Protocol for the process evaluation of a complex intervention delivered in schools to prevent adolescent depression: the Future Proofing Study

INTRODUCTION

Process evaluations provide insight into how interventions are delivered across varying contexts and why interventions work in some contexts and not in others. This manuscript outlines the protocol for a process evaluation embedded in a cluster randomised trial of a digital depression prevention intervention delivered to secondary school students (the Future Proofing Study). The purpose is to describe the methods that will be used to capture process evaluation data within this trial.

METHODS AND ANALYSIS

Using a hybrid type 1 design, a mixed-methods approach will be used with data collected in the intervention arm of the Future Proofing Study. Data collection methods will include semistructured interviews with school staff and study facilitators, automatically collected intervention usage data and participant questionnaires (completed by school staff, school counsellors, study facilitators and students). Information will be collected about: (1) how the intervention was implemented in schools, including fidelity; (2) school contextual factors and their association with intervention reach, uptake and acceptability; (3) how school staff, study facilitators and students responded to delivering or completing the intervention. How these factors relate to trial effectiveness outcomes will also be assessed. Overall synthesis of the data will provide school cluster-level and individual-level process outcomes.

ETHICS AND DISSEMINATION

Ethics approval was obtained from the University of New South Wales (NSW) Human Research Ethics Committee (HC180836; 21st January 2019) and the NSW Government State Education Research Applications Process (SERAP 2019201; 19th August 2019). Results will be submitted for publication in peer-reviewed journals and discussed at conferences. Our process evaluation will contextualise the trial findings with respect to how the intervention may have worked in some schools but not in others. This evaluation will inform the development of a model for rolling out digital interventions for the prevention of mental illness in schools.

Developing and validating measures of self-reported everyday and healthcare discrimination for Aboriginal and Torres Strait Islander adults

BACKGROUND

It is well established that racism is a fundamental contributor to poor health and inequities. There is consistent evidence of high exposure to discrimination among Aboriginal and Torres Strait Islander (Indigenous Australian) peoples, but impacts have not been fully quantified, in part due to limited measurement tools. We aim to validate instruments developed to measure interpersonal discrimination.

METHODS

Instruments were discussed at five focus groups and with experts, and field tested in developing Mayi Kuwayu: The National Study of Aboriginal and Torres Strait Islander Wellbeing. Data from 7501 baseline survey participants were analysed. Acceptability was assessed according to extent of missingness, construct validity using exploratory and confirmatory factor analysis, and reliability using Cronbach's alpha. Associations between each instrument and outcomes conceptually understood to be closely (community-level racism) or less closely (family wellbeing) related were quantified to test convergent and discriminant validity.

RESULTS

An 8-item instrument captures experiences of discrimination in everyday life and a 4-item instrument experiences in healthcare, each followed by a global attribution item. Item missingness was 2.2-3.7%. Half (55.4%) of participants reported experiencing any everyday discrimination, with 65.7% attributing the discrimination to Indigeneity; healthcare discrimination figures were 34.1% and 51.1%. Items were consistent with two distinct instruments, differentiating respondents with varying experiences of discrimination. Scales demonstrated very good reliability and convergent and divergent validity.

CONCLUSION

These brief instruments demonstrate face validity and robust psychometric properties in measuring Aboriginal and Torres Strait Islander adults' experiences of interpersonal discrimination in everyday life and in healthcare. They can be used to quantify population-level experiences of discrimination, and associated wellbeing consequences, and monitor change.

Development and psychometric properties of the Functioning and Recovery Scale: a new measure to assess psychosocial functioning after a suicide attempt

OBJECTIVE

Few measures have been developed to assess the efficacy of community-based suicide prevention and recovery services. The current study aimed to develop a scale to provide accurate assessment and monitoring of functional recovery for people following a recent suicide attempt at The Way Back Support Service in Australia.

METHOD

The study was conducted in multiple iterative stages: (1) literature review to identify existing scales; (2) structured informant interview with people with lived experience of a suicide attempt; (3) expert survey of researchers, clinicians, and people with lived experience on relevance and acceptability of candidate items; and (4) quantitative survey of the pilot scale to assess psychometric properties.

RESULTS

An 11-item scale assessing recovery in people who have recently attempted suicide was demonstrated to be a unidimensional measure with sound psychometric properties (α = 0.94). The scale was highly acceptable to researchers, clinicians, and people with lived experience. A short-form 6-item scale was also developed.

CONCLUSIONS

The Functioning and Recovery Scale is likely to be useful for evaluating suicide prevention programs. No existing scale captures the broad construct of psychosocial functioning with sound psychometric rigor and the involvement of people with lived experience of suicide attempt.

Consumer-Guided Development of an Engagement-Facilitation Intervention for Increasing Uptake and Adherence for Self-Guided Web-Based Mental Health Programs: Focus Groups and Online Evaluation Survey

Background

Self-guided web-based mental health programs are effective in treating and preventing mental health problems. However, current engagement with these programs in the community is suboptimal, and there is limited evidence indicating how to increase the use of existing evidence-based programs.

Objective

This study aims to investigate the views of people with lived experience of depression and anxiety on factors influencing their engagement with self-guided web-based mental health (e–mental health) programs and to use these perspectives to develop an engagement-facilitation intervention (EFI) to increase engagement (defined as both uptake and adherence) with these programs.

Methods

A total of 24 community members (female=21; male=3) with lived experience of depression and anxiety or depression or anxiety alone participated in 1 of 4 focus groups discussing the factors influencing their engagement with self-guided e–mental health programs and the appearance, delivery mode, and functionality of content for the proposed EFI. A subsequent evaluation survey of the focus group participants (n=14) was conducted to evaluate the resultant draft EFI. Data were thematically analyzed using both inductive and deductive qualitative methods.

Results

Participants suggested that the critical component of an EFI was information that would challenge personal barriers to engagement, including receiving personalized symptom feedback, information regarding the program’s content or effectiveness and data security, and normalization of using e–mental health programs (eg, testimonials). Reminders, rewards, feedback about progress, and coaching were all mentioned as facilitating adherence.

Conclusions

EFIs have the potential to improve community uptake of e–mental health programs. They should focus on providing information on the content and effectiveness of e–mental health programs and normalizing their use. Given that the sample comprised predominantly young females, this study may not be generalizable to other population groups. There is a strong value in involving people with a lived experience in the design and development of EFIs to maximize their effectiveness.

The Effect of COVID-19 on Mental Health and Wellbeing in a Representative Sample of Australian Adults

There is minimal knowledge about the impact of large-scale epidemics on community mental health, particularly during the acute phase. This gap in knowledge means we are critically ill-equipped to support communities as they face the unprecedented COVID-19 pandemic. This study aimed to provide data urgently needed to inform government policy and resource allocation now and in other future crises. The study was the first to survey a representative sample from the Australian population at the early acute phase of the COVID-19 pandemic. Depression, anxiety, and psychological wellbeing were measured with well-validated scales (PHQ-9, GAD-7, WHO-5). Using linear regression, we tested for associations between mental health and exposure to COVID-19, impacts of COVID-19 on work and social functioning, and socio-demographic factors. Depression and anxiety symptoms were substantively elevated relative to usual population data, including for individuals with no existing mental health diagnosis. Exposure to COVID-19 had minimal association with mental health outcomes. Recent exposure to the Australian bushfires was also unrelated to depression and anxiety, although bushfire smoke exposure correlated with reduced psychological wellbeing. In contrast, pandemic-induced impairments in work and social functioning were strongly associated with elevated depression and anxiety symptoms, as well as decreased psychological wellbeing. Financial distress due to the pandemic, rather than job loss per se, was also a key correlate of poorer mental health. These findings suggest that minimizing disruption to work and social functioning, and increasing access to mental health services in the community, are important policy goals to minimize pandemic-related impacts on mental health and wellbeing. Innovative and creative strategies are needed to meet these community needs while continuing to enact vital public health strategies to control the spread of COVID-19.

The psychometric properties of 30-day versions of the DSM-5 dimensional severity scales for social anxiety disorder and panic disorder

OBJECTIVES

The current study aimed to investigate the psychometric properties of the DSM-5 dimensional severity scales for social anxiety disorder (SAD) and panic disorder (PD) using a past 30 day timeframe.

METHODS

Data were from a sample of 1,052 Australian community dwelling adults (aged 18 years or older) recruited using online advertisements. Respondents completed the DSM-5 severity scales for SAD and PD as well as a range of additional widely used self-administered scales for SAD and PD in the past 30 days prior to the survey.

RESULTS

Both scales exhibited high internal consistency (alpha>=0.94) and a strong general factor that justified unidimensional item response analysis (OmegaH=0.96). There was no evidence of significant local dependence amongst item pairs after accounting for the single factor. Similarly, there was no evidence for meaningful differential item functioning of the scales across sex, age, education level, and residential location. There was high convergent validity (0.71 - 0.85) amongst conceptually related scale and moderate to high correlations (0.54 - 0.80) between conceptually unrelated scales.

CONCLUSIONS

These findings provide support for the use of past month versions of the DSM-5 severity scales for SAD and PD by researchers and clinicians to inform and supplement diagnostic decisions.

Study protocol for a mixed methods prospective cohort study to explore experiences of care following a suicidal crisis in the Australian healthcare system

INTRODUCTION

For individuals presenting to the emergency department (ED) for a suicide attempt, the period after discharge from hospital is marked by heightened vulnerability for further suicide attempts. Effective care following a suicidal crisis has the potential to significantly decrease this risk. The current study aims to examine the impact of the LifeSpan multilevel suicide prevention model on experiences of care following a suicidal crisis. Perspectives from healthcare consumers (individuals who have presented to the ED following a suicidal crisis), carers, and health professionals will be explored. The LifeSpan model is currently being evaluated as a high-fidelity trial in four geographically defined regions in New South Wales, Australia.

METHODS AND ANALYSIS

This study will use a mixed methods prospective cohort design. Quantitative data collection includes a structured survey, administered to healthcare consumers from LifeSpan sites and control sites. Two cohorts of healthcare consumers will be recruited 12 months apart with baseline assessment occurring within 18 months of the ED presentation, and follow-up 12 months after the initial assessment. Survey participants will be recruited online and through participating EDs, mental health organisations and aftercare services. Qualitative interview data from healthcare consumers, carers who have accompanied a loved one to the ED following a suicidal crisis and health professionals who provide care to people at risk of suicide will be collected concurrently with the recruitment of the first cohort of survey participants. Purposive and convenience sampling techniques will be used for recruitment of interview participants. The primary outcome for this study will be healthcare consumers' experiences of service provided at the ED. Analysis will be undertaken of the change over time within LifeSpan sites, as well as between LifeSpan sites and control sites, using mixed effects repeated measures models as principal means of data analysis.

ETHICS AND DISSEMINATION

This research has been approved by the Hunter New England Human Research Ethics Committee (HREC/17/HNE/144). Results will be disseminated via conferences and peer-reviewed journals.

A randomised controlled trial of a relationship-focussed mobile phone application for improving adolescents' mental health

BACKGROUND

This study evaluated the acceptability and effectiveness of a relationship-focussed mobile phone application (WeClick) for improving depressive symptoms and other mental health outcomes in adolescents.

METHODS

A randomised controlled trial involving 193 youth (M age: 14.82, SD: 0.94, 86.5% female) from Australia was conducted. Youth were recruited via the Internet and randomly allocated to the intervention or a 4-week wait list control condition, stratified for age and gender. The primary outcome was change in depressive symptom scores measured using the Patient Health Questionnaire for Adolescents (PHQ-A) at baseline, 4-week post-test and 12-week follow-up. Secondary outcomes included anxiety, psychological distress, wellbeing, help-seeking intentions for mental health, social self-efficacy and social support. Participants in the intervention condition received access to the intervention for four weeks. Thematic analysis was utilised to identify and examine acceptability.

RESULTS

The change in PHQ-A scores from baseline to 4-week post-test did not differ significantly (d = 0.26, p = .138) between the intervention (Mchange = -2.9, SD = 5.3) and wait list control conditions (Mchange = -1.7, SD = 4.3). However, significant between-group improvements were observed in wellbeing (d = 0.37, p = .023), help-seeking intentions (d = 0.36, p = .016) and professional help-seeking intentions for mental health problems (d = 0.36, p = .008). Increases in help-seeking intentions were sustained at follow-up in the intervention condition. No differential effects were found for generalised anxiety, separation anxiety, social self-efficacy or for any social support outcomes. Over 90% of participants indicated the app was enjoyable, interesting and easy to use. The app provided 'advice and direction' (n = 42; 46.15%), an 'opportunity for self-reflection' (n = 33; 36.3%) and 'normalised experiences' (n = 21; 23.1%).

CONCLUSIONS

The WeClick app was found to be effective for improving wellbeing and help-seeking intentions for mental health in adolescents. A larger, adequately powered trial is now required to establish differential effects on depressive symptoms. This trial was registered with the Australian New Zealand Clinical Trials Registry (ANZCTR): ACTRN12618001982202.

Development of the RMT20, a composite screener to identify common mental disorders

BACKGROUND

There are few very brief measures that accurately identify multiple common mental disorders.

AIMS

The aim of this study was to develop and assess the psychometric properties of a new composite measure to screen for five common mental disorders.

METHOD

Two cross-sectional psychometric surveys were used to develop (n = 3175) and validate (n = 3620) the new measure, the Rapid Measurement Toolkit-20 (RMT20) against diagnostic criteria. The RMT20 was tested against a DSM-5 clinical checklist for major depression, generalised anxiety disorder, panic disorder, social anxiety disorder and post-traumatic stress disorder, with comparison with two measures of general psychological distress: the Kessler-10 and Distress Questionnaire-5.

RESULTS

The area under the curve for the RMT20 was significantly greater than for the distress measures, ranging from 0.86 to 0.92 across the five disorders. Sensitivity and specificity at prescribed cut-points were excellent, with sensitivity ranging from 0.85 to 0.93 and specificity ranging from 0.73 to 0.83 across the five disorders.

CONCLUSIONS

The RMT20 outperformed two established scales assessing general psychological distress, is free to use and has low respondent burden. The measure is well-suited to clinical screening, internet-based screening and large-scale epidemiological surveys.

Ethical issues and practical barriers in internet-based suicide prevention research: a review and investigator survey

BACKGROUND

People who are at elevated risk of suicide stand to benefit from internet-based interventions; however, research in this area is likely impacted by a range of ethical and practical challenges. The aim of this study was to examine the ethical issues and practical barriers associated with clinical studies of internet-based interventions for suicide prevention.

METHOD

This was a mixed-methods study involving two phases. First, a systematic search was conducted to identify studies evaluating internet-based interventions for people at risk of suicide, and information pertaining to safety protocols and exclusion criteria was extracted. Second, investigators on the included studies were invited to complete an online survey comprising open-ended and forced-choice responses. Quantitative and qualitative methods were used to analyse the data.

RESULTS

The literature search identified 18 eligible studies, of which three excluded participants based on severity of suicide risk. Half of the 15 suicide researchers who participated in the survey had experienced problems obtaining ethics approval, and none had encountered adverse events attributed to their intervention. Survey respondents noted the difficulty of managing risk in online environments and the limitations associated with implementing safety protocols, although some also reported increased confidence resulting from the ethical review process. Respondents recommended researchers pursue a collaborative relationship with their research ethics committees.

CONCLUSION

There is a balance to be achieved between the need to minimise the risk of adverse events whilst also ensuring interventions are being validated on populations who may be most likely to use and benefit from them (i.e., those who prefer anonymity). Further research is required to obtain the views of research ethics committees and research participants on these issues. Dialogue between researchers and ethics committees is necessary to address the need to ensure safety while also advancing the timely development of effective interventions in this critical area.

Protocol for a stepped-wedge, cluster randomized controlled trial of the LifeSpan suicide prevention trial in four communities in New South Wales, Australia

BACKGROUND

Despite increasing investment in suicide prevention, Australian suicide rates have increased steadily in the past decade. In response to growing evidence for multicomponent intervention models for reducing suicide, the LifeSpan model has been developed as the first multicomponent, evidence-based, system-wide approach to suicide prevention in Australia. The LifeSpan model consists of nine evidence-based strategies. These include indicated, selective and universal interventions which are delivered simultaneously to community and healthcare systems over a 2-year implementation period. This study will evaluate the effectiveness of the LifeSpan model in reducing suicide attempts and suicide deaths in four geographically defined regions in New South Wales, Australia.

METHODS

We outline the protocol for a stepped-wedge, cluster randomized controlled trial. Following a 6-month transition phase, the trial sites will move to the 2-year active implementation phase in 4-monthly intervals with evaluation extending a minimum of 24 months after establishment of the full active period. Analysis will be undertaken of the change attributable to the invention across the four sites. The primary outcome for the study is the rate of attempted suicide in the regions involved. Rate of suicide deaths within each site is a secondary outcome.

DISCUSSION

If proven effective, the LifeSpan model for suicide prevention could be more widely delivered in Australian communities, providing a valuable new approach to tackle rising suicide rates. LifeSpan has the potential to significantly contribute to the mental health of Australians by improving help-seeking for suicide, facilitating early detection, and improving aftercare to reduce re-attempts. The findings from this research should also contribute to the evidence base for multilevel suicide prevention programs internationally.

Factors associated with engagement in online self-help programs among people with suicidal thoughts

BACKGROUND

The effectiveness of internet-based self-help programs for mental health may be limited by low engagement. Identifying factors associated with engagement in online interventions assists in developing strategies to improve efficacy through greater engagement. The aim of the current study was to identify factors associated with engagement among people with suicidal thoughts who completed an online program.

METHOD

418 adults with suicidal ideation were recruited online into a randomized controlled trial of a 6-week internet-based self-help program. Program usage for the intervention and active control conditions was measured as the number of logins and modules accessed. Predictors of program usage and between-group differences were examined, including sociodemographic variables, user preferences and mental health status.

RESULTS

Both the control group and the intervention group accessed approximately three modules (M = 3.1, SD = 2.0 v. M = 2.8, SD = 2.1, respectively), although participants in the intervention group had a significantly higher number of logins (17.3 vs 9.7, p < 0.001). Across both conditions, individuals with more severe suicidal thoughts had better engagement with their respective program. More logins for both programs were also associated with being female, married or in a de-facto relationship, not employed, less severe depression and less willingness to seek help from informal sources.

LIMITATIONS

Metrics of adherence may not directly reflect engagement with the program. There may be additional unmeasured factors associated with engagement.

CONCLUSIONS

The findings suggest that different engagement strategies may be required depending on sociodemographic and clinical characteristics. Tailoring interventions to at-risk subgroups may optimise health and functional outcomes.

Self-reported disability and quality of life in an online Australian community sample with suicidal thoughts

BACKGROUND

Limited research has been conducted to quantify the level of disability and health related quality of life (HRQoL) associated with suicidal thoughts and behaviour. The aims of the current study were to (1) describe levels of disability and HRQoL in an Australian sample of adults with suicidal ideation, (2) examine the effect of zero, one, or more than one previous suicide attempt on disability and HRQoL, and (3) describe the demographic and clinical characteristics associated with disability and HRQoL.

METHOD

Data for the current study is drawn from the baseline assessment of the Healthy Thinking trial that evaluated the effectiveness of an online self-help program for suicidal thoughts in an Australian adult community sample (n = 418). Measures of disability, quality of life, clinical symptoms, suicidality and demographic variables were included.

RESULTS

The mean disability score for the overall sample was 19.2 (SD = =8.9), while the mean perceived physical health score was 40.7 (SD = =6.5) and the mean perceived mental health score was 36.1 (SD = =5.9). Higher levels of disability and lower levels of perceived physical health were associated with multiple suicide attempts compared to one or no history of suicide attempt.

LIMITATIONS

Limitations included the limited generalisability of results, the use of self-report to assess suicide attempts, and the use of cross-sectional data.

CONCLUSION

Suicidal thoughts and behaviours are associated with high levels disability and low levels of perceived physical and mental health. Early intervention programs are needed to reduce the high levels of burden associated with suicidality.

Development and Validation of Static and Adaptive Screeners to Assess Suicidal Thoughts and Behavior

OBJECTIVE

The aim of the current study was to use a 23-item bank of self-reported symptoms of suicidal thoughts and behaviors to develop new brief measures of suicide risk using data-driven methods. Collectively referred to as the Rapid Measurement Toolkit for Suicidality (RMTS), the new brief static and adaptive measures would allow more efficient screening for suicide risk in clinical and research settings.

METHOD

Data for the current study consist of 3,175 Australian adults who form the development sample and 3,755 Australian adults who form the validation sample. Both samples were independently recruited online using Facebook advertisements. Item response theory (IRT) was applied to the 23-item suicide item bank to develop a brief static dimensional measure and to simulate various computerized adaptive algorithms.

RESULTS

A 5-item brief static dimensional screener was developed, which performed as well as the commonly used Suicidal Behaviors Questionnaire-Revised (SBQ-R), with marginally greater sensitivity and more information across the continuum of suicidality. An adaptive screener required a mean of 6.2 items and correlated 0.98 with the full item bank.

CONCLUSIONS

The RMTS provides reliable and valid brief static and adaptive screeners for the measurement of suicide risk in community, research, and clinical settings.

The role of maladaptive personality domains across multiple levels of the HiTOP structure

This study aimed to examine associations between maladaptive personality traits and psychopathology from the perspective of the hierarchical taxonomy of psychopathology (HiTOP). We tested hierarchical structural models to further validate a portion of the structural components of HiTOP. We also tested a priori personality and psychopathology associations with three levels of the HiTOP hierarchy: general psychopathology, spectra and syndromes/disorders. We used a large sample from the general Australian population who completed a large set of personality and psychopathology inventories online. Confirmatory factor analyses indicated that internalizing, externalizing and thought dysfunction spectra emerged structurally, as expected per HiTOP, but also revealed that obsessive-compulsive disorder loaded on both internalizing and thought dysfunction and attention deficit hyperactivity disorder on both externalizing and internalizing. Furthermore, results indicated that almost all personality and psychopathology hypotheses were supported, although trait antagonism did not predict externalizing to the degree initially expected. Implications for personality and psychopathology are discussed. © 2019 John Wiley & Sons, Ltd.

A trial protocol for the effectiveness of digital interventions for preventing depression in adolescents: The Future Proofing Study

BACKGROUND

Depression frequently first emerges during adolescence, and one in five young people will experience an episode of depression by the age of 18 years. Despite advances in treatment, there has been limited progress in addressing the burden at a population level. Accordingly, there has been growing interest in prevention approaches as an additional pathway to address depression. Depression can be prevented using evidence-based psychological programmes. However, barriers to implementing and accessing these programmes remain, typically reflecting a requirement for delivery by clinical experts and high associated delivery costs. Digital technologies, specifically smartphones, are now considered a key strategy to overcome the barriers inhibiting access to mental health programmes. The Future Proofing Study is a large-scale school-based trial investigating whether cognitive behaviour therapies (CBT) delivered by smartphone application can prevent depression.

METHODS

A randomised controlled trial targeting up to 10,000 Year 8 Australian secondary school students will be conducted. In Stage I, schools will be randomised at the cluster level either to receive the CBT intervention app (SPARX) or to a non-active control group comparator. The primary outcome will be symptoms of depression, and secondary outcomes include psychological distress, anxiety and insomnia. At the 12-month follow-up, participants in the intervention arm with elevated depressive symptoms will participate in an individual-level randomised controlled trial (Stage II) and be randomised to receive a second CBT app which targets sleep difficulties (Sleep Ninja) or a control condition. Assessments will occur post intervention (both trial stages) and at 6, 12, 24, 36, 48 and 60 months post baseline. Primary analyses will use an intention-to-treat approach and compare changes in symptoms from baseline to follow-up relative to the control group using mixed-effect models.

DISCUSSION

This is the first trial testing the effectiveness of smartphone apps delivered to school students to prevent depression at scale. Results from this trial will provide much-needed insight into the feasibility of this approach. They stand to inform policy and commission decisions concerning if and how such programmes should be deployed in school-based settings in Australia and beyond.

Development of the Australian neighborhood social fragmentation index and its association with spatial variation in depression across communities

PURPOSE

We know little about how community structures influence the risk of common mental illnesses. This study presents a new way to establish links between depression and social fragmentation, thereby identifying pathways to better target mental health services and prevention programs to the right people in the right place.

METHOD

A principal components analysis (PCA) was conducted to develop the proposed Australian neighborhood social fragmentation index (ANSFI). General practice clinical data were used to identify cases of diagnosed depression. The association between ANSFI and depression was explored using multilevel logistic regression. Spatial hot spots (clusters) of depression prevalence and social fragmentation at the statistical area level 1 (SA1) were examined.

RESULTS

Two components of social fragmentation emerged, reflecting fragmentation related to family structure and mobility. Individuals treated for depression in primary care were more likely to live in neighborhoods with lower socioeconomic status and with higher social fragmentation related to family structure. A 1-SD increase in social fragmentation was associated with a 16% higher depression prevalence (95% CI 11%, 20%). However, the association attenuated with adjustment for neighborhood socio-economic status. Considerable spatial variation in social fragmentation and depression patterns across communities was observed.

CONCLUSIONS

Developing a social fragmentation index for the first time in Australia at a small area level generates a new line of knowledge on the impact of community structures on health risks. Findings may extend our understanding of the mechanisms that drive geographical variation in the incidence of common mental disorders and mental health care.

Stakeholder perspectives on evidence for digital mental health interventions: Implications for accreditation systems

Background

Digital mental health interventions can be effective for treating mental health problems, but uptake by consumers and clinicians is not optimal. The lack of an accreditation pathway for digital mental health interventions is a barrier to their uptake among clinicians and consumers. However, there are a number of factors that may contribute to whether a digital intervention is suitable for recommendation to the public. The aim of this study was to identify the types of evidence that would support the accreditation of digital interventions.

Method

An expert workshop was convened, including researcher, clinician, consumer (people with lived experience of a mental health condition) and policymaker representatives.

Results

Existing methods for assessing the evidence for digital mental health interventions were discussed by the stakeholders present at the workshop. Empirical evidence from randomised controlled trials was identified as a key component for evaluating digital interventions. However, information on the safety of users, data security, user ratings, and fidelity to clinical guidelines, along with data from routine care including adherence, engagement and clinical outcomes, were also identified as important considerations when evaluating an intervention. There are considerable challenges in weighing the evidence for a digital mental health intervention.

Conclusions

Empirical evidence should be the cornerstone of any accreditation system to identify appropriate digital mental health interventions. However, robust accreditation systems should also account for program and user safety, user engagement and experience, and fidelity to clinical treatment guidelines.

Are claims of non-inferiority of Internet and computer-based cognitive-behavioural therapy compared with in-person cognitive-behavioural therapy for adults with anxiety disorders supported by the evidence from head-to-head randomised controlled trials? A systematic review

OBJECTIVE

This review examines the evidence from head-to-head randomised controlled trials addressing whether the efficacy of cognitive-behavioural therapy for anxiety disorders, obsessive-compulsive disorder and post-traumatic stress disorders in adults delivered by computer or online (computer- and Internet-delivered cognitive-behavioural therapy) is not inferior to in-person cognitive-behavioural therapy for reducing levels of symptoms and producing clinically significant gains at post-treatment and at follow-up. A supplementary aim is to examine the evidence for severity as a moderator of the relative efficacy of computer- and Internet-delivered cognitive-behavioural therapy and in-person cognitive-behavioural therapy.

METHOD

PubMed, PsycINFO, Embase and Cochrane database of randomised trials were searched for randomised controlled trials of cognitive-behavioural therapy for these disorders with at least an in-person cognitive-behavioural therapy and Internet or computer cognitive-behavioural therapy arm.

RESULTS

A total of 14 randomised controlled trials (9 Internet, 5 computer) of cognitive-behavioural therapy for social anxiety disorder, panic disorder and specific phobia and 3 reports of effect moderators were included. One study showed a low risk of bias when assessed against risk of bias criteria for non-inferiority trials. The remaining studies were assessed as high or unclear risk of bias. One study found that Internet-delivered cognitive-behavioural therapy was superior and non-inferior at post-treatment and follow-up to group in-person cognitive-behavioural therapy for social anxiety disorder. One study of Internet-delivered cognitive-behavioural therapy for panic disorder showed non-inferiority to individual in-person cognitive-behavioural therapy for responder status at post-treatment and one of Internet cognitive-behavioural therapy for panic disorder for symptom severity at follow-up. Other comparisons (22 Internet, 13 computer) and for estimates pooled for Internet cognitive-behavioural therapy for social anxiety disorder, Internet cognitive-behavioural therapy for panic disorder and computer-delivered cognitive-behavioural therapy studies did not support non-inferiority. Evidence of effect moderation by severity and co-morbidity was mixed.

CONCLUSION

There is limited evidence from randomised controlled trials which supports claims that computer- or Internet-delivered cognitive-behavioural therapy for anxiety disorders is not inferior to in-person delivery. Randomised controlled trials properly designed to test non-inferiority are needed before conclusions about the relative benefits of in-person and Internet- and computer-delivered cognitive-behavioural therapy can be made.

Associations of fatigue and sleep disturbance with nine common mental disorders

OBJECTIVE

To investigate the contribution of nine mental/substance use disorders to fatigue and sleep disturbance.

METHODS

3620 Australians aged 18 years or older recruited from the general community via Facebook during January-February 2016 completed an online survey assessing demographic characteristics, diagnosed medical conditions and nine mental disorders. Outcome measures were Patient Reported Outcomes Measurement Information System (PROMIS®) fatigue and PROMIS sleep disturbance.

RESULTS

Overall, 56% of the sample met criteria for at least one mental disorder. Linear regression models of sleep disturbance revealed all mental disorders except obsessive compulsive disorder (β = 0.038) had independent associations with sleep disturbance, with generalised anxiety disorder (GAD) (β = 0.173), major depressive disorder (MDD) (β = 0.117) and post-traumatic stress disorder (PTSD) (β = 0.111) making the greatest contribution. Inclusion of fatigue in the model attenuated the effects of panic disorder, MDD and attention-deficit hyperactive disorder (ADHD) to non-significance. For the outcome of fatigue, GAD (β = 0.223), MDD (β = 0.176) and PTSD (β = 0.147) made the greatest contributions, although all disorders had significant independent relationships. After adjusting for sleep disturbance, all mental disorders continued to make a significant contribution except for alcohol use disorder and substance use disorder.

CONCLUSION

Sleep disturbance and fatigue have independent associations with many mental disorders after correcting for comorbidity and known confounds. The disorders providing the greatest contribution to sleep disturbance and fatigue were GAD and MDD. Sleep disturbance and fatigue may be appropriate transdiagnostic targets for improving symptoms and global functioning for people with mental disorders.

Suicidal ideation disclosure: Patterns, correlates and outcome

This study aimed to identify how frequently suicidal individuals disclosed their ideation, assess which sources were perceived to be most helpful and identify correlates of disclosure and source helpfulness. A cross-sectional survey was conducted with 1,616 Australian adults reporting suicidal ideation in the past 12-months. Participants were recruited from social media and reported on their disclosure of suicidal thoughts to formal and informal sources. 39% of participants did not disclose to anyone, while 47% disclosed to an informal source and 42% to a health professional. The responses of psychologists and counsellors were perceived to be the most helpful, while parents and hospital-based health professionals were perceived to be the least helpful. Severity of suicidal thoughts, younger age, and a suicide attempt in the past 12-months were associated with greater likelihood of disclosure, while participants who were younger, linguistically diverse, had greater suicidal ideation or personal stigma were less likely to perceive the response of a GP to be helpful. This study demonstrates that non-disclosure of suicidal thoughts is frequent and that the response received to a disclosure may not always be perceived to be helpful. Further research is needed to identify how best to support individuals who disclose suicide.

Suicide Stigma and Suicide Literacy in a Clinical Sample

OBJECTIVE

The aims of this study were to (1) investigate levels and correlates of suicide stigma and suicide literacy in a sample of individuals attending a tertiary depression clinic in Australia (N = 287), with comparison to a community-based Australian sample (N = 1,410), and (2) validate measures of suicide stigma and literacy in a clinical sample.

METHOD

Australian adults (N = 287) aged 18-78 years referred by their general practitioners for assessment at a psychiatric clinic for patients with difficult-to-treat mood disorders were recruited to complete a survey, including measures of suicide literacy, suicide stigma, mental health symptoms, and demographics.

RESULTS

Compared to the Australian community sample, participants in the clinical sample reported lower suicide literacy, lower suicide stigma, greater glorification of suicide, and greater attribution of suicide to isolation. Suicide ideation was associated with greater glorification of suicide. Females had higher suicide literacy and lower suicide stigma than males. The psychometric properties of the suicide stigma measure appeared to be robust and consistent with previous evaluations.

CONCLUSION

Given the low levels of suicide literacy in this clinical sample, suicide prevention initiatives designed for community settings may also be important in clinical settings.

Service Use History of Individuals Enrolling in a Web-Based Suicidal Ideation Treatment Trial: Analysis of Baseline Data

BACKGROUND

A significant recent innovation is the development of internet-based psychological treatments for suicidal thinking. However, we know very little about individuals experiencing suicidal ideation who seek help through Web-based services and, in particular, their previous health service use patterns.

OBJECTIVE

We aimed to examine service use history and its correlates among adults experiencing suicidal ideation who enrolled in a Web-based suicidal ideation treatment trial.

METHODS

We used baseline data of 418 individuals seeking Web-based treatment for their suicidal ideation recruited into a randomized controlled trial of a 6-week Web-based self-help program. Participants at preintervention reported demographic information, clinical characteristics, and health service use over the previous 6 months.

RESULTS

Participants had a high rate of service use in the 6 months before enrolling in the treatment trial (404/418, 96.7% of participants had contact with services). The two most common contact points were general practitioners (385/418, 92.1% of participants) and mental health professionals (295/418, 70.6% of participants). Notably, those with a previous single suicide attempt had lower odds of contact with any service than those with no attempt (odds ratio [OR] 0.21, 95% CI 0.05-0.86; P=.03). Those living in rural or remote areas had lower odds of contacting general practitioners (OR 0.35, 95% CI 0.13-0.91; P=.03) or mental health professionals (OR 0.44, 95% CI 0.23-0.83; P=.01) than those living in metropolitan areas.

CONCLUSIONS

Individuals enrolling in an electronic health intervention trial have often received treatment from general practitioners or mental health professionals. These services can therefore play an important role in preventing the escalation of suicidal thinking. Enrollment in our Web-based treatment trial suggested, though, that face-to-face health services may not be enough. Our study also highlighted the need to improve the provision of coordinated and assertive care after a suicide attempt, as well as health service availability and utilization for those living in rural and remote areas.

Consistency of trajectories of suicidal ideation and depression symptoms: Evidence from a randomized controlled trial

BACKGROUND

Depression is a risk factor for suicidal ideation. However, suicidal ideation can occur in the absence of depression and treating depression may not reduce suicidal thinking. This study tested whether trajectories of suicidal thinking are concordant with trajectories of depressive symptoms and sought to identify factors associated with these trajectories.

METHODS

Participants were community-based Australian adults (N = 418, 77% female) enrolled in a randomized controlled trial evaluating the effectiveness of an online cognitive-behavioral intervention for suicidal ideation. Separate linear growth mixture models were estimated across 12 months of follow-up to identify longitudinal trajectories of suicidal ideation and depression symptoms. Predictors of latent class membership were tested using logistic regression models.

RESULTS

Two-class models were found to have optimal fit for both suicidal thinking and depressive symptoms. Trajectory classes of suicidal ideation were: (1) moderate severity decreasing over time; and (2) high severity remaining stable over time. Depression trajectories were: (1) moderate severity with a small decrease over time; and (2) high severity that decreased moderately over time. Lower perceived burdensomeness was associated with having a greater decrease in both suicidal thinking and depression. More severe mental health symptoms were associated with less decrease in depression symptoms but not with suicidal ideation trajectory.

CONCLUSION

Class membership across the two outcomes and predictors of class membership were found to be largely independent. The lack of coupling in trajectories and predictors suggests that changes in suicidal thinking may occur independently of changes in depression.
