İNGİLİZCE ÖZET

Objective: The Morningness-Eveningness Questionnaire (MEQ) has
been widely used to determine chronotype. The Munich Chronotype
Questionnaire (MCTQ) was developed as an alternative measurement
tool to the MEQ, focusing on different sleep behaviors on work and
free days. The aim of this study was to adapt the MCTQ to the Turkish
language and to validate the questionnaire on young and healthy adult
members of the Turkish population.
Method: This study was conducted with total of 214 (161 Female,
53 Male) healthy young adult volunteers between the ages of 18-30
(M=20.72, SD=2.33) from Hacettepe University. After adaptation
to the Turkish language to form the MCTQ-TR, the psychometric
properties were compared with the MEQ-TR. The test retest reliability
of the MCTQ-TR was investigated on 25 participants (19 Female, 6
Male), 4 months after the first application.
Results: The test-retest reliability coefficient of the MCTQ-TR was
calculated as r=0.643 (p<0.05). The validity and reliability results
indicated a negative and statistically significant correlation between the
MEQ-TR and MCTQ-TR scores (r=-0.627; p<0.001).
Conclusion: The MCTQ-TR is a valid and reliable measurement tool
that can be used to determine chronotype in healthy Turkish young
adult population.
