RESUMEN

Background: No randomized controlled trials have involved established HIV-diagnosed men who have sex with men (MSM) diagnosed for more than 6 months into the assisted partner service (aPS). We compared voluntary aPS involving community-based organizations (CBOs) and HIV self-testing (aPSST) with regular partner service (rPS) in HIV-diagnosed MSM irrespective of diagnosis time. Methods: In this unblinded, multicentre trial, we enrolled HIV-diagnosed MSM irrespective of diagnosis time in three cities in northern China. Index patients were randomly assigned to aPSST or rPS. Index patients in the aPSST group were additionally provided a comprehensive intervention package including HIV self-testing and CBO-based aPS compared with rPS group. The primary outcome was the number of index patients whose any sexual partner tested for HIV during the 6-month study. Completion of HIV testing was defined as sexual partners taking a clinic-based HIV test or HIV self-testing. Safety was assessed preliminary at the end of the 6-month follow-up. This study has been registered at chictr.org.cn (ChiCTR2000038784). Findings: From March to December 2021, 325 of HIV-diagnosed MSM were enrolled (90⋅2% were established HIV-diagnosed MSM) and randomly assigned to receive aPSST (n = 167) or rPS (n = 158). At 6 months, 110 (65⋅9%) index patients in the aPSST group had at least one sexual partner tested for HIV compared with 50 (31⋅6%) in the rPS group (hazard ratio 2⋅86; 95% confidence interval 2⋅03-4⋅03; p < 0⋅001). No significant difference was observed in effects of aPSST on HIV testing promotion between established and newly HIV-diagnosed MSM. Self-reported harms were infrequently observed in both groups (approximately 2⋅0%). Interpretation: Among HIV-diagnosed MSM regardless of diagnosis time, voluntary aPS involving CBOs and HIV self-testing was effective and safe for promoting partner HIV testing.

RESUMEN

BACKGROUND: The current study examined the influence of positive "basic" emotions on executive function; there is limited evidence about the influence of positive "self-conscious"emotions, such as pride, on executive functions processes. METHODS: Pride is a status-related self-conscious emotion and the present research explored the influence of pride on the subcomponents of executive function, using three experiments that adopted the digit size-parity switching, N-back, and dual choice oddball paradigms. RESULTS: The behavioral results suggested that cognitive load and behavior inhibition effects in the pride emotion were significantly higher than the neutral emotion. The ERP results showed that the pride emotion elicited smaller P3 difference wave for the switching task and dual choice oddball task. In the N-back task, the pride emotion elicited larger N1 amplitude and smaller P2 difference wave compared to the neutral emotion. A comparison among results from the three experiments indicated that pride emotion restrains all subcomponents of executive function, though with different manifestations of the impact. CONCLUSION: Experiencing positive emotions is typically viewed as desirable and adaptive in educational settings; however, pride as a unique positive emotion may damage people's cognitive performance, indicating that we need to be cautious when performing cognitive operations in a pride mood.

RESUMEN

This study uses simple tasks to induce self-conscious emotions and event-related potentials to investigate the effects of pride, neutral, and shame emotions on cognitive flexibility. The behavior results revealed that the switching tasks had a longer reaction time and a lower accuracy rate than the repetitive tasks. Furthermore, the reaction time was longer, and the accuracy rate was lower for individuals in the shame and pride emotions group than the neutral group. ERP results revealed that the switching task induced a larger P3 wave amplitude than the repetitive task. In addition, the P3 difference wave for pride and shame emotions was significantly smaller than that of neutral emotions. However, there were no significant differences in N2 wave. These findings imply that pride and shame may inhibit conversion ability and consistently affect cognitive flexibility. This consistency may be manifested in late decision-making tasks. Our finds provide a theoretical basis for management of students' pride and shame.

RESUMEN

In order to explore the relationship between parent-child attachment, negative emotion, emotional coping style, and self-injury behavior, 662 junior high school students in four junior middle schools in China's Yunnan Province were investigated using a parent-child attachment questionnaire, adolescent negative emotion questionnaire, emotional coping style scale, and adolescent self-injury behavior scale. As a result, two mediate models were created to explain how parent-child attachment affects self-injury behavior. Negative emotion and emotional coping style play serial mediating roles in mother-child and father-child attachment models, respectively. The results show that negative emotion mediates between self-injury behavior and both father-child and mother-child attachment, while emotional coping style only functions between father-child attachment and self-injury behavior. By means of bootstrap analysis, negative emotion and emotional coping style have serial mediating roles concerning the impact of parent-child attachment on self-injury behavior. By comparison, the father-child and mother-child attachment have different mediating models: the former relies on emotional coping style, while the latter is associated with emotional experiences. This implies that parent-child attachment has different mechanisms in triggering self-injury behavior, which is in line with the hypothesis of attachment specificity.
