A biopsychosocial model for depressive symptoms following acute coronary syndromes

An empirical study of physical activity and sports affecting mental health of university students

Physical activity (PA) and sports are extremely essential elements for physical and mental health among adolescents. Around 30% of 16 years old and above in Malaysia have mental health issues. For this purpose, 512 university students from Malaysia were surveyed through social media, with 74% response rate. Structural equation model partial least square (SEM-PLS) was used to examine the effect of PA and sports on mental health. The results revealed that both PA (b = 0.402, p < 0.001) and sports (b = 0.330, p < 0.001) significantly predict mental health among university students. The model explained 35.8% variance in mental health. The study suggests that PA and sports activity need to be promoted among university students to control prevailing mental health issues in adolescents.

African Americans, Caribbean Blacks and Depression: Which Biopsychosocial Factors Should Social Workers Focus On? Results from the National Survey of American Life (NSAL)

Research suggests that African Americans may be more likely to experience depression, especially severe depression, than other racial or ethnic groups in the United States. Overall there is scant research comparing the relationship between ethnicity and depression among the U.S. Black population. The purpose of this study is to identify the most significant biopsychosocial factors social workers can address in the prevention and treatment of depression in African American and first generations Caribbean Black clients. Data was from the National Survey of American Life (NSAL). Bivariate associations showed that respondents who reported higher self-esteem, lower hopelessness, higher sense of mastery, and lower discrimination showed lower likelihood of having Major Depressive Disorder (MDD). The logistic regression model suggested that respondents who have ever had a chronic disease were more likely to report depression than those who have not ever had a chronic disease. Caribbean Blacks were more likely to report depression compared to African Americans. Additionally, respondents who reported higher discrimination scores were more likely to report depression. This study suggests that social workers should embrace the interconnectedness and holistic approach of the biopsychosocial model in their case conceptualizations, prevention strategies, and treatment modalities.

Physical Activity and Anxiety of Chinese University Students: Mediation of Self-System

The present study examined the role of self-enhancement and self-criticism in the relationship between physical activity and anxiety. A total of 305 students from Chinese universities, ranging in age from 18 to 36, completed a questionnaire package comprising a physical activity questionnaire, a self-enhancement strategies scale, a level of self-criticism scale, and a short form of state and trait anxiety scale. Findings highlighted that physical activity had a significant negative correlation with anxiety (r = −0.31, p < 0.01), a significant positive association with self-enhancement (r = 0.43, p < 0.01), and a significant negative relationship with self-criticism (r = −0.14, p < 0.05). It was also found that anxiety was significantly predicted by self-enhancement (−0.21, p < 0.01) and self-criticism (0.44, p < 0.01). Moreover, the mediation model supports the mediation of self-enhancement and self-criticism between physical activity and anxiety in university students. The findings suggest that interventions aimed at promoting physical activity and enhancing the self-system should be worthy strategies for reducing students’ anxiety.

Effect of Antidepressant Medication Use and Social Engagement on the Level of Depressive Symptoms in Community-Dwelling, Older African Americans and Whites With Dementia

Objective: This study examines the effect of antidepressant medication use and social engagement on the level of depressive symptoms at the time of initially meeting criteria for dementia. Method: Measures of social engagement, medication use, and depressive symptoms from 402 participants with incident dementia were utilized for the study. Proportional odds models adjusted for demographics were constructed with depressive symptoms as the outcome and social network size, perceived social isolation, and antidepressant medication use as independent variables. Results: Each additional person in the social network was associated with a lower depressive symptom score, odds ratio (OR) = 0.93, 95% confidence interval (CI) = [0.90, 0.97], p ≤ .01, and each unit increase in perceived social isolation was associated with a higher depressive symptom score (OR = 4.14, 95% CI = [2.94, 5.85], p ≤ .01). No association was found between antidepressant medication use and depressive symptom score. Discussion: Depression management at the time of dementia diagnosis should probably be directed toward increasing social engagement in older adults.

Symptoms of depression and anxiety before and after myocardial infarction: The HUNT 2 and HUNT 3 study

The long-term effect of having a myocardial infarction (MI) and to what extent post-MI anxiety and depression can be attributed to pre-MI anxiety and depression are not known. Anxiety as an independent risk factor for the onset of MI is not clear and studies treating anxiety and depression as continuous variables are lacking. Baseline data in this prospective study were obtained from the Health Study of Nord-Trøndelag County (HUNT 2). Anxiety and depression were measured with the Hospital Anxiety and Depression Scale (HADS) at HUNT 2. Age, gender, waist circumference, hypertension, total cholesterol, diabetes, and years of daily smoking were included as control variables. In the sample of 28,859 participants, 770 MI were reported in the follow-up study 5-8 years later (HUNT 3). The level of depressive symptoms at HUNT 2 was a significant and independent predictor of MI at HUNT 3, while symptoms of anxiety were not. Level of anxiety and depression at HUNT 3 was best predicted by baseline anxiety and depression. Having an MI had only a marginal effect on the levels of anxiety and depressive symptoms at HUNT 3. In the MI group, time since MI was not a significant predictor of anxiety and depression.
