Adolescent Stress Questionnaire: reliability and validity of the Greek version and its description in a sample of high school (lyceum) students.

Adolescence is a crucial phase of human life characterized by enhanced exposure and vulnerability to various stressful stimuli. The Adolescent Stress Questionnaire (ASQ) is a useful measure to evaluate possible sources of stressors affecting the adolescent equilibrium. The present study examines the scientific properties of the Greek version of ASQ to measure perceived stress among 250 Greek adolescents. The confirmatory factor analysis (CFA) results showed a good fit of the original structure of ASQ to the observed data in the Greek sample. A good internal reliability was also confirmed by high Cronbach's alpha values. In line with previous research, girls reported more stress than boys. Overall, the Greek ASQ is a valid and reliable instrument for evaluating adolescent stress.
