This study reports the development of an inventory to assess the perceived internalized homophobia of gay men in a collectivistic Chinese cultural context. The results of exploratory and confirmatory factor analyses using two samples suggested the viability and stability of a three-factor model: internalized heteronormativity (IHN), family-oriented identity (FOI), and socially oriented identity (SOI). The 11-item internalized homophobia inventory demonstrated good internal consistency and construct validity. Internalized homophobia was related positively to the extent of a sense of loneliness and negatively to self-evaluation and the discrepancy in self-identification as a gay man. In addition, the participants’ internalized SOI consistently predicted their coming out choices in their social surroundings, while their FOI predicted their decisions to enter into heterosexual marriages. The findings suggest that sexual self-prejudice was correlated with IHN, family values, and social norms. The present research demonstrates that a culturally sensitive scale is necessary to understand the cultural and family-oriented values that influence gay Chinese men’s everyday lives, self-constructs, and behavioral choices.

Background: The chronic phase of post-traumatic stress disorder (PTSD) and the limited effectiveness of existing treatments creates the need for the development of potential biomarkers to predict response to antidepressant medication at an early stage. However, findings at present focus on acute therapeutic effect without following-up the long-term clinical outcome of PTSD. So far, studies predicting the long-term clinical outcome of short-term treatment based on both pre-treatment and post-treatment functional MRI in PTSD remains limited. Methods: Twenty-two PTSD patients were scanned using resting-state functional MRI (rs-fMRI) before and after 12 weeks of treatment with paroxetine. Twenty patients were followed up using the same psychopathological assessments 2 years after they underwent the second MRI scan. Based on clinical outcome, the follow-up patients were divided into those with remitted PTSD or persistent PTSD. Amplitude of low-frequency fluctuations (ALFF) and degree centrality (DC) derived from pre-treatment and post-treatment rs-fMRI were used as classification features in a support vector machine (SVM) classifier. Results: Prediction of long-term clinical outcome by combined ALFF and DC features derived from pre-treatment rs-fMRI yielded an accuracy rate of 72.5% (p < 0.005). The most informative voxels for outcome prediction were mainly located in the precuneus, superior temporal area, insula, dorsal medial prefrontal cortex, frontal orbital cortex, supplementary motor area, lingual gyrus, and cerebellum. Long-term outcome could not be successfully classified by post-treatment imaging features with accuracy rates <50%. Conclusions: Combined information from ALFF and DC from rs-fMRI data before treatment could predict the long-term clinical outcome of PTSD, which is critical for defining potential biomarkers to customize PTSD treatment and improve the prognosis.

Psychological disturbances are prevalent in people with burn injuries; however, psychological services are rarely accessiblepost-burn injury in China. The objective of this qualitative study was to explore and conceptualize the obstacles to delivering mental health care in burn injury patients. The researchers used a grounded theory research approach to interview sixteen burn injury patients, five nurses, four rehabilitation therapists, five medical doctors, and eight caregivers regarding their experiences with current health care services and barriers. An explorative model was generated from the data, and the relationships among the categories were identified. People’s beliefs, knowledge, socioeconomic status, cultural understanding of mental health, and social stigma appear to play key roles in the public health approach to post-burn health promotion and post-burn psychosocial interventions. The model proposed in our research highlights the need to focus on the underlying social, economic, and cultural determinants of mental health care. The underlying social determinants of the mental health care gap that is responsible for the ill-prepared health care must be addressed.

The purpose of this study was to begin to generate an exploratory model of the disaster-related mental health education process associated with the training experiences of psychological relief workers active during the Sichuan earthquake in China. The data consisted of semi-structured interviews with 20 psychological relief workers from four different professions (social workers, psychiatric nurses, psychiatrists, and counsellors) regarding their experiences in training and ideas for improvement. The model explains the need to use a people-centred community interprofessional education approach, which focuses on role-modelling of the trainer, caring for relief workers, paying attention to the needs of the trainee, and building systematic interprofessional education strategies. The proposed model identifies areas for the comprehensive training of relief workers and aims to address the importance of people-centred mental health service provisions, ensure intentional and strategic training of relief workers using interprofessional concepts and strategies, and use culturally attuned and community-informed strategies in mental health training practices.

Background: This research aims to explore the life experiences of relocated earthquake survivors with PTSD and develop a conceptual framework for understanding their life experiences.Method: Interviews were conducted with twenty-three participants. The participant selection, data collection and analysis were based on grounded theory methodology. A theoretical model called “loss of homeland” was developed.Results: Loss of homeland was the most important condition that influenced the relocated participants’ self-identity, social connections, and meaning system. These aspects were categorized into existential changes, lost connections, and changes in identity. Post-disaster relocation threatens individuals’ sense of meaning, integrity of self, and sense of belonging, affects every aspect of everyday life and shatters their inner and outer harmony.Conclusions: Further research guided by this theoretical model is needed to inform post-disaster mental health services and relocation policy. Mental health professionals and policy makers can make more informed decisions in terms of disaster relocation policy and manage post-disaster psychological disturbances by focusing on both places and people.
