Methods: The study was conducted with 377 volunteers who were university students or had more advanced education. The scales for depression, attention deficit and hyperactivity and dissociative experiences were filled in addition to the scale of maladaptive daydreaming.
Results: The analysis shows that the reliability of the scale is high. The factor structure of the Maladaptive Daydreaming Scale was similar to its adaptations to other languages. The scale scores have shown significant correlations with scales of depression, attention-deficit/hyperactivity, and dissociative experiences.
Conclusion: These findings show that reliability, content, and convergent validity of the scale are sufficient. It was concluded that the Maladaptive Daydreaming Scale is suitable for use in the population of Turkey.
