This study was designed to identify predictors of lower versus higher willingness to use pre-exposure prophylaxis (PrEP) to reduce HIV among men who have sex with men (MSM) in China. Participants were 570 MSM who completed self-report measures of willingness to use HIV PrEP, beliefs about HIV, psychosocial factors, sexual experiences and sociodemographic(More)
In this experiment, sensitivity to female facial attractiveness was examined by comparing event-related potentials (ERPs) in response to attractive and unattractive female faces within a study-test paradigm. Fourteen heterosexual participants (age range 18-24 years, mean age 21.67 years) were required to judge 84 attractive and 84 unattractive face images(More)
Previous event-related potential (ERP) and brain imaging studies have suggested observer responses to others’ pain are modulated by various bottom-up and top-down factors, including emotional primes. However, the temporal dynamics underlying the impact of emotional primes on responses to others’ pain remains poorly understood. In the present study, we(More)
The author conducted this cross-sectional study to assess the extent to which employed, unemployed, and student samples of young adults could be differentiated on the basis of psychosocial experiences. Forty-four employed, 41 unemployed, and 42 student volunteers completed measures of emotional distress, time structure, financial strain, skill use, task(More)
UNLABELLED Two experiments assessed how interpersonal transactions influence responses to cold pressor pain in women versus men. In Experiment 1, 91 young adults (57 women, 34 men) were randomly assigned to either a no transaction (NT) condition in which they coped alone with the cold pressor test or a transaction opportunity (TO) condition in which they(More)
UNLABELLED A meta-analysis was performed to evaluate overall strengths of relation between self-efficacy (SE) and functioning (pain severity, functional impairment, affective distress) in chronic pain samples, as well as potential moderating effects of sociodemographic characteristics and methodologic factors on these associations. In sum, 86 samples (N =(More)
Perceived stress reflects the extent to which situations are appraised as stressful at a given point in one's life. Past brain imaging studies have examined activation patterns underlying the stress response, yet focal differences in brain structures related to perceived stress are not well understood, especially when considering gray matter (GM) and white(More)
OBJECTIVE Numerous studies have documented rates of chronic pain in developed western nations; however, little is known about its prevalence or correlates in rapidly developing countries, where much of the world's population lives. This study was designed to assess the prevalence of chronic pain among adults in Chongqing, China and the correlates of(More)
The nature of interactions between observing pain in others (other-pain) and subjective pain perception (self-pain) has been debated. To test whether other-pain and self-pain primes increase or decrease responsiveness to complementary self-pain or other-pain targets, two ERP studies were conducted. In Study 1, twenty participants (10 women, 10 men) were(More)
