Psychological Mindedness and Alexithymia Predict Symptom Reduction in Cognitive Behavior Therapy for Major Depressive Disorder

Efficacy of Intellect's self-guided anxiety and worry mobile health programme: A randomized controlled trial with an active control and a 2-week follow-up

Digital self-guided mobile health [mHealth] applications are cost-effective, accessible, and well-suited to improve mental health at scale. This randomized controlled trial [RCT] evaluated the efficacy of a recently developed mHealth programme based on cognitive-behavioral therapy [CBT] principles in improving worry and anxiety. We also examined psychological mindedness [PM] as a mediator by which app engagement is thought to improve outcomes. The Intervention group completed a 2-week "Anxiety and Worry" programme with daily CBT-informed activities, while the active waitlist-control completed a matched 2-week mHealth programme on procrastination. Participants filled out the Generalized Anxiety Disorder [GAD-7], Patient Health Questionnaire [PHQ-9], and Psychological Mindedness Scale [PMS] at baseline, post-intervention, and 2-week follow-up. App engagement was measured at post-intervention only. Contrary to prediction, the Intervention group did not perform better than the Active Control group; both groups showed significant improvements on anxiety and depressive symptoms from baseline to follow-up. From post-intervention to follow-up, only the Intervention group showed further improvements for anxiety symptoms. Higher engagement with the mHealth app predicted lower anxiety and depressive symptoms at follow-up, and this relationship was fully mediated by psychological mindedness. This study provides evidence that [a] engaging in a CBT mHealth programme can reduce anxiety and worry, and [b] Psychological mindedness is a potential pathway by which engaging with a mHealth app improves anxiety and depressive symptoms. While overall effect sizes were small, at the population level, these can make significant contributions to public mental health.

Efficacy of the Mental Health App Intellect to Reduce Stress: Randomized Controlled Trial With a 1-Month Follow-up

BACKGROUND

Excessive stress is a major global health concern, particularly in young adults. Short skills-focused self-guided interventions (SGIs) on smartphones are a scalable way to improve stress-coping skills at the population level.

OBJECTIVE

In this randomized controlled trial, we aimed to examine the possible efficacy of a recently developed stress-coping SGI (Intellect) in improving psychological distress, relative to an active control group and 2 potential moderators of this predicted relationship (ie, psychological mindedness [PM] and coping self-efficacy [CSE]).

METHODS

University students (N=321) were randomly assigned to either an 8-day SGI on stress-coping or an active control group. Self-reported measures were obtained at baseline, after the intervention, and at the 1-month follow-up. The primary outcome was psychological stress (Psychological Stress Measure-9). Secondary outcomes were anxiety (Generalized Anxiety Disorder-7) and depressive symptoms (Patient Health Questionnaire-9). PM and CSE were assessed as potential moderators at baseline.

RESULTS

The final sample (n=264) included 188 (71.2%) female, 66 (25%) male, 7 (2.7%) nonbinary, and 3 (1.1%) others participants with a mean age of 22.5 (SD 5.41) years. The intervention group reported significantly lower perceived stress (partial eta-squared [ηp²]=0.018; P=.03) and anxiety (ηp²=0.019; P=.03) levels after intervention relative to the active control group. The effects on perceived stress levels remained statistically significant at the 1-month follow-up (ηp²=0.015; P=.05). Students with the lowest CSE and highest PM experienced the fastest decline in perceived stress levels (β=6.37, 95% Cl 2.98-9.75). Improvements in anxiety levels were not observed at 1-month follow-up. Similarly, no intervention effects were found for depression levels at postintervention and follow-up periods.

CONCLUSIONS

This study provides evidence that the Intellect stress-coping SGI is effective in reducing perceived stress and anxiety levels among university students. Mobile health apps are brief, scalable, and can make important contributions to public mental health.

Social Self-Efficacy and Internet Gaming Disorder Among Chinese Undergraduates: The Mediating Role of Alexithymia and the Moderating Role of Empathy

As an increasingly serious social problem, Internet gaming disorder (IGD) of college students may be related to their social self-efficacy. However, the relationship and its internal mechanisms underlying are still unclear. The current study tested the mediating effect of alexithymia in the association between social self-efficacy and IGD, and whether this mediating process was moderated by empathy. Social Self-Efficacy Scale (PSSE), Chinese version of Internet Game Addiction Scale (IGAS-C), Toronto Alexithymia Scale (TAS-20) and Interpersonal Response Scale (IRI-C) were adopted to examine the model on 888 Chinese college students. The results indicated that social self-efficacy was significantly negatively associate with IGD. Mediation analysis illustrated that alexithymia mediated the association between social self-efficacy and IGD. Further, moderated mediation analysis manifested that the mediated effects was stronger for lower level of empathy. The conclusions corroborate and clarify the mechanisms that alexithymia mediated the association between social self-efficacy and IGD, and the mediation effects is moderated via empathy. Besides, these findings provide available references for colleges to conduct educational activities, and at the same time provide scientific suggestions for preventing IGD among undergraduates.
