This study examines the influence of family adversity indicators on school-related behavioural problems among Hawaiian and non-Hawaiian adolescents. Questionnaire data from 2787 students were linked to school information, including grade point average (GPA), absences, suspensions and conduct infractions. Logistic regression analyses were performed. The cumulative effect revealed higher increases in the odds ratios for school-related behavioural problems among non-Hawaiians. Surprisingly, there was no cumulative effect of family adversity among Hawaiian adolescents. Given their high rates of adversity and behavioural problems, any family adversity may significantly impact this group. The family environment must be considered in the prevention and intervention of school-related behavioural problems.
