ABSTRACT

OBJECTIVE: This objective of this study is to examine the association between suicidal behaviour and substance use, depression, aggressiveness and borderline personality traits among adolescents from Sincelejo, a rural city in the north of Colombia. METHODS: This cross sectional study included 352 participants selected by purposive sampling, from a public and a private school located in Sincelejo, Sucre district, in the north of Colombia. Students ages ranged from 12 to 18 years old (mean, 15.09±1.82). The participants completed three screening tools a socio-demographic questionnaire, a screening instrument to collect information related to the frequency of use of some substances, such as tobacco and cannabis, and a self-report inventory to assess various personality and psychopathology domains. A series of t-tests, ANOVA and linear regression analyses were conducted. RESULTS: Physical aggression (t=7.74; p <0.01), cognitive depression (t=5.03; p <0.01), affective depression (t=8.24; p <0.01), affective instability (t=3.46; p <0.01), few social relationships (t=3.36; p <0.01), self-harm (t=3.45; p<.01), cannabis and tranquilizer use (t=2.83; p <0.05; and t=2.37; p <0.05) had a significant independent relationship with suicidal behaviour. Aggression (t=2.59; p <0.05), components of depression (t=9.03; p <0.01) and borderline personality traits (t=4.12; p <0.01) also predicted suicidal behaviour. CONCLUSIONS: More longitudinal studies are needed in this area to identify the causal relations between the factors studied and the suicidal behaviour of young people in Sincelejo.
