This study was carried out with 256 adolescents: 56 subjects referred
to adolescent psychiatric outpatient clinics and a control group of 20
9 adolescents from two public high schools in Montreal. Subjects were
divided into two age groups: 12- through 14-year-olds and 15- through
17-year-olds. A questionnaire examining the various characteristics of
the friendship network and the affective nature of friendships was gi
ven to all subjects. The basic hypotheses that guided the present stud
y are confirmed for the older referred subjects. We notice that in com
parison to the control group in high school, the group of referred ado
lescents between the ages of 15 and 17 years possesses a more restrict
ed friendship network. Their relationships are poorer in terms of atta
chment with close friends and are marked more often by conflictual exp
eriences. The severity of diagnosis is comparable between age groups b
ut the older adolescents have an older psychiatric history. A hypothes
is of deterioration of friendship relations was proposed for the refer
red subjects. The results obtained support a model that suggests that
problems in friendship relations and the deterioration of these relati
ons in the course of adolescence constitutes, among other symptoms, th
e expression of more fundamental psychological difficulties that have
driven the referred adolescents to a psychiatric outpatient clinic.
