This study describes the development and validation of Chinese, Malay and Tamil translations of the Positive Mental Health Instrument (PMHI) in a general population sample in Singapore. Translations were performed using two independent forward translations followed by expert panel discussions and tested for content, construct and language appropriateness using focus group discussions. The final translated tools were field-tested among 220 residents per language using self-administered questionnaires comprising the translated PMHI and other validity measures. Missing data, floor and ceiling effects, confirmatory factor analysis (CFA), internal consistency, item response theory differential item functioning (IRT-DIF) and criterion validity were assessed. A total of 10 PMHI-Chinese items, 26 PMHI-Malay items and six response categories and six PMHI-Tamil items were modified based on expert panel and focus group discussions. PMHI had low missing data and showed negative but acceptable skewness (<2) and kurtosis (<7) for all translations, except for the PMHI-Malay "spirituality" subscale (skewness: -2.8; kurtosis: 12.5). CFA showed that all three PMHI translations fulfilled the original six-factor-higher-order structure (RMSEA = 0.05, CFI = 0.962, TLI = 0.96). Cronbach's alpha coefficients for total PMHI were 0.958, 0.954, 0.945 and 0.949 in the overall sample and the Chinese, Malay and Tamil translations, respectively. The three translations of the PMHI showed expected and significant positive ( r = 0.116 to 0.663) and negative correlations ( r = −0.137 to −0.574) with established measures. The findings show that the Chinese, Malay and Tamil translations of the PMHI have high internal consistency and validity in this multi-ethnic population.

Background:Pathways to care studies in Singapore are of high interest given the cultural diversity and various sources of help available for those with mental illnesses, ranging from the more traditional to tertiary-level mental health care services.Aim:The current study aimed to explore the associations of patients' socio-demographic characteristics with pathways to first contact and duration of untreated mental illness.Method:A total of 402 participants were recruited through convenience sampling. A pathway to care form was used to gather systematic information about the sources of care utilized by participants before approaching a mental health professional. Data were analysed using multinomial logistic regression and multiple linear regression models to assess the associations.Results:Majority of participants reported primary care (36.0%) as their first point of contact, followed by non-formal sources of help (33.8%), specialist care (21.8%), police/court (4.0%), websites/media (3.3%) and religious/traditional treatment (1.3%). Those belonging to Malay and Indian ethnicity (vs Chinese) were more likely to make first contact with non-formal sources of help than primary care. Those who received a diagnosis of any mood or anxiety disorder (vs schizophrenia and related psychoses) were less likely to make first contact with specialist care or non-formal sources of help than primary care. Those who were separated/divorced/widowed were significantly associated with higher duration of untreated illness compared to those who were single. Participants whose family/relative initiated the first contact were significantly associated with a shorter duration of untreated illness compared to those who initiated first contact on their own.Conclusion:Findings suggest the determinants of the pathways to first contact and duration of untreated illness included diagnosis, ethnicity, marital status and family initiating the first contact. The pathways adopted by these participants need to be kept in mind for planning mental health programmes.

BACKGROUND: In recent years, behaviourally driven policies such as nudges have been increasingly implemented to steer desired outcomes in public health. This study examines the different nudges and the socio-demographic characteristics and lifestyle behaviours that are associated with public acceptance of lifestyle nudges. METHODS: The study used data from the nationwide Knowledge, Attitudes and Practices study (KAP) on diabetes in Singapore. Three types of nudges arranged in increasing order of intrusiveness were examined: (1) information government campaigns, (2) government mandated information and (3) default rules and choice architecture. Acceptance was assessed based upon how much respondents 'agreed' with related statements describing heathy lifestyle nudges. Multivariable linear regressions were performed with socio-demographics and lifestyle behaviours using scores calculated for each nudge. RESULTS: The percentage of respondents who agreed to all statements related to each nudge were: 75.9% (information government campaigns), 73.0% (government mandated information), and 33.4% (default rules and choice architecture). Respondents of Malay/Others ethnicity (vs. Chinese) were more likely to accept information government campaigns. Respondents who were 18 – 34 years old (vs 65 years and above), female, of Malay/Indian ethnicity (vs Chinese), were sufficiently physically active, and with a healthier diet based on the DASH (Dietary Approach to Stop Hypertension) score were more likely to accept nudges related to government mandated information. Respondents of Malay/Indian ethnicity (vs Chinese), and who had a healthier diet were more likely to accept default rules and choice architecture. CONCLUSION: Individuals prefer less intrusive approaches for promoting healthy lifestyle. Ethnicity and lifestyle behaviours are associated with acceptance of nudges and should be taken into consideration during the formulation and implementation of behaviourally informed health policies.
