Theoretical Models Of Suicide Research Articles

An experimental investigation of the influence of loneliness on changes in belongingness and desire to escape.

ObjectiveLoneliness is a well‐established risk factor for suicide in young adults, but the mechanisms involved are still unclear. Drawing on the Interpersonal Theory of Suicide, the Evolutionary Model of Loneliness, and Prospect Theory, we examined if high and low levels of loneliness are associated with different patterns of response to losses or gains of belongingness.MethodsA sample of 188 students completed the UCLA‐Loneliness scale (version 3) and measures of suicide risk. Participants in the top and bottom tertiles of loneliness scores completed a computerized task designed to induce changes (gains, losses) or consistency in risk factors for suicide (belongingness, burdensomeness) over time, and examined the effect on desire to quit the task.ResultsThe results showed that the high loneliness group exhibited a larger magnitude of effect on desire to quit from gaining belongingness than for losing belongingness. In contrast, the low loneliness group showed a larger change in desire to quit from losing belongingness than gaining belongingness.ConclusionThe findings provide preliminary experimental support for distinct profiles of suicide risk based on prevailing levels of loneliness. The findings are discussed in relation to a need for increased precision in theoretical models of suicide and loneliness.

Suicide Models and Treatment Models Are Separate Entities. What Does It Mean for Clinical Suicide Prevention?

Theoretical models of suicide are based on risk factors associated with suicide, such as psychiatric pathology, genetics, epigenetics, functional brain disorders, and impaired decision making. In current clinical practice, the predominant risk model is the medical model, which posits that treating suicide risk is primarily a matter of treating psychiatric disorders. However, even comprehensive risk factor models cannot overcome the basic problem that, by their nature, they cannot accommodate the suicidal person’s psychological experience of suicidality. Risk factor models do not translate into effective treatment models. Suicide risk is highly personal and fluid, and is related to individual vulnerabilities and to person-specific events triggering suicidal thoughts and actions. Clinicians need treatment models that are meaningful to suicidal patients. Understanding the single person’s suicidality requires a patient-centered approach. Therapeutic interventions that effectively reduce the risk of suicidal behavior have been developed from general principles of psychotherapy. Therapy process factors associated with effective therapies are working alliance, validation of the individual patient’s thoughts and feelings, active treatment engagement. Psychological therapies need patients who are active participants in a collaborative working relationship between therapist and patient. The goal must be to jointly develop a meaningful understanding of the suicidal crisis. In view of the limited personal resources in health care systems it is important that effective therapies are brief and effective. Future research must aim to improve our understanding of the factors involved in effective therapies in order to optimize treatments for individuals at risk. This may also include the integration of biological risk factors in psychological treatment models.

A Theory-Based Longitudinal Investigation Examining Predictors of Self-Harm in Adolescents With and Without Bereavement Experiences.

BackgroundResearch has demonstrated that exposure to suicide can lead to increased vulnerability for self-harm or suicide. As a result, ideation-to-action models of suicide (e.g., the Integrated Motivational-Volitional Model of Suicide; IMV) recognise exposure as a significant risk factor which may be implicated in the translation of thoughts into actions. However, few studies have tested this theoretical link explicitly within an adolescent population, and examined how it compares to other types of bereavements.MethodsA 6-month prospective questionnaire study was conducted with 185 Scottish adolescents aged 11–17 (115 adolescents also completed the questionnaire at follow-up). The questionnaire included measures on experiences with bereavement and lifetime engagement in self-harm, as well as measures of defeat, entrapment, social support, coping, and other psychological variables.ResultsAt baseline, 11% of young people reported exposure to a suicide death, and 62% to a non-suicide death. In addition, 21% of pupils reported ever engaging in self-harm, while 24% had experienced self-harm ideation without engaging in it. Cross-sectional multivariate logistic regressions showed that maladaptive coping, family social support, glorifying/normalising beliefs about suicide, and family self-harm were significantly associated with self-harm group membership (control, ideation, or enactment groups). At follow-up, 9% of pupils reported exposure to a suicide death and 11% to a non-suicide death for the first time. A total of 29% of the sample reported self-harm at T2 (8% of participants for the first time), and 23% reported self-harm ideation without engaging in it. Multivariate analyses found that stigmatising beliefs about suicide, glorifying/normalising beliefs about suicide, and self-harm ideation at baseline were the only variables to predict self-harm group membership prospectively. Bereavement experiences, whether by suicide or non-suicide, did not predict self-harm group status at baseline nor at follow-up.ConclusionsThis study provides support for the validity of a theoretical model of suicide, even though predictive ability over the 6-months period was limited. Although difficulties with recruitment may have limited the statistical power, this study provides insight into the prevalence and experiences of suicide bereavement among adolescents and the factors related to the onset and maintenance of self-harm.

EXPOSURE TO WORKPLACE BULLYING AND SUICIDAL IDEATION: AN EXPLORATORY STUDY

There is evidence of the effects of exposure to workplace bullying on victims who may manifest symptoms of depression, anxiety, burnout, somatization, sleep difficulties, and posttraumatic stress; however, few studies have examined the impact of workplace bullying on suicidal ideation. The purpose of the present study was to examine the relationship between exposure to workplace bullying and suicidal ideation and how feelings of defeat and entrapment mediate this relationship. Also, it was intended to examine how rumination moderates this relationship. As a framework, it was used the Integrated Motivational-Volitional Model of Suicide Behavior (IMV) in which has been integrated several theoretical models of suicide. A total of 898 employed subjects participated in this cross-sectional design study. To examine the hypotheses, PLS-SEM model was used using the SMART-PLS program. Exposure to workplace bullying,defeat and entrapment were positively and significantly related to suicidal ideation. Meanwhile,feelings of defeat and entrapment mediated the relationship between exposure to workplace bullying and suicidal ideation and rumination moderated the relation between exposure to workplace bullying and feelings defeat. The results of the present study have both theoretical and practical implications, among which we can mention that results support and expand the IMV model of suicidal behavior. The exposure to workplace bullying brings a challenge for the psychologists in the occupational health context, and human resources practitioners in the management of this phenomenon in organizations to prevent it and in a worst case scenario, to respond in an effective manner due to its individual and organizational impact.

A review on theoretical models of suicide

Suicide is a major public health issue which is highly complex and multifaceted. Subsequently, after the pioneering work of Durkheim and Freud, researchers and scholars have attempted to explain the biological, social, and psychological nature of suicide. The present work presents an overview of different theoretical models underlying the development of suicidal behaviour. Hence the theory components will be a better understanding of the causal mechanisms of suicide and it will lead to improving the intervention strategies for suicidal behaviours.

Rethinking pathways to completed suicide by female prisoners

Purpose – The purpose of this paper is to explore the role of trauma experience in pathways to self-harm or attempted suicide in female prisoners who died through self-inflicted death in England and Wales. Design/methodology/approach – Quantitative study using the Prison and Probation Ombudsmen’s independent reports on deaths in custody. In total, 32 cases of female self-inflicted death in custody were coded on the presence of direct or interpersonal trauma, presence of superficial self-harm (SSH), near-lethal self-harm (NLSH), suicide attempts and recent significant life event. The number of previous suicide attempts (PSAs) and age at time of death was recorded. Findings – Direct trauma is linked with repeated suicide attempts but recued the likelihood of SSH prior to suicide. Neither interpersonal trauma nor age increased likelihood of pre-suicide behaviours. NLSH was not predicted by either traumatic experience. Amongst these completed suicide cases, 56 per cent were not reported as having experienced trauma, 46 per cent had no recorded PSAs and 12 per cent also had no previous self-harm reported. Research limitations/implications – The small sample limited statistical power and specificity of classifications. Provides support for direct trauma in developing capacity for repeated suicidal behaviour as indicated in theoretical models of suicide (Joiner, 2005; O’Connor, 2011). Practical implications – Different pathways to suicide likely to exist for female prisoners and importance of trauma intervention services. Originality/value – Using cases of completed suicide in female prisoners to investigate the pathway to suicide from trauma through previous self-harm and attempted suicide.

Predicting future suicide attempts among depressed suicide ideators: A 10-year longitudinal study

Suicidal ideation and attempts are a major public health problem. Research has identified many risk factors for suicidality; however, most fail to identify which suicide ideators are at greatest risk of progressing to a suicide attempt. Thus, the present study identified predictors of future suicide attempts in a sample of psychiatric patients reporting suicidal ideation. The sample comprised 49 individuals who met full DSM-IV criteria for major depressive disorder and/or dysthymic disorder and reported suicidal ideation at baseline. Participants were followed for 10 years. Demographic, psychological, personality, and psychosocial risk factors were assessed using validated questionnaires and structured interviews. Phi coefficients and point-biserial correlations were used to identify prospective predictors of attempts, and logistic regressions were used to identify which variables predicted future attempts over and above past suicide attempts. Six significant predictors of future suicide attempts were identified – cluster A personality disorder, cluster B personality disorder, lifetime substance abuse, baseline anxiety disorder, poor maternal relationship, and poor social adjustment. Finally, exploratory logistic regressions were used to examine the unique contribution of each significant predictor controlling for the others. Comorbid cluster B personality disorder emerged as the only robust, unique predictor of future suicide attempts among depressed suicide ideators. Future research should continue to identify variables that predict transition from suicidal thoughts to suicide attempts, as such work will enhance clinical assessment of suicide risk as well as theoretical models of suicide.

The cultural theory and model of suicide

A growing body of research has demonstrated important variations in the prevalence, nature, and correlates of suicide across ethnic and sexual minority groups. Despite these developments, existing clinical and research approaches to suicide assessment and prevention have not incorporated cultural variations in any systematic way. In addition, theoretical models of suicide have been largely devoid of cultural influence. The current report presents a comprehensive analysis of literature describing the relationship between cultural factors and suicide in three major ethnic groups (African Americans, Asian Americans, and Latinos) and LGBTQ11“LGBTQ” populations are also referred to as “sexual minorities.” LGBTQ is an abbreviation for lesbian, gay, bisexual, and transgender or transsexual individuals, and people questioning their sexual orientation. sexual minority groups. We utilized an inductive approach to synthesize this variegated body of research into four factors that account for 95% of existing culturally specific risk data: cultural sanctions, idioms of distress, minority stress, and social discord. These four cultural factors are then integrated into a theoretical framework: the Cultural Model of Suicide. Three theoretical principles emerge: (1) culture affects the types of stressors that lead to suicide; (2) cultural meanings associated with stressors and suicide affect the development of suicidal tendencies, one's threshold of tolerance for psychological pain, and subsequent suicidal acts; and (3) culture affects how suicidal thoughts, intent, plans, and attempts are expressed. The Cultural Model of Suicide provides an empirically guided cohesive approach that can inform culturally competent suicide assessment and prevention efforts in future research and clinical practice. Including both ethnic and sexual minorities in our investigations ensures advancement along a multiple identities perspective.

Therapist Sensitivity Towards Emotional Life-career Issues and the Working Alliance with Suicide Attempters

This study investigated the usefulness of an action theoretical model of suicide in interviewing suicide attempters. Eighteen interviews were video-recorded and transcribed. The patients’ narratives were reconstructed and life-career issues relevant for the patient's suicidality formulated. Skin conductance response was used to determine narrative content associated with actualized emotions. Scores of the patients’ ratings of helping alliance experienced in the interview were positively associated with the therapists’ sensitivity towards emotionally relevant life-career issues. Furthermore, relationship satisfaction was related to a narrative interviewing style. We conclude that working alliance in clinical interviews with suicide attempters can be improved when the interviewer uses apatient-oriented approach aimed at understanding the patient's suicidality in the context of personal life-career, or identity issues.
