Alpha oscillatory activity is causally linked to working memory retention.

Although previous studies have reported correlations between alpha oscillations and the "retention" subprocess of working memory (WM), causal evidence has been limited in human neuroscience due to the lack of delicate modulation of human brain oscillations. Conventional transcranial alternating current stimulation (tACS) is not suitable for demonstrating the causal evidence for parietal alpha oscillations in WM retention because of its inability to modulate brain oscillations within a short period (i.e., the retention subprocess). Here, we developed an online phase-corrected tACS system capable of precisely correcting for the phase differences between tACS and concurrent endogenous oscillations. This system permits the modulation of brain oscillations at the target stimulation frequency within a short stimulation period and is here applied to empirically demonstrate that parietal alpha oscillations causally relate to WM retention. Our experimental design included both in-phase and anti-phase alpha-tACS applied to participants during the retention subprocess of a modified Sternberg paradigm. Compared to in-phase alpha-tACS, anti-phase alpha-tACS decreased both WM performance and alpha activity. These findings strongly support a causal link between alpha oscillations and WM retention and illustrate the broad application prospects of phase-corrected tACS.

'Surviving and thriving': intersectional stigma and resilience of dual minority identities among Chinese gay and bisexual men living with HIV.

Intersectionality has facilitated an understanding of the complexities of the adversities and challenges faced by individuals with multiple disadvantaged identities, including gay and bisexual men living with HIV. This study used deficiency- and empowerment-based perspectives together with an intersectionality lens to examine the intersections between sexuality minority and HIV-related stigma and resilience, as well as their compound effects on Chinese gay and bisexual men living with HIV. We conducted in-depth interviews with 21 gay and bisexual men living with HIV in Shenzhen, identifying two overarching themes and six subthemes in the provided accounts via thematic analysis. The theme of 'Interplay between Minority Identities' comprised aggravating effects and alleviating effects at the intrapersonal, interpersonal, community and structural levels. The theme of 'Compound Impact of Intersecting Identities' was contributed to by the subthemes 'the pressure to continue family lineage', 'persistent health concerns', 'financial concerns', and 'heightened psychological distress and resilience'. Integrating deficiency and empowerment perspectives, our findings highlight the importance of addressing intersectional stigma and identifying resilience resources to empower Chinese gay and bisexual men living with HIV to thrive amidst compounded adversities. Findings have implications for future intersectional research and intervention practice, especially in fostering resilience within the context of intersectional stigma.

Common Dyadic Coping Mediates the Associations Between We-Disease Appraisal and Relationship Satisfaction and Quality of Life in HIV Serodiscordant Couples: The Common Fate Mediation Model.

BACKGROUND: Since HIV has evolved into a lifelong but manageable condition, improving the quality of life (QoL) of persons living with HIV (PLWHs) has become increasingly important. Living with HIV is life-altering and poses substantial challenges for both PLWHs and their partners, so identifying how HIV serodiscordant couples cope with HIV together is crucial. Here, Bodenmann's Systemic Transaction Model highlights common dyadic coping (CDC), which refers to both partners working together to alleviate the negative effects of stress. PURPOSE: We examined the mediating role of CDC in linking we-disease appraisal with relationship satisfaction and QoL. METHODS: We recruited a convenience sample of 231 HIV serodiscordant couples via local grassroots organizations between June and October 2022. Participants completed measures of we-disease appraisal, CDC, relationship satisfaction, and QoL. We examined the mediation effect of CDC on the association between we-disease appraisal and outcomes using the common fate mediation model. RESULTS: The mean age of PLWHs was 32.18 years (standard deviation = 8.61 years), and that of their partners was 32.55 years (standard deviation = 9.24 years). The average time since HIV diagnosis was 4.18 years. Most couples were same-sex male couples. We found that CDC mediated the effect of we-disease appraisal on relationship satisfaction. Moreover, CDC significantly mediated the effect of we-disease appraisal on the QoL of PLWHs and their partners. CONCLUSIONS: Our findings highlight the importance of CDC in dyadic illness management among Chinese HIV serodiscordant couples.

Numerous studies have shown that HIV serodiscordant couples may face HIV-related stress as a unit. Yet, it is not clear how the appraisal of HIV as a shared illness (i.e., we-disease appraisal) may influence relationship satisfaction and both partners' quality of life (QoL) via common dyadic coping (CDC) behaviors (e.g., collaboration). In this study, we collected data from 231 HIV serodiscordant couples. Participants completed reports of how they appraise HIV as a we-disease, their CDC behaviors, and their relationship satisfaction and QoL. We found that we-disease appraisal was positively associated with CDC, which in turn was positively associated with relationship satisfaction and both partners' QoL. Future couple-based interventions should incorporate psycho-educational components to raise awareness about we-disease appraisal, as well as skill-building components to encourage the use of CDC in clinical settings.

Do Couple-Based Interventions Show Larger Effects in Promoting HIV Preventive Behaviors than Individualized Interventions in Couples? A Systematic Review and Meta-analysis of 11 Randomized Controlled Trials.

This systematic review and meta-analysis aims to compare the effects of couple-based prevention interventions against individual-level interventions on HIV prevention in randomized controlled trials (RCTs), identify potential moderators, and assess study quality. Eleven RCTs were included, comprising 3933 couples in the intervention group and 7125 individuals in the individual control group, predominantly in heterosexual couples from the USA and Africa. Couple-based interventions had a more significant effect in promoting condom use and HIV testing. Education levels of high school or above, residence in low- and middle-income countries, and intervention design incorporating HIV counseling and testing were associated with higher odds of condom use. The quality assessment analysis identified methodological and theoretical heterogeneity factors. Evidence of couple-based HIV prevention RCTs among men who have sex with men, injecting drug users, sex workers, and transgender women warrant further investigation. Recommendations are made to improve the quality and replicability of future intervention studies.

RESUMEN: Esta revista sistemática y metanálisis tiene por objeto comparar los efectos de las intervenciones de prevención basadas en pareja con las a nivel individual en la prevención del VIH en ensayos controlados aleatorios (ECA), identificar posibles moderadores y evaluar la calidad de los estudios. Se incluyeron once ECA, que comprendían 3.933 parejas en el grupo de intervención y 7.125 personas en el grupo de control individual, la mayoría de las cuales eran heterosexuales de EE.UU. y de África. Las intervenciones basadas en pareja son más eficaces para promover el uso de preservativos y pruebas del VIH. Los niveles de educación secundaria o superior, los países de ingresos bajos y medianos, y los diseños de intervención que incluyen pruebas y asesoramiento sobre el VIH se relacionan con más uso de preservativos. El análisis de evaluación de la calidad ha identificado factores de heterogeneidad metodológica y teórica. Las pruebas de ECA basadas en pareja para la prevención del VIH en hombres que tienen sexo con hombres, consumidores de drogas inyectables, trabajadoras sexuales y mujeres transgénero necesitan más investigación. Se hacen recomendaciones para mejorar la calidad y replicabilidad de futuros estudios de intervención.

Communal or Autonomous? Coping Experiences of Chinese Serodiscordant Male Couples to HIV Care: A Dyadic Qualitative Analysis.

Limited empirical evidence exists on the interpersonal challenges faced by Chinese serodiscordant male couples in HIV care. This study aimed to explore their coping experiences in HIV care by applying the communal coping process theoretical framework. A dyadic qualitative study using face-to-face interviews with 20 serodiscordant male couples (n = 40) was conducted between July and September 2021 in two Chinese metropolitan areas through purposive sampling. Eligibility included one partner living with HIV and the other being HIV-negative, both aged 18 or older, born male, gay or bisexual, and in a relationship together for at least 3 months. A hybrid deductive-inductive approach integrated with dyadic interview analysis and framework method was used for data analysis. We identified three themes in the coping process in HIV care: (1) coping as an autonomous process, (2) coping as a dissonant process, and (3) coping as a contextualized communal process. Concerning autonomous coping, most couples adopted either disengaged avoidance or mutual noninvolvement as negative coping strategies. We also identified potential risk factors for dissonant coping, which are a partner living with internalized HIV stigma and the couple's asymmetric relationship goals. Our results indicate the communal coping process of HIV care is contextual, and our expansion of the communal coping theory sheds light on how serodiscordant male couples cope with stressors connected to HIV care. Our findings provide theoretical insights for the development of dyadic interventions based on health psychology for Chinese serodiscordant male couples to engage in HIV care.

Family resilience of patients requiring long-term care: A meta-synthesis of qualitative studies.

BACKGROUND: Long-term care of patients with chronic illnesses is an important global public health issue, compromising the well-being of family members and the family functioning. Previous studies have examined the interactive experiences and processes of various systems in the families coping with long-term care stress; however, these studies have not been systematically reviewed and integrated. AIMS: This review aimed to synthesise the existing qualitative evidence on the experiences and processes of family resilience operate in families providing long-term care for patients with chronic illnesses and to provide suggestions for the development of interventions in future studies. MATERIALS & METHODS: We searched databases including PubMed, CINAHL, EMBASE, Web of Science, ProQuest and CNKI from their inception to March 2022. We used the JBI Critical Appraisal Tool for qualitative studies to evaluate the quality of the included studies was evaluated according to. We followed The Enhancing Transparency in Reporting the Synthesis of Qualitative Research (ENTREQ) statement. The results were integrated using the thematic and content analysis method. RESULTS: Fourteen studies from eight countries covering 11 diseases reported on the experiences and coping processes of long-term care families. Based on McCubbin's Resiliency Model of Family Stress, Adjustment and Adaptation (FAAR), five analytical themes were synthesised: stressors (risk factors), family belief system, internal family coping strategies, external support and resilient adaptation indicators; the relationships between themes and subthemes were illustrated. DISCUSSION: This review synthesized qualitative evidence on the experiences and processes of family resilience operate in families providing long-term care. The results of this study found that the cognition and belief of family members regarding dilemmas have a two-way effect and act on the adaptation process of family members. In family adaptation, spirituality, hope, internal and external support are extremely important. In 14 studies, caregivers were from different countries with intercultural differences, but due to less reports on this content, it is difficult to compare the differences or impact that culture or ethnicity may have. CONCLUSIONS: Family resilience plays an important role in coping with stressors associated with the long-term care of a loved one through family belief systems, internal support systems and external support systems. The development of family resilience-based interventions for long-term care families should consider the family as a whole and further construct a multidisciplinary, multilevel and multi-type social support network to enhance family resilience.

Adversity coping capability and its associations with mental health and family wellbeing amid the COVID-19 pandemic in Hong Kong.

BACKGROUND: Adversity coping capability (ACC) is important amid the COVID-19 pandemic. We examined the associations of ACC as measured by our one-item ACC scale (ACC-1) with mental health, family well-being and validity of ACC-1 in Hong Kong. METHODS: A cross-sectional survey was conducted on Hong Kong Chinese adults aged ≥ 18 years by landline, mobile phone, and online survey from February to March 2021, when the fourth wave of COVID-19 was under control. ACC-1 consisted of the question: "How do you rate your capability to cope with adversities?" with higher scores (0-10) indicating stronger ACC. The associations of ACC with socioeconomic characteristics, resilience, mental health, and family wellbeing were examined by linear regression coefficients (ßs). Data were weighted by sex, age, and education of the general population. RESULTS: Of 7441 respondents, after weighing, 52.2% were female and 79.1% were aged 18 to 64 years. ACC-1 showed good construct validity, with higher ACC being associated with higher levels of resilience (adjusted ß = 0.29), personal happiness (0.55), family happiness (0.42), family wellbeing (0.41), and family communication quality (0.41), and lower levels of depressive symptoms (-0.30), anxiety (-0.30), loneliness (-0.15); incremental validity with additional contributions of ACC to mental health and family wellbeing; and known-group validity with older age and favorable socioeconomic characteristics showing higher ACC (all P < 0.02). Females (mean ± standard deviation: 6.04 ± 1.82 vs 6.15 ± 1.96 [male]) and unemployed respondents (5.30 ± 1.99 vs 6.11 ± 2.03 [in paid employment]) had lower ACC (all P ≤ 0.02). CONCLUSIONS: We have first shown that stronger ACC was associated with better mental health and family wellbeing, and the results support ACC-1 as a simple and valid measure of ACC.

Stressful life events and children's socioemotional difficulties: Conditional indirect effects of resilience and executive function.

Although the association between life stress and children's socioemotional difficulties has been widely documented, few studies have adopted a cognitive-based resilience framework studying preadolescent psychosocial adjustment. This study examined whether the stress-difficulties associations are mediated by resilience and moderated by executive function (EF). A sample of 144 typically developing Chinese children (aged 10-12 years) completed measures assessing stressful life events, socioemotional difficulties, resilience, and computer-based EF (including working memory [WM] capacity and WM updating, inhibitory control, and cognitive flexibility). The results showed that stressful life events were positively associated with socioemotional difficulties through the mediating effect of diminished resilience. The direct and indirect effects of stressful life events on socioemotional difficulties varied across individual differences in EF. Specifically, compared with low to medium levels, high-level WM capacity and WM updating moderated the association between stressful life events and socioemotional difficulties. Cognitive flexibility moderated both direct and indirect effects, showing that for children with low to medium levels of cognitive flexibility, life stress was positively associated with socioemotional difficulties via the role of lower resilience; however, for those with high levels of cognitive flexibility, the direct and indirect effects were not significant. Inhibitory control showed significant direct associations with resilience and socioemotional difficulties but failed to be a moderator. The characteristics of the low-stress sample might limit the generalizability of this study. Nevertheless, our findings provide a rationale for integrating a cognitive-based resilience process and the multifaceted structure of EF to understand and promote preadolescents' positive adaptation.

Dyadic Effects of Fluid Mindset on Psychological Growth in Immigrant Mothers and Their Children: Indirect Effect of Resilience.

Immigration research has recently investigated positive adaptation outcomes such as psychological growth. This study tested actor and partner effects between fluid mindset and psychological growth, mediated by resilience, in 200 migrant mother-child dyads from Mainland China to Hong Kong. Mothers' fluid mindset had significant actor and partner effects on their own and their children's psychological growth, whereas children's fluid mindset showed an actor effect. For mothers and children, fluid mindset had significant actor indirect effects on psychological growth via resilience. Mothers' fluid mindset had a significant partner indirect effect on children's psychological growth via children's resilience. The findings have implications for enhancing immigrants' psychological growth by strengthening fluid mindset and considering mothers and children as the intervention unit in resilience programs.

En las investigaciones sobre la inmigración se han analizado recientemente los resultados de la adaptación positiva, como el crecimiento psicológico. En este estudio se evaluaron los efectos del actor y la pareja entre la mentalidad flexible y el crecimiento psicológico, mediados por la resiliencia, en 200 díadas madre e hijo de emigrantes de China continental a Hong Kong. La mentalidad flexible de las madres tuvo efectos significativos del actor y la pareja en su propio crecimiento psicológico y el de sus hijos, mientras que la mentalidad flexible de los hijos demostró un efecto del actor. Para las madres y los hijos, la mentalidad flexible tuvo efectos indirectos significativos del actor en el crecimiento psicológico mediante la resiliencia. La mentalidad flexible de las madres tuvo un efecto indirecto de la pareja en el crecimiento psicológico de los hijos mediante la resiliencia de los hijos. Los resultados tienen consecuencias para mejorar el crecimiento psicológico de los inmigrantes mediante el fortalecimiento de la mentalidad flexible y la consideración de las madres y los hijos como unidad de intervención en los programas de resiliencia.

Mediation Effect of Suicide-Related Social Media Use Behaviors on the Association Between Suicidal Ideation and Suicide Attempt: Cross-Sectional Questionnaire Study.

BACKGROUND: A limited number of studies have examined the differences in suicide-related social media use behaviors between suicide ideators and suicide attempters or have sought to elucidate how these social media usage behaviors contributed to the transition from suicidal ideation to suicide attempt. OBJECTIVE: Suicide attempts can be acquired through suicide-related social media use behaviors. This study aimed to propose 3 suicide-related social media use behaviors (ie, attending to suicide information, commenting on or reposting suicide information, or talking about suicide) based on social cognitive theory, which proposes that successive processes governing behavior transition include attentional, retention, production, and motivational processes. METHODS: We aimed to examine the mediating role of suicide-related social media use behaviors in Chinese social media users with suicidal risks. A sample of 569 Chinese social media users with suicidal ideation completed measures on suicidal ideation, suicide attempt, and suicide-related social media use behaviors. RESULTS: The results demonstrated that suicide attempters showed a significantly higher level of suicidal ideation (t563.64=5.04; P<.001; two-tailed) and more suicide-related social media use behaviors, which included attending to suicide information (t567=1.94; P=.05; two-tailed), commenting on or reposting suicide information (t567=2.12; P=.03; two-tailed), or talking about suicide (t542.22=5.12; P<.001; two-tailed). Suicidal ideation also affected suicide attempts through the mediational chains. CONCLUSIONS: Our findings thus support the social cognitive theory, and there are implications for population-based suicide prevention that can be achieved by identifying behavioral signals.

Proactive Suicide Prevention Online (PSPO): Machine Identification and Crisis Management for Chinese Social Media Users With Suicidal Thoughts and Behaviors.

BACKGROUND: Suicide is a great public health challenge. Two hundred million people attempt suicide in China annually. Existing suicide prevention programs require the help-seeking initiative of suicidal individuals, but many of them have a low motivation to seek the required help. We propose that a proactive and targeted suicide prevention strategy can prompt more people with suicidal thoughts and behaviors to seek help. OBJECTIVE: The goal of the research was to test the feasibility and acceptability of Proactive Suicide Prevention Online (PSPO), a new approach based on social media that combines proactive identification of suicide-prone individuals with specialized crisis management. METHODS: We first located a microblog group online. Their comments on a suicide note were analyzed by experts to provide a training set for the machine learning models for suicide identification. The best-performing model was used to automatically identify posts that suggested suicidal thoughts and behaviors. Next, a microblog direct message containing crisis management information, including measures that covered suicide-related issues, depression, help-seeking behavior and an acceptability test, was sent to users who had been identified by the model to be at risk of suicide. For those who replied to the message, trained counselors provided tailored crisis management. The Simplified Chinese Linguistic Inquiry and Word Count was also used to analyze the users' psycholinguistic texts in 1-month time slots prior to and postconsultation. RESULTS: A total of 27,007 comments made in April 2017 were analyzed. Among these, 2786 (10.32%) were classified as indicative of suicidal thoughts and behaviors. The performance of the detection model was good, with high precision (.86), recall (.78), F-measure (.86), and accuracy (.88). Between July 3, 2017, and July 3, 2018, we sent out a total of 24,727 direct messages to 12,486 social media users, and 5542 (44.39%) responded. Over one-third of the users who were contacted completed the questionnaires included in the direct message. Of the valid responses, 89.73% (1259/1403) reported suicidal ideation, but more than half (725/1403, 51.67%) reported that they had not sought help. The 9-Item Patient Health Questionnaire (PHQ-9) mean score was 17.40 (SD 5.98). More than two-thirds of the participants (968/1403, 69.00%) thought the PSPO approach was acceptable. Moreover, 2321 users replied to the direct message. In a comparison of the frequency of word usage in their microblog posts 1-month before and after the consultation, we found that the frequency of death-oriented words significantly declined while the frequency of future-oriented words significantly increased. CONCLUSIONS: The PSPO model is suitable for identifying populations that are at risk of suicide. When followed up with proactive crisis management, it may be a useful supplement to existing prevention programs because it has the potential to increase the accessibility of antisuicide information to people with suicidal thoughts and behaviors but a low motivation to seek help.

Stress and psychosomatic symptoms in Chinese adults with sleep complaints: mediation effect of self-compassion.

Although stress has been widely acknowledged to link to psychosomatic dysfunctioning, the underlying mechanism that transmits the impact is not adequately investigated. This study examined self-compassion as a potential mediator that may explain the pathway from stress to depressive and somatic symptoms. Data in the present study were drawn from a baseline survey of 998 Chinese participants who enrolled in an intervention study on sleep disturbance in Hong Kong. Participants completed measures of perceived stress, self-compassion, depressive symptoms, and somatic symptoms. The results showed that stress was associated with depressive symptoms (r = .79, p < .01) and somatic symptoms (r = .47, p < .01). The path analyses showed that low levels of self-compassion mediated the association between stress and psychosomatic symptoms. Our findings provide insight into the pathway how stress affects psychosomatic symptoms. The intervention programs for stress management to improve psychological and physical functioning are recommended to consider self-compassion as a promising component in practice.

Why do oncologists hide the truth? Disclosure of cancer diagnoses to patients in China: A multisource assessment using mixed methods.

OBJECTIVE: In the United States and most European countries, cancer diagnoses are disclosed to patients. In China, however, the trend toward full disclosure has progressed slowly. The present study aimed to explore attitudes toward truth-telling practice among physicians, patients, patients' family members, and the general population, and reasons for nondisclosure. METHODS: We administered a short survey to 212 physicians, 143 patients with cancer, 413 family members of patients with cancer, and 1415 members of the general population. A MANOVA was performed to examine group differences in attitudes toward cancer disclosure. In addition, we interviewed 20 oncologists. Interview data were analyzed using NVivo10. After the interview, we administered another short survey to 143 patients with cancer. RESULTS: Quantitative data indicated that physicians were the least, and patients the most, in favor of disclosure. Qualitative data among physicians and follow-up surveys among cancer patients revealed 5 reasons for the concealment of cancer diagnoses by physicians, including lack of awareness of patients' right to knowledge, cultural influences, insufficient medical resources and training, families' financial concerns, and the need to protect doctors from violence. CONCLUSION: There is a discrepancy between the needs of patients and those in medical practice. These results deepen our understanding regarding the reasons for oncologists' attitudes toward nondisclosure.

Close relationships, individual resilience resources, and well-being among people living with HIV/AIDS in rural China.

The systems framework of resilience has suggested that resilient factors external to or within the individual and their interactions can contribute to positive adjustment in at-risk populations. However, the interplays of resilience resources at different levels have seldom been investigated in health psychology, particularly in people living with HIV/AIDS (PLWHA). This study aimed to examine the mediating role of individual resilience resources in the associations between marital and family relationships and well-being in PLWHA. A sample of 160 Chinese PLWHA were interviewed to complete measures on marital relationship, family relationship, individual resilience resources, and general, physical, and mental well-being. Results showed that better marital relationship and family relationship were associated with higher levels of individual resilience resources and well-being indicators. Mediation analysis with path analysis showed significant mediating effects of individual resilience resources between marital and family relationships and general, physical, and mental well-being. By highlighting marital and family relationships as external resources of resilience and their roles in increasing individual resilience factors which thereby contribute to the well-being of PLWHA, our findings support the systems framework of resilience. There are implications for resilience enhancement interventions with the aim of improving PLWHA's well-being by including interpersonal strategies of strengthening the protective role of marital and family relationships, which will in turn facilitate the resilience process.

Couple identity and well-being in Chinese HIV serodiscordant couples: resilience under the risk of stigma.

Resilience literature has suggested the context-specific nature of resilience while such framework has yet to be expanded to health psychology research among HIV serodiscordant couples. Conceptualizing a couple affected by chronic diseases using a "we-ness" framework rather than two separate individuals is important for stress coping of the couple. Considering this social-cognitive context of couple coping would be helpful to facilitate resilience of both the patient and the spouse. It is not clear whether couple identity serves as a protective factor for HIV serodiscordant couples and whether stigma, a prevalent contextual risk in this population, will alter the strength of such a protective effect on well-being. This longitudinal study examined the protective effect of couple identity in predicting the psychological and physical well-being of HIV discordant couples and the moderating role of stigma in such associations. A total of 160 Chinese HIV serodiscordant couples completed the baseline survey and follow-up one year later. Results showed that couple identity predicted fewer depressive symptoms at both the within- and between-couple level and better self-rated physical health at the between-couple level one year later. These protective effects were diminished when HIV stigma was high. This study highlights the importance of examining resources with consideration of contextual factors. It also calls for the sensitivity of stigma in developing a couple-based intervention for HIV serodiscordant couples.

A randomized controlled trial to enhance coping and posttraumatic growth and decrease posttraumatic stress disorder in HIV-Infected men who have sex with men in Beijing, China.

Although HIV-infected men who have sex with men (MSM) constitute a newly emerged high-risk group in China, little research outside Western countries is available on effective intervention programs to enhance their well-being. The purpose of this randomized controlled trial was to evaluate the efficacy of a group intervention program designed to improve the well-being and adaptive coping strategies of 60 HIV-infected MSM in Beijing, China, randomly assigned either to the intervention group for participation in four weekly sessions or to the control group for placement on a waiting list. They all completed measurements at pre- and postintervention. Compared with the control group, the intervention group reported significantly increased problem-focused coping strategies and levels of posttraumatic growth (PTG) as well as decreased symptoms of posttraumatic stress disorder (PTSD) at the completion of the intervention. In addition, mediation analysis showed that changes in problem-focused coping strategies mediated the intervention effect on increases in PTG; however, the mediating effect of coping strategies on the association of intervention and PTSD was not significant. This study provides empirical evidence for conducting psychological intervention to promote the well-being of HIV-infected MSM. The findings also elucidate the mechanism through which intervention improved PTG.

Dyadic associations between psychological distress and sleep disturbance among Chinese patients with cancer and their spouses.

BACKGROUND: Patients with cancer and their spouses usually both suffer, but the dyadic effects have not been thoroughly investigated. This study examined the dyadic effects of psychological distress on sleep disturbance in Chinese couples affected by cancer. METHODS: Patients with cancer and their spouses (N = 135) participated in this study. The Hospital Anxiety and Depression Scale and Pittsburgh Sleep Quality Index were used to measure anxiety, depression, and sleep disturbance. RESULTS: There were significant patient-spouse associations on anxiety (r = 0.48, P < .01), depression (r = 0.55, P < .01), and sleep disturbance (r = 0.30, P < .01). Analyses using the actor-partner interdependence model showed that anxiety had significant actor effects, rather than partner effects, on sleep disturbance in both patients and their spouses, but depression had both actor and partner effects. In addition to providing evidence for the concordance in distress and sleep disturbance in patients with cancer and their spouses, the findings indicate a mutual influence of depression on sleep disturbance among the couples. CONCLUSIONS: Clinicians and health care providers are suggested to integrate depression management as a component of sleep therapies and involve both patients and their spouses in treatment programs.

Impacts of making sense of adversity on depression, posttraumatic stress disorder, and posttraumatic growth among a sample of mainly newly diagnosed HIV-positive Chinese young homosexual men: the mediating role of resilience.

The experience of HIV, as a life-transforming event, might produce both negative and positive outcomes. Guided by the stress appraisal model, the present study investigated the hypothesized pathways in predicting symptomatology and posttraumatic growth (PTG) in a sample of Chinese male patients with HIV (PHIV) who were mainly newly diagnosed, young, and homosexual. In this cross-sectional study, 141 Chinese male PHIV (87.2% of them were homosexual) completed measures of making negative/positive sense of adversity, resilience, depression, posttraumatic stress disorder (PTSD), and PTG. The path analysis results showed that making negative sense of adversity was associated with depression and PTSD, partially mediated by low levels of resilience, whereas making positive sense of adversity was associated with PTG, partially mediated by resilience. The results suggest that negative and positive outcomes of trauma are impacted by making negative and positive sense of adversity, respectively, via two separate pathways, both mediated by resilience. Our findings contribute to an understanding of the cognitive process of symptomatology and PTG in the HIV context. Theoretical considerations, clinical implications, and future directions are discussed.

The moderation effect of personality on healthcare utilization in Chinese people living with HIV.

There is evidence that Type D personality can predict impaired quality of life and health status in various chronic conditions. The evidence is conflicting as to whether Type D is associated with increased healthcare services, and no study has reported on the healthcare utilization of people living with HIV (PLWH) who have a Type D personality. This study investigated the impact of Type D personality on healthcare utilization in a sample of Chinese PLWH and examined physical and emotional symptoms as possible mechanisms of healthcare utilization. This was a cross-sectional study of 199 PLWH in rural China. Participants completed a survey on physical symptoms, emotional symptoms, healthcare utilization, and Type D personality. Those PLWH with a Type D personality reported more physical and emotional symptoms and healthcare utilization than patients without this personality. Among PLWH who had a Type D personality, physical symptoms had a direct effect on healthcare utilization, and emotional symptoms did not significantly mediate this association. However, among PLWH without a Type D personality, emotional symptoms significantly mediated the effects of physical symptoms on healthcare utilization. PLWH with a Type D personality reported more healthcare utilization, which was attributed to their high physical symptoms rather than their emotional symptoms. These findings suggest that PLWH with a Type D personality might be bothered by intensified emotional symptoms, which might be too severe to be associated with physical symptoms and healthcare utilization. New prospective studies should focus on the pattern of healthcare utilization among patients with a Type D personality and their intensified physical and emotional symptoms.
