Aggression-impulsivity, mental pain, and communication difficulties in medically serious and medically non-serious suicide attempters.

BACKGROUND: Unbearable mental pain, depression, and hopelessness have been associated with suicidal behavior in general, while difficulties with social communication and loneliness have been associated with highly lethal suicide attempts in particular. The literature also links aggression and impulsivity with suicidal behavior but raises questions about their influence on the lethality and outcome of the suicide attempt. OBJECTIVES: To evaluate the relative effects of aggression and impulsivity on the lethality of suicide attempts we hypothesized that impulsivity and aggression differentiate between suicide attempters and non-attempters and between medically serious and medically non-serious suicide attempters. METHOD: The study group included 196 participants divided into four groups: 43 medically serious suicide attempters; 49 medically non-serious suicide attempters, 47 psychiatric patients who had never attempted suicide; and 57 healthy control subjects. Data on sociodemographic parameters, clinical history, and details of the suicide attempts were collected. Participants completed a battery of instruments for assessment of aggression-impulsivity, mental pain, and communication difficulties. RESULTS: The medically serious and medically non-serious suicide attempters scored significantly higher than both control groups on mental pain, depression, and hopelessness (p<.001 for all) and on anger-in, anger-out, violence, and impulsivity (p<.05 for all), with no significant difference between the two suicide attempter groups. Medically serious suicide attempters had significantly lower self-disclosure (p<.05) and more schizoid tendencies (p<.001) than the other three groups and significantly more feelings of loneliness than the medically non-serious suicide attempters and nonsuicidal psychiatric patients (p<.05). Analysis of aggression-impulsivity, mental pain, and communication variables with suicide lethality yielded significant correlations for self-disclosure, schizoid tendency, and loneliness. The interaction between mental pain and schizoid traits explained some of the variance in suicide lethality, over and above the contribution of each component alone. CONCLUSIONS: Aggression-impulsivity and mental pain are risk factors for suicide attempts. However, only difficulties in communication differentiate medically serious from medically non-serious suicide attempters. The combination of unbearable mental pain and difficulties in communication has a magnifying effect on the risk of lethal suicidal behavior.

Mental pain, communication difficulties, and medically serious suicide attempts: a case-control study.

Medical severe suicide attempts (MSSA) are epidemiologically very similar to individuals who complete suicide. Thus the investigation of individuals who have made MSSAs may add to our understanding of the risk factors for completed suicide. The aim of this study was to assess the role of mental pain and communication difficulties in MSSA. A total of 336 subjects were divided into 4 groups: 78 meeting criteria for MSSA compared with116 subjects who made a medically non-serious suicide attempt (MNSSA), 47 psychiatric controls with no history of suicidal behavior, and 95 healthy controls. Mental pain variants (e.g., hopelessness), facets of communication difficulties (e.g., self-disclosure), as well as socio-demographic and clinical characteristics were assessed. The MSSA had significantly higher communication difficulties than the other 3 groups. Moreover, the interaction between mental pain and communication difficulties explained some of the variance in suicide lethality, above and beyond the contribution of each component alone. This report underlines the importance of mental pain for suicide attempts in general while difficulties in communication abilities play a critical role in differentiating MSSA from MNSSA. The co-existence of unbearable mental pain with difficulties in communication significantly enhances the risk for more lethal forms of suicidal behavior.
