Neuronal BAG3 attenuates tau hyperphosphorylation, synaptic dysfunction, and cognitive deficits induced by traumatic brain injury via the regulation of autophagy-lysosome pathway.

Growing evidence supports that early- or middle-life traumatic brain injury (TBI) is a risk factor for developing Alzheimer's disease (AD) and AD-related dementia (ADRD). Nevertheless, the molecular mechanisms underlying TBI-induced AD-like pathology and cognitive deficits remain unclear. In this study, we found that a single TBI (induced by controlled cortical impact) reduced the expression of BCL2-associated athanogene 3 (BAG3) in neurons and oligodendrocytes, which is associated with decreased proteins related to the autophagy-lysosome pathway (ALP) and increased hyperphosphorylated tau (ptau) accumulation in excitatory neurons and oligodendrocytes, gliosis, synaptic dysfunction, and cognitive deficits in wild-type (WT) and human tau knock-in (hTKI) mice. These pathological changes were also found in human cases with a TBI history and exaggerated in human AD cases with TBI. The knockdown of BAG3 significantly inhibited autophagic flux, while overexpression of BAG3 significantly increased it in vitro. Specific overexpression of neuronal BAG3 in the hippocampus attenuated AD-like pathology and cognitive deficits induced by TBI in hTKI mice, which is associated with increased ALP-related proteins. Our data suggest that targeting neuronal BAG3 may be a therapeutic strategy for preventing or reducing AD-like pathology and cognitive deficits induced by TBI.

The impact of having foreign domestic workers on informal caregivers of persons with dementia - findings from a multi-method research in Singapore.

BACKGROUND: Informal caregivers of persons with dementia (PWDs) sometimes engage foreign domestic workers (FDWs) to support their caregiving journey. However, there has not been much research to establish if this is really beneficial. The current study aims to investigate whether engaging FDWs specifically for caregiving of PWDs truly moderates caregiver stress and to explore caregivers' experiences of engaging FDWs. METHODS: A multi-method study design with a quantitative and qualitative sub-study was adopted. For the quantitative sub-study, 282 informal caregivers of PWDs were recruited. Propensity score matching analysis was used. For the qualitative sub-study, 15 informal caregivers with FDWs were interviewed. Inductive thematic analysis was conducted. RESULTS: The quantitative sub-study confirmed that engaging FDWs did moderate the depressive symptoms of informal dementia caregivers (marginal effect = -3.35, p = 0.0497). However, such support did not affect their caregiving burden, self-efficacy, and perceived positive aspects of caregiving. The qualitative sub-study suggested that engaging FDWs is an ambivalent experience, which entails both support and challenges. CONCLUSIONS: The current study confirmed previous research findings, that engaging FDWs moderated depressive symptoms among caregivers of PWDs, and it could be through their physical support such as in daily caregiving activities. Policy-makers may consider providing more subsidies to caregivers caring for PWDs with mobility issues to hire FDWs. They may also consider providing training to FDWs on dementia caregiving skills and improving the intake of such training as this might be helpful for both FDWs and caregivers during this journey.

The perspectives of healthcare professionals in mental health settings on stigma and recovery - A qualitative inquiry.

BACKGROUND: Mental health stigma is one of the most prominent barriers to recovery, and it is widely known that stigma may manifest differentially in different cultures. Healthcare professionals working closely with persons with mental illnesses (PMI) may provide important insights towards stigma that are otherwise unattainable from caregivers and consumers. However, there is a dearth of literature on healthcare professionals' perspectives on this topic. Thus, this study uses a multilevel approach to explore how stigma affects recovery from the perspectives of healthcare professionals that work closely with PMI in Singapore. METHODS: Semi-structured interviews were conducted with a total of 17 healthcare professionals who were working in mental health settings in Singapore. Participants were recruited via direct email invitation or through snowball sampling. Data collected was analysed with the inductive thematic analysis method. All coding and inter-rater analyses were performed with NVivo. RESULTS: The current study themes identified stigma-related factors that influence PMI's recovery from the perspectives of healthcare professionals working closely with PMI. These factors were organised into three overarching themes in a multilevel structure. The three themes were classified as Micro Factors (e.g., internalised stigma), Meso Factors (e.g., discrimination of people associated with the stigmatised group), and Macro Factors (e.g., structural stigma and stigma within healthcare settings). CONCLUSIONS: The findings of this study gave us a greater understanding of how stigma influences recovery in Singapore, which could be used to guide the development and implementation of future policies and strategies to promote recovery. Importantly, our results suggest that improving mental health literacy, addressing cultural misgivings towards mental illness, implementing recovery-oriented practices, and making insurance more accessible for PMI could mitigate the deleterious impact that stigma has on recovery.

A Qualitative Exploration of the Views of Policymakers and Policy Advisors on the Impact of Mental Health Stigma on the Development and Implementation of Mental Health Policy in Singapore.

Few studies have examined the views of policy makers regarding the impact of mental health stigma on the development and implementation of mental health policies. This study aimed to address this knowledge gap by exploring policymakers' and policy advisors' perspectives regarding the impact of mental health stigma on the development and implementation of mental health programmes, strategies, and services in Singapore. In all 13 participants were recruited for the study comprising practicing policymakers, senior staff of organisations involved in implementing the various mental health programmes, and policy advisors. Data was collected through semi-structured interviews, which were transcribed verbatim and analysed using reflexive thematic analysis. Data analysis revealed three superordinate themes related to challenges experienced by the policymakers/advisors when dealing with mental health policy and implementation of programmes. These themes included stigma as a barrier to mental health treatment, community-level barriers to mental health recovery, and mental health being a neglected need. Policymakers/advisors demonstrated an in-depth and nuanced understanding of the barriers (consequent to stigma) to mental healthcare delivery and access. Policymakers/advisors were able to associate the themes related to the stigma towards mental illness with help-seeking barriers based on personal experiences, knowledge, and insight gained through the implementation of mental health programmes and initiatives.

Advancing research to eliminate mental illness stigma: an interventional study to improve community attitudes towards depression among University students in Singapore.

BACKGROUND: After decades of anti-stigma initiatives, the Advancing Research To Eliminate Mental Illness Stigma (ARTEMIS) intervention study is one of the first in Singapore to evaluate the effects of an anti-stigma intervention on attitudes towards depression in university students. METHODS: 390 university students from a local university in Singapore were voluntarily recruited for the study. The ARTEMIS intervention comprises an educational and social contact component, as well as a question and answer (Q&A) session with experts in the area of mental health. The Community Attitudes towards Mental Illness (CAMI) scale was administered at baseline, post-intervention and at 3-months follow-up. A confirmatory factor analysis (CFA) was conducted. RESULTS: The CFA identified a 3-factor model for the CAMI with a decent fit (RMSEA = 0.06, CFI = 0.93, TLI = 0.93, SRMR = 0.06). Favourable shifts in attitudes across the factors were observed immediately after the intervention (p <  0.001). Gender (ß = - 1.19, 95% CI: - 2.10, - 0.27, p = 0.01) and nationality (ß = - 1.23, 95% CI: - 2.35, - 0.11, p = 0.03) were identified as significant correlates for the community mental health ideology (CMHI) factor. Linear effects indicated that having a close social contact with mental illness observed a smaller decrease in authoritarianism scores from pre- to post-intervention (ß = 0.85, 95% CI: 0.18, 1.53, p = 0.01); whereas quadratic effects found a greater decrease in scores from post-intervention to after 3-months for benevolence (ß = - 0.34, 95% CI: - 0.52, - 0.16, p <  0.001) and CMHI (ß = - 0.22, 95% CI: - 0.45, - 0.002, p = 0.048). CONCLUSION: The anti-stigma intervention shows promising short-term results across the CAMI dimensions even after adjusting for sociodemographic correlates. However, the intervention did not observe the sustained attitude shifts after 3-months. Recommendations for future anti-stigma interventions were also considered.

Combining a variable-centered and a person-centered analytical approach to caregiving burden - a holistic approach.

BACKGROUND: Informal caregivers of persons with dementia often experience elevated levels of caregiving burden. However, existing studies tend to use a variable-centered approach to explore it. This study aims to understand the caregiving burden of informal caregivers of persons with dementia in Singapore through a combination of variable-centered and person-centered analytical approaches, and explore the correlates of identified factors and latent classes of caregiving burden. METHODS: Zarit Burden Interview was used to gauge the caregiving burden of 282 primary informal caregivers of persons with dementia recruited through convenience sampling in Singapore. Factor analysis and latent class analysis were conducted to identify the latent factors and the latent classes of Zarit Burden Interview, followed by multiple linear regression and multinomial logistic regression to explore their significant correlates. RESULTS: The analyses suggested a 17-item 3-factor structure for Zarit burden interview and three mutually exclusive caregiving burden classes. Regression analyses found that caregiving related variables especially care recipients' memory and behaviour problems were correlated with both the factors and latent classes of caregiving burden. CONCLUSIONS: The combination of these two approaches suggests that caregivers experiencing higher burden on one domain are likely to experience higher burden on the other two domains. This further supports the point that more attention should be given to caregivers who experience an overall high burden. Future research could explore the generalizability of our findings among caregivers elsewhere and explore the type of support needed by caregivers, especially those experiencing high burden.

Factors associated with caregiving self-efficacy among primary informal caregivers of persons with dementia in Singapore.

BACKGROUND: Informal caregivers of persons with dementia (PWD) are often associated with negative health outcomes. Self-efficacy in dementia caregiving has been reported to have protective effects on caregiver's health. This study aims to examine the factors associated with the domains of caregiving self-efficacy among informal caregivers in Singapore, a country with a rapidly aging population and a 10% prevalence of dementia among older adults. METHODS: Two hundred eighty-two informal caregivers were recruited and data including participant's caregiving self-efficacy, sociodemographic information, perceived social support, positive aspects of caregiving, knowledge of dementia, as well as behavioral and memory problems of care recipients were collected. A confirmatory factor analysis (CFA) was performed for the 3-factor model of the Revised Scale for Caregiving Self-Efficacy (RSCSE), and multiple linear regressions were conducted using the RSCSE subscales as dependent variables. RESULTS: Our CFA found that the RSCSE 3-factor model proposed by the original scale developer was an acceptable fit among informal caregivers in Singapore. Having established that the 3-factor model of the RSCSE was compatible among our sample, a series of multiple regressions were conducted using each of the factors as a dependent variable. Regressions revealed several factors that were significantly associated with caregiving self-efficacy. Importantly, outlook on life was positively associated to all 3 domains of the RSCSE, while social support was positively associated with self-efficacy in obtaining respite and controlling upsetting thoughts. CONCLUSION: The 3-factor model of the RSCSE was found to be an appropriate fit for our sample. Findings from this study elucidated important novel insights into the factors that influences caregiving self-efficacy amongst informal caregivers in Singapore. Crucially, caregivers' outlook on life and social support should be improved in order to enhance their caregiving self-efficacy.

Dementia knowledge and its demographic correlates amongst informal dementia caregivers in Singapore.

Objectives: The Dementia Knowledge Assessment Scale (DKAS) is a validated assessment tool to measure dementia knowledge. However, the factor structure of the DKAS has yet to be validated in Singapore. This study aims to investigate the DKAS factor structure amongst a sample of informal dementia caregivers in Singapore, as well as their sociodemographic correlates.Methods: A total of 282 participants were evaluated on their knowledge of dementia by an interviewer administering the DKAS. Confirmatory factor analysis (CFA) of factor models proposed by previous study yielded poor fit for our sample. Thus, an exploratory factor analysis (EFA) was conducted. Multiple linear regression was then performed to examine the sociodemographic correlates of DKAS factors.Results: EFA revealed a 23-item 3-factor model - 'misconceptions about dementia' (MD), 'caregiving considerations towards dementia' (CD) and 'dementia symptoms' (DS). Being a male caregiver and having lower educational levels were associated with poorer scores on MD and CD.Conclusion: A 3-factor model of the DKAS was found to be more appropriate with the sample in this study. Findings from this study suggests the need for more dementia literacy intervention for caregivers of dementia patients in Singapore, especially for male caregivers and those of lower education levels.

Mental illness stigma's reasons and determinants (MISReaD) among Singapore's lay public - a qualitative inquiry.

BACKGROUND: Mental illnesses pose a significant burden worldwide. Furthermore, the treatment gap for mental disorders is large. A contributor to this treatment gap is the perceived stigma towards mental illness. Besides impeding one's help-seeking intentions, stigma also impairs persons with mental illness (PMI) in other aspects of their life. Studies have found that stigma may manifest differentially under different cultural contexts. Thus, this study seeks to elucidate the determinants of stigma towards PMI among lay public in Singapore using a qualitative approach. METHODS: A total of 9 focus group discussions (FGD) were conducted with 63 participants consisting of lay public Singaporeans who were neither students or professionals in the mental health field, nor had they ever been diagnosed with a mental illness. Topics discussed during the FGD were related to the stigma of mental illness. Data collected were analyzed with inductive thematic analysis method. A codebook was derived through an iterative process, and data was coded by 4 different coders. Both coding and inter-rater analysis were performed with NVivo V.11. RESULTS: In total, 11 themes for the determinants of stigma were identified and conceptualized into a socioecological model. The socioecological model comprised 4 levels of themes: 1) Individual level beliefs (fear towards PMI, perceiving PMI to be burdensome, dismissing mental illness as not a real condition), 2) Interpersonal influences (upbringing that instills stigma, intergroup bias, perceived inability to handle interactions with PMI), 3) Local cultural values (elitist mindset among Singaporeans, Chinese culture of "face", Islamic beliefs about spiritual possession and reaction towards PMI), and 4) Shared societal culture (negative portrayal by media, Asian values). CONCLUSIONS: The findings of this study improved our understanding of the various reasons why stigma exists in Singapore. The themes identified in this study concur with that of studies conducted overseas, as some determinants of stigma such as fear towards PMI are quite ubiquitous. Specifically, the themes elitist mindset among Singaporeans and perceived inability to handle interactions with PMI were unique to this study. It is highly recommended that future anti-stigma campaigns in Singapore should incorporate the findings of this study to ensure cultural misgivings and beliefs are addressed adequately.

The potential impact of an anti-stigma intervention on mental health help-seeking attitudes among university students.

BACKGROUND: The reluctance of young adults to seek mental health treatment has been attributed to poor mental health literacy, stigma, preference for self-reliance and concerns about confidentiality. The purpose of this study was to examine the potential impact of an anti-stigma intervention that includes education about depression, information about help-seeking as well as contact with a person with lived experience, on help seeking attitudes. METHODS: A pre-post study design was employed. Changes in help-seeking attitudes were measured using the Inventory of Attitudes towards Seeking Mental Health Services (IASMHS) immediately post-intervention and after 3 months. Sociodemographic data, information on past experiences in the mental health field and contact with people with mental illness were collated. Three hundred ninety university students enrolled in the study. Linear mixed models were used to examine the effects of the intervention. RESULTS: Scores on all subscales of the IASMHS, Psychological Openness (PO), Help-seeking Propensity (HP) and Indifference to Stigma improved significantly post-intervention and at 3-month follow-up compared to pre-intervention, with HP demonstrating the highest effect size. However, a significant decline was observed on all three scales at 3-month follow-up compared to post-intervention. Gender, having friends/family with mental illness, and previous experience in the mental health field moderated the intervention effects for the PO and HP subscales. CONCLUSION: The study showed that the brief anti-stigma intervention was associated with improvements in help-seeking attitudes among university students with differential effects among certain sub-groups. As the beneficial outcomes appeared to decrease over time, booster sessions or opportunities to participate in mental health-related activities post-intervention may be required to maintain the desired changes in help-seeking attitudes.

A qualitative enquiry on the impact of mental illness stigma on caregiving role and experiences in Singapore.

Introduction: Given that mental illness stigma is a common occurrence amongst people with mental illness and caregivers (CGs) can be a potential victim of stigma themselves, there is a need to examine caregivers' perspective on the phenomenon. This study is part of a larger study which aims to qualitatively examine the concept of mental illness stigma amongst different stakeholders in Singapore. Methods: Focus group discussions (FGDs) were conducted amongst 21 informal caregivers to explore the experience of stigma encountered by them and their care recipients, and how it may implicate their caregiving experience. Both inductive and deductive thematic analyses were employed to analyze the data. Results: Three overarching themes of stigma encounters that may have implication on caregiving experience were identified: 1) Stigma within the family; 2) Structural stigma; and 3) Stigma by association. Experience of stigma within family (e.g., social exclusion and lack of understanding) limits the caregiving supports available to CGs. CGs also took up a mediating role between their care recipients and other family who may hold stigmatizing views. Witnessing their care recipients being subjected to structural disadvantages (e.g., employment, school, and mandatory conscription) can induce emotional stresses amongst CGs and motivate them to protest and seek redress on their behalf. Furthermore, encounters of stigma themselves (e.g., being judged or blamed for their loved one's condition) also led to feelings of guilt and self-blame amongst the CGs. Discussion: These findings can aid the formulation of interventions in informing CGs on what to expect on their caregiving journey and supporting them in dealing with issues relating to stigma and highlight the importance of anti-stigma efforts in organizational settings such as schools, corporations, and government agencies.

Alternative splicing at C terminus of Ca(V)1.4 calcium channel modulates calcium-dependent inactivation, activation potential, and current density.

The Ca(V)1.4 voltage-gated calcium channel is predominantly expressed in the retina, and mutations to this channel have been associated with human congenital stationary night blindness type-2. The L-type Ca(V)1.4 channel displays distinct properties such as absence of calcium-dependent inactivation (CDI) and slow voltage-dependent inactivation (VDI) due to the presence of an autoinhibitory domain (inhibitor of CDI) in the distal C terminus. We hypothesized that native Ca(V)1.4 is subjected to extensive alternative splicing, much like the other voltage-gated calcium channels, and employed the transcript scanning method to identify alternatively spliced exons within the Ca(V)1.4 transcripts isolated from the human retina. In total, we identified 19 alternative splice variations, of which 16 variations have not been previously reported. Characterization of the C terminus alternatively spliced exons using whole-cell patch clamp electrophysiology revealed a splice variant that exhibits robust CDI. This splice variant arose from the splicing of a novel alternate exon (43*) that can be found in 13.6% of the full-length transcripts screened. Inclusion of exon 43* inserts a stop codon that truncates half the C terminus. The Ca(V)1.4 43* channel exhibited robust CDI, a larger current density, a hyperpolarized shift in activation potential by ∼10 mV, and a slower VDI. Through deletional experiments, we showed that the inhibitor of CDI was responsible for modulating channel activation and VDI, in addition to CDI. Calcium currents in the photoreceptors were observed to exhibit CDI and are more negatively activated as compared with currents elicited from heterologously expressed full-length Ca(V)1.4. Naturally occurring alternative splice variants may in part contribute to the properties of the native Ca(V)1.4 channels.

The small hydrophobic protein of the human respiratory syncytial virus forms pentameric ion channels.

The small hydrophobic (SH) protein is encoded by the human respiratory syncytial virus. Its absence leads to viral attenuation in the context of whole organisms, and it prevents apoptosis in infected cells. Herein, we have examined the structure of SH protein in detergent micelles and in lipid bilayers, by solution NMR and attenuated total reflection-Fourier transform infrared spectroscopy, respectively. We found that SH protein has a single α-helical transmembrane domain and forms homopentamers in several detergents. In detergent micelles, the transmembrane domain is flanked N-terminally by an α-helix that forms a ring around the lumen of the pore and C-terminally by an extended ß-turn. SH protein was found in the plasma membrane of transiently expressing HEK 293 cells, which showed pH-dependent (acid-activated) channel activity. Channel activity was abolished in mutants lacking both native His residues, His(22) and His(51), but not when either His was present. Herein, we propose that the pentameric model of SH protein presented is a physiologically relevant conformation, albeit probably not the only one, in which SH contributes to RSV infection and replication. Viroporins are short (∼100 amino acids) viral membrane proteins that form oligomers of a defined size, act as proton or ion channels, and in general enhance membrane permeability in the host. However, with some exceptions, their precise biological role of their channel activity is not understood. In general, viroporins resemble poorly specialized proteins but are nevertheless critical for viral fitness. In vivo, viruses lacking viroporins usually exhibit an attenuated or weakened phenotype, altered tropism, and diminished pathological effects. We have chosen to study the SH protein, 64 amino acids long, found in the human respiratory syncytial virus because of the effect of RSV on human health and the lack of adequate antivirals. We show that SH protein forms oligomers that behave as ion channels when activated at low pH. This study adds SH protein to a growing group of viroporins that have been structurally characterized. Although the precise biological role of this pentameric channel is still unknown, this report is nevertheless essential to fill some of the many gaps that exist in the understanding of SH protein function.

Strategies to Reduce Mental Illness Stigma: Perspectives of People with Lived Experience and Caregivers.

BACKGROUND: Reducing the stigma surrounding mental illness is a global public health priority. Traditionally, anti-stigma campaigns were led by mental health professionals/organisations and had an emphasis on increasing mental health literacy. More recently, it has been argued that people with lived experience have much to contribute in terms of extending and strengthening these efforts. The purpose of this paper was to elicit views and suggestions from people with lived experience (PWLE) as well as from informal caregivers of people with mental health conditions, on effective strategies to combat the stigma surrounding mental illness. METHODS: Six focus group discussions (FGDs) were carried out with PWLE recruited at outpatient services at the Institute of Mental Health, Singapore, and five FGDs were carried out with informal caregivers who responded to advertisements for the study between March and November 2018. In all, the sample comprised 42 PWLE and 31 caregivers. All the FGDs were transcribed verbatim and were analysed using thematic analysis. A pragmatic approach was adopted for the study, and the researchers did not assume any particular philosophical orientation. RESULTS: Four overarching themes depicting strategies to combat stigma were identified through thematic analysis. They were (1) raising mental health awareness, (2) social contact, (3) advocacy by influential figures or groups, and (4) the legislation of anti-discriminatory laws. CONCLUSIONS: These strategies were in line with approaches that have been used internationally to disrupt the process of stigma. Our study has further identified nuanced details on how these strategies can be carried out as well as possible areas of priority in the Singapore landscape.

Emergency department point-of-care ultrasound for upper extremity deep venous thrombosis ED POCUS for upper extremity DVT.

BACKGROUND: Upper extremity deep vein thrombosis (UEDVT) is an uncommon disease but has to be carefully considered in patients with isolated unilateral upper limb swelling due to its potential to cause devastating complications and sequelae such as pulmonary embolism and septic thrombophlebitis. Given the extreme rarity of this condition, it is not surprising that point-of-care ultrasonographic evaluation of the upper limb for deep venous thrombosis is hardly ever performed in the emergency department. This case report serves to highlight how point-of-care ultrasonographic evaluation of the upper extremity venous system could be incorporated as a tool in the diagnostic armamentarium of the emergency physician. CASE PRESENTATION: A 51-year-old Chinese gentleman presented to the emergency department with a 1-day duration of progressive right upper extremity swelling and pain. On examination, his hemodynamic parameters were stable with no tachycardia. He was noted to have a hyperaemic and grossly swollen but non-tender right upper limb. Distal pulses remained strong. Point-of-care ultrasonography of his right upper limb venous system with Doppler colour flow and single-point augmentation with the arm squeeze manoeuvre immediately confirmed the diagnosis of right upper extremity deep venous thrombosis, which in turn permitted anticoagulation to be instituted promptly whilst in the emergency department. CONCLUSION: The use of point-of-care ultrasonography of the upper limb venous system can prove invaluable as a rapid, non-invasive technique to facilitate expedient diagnosis of and early intervention for UEDVT in the emergency department.

Recognition of Depression and Help-Seeking Preference Among University Students in Singapore: An Evaluation of the Impact of Advancing Research to Eliminate Mental Illness Stigma an Education and Contact Intervention.

Background: The SMHS 2016 revealed that young adults in Singapore had the highest 12-month prevalence of mental disorders, with depression being the most prevalent condition. Additionally, the study found that those with higher education were less likely to seek treatment. The recognition of mental illness and knowledge of where to seek help has been found to influence one's ability to seek timely psychological help. This study thus aims to evaluate the effects of ARTEMIS, an education and contact intervention on university students' recognition of depression and help-seeking preference. Methods: A total of 390 university students were recruited over a period of 6-months (October 2018 to April 2019). Students had to attend a one-off intervention which comprised a lecture on depression and personal contact with a person with lived experience of mental illness. Recognition of depression and help-seeking preference were assessed using a vignette approach, at pre- and post-intervention as well as at 3-month follow-up. Results: The intervention was effective at improving student's recognition of depression and this effect was sustained at 3-months follow-up. The intervention was also effective in shifting student's help-seeking preference, although the effects were not sustained at 3-month follow-up. Having a close friend or family with mental illness was associated with better recognition, and being able to correctly recognize depression was linked to a preference to seek psychiatric over non-psychiatric help. Conclusion: This study elucidated the efficacy of a knowledge-contact-based intervention in improving university students' recognition of depression and help-seeking preference. However, while the benefits on recognition of depression is more enduring, it is more transient for help-seeking beliefs, and booster sessions may be needed to improve the long-term effectiveness of the intervention on help-seeking preference. Lastly, to investigate the generalizability of this study's findings, future studies could replicate the current one across other non-self-selected samples, such as by integrating the intervention as part of student's orientation.

Preliminary development of a bystander intervention scale for depression and the examination of socio-demographic correlates amongst Singapore university students.

BACKGROUND: Despite peer involvement having a positive impact on help-seeking behavior, there is a lack of a scale quantifying the possibility of an individual intervening upon noticing peers who show signs of depression. The aims of this study were to (1) develop a bystander intervention scale for depression that assesses the likelihood of university students intervening when a peer shows signs of depression based on the theory of bystander intervention, (2) identify the underlying factors contributing to the behavior, and (3) explore the socio-demographic correlates of the scale. METHODS: The proposed scale, the Bystander Intervention Scale for Depression (BISD), is a 17-item self-reported questionnaire that was developed based on existing bystander intervention theory and inputs from mental health experts. Data was collected as part of a larger study to evaluate the effectiveness of an anti-stigma intervention amongst university students from a local university. A total of 392 participants were recruited. Exploratory factor analyses were performed to identify the underlying factor structure. Multiple linear regressions were conducted to explore the socio-demographic correlates of the scale. RESULT: Four key factors were identified for the proposed scale: (1) Awareness of depression among peers; (2) Vigilance towards possible symptoms of depression; (3) Knowledge on how to intervene; (4) Acceptance of responsibility to intervene. Having experience in the mental health field was associated with all factors while having family members or friends with mental illness was associated with all factors except for knowledge on how to intervene. Students of older age were associated with higher vigilance towards possible symptoms of depression and knowledge on how to intervene. Those of non-Chinese ethnicity were associated with acceptance of responsibility to intervene. CONCLUSION: This study provides a preliminary tool to assess bystander intervention in depression amongst university students. This study identifies sub-groups of the student population that require more education to intervene with depressed peers and also informs the development of future strategies.

Daily Encounters of Mental Illness Stigma and Individual Strategies to Reduce Stigma - Perspectives of People With Mental Illness.

INTRODUCTION: A qualitative evaluation of mental illness stigma experienced by people with mental illness (PMI) is currently lacking in Singapore. This study aims to employ qualitative methods to identify the common encounters of mental illness stigma experienced by PMI in Singapore and uncover their individual strategies and efforts to reduce mental illness stigma. METHODS: This study is part of a larger research project that explores the concept of mental illness stigma among different stakeholders in Singapore. Focus group discussions (FGDs) were conducted with 42 PMI to collect qualitative data on their experience with mental illness stigma, including encounters of stigma and individual strategies to reduce stigma. The inductive thematic analysis method was employed to analyze the data. RESULTS: The eight emergent themes associated with encountering stigma in PMI's everyday life were categorized into two over-arching themes, public stigma (i.e., negative beliefs and attitudes, subjected to contemptuous treatment, social exclusion, over-scrutinizing, and receiving excessive care and concern) and structural stigma (i.e., the requirement to declare psychiatric conditions during job interviews, excluded from consideration after the declaration, and requirement of medical endorsements for employment). Four themes regarding PMI's individual strategies to reduce stigma were also identified (i.e., non-disclosure of condition, standing up for themselves, individual efforts in raising awareness, improving themselves, and living life as per normal). LIMITATIONS: Participants may be influenced by social desirability bias due to the presence of other participants in an FGD setting. Also, those who agreed to participate in the study may possess strong views or beliefs about mental illness stigma and may therefore be inherently different from those who refused to participate. CONCLUSION: Our findings on instances of public and structural stigma encountered by PMI in Singapore can guide policymakers with the development of future policies and strategies to reduce mental illness stigma in the Singapore society. Furthermore, our study also identified individual strategies that PMI employed to reduce mental illness stigma. However, the effectiveness of these strategies was unclear and little is known of their effect on PMI themselves. Hence, there is a need for future studies to examine these strategies.

Positive aspect of caregiving among primary informal dementia caregivers in Singapore.

BACKGROUND: The present study investigated the factor structure of positive aspects of caregiving (PAC) scale among primary informal caregivers providing care to persons with dementia (PWD) in Singapore. METHODS: 282 primary informal caregivers of PWD were recruited from the Institute of Mental Health, and Changi General Hospital and administered the 9-item PAC scale. A confirmatory factor analyses (CFA) was conducted to test the model fit of the 9-item PAC proposed by the scale developer and multiple linear regression was used to investigate the significant socio-demographic correlates. RESULTS: CFA showed that the 2-factor structure including 'Self-Affirmation' and 'Outlook on Life' had an acceptable model fit. After controlling for confounding variables, Malay caregivers were associated with higher scores on PAC and 'Self-Affirmation' compared to caregivers of other ethnicities. Caregivers with Secondary or below education level had higher PAC and 'Outlook on Life' scores. Caregivers who had received formal training scored higher in PAC, 'Self-Affirmation' and 'Outlook on Life'. DISCUSSION: The present study confirmed that the 2-factor structure of the 9-item PAC was suitable for informal caregivers of PWD in Singapore. The findings have important implications for locally available interventions to enhance caregiver's psychological well-being and reduce burden of care.

Causal beliefs of mental illness and its impact on help-seeking attitudes: a cross-sectional study among university students in Singapore.

OBJECTIVES: A considerable proportion of those who suffer from mental illnesses in Singapore do not seek any form of professional help. The reluctance to seek professional help could be due to misconceptions about the causes of mental illnesses. Research has shown that help-seeking attitudes can predict actual service use. As young adults are most at risk of developing mental illnesses, this study aims to elucidate the impact of causal beliefs about mental illness on help-seeking attitudes among university students in Singapore. DESIGN: Prior to attending an anti-stigma intervention, data on the Causal Beliefs about Mental Illness, Inventory of Attitudes towards Seeking Mental Health services and questions pertaining to sociodemographic background were collected from participants using a self-administered questionnaire. Multiple linear regressions were performed to examine the relationship between causal beliefs and help-seeking, as well as their sociodemographic correlates. SETTINGS: A university in Singapore. PARTICIPANTS: 390 students who were studying in a University in Singapore. RESULTS: Younger age was associated with higher scores on psychosocial attribution, while prior social contact with individuals with mental illness was significantly associated with lower scores on personality attribution. With regard to help-seeking attitudes; being a male and personality attribution were significantly associated with lower scores on 'Psychological Openness' and 'Indifference to Stigma', while psychosocial attribution was significantly associated with higher scores on 'Help-seeking Propensity'. Having prior social contact also predicted higher 'Psychological Openness', while being in Year 2 and 3 predicted lower scores on 'Indifference to Stigma'. CONCLUSION: Findings from this study suggest that help-seeking attitudes might be influenced by causal beliefs, with personality attribution being the most impairing. Hence, to reduce the wide treatment gap in Singapore, anti-stigma interventions targeting young people could focus on addressing beliefs that attribute mental illness to the personality of the individual.
