Abstract
Background: The rising prevalence of mental health morbidity among adolescents is worrisome because of the potential for dire consequences. Knowledge of predictive factors that contribute to this situation is considered invaluable. This study aims to determine the effect of personality traits and religiousness/spirituality on adolescent psychopathology.
Methods: The research design was cross-sectional. Big Five Personality Inventory (BFI-44), Ironson-Woods Spirituality/Religiousness Index (IWSRI), and the General Health Questionnaire (GHQ-28) were administered to 412 randomly selected senior secondary school students to evaluate personality traits , spirituality/religiousness, and psychopathology respectively.
Results: Adolescents with psychopathology (GHQ-Positive) had significantly higher neuroticism (p=.000), lower agreeableness (p=.001) and conscientiousness (p=.000); and low levels of religiousness and spirituality scores. High neuroticism (p=.000) and low 'Religious Behaviour' (p=.000) s i g n i f i c a n t l y p r e d i c t e d psychopathology. Religiousness and spirituality were negatively associated with neuroticism, but
positively a s s o c i a t e d w i t h conscientiousness, agreeableness and openness; and no association with extraversion.
Conclusion: The findings of the study provide empirical support for the influence of some personality traits and low religiousness/ spirituality on psychopathology among adolescents in t h i s environment. Further studies in an effort to replicate these findings and to subsequently include them in adolescent mental health promotion programs are advocated.
