This study identified issues in school – and in life outside school – that caused significant worry for 120 Chinese adolescents (72 males, 48 females) attending a secondary school in Hong Kong. The study explored relationships existing among 3 variables comprising degree of worry, students' general self-efficacy, and their academic achievement. Findings indicated that the students' principal worries centred on school-related matters such as examinations, promotion to higher classes, and getting a job after graduation. Students also worried significantly about the health status of family members, and family finances. Differences in patterns of worry and in self-efficacy beliefs were found between lower- and higher-achieving students. No significant correlations were found among students' degree of worry, general self-efficacy, and achievement. Results are discussed from the perspective of Chinese culture, the Hong Kong education system, and support for students.
