Objective: To determine the construct validity and the internal consistency of the Secondary School Stressor Questionnaire (3SQ) among adolescents in secondary school hence in the future it could be used as a valid and reliable instrument to identify their stressors.
Methodology: The 3SQ was developed based on literature review. The face validity of the questionnaire was established through discussion with 30 medical students whereas content validity was established through discussion with experts from related field. It was administered to a total of 100 adolescents in a secondary school. Data was analysed using Statistical Package Social Sciences (SPSS) version 12. Factor analysis was applied to test construct validity whereas reliability analysis (Cronbach's alpha and item total correlation) was applied to test internal consistency of the 3SQ.
Result: A total of 90 (90%) students participated in this study. The total Cronbach's alpha value of the 3SQ was 0.90. The items were loaded into the six pre-determined hypothetical groups.
Conclusion: This study showed that the 3SQ had a good psychometric value. It is a valid and reliable instrument that can be used in the future to identify stressors among secondary school adolescents.
