Brief Summary
The present study aims to develop a new predictive index to predict future depression of adolescents by using factors including individual, interpersonal and environmental. The index can be used to predict likelihood of students who are non-probable depression cases convert into probable depression cases. In addition, the investigators also test the factors of depression remission. It can hence be used in school setting to identify high-risk students, and provide them with secondary interventions that are designed by considering modifiable significant variables identified in this unique, large-scale, longitudinal study.

Outcome Measures
Primary Outcomes (2)
Incidence of probable depression
To examine the incidence of probable depression from non-depression (CESD\<16) at baseline to probable depression (CESD\>=16) at month 12.
12 months
Adolescent Depression Prediction Index (ADPI)
To develop a new prediction index ADPI and test test its performance in predicting incidence of depression.
12 months
Study Arms (1)
Non-cases
Secondary school students (seventh to tenth years of education) without probable depression at baseline interview.
Interventions
The anonymous structured questionnaire will be self-administered by the participating students in the absence of their teachers in class-room settings.
Eligibility Criteria
Out of the 18 districts in Hong Kong, nine randomly selected districts will select randomly two schools and while the rest nine will randomly select one school. Replacements of schools will be made upon refusals. Within the selected schools, all Secondary 1-4 students will be invited to join the study. Students will be asked to fill in baseline questionnaires in the absence of teachers in classroom settings.
You may qualify if:
- Secondary 1 (seventh year of formal education) to Secondary 4 Chinese students, who are studying local mainstream schools in Hong Kong.
- Able to read Chinese and speak either Cantonese or Mandarin.
You may not qualify if:
- Eligible students whose parents refuse to give consent to take part in the study.
