Purpose:
The purpose of this study was to determine the validity and reliability of the Adolescent Asthma Self-Efficacy Questionnaire for the Turkish population.
Design And Method:
This study involved 198 adolescents aged 12-18 who had been diagnosed with asthma. Data were collected using the Sociodemographic Information Questionnaire and the Turkish version of the Adolescent Asthma Self-Efficacy Questionnaire. The validity of the scale was evaluated using the content validity index, explanatory and confirmatory factor analyses, Cronbach's alpha reliability score, split-half method, item-total score correlation, and test-retest.
Results:
The Turkish version of the Adolescent Asthma Self-Efficacy Questionnaire has a total explained variance of 63%. Factor loadings were found to be higher than 0.40 in both explanatory and confirmatory factor analyses. The test-retest reliability coefficient is 0.91, and the total Cronbach's alpha value of the scale is 0.93, with all subscales having a Cronbach's alpha value >0.84. The model fit indices of the scale were found to be at an acceptable level.
Conclusion:
The Adolescent Asthma Self-Efficacy Questionnaire is a valid and reliable measurement tool for the Turkish population.
Practice Implications:
The AASEQ can be a useful tool for healthcare professionals in the assessment of self-efficacy in adolescents who have had a diagnosis of asthma.
