The Adolescent Insomnia Questionnaire: the Turkish validity and reliability study

Area of Science:

• Adolescent psychology
• Sleep medicine
• Psychometric evaluation

Background:

• Adolescent sleep disturbances, particularly insomnia, are a growing concern.
• Validated assessment tools are crucial for accurate diagnosis and intervention.
• The Adolescent Insomnia Questionnaire (AIQ) is a widely used measure, but its Turkish adaptation required evaluation.

Purpose of the Study:

• To establish the Turkish validity and reliability of the Adolescent Insomnia Questionnaire (AIQ).
• To provide a culturally adapted and psychometrically sound instrument for assessing insomnia in Turkish adolescents.
• To facilitate research and clinical practice related to adolescent sleep in Turkey.

Main Methods:

• The study involved 265 adolescents, administering the AIQ and Cleveland Adolescent Sleepiness Questionnaire.
• Exploratory and confirmatory factor analyses were employed to assess construct validity.
• Reliability was determined through test-retest correlation, Cronbach's alpha, and inter-item correlations.

Main Results:

• The AIQ demonstrated strong internal consistency (Cronbach's α > 0.80) and good test-retest reliability (r=0.675).
• Confirmatory factor analysis supported the AIQ's factor structure with excellent fit indices.
• Significant positive correlations were observed between AIQ and Cleveland Adolescent Sleepiness Questionnaire scores, indicating convergent validity.

Conclusions:

• The Turkish version of the AIQ is a valid and reliable instrument for measuring insomnia in adolescents aged 11-18.
• The AIQ is a practical, self-administered tool suitable for the Turkish adolescent population.
• This study provides the first Turkish validation of the AIQ, supporting its use in clinical and research settings.
