Article Synopsis
- - The study explores the relationship between body-focused repetitive behavior (BFRB) disorders, like trichotillomania and skin picking, and anxiety disorders, finding that comorbidity is common, with notable prevalence rates for various anxiety disorders.
- - A meta-analysis of 119 studies revealed that current and lifetime prevalence rates for anxiety disorders among individuals with BFRBs are significant, such as 19.2% for generalized anxiety disorder and 27.5% for any anxiety disorder.
- - Although comorbid anxiety is frequent in BFRB cases, the correlation between anxiety severity and BFRB severity is only low to moderate, indicating a complex relationship that warrants further research and consideration in clinical practice. *
In tic disorders (TD), tic expression varies across the lifespan and as a function of contextual factors. This study explored connections between tic expression and contextual triggers across life periods in 74 adults (M = 23.2) with TDs.

The present study examined pre-treatment response inhibition and cognitive flexibility as predictors of treatment outcome, change in these domains from pre-to post-treatment, and associations with TTM severity. Participants were drawn from a randomized controlled trial comparing acceptance-enhanced behavior therapy (AEBT) to psychoeducation and supportive therapy (PST) for TTM.
View Article and Find Full Text PDFBehavior therapy is a well-established and empirically supported treatment for tic disorders (TDs). However, concerns have been expressed about the negative effects of behavioral interventions, such as tic worsening, tic substitution, and excessive effort. This study explored perceived negative effects of tic management strategies in adults with TDs and predictors of these experiences.

- - Eating disorders (ED) are serious mental health issues with high relapse rates, and wearable sensors may help monitor physiological indicators like heart rate and skin temperature to create timely interventions.
- - A systematic review examined 94 studies on the physiological measures (heart rate, heart rate variability, electrodermal activity, etc.) of individuals with various eating disorders, showing differing patterns compared to healthy individuals, particularly in Anorexia nervosa and Bulimia nervosa.
- - The findings suggest the potential for using peripheral physiological indicators in ED treatment, but more extensive and diverse research is needed to better understand their implications for diagnosis and therapy.
Article Synopsis
- Acceptance-enhanced behavior therapy for trichotillomania (AEBT-TTM) shows effectiveness in symptom reduction, with results indicating sustained benefits over a 6-month follow-up period.
- In a study involving 85 adults (mostly women), both AEBT-TTM and psychoeducation/support therapy (PST) resulted in reduced symptom severity from baseline to follow-up without worsening post-treatment.
- Although AEBT-TTM initially resulted in lower symptoms, by the 6-month mark, both therapies showed similar levels of symptom severity, suggesting AEBT-TTM may be especially beneficial for those with more severe symptoms.
Day-to-day directional relationships between sleep duration and negative affect.

Article Synopsis
- The study explored the link between sleep duration and negative feelings on a day-to-day basis in adults.
- Researchers used data from two large samples and found that shorter sleep led to more negative feelings the next day, but negative feelings didn't significantly impact how long people slept the following night.
- The analysis suggested that getting between 7.5 and 10.5 hours of sleep is ideal for minimizing negative feelings, as sleep duration had a non-linear effect on emotional well-being.
Background: Generalized anxiety disorder (GAD) and major depressive disorder (MDD) often precede and predict one another. Heightened stress reactivity may be a mediation mechanism underlying the long-term connections between GAD and MDD. However, cross-sectional studies on this topic have hindered directional inferences.
View Article and Find Full Text PDFIntroduction: Major depressive disorder (MDD) and generalized anxiety disorder (GAD) co-occur at high rates, often preceding and predicting one another over long durations. Interpersonal theories propose that relationships with others may contribute to the longitudinal connections between MDD and GAD. Therefore, the current study examined the mediational effect of positive relations with others in these connections over 18 years.
View Article and Find Full Text PDFRationale: Major depressive episodes are severe mood episodes which occur both in major depressive disorder and bipolar I and II disorder. Major depressive episodes are characterized by debilitating symptoms that often persist and interfere with typical daily functioning. Various treatments exist for major depressive episodes; however, most primary pharmacologic treatments may take weeks to months to provide relief from depressive symptoms.
