Researchers gave the new Strengths and Difficulties Questionnaire (SDQ) and the older Rutter questionnaires to parents and teachers of 403 children from dental and psychiatric clinics. SDQ scores were highly correlated with Rutter scores, and parent-teacher agreement was similar or sometimes better for the SDQ. Both tools were about equally…
This 1992 review describes the five-factor model, which groups personality into five basic traits: Extraversion, Agreeableness, Conscientiousness, Neuroticism, and Openness to Experience. The authors summarize research using natural-language adjectives and personality questionnaires that supports the model’s broad coverage of personality and its usefulness across different observers and cultures. They review…
The study introduced the Autism-Spectrum Quotient (AQ), a short self-test that gives a score from 0 to 50 to measure autistic traits in adults with normal intelligence. The researchers tested four groups (58 adults with Asperger/high-functioning autism; 174 random controls; 840 Cambridge students; and 16 math Olympiad winners) and found…
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 study reviewed surveys and used global models to measure how the COVID-19 pandemic changed rates of major depressive disorder and anxiety disorders in 2020. It found that places with higher COVID-19 infection rates and bigger drops in movement had larger increases in these disorders. The authors estimate about 53.2…
Researchers have studied burnout for several decades. They have made tests and theories and used studies from many countries. Most work has looked at human service jobs, especially health care. Research on psychiatrists shows similar causes and results as other fields. But psychiatry also faces some unique stresses, such as…
This paper is a meta-analysis of more than 300 studies in humans that looked at links between psychological stress and measures of the immune system. It found that very short, acute stressors (minutes) were tied to increases in some natural (innate) immune measures and decreases in some specific (adaptive) immune…
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…
This 2012 paper reviewed meta-analyses on cognitive behavioral therapy (CBT). The authors found 269 meta-analytic studies and examined a representative sample of 106 reviews across many problems. They reported the strongest support for CBT for anxiety disorders, somatoform disorders, bulimia, anger control problems, and general stress. The paper concluded the…
This paper reviews research on procrastination and runs a meta-analysis of 691 correlations. It finds that some personality traits (neuroticism, rebelliousness, sensation seeking) have only weak links to procrastination. Strong and consistent predictors include task aversiveness, task delay, low self-efficacy, impulsiveness, and low conscientiousness (including poor self-control, distractibility, poor organization,…
This U.S. study used a nationally representative household survey of 3,199 adults aged 18–44, plus clinical follow-up interviews, to measure adult ADHD. Researchers estimated that 4.4% of adults had current ADHD. Adult ADHD was more common in men, people who were previously married, those who were unemployed, and non-Hispanic white…
This fact sheet reports that people with eating disorders have higher death rates than the general population. Death rates are highest for anorexia nervosa (AN). Bulimia nervosa (BN) and eating disorder not otherwise specified (EDNOS) have similar death rates. The sheet says older age at assessment was linked to higher…
