Description of intervention(s) / exposure
Group 1: Control: treatment as usual

Group 2: Expanded assessment including standardized measures of attentional conditions and difficulties with emotional processing, and the semi-structured diagnostic interview (K-SADS).

Schedule for Affective Disorders and Schizophrenia for School Age Children Present and Lifetime Version (K-SADS-PL) is most widely used diagnostic interviews in research. It is a standardized semi-structured interview to measure current and past symptoms of mood, anxiety, psychotic and disruptive behaviour disorders (including ADHD) in children aged 6-18 years old. Administration time is between 45-75 minutes. The K-SADS diagnostic interview takes between 1-2 hours to administer

Group 3: Expanded Assessment with Nested Intervention - Therapeutic Assessment: a brief, manualised psychological assessment technique developed specifically to make the assessment for children and adolescents who have self-harmed more therapeutic

Therapeutic Assessment (TA; Ougrin et al., 2009) is a brief, manualised psychological assessment technique developed specifically to make the assessment for children and adolescents who have self-harmed more therapeutic (Ougrin et al., 2009). TA is a therapeutic intervention where the clinician and patient co-construct a narrative with regards to their DSH / suicidal crisis behaviours within the context of a theoretical model developed by Ougrin and colleagues (2009) over a single 1-hour to 1.5-hour session. The content of this session is then recorded in a ‘therapeutic letter’ and provided to the patient in paper mail form (with an additional electronic form provided if requested.

The intervention will be delivered by a Clinical Psychologist, and/ or masters-level provisionally registered Clinical Psychologists, supervised by a Clinical Psychologist. Therapeutic assessment takes between 1-1.5 hours to complete with the patient.

Both the K-SADS and the Therapeutic Assessment are delivered as a one-off intervention. The intervention is delivered at the Perth Children’s Hospital in an outpatient clinic available to clinical researchers.

Clinicians delivering the interventions receive training and supervision. Output generated from interventions (K-SADS results and Therapeutic Assessment letter) are reviewed by the PI and/ or CPI to ensure correct administration.

Both the K-SADS and Therapeutic Assessment are readily available and have not been modified for use in this study.

Prevention
Comparator / control treatment
Treatment as usual

All children and adolescents who present to PCH ED with DSH/ Suicidal crisis receive:
• Triage by ED Nurse
• Assessment and treatment where required by ED doctor – usually competed by JMO or RMO. Clinical decisions discussed with ED Consultant Paediatrician on duty.
• Mental Health Assessment by Clinical Nurse Specialist – Mental Health Nurse.
o This involves a psycho-social assessment, including screening for co-morbid mental health conditions such as depression and anxiety.
o Risk assessment (including risk and protective factors) to inform a Risk Management Plan.
o Care Plan (discharge plan)

Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Allocation is not concealed
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Treatment group allocation for the trial will utilize computer-generated minimisation, that incorporates weighted randomisation, via a local implementation of the MimimPy algorithm (Saghaei & Saghaei, 2011). The minimisation algorithm will ensure balance between intervention groups for several selected patient factors (gender and presentation status).
Masking / blinding

Efficacy
Statistical methods / analysis
It is planned to recruit at least 100 in each arm, ensuring at least 90 per group are available for analysis, with this sample size being a pragmatic choice which balances power and feasibility of implementation.

Primary outcome: Based on pilot data we expect that under standard care over 50% of first-time presenters will re-present to ED within 6 months (estimated rate = 0.75 re-presentations/6 mths), and over 75% of recurrent presenters (estimated rate = 1.5 re-presentations/6 mths). Given the combined-sample recruitment of both first-time and recurrent presenters, the power of our planned study was examined via 1000 simulations based on randomly-generated Poisson data defined by these estimated parameters. With recruitment expected to include approximately 90 first-timers and 180 recurrent presenters, and allocation of equal numbers to receive standard care, expanded assessment only or expanded assessment plus intervention, the simulation study has indicated we will have more than 80% power to detect at least a 34% reduction in the re-presentation rates by receipt of the intervention.

For the primary outcome, rates of re-presentation will be analysed by regression modelling appropriate for count data (Poisson, or quasi-Poisson or negative binomial if better suited to the data), with time considered as an exposure variable. Group differences will be examined by contrasts specified in the regression modelling: (1) Separate indicators for Group 2 and Group 3 will compare re-presentation rates with Group 1, as the baseline; (2) Inclusion of one indicator for membership of either Group 2 or 3 and another indicator for Group 3 membership will assess impact of the intervention over and above receipt of the expanded assessment. Presentation type and gender, important prognostic factors, will be included as covariates in the regression model. Analyses will also consider differential assessment group effects across presentation type by inclusion of an interaction term.

Secondary analyses: Logistic regression will be used for analysis of acute and sub-acute engagement with treatment, Poisson regression for counts of reported deliberate self-harm episodes, and ordinal regression for medical seriousness and potential lethality. Where these outcomes measures have been collected on multiple occasions, the analyses will be undertaken within the appropriate mixed-effects regression framework.
