Socio-demographic factors and psychological distress in Indigenous and non-Indigenous Australian adults aged 18-64 years: analysis of national survey data

Correlates of mental disorder and harmful substance use in an indigenous Australian urban sample: an analysis of data from the Queensland Urban Indigenous Mental Health Survey

PURPOSE

Limited data exists on the relationship between sociodemographic and cultural variables and the prevalence of specific mental and substance use disorders (MSDs) among Indigenous Australians, using diagnostic prevalence data. This paper utilises data from the Queensland Urban Indigenous Mental Health Survey (QUIMHS), a population-level diagnostic mental health survey, to identify socioeconomic and cultural correlates of psychological distress and specific MSDs in an urban Indigenous Australian sample.

METHODS

Using a mixture of household sampling (door-knocking) and snowball sampling (promotion of the survey in the community), 406 participants aged 18 to 89 were recruited across key locations in Southeast Queensland. The study investigated various demographic, socioeconomic, and cultural factors as predictors of psychological distress (measured by the Kessler-5) and MSD diagnoses (utilising the Composite International Diagnostic Interview, CIDI 3.0) using a series of univariate logistic regressions.

RESULTS

Individuals in unstable housing (homeless, sleeping rough) and those reporting financial distress were more likely to experience an MSD in the past 12 months and throughout their lifetime. Individuals reporting lower levels of connection and belonging, limited participation in cultural events, and lower empowerment were more likely to have a lifetime mental disorder.

CONCLUSION

This data emphasises the importance of addressing systemic and social determinants of health when designing and delivering community mental health services and underscores the need for holistic approaches when working with Indigenous communities.

Clinicians' views on cognitive assessment with Aboriginal Australians

BACKGROUND

A shortage of standardised cognitive assessment tools for use with Aboriginal Australians is evident. Clinicians also miss the range of guidelines necessary to inform test selection and interpretation for all Aboriginal clients. This mixed methods study examines clinicians' confidence, views and current practices when conducting cognitive assessments with Aboriginal Australian clients.

METHODS

Clinicians were asked about factors that influence their likelihood of using standardised testing in Aboriginal vs non-Indigenous Australian people. Twenty-one health professionals with experience conducting cognitive assessments with Aboriginal and non-Aboriginal Australians participated. Clinicians were presented with a series of different scenarios per the client's level of education and language of origin via an online survey. Clinicians rated their likelihood and confidence using standardised cognitive assessment for each scenario. Open-ended questions captured clinicians' views and information about their current clinical practices.

RESULTS

Clients' age, education and language of origin influence the likelihood of clinicians' use of standardised cognitive assessment measures with Aboriginal people. Overall, clinicians reported feeling only slightly more confident working with non-Indigenous clients than Aboriginal clients. Qualitative data indicate a lack of consistency regarding test selection.

CONCLUSION

Clinicians expressed concerns about the validity of available cognitive assessment tools for use with Aboriginal Australians and the absence of evidence to assist decision-making. Cited barriers included language, educational attainment and cultural factors.

The perinatal and childhood outcomes of children born to Indigenous women with mental health problems: A scoping review

OBJECTIVE

Maternal mental health problems are common during the perinatal period and have been associated with several negative outcomes in children. However, few studies have examined the associations between maternal mental health problems and offspring outcomes among Indigenous people, and the findings across these studies have been inconsistent. This scoping review examined the birth and childhood (≤12 years) health and development outcomes of the children of Indigenous women with mental health problems.

METHODS

A scoping review was conducted following the methodological framework developed by Arksey and O'Malley and based on the PRISMA-ScR guidelines. Eight databases were searched electronically for studies examining the associations between any perinatal maternal mental health problems and birth and childhood outcomes among the Indigenous populations of Australia, Canada, New Zealand, and the USA. Two authors reviewed studies for inclusion. A narrative synthesis approach was adopted.

RESULTS

Of 2,836 records identified, 10 were eligible. One of three studies evaluating maternal depression and anxiety problems found a negative (adverse) association with birth and childhood behavioural outcomes. Six of seven studies that examined the associations between maternal substance use disorder (mainly alcohol use disorder) and several birth and childhood outcomes found at least one negative association.

CONCLUSIONS AND IMPLICATIONS FOR PRACTICE

Maternal substance use disorder appears to be associated with adverse birth and childhood outcomes among some Indigenous populations. However, there is preliminary evidence for the other common maternal mental health problems. Further research is critically required to draw definitive conclusions regarding the impact of maternal mental health problems on the birth and childhood outcomes.

Coupling Machine Learning Models with Innovative Technology-based Screening Tool for Identifying Psychological Distress among Aboriginal Perinatal Mothers

Aboriginal perinatal mothers are at a significant risk of experiencing mental health problems, which can have profound negative impacts, despite their overall resilience. This work aimed to build prediction models for identifying high psychological distress among Aboriginal perinatal mothers by coupling machine learning models with an innovative and culturally-safe screening tool. The original dataset of 179 Aboriginal mothers with 337 variables was obtained from twelve perinatal health settings at Perth metropolitan and regional centers in Western Australia between July and September 2022, using a specifically designed web-based rubric for the perinatal mental health assessment. After data preprocessing and feature selection, 23 variables related to emotional manifestations, the problematic partner, worries about daily living, and the need for follow-up wraparound support were identified as significant predictors for the high risk of psychological distress measured by the Kessler 5 plus adaptation. The selected predictors were used to train prediction models, and most of the chosen machine learning models achieved satisfactory results, with Random Forest and Support Vector Machine yielding the highest AUC of over 0.95, accuracy over 0.86, and F1 score above 0.87. This study demonstrates the potential of using machine learning-based models in clinical decision-making to facilitate healthcare and social and emotional well-being for Aboriginal families.

Trust, privacy, community, and culture: Important elements of maternity care for Aboriginal and Torres Strait Islander women giving birth in Victoria

BACKGROUND

The Australian maternity system must enhance its capacity to meet the needs of Aboriginal and Torres Strait Islander (First Nations) mothers and babies, however evidence regarding what is important to women is limited.

AIMS

The aim of this study was to explore what women having a First Nations baby rate as important for their maternity care as well as what life stressors they may be experiencing.

METHODS

Women having a First Nations baby who booked for care at one of three urban Victorian maternity services were invited to complete a questionnaire.

RESULTS

343 women from 76 different language groups across Australia. Almost one third of women reported high levels of psychological distress, mental illness and/or were dealing with serious illness or death of relatives or friends. Almost one quarter reported three or more coinciding life stressors. Factors rated as most important were privacy and confidentiality (98 %), feeling that staff were trustworthy (97 %), unrestricted access to support people during pregnancy appointments, (87 %) birth (66 %) and postnatally (75 %), midwife home visits (78 %), female carers (66 %), culturally appropriate artwork, brochures (68 %) and access to Elders (65 %).

CONCLUSIONS

This study provides important information about what matters to women who are having a First Nations baby in Victoria, Australia, bringing to the forefront social and cultural complexities experienced by many women that need to be considered in programme planning. It is paramount that maternity services partner with First Nations communities to implement culturally secure programmes that respond to the needs of local communities.

Longitudinal Association of Physical Activity, Mastery and Psychological Distress in Mid-Aged Adults over 9-Years

Psychological distress is highly prevalent and associated with significant adverse health outcomes and economic burden. Mastery and physical activity are potential resources to reduce distress and promote wellbeing; however, previous research has not examined their potential interactive relationship over time. The purpose of this study was to explore associations between mastery, physical activity, and distress in mid-aged adults over nine years. Data from a longitudinal mail survey study including the Kessler 6, Pearlin Mastery Scale, and items assessing time spent in physical activity were examined in a sample of 4404 adults aged 40 to 54 years at baseline. Group-Based Trajectory Models identified two distinct trajectories of psychological distress (elevated and low). Generalized Estimating Equations were used to assess mastery and physical activity, adjusting for sociodemographic and health variables, as predictors for the probability of distress group membership. The odds of elevated distress over time were significantly reduced in people with higher mastery (OR = 0.13; 95% 0.11-0.15) and doing at least 150 min/week of physical activity (OR = 0.81; 95% 0.68-0.96). There was no significant interaction between mastery and physical activity. Mastery and physical activity may be important resources to mitigate distress and further research is needed to evaluate interventions promoting these resources and the impact on mid-aged adults experiencing psychological distress.

First episode of psychosis in Guam: The role of ethnicity and neighbourhood factors

OBJECTIVE

Ethnicity, neighbourhood ethnic density, and four additional neighbourhood factors (urbanicity, crime, voting, and poverty) were examined in relation to the incidence of first episode of psychosis (FEP) in the Pacific Island of Guam.

METHODS

All first contact patients seen at the Guam Department of Mental Health and Substance Abuse (DMHSA) between January 2005 and December 2007 that met DSM-IV criteria for the diagnosis of a psychotic disorder were included. At the time of the study, DMHSA was the only psychiatric facility in Guam.

RESULTS

After controlling for age and gender, Chamorros, the indigenous people of Guam, had a standardized incidence rate (IR = 151/100 000 person-years, 95%CI = 129-173) of FEP over twice that of Whites (IR = 66/100 000 person-years, 95%CI = 34-99). Individuals from Palau had the highest standardized incidence rate (IR = 832/100 000 person-years, 95%CI = 581-1083). Increased neighbourhood Chamorro density was associated with decreased incidence of FEP among Chamorro individuals (IRR = 0.11, 95%CI = 0.03-0.43). After controlling for age, gender, ethnicity, and other neighbourhood factors, urbanicity (IRR = 3.82, 95%CI = 1.86-7.81), voting (IRR = 2.06, 95%CI = 1.32-3.20), poverty (IRR = 1.94, 95%CI = 1.40-2.67), and crime (IRR = 1.18, 95%CI = 1.00-1.40) remained statistically associated with FEP incidence.

CONCLUSIONS

The findings add to prior research that suggests that rates of mental health problems are higher in indigenous than in settler communities and are highest for indigenous people who live in neighbourhoods with few other indigenous individuals. Findings also suggest that even on a small island, with only ~150 000 people, urbanicity is associated with FEP. Finally, results are consistent with other research suggesting that the reduction of crime and social adversity can play a positive role in reducing the incidence of first episode psychosis.

Sleep disorders among Aboriginal Australians with Machado-Joseph Disease: Quantitative results from a multiple methods study to assess the experience of people living with the disease and their caregivers

Background

Machado-Joseph Disease (MJD), or Spinocerebellar Ataxia Type 3 (SCA3), is a genetic disorder that causes progressive muscle weakness, loss of motor control, ataxia and permanent physical disability. Sleep disturbances are associated with MJD but remain poorly understood.

Objective

To investigate frequency and characteristics of sleep disorders and their association with health-related quality of life and psychosocial wellbeing for Aboriginal Australians living with MJD.

Methods

A convenience sample of MJD participants n = 24 participated in a semi-attended, ambulatory diagnostic sleep study to capture polysomnography, actigraphy and sleep diary data. Self-report measures collected were the Pittsburgh Sleep Quality Index (PSQI), STOP-BANG Questionnaire for Obstructive Sleep Apnoea (OSA), International Restless Legs Syndrome Study Group rating scale (IRLS), Kessler-5 (K5) and EuroQoL-5 Dimension (EQ5D). Caregivers (n = 22) reported EQ-5D, K5 and bed partners’ sleep behaviour (Mayo Sleep Questionnaire-Informant). Environmental factors were measured.

Results

We observed Nocturia, Sleep Related Leg Cramps, OSA, REM Behaviour Disorder, and RLS, respectively in 100%, 71%, 47%, 43%, and 33% of participants with a significant positive correlation between Body mass index (BMI) and Apnoea hypopnea index (AHI). The majority of sleep was spent in non-rapid eye movement sleep (NREM)-N2 stage (77.8% (67.7, 81.6)). Overcrowding (92%) and overnight care needs (42%) interrupted sleep. MJD participants and caregivers reported high psychological distress (K5 median 12.5 IQR 7, 16.5 & 8 IQR 6, 12 respectively).

Conclusion

Poor sleep quality and sleep disturbances are prevalent among this cohort. Disease manifestations and environmental factors are driving factors. Larger sample sizes are required to predict risk factors and confirm observed associations.

•

Aboriginal People living with MJD in Australia experience numerous sleep disorders.

•

Majority of sleep was spent in non-rapid eye movement sleep.

•

Overcrowding and overnight care needs interrupt sleep.

•

MJD participants and caregivers reported high psychological distress.

Cohort study comparison of Mental Health and Wellbeing Services delivered by The Royal Flying Doctor Service, across Far North and Central West Queensland

Background

Understanding cultural differences between geographical regions is essential in delivering culturally appropriate healthcare. We aimed to describe the characteristics and outcomes of diverse clients using the Far North Mental Health and Wellbeing Service (FNS) and the Central West Health and Wellbeing Service (CWS).

Methods

We conducted a cohort study within Queensland, Australia, on all clients who received a mental health therapy session at either the FNS or the CWS. Patient data was prospective data collected form July 2019 to December 2020.

Findings

There were1202 clients, with a median number of individual contacts per-client of 3.0 (IQR 2.0-6.0). There was 428 (35.6% 95% CI 32.90-38.39) males and 772 (64.2% 95% CI 61.44-66.94) females with a median age across the genders of 38.0 (IQR 28.0-51.0). There was 505 (42.0% 95% CI 39.20-44.86) identifying as Indigenous and 697 (58.0% 95% CI 55.14-60.80) as non-Indigenous Australians. The FNS had a significantly higher proportion of Indigenous clients (n=484; 54.8% 95% CI 51.46-58.13) as compared to the CWS (n=21; 6.6% 95% CI 4.12-9.89). Of the 1202 clients, 946 (78.7% 95% CI 76.28-80.99) had a socio-economic classification of ‘most disadvantaged’, consisting of 740 (83.8%) clients from the FNS and 206 (64.6%) clients from the CWS. The majority of presentations were for neurotic, stress-related and somatoform disorders (n=568; 47.3%), followed by mood affective disorders (n=310; 25.8%). The overall number of treatments strategies employed was 10798, equalling a median of 6.0 (IQR 4.0-9.0) strategies per-client, with the leading strategies being counselling/psychosocial (n=1394; 12.9%), reflective listening (n=1191; 11.0%), and strengths based reasoning (n=1116; 10.3%). There were 511 (42.5%) clients who completed the Kessler Psychological Distress Scale (K10/K5), with 493 (41.0%) clients not offered as deemed not culturally appropriate by the treating team. The mean initial K10/K5 score was 23.7 (SD 9.4) which significantly decreased (p<0.001) to 18.0 (SD 10.0) at final consultation.

Interpretation

This study highlighted client socioeconomic differences between two geographically remote mental health services. It is essential that services are regionally co-designed to ensure cultural appropriateness.

Funding

No funding to declare.

An exploration of the sociodemographic and health conditions associated with self-rated wellbeing for Aboriginal and Torres Strait Islander adults

Objective

To identify sociodemographic factors and health conditions associated with self-rated wellbeing for Aboriginal and Torres Strait Islander adults. Participants were recruited via investigator networks and an online panel provider with an established nationwide panel of Aboriginal and Torres Strait Islander adults. Those interested were invited to complete a survey that included an assessment of wellbeing using a visual analogue scale. Data was collected from October–November 2019 and August–September 2020. Exploratory analyses were conducted to ascertain factors associated with self-rated wellbeing for Aboriginal and Torres Strait Islander adults.

Results

Having more than enough money to last until next pay day, full-time employment, completion of grade 12, having a partner, and living with others were significantly associated with higher wellbeing among Aboriginal and Torres Strait Islander adults. A self-reported history of depression, anxiety, other mental health conditions, heart disease, or disability were associated with lower self-rated wellbeing scores. Our findings indicate a need for further investigation among these socioeconomic and patient groups to identify how to improve and support the wellbeing of Aboriginal and Torres Strait Islander adults.

Traumatic life events and risk of post-traumatic stress disorder among the Indigenous population of regional, remote and metropolitan Central-Eastern Australia: a cross-sectional study

OBJECTIVE

Trauma is reported by 70% of the global population and 4% of those exposed develop post-traumatic stress disorder (PTSD), but data from Indigenous populations are limited. We aimed to determine the prevalence, types and age of occurrence of traumatic events among community-living Indigenous Australians and associations with PTSD.

DESIGN

Lifetime trauma and PTSD were quantified among a broadly representative sample of 544 Indigenous participants using a diagnostic clinical interview. Logistic regression examined predictors of PTSD.

SETTING

Metropolitan, regional and remote areas of Southern Queensland and Northern New South Wales.

PARTICIPANTS

Indigenous Australians 18 years and older.

OUTCOME MEASURES

Prevalence of traumatic life events and risk of PTSD.

RESULTS

64.9% of participants (standardised prevalence 62.6%) reported lifetime trauma, with more than one trauma category in 62.3%. Females reported 2.3 times more sexual violence, otherwise no gender differences existed. The prevalence of four common trauma categories were 1.7-3.0 times higher than in the Australian population; physical violence being the highest relative risk. Although overall childhood trauma was not increased, sexual or physical violence before age 15 was twice more common than in the Australian population.The standardised prevalence of 12-month PTSD was 13.3% (95% CI 10.4 to 16.1), 16.1% (95% CI 12.2 to 19.9) in females and 8.2% (95% CI 5.3 to 11.1) in males, three times the Australian rates. In multiple regression analysis, independent predictors of PTSD were female gender (OR 2.1), rural residence (OR 3.0), trauma under age 10 (OR 2.2), sexual (without physical) violence (OR 2.5), physical (without sexual) violence (OR 2.3), and both sexual and physical violence (OR 5.0).

CONCLUSION

Indigenous Australians are more likely to experience potentially harmful traumas and develop PTSD than other Australians. Mitigation of trauma among Indigenous Australians, particularly childhood exposure and sexual or physical violence, is essential to reduce their high burden of PTSD.

Coronavirus disease 2019 (COVID-19) and psychological distress in China: Does neighbourhood matter?

Using individual data (n = 937) obtained from an online questionnaire between 20th January and 13th February, the early stage of the outbreak of the Coronavirus Disease 2019 (COVID-19) in 2020, we explore the direct association between people's perceptions of Coronavirus Disease 2019 (COVID-19) and psychological distress. We further examine the moderating role of neighbourhood environment and this distress. We find that people living in infected communities tend to perceive higher level of psychological distress compared to people living in uninfected communities. People's expected duration of COVID-19 is associated with higher psychological distress and this is partially moderated by the perception of neighbourhood noise level and overall environment quality. Additional results quantify the evidence that a quiet and well maintained neighbourhood environment could reduce the negative influences of expectation of a long duration of COVID-19 on people's psychological distress.

Prevalence of psychiatric disorders for Indigenous Australians: a population-based birth cohort study

AIMS

Limited information exists about the prevalence of psychiatric illness for Indigenous Australians. This study examines the prevalence of diagnosed psychiatric disorders in Indigenous Australians and compares this to non-Indigenous Australians. The aims were to: (1) determine prevalence rates for psychiatric diagnoses for Indigenous Australians admitted to hospital; and (2) examine whether the profile of psychiatric diagnoses for Indigenous Australians was different compared with non-Indigenous Australians.

METHODS

A birth cohort design was adopted, with the population consisting of 45 141 individuals born in the Australian State of Queensland in 1990 (6.3% Indigenous). Linked administrative data from Queensland Health hospital admissions were used to identify psychiatric diagnoses from age 4/5 to 23/24 years. Crude lifetime prevalence rates of psychiatric diagnoses for Indigenous and non-Indigenous individuals were derived from the hospital admissions data. The cumulative incidence of psychiatric diagnoses was modelled separately for Indigenous and non-Indigenous individuals. Logistic regression was used to model differences between Indigenous and non-Indigenous psychiatric presentations while controlling for sociodemographic characteristics.

RESULTS

There were 2783 (6.2%) individuals in the cohort with a diagnosed psychiatric disorder from a hospital admission. The prevalence of any psychiatric diagnosis at age 23/24 years was 17.2% (491) for Indigenous Australians compared with 5.4% (2292) for non-Indigenous Australians. Indigenous individuals were diagnosed earlier, with overrepresentation in psychiatric illness becoming more pronounced with age. Indigenous individuals were overrepresented in almost all categories of psychiatric disorder and this was most pronounced for substance use disorders (SUDs) (12.2 v. 2.6% of Indigenous and non-Indigenous individuals, respectively). Differences between Indigenous and non-Indigenous Australians in the likelihood of psychiatric disorders were not statistically significant after controlling for sociodemographic characteristics, except for SUDs.

CONCLUSIONS

There is significant inequality in psychiatric morbidity between Indigenous and non-Indigenous Australians across most forms of psychiatric illness that is evident from an early age and becomes more pronounced with age. SUDs are particularly prevalent, highlighting the importance of appropriate interventions to prevent and address these problems. Inequalities in mental health may be driven by socioeconomic disadvantage experienced by Indigenous individuals.

Prevalence and factors associated with suicide ideation and psychiatric morbidity among inpatients of a general hospital: A consecutive three-year study

Using a self-administered questionnaire (the five-item Brief Symptom Rating Scale, BSRS-5), determine the prevalence of suicide ideation (SI), psychiatric morbidity (PM), and the factors associated with these conditions in a general hospital in Taiwan. All individuals aged 12 years or older, who were admitted to a Medical University Hospital between August 2014 and December 2016, were asked to fill out the BSRS-5 at admission. The study was conducted in a medical inpatient setting, excluding Intensive Care Units and the Emergency Service Department. The 93,129 participants were recruited for analysis. Pearson's correlation, regression analysis and path analysis were performed to test the association between SI and each item of psychopathology and to determine the discrimination validity of individual BSRS-5 items for predicting SI. The prevalence rate was 2.3% for SI and 2.0% for PM among all participants. PM was more prevalent in females and those aged 25-54 years. Individuals with PM had a significantly higher rate of SI (44.6%) than did others (1.4%). The prevalence of PM was varied by department, e.g., Psychiatry (44.3%), Rehabilitation Medicine (7.9%), and Nephrology (5.2%). The regression analysis and path analysis with structural equation model indicated that depression, hostility, anxiety, and inferiority were significant independent predictors of SI. The BSRS-5 is an efficient and useful screening tool to identify psychological distress and SI among inpatients in a general hospital. Its integration into the electronic medical chart facilitates identifying patients at risk.

School-Based Prevention in Very Remote Settings: A Feasibility Trial of Methods and Measures for the Evaluation of a Social Emotional Learning Program for Indigenous Students in Remote Northern Australia

Purpose: Skills for Life (SFL) is a social-emotional curriculum for Indigenous middle school students that was co-developed with educators and community members in a remote community of northern Australia. This preliminary study aimed to test the feasibility of processes and methods of data-gathering, the reliability of youth self-report measures, and to identify the direction of effects for an evaluation of a longer-term pilot of the curriculum.

Design/Methodology/Approach: Indigenous Students in years 7–9 of a remote school participated in SFL over 2 years. The Strengths and Difficulties Questionnaire (SDQ), Kessler 6 (K6), and a purpose-designed Connected Self Scale (CSS) were administered to 63 students pre- and post-program.

Findings: Only the K6, Prosocial behavior (SDQ), and two CSS subscales showed sufficient internal consistency for analysis. Change was positive but non-significant for SDQ and CSS. There was evidence of a dosage effect: students receiving the intervention over 2 years showed greater reduction in psychological distress than other students. There was no evidence of iatrogenic effects.

Conclusions: The feasibility pilot is a critically important phase in the development of evaluation design and cjhoice of evaluation measures for challenging remote settings. This study found that evaluation of SFL with culturally and linguistically distinct Indigenous middle school students using self-report measures is feasible. However, the SDQ may not be suitable for this project. High levels of psychological distress suggest the need to investigate sources of life stress and potential supports for adolescent resilience in this context. This preliminary pilot aimed to trial methods and measures for evaluation of a social-emotional curriculum developed specifically for remote Australian Indigenous students who are at risk of poor psychosocial outcomes. No studies have examined the appropriateness of standardized self-report measures for evaluation of SEL with this student population in remote school settings.

The prevalence, severity and experience of food insecurity in Australia: An investigation of food aid use

High costs of living and low wage growth in Australia have resulted in an increase in the number of people experiencing food insecurity, and a corresponding increase in the number of people accessing food aid. This research employs qualitative methods alongside standard methods to explore food security to investigate these issues in food aid settings in Victoria, Australia. The two aims of this study were, 1) to explore the profile of people who access food aid and 2) to explore the experiences of people accessing food aid. A convenience sample of people was recruited from organisations that distribute food aid from across the state. People in need of food aid typically self-refer to charities, who then apply varied and localised criteria to manage access to the charitable service. Interviews were conducted with 78 participants between June 2018 and January 2019. Participants had been accessing food aid for 4 years on average (SD 5.7, range 1 month-40 years), most participants were female (n = 57, 73.1%), with an average age of 52.6 years (SD 15.9), and over half were born in Australia (n = 44, 56.4%). Most participants were in receipt of a government welfare payment (n = 75, 96.2%), and over 40% were living in private rental accommodation. Around two thirds of participants reported low or very low food security (n = 54, 67.5%). Participants reported a range of both positive and negative experiences accessing food aid. This study adds to the body of literature exploring food insecurity in high-income settings and its persistence despite significant national economic prosperity. Current economic and political conditions in Australia mean that the reliance on food aid by welfare recipients is unlikely to decrease.

Telehealth and indigenous populations around the world: a systematic review on current modalities for physical and mental health

Approximately 370-500 million Indigenous people live worldwide. While Indigenous peoples make up only 5% of the world's population, they account for 15% of the extreme poor and have life expectancy that is 20 years shorter than that of non-Indigenous people. Access to healthcare has been identified as an important social determinant of health and key driver of health outcomes. Indigenous populations often face barriers to accessing healthcare including living in remote areas, lacking financial resources, and having cultural differences. Telehealth, the utililzation of any synchronous modality, including phone, video, or teleconferencing technology used to support the provision of long-distance health care and health education, is a feasible and cost-effective treatment delivery mechanism that has successfully addressed access barriers faced by vulnerable populations globally, however, few studies have included indigenous populations and the application of this technology to improve physical and mental health outcomes. This systematic review aims to identify trials that were conducted among Indigenous adults, and to summarize the components of interventions that have been found to effectively improve the health of Indigenous peoples. The PRISMA guidelines for reporting of systematic reviews were followed in preparing this manuscript. Studies were identified by searching PubMed, Scopus, and PsychInfo databases for clinical trial articles on Indigenous peoples and mental and physical health, published between January 1, 1998 and December 31, 2018. Eligibility criteria for determining studies to include in the analysis were as follows: (I) ≥18 years of age; (II) indigenous peoples; (III) any technology-based intervention; (IV) studies included at least one of the following mental health (depression, post-traumatic stress disorder, suicide) and physical health (mortality, blood pressure, hemoglobin A1C, cholesterol, quality of life) outcomes; (V) clinical trials. A total of 2,662 articles were identified and six were included in the final review based on pre-specified eligibility criteria. Three were conducted in the United States, one study was conducted in Canada, and two were conducted in New Zealand. Study sample sizes ranged from 20 to 762, intervention delivery times ranged from three to 20 months and utilized telephone, internet and SMS messaging as the type of technology. There is a paucity of evidence on the use of telehealth programs to increase access to chronic disease programs in Indigenous populations. This review highlights the importance of culturally tailoring programs despite the modality in which they are delivered, and recommends telephone-based delivery facilitated by a trained health professional. Telehealth has great promise for meeting the health needs of highly marginalized Indigenous populations around the world, however, at this point more research is needed to understand how best to structure and deliver these programs for maximum effect.

Prevalence of psychological distress, depression and suicidal ideation in an indigenous population in Panamá

OBJECTIVE

The aim of this study was to investigate the prevalence of serious psychological distress (SPD), depression, and suicidal ideation in an adult Indigenous population in Panamá.

METHODS

Data were collected from 211 Kuna adults using a paper-based survey. Depression and suicidal ideation were measured using the Patient Health Questionnaire (PHQ-9), and SPD was measured using the Kessler-6. Univariate analyses were used to describe demographic variables, followed by chi² tests to compare differences in demographic variables for each of the mental health outcomes (depression, serious psychological distress, suicidal ideation). A regression model, adjusted for all demographic variables, was then run for each mental health outcome to understand independent correlates.

RESULTS

Within the sample surveyed, 6.2% (95% CI 3.4-10.4) reported serious psychological distress, 32.0% (95% CI 25.7-38.9) reported depression, and 22.9% (95% CI 17.4-29.1) reported suicidal ideation. Significant demographic differences existed with 14% of individuals between the age of 60-90 and 17% of individuals with no education reporting SPD. Women were nearly 5 times more likely to report depression than men (OR 4.90, 95% CI 1.27-19.00) and those with higher incomes were less likely to report depression (OR 0.32, 95% CI 0.13-0.78).

CONCLUSION

High levels of depression, SPD, and suicidal ideation were present in an Indigenous Kuna community in Panamá. Women and individuals with low income were more likely to report depression, and SPD was more common in older individuals and those with low levels of education. Suicidal ideation was high across all demographic factors, suggesting that a community-wide program to address suicide may be warranted.

Childhood violence and mental health among indigenous Sami and non-Sami populations in Norway: a SAMINOR 2 questionnaire study

The main objectives of this study were to investigate the association between childhood violence and psychological distress and post-traumatic stress symptoms (PTS) among Sami and non-Sami adults, and to explore a possible mediating effect of childhood violence on any ethnic differences in mental health. This study is part of a larger questionnaire survey on health and living conditions in Mid- and Northern Norway (SAMINOR 2) which included 2116 Sami and 8674 non-Sami participants. A positive association between childhood violence and psychological distress and PTS in adulthood was found regardless of ethnicity. For women, childhood violence may have mediated some of the ethnic differences in psychological distress (53.2%) and PTS (31.4%). A similar pattern was found for men as to psychological distress (45.5%) and PTS (55.5%). The prevalence of psychological distress was significantly higher in the Sami than in the non-Sami group: 15.8% vs. 13.0% for women, and 11.4% vs. 8.0% for men. Likewise, PTS showed a higher prevalence in the Sami group, both for women (16.2% vs. 12.4%) and for men (12.2% vs. 9.1).

CONCLUSION

A positive association between childhood violence and adult mental distress was found for both Sami and Norwegian adults. More mental problems were found among the Sami. Childhood violence may have mediated some of the ethnic differences.

Measuring and Understanding Food Insecurity in Australia: A Systematic Review

The number of Australians seeking food aid has increased in recent years; however, the current variability in the measurement of food insecurity means that the prevalence and severity of food insecurity in Australia is likely underreported. This is compounded by infrequent national health surveys that measure food insecurity, resulting in outdated population-level food insecurity data. This review sought to investigate the breadth of food insecurity research conducted in Australia to evaluate how this construct is being measured. A systematic review was conducted to collate the available Australian research. Fifty-seven publications were reviewed. Twenty-two used a single-item measure to examine food security status; 11 used the United States Department of Agriculture (USDA) Household Food Security Survey Module (HFSSM); two used the Radimer/Cornell instrument; one used the Household Food and Nutrition Security Survey (HFNSS); while the remainder used a less rigorous or unidentified method. A wide range in prevalence and severity of food insecurity in the community was reported; food insecurity ranged from 2% to 90%, depending on the measurement tool and population under investigation. Based on the findings of this review, the authors suggest that there needs to be greater consistency in measuring food insecurity, and that work is needed to create a measure of food insecurity tailored for the Australian context. Such a tool will allow researchers to gain a clear understanding of the prevalence of food insecurity in Australia to create better policy and practice responses.

Food Insecurity among Older Aboriginal and Torres Strait Islanders

It is well established that Indigenous populations are at a heightened risk of food insecurity. Yet, although populations (both Indigenous and non-Indigenous) are ageing, little is understood about the levels of food insecurity experienced by older Indigenous peoples. Using Australian data, this study examined the prevalence and correlates of food insecurity among older Aboriginal and Torres Strait Islanders. Using nationally representative data, we employed ordinal logistic regression models to investigate the association between socio-demographic characteristics and food insecurity. We found that 21% of the older Aboriginal and Torres Strait Islander population were food insecure, with 40% of this group exposed to food insecurity with food depletion and inadequate intake. This places this population at a 5 to 7-fold risk of experiencing food insecurity relative to their older non-Indigenous peers. Measures of geography, language and low socio-economic status were highly associated with exposure to food insecurity. Addressing food insecurity offers one pathway to reduce the disparity in health outcomes between Aboriginal and Torres Strait Islanders and non-Indigenous Australians. Policies that consider both remote and non-remote Australia, as well as those that involve Aboriginal people in their design and implementation are needed to reduce food insecurity.

Identifying evidence-practice gaps and strategies for improvement in Aboriginal and Torres Strait Islander maternal health care

Introduction

Adverse pregnancy outcomes are more common among Aboriginal and Torres Strait Islander populations than non-Indigenous populations in Australia. Later in life, most of the difference in life expectancy between Aboriginal and Torres Strait Islander women and non-Indigenous women is due to non-communicable diseases (NCDs). Most Aboriginal and Torres Strait Islander women attend health services regularly during pregnancy. Providing high-quality care within these appointments has an important role to play in improving the current and future health of women and babies.

Aim

This study engaged stakeholders in a theory-informed process to use aggregated continuous quality improvement (CQI) data to identify 1) priority evidence-practice gaps in Aboriginal and Torres Strait Islander maternal health care, 2) barriers and enablers to high-quality care, and 3) strategies to address identified priorities.

Methods

Three phases of reporting and feedback were implemented using de-identified CQI data from 91 health services between 2007 and 2014 (4,402 client records). Stakeholders (n = 172) from a range of professions and organisations participated.

Results

Stakeholders identified four priority areas relating to NCDs: smoking, alcohol, psychosocial wellbeing and nutrition. Barriers or enablers to high-quality care included workforce support, professional development, teamwork, woman-centred care, decision support, equipment and community engagement. Strategies to address the priorities included upskilling staff to provide best practice care in priority areas, advocating for availability of healthy food, housing and local referral options, partnering with communities on health promotion projects, systems to facilitate continuity of care and clear referral pathways.

Conclusions

This novel use of large-scale aggregate CQI data facilitated stakeholder input on priority evidence-practice gaps in maternal health care in Australia. Evidence-practice gaps relating to NCD risk factors and social determinants of health were prioritised, and stakeholders suggested both healthcare-focussed initiatives and approaches involving the community and the wider health sector. The findings can inform health service planning, advocacy, inter-agency strategies, and future research.

Psychological distress among Indigenous Australian cancer survivors

PURPOSE

The purpose of this study is to identify the level of and factors associated with distress in 155 Indigenous Australian cancer survivors approximately 6 months post-diagnosis.

METHODS

The distress thermometer (DT) was used to assess clinically significant distress (defined as having a DT score ≥ 4). Logistic regression was used to identify sociodemographic and clinical factors associated with clinically significant distress.

RESULTS

The mean distress score was 2.7 (SD 2.9), with about one in three Indigenous cancer survivors reporting clinically significant distress (35%; n = 54). After adjusting for age and sex, clinically significant distress was more likely among those who were separated/divorced/widowed than those who were married (odds ratio (OR) = 2.99, 95% confidence intervals (95% CI) 1.21-7.35, p = 0.017) and less likely among those residing in remote areas than those in major cities (OR = 0.23, 95% CI 0.08-0.71, p = 0.001) and in those receiving non-surgical treatment only compared with surgery only (OR = 0.24, 95% CI 0.08-0.68, p = 0.008).

CONCLUSIONS

Despite increased screening for distress in cancer care, this is, to our knowledge, the first published assessment of distress among Indigenous Australian cancer survivors. The characteristics of Indigenous cancer survivors associated with greater likelihood of clinically significant distress indicate at-risk subgroups who would benefit from screening and early intervention. Further research is required to identify the specific aetiologies of distress. Our findings indicate a need to identify psychological distress and for survivorship care to include culturally sensitive and tailored psychological support for Indigenous cancer survivors.

Mood and anxiety disorders in Australia and New Zealand's indigenous populations: A systematic review and meta-analysis

The Indigenous populations of Australia and New Zealand are considered at higher risk of mood and anxiety disorders but many studies do not include direct comparisons with similar non-Indigenous controls. We conducted a systematic search of relevant electronic databases, as well as snowballing and targeted searches of the grey literature. Studies were included for meta-analysis if they compared rates of mood and anxiety disorders between Indigenous and non-Indigenous Australians or Maori. Seven Australian and 10 NZ studies were included. Overall, Indigenous people in both countries did not have significantly higher rates of disorder. However, in terms of specific disorders, there were differences in risk by gender, country (Australia or NZ), disorder type, and prevalence (current, 12-month or lifetime). For instance, Indigenous Australians and Maori both had significantly lower rates of simple phobias (current prevalence) and Maori participants had significantly lower rates of both lifetime simple phobia and generalised anxiety disorders. By contrast, Indigenous Australians had significantly higher rates of bipolar affective disorder and social phobia (current prevalence). Generalisations regarding the risk of psychiatric disorders in Indigenous people cannot therefore be made as this varies by several factors. These include disorder type, sociodemographic factors, Indigenous origin and study method.

Social and Emotional Wellbeing Screening for Aboriginal and Torres Strait Islanders within Primary Health Care: A Series of Missed Opportunities?

BACKGROUND

Social and emotional wellbeing (SEWB) is a critical determinant of health outcomes for Indigenous Australians. This study examined the extent to which primary healthcare services (PHSs) undertake SEWB screening and management of Aboriginal and Torres Strait Islander clients, and the variation in SEWB screening and management across Indigenous PHS.

METHODS

Cross-sectional analysis between 2012 and 2014 of 3,407 Indigenous client records from a non-representative sample of 100 PHSs in 4 Australian states/territory was undertaken to examine variation in the documentation of: (1) SEWB screening using identified measurement instruments, (2) concern regarding SEWB, (3) actions in response to concern, and (4) follow up actions. Binary logistic regression was used to determine the factors associated with screening.

RESULTS

The largest variation in SEWB screening occurred at the state/territory level. The mean rate of screening across the sample was 26.6%, ranging from 13.7 to 37.1%. Variation was also related to PHS characteristics. A mean prevalence of identified SEWB concern was 13% across the sample, ranging from 9 to 45.1%. For the clients where SEWB concern was noted, 25.4% had no referral or PHS action recorded. Subsequent internal PHS follow up after 1 month occurred in 54.7% of cases; and six-monthly follow up of referrals to external services occurred in 50.9% of cases.

CONCLUSION

Our findings suggest that the lack of a clear model or set of guidelines on best practice for screening for SEWB in Indigenous health may contribute to the wide variation in SEWB service provision. The results tell a story of missed opportunities: 73.4% of clients were not screened and no further action was taken for 25.4% for whom an SEWB concern was identified. There was no follow up for just under half of those for whom action was taken. There is a need for the development of national best practice guidelines for SEWB screening and management, accompanied by dedicated SEWB funding, and training for health service providers as well as ongoing monitoring of adherence with the guidelines. Further research on barriers to screening and follow up actions is also warranted.

Social and emotional wellbeing assessment instruments for use with Indigenous Australians: A critical review

RATIONALE

There is growing recognition that in addition to universally recognised domains and indicators of wellbeing (such as population health and life expectancy), additional frameworks are required to fully explain and measure Indigenous wellbeing. In particular, Indigenous Australian wellbeing is largely determined by colonisation, historical trauma, grief, loss, and ongoing social marginalisation. Dominant mainstream indicators of wellbeing based on the biomedical model may therefore be inadequate and not entirely relevant in the Indigenous context. It is possible that "standard" wellbeing instruments fail to adequately assess indicators of health and wellbeing within societies that have a more holistic view of health.

OBJECTIVE

The aim of this critical review was to identify, document, and evaluate the use of social and emotional wellbeing measures within the Australian Indigenous community.

METHOD

The instruments were systematically described regarding their intrinsic properties (e.g., generic v. disease-specific, domains assessed, extent of cross-cultural adaptation and psychometric characteristics) and their purpose of utilisation in studies (e.g., study setting, intervention, clinical purpose or survey). We included 33 studies, in which 22 distinct instruments were used.

RESULTS

Three major categories of social and emotional wellbeing instruments were identified: unmodified standard instruments (10), cross-culturally adapted standard instruments (6), and Indigenous developed measures (6). Recommendations are made for researchers and practitioners who assess social and emotional wellbeing in Indigenous Australians, which may also be applicable to other minority groups where a more holistic framework of wellbeing is applied.

CONCLUSION

It is advised that standard instruments only be used if they have been subject to a formal cross-cultural adaptation process, and Indigenous developed measures continue to be developed, refined, and validated within a diverse range of research and clinical settings.

Life, lifestyle and location: examining the complexities of psychological distress in young adult Indigenous and non-Indigenous Australians

Mental health is fundamental to an individual’s health and well-being. Mental health disorders affect a substantial portion of the Australian population, with the most vulnerable time in adolescence and young adulthood. Indigenous Australians fare worse than other Australians on almost every measure of physical and mental health. Cross-sectional data from young adults (21–27 years) participating in the Life Course Program, Northern Territory, Australia, is presented. Rates of psychological distress were high in remote and urban residing Indigenous and urban non-Indigenous young adults. This rate was more pronounced in young women, particularly in Indigenous remote and urban residing women. Young adults with high psychological distress also had lower levels of positive well-being, higher perceived stress levels, experienced a higher number of major life events and were at an increased risk of suicidal ideation and/or self-harm. This study supports the need for a continued focus on early screening and treatment at this vulnerable age. The significant association seen between psychological distress and other markers of emotional well-being, particularly risk of suicidal ideation and/or self-harm, highlights the need for a holistic approach to mental health assessment and treatment. A concerted focus on improving the environs of young adults by lowering levels of stress, improving access to adequate housing, educational and employment opportunity, will assist in improving the emotional health of young adults.

Stressful events, social health issues and psychological distress in Aboriginal women having a baby in South Australia: implications for antenatal care

BACKGROUND

Around 6% of births in Australia are to Aboriginal and Torres Strait Islander families. Aboriginal and Torres Strait Islander women are 2-3 times more likely to experience adverse maternal and perinatal outcomes than non-Aboriginal women in Australia.

METHODS

Population-based study of mothers of Aboriginal babies born in South Australia, July 2011 to June 2013. Mothers completed a structured questionnaire at a mean of 7 months postpartum. The questionnaire included measures of stressful events and social health issues during pregnancy and maternal psychological distress assessed using the Kessler-5 scale.

RESULTS

Three hundred forty-four women took part in the study, with a mean age of 25 years (range 15-43). Over half (56.1%) experienced three or more social health issues during pregnancy; one in four (27%) experienced 5-12 issues. The six most commonly reported issues were: being upset by family arguments (55%), housing problems (43%), family member/friend passing away (41%), being scared by others people's behavior (31%), being pestered for money (31%) and having to leave home because of family arguments (27%). More than a third of women reporting three or more social health issues in pregnancy experienced high/very high postpartum psychological distress (35.6% versus 11.1% of women reporting no issues in pregnancy, Adjusted Odds Ratio = 5.4, 95% confidence interval 1.9-14.9).

CONCLUSIONS

The findings highlight unacceptably high rates of social health issues affecting Aboriginal women and families during pregnancy and high levels of associated postpartum psychological distress. In order to improve Aboriginal maternal and child health outcomes, there is an urgent need to combine high quality clinical care with a public health approach that gives priority to addressing modifiable social risk factors for poor health outcomes.

Allostatic load mediates the impact of stress and trauma on physical and mental health in Indigenous Australians

OBJECTIVES

A considerable gap exists in health and social emotional well-being between Indigenous people and non-Indigenous Australians. Recent research in stress neurobiology highlights biological pathways that link early adversity and traumas as well as life stresses to ill health. We argue that the neurobiological stress response and its maladaptive changes, termed allostatic load, provide a useful framework to understand how adversity leads to physical and mental illness in Indigenous people. In this paper we review the biology of allostatic load and make links between stress-induced systemic hormonal, metabolic and immunological changes and physical and mental illnesses.

CONCLUSIONS

Exposure to chronic stress throughout life results in an increased allostatic load that may contribute to a number of metabolic, cardiovascular and mental disorders that shorten life expectancy in Indigenous Australians.

Factors Affecting Indigenous West Australians' Health Behavior: Indigenous Perspectives

The factors driving the disparity in health outcomes between Indigenous and non-Indigenous Australians include socio-economic factors, racism, and history. The current study focused on exploring Indigenous participants' perspectives of the factors that affect the health behavior of their community members. Participatory action research methodology and a grounded theory approach were utilized. In total, 120 members of two urban West Australian Indigenous communities participated in focus group discussions. There was substantial similarity between the themes that emerged within the discussions held in the two communities. Factors relating to culture, social connections, racism, communication, and personal aspects were particularly salient to health behavior of the participants. Several of the themes including culture, racism, communication, and distrust highlight the tension caused by being a member of a minority cultural group that has been marginalized by the practices and attitudes of the dominant cultural group. Personal choice was sometimes prioritized over health.

Prevalence and incidence of dementia among indigenous populations: a systematic review

BACKGROUND

Indigenous populations may be at increased risk, compared with majority populations, for the development of dementia due to lower education levels and socio-economic status, higher rates of diabetes, hypertension, cardiovascular disease and alcohol abuse, an aging population structure, and poorer overall health. This is the first systematic review investigating the prevalence and incidence of dementia in indigenous populations worldwide.

METHODS

This systematic review was conducted in accordance with PRISMA guidelines. We searched MEDLINE, Embase, and PsycInfo for relevant papers published up to April 2015. Studies were included if they reported prevalence or incidence, the disease typically occurred after the age of 45, the study population included indigenous people, and the study was conducted in the general population.

RESULTS

Fifteen studies representing five countries (Canada, Australia, the USA, Guam, Brazil) met the inclusion criteria. Dementia prevalence ranged from 0.5% to 20%. Retrospective studies relying on medical records for diagnoses had much lower prevalence rates and a higher risk of bias than population-based prospective studies performing their own diagnoses with culturally appropriate cognitive assessment methods.

CONCLUSIONS

The prevalence of dementia among indigenous populations appears to be higher than it is for non-indigenous populations. Despite a building body of evidence supporting the need for dementia research among indigenous populations, there is a paucity of epidemiological research, none of which is of high quality.

Factors Influencing the Health Behaviour of Indigenous Australians: Perspectives from Support People

Disparities between the health of Indigenous and non-Indigenous populations continue to be prevalent within Australia. Research suggests that Indigenous people participate in health risk behaviour more often than their non-Indigenous counterparts, and that such behaviour has a substantial impact on health outcomes. Although this would indicate that reducing health risk behaviour may have positive effects on health outcomes, the factors that influence Indigenous health behaviour are still poorly understood. This study aimed to interview people who support Indigenous groups to gain an understanding of their views on the factors influencing health behaviour within Indigenous groups in Western Australia. Twenty nine people participated in the study. The emergent themes were mapped against the social ecological model. The results indicated that: (1) culture, social networks, history, racism, socioeconomic disadvantage, and the psychological distress associated with some of these factors interact to affect health behaviour in a complex manner; (2) the desire to retain cultural identity and distinctiveness may have both positive and negative influence on health risk behaviour; (3) strong social connections to family and kin that is intensified by cultural obligations, appears to affirm and disrupt positive health behaviour; (4) the separation between Indigenous and non-Indigenous social connection/networks that appeared to be fostered by marginalisation and racism may influence the effect of social networks on health behaviour; and (5) communication between Indigenous and non-Indigenous people may be interrupted by distrust between the groups, which reduces the influence of some non-Indigenous sources on the health behaviour of Indigenous people.

Developing a best practice pathway to support improvements in Indigenous Australians' mental health and well-being: a qualitative study

OBJECTIVE

There is a need to adapt pathways to care to promote access to mental health services for Indigenous people in Australia. This study explored Indigenous community and service provider perspectives of well-being and ways to promote access to care for Indigenous people at risk of depressive illness.

DESIGN

A participatory action research framework was used to inform the development of an agreed early intervention pathway; thematic analysis

SETTING

2 remote communities in the Northern Territory.

PARTICIPANTS

Using snowball and purposive sampling, 27 service providers and community members with knowledge of the local context and the diverse needs of those at risk of depression were interviewed. 30% of participants were Indigenous. The proposed pathway to care was adapted in response to participant feedback.

RESULTS

The study found that Indigenous mental health and well-being is perceived as multifaceted and strongly linked to cultural identity. It also confirms that there is broad support for promotion of a clear pathway to early intervention. Key identified components of this pathway were the health centre, visiting and community-based services, and local community resources including elders, cultural activities and families. Enablers to early intervention were reported. Significant barriers to the detection and treatment of those at risk of depression were identified, including insufficient resources, negative attitudes and stigma, and limited awareness of support options.

CONCLUSIONS

Successful early intervention for well-being concerns requires improved understanding of Indigenous well-being perspectives and a systematic change in service delivery that promotes integration, flexibility and collaboration between services and the community, and recognises the importance of social determinants in health promotion and the healing process. Such changes require policy support, targeted training and education, and ongoing promotion.

Mental health and substance use in an urban First Nations population in Hamilton, Ontario

OBJECTIVES

Mental health and substance use have been identified as health priorities currently facing Indigenous peoples in Canada; however, accessible and culturally relevant population health data for this group are almost non-existent. The aim of the Our Health Counts study was to generate First Nations adult population health data in partnership with the De dwa da dehs ney&gt;s Aboriginal Health Access Centre in Hamilton, Ontario.

METHODS

Analysis involved data gathered through respondent-driven sampling. Prevalence estimates and 95% confidence intervals were generated for diagnosis and treatment of a psychological disorder or mental illness, depression, anxiety, post-traumatic stress disorder (PTSD) and suicide, alcohol and substance use, and access to emotional support.

RESULTS

Of the 554 First Nations adults who participated in the Our Health Counts study in Hamilton, 42% had been told by a health care worker that they had a psychological and/or mental health disorder. High rates of depression (39%) and PTSD (34%), as well as suicide ideation (41%) and attempts (51%) were reported. Half of the sample reported marijuana use in the previous 12 months, and 19% reported the use of cocaine and opiates.

CONCLUSION

First Nations adults living in Hamilton experience a disproportionate burden of mental health and addictions. By working in partnership with urban Aboriginal organizations, it is possible to produce policy- and service-relevant data and address the current deficiency in appropriate mental health and substance use services for urban Aboriginal people.

A systematic review: Identifying the prevalence rates of psychiatric disorder in Australia's Indigenous populations

OBJECTIVE

This review aimed to draw on published literature to identify the prevalence rates of psychiatric disorders in Australia's Indigenous populations, Aboriginal and Torres Strait Islander peoples.

METHOD

A systematic review following the Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) model was conducted using the following electronic databases: PubMed, Scopus, Web of Science, MEDLINE, PsycINFO, PsycARTICLES, and Informit Indigenous and Health Collections. Studies were included for analysis if they were empirical quantitative studies reporting prevalence rates for any psychiatric disorder in Indigenous people.

RESULTS

Of the 1584 papers extracted by the search strategy, 17 articles met the eligibility criteria and were reviewed in detail. Methodology, sampling strategy and study design varied greatly across these 17 studies. Prevalence rates varied by disorder and are as follows: major depressive disorder (4.3-51%); mood disorders (7.7-43.1%); post-traumatic stress disorder (14.2-55.2%); anxiety disorders (17.2-58.6%); substance dependence (5.9%-66.2%); alcohol dependence (21.4-55.4%); and psychotic disorders (1.68-25%). While the number of studies on community-based Indigenous populations was limited, available evidence suggested that prevalence rates are higher in prison populations compared with community-based studies.

CONCLUSIONS

It was identified that there is limited evidence on the occurrence of psychiatric disorders for Indigenous people in the general community. More research in this area is essential to provide accurate and reliable estimates and to provide a baseline for evaluating the effectiveness of programs aimed at reducing the high mental health burden experienced by Indigenous Australians. Future research needs to ensure that standardised and validated methods are used to accurately estimate the prevalence of psychiatric disorders among Indigenous Australians.

Social determinants and psychological distress among Aboriginal and Torres Strait islander adults in the Australian state of Victoria: a cross-sectional population based study

Aboriginal and Torres Strait Islander adults in the Australian state of Victoria have a higher prevalence of psychological distress than their non-Aboriginal and Torres Strait Islander counterparts. We sought to explain this inequality, focussing on the social determinants of health. We used population-based survey data from the 2008 Victorian Population Health Survey; a cross-sectional landline computer-assisted telephone survey of 34,168 randomly selected adults. We defined psychological distress as a score of 22 or more on the Kessler 10 Psychological Distress scale. We used logistic regression to identify socio-demographic characteristics and social capital indicators that were associated with psychological distress. We then created multivariable models to explore the association between psychological distress and Aboriginal and Torres Strait Islander status that incorporated all significant socioeconomic status (SES) and social capital variables, adjusting for all non-SES socio-demographic characteristics. Aboriginal and Torres Strait Islander Victorians (24.5%) were more than twice as likely than their non-Aboriginal and Torres Strait Islander counterparts (11.3%) to have psychological distress (odds ratio (OR) = 2.56, 95% confidence interval; 1.67-3.93). Controlling for SES, negative perceptions of the residential neighbourhood, lack of social support from family, social and civic distrust, and all non-SES socio-demographic variables (age, sex, marital status, household composition, and rurality), rendered the previously statistically significant inequality in the prevalence of psychological distress, between Aboriginal and Torres Strait Islander Victorians and their non-Aboriginal and Torres Strait Islander counterparts, insignificant at the p = 0.05 level (OR = 1.50; 0.97-2.32). Psychological distress is an important health risk factor for Aboriginal and Torres Strait Islander adults that has yet to be widely acknowledged and addressed. Addressing the underlying inequalities in SES and social capital may be the key to addressing the inequality in psychological distress.

Clinical use of the Kessler psychological distress scales with culturally diverse groups

The Kessler 10 (K10) and embedded Kessler 6 (K6) was developed to screen for non-specific psychological distress and serious mental illness in mental health surveys of English-speaking populations, but has been adopted in Western and non-Western countries as a screening and outcome measure in primary care and mental health settings. This review examines whether the original K6/K10's validity for culturally diverse populations was established, and whether the cultural equivalence, and sensitivity to change of translated or culturally adapted K6/K10s, has been demonstrated with culturally diverse client groups. Evidence for the original K6/K10's validity for culturally diverse populations is limited. Questions about the conceptual and linguistic equivalence of translated/adapted K6/K10s arise from reports of changes in item connotation and differential item functioning. Evidence for structural equivalence is inconsistent, as is support for criterion equivalence, with the majority of studies compromising on accuracy in case prediction. Research demonstrating sensitivity to change with culturally diverse groups is lacking. Inconsistent evidence for the K6/K10's cultural appropriateness in clinical settings, and a lack of clinical norms for either majority or culturally diverse groups, indicate the importance of further research into the psychological distress construct with culturally diverse clients, and the need for caution in interpreting K6/K10 scores.

Psychological distress and comorbid physical conditions: disease or disability?

BACKGROUND

The relationship between comorbidity and psychological distress is well documented, however the mechanism of this association is unclear. We aim to assess the extent to which the association between common chronic conditions and high scores on the Kessler Psychological Distress Scale (K10) measure of psychological distress vary according to comorbid conditions, disability, and sociodemographic circumstances.

METHODS

Analysis of self-reported cross-sectional data from the New South Wales 45 and Up Study, Australia, for 236,508 participants aged 45 years and over, using logistic regression modeling.

RESULTS

Self-reported heart attack/angina, other heart disease, stroke, and diabetes were all significantly associated with higher risk of high/very high K10 scores. These associations were attenuated, but remained statistically significant, when comorbidity, disability, and sociodemographic factors were added to the model. Men reporting needing help for daily tasks were nine times as likely to report high/very high K10 scores as those without this need, and women reporting needing help were seven times more likely to have high/very high K10 scores.

CONCLUSIONS

Heart attack/angina, other heart disease, stroke, and diabetes are all significantly associated with psychological distress. However, these effects are partly explained by other comorbid conditions, limitations on physical functioning, and sociodemographic factors. These findings highlight the importance of developing public health policies that encompass psychological, physiological, and social domains, and provide crucial insights for clinicians in identifying and supporting those people at risk of psychological distress.

Tailoring a family-based alcohol intervention for Aboriginal Australians, and the experiences and perceptions of health care providers trained in its delivery

BACKGROUND

Aboriginal Australians experience a disproportionately high burden of alcohol-related harm compared to the general Australian population. Alcohol treatment approaches that simultaneously target individuals and families offer considerable potential to reduce these harms if they can be successfully tailored for routine delivery to Aboriginal Australians. The Community Reinforcement Approach (CRA) and Community Reinforcement and Family Training (CRAFT) are two related interventions that are consistent with Aboriginal Australians' notions of health and wellbeing. This paper aims to describe the process of tailoring CRA and CRAFT for delivery to Aboriginal Australians, explore the perceptions of health care providers participating in the tailoring process, and their experiences of participating in CRA and CRAFT counsellor certification.

METHODS

Data sources included notes recorded from eight working group meetings with 22 health care providers of a drug and alcohol treatment agency and Aboriginal Community Controlled Health Service (November 2009-February 2013), and transcripts of semi-structured interviews with seven health care providers participating in CRA and CRAFT counsellor certification (May 2012). Qualitative content analysis was used to categorise working group meeting notes and interview transcripts were into key themes.

RESULTS

Modifying technical language, reducing the number of treatment sessions, and including an option for treatment of clients in groups, were key recommendations by health care providers for improving the feasibility and applicability of delivering CRA and CRAFT to Aboriginal Australians. Health care providers perceived counsellor certification to be beneficial for developing their skills and confidence in delivering CRA and CRAFT, but identified time constraints and competing tasks as key challenges.

CONCLUSIONS

The tailoring process resulted in Aboriginal Australian-specific CRA and CRAFT resources. The process also resulted in the training and certification of health care providers in CRA and CRAFT and the establishment of a local training and certification program.
