The aim of this project is to assess if adding one of two structured suicide specific psychological interventions to a standardised clinical care approach improves outcomes for consumers presenting to a Mental Health Service with a suicide attempt. The standardised care approach involves a Suicide Prevention Pathway (SPP) modelled on the Zero Suicide Framework. The Attempted Suicide Short Intervention Program (ASSIP) is a manualised therapy composed of three therapy sessions following a suicide attempt, with subsequent follow up over two years with personalised mailed letters. Cognitive Behavioural Therapy (CBT)-Based Psychoeducational Intervention is a manualised approach involving brief CBT for suicide in five 60 minute sessions. The intervention incorporates skills development and emphasises internal self-management. We will compare outcomes for: 1. The Attempted Suicide Short Intervention Program (ASSIP) + SPP, versus SPP alone 2. Five Sessions of Cognitive Behavioural Therapy (CBT) + SPP, versus SPP alone 3. CBT + SPP versus ASSIP + SPP. Hypotheses: 1. The use of suicide specific psychological interventions (ASSIP; CBT) combined with a comprehensive clinical suicide prevention pathway (SPP) will have better outcomes than the clinical suicide prevention pathway alone. 2. Outcomes for the ASSIP + SPP and CBT + SPP will significantly differ. 3. Cost-benefit analyses will significantly differ between ASSIP and CBT.
Key literature: Treatment approaches for suicide: The efficacy of various suicide prevention interventions has been the subject of research for some time, and includes a number of recent systematic reviews (e.g. Zalsman et al., 2016), and Gould, Greenberg, Velting, and Shaffer (2003) reviewed suicide prevention strategies specifically used with young people. Current national suicide prevention programs have highlighted the knowledge that suicide is a behaviour that stems from a complex and multifaceted set of circumstances and individual characteristics. These factors can be present across the human lifespan and occur across multiple cultural and community settings. The complex heterogeneous nature of the factors influencing suicide rates requires a collaborative and coordinated systems approach, incorporating strategies simultaneously implemented across multiple levels, including service systems, individualised interventions and community prevention. Despite this recognition, there remains a significant gap in the evidence base regarding the most effective interventions for use with suicide at the hospital service level. In 2015, the Gold Coast Mental Heath and Specialist Services (GCMHSS) undertook a review of frameworks for suicide prevention to guide planning and choice of interventions, as well as enhancing the capability of the service and staff to provide interventions aimed at addressing the needs of people presenting as a result of a suicide attempt. Interventions were sought with available evidence of efficacy, based on outcomes obtained in clinical, controlled trials (particularly those suitable for the top six diagnostic related groups for mental health presenting to the Gold Coast Hospital Health Service (GCHHS), with the aim to provide recommendations for service wide implementation. The top six high priority mental health diagnostic groups included: schizophrenia \& related disorders, mood/affective disorders, alcohol \& substance related disorders, personality disorders, suicidal behaviours, and stress/adjustment/situational crisis. Two of the interventions that demonstrated the strongest quality of evidence included the Attempted Suicide Short Intervention Program (ASSIP) and Cognitive Behavioural Therapy (CBT) based psychological intervention. This is a randomised controlled trial, with blinding of those assessing the outcomes. Primary outcome measures: Representation to hospital with suicide attempt and/or suicidal ideations within 7, 14, 30 and 90 days post intervention. Death by suicide rates will also be examined. Death clearly assessed as not involving self-harm will be represented as not completing the study. Secondary outcome measures: Self-reported level of suicidality, depression, anxiety, stress, resilience, problem solving skills and self- and therapist-reported level of therapeutic engagement. Cost-benefit measures are assessed for both interventions. All consumers who attempt suicide during the trial period, and are 16 years of age and older, will be offered the opportunity to join the trial. Specific demographic questions will identify the numbers of people who fall within specific target groups to enable a determination regarding any differences in the results being statistically significant. A consumer/carer representative will participate on the research team, to inform the research and ensure sensitivity to the experiences of consumers with lived experience.

The first session is based on a narrative interview with the consumer relating the personal story of how the point of attempting suicide was reached, videorecorded with consent. The second session involves the therapist and consumer watching the session together to reactivate the consumer's mental state during the crisis in a safe environment. Automatic thoughts, emotions, psychological pain and stress, and contingent behaviour are discussed. A psycho-educative handout is given to consumers. The third session involves discussing the handout. A credit card size leaflet is provided, with long term goals, individual warning signs and safety strategies listed, in addition to a card with crisis phone numbers. The sessions are followed by letters sent over 24 months (Michel, Valach \& Gysin-Maillart, 2017).
The intervention incorporates skills development and emphasises internal self-management. Therapy focuses on the identification of internal, external and/or thematic triggers for suicidal thinking and behaviours, as well as factors that maintain the desire to suicide, using thought records and/or chain analyses. Therapy aims to challenge distortions and misconceptions, including core beliefs that interfere with the motivation to initiate the process of problem solving and distress tolerance, by working on acceptance of emotional and/or physical pain. The final phase of treatment focuses on relapse prevention. CBT can challenge maladaptive beliefs, improve problem solving skills and social competence.
The standardised care approach involves a Suicide Prevention Pathway (SPP) modelled on the Zero Suicide Framework, utilising comprehensive chronological assessment of suicide events (CASE) (Shea, 2009) to elicit suicidal intent, the prevention orientated risk formulation (Pisani, Murrie, \& Silverman, 2016), brief interventions conducted with the consumer during their initial assessment prior to the treatment setting (Stanley et al., 2016), Safety Planning Intervention, Counselling on Access to Lethal Means (CALM), brief patient/carer information, rapid, structured follow up, safe transitions of care and caring contacts (Fleischmann et al., 2008). The SPP is supported by a blended learning course with online and face-to-face training for staff.

Columbia Suicide Severity Rating Scale (C-SSRS)
The Columbia Suicide Severity Rating Scale (C-SSRS) is a suicide ideation and behaviour rating scale that supports suicide assessment through a series of simple, plain-language questions that anyone can ask. The maximum suicidal ideation category (1-5 on the C-SSRS) present at the assessment. A score of 0 indicates that no suicide ideation is present.
Time frame: Baseline (pre-intervention); end of intervention (up to 5 weeks); and 6-, 12- and 24 months from baseline
Depression, Anxiety and Stress Scale (DASS)
The Depression, Anxiety and Stress Scale (DASS) is a set of three self-report scales (21 item version) designed to measure the negative emotional states of depression, anxiety and stress. For this short (21-item) version of the DASS, Stress, Anxiety, and Depression scores a multiplied by 2 to get a score of 42 for each subscale (score 0-42). Higher scores of each subscale indicate higher emotional states of depression, anxiety, or stress.
Time frame: Baseline (pre-intervention); end of intervention (up to 5 weeks); and 6-, 12- and 24 months from baseline
The Coping Inventory for Stressful Situations (CISS)
The Coping Inventory for Stressful Situations (CISS) is a 48 item self-report questionnaire for clinical and non-clinical settings. The CISS is a four-factor model of human coping with adversity. The construct differentiates three types of coping: emotion-orientated (7 items), task orientated (7 items), and avoidance (distracted or social; 7 items). Respondents rate each item on a five point scale: (1) Not at all to (5) Very much. Scores range from 7-35 for each subscale (emotion-orientated coping, task-orientated coping, and avoidance coping). Higher scores indicate greater preference for task-orientated, emotion-orientated, or avoidance coping style.
Time frame: Baseline (pre-intervention); end of intervention (up to 5 weeks); and 6-, 12- and 24 months from baseline
Resilience Scale for Adults (RSA)
