Inclusion criteria

Inclusion criteria: 1. Aged =18 years 2. Accessing full or part time education through a HEI 3. Suicidal ideation and/or behaviours in the past three months, ascertained using the questions ‘have you had any thoughts about ending your life in the past three months?’ and ‘have you attempted to end your life in the past three months?’. Endorsement of either item will confirm eligibility for the trial and progression to full assessment. This approach is consistent with previous trials and is sensitive to detecting suicidal experiences amongst adults

Exclusion criteria

Exclusion criteria: 1. Active/historical full threshold first episode psychosis or bipolar disorder as identified by the patient or referring service and the MINI diagnostic interview. 2. Known moderate to severe learning disability (IQ:<70). 3. Organic cerebral disease/injury affecting receptive and expressive language comprehension. 4. Non-English speaking to the degree that the participant is unable to answer questions and give written informed consent. 5. Imminent and immediate risk to self or others, operationalised as the presence of active intent or planning to harm oneself or others in the near future (e.g. next month). Where individuals are excluded on this basis, with the person’s consent, the researcher will aim to recontact them and the referrer in approximately one-month’s time (or a time period agreed in collaboration with the individual) to determine if risk has subsided to a point where they are now eligible.

Design outcomes

Primary

MeasureTime frame
Feasibility outcomes measured using participant records: 1. Recruitment rates: Ability to randomise 66 participants in an 11-month recruitment window 2. Adherence to treatment: Percentage of participants receiving the minimum dose of therapy (=2 sessions) within eight-week treatment window 3. Retention to follow-up: Percentage of participants completing the 24-week assessment as potential primary outcome timepoint 4. Suitability of proposed primary outcome: Informed by qualitative workstream plus percentage of participants completing the Beck Scale for Suicidal ideation at all timepoints 5. Safety of trial participation: Monitoring and review of research related serious adverse events (SAEs).

Secondary

MeasureTime frame
Measured at baseline, 8, 16 and 24 weeks: 1. Beck Scale for Suicidal Ideation 2. Linehan Suicide-Attempt Self-Injury Interview items 3. Self-injurious Thoughts and Behaviours Interview items 4.
