« Background. In contrast with the large amount of research on the familial transmission of antisocial behaviour, few studies have investigated similarity between spouses for such behaviour. In addition, none of these studies have examined child conduct disorder (CCD) and adult antisocial behaviour (AAB) separately. Method. We studied 519 pairs of spouses who completed the Diagnostic Interview Schedule. In each pair, one spouse belonged to a random subsample of persons who had participated in a large population survey and was re-interviewed. Association between spouses for lifetime symptoms and DSM-III criteria of CCD, AAB, antisocial personality disorder and co-morbid psychiatric diagnoses was examined with bivariate and multivariate logistic regression analyses. Results. We observed a moderate association between spouses for the presence of CCD (OR=4.02, 95% CI=2.03–7.96), and a strong association for the presence of AAB (OR=20.1, 95% CI=5.97–67.5). This similarity for AAB was independent of the similarity for CCD and persisted after adjustment for spousal similarity for disorders co-morbid with AAB. An examination of the relationship between marital status and the presence of CCD and/or AAB in the general population sample (from which originated our sample of couples) suggested that the spousal similarity for AAB was more likely attributable to assortative mating rather than marital contamination. Conclusion. Our finding of a strong similarity between spouses for AAB has significant implications for both clinicians and researchers. It also suggests that adult antisocial behaviour should be considered as a distinct diagnostic entity, an approach which diverges from DSM-IV diagnostic criteria. »

Intentions : « This study aimed to identify factors that contribute to this high incidence of attempted suicide, and to provide information to serve as a guide for preventive measures. » (p. 9)
Échantillon/Matériau : « The study subjects were 99 Inuit adolescents and young adults, between the ages of 14 and 25 years at the time of interview, who were residing in a village in the Artic of Quebec. » (p. 9)
Instruments : - Adaptation of the Adolescent Health Survey undertaken in 1988 by the Indian Public Health Service in the United States; - Self-perceived health was assessed with the question: What is your state of health? with four possible response categories; - An index of crowded housing was constructed by dividing the number of people living in the respondent’s dwelling by the number of bedrooms; - Suicidal ideation and attempts were assessed with the following questions: have you ever thought of committing suicide? and have you ever tried to commit suicide?; - Alienation: The scale used to measure alienation from family and community was adapted from the 9-item scale of Grossman et al.; - Substance use index; - DSM-IV.

« The prevalence of and risk factors for attempted suicide and suicidal ideation were examined with a survey of 99 Inuit, aged 14-25 years, residing in a community in Northern Quebec. A total of 34% of survey respondents reported a previous suicide attempt, and 20% had attempted suicide more than once. A suicide attempt had resulted in injury in about 11% of those surveyed. The prevalence of suicidal ideation was also very high: 43% of subjects reported past thoughts of suicide, and 26% had had suicidal thoughts during the month before the survey. Risk factors for suicide attempts included male gender, having a friend who had attempted or committed suicide, a history of being physically abused, a history of solvent abuse, and having a parent with an alcohol or drug problem. Protective factors included a family history of having received treatment for a psychiatric problem, more frequent church attendance, and a high level of academic achievement. While individuals in the community who are at risk for suicide can be targeted for preventive measures, the high prevalence and effect of family problems on likelihood of suicide attempts indicate the need for family - and - community-based approaches. » (p. 8)
