ABSTRACT

Objective

To identify the independent psychosocial and risk behavior correlates of suicidal ideation and attempts.

Method

The relationships between suicidal ideation or attempts and family environment, subject characteristics, and various risk behaviors were examined among 1,285 randomly selected children and adolescents, aged 9 through 17 years, of whom 42 (3.3%) had attempted suicide and 67 (5.2%) had expressed suicidal ideation only. The youths and their parents were enumerated and interviewed between December 1991 and July 1992 as part of the NIMH Methods for the Epidemiology of Child and Adolescent Mental Disorders (MECA) Study.

Results

Compared with subjects with suicidal ideation only, attempters were significantly more likely to have experienced stressful life events, to have become sexually active, to have smoked more than one cigarette daily, and to have a history of ever having smoked marijuana. After adjusting for sociodemographic characteristics, a statistically significant association was found between suicidal ideation or attempt and stressful life events, poor family environment, parental psychiatric history, low parental monitoring, low instrumental and social competence, sexual activity, marijuana use, recent drunkenness, current smoking, and physical fighting. Even after further adjusting for the presence of a mood, anxiety, or disruptive disorder, a significant association persisted between suicidal ideation or attempts and poor family environment, low parental monitoring, low youth instrumental competence, sexual activity, recent drunkenness, current smoking, and physical fighting.

Conclusion

Low parental monitoring and risk behaviors (such as smoking, physical fighting, alcohol intoxication, and sexual activity) are independently associated with increased risk of suicidal ideation and attempts, even after adjusting for the presence of psychiatric disorder and sociodemographic variables.

METHOD

The methods of this study have been described in detail in the report of the MECA study (Lahey et al., 1996), and the diagnostic and demographic features of the subsample of suicidal youths have been described in Gould et al. (1998).

RESULTS

Of the total sample, 67 subjects (5.2%) reported suicidal ideation within the past 6 months but no lifetime history of suicide attempt; an additional 42 (3.3%) subjects reported a lifetime history of suicide attempt (Gould et al., 1998). The remaining 1,176 subjects denied having had either suicidal ideation in the past 6 months or any lifetime history of suicide attempt.

Subjects with a lifetime history of suicide attempts were compared on the principal variables with subjects reporting

DISCUSSION

Adverse family circumstances, such as caretaker's low satisfaction with the family environment, low parental monitoring, and parental history of psychiatric disorder, were significantly associated with suicidal ideation and behavior, even after we controlled for age, gender, and demographic factors. High levels of negative life events were also associated with increased risk of suicidal ideation or attempts. The effects of potential social risk factors found to be associated in other studies
