Relations Between Optimism-Pessimism and Loneliness in Sexually Minoritized Men: The Moderating Role of Chronicity-Based Discrimination.

Loneliness has reached epidemic proportions, affecting nearly one-in-two adults in the United States and is particularly potent in sexually minoritized men (SMM). Individual differences in optimism and pessimism may exert protective or maladaptive effects for the impact of discrimination on loneliness. This study investigated interrelationships between optimism/pessimism, discrimination, and loneliness within a sample of sexual minoritized men (SMM). Self-report data from 103 SMM were used from a six-month study from August 2020 to February 2022 in South Florida. A novel chronicity-based coding approach was used to determine whether associations of optimism/pessimism and loneliness vary based on different frequencies of exposure to discrimination. Hierarchical multivariable regression models were conducted to examine associations of optimism-pessimism and the moderating effect of chronicity-based discrimination on loneliness. SMM reporting higher pessimism and lower optimism reported greater levels of loneliness and exposure to discrimination, and chronicity-based discrimination was negatively associated with optimism, and positively associated with pessimism. Associations of optimism, but not pessimism, with loneliness were moderated by discrimination. Among the sample, optimism had a protective effect on loneliness for those experiencing moderate exposure to discrimination. Future research should consider the longitudinal impact of optimism/pessimism and discrimination on loneliness among SMM. [ABSTRACT FROM AUTHOR]
