A study using twin data suggests an association between adverse childhood experiences and poor mental health in adulthood. Targeted interventions may be associated with reduced risks of future psychopathology.
Research published by the American Psychological Association found that individuals with a history of depression spend more time processing negative information than positive information, putting them at risk for relapse. This bias towards negative thinking may hinder effective treatment and prevention strategies.
This study found that housing insecurity during childhood is associated with anxiety and depression symptoms later in life, including depression in adulthood. Social policies supporting secure housing may be a crucial prevention strategy for these mental health issues.
A study published by the American Psychological Association found that teen girls who experience greater interpersonal stress and have difficulty solving interpersonal problems are at a higher risk of suicidal behavior. The research suggests that problem-solving deficits under distress may contribute to this link.

The September issues of American Psychiatric Association journals focus on combining molecular and neuroimaging measures to understand psychopathology and inform new treatment development. Featured research includes studies on early childhood psychotic experiences and schizophrenia imaging signatures.
Mothers with personality disorder symptoms have a higher likelihood of insecure attachment with their adolescents, who are more likely to experience depression, anxiety, and substance use problems. Maternal recalled experiences with caregivers also play a mediating role in this relationship.
Researchers developed a single factor, 'p', combining different measures of psychiatric outcomes, which predicts patient prognosis and need for extra support. A high 'p' value is linked to adverse outcomes, such as suicide risk, criminality, or drug abuse.
The Hierarchical Taxonomy of Psychopathology (HiTOP) proposes viewing mental health as a spectrum, rather than categorizing it. This system simplifies diagnosis by recognizing that most patients have co-occurring disorders and classifying psychopathology at multiple levels of hierarchy.
A new diagnostic model, Hierarchical Taxonomy of Psychopathology (HiTOP), has been proposed to address fundamental flaws in the current DSM-5 model. HiTOP allows for a continuous, dimensional assessment of psychopathology, enabling more personalized treatment and recognition of significant problems.
Children with childhood psychiatric problems face higher risks of adverse outcomes in adulthood, including health, legal, and social issues. Even subthreshold symptoms can increase the risk of adult problems, highlighting the need for early intervention to reduce distress and promote optimal outcomes.
A new study finds that support from friends generally influences the effects of peer victimization on maladjustment, differing depending on the form of victimization and relationship with peers. Teenagers who suffered relational victimization experienced lower feelings of depression with more supportive friendships.
Researchers at Binghamton University found that individuals who sleep for shorter periods and go to bed later experience more repetitive negative thoughts. The study suggests that improving sleep timing may be an effective intervention for reducing symptoms of internalizing disorders.
A study published in Cognitive Therapy and Research found that individuals who sleep for shorter periods and go to bed later experience more repetitive negative thoughts. This association suggests that prioritizing regular sleep schedules may help mitigate anxiety symptoms.
A study found that younger gamblers experience fewer health problems and lower debt compared to middle-aged and older adults. Early intervention during the onset of pathological gambling is crucial for effective treatment planning.
A new study finds that depressed individuals perform better than non-depressed peers in sequential decision tasks, approximating an optimal strategy more closely. This discovery provides evidence that clinical depression may carry some benefits, which could help uncover its evolutionary roots and open avenues for treatment.
A three-year study found that withdrawn children showed increasing levels of sadness and depressive feelings over time. In contrast, children with friends were less likely to report depressed feelings, suggesting that friendship can be a protective factor against depression in this population.
