AI Article Synopsis
- Research shows a strong link between alcohol misuse and psychological symptoms like depression and anxiety in adolescents, but how personality traits influence this relationship hasn't been fully explored.
- The study collected self-reported data from 393 adolescents over 18 months, using growth models to understand how early alcohol use affects psychological symptoms and if personality traits moderate these changes.
- Findings reveal that high levels of depression can lead to increased alcohol use, and certain personality traits, like impulsivity and anxiety sensitivity, shape the relationship between alcohol consumption and mental health issues.
Article Abstract
Background: A great deal of research has emerged on the comorbidity between alcohol misuse and psychological symptoms (e.g., depression, anxiety, and antisocial behavior or conduct disorder) in adolescence. Research has also shown that personality traits underlie vulnerability to alcohol use and psychological symptoms, but how personality moderates this association has not been comprehensively examined. The goals of this study are to clarify (i) whether early alcohol use effects the rate of change of psychological symptoms and vice versa, (ii) whether initial levels and rate of change in both domains vary according to individual differences in personality traits, and (iii) whether personality moderates the relationship between alcohol use and psychological symptoms.
Methods: Self-reported alcohol use, depression, anxiety, and antisocial behavior were collected from 393 adolescents at four separate time points across an 18-month period. Parallel growth models were used to assess the main objectives of the study. Personality traits [anxiety sensitivity (AS), hopelessness (H), impulsivity (IMP), and sensation seeking (SS)] were included as time-invariant predictors of initial levels and rates of change of each construct.
Results: The results indicated that elevated levels of depression predicted faster rates of increase in alcohol use. Personality-specific relationships were demonstrated across all models. IMP was shown to moderate the relationship between alcohol use and depression, suggesting that adolescents who showed a susceptibility to elevated levels of IMP, and heavier drinking were less likely to demonstrate a normative decline in depression. Adolescents with higher levels of AS and anxiety were more likely to show a faster rate of increase in alcohol use.
Conclusions: These results highlight the importance of examining personality traits in studying the associations between alcohol use and psychological symptoms.

Effect of psilocybin versus escitalopram on depression symptom severity in patients with moderate-to-severe major depressive disorder: observational 6-month follow-up of a phase 2, double-blind, randomised, controlled trial.

Background: Psilocybin therapy (PT) produces rapid and persistent antidepressant effects in major depressive disorder (MDD). However, the long-term effects of PT have never been compared with gold-standard treatments for MDD such as pharmacotherapy or psychotherapy alone or in combination.
Methods: This is a 6-month follow-up study of a phase 2, double-blind, randomised, controlled trial involving patients with moderate-to-severe MDD.

Dementia is a group of diseases, including Alzheimer's disease (AD), vascular dementia, Lewy body dementia, frontotemporal dementia, Parkinson's disease dementia, metabolic dementia and toxic dementia. The treatment of dementia mainly includes symptomatic treatment by controlling the primary disease and accompanying symptoms, nutritional support therapy for repairing nerve cells, psychological auxiliary treatment, and treatment that improves cognitive function through drugs. Among them, drug therapy to improve cognitive function is important.

Background: Sudden gains are large symptom improvements between consecutive therapy sessions. They have been shown to occur in randomised controlled trials of internet-delivered psychological interventions, but little is known about their occurrence when such treatments are delivered in routine clinical practice.
Objective: This study examined the occurrence of sudden gains in a therapist-guided internet-delivered Cognitive Therapy intervention for social anxiety disorder (iCT-SAD) delivered in the UK NHS talking therapies for anxiety and depression (formerly known as IAPT services).

Background: Despite the immense impact of Long COVID on public health and those affected, its aetiology remains poorly understood. Findings suggest that psychological factors such as depression contribute to symptom persistence alongside pathophysiological mechanisms, but knowledge of their relative importance is limited. This study aimed to synthesise the current evidence on psychological factors potentially associated with Long COVID and condition-relevant outcomes like quality of life.

Background: Predicting dementia early has major implications for clinical management and patient outcomes. Yet, we still lack sensitive tools for stratifying patients early, resulting in patients being undiagnosed or wrongly diagnosed. Despite rapid expansion in machine learning models for dementia prediction, limited model interpretability and generalizability impede translation to the clinic.
