Pharmacological interventions for self-harm in adults

Background
Self-harm (SH; intentional self-poisoning or self-injury) is common, often repeated, and strongly associated with suicide. This is an update of a broader Cochrane review on psychosocial and pharmacological treatments for deliberate SH, first published in 1998 and previously updated in 1999. We have now divided the review in to three separate reviews. This review is focused on pharmacological interventions in adults who self harm.
Objectives
To identify all randomised controlled trials of pharmacological agents or natural products for SH in adults, and to conduct meta-analyses (where possible) to compare the effects of specific treatments with comparison types of treatment (e.g., placebo/alternative pharmacological treatment) for SH patients.
Search methods
For this update the Cochrane Depression, Anxiety and Neurosis Review Group (CCDAN) Trials Search Co-ordinator searched the CCDAN Specialised Register (September 2014). Additional searches of MEDLINE, EMBASE, PsycINFO, and CENTRAL were conducted to October 2013.
Selection criteria
We included randomised controlled trials comparing pharmacological treatments or natural products with placebo/alternative pharmacological treatment in individuals with a recent (within six months) episode of SH resulting in presentation to clinical services.
Data collection and analysis
We independently selected trials, extracted data, and appraised trial quality. For binary outcomes, we calculated odds ratios (ORs) and their 95% confidence intervals (CIs). For continuous outcomes we calculated the mean difference (MD) and 95% CI. Meta-analysis was only possible for one intervention (i.e. newer generation antidepressants) on repetition of SH at last follow-up. For this analysis, we pooled data using a random-effects model. The overall quality of evidence for the primary outcome was appraised for each intervention using the GRADE approach.
Main results
We included seven trials with a total of 546 patients. The largest trial included 167 participants. We found no significant treatment effect on repetition of SH for newer generation antidepressants (n = 243; k = 3; OR 0.76, 95% CI 0.42 to 1.36; GRADE: low quality of evidence), low-dose fluphenazine (n = 53; k = 1; OR 1.51, 95% CI 0. 50 to 4.58; GRADE: very low quality of evidence), mood stabilisers (n = 167; k = 1; OR 0.99, 95% CI 0.33 to 2.95; GRADE: low quality of evidence), or natural products (n = 49; k = 1; OR 1.33, 95% CI 0.38 to 4.62; GRADE: low quality of evidence). A significant reduction in SH repetition was found in a single trial of the antipsychotic flupenthixol (n = 30; k = 1; OR 0.09, 95% CI 0.02 to 0.50), although the quality of evidence for this trial, according to the GRADE criteria, was very low. No data on adverse effects, other than the planned outcomes relating to suicidal behaviour, were reported.
Authors’ conclusions
Given the low or very low quality of the available evidence, and the small number of trials identified, it is not possible to make firm conclusions regarding pharmacological interventions in SH patients. More and larger trials of pharmacotherapy are required. In view of an indication of positive benefit for flupenthixol in an early small trial of low quality, these might include evaluation of newer atypical antipsychotics. Further work should include evaluation of adverse effects of pharmacological agents. Other research could include evaluation of combined pharmacotherapy and psychological treatment.

Interventions for self-harm in children and adolescents

Background : Self-harm(SH; intentional self-poisoning or self-injury) is common in children and adolescents, often repeated, and strongly associated with suicide. This is an update of a broader Cochrane review on psychosocial and pharmacological treatments for deliberate SH first published in 1998 and previously updated in 1999. We have now divided the review into three separate reviews; this review is focused on psychosocial and pharmacological interventions for SH in children and adolescents.

Objectives : To identify all randomised controlled trials of psychosocial interventions, pharmacological agents, or natural products for SHin children and adolescents, and to conduct meta-analyses (where possible) to compare the effects of specific treatments with comparison types of treatment (e.g., treatment as usual (TAU), placebo, or alternative pharmacological treatment) for children and adolescents who SH.

Search methods : For this update the Cochrane Depression, Anxiety and Neurosis Group (CCDAN) Trials Search Co-ordinator searched the CCDAN Specialised Register (30 January 2015).

Selection criteria : We included randomised controlled trials comparing psychosocial or pharmacological treatments with treatment as usual, alternative treatments, or placebo or alternative pharmacological treatment in children and adolescents (up to 18 years of age) with a recent (within six months) episode of SH resulting in presentation to clinical services.

Self-cutting and prospective repetition of self-harm: studies of emergency department presentations in Ireland

Background Self-harm places an individual at increased risk of future self-harm and suicide, and indicates distress and maladaptive coping. Those who present to hospital with self-cutting form a significant minority of self-harm patients who are at increased risk of prospective repetition of self-harm and suicide compared with those presenting with intentional overdose. In addition to increased risk, there is emerging evidence of demographic, psychological, clinical, and social differences between those presenting with self-cutting and those presenting with overdose. Aim and Key Objectives The aim of the current doctoral work was to examine in detail the association between presenting with self-cutting and risk of prospective repetition. The objectives were: to identify evidence-based risk factors for repetition of self-harm among those presenting to emergency departments with self-harm; to compare demographic and presentation characteristics and prospective repetition across presentations of self-cutting only, self-cutting plus intentional overdose, and intentional overdose only; to compare prospective repetition and other characteristics within self-cutting presentations based on the type of treatment received; to compare self-cutting and intentional overdose patients on psychological risk and protective factors for repetition; and to examine the lived experience of engaging in repeated overdose and self-cutting. Methods The current doctoral work used a mixed-methods approach and is comprised of one systematic review and four empirical studies. The empirical studies were two registry-based prospective studies of Irish hospital presentations of self-harm, one prospective structured interview study, and one qualitative study using Interpretative Phenomenological Analysis. Results The systematic review identified several consistent and emerging risk factors for repetition of self-harm, compared to which self-cutting had a medium-sized effect. The registry studies demonstrated that the involvement of self-cutting, particularly less medically severe selfcutting, confers an increased risk of 1-month and 12-month repetition among Irish index selfharm presentations. The structured psychological study detected higher hopelessness and lower non-reactivity to inner experience among those presenting with self-cutting, and higher depression among those who repeated self-harm. Repeaters had lower baseline levels of protective psychological factors than non-repeaters and continued to have higher depression and hopelessness at follow-up. Finally, the qualitative study indicated that self-harm is a purposeful action taken in response to an overwhelming situation and is evaluated afterwards in terms of personal and social effects. Chosen method of self-harm seemed to be influenced by the desired outcome of the self-harm act, capability, accessibility and previous experience. Conclusion Despite limitations in terms of recruitment rates, the work presented in this thesis is innovative in examining the issue of the association between self-cutting and repetition from multiple perspectives. No one factor can reliably predict all repetition but self-cutting represents one consistent and easily detected risk factor for repetition. Those who present with self-cutting exhibit significant differences on demographic, clinical, and psychological variables compared with those presenting with intentional overdose, and seem to exhibit a more vulnerable profile. However, those who present with self-cutting do not form a discrete or homogenous group, and self-harm methods and levels of suicidal intent are liable to fluctuate over time.

Factors associated with self-cutting as a method of self-harm: findings from the Irish National Registry of Deliberate Self-Harm

Background: Research suggests that patients presenting to hospital with self-cutting differ from those with intentional overdose in demographic and clinical characteristics. However, large-scale national studies comparing self-cutting patients with those using other self-harm methods are lacking. We aimed to compare hospital-treated self-cutting and intentional overdose, to examine the role of gender in moderating these differences, and examine the characteristics and outcomes of those patients presenting with combined self-cutting and overdose. Methods: Between 2003 and 2010, the Irish National Registry of Deliberate Self-Harm recorded 42,585 self-harm presentations to Irish hospital emergency departments meeting the study inclusion criteria. Data were obtained on demographic and clinical characteristics by independent data registration officers. Results: Compared with overdose only, involvement of self-cutting (with or without overdose) was significantly more common in males than females, with an overrepresentation of males aged <35 years. Independent of gender, involvement of self-cutting (with or without overdose) was significantly associated with younger age, city residence, repetition within 30 days and repetition within a year (females only). Factors associated with self-cutting as the sole method were no fixed abode/living in an institution, presenting outside 9 a.m. to 5 p.m., not consuming alcohol and repetition between 31 days and 1 year (males only). Conclusion: The demographic and clinical differences between self-harm patients underline the presence of different subgroups with implications for service provision and prevention of repeated self-harm. Given the relationship between self-cutting and subsequent repetition, service providers need to ensure that adequate follow-up arrangements and supports are in place for the patient.

Risk of repeated self-harm and associated factors in children, adolescents and young adults

Background: Repeated self-harm represents the single strongest risk factor for suicide. To date no study with full national coverage has examined the pattern of hospital repeated presentations due to self-harm among young people. Methods: Data on consecutive self-harm presentations were obtained from the National Self-Harm Registry Ireland. Socio-demographic and behavioural characteristics of individuals aged 10–29 years who presented with self-harm to emergency departments in Ireland (2007–2014) were analysed. Risk of long-term repetition was assessed using survival analysis and time differences between the order of presentations using generalised estimating equation analysis. Results: The total sample comprised 28,700 individuals involving 42,642 presentations. Intentional drug overdose was the most prevalent method (57.9%). Repetition of self-harm occurred in 19.2% of individuals during the first year following a first presentation, of whom the majority (62.7%) engaged in one repeated act. Overall, the risk of repeated self-harm was similar between males and females. However, in the 20–24-year-old age group males were at higher risk than females. Those who used self-cutting were at higher risk for repetition than those who used intentional drug overdose, particularly among females. Age was associated with repetition only among females, in particular adolescents (15–19 years old) were at higher risk than young emerging adults (20–24 years old). Repeated self-harm risk increased significantly with the number of previous self-harm episodes. Time differences between first self-harm presentations were detected. Time between second and third presentation increased compared to time between first and second presentation among low frequency repeaters (patients with 3 presentations only within 1 year following a first presentation). The same time period decreased among high frequency repeaters (patients with at least 4 to more than 30 presentations). Conclusion: Young people with the highest risk for repeated self-harm were 15–19-year-old females and 20–24-year-old males. Self-cutting was the method associated with the highest risk of self-harm repetition. Time between first self-harm presentations represents an indicator of subsequent repetition. To prevent risk of repeated self-harm in young people, all individuals presenting at emergency departments due to self-harm should be provided with a risk assessment including psychosocial characteristics, history of self-harm and time between first presentations.

Vulnerability or resilience? Psycho-social factors associated with deliberate self-harm among adolescents

Background: Deliberate self-harm (DSH) is common among adolescents in Ireland and internationally. Psychological factors, negative life events and lifestyle factors have been found to be associated with self-harm in this group. However, large scale population-based studies of adolescent selfharm and its correlates have been lacking, and internationally a standardised methodology was needed to facilitate comparative studies. The focus on vulnerability which has been prevalent in this field has meant that research has failed to examine resilient adaptation among at-risk adolescents. Method: Data were obtained from a cross-sectional school-based study conducted in Ireland and in each of the six other centres which participated in the Child and Adolescent Self-harm in Europe (CASE) study. In Ireland, 3,881 adolescents in 39 schools in completing the anonymous questionnaire, while across all 7 centres, over 30,000 young people participated. Data were gathered on health and lifestyle, self-harm thoughts and behaviour, a wide range of life events, psychological characteristics (anxiety and depressive symptoms, self-esteem, impulsivity and coping style), and support available to young people. Results: This thesis reports the findings of the Irish CASE centre as well as one international study. The factors associated with DSH among Irish adolescents differed by gender, but among both genders drug use and knowing a friend who had engaged in self-harm were associated with DSH. Among Irish boys, strong associations were found between bullying and poor mental health and DSH. Among boys who had been bullied, psychological and school factors were associated with DSH, while family support was protective. Links between stressful life events, psychological characteristics and DSH within the international CASE sample were examined. Increased history of self-harm thoughts and acts was associated with greater depression, anxiety and impulsivity, lower self esteem and an increased prevalence of ten different negative life events, supporting the hypothesis of a “dose-response” relationship between these risk factors and the self-harm process. Associations between coping style, mental health factors (depressive symptoms, anxiety and self-esteem) and self-harm were examined among Irish adolescents. Emotion-oriented coping was strongly associated with poorer mental health and self-harm thoughts and acts. A mediating effect of emotion-oriented coping on associations between mental health factors and DSH was found for both genders and between problem-oriented coping and mental health factors for girls. Similar mediating effects of coping style were found when risk of self-harm thoughts was examined. Resilient adaptation among adolescents exposed to suicidal behaviour of others was examined. Self-harm thoughts were common in these adolescents. Among those exposed to suicidal behaviour of others, vulnerability factors were drug use and higher levels of anxiety among boys, while for girls drug use, bullying and abuse were vulnerability factors, while resilience was associated with higher self-esteem and use of problem-oriented coping. Conclusion: These findings can aid in the identification of young people at risk of self-harm in the school setting and highlight the importance of mental health, peer-related and lifestyle factors in the development of DSH. High-risk groups of young people such as bullying victims and those exposed to suicidal behaviour of others have distinctive profiles of risk factors which differ from those of their peers. Findings relating to the importance of positive coping skills can inform positive mental health programmes, many of which aim to enhance life skills and build resilience among young people. Knowledge of the factors associated with positive adaptation among at-risk adolescents can inform prevention efforts among this group.

Anger, aggression, and self-harm in PTSD and complex PTSD

This study examined the contribution of complex posttraumatic stress disorder (PTSD) diagnosis and symptomatology to the difficulties of anger, aggression, and self-harm in a Northern Ireland clinical community sample. A "current complex PTSD" (CCPTSD) group (n = 11) was compared with a "current PTSD" group (n = 31) on self-report measures of these variables. The CCPTSD group demonstrated significantly higher levels of physical aggression and selfharm than the PTSD group. The complex PTSD symptom of 'alterations in self-perception' was a significant predictor of aggression and history of self-harm, suggesting the potential role of posttraumatic shame and self-loathing in PTSD theoretical models of these destructive behaviors. Social desirability was a notable confounding influence in the assessment of anger, aggression, and self-harm in traumatised individuals.

Trauma typology as a risk factor for aggression and self-harm in a complex PTSD population: The mediating role of alterations in self-perception

This study examined the role of prolonged, repeated traumatic experiences such as childhood and sectarian trauma in the development of posttraumatic aggression and self-harm. Forty-four adult participants attending therapy for complex trauma in Northern Ireland were obtained via convenience sampling. When social desirability was controlled, childhood emotional and physical neglect were significant correlates of posttraumatic hostility and history of self-harm. These relationships were mediated by alterations in self-perception (e.g., shame, guilt). Severity of sectarian-related experiences was not related to self-destructive behaviors. Moreover, none of the trauma factors were related to overt aggressive behavior. The findings have implications for understanding risk factors for posttraumatic aggression and self-harm, as well as their treatment. © 2013 Copyright Taylor & Francis Group, LLC.
