The Effect of a Brief Psychological Intervention on Reducing Self-harm Repetition: Feasibility Study
Study Details
Study Description
Brief Summary
Recent research has focused on examining brief interventions for reducing self-harm, such as the volitional help sheet (VHS). The VHS is a theory-based psychological intervention. Two previous studies applying this tool for reducing self-harm repetition showed inconsistent results; one showed reduced subsequent self-reported suicidal ideation and behavior in patients presenting to hospital for self-harm, whilst the other showed no effect on the number of patients who re-presented to hospital with self-harm. The aim of this study is to investigate the feasibility of the VHS intervention amongst self-harm patients in Taiwan and explore its effect on self-harm repetition based on self-reported self-harm, hospital re-presentations with self-harm, and self-harm episodes from a nationwide self-harm registry. It is a two-phase study: first a qualitative study and second an exploratory randomized control trial. The first study is to interview people who self-harm about their perceptions about the VHS on the online platform, to inform the modification of VHS and the best way to intervene. The second is to examine the feasibility and effect of this intervention at the emergency department setting.

Detailed Description
Suicide is an important public health issue and leads to substantial social and economic burden. Self-harm is a significant risk factor of subsequent suicide attempt and suicide. However, previously studied interventions for reducing self-harm repetition such as long-term psychological therapies would not be feasible at acute settings such as emergency departments. It is also challenging to maintain patients who self-harm in long-term treatments. The volitional help sheet (VHS) is a brief, theory-based psychological intervention. Two recent studies applying this tool for reducing self-harm repetition showed inconsistent results; one showed reduced subsequent self-reported suicidal ideation and behavior in patients presenting to hospital for self-harm, whilst the other showed no effect on the number of patients who re-presented to hospital with self-harm. To investigate the feasibility of the VHS intervention for self-harm patients and explore its effect on self-harm repetition in Taiwan, the investigators will conduct a two-phase study: first a qualitative study and second an exploratory randomized control trial.
In phase I, the qualitative study, eight patients with recent self-harm will be recruited from the psychiatric ward and interviewed about their perceptions about the VHS and views about the best way to intervene.
In phase II, the exploratory randomized control trial, the investigators will recruit 60 patients presenting to the emergency department following an episode of self-harm. Patients will be randomly assigned (1:1) to the intervention group, which will be given the VHS intervention on an online platform, or the control group to examine the feasibility and effect of this intervention. The primary outcomes will be self-harm repetition based on: i) self-reported self-harm in a telephone based follow-up survey, ii) hospital re-presentations with self-harm based on hospital records, and iii) self-harm episodes from a nationwide self-harm registry, the National Suicide Surveillance System (NSSS). The NSSS includes a web-based reporting system and all emergency departments across the country are asked to report information about all people present to hospitals following an episode of self-harm. In addition, we will report the sub-group analyses for past self-harm hospitalisation according to the suggestion from the study testing VHS on reducing self-harm in United Kingdom.
Study Design
Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Experimental: VHS group Patients will be asked to make links between critical situations and appropriate solutions in the volitional help sheet (VHS). |
Behavioral: the volitional help sheet
A sheet includes two columns: one shows critical situations that easily trigger self-harm; other one shows appropriate solutions for patients to prevent self-harm.
|
| No Intervention: Control group Patients will be asked to read the VHS. This is an active control group. That means all patients in this study will be exposed to situations and solutions in the VHS. |
