English-Canadian high school students (129 boys, 117 girls) participated in a study of the relationship between suicidal ideation and selected personal variables, stress, and social support. Associations were found between suicidal ideation and the variables of gender, self-esteem, locus of control, depression, drug use, stress, perception of health, family status, academic performance, social support, and anomie. Multiple regression analysis identified depression and alcohol use as best individual predictors among these variables. Semi-partial correlation analyses showed that removal of the effect of depression resulted in a loss of initially significant relationships between suicidal ideation and the other variables except for alcohol use, drug use, and health satisfaction.

Abstract English-Canadian (104 boys, 96 girls) and French-Canadian (272 boys, 286 girls) high school students participated in this study of the relationship between suicide ideation and selected variables (age, gender, self-esteem, locus of control, stress, social support, anomy, health, alcohol use, and drug use), with the effect of depression removed. Partial correlation analyses showed that removal of the effect of depression resulted in a loss of or a reduction in the respective relationships between suicide ideation and its correlates. The results suggest that researchers must control for depression if they want to ascertain true correlates of suicidal behavior.

French-Canadian adolescent boys (n = 272) and girls (n = 286) participated in a study of the relationship between suicide ideation and selected familial variables. Results of a multivariate analysis indicate that suicide ideation in adolescent boys and girls is related to a parental child-rearing regime that is characterized by control and a lack of sufficient maternal and paternal social support.

Five hundred fifty-eight French-Canadian adolescents and 150 adults served as subjects in a study that compared correlates of suicide ideation. Results of multivariate analyses indicated that suicide ideation in adolescents is related positively to depression and negative stress and negatively to self-esteem and satisfaction with social support. Adult ideation was found to be related negatively to self-esteem and positively to negative life experiences.

35 men and 35 women participated in a study of the relationship between experienced parental control and level of trait anxiety in early adult life. The correlation for the combined subjects indicated a moderate association between the two variables. Separate analyses for the men and women yielded a significant correlation for the women but not for the men.

38 men and 74 women participated in a study of the relationships among neuroticism, extraversion, locus of control, and assertiveness and aggressiveness, respectively. Aggressiveness was related to extraversion and internal locus of control, while assertiveness was associated with stability as opposed to neuroticism. Sex of subject did not appear to be of importance.

272 French-Canadian adolescent boys and 286 girls took part in a study of the association between parental control in child-rearing and Levensons locus of control dimensions. Analysis showed relations between parental control and the two external dimensions but not with the internal one. Age and gender did not contribute to the various relationships.

French-Canadian adolescent boys (n = 272) and girls (n = 286) participated in a study of the relationship between anomie and selected personal variables. Results of a multivariate regression analysis indicate that adolescents who suffered from anomie tended to be younger boys and girls with low self-esteem who believed that they were subject to chance or fate and who had experienced a number of recent negative life events.

110 French-Canadian adolescents (60 boys, 50 girls) participated in a study of the relationship between parental control in child-rearing and anomie. Correlational analysis indicated that subjects coming from family backgrounds high in parental control generally reported greater feelings of anomie.

Three studies of the relationship between perceived parental control in child-rearing and locus of control were performed in 2 countries. Correlations were nonsignificant. Parental warmth rather than control appears important.
