Major depressive disorder aggregates within families, although the mechanisms of transfer across generations are not well understood. In light of converging biological and behavioral evidence that depressive symptoms are associated with impaired reward processing, we examined whether adolescent girls with a parental history of depression would also exhibit abnormal reward sensitivity. We performed a negative mood induction and then recorded the feedback negativity, a neural index of reward processing, while individuals completed a gambling task. High-risk adolescents reported greater sadness following the mood induction compared to low-risk adolescents. Among the high-risk group, sadness was strongly associated with a blunted feedback negativity, even after controlling for baseline mood and trait neuroticism. This suggests that high-risk adolescents are more reactive to negative stimuli, which significantly alter neural sensitivity to monetary gains and losses. The feedback negativity might be used to identify information processing abnormalities in high-risk populations prior to the onset of a major depressive episode.

The impact of gynaecological cancer and its treatments on sexual intimacy can be profound on female sexuality. However, very few registered clinical trials have addressed sexual intimacy among this cohort. This preliminary randomised control trial (RCT) and content analysis assessed the effectiveness of a brief online mindful compassion group intervention adjunct with cannabis suppositories.

This retrospective, descriptive study, conducted in 2024, analysed Virtual Care Survey (2020-2022) data of patients' self-reported reflections on use and experiences to investigate relationships between demographics, the number of chronic conditions, and virtual care use among older rural patients (≥65 years with at least one chronic condition) living in New South Wales, and their satisfaction with virtual care. Associations between categorical variables were assessed using chi-squared tests, and Kruskal-Wallis tests were used for continuous variables. Qualitative feedback was analysed thematically.

Stress is becoming more prevalent among adolescents and negatively impacts their health and development. It is, therefore, pivotal to increase our knowledge about potential (personalized) healthy stress relief strategies for adolescents. This study investigated individual personality differences (i.

Previous studies have found that passive social media use (PaSMU) tends to induce upward contrast, thereby affecting well-being. However, this perspective alone may overlook the mechanisms of other social comparison phenomena. This study analyzes the influence mechanism of PaSMU on subjective well-being (SWB) by categorizing social comparison into upward identification, upward contrast, downward identification, and downward contrast while incorporating social comparison orientation (SCO) as a moderating variable.

In response to the widespread issue of fake comments on e-commerce platforms, this study aims to analyze and propose a blockchain-based solution to incentivize authentic user feedback and reduce the prevalence of fraudulent reviews. Specifically, this paper constructs a tripartite evolutionary game model between sellers, buyers, and e-commerce platforms to study the real comment mechanism of blockchain. The strategy evolution under different incentive factors is simulated using replication dynamic equation analysis and Matlab software simulation.
