The Russian invasion of Ukraine is accompanied by horrific losses among civilians. This study investigates various individual (hope, optimism, resilience, post-traumatic growth, and coping strategies) and contextual predictors (experience of life under occupation, actively hostile home environment, and frequent moves) of subjective well-being among the youth living in Ukraine. A total sample of 593 students from several universities participated in the study using surveys that contained questions about sociodemographic characteristics, life satisfaction, hope, optimism, personal post-traumatic growth, resilience, and coping strategies. Data were analyzed using JAMOVI software. The level of dissatisfaction with their own lives was 34.7%; most of the respondents had a higher incidence of minimal/mild hopelessness (88.7%) and high/moderate level of optimism (60.9%). The majority of participants had moderate and high levels of post-traumatic growth (51.9% and 6.7%, respectively) and resilience (46.0% and 14.5%, respectively). Optimism, hope, resilience, post-traumatic growth, using emotional support, and life in occupation predicted life satisfaction among the study sample.
Physical and cognitive interventions are deemed the primary methods of improving cognitive functioning in healthy older adults. However, the effectiveness of these interventions is still debated. This systematic review, synthesised findings from the literature on four different types of interventions: physical activities, cognitive training, cognitive stimulation and a combined intervention. We searched six databases for each intervention category. Findings demonstrated that 65% of the studies across all intervention groups reported improvement in the experimental group following the intervention. Furthermore, memory, executive and global cognitive functions were the most reported improvements post-intervention. Additionally, participants with higher education benefited more from cognitive training (an intervention that targets a specific cognitive domain), while those with lower education gained more following cognitive stimulation (an intervention that targets general domains). Lastly, in sub-types of physical activity, cognitive stimulation and combined category, longer durations (more than 20 sessions) were associated with significant cognitive improvements. Conversely, in cognitive training, having less than 20 sessions led to significant results. Findings indicated an interaction of education and intervention duration with significant outcomes post-intervention. In conclusion, this review demonstrated the importance of intervention type, duration and education in understanding cognitive improvement post-intervention.
