Objectives: Engagement in a greater number and more diverse activities is associated with higher levels of well‑being. One reason may be that these activities provide opportunities for a variety of social interactions. To examine the importance of the social nature of daily activity, the current study examines the unique association between social activity variety and later depressive symptoms, after adjusting for non‑social activity variety.
Method: Using data from the Health and Retirement Study (HRS), we included 5,160 adults in a cross‑sectional analysis from 2008 and 3,081 adults in a longitudinal analysis spanning 2008 to 2012, all of whom completed questionnaires on social activity participation and depressive symptoms.
Results: Cross‑sectional findings indicated that social activity variety was related to lower severity of depressive symptoms, but not likelihood of having any depressive symptoms, after adjusting for health, sociodemographic covariates, and non‑social activity. Longitudinal results showed that participants with consistently high levels of social activity variety over four years experienced fewer depressive symptoms at follow‑up compared to those with low levels, even after adjusting for baseline depressive symptoms.
Conclusion: Findings suggest that participation in a greater variety of social activities can be a protective factor against the severity of depressive symptoms.

The novelty, saliency, and valency of ongoing experiences potently influence the firing rate of the ventral tegmental area (VTA) and the locus coeruleus (LC). Associative experience, in turn, is recorded into memory by means of hippocampal synaptic plasticity that is regulated by noradrenaline sourced from the LC, and dopamine, sourced from both the VTA and LC. Two persistent forms of synaptic plasticity, long-term potentiation (LTP), and long-term depression (LTD) support the encoding of different kinds of spatial experience.

Objective: Mental health problems are increasing worldwide, and research has shown that it can be affected by work-life conflict (WLC). The aim of the present study is to examine the association between WLC and both stress and depressive symptoms in early adulthood.
Methods: A cross-sectional and a 4-year follow-up study was conducted using register data and questionnaire data from The West Jutland Cohort Study (VestLiv), Denmark.
Background: Young adults (15-24 years old) living with HIV may experience pressure both from HIV infection and social role change problems, resulting in a series of psychological problems such as depression and anxiety. Effective psychological intervention can improve their mental health and quality of life.
Objective: The study aims to explore the effectiveness of VR-based mental intervention on young adults living with HIV.

Objective: Although increasing evidence suggests that depression/distress involves inflammatory processes, its potential sex differences and the temporal directions for this association remain elusive.
Methods: We examined the temporal association between serum inflammatory mediators and depression/distress as measured by the Center for Epidemiologic Studies Depression Scale (CES-D) and the Kessler Psychological Distress Scale (K6), in non-depressed working men and women (n = 61 and 43, respectively) by a 16-month prospective design.
Results: Fully-adjusted partial correlation analyses revealed that in men, a lower IFN-γ predicted subsequent increases in CES-D and K6 scores, while a higher TNF-α predicted increased K6 scores.
