Randomised controlled trial of an online mental health and suicide gatekeeper resource for parents and caregivers: study protocol.

INTRODUCTION: Rates of help-seeking for mental disorders and suicide are low among children and adolescents. Parents are viewed as gatekeepers for their care, yet they may lack the knowledge and skills to identify needs or facilitate service access. The primary aim is to test the effect of a new gatekeeper resource for parents and caregivers on their self-efficacy to recognise, respond and access support for mental health problems and suicide risk in their child. METHODS AND ANALYSIS: A two-arm randomised controlled trial will compare an online mental health and suicide gatekeeper resource for parents and caregivers to a waitlist control. Australian parents of children aged 5-17 years recruited through social media and community advertising will participate in an online trial. Participants randomised to the intervention condition will be emailed the resource to work through at their own pace. The resource consists of three sections providing parents and caregivers with confidence, knowledge and skills to recognise and respond to mental health problems and suicide risk in their child, as well as support them in accessing professional help. The primary outcome measure is self-efficacy to recognise, respond and provide support for mental health problems and suicide risk, while secondary outcomes include perceived knowledge, stigma, literacy, help-seeking attitudes, intentions and barriers. Data will be collected at preintervention, postintervention (4 weeks after accessing the resource) and 12-week follow-up. Primary analyses will compare changes in self-efficacy in the intervention condition relative to the waitlist control using mixed-model repeated measures analyses. ETHICS AND DISSEMINATION: The ethical aspects of the study were approved by the Australian National University Human Research Ethics Committee (Protocol 2023/195). If effective, the resource will fill an important gap in resources for parents, with the potential for dissemination through school groups, community organisations and clinical settings.

Understanding suicidal transitions in Australian adults: protocol for the LifeTrack prospective longitudinal cohort study.

BACKGROUND: The factors that influence transition from suicidal ideation to a suicide attempt or remission of suicidal thoughts are poorly understood. Despite an abundance of research on risk factors for suicidal ideation, no large-scale longitudinal population-based studies have specifically recruited people with suicidal ideation to examine the mechanisms underlying critical transitions to either suicide attempt or recovery from suicidal ideation. Without longitudinal data on the psychological, behavioural, and social determinants of suicide attempt and the remission of suicidal ideation, we are unlikely to see major gains in the prevention of suicide. AIM: The LifeTrack Project is a population-based longitudinal cohort study that aims to identify key modifiable risk and protective factors that predict the transition from suicidal ideation to suicide attempt or remission of suicidal ideation. We will assess theory-informed risk and protective factors using validated and efficient measures to identify distinct trajectories reflecting changes in severity of suicidal ideation and transition to suicide attempt over three years. METHODS: A three-year prospective population-based longitudinal cohort study will be conducted with adults from the general Australian population who initially report suicidal ideation (n = 842). Eligibility criteria include recent suicidal ideation (past 30 days), aged 18 years or older, living in Australia and fluent in English. Those with a suicide attempt in past 30 days or who are unable to participate in a long-term study will be excluded. Participants will be asked to complete online assessments related to psychopathology, cognition, psychological factors, social factors, mental health treatment use, and environmental exposures at baseline and every six months during this three-year period. One week of daily measurement bursts (ecological momentary assessments) at yearly intervals will also capture short-term fluctuations in suicidal ideation, perceived burdensomeness, thwarted belongingness, capability for suicide, and distress. CONCLUSION: This study is intended to identify potential targets for novel and tailored therapies for people experiencing suicidal ideation and improve targeting of suicide prevention programs. Even modest improvements in current treatments may lead to important reductions in suicide attempts and deaths.

Systematic review of quantitative studies assessing the relationship between environment and mental health in rural areas.

OBJECTIVE: Physical and natural environments might strongly influence mental health and well-being. Many studies have examined this relationship in urban environments, with fewer focused on rural settings. The aim of this systematic review was to synthesise quantitative evidence for the relationship between environmental factors (drought, climate and extreme weather events, land use/environmental degradation, green space/vegetation, engagement in natural resource management activities) and mental health or well-being in rural areas. DESIGN: Following a systematic search of three databases (PsycINFO, MEDLINE and Web of Science), 4368 articles were identified, of which 28 met eligibility criteria for inclusion in the review. RESULTS: Poorer mental health and well-being was typically found to have an association with extreme climate or weather events and environmental degradation. The observed relationships were largely assessed at area-wide or community levels. CONCLUSIONS: Studies examining the relationship between the environmental condition of land and mental health at an individual level, particularly within farms, are lacking. Addressing this gap in research requires interdisciplinary expertise and diverse methodology. Few studies examined the effects of natural resource management practices/principles or biodiversity on mental health. While there is evidence that extreme climate or weather events have a negative impact on mental health in rural areas, there remain considerable gaps in our knowledge of how rural environments influence mental health and well-being.

Rates and Predictors of Deterioration in a Trial of Internet-Delivered Cognitive Behavioral Therapy for Reducing Suicidal Thoughts.

OBJECTIVE: It is necessary for suicide prevention interventions to demonstrate safety. One important aspect of safety is evidence that deterioration rates are low. No studies have examined deterioration of suicidal ideation in the context of an internet-based cognitive behavioral therapy (CBT) intervention to reduce suicidal ideation. A secondary analysis of the outcomes of an online trial was conducted to determine rates of deterioration in a CBT intervention called Living with Deadly Thoughts, relative to an attention control condition, and to identify factors associated with deterioration. METHOD: The randomized controlled trial included 418 adults with suicidal ideation at baseline (77% females, mean age 40.6 years). Deterioration was defined in two ways: a reliable increase in Suicidal Ideation Attributes Scale (SIDAS score) of ≥6.0 units; or triggering the safety protocol during the trial as determined by high levels of suicidality. Analyses were repeated with multiply imputed data. Predictors of deterioration were identified using logistic regression analysis. RESULTS: 30 (14%) participants in the control group and 15 (7%) in the intervention group met criteria for reliable deterioration (Fisher's exact p = 0.027). In a fully adjusted logistic regression model, greater initial severity of suicidal thinking was associated with lower odds of deterioration, while intervention condition, demographics, psychological factors and mental health factors had no significant association with deterioration. CONCLUSIONS: Participation in an online suicide prevention intervention was associated with lower prevalence of reliable deterioration than participation in an attention-control intervention, providing further evidence that internet-based CBT interventions do not cause harm.HighlightsFirst study to assess deterioration in an internet suicide prevention interventionRates of reliable deterioration were higher in control (14%) than intervention (7%)No psychological or demographic factors were robustly associated with deteriorationFindings provide further evidence that internet based CBT programs are not harmful.

The Sources of Strength Australia project: A cluster randomised controlled trial of a peer-connectedness school-based program to promote help-seeking in adolescents.

BACKGROUND: Suicide is a significant public health problem and there is a clear need for interventions to improve help seeking for suicide and psychological distress in young people. This trial aimed to assess the effectiveness of the school-based Sources of Strength program in increasing help-seeking intentions and behaviours in adolescents. METHODS: A cluster, randomised controlled trial was conducted in 13 Australian secondary schools (N = 1633), with each school randomly allocated to the intervention (n = 7) or wait-list control condition (n = 6). Participants in the intervention condition received the Sources of Strength program over two years and all participants completed self-report measures of help-seeking intentions and behaviour at four time-points. Staff and students in the intervention condition also provided qualitative feedback on the perceived impact of the program. RESULTS: Mixed model repeated measures analyses demonstrated no significant effect of the Sources of Strength program on help-seeking intentions or behaviour at post-intervention or 6- or 18-month follow-up. Staff and students reported, through qualitative feedback, that the program increased awareness of and openness to help seeking and promoted a common language and school community. LIMITATIONS: The current study only included self-report measures that may have been influenced by situational factors or biases. CONCLUSIONS: Although the Sources of Strength program may have increased awareness of help seeking, there was no evidence that it is effective in increasing help-seeking intentions or behaviours in this cohort. The program may be more suitable for schools in disadvantaged areas where there may be limited existing connections to trusted adults.

Application of the Interpersonal Psychological Theory of Suicide in a non-clinical community-based adolescent population.

BACKGROUND: The Interpersonal Psychological Theory of Suicide (IPTS) provides a theoretical model of suicide behavior that explains the emergence of suicidal ideation and suicide attempt. Limited research has tested the IPTS with adolescents. The aim of the current study is to test the full IPTS model in a non-clinical community-based sample of adolescents. METHODS: Data for the current study are drawn from the pre-intervention survey of the school-based Sources of Strength Australia Project, which included 1,382 adolescents aged 12-17 years. Participants completed measures of perceived burdensomeness, thwarted belongingness, capability for suicide (fearlessness about death), and suicidal ideation and behavior. The IPTS models were tested using hierarchical linear and logistic regression analyses. RESULTS: Perceived burdensomeness and thwarted belongingness, and their interaction, were significantly (p< 0.001) associated with higher levels of suicidal ideation in the past month. The three-way interaction of perceived burdensomeness, thwarted belongingness and capability for suicide was not significantly associated with having had at least one suicide attempt in the past 12 months (p= 0.052). LIMITATIONS: The data are cross-sectional and due to the low prevalence of suicide attempts in the sample, the study may be underpowered to fully test effects for suicidal behavior. CONCLUSIONS: The results of the current study support the predictions of the IPTS in relation to suicidal ideation in adolescents. Given the clear associations between perceived burdensomeness and thwarted belongingness with suicide risk in adolescents there may be value in targeting these factors in the assessment and prevention of suicide in this population.

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 (ß = 0.038) had independent associations with sleep disturbance, with generalised anxiety disorder (GAD) (ß = 0.173), major depressive disorder (MDD) (ß = 0.117) and post-traumatic stress disorder (PTSD) (ß = 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 (ß = 0.223), MDD (ß = 0.176) and PTSD (ß = 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.

The Sources of Strength Australia Project: study protocol for a cluster randomised controlled trial.

BACKGROUND: The school system has been identified as an ideal setting for the implementation of prevention and early intervention programs for suicide. However, in Australia, suicide-prevention programs that are routinely delivered in the schools are lacking. Internationally, evidence exists for the effectiveness of peer-led interventions that take a social connectedness approach to improve help-seeking for suicide. The aim of the current trial is to test the effectiveness of the Sources of Strength program to promote help-seeking for suicide in adolescents in Australian high schools. METHODS/DESIGN: This study is a two-arm, cluster-randomised, controlled trial that will compare the evidence-based Sources of Strength program to a wait-list control condition. Sixteen Australian high schools will be recruited to the trial, with all adolescents in years 7 to 10 (12-16 years of age) invited to participate. Peer leaders from intervention-condition schools will receive training in the Sources of Strength program and will integrate positive messages, across 3 months, with the support of adult advisors. Activities may take the form of class presentations, posters, videos, and messages on social media sites and will aim to change help-seeking norms, strengthen youth-adult connections, and promote positive coping. The primary outcome measure for the study is help-seeking intentions, whereas secondary outcomes include help-seeking behaviour, help-seeking attitudes and norms, referral of distressed peers, availability of adult help, positive coping, and suicidal behaviour. Data will be collected pre-intervention, post-intervention (after the initial 3 months of messaging), and at the end of the first (6-month follow-up) and the second year after implementation (18-month follow-up). Primary analyses will compare changes in help-seeking intentions for the intervention condition relative to the wait-list control condition using mixed-effect repeated-measures analyses to account for clustering within schools. DISCUSSION: If proven effective, this universal social connectedness program for suicide could be more widely delivered in Australian high schools, providing a valuable new resource. The Sources of Strength program has the potential to significantly contribute to the mental health of young people in Australia by improving help-seeking for suicide. The findings from this research will also contribute to the evidence-base for peer-leadership programs internationally.

The impact of intimate partner relationships on suicidal thoughts and behaviours: A systematic review.

BACKGROUND: A systematic review was conducted to identify the impact of intimate partner relationships on suicidality. The aim of the review was to identify factors within intimate partner relationships that influence suicidal ideation, attempts and completion. METHOD: Fifty-one articles were identified through Scopus, PubMed and PsycINFO databases. Due to the high heterogeneity of the included studies, a narrative data synthesis was conducted. RESULTS: The research drew attention to specific contingents of the population, for example examining suicide risk in individuals under the age of 35 or lesbian, gay, bisexual and transgender (LGBT) individuals who are experiencing relationship discord, and in males who have recently separated. LIMITATIONS: Interpretation of these findings is constrained by methodological limitations prevalent in much of the literature. Limitations of the existing literature and corresponding directions for future research are discussed. CONCLUSIONS: Relationship separation and poor quality relationships are likely to be important risk factors for suicidal thoughts and behaviours and are frequent triggers for a suicide attempt. This review highlights intimate partner relationships as a significant component in a suicide risk assessment, regardless of the clinical setting. Consequently, clinicians should be aware that individuals reporting relationship problems are likely to be at increased risk of suicidal thoughts and behaviours.
