Text Message Intervention to Reduce Repeat Self-harm
Study Details
Study Description
Brief Summary
Between 6% and 30% of people who harm themselves repeat this self-harm within the following 12 months. The investigators know that people who harm themselves are much more likely to commit suicide, but the investigators have no clear evidence about the best way to reduce the likelihood of someone harming themselves again.
Text messaging is now a common form of communication. Previous research has shown us that the investigators can use text messages for different types of health care interventions. Examples of this include reminding patients of medical appointments, delivering test results, to check patient side effects following treatment and to reduce depressive symptoms in patients with depression and alcohol problems. The Samaritans have introduced interactive text messages (where you can have a conversation by text with their service) and have noted an increasing use of this contact with their service.
This research study is taking place to find out if using supportive and interactive text messages can reduce further episodes of self-harm in patients who present to the Emergency Department (ED) with self-harm.
The investigators hypothesize that supportive, informative and interactive text messages delivered to patients discharged from an ED after an episode of self-harm will significantly reduce the frequency and intensity of thoughts of self-harm and self-harming behaviour in patients compared with those receiving only follow-up treatment as usual. A secondary hypothesis is that patients receiving the text messages will report a favourable experience and an overall satisfaction with the system.

Detailed Description
Repetition of self-harm is common, ranging from 6% to 30% in 12 months. Repetition is strongly associated with subsequent suicide and has important implications for healthcare resources. In every country including Ireland, fatal suicide attempts rank among the top ten causes of death for individual of all ages and one of the three leading causes of death in the 15 -35 years age group.
Previous studies of interventions to reduce the repetition of self-harm in unselected patient groups have been unsuccessful in reducing the proportion of repeaters. These interventions have included the use of antidepressants, problem solving, intensive care with outreach, an emergency card, psychosocial crisis intervention, and guaranteed inpatient shelter in cases of emergency. In a study involving the use of low cost postcards after an episode of self-poisoning, although no significant difference in the proportion of individual patients who repeated self-harm were detected, there was a clinically and statistically significant reduction in the number of events per individual by about 50%.
Only a few non-pharmacological interventions have been reported to be effective in reducing repetition in selected subsets of populations with self-harm including; partial hospitalization, dialectical behaviour therapy and psychodynamic interpersonal therapy. These interventions are all resource intensive and therefore may only be applicable to carefully selected patients.
Given the recent global financial crisis with consequent diminution of health care resources, interventions are needed that could be delivered economically to entire populations of patients who self-harm. In light of the growing interest in using text messages as an intervention in healthcare, the investigators will focus in this study on exploring the potential for using text messages to reduce repeat self-harm in patients presenting to the Emergency Department (ED).
There is established research evidence for using text messages to remind patients of scheduled medical appointments, to coordinate medical staff,to deliver medical test results and to monitor patient side effects following treatment.
In a review of the literature on the use of text messaging for clinical and healthy behaviour interventions, Wei et al. (2011) found that among 16 randomized controlled trials, 10 reported significant improvement with interventions and six reported differences suggesting positive trends. In one meta-analysis of four randomised trials of mobile phone-based interventions for smoking cessation, it was reported that text message interventions resulted in a significant increase in short-term self-reported quitting (RR of 2.18, 95% CI 1.80 to 2.65). In the same review, when data from an internet and a mobile phone programme were pooled and meta-analysed, they found significant increases in both short-, and long-term, self-reported quitting (RR of 2.03, 95% Conficence Intervals (CI)= 1.40 to 2.94).
In a study of text message services based on qualitative interviews with 12 young people, the aim of which was to provide young people with information on cannabis and help them to reduce their consumption of the drug, participants reported that they saw the messages as flexible and discrete, and as being personally meant for them. They paid more attention to the messages than they did to mass approaches such as public information broadcasts on TV. Along with other factors, the participants reported feeling motivated to decrease their level of cannabis abuse and to maintain a reduced level. .
In another study, young adults in 3 urban EDs (n= 45; aged 18 to 24 years, 54% women) who were identified as hazardous drinkers by the Alcohol Use Disorders Identification Test-Consumption Score were randomly assigned by the researchers to weekly text message-based feedback with goal setting (Intervention), weekly text message-based drinking assessments without feedback (Assessment), or to a control who received no text messages. At 3 months, they found that participants who were exposed to the text message-based intervention had 3.4 (Standard Deviation (SD)= 5.4) fewer heavy drinking days in the last month and 2.1 (SD 1.5) fewer drinks per drinking day when compared to baseline.
In a recent randomised trial in Ireland of supportive text messages for patients with depression and comorbid alcohol use disorder, there was a trend towards finding a greater cumulative abstinence duration in the group that received twice daily supportive text messages compared to the control group who only received fortnightly tank you text messages: 88.3 (SD=6.2) vs. 79.3 (SD=24.1), t=1.78, df=48, p=0.08. In this trial, after adjusting for baseline scores, patients in the supportive text message group also had significantly lower Beck's Depression Inventory Scores compared to the control groups; 8.5 (SD=8.0) vs. 16.7 (SD=10.3) respectively, F (1, 49) = 9.54, p=0.003, ƞp2=0.17.
In a study by Owens et al. (2010) to engage a group of self-harmers in the development of a text-messaging intervention to reduce repetition of self-harm, three broad categories of message emerged, namely, those that affirmed or validated emotions (e.g. "it's ok to feel angry"), those that prescribed actions, distractions or cognitive strategies (e.g. "call Samaritans," "have a warm bath"," take it a minute at a time") and those that were interrogative or designed to initiate dialogue (e.g. "do you want to talk?"). They also found that the group were unable to reach an agreement on a set of messages that might work in all circumstances to reduce the urge to self-harm or to enable people to feel cared for, concluding instead that text messages may need to be individualised. A major limitation of this study was its small sample size of only 8 people. Furthermore, participants in this study only reported how they envisaged they would respond to text messages rather than how they actually responded to text messages which could vary significantly from what is reported. In the recent randomised trial in Ireland of generic supportive text messages for patients with depression and comorbid alcohol use disorder, 20 of the 24 patients (83%) reported that the intervention had played a useful role in helping to improve their mental health.
Recently, the Samaritans in Ireland introduce a limited interactive text message programme for patients who experience suicidal ideation. This service allows clients to receive support when in crisis via an interactive text messaging programme from a trained volunteer.
After an extensive review of the literature using Google Scholar, MEDLINE, Pub Med, ERIC, Web of Science, Science Direct and PsychINFO, no published randomised trial was found on the use of text messages delivered via mobile phone as an intervention to address suicidal ideation and repeat self-harm in patients presenting with self-harm to the ED. Thus, the investigators seek to determine if text messaging is a useful and effective strategy to help reduce the frequency and intensity of thoughts of self-harm and depressive symptoms after patients are discharged from an ED following a presentation with self-harm.
The investigators hypothesize that supportive, informative and interactive text messages delivered to patients discharged from an ED after an episode of self-harm will significantly reduce the frequency and intensity of thoughts of self-harm and self-harming behaviour in patients compared with those receiving only follow-up treatment as usual. A secondary hypothesis is that patients receiving the text messages will report a favourable experience and an overall satisfaction with the system.

Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| No Intervention: No text messages Patients in the non-intervention group will not receive any text messages. However, they will also receive the routine outpatient follow-up arrangements associated with attendance at an ED with self-harm including the provision of a contact phone number for the Samaritans. |
|
| Experimental: Supportive and interactive text messages We will deliver daily supportive and informative text messages for one month followed by one supportive and informative text message every other day the second month and then one weekly text message the third month to patients in the intervention group after they have been discharged from the ED following an episode of self-harm. Supportive text messages will mainly target relieving the patients of mood symptoms and providing them with strategies for dealing with suicidal thoughts while the informative ones will provide patients with a dedicated mobile phone number through which they can receive interactive support from the Samaritans. The text messages will encourage participants to text the Samaritans in times of crisis. Please see appendix I for examples of the relevant text messages. |
