three patient groups were significantly higher on the OBQ-20 as compared to the university students. It is noteworthy that the OBQ-20 scores did not significantly differ between the three patient groups except on the 'importance of thought' (ICT) subscale showing significantly higher scores in the group with OCD in comparison to the patients with depression and anxiety disorders. Conclusion: The results suggest that obsessive beliefs may have a transdiagnostic mechanism with a possible role in the etiology and maintenance of a broad range of different psychopathologies, except in relation to the 'importance and control' of thoughts. Investigating the common processes underlying different psychopathologies is important for the etiological explanation and future treatment of the disorders.
