Affectivity as mediator of the relation between optimism and quality of life in men who have sex with men with HIV

Assessing the Determinants of Quality of Life and the Impact on HIV Prevention Measures among HIV-Negative and Status-Unknown Young Men Who Have Sex with Men: A Study in Two U.S. Metropolitan Areas

Young men who have sex with men (YMSM) in the United States (U.S.) are disproportionally burdened by HIV and experience adverse social determinants of health. Minimal research has examined quality of life (QoL) and psychosocial/behavioral determinants among HIV-negative or status-unknown YMSM. We conducted a study with YMSM from two U.S. cities to assess their QoL scores, and whether specific QoL domains (e.g., physical, psychological, social, and environment) were associated with their demographics, psychosocial determinants, behavioral risk factors, and HIV prevention measures. Black YMSM, YMSM of low socioeconomic status (below high school education, income < $20,000, and lack of health insurance), and YMSM who did not disclose their sexual orientation had the lowest QoL scores across all domains. Substance use and unprotected anal intercourse were negatively associated with men’s physical/psychosocial health. Housing/food instability and perceived stress were among the strongest predictors of lower QoL in all domains. Higher physical/psychological and environment QoL scores were associated with a higher likelihood of HIV testing and PrEP use. The identification of YMSM within these demographic, behavioral, and psychosocial sub-groups is important for targeted intervention to enhance their well-being and engagement with HIV prevention.

The Influence of Internalized Homophobia on Health-Related Quality of Life and Life Satisfaction Among Gay and Bisexual Men in China

The aim of this study was to examine the influences of internalized homophobia on Chinese gay and bisexual men's quality of life and life satisfaction. Four hundred and eighty-three participants completed the Internalized Homophobia Scale, Chinese SF-12 Health Survey Version 2, and Satisfaction With Life Scale via the Internet. Scores for quality of life in several domains and life satisfaction were significantly lower than the heterosexuals' norm scores. The present study revealed that internalized homophobia significantly negatively correlated with the mental component summary score and life satisfaction. The mental component summary score mediated the relationship between internalized homophobia and life satisfaction. Sexual orientation moderated the relationship between internalized homophobia and mental component score. Gay and bisexual men in China experience poorer quality of life and less satisfaction with life compared to heterosexuals, and internalized homophobia contributes to both.

Mediating Effect of Positive Psychological Strength and Study Skills on Examination Anxiety among Nigerian College Students

Examination plays a vital role in the present contemporary educational setting as well as serving as an indicator and yardstick to place students in relation to their examination scores after they undergo the examination. However, students at different educational levels experience examination anxiety, which can interfere with making right decisions either before or during examinations and is considered to be a phenomenon associated with low examination scores. Therefore, the present research study was aimed at determining the mediating effect of positive psychological strengths between study skills and examination anxiety among Nigerian college students. The study employed survey research on 315 Nigerian college students. The result of the path analysis shows that study skills (SSK) have a significant and direct relationship on examination anxiety. The mediation between positive psychological strength (PPS) and examination anxiety is identified as being effective and significant. Therefore, positive psychological strength (PPS) acts as an effective mediator towards examination anxiety.

Positive and Negative Affect Schedule (PANAS): Psychometric Properties and Discriminative Capacity in Several Chilean Samples

We evaluated the factor structure, reliability, and discriminative capacity of the Positive and Negative Affect Schedule (PANAS) questionnaire in four different samples: two general adult populations (N = 1,548, N = 964), one adolescent population (N = 1,044), and young people with depressive symptomatology (N = 307). Exploratory factor analyses (EFAs) were performed with subsamples from Studies 1 (n = 773) and 2 (n = 527), finding that the two- and three-factor solutions had a good fit. In a confirmatory factor analysis, the two-factor solution resulted in an adequate fit in a second set of subsamples from both studies (n = 775, n = 517). In Study 3, we found good convergent and divergent validity with adequate and significant correlations found for depression (Beck's Depression Inventory), anxiety (State-Trait Anxiety Inventory), and neuroticism and extroversion (Big Five Inventory). In Study 4, the results of an EFA performed in a subsample (n = 154) found that the two- and three-factor solutions were appropriate with the former solution being confirmed in a second subsample (n = 153). Reliability was α = .85 for positive affect and α = .87 for negative affect. The PANAS questionnaire showed adequate indicators of validity and reliability in adult and adolescent populations as well as in a sample with depressive symptoms.

Optimism and pessimism in the general population: Psychometric properties of the Life Orientation Test (LOT-R)

Background/Objective: The Life Orientation Test-Revised (LOT-R) is often used to assess dispositional optimism. The aims of this study were to test psychometric properties of the LOT-R, to provide normative scores, and to test the association between optimism and several psychological, sociodemographic, and behavioral factors. Method: A randomly selected German general population community sample with an age range of 18-80 years (N = 9,711) was surveyed. Results: The Confirmatory Factor Analysis (CFA) proved two (correlated) factors: Optimism and Pessimism. Invariance tests across gender and age groups confirmed metric invariance. There were only small gender differences in the LOT-R total score (M = 16.4 for females and M = 16.1 for males). The correlation between the subscales Optimism and Pessimism was strong for young and well educated people. Low optimism mean scores were observed for unemployed people, people with low income, smokers, and obese people. Normative scores of the LOT-R are provided. Conclusions: The study confirmed the bidimensional structure of the LOT-R and invariance across age and gender. We can recommend using this instrument for measuring dispositional optimism and pessimism in epidemiological research and clinical practice.
