This meta-analysis combined 241 effect sizes from 114 studies to test how six habitual emotion-regulation strategies relate to symptoms of anxiety, depression, eating disorders, and substance-related problems. Rumination showed the strongest (large) link with symptoms. Avoidance, problem solving, and suppression showed medium-to-large links, while reappraisal and acceptance showed smaller (small-to-medium)…
This small randomized trial tested a fully automated text-based conversational agent called Woebot as a way to deliver cognitive behavioral therapy to college-age young adults with symptoms of depression and anxiety. Over 2 weeks, the Woebot group (n=34) showed a statistically larger drop in depression scores (PHQ-9) than an information-only…
This 2001 review looked at studies on exercise, anxiety, depression, and stress. It found that short-term emotional effects of exercise are mixed, but many cross-sectional and longitudinal studies report that regular aerobic exercise training reduces anxiety and depression symptoms and may protect against the harmful effects of stress. The clearest…
This umbrella review looked at the best existing reviews and large studies to see if depression is linked to low serotonin or low serotonin activity. Across measures of serotonin in fluids, receptor and transporter studies, tryptophan depletion experiments, and large genetic studies, the evidence was mixed or absent. The authors…
This phase 3, double-blind trial tested whether continuing esketamine nasal spray plus an oral antidepressant could delay relapse in adults with treatment-resistant depression who had already improved after an initial esketamine course. Of 297 patients who entered the randomized phase, continuing esketamine reduced relapse compared with switching to placebo nasal…
A group of international mood-disorder experts reviewed the research on ketamine and esketamine for adults whose depression did not get better with usual antidepressants. They found that these drugs work differently from standard antidepressants and can lift symptoms more quickly for some people with treatment-resistant depression. However, the experts also…
This article reviews a large body of research on cognitive-behavioral therapy (CBT) for anxiety disorders. It focuses on two common CBT methods — exposure therapy and cognitive therapy — and concludes that CBT generally works for many anxiety problems. The authors also say it is hard to compare active CBT…
Repeated ketamine infusions have cumulative and sustained antidepressant effects. Reductions in depressive symptoms were maintained among responders through once-weekly infusions. These findings provide novel data on efficacious administration strategies for ketamine in patients with treatment-resistant depression. Future studies should further expand on optimizing administration to better translate the use of…
Putting feelings into words, called affect labeling, can reduce how strong emotions feel. It often does not feel like a deliberate way to control feelings. The review finds that affect labeling shows effects similar to a deliberate strategy called reappraisal across people's experience, bodily responses, brain activity, and behavior. The…
Major depressive disorder (MDD) is defined without assuming a single cause and has two main symptoms: depressed mood and loss of interest or pleasure. The paper says we should also pay more attention to fatigue, sleep problems, anxiety, thinking (cognitive) problems, and sexual problems when diagnosing and judging treatment. Some…
This lab study compared two ways people try to manage emotions: cognitive reappraisal (changing how you think about a situation) and acceptance (not judging or trying to change feelings). In two samples totaling 142 people, reappraisal led to bigger drops in negative feelings and bigger increases in positive feelings during…
The Eysenck Personality Questionnaire (EPQ) is a self-report test made by Hans J. Eysenck and Sybil B. G. Eysenck to measure four personality scales: Extraversion (E), Neuroticism (N), Psychoticism (P), and a Lie or social-desirability scale (L). It is based on Eysenck's theory that temperament has biological and genetic roots,…
