Background: There are a number of challenges in developing a reliable and valid instrument on health risk behaviour of adolescents
because adolescents are reluctant to disclose negative health behaviour. This research used the Delphi method, supplemented
by literature review and grounded theory, to understand health risk behaviour and its determinants. Method: Qualitative
questionnaires were sent to experts in round I. In round II, an online questionnaire with major determinants in five point
Likert scale was sent to experts. In round III, a group of experts met, revised and developed consensus on adolescents’ health
risk behaviour and their major determinants. Results: Round I identified 117 major determinants. Altogether, 86 determinants
were selected from round I. In round II, this was reduced to 52 determinants with more than 70 percent consensus. Altogether
12 determinants, which scored more than 50 percent that were supported by literature and grounded theory, were added after
consensus development with experts in round III. Conclusion: Low response rate, identification and selection of experts, experts’
time constraints were major methodological challenges whereas logistic management and time consuming nature of the method
were major non-methodological challenges in the Delphi process. These challenges, however, can be overcome or minimized.
