The integrated motivational–volitional model of suicidal behaviour

Suicide is a major public health concern accounting for 800 000 deaths globally each year. Although there have been many advances in understanding suicide risk in recent decades, our ability to predict suicide is no better now than it was 50 years ago. There are many potential explanations for this lack of progress, but the absence, until recently, of comprehensive theoretical models that predict the emergence of suicidal ideation distinct from the transition between suicidal ideation and suicide attempts/suicide is key to this lack of progress. The current article presents the integrated motivational–volitional (IMV) model of suicidal behaviour, one such theoretical model. We propose that defeat and entrapment drive the emergence of suicidal ideation and that a group of factors, entitled volitional moderators (VMs), govern the transition from suicidal ideation to suicidal behaviour. According to the IMV model, VMs include access to the means of suicide, exposure to suicidal behaviour, capability for suicide (fearlessness about death and increased physical pain tolerance), planning, impulsivity, mental imagery and past suicidal behaviour. In this article, we describe the theoretical origins of the IMV model, the key premises underpinning the model, empirical tests of the model and future research directions

Intrapersonal positive future thinking predicts repeat suicide attempts in hospital-treated suicide attempters

Objective: Although there is clear evidence that low levels of positive future thinking (anticipation of positive experiences in the future) and hopelessness are associated with suicide risk, the relationship between the content of positive future thinking and suicidal behavior has yet to be investigated. This is the first study to determine whether the positive future thinking–suicide attempt relationship varies as a function of the content of the thoughts and whether positive future thinking predicts suicide attempts over time. Method: A total of 388 patients hospitalized following a suicide attempt completed a range of clinical and psychological measures (depression, hopelessness, suicidal ideation, suicidal intent and positive future thinking). Fifteen months later, a nationally linked database was used to determine who had been hospitalized again after a suicide attempt. Results: During follow-up, 25.6% of linked participants were readmitted to hospital following a suicide attempt. In univariate logistic regression analyses, previous suicide attempts, suicidal ideation, hopelessness, and depression—as well as low levels of achievement, low levels of financial positive future thoughts, and high levels of intrapersonal (thoughts about the individual and no one else) positive future thoughts predicted repeat suicide attempts. However, only previous suicide attempts, suicidal ideation, and high levels of intrapersonal positive future thinking were significant predictors in multivariate analyses. Discussion: Positive future thinking has predictive utility over time; however, the content of the thinking affects the direction and strength of the positive future thinking–suicidal behavior relationship. Future research is required to understand the mechanisms that link high levels of intrapersonal positive future thinking to suicide risk and how intrapersonal thinking should be targeted in treatment interventions

Differentiating adults who think about self-harm from those who engage in self-harm: the role of volitional alcohol factors

Background: Self-harm, an act of self-poisoning or self-injury irrespective of motivation, is a major public health concern. Use of alcohol prior to or alongside acts of self-harm is common but little is known about the alcohol-related mechanisms of self-harm enaction. We utilised an ideation-to-action approach to clarify the extent to which volitional alcohol factors differentiated those who have thoughts of self-harm but do not act on them (self-harm ideation) and those who engage in self-harm (self-harm enaction). Methods: Cross-sectional analyses of the baseline phase of the Health Lifestyle and Wellbeing study: 1546 adults (1079 female; Mean age = 34 y; 92% White) resident in Scotland completed measures of demographics, lifetime self-harm, volitional alcohol factors and psychosocial factors. Multinomial logistic regression compared those with a history of self-harm thoughts (‘ideation’, n = 297), self-harm acts (‘enaction’, n = 346) and ‘controls’ (n = 897) to identify volitional alcohol factors associated with self-harm enaction. Results: Volitional alcohol factors differentiated those with a history of self-harm enaction from those with a history of self-harm ideation (as well as those with no history) in initial models adjusted for demographics and depressive symptoms: the self-harm enaction group reported stronger alcohol-related negative urgency (OR = 1.74, 95% CI 1.41–2.16, p < .001), more frequent heavy drinking (OR = 1.46, 95% CI 1.24–1.72, p < .001) and stronger expectancies that drinking alcohol leads to negative self-perceptions (OR = 1.33, 95% CI 1.03–1.72, p = 0.03) and markers of self-harm risk (OR = 1.64, 95% CI 1.18–2.30, p = 0.004). Alcohol-related negative urgency and heavy-drinking frequency continued to differentiate those in the self-harm enaction group from those in ideation group in multivariate models. Consistent with theoretical models positing phase-specific moderators of self-harm ideation and enaction, psychosocial factors (perceived stress, support, negative mood regulation expectancies) differentiated those with a history of self-harm ideation from those without but not those in the ideation and enaction groups. Conclusions: Management of self-harm risk requires better understanding of alcohol-related mechanisms of self-harm enaction. Volitional alcohol factors may play a role in governing the translation of self-harm thoughts into self-harm acts

Pain and self-harm: A systematic review

Background  A growing body of research has explored altered physical pain threshold and tolerance in non-suicidal self-injury (NSSI) and suicidal self-harm. The evidence, however, is inconsistent such that the nature of the relationship is unclear, and whether or not this effect is also present in suicidal self-harm is equivocal.  Methods  A keyword search of three major psychological and medical databases (PsycINFO, Medline and Web of Knowledge) was conducted, yielding 1,873 records. Following duplicate removal and screening, 25 articles were quality assessed, and included in the final systematic review.  Results  There is strong evidence for increased pain tolerance in NSSI, and some evidence for this in suicidal individuals, but notably, there were no prospective studies. The review found a lack of substantive focus on psychological correlates of altered pain tolerance in this population. Several candidate explanatory mechanisms were proposed within the reviewed studies.  Limitations  The current review was a narrative systematic review; methods used to assess pain were considered too heterogeneous to conduct a meta-analysis.  Conclusions  The evidence suggests that there is elevated pain tolerance among those who engage in NSSI. Future prospective research should determine if altered pain tolerance is a cause or a consequence of the behaviour. The identification of psychological correlates of increased pain tolerance is a neglected area of research. It could provide opportunities for treatment/intervention development, if mediating or moderating pathways can be identified. Too few studies have directly investigated candidate explanatory mechanisms to draw definitive conclusions

An exploratory randomised trial of a simple, brief psychological intervention to reduce subsequent suicidal ideation and behaviour in patients admitted to hospital for self-harm.

Background Implementation intentions link triggers for self-harm with coping skills and appear to create an automatic tendency to invoke coping responses when faced with a triggering situation. Aims To test the effectiveness of implementation intentions in reducing suicidal ideation and behaviour in a high-risk group. Method Two hundred and twenty-six patients who had self-harmed were randomised to: (a) forming implementation intentions with a ‘volitional help sheet’; (b) self-generating implementation intentions without help; or (c) thinking about triggers and coping, but not forming implementation intentions. We measured self-reported suicidal ideation and behaviour, threats of suicide and likelihood of future suicide attempt at baseline and then again at the 3-month follow-up. Results All suicide-related outcome measures were significantly lower at follow-up among patients forming implementation intentions compared with those in the control condition (ds>0.35). The volitional help sheet resulted in fewer suicide threats (d = 0.59) and lowered the likelihood of future suicide attempts (d = 0.29) compared with patients who self-generated implementation intentions. Conclusions Implementation intention-based interventions, particularly when supported by a volitional help sheet, show promise in reducing future suicidal ideation and behaviour

An investigation of the factor structure of the Self-Compassion Scale

The Self-Compassion Scale (SCS) is the most widely used measure of self-compassion. The scale is constructed of six factors measuring positive and negative components of compassion. Support for this factor structure has been subject to debate and alternative factor structures have been proposed. We tested the proposed factor structures against existing models of the SCS including one derived from an exploratory factor analysis of our data. Respondents (n = 526) completed the original version of the SCS online at two time points, at baseline (time 1) and 2.5 months later (n = 332, time 2). Exploratory factor analysis (EFA) was carried out on time 1 data and confirmatory factor analyses (CFA) were conducted on time 2 data and retested using time 1 data. The EFA yielded a five-factor model. CFA was used to compare the following models: Neff’s original six-factor correlated and higher-order models; a single-factor, two-factor, five-factor model (as suggested by the EFA) and a bi-factorial model. The bi-factorial model was the best fit to the data followed by the six-factor correlated model. Omega indices were calculated and yielded support for the bi-factorial model of SCS. In conclusion, this study supports the use of the six-factor scoring method of the SCS and the use of an overarching self-compassion score

The role of physical and mental multimorbidity in suicidal thoughts and behaviours in a Scottish population cohort study

Background: Physical illness and mental disorders play a significant role in fatal and non-fatal suicidal behaviour. However, there is no clear evidence for the effect of physical and mental illness co-occurrence (multimorbidity) in suicidal ideation and attempts. The aim of the current study was to investigate, whether physical/mental health multimorbidity predicted suicidal thoughts and behaviours as outcomes. Methods: Data from the West of Scotland Twenty-07 cohort were analysed. Twenty-07 is a multiple cohort study following people for 20 years, through five waves of data collection. Participants who responded to past-year suicidal thoughts and suicide attempt items were grouped into four distinct health-groups based on having: (1) neither physical nor mental health condition (controls); (2) one or more physical health condition; (3) one or more mental health condition and; (4) multimorbidity. The role of multimorbidity in predicting suicidal ideation and suicide attempts was tested with a generalised estimating equation (GEE) model and odds ratios (ORs) and 95% CIs are presented. Whether the effect of multimorbidity was stronger than either health condition alone was also assessed. Results: Multimorbidity had a significant effect on suicidal thoughts and suicide attempts, compared to the control group, but was not found to increase the risk of either suicide-related outcomes, more than mental illness alone. Conclusions: We identified an effect of physical/mental multimorbidity on risk of suicidal thoughts and suicide attempts. Considering that suicide and related behaviour are rare events, future studies should employ a prospective design on the role of multimorbidity in suicidality, employing larger dataset

Trends in Self-Harm in Kuala Lumpur, 2005-2011.

Acts of self-harm are not routinely tracked in Malaysia. The present study investigates the prevalence of self-harm in Kuala Lumpur, Malaysia, over a 7-year period. The aims were to: (a) assess the prevalence of self-harm; (b) examine any changes over a period of 7 years, and (c) identify correlates of methods of self-harm. Data were extracted from the hospital records of Kuala Lumpur Hospital to review trends in self-harm between 2005 and 2011. There were 918 episodes of self-harm across the 7-year period, with a significant peak in 2007-2009. The average rate of self-harm (7.7 per 100,000 population per year) was similar or lower than the rate of suicide (6-8 or 8-13 per 100,000) suggesting that genuine cases of self-harm are often attributed to other causes. Nevertheless, over-representation of young people, women and Indians suggest areas in which resources to prevent self-harm might usefully be targeted. Estimating rates of self-harm are fraught with problems and further research is needed to understand the economic and cultural barriers around seeking treatment for self-harm, reporting self-harm and classifying self-harm
