The WHO Adult ADHD Self-Report Scale (ASRS) has 18 questions about recent ADHD symptoms, and a shorter six-question screener was tested against blind clinical diagnoses in 154 people from the US National Comorbidity Survey Replication. Each ASRS item was linked to the clinical rating, but agreement varied a lot across…
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…
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,…
The authors combined results from 42 studies of people in prison to estimate how common ADHD is in those groups. Using formal diagnostic interviews, the overall ADHD rate was about 25.5%. Reported rates were higher when studies used screening tools or when adults recalled childhood ADHD. The review found much…
This review looks at studies in humans and animals that link anxiety and stress with poorer cognitive flexibility — the ability to change strategies when rules or goals change. It describes evidence that the prefrontal cortex (PFC) is central to flexible behavior, that anxiety or PFC disruptions are associated with…
This paper pooled results from 19 randomized trials with 1,173 adults to see if meditation and yoga change PTSD symptoms. Overall, these mind–body practices were linked to a small-to-medium reduction in PTSD symptoms (effect size = −0.39). The authors found no big differences by type of practice, who was studied,…
In a natural, open-label study at a microdosing event, researchers tested people before and while they expected the effects of a psychedelic truffle microdose. They found better performance on a task that measures convergent thinking and on a task that measures divergent thinking. A short test of fluid intelligence did…
This meta-analysis combined 48 experimental studies with 7,679 people to test how seeing “upward” comparison targets on social media (people who seem better off) affects users’ feelings about themselves. Overall, exposure to upward comparisons produced a small but statistically significant negative effect on self-evaluations and emotions (g = −0.24, p…
These two studies tested whether men and women differ in jealousy when real infidelity happened rather than in made-up stories. One study used a paper survey with students and the other used a web survey with non-students. Both studies found that men reported more jealousy about the sexual parts of…
This small, exploratory study gave people with moderate to severe major depressive disorder placebo first (19 people) and then a single dose of psilocybin (0.3 mg/kg) to 15 people four weeks later, with all dosing embedded in therapy based on Acceptance and Commitment Therapy (ACT). After the psilocybin session, measures…
Researchers used online surveys to compare three U.S. adult groups—college students (mean age 21), younger adults from Amazon’s Mechanical Turk (mean age 31), and older adults recruited through the Institute for Challenging Disorganization (mean age 54). They found that behavioral procrastination (putting off actions) explained more of the differences in…
