Little is known about parents' perceptions of school counselling in Hong Kong. We adopted an explanatory sequential mixed methods design to investigate Chinese and non-Chinese parents' perceptions. In phase one, 287 parents in Hong Kong were surveyed. Results suggested that Chinese parents had a poorer understanding of counsellors' roles, more negative perceptions of counselling, and were less likely to perceive counselling as beneficial than did non-Chinese parents. In phase two, we interviewed 27 parents. Our findings suggested that cultural stigma and school-related factors accounted for the findings of the phase one study. Schools may consider proactive engagement with parents, and establishing communication which is sensitive to cultural norms to promote a better understanding of and willingness to participate in counselling.
