This study investigated the mental health of Portuguese children in Canada. Preliminary work involved a survey of professionals serving the Portuguese community and the translation and assessment of a standardized child behaviour checklist. Forty-five Portuguese children and 45 non Portuguese children referred to a children's mental health centre were compared on demographic and family indicators and their referral source. There were similar proportions of boys and girls in the two groups, similar types of services were requested, and they had similar treatment histories. The Portuguese children were older at the time of referral and were more likely to be referred by educational agencies than the non Portuguese children. Portuguese families appeared to experience different stresses than non Portuguese families. Implications of these findings for the provision of culturally sensitive interventions for Portuguese children and their families are discussed.
