| Description | Insomnia is one of the most common health problems patients face today. Nowadays, there are many diagnostic methods aiming to diagnose sleep disorders and insomnia from different aspects, mostly based on sleep characteristics such as sleep duration, time before falling asleep or early morning awakening, etc. Previous studies have shown that the characteristics of insomnia may not be limited to sleep butmay be based on more permanent features of the patient's personality and life history. Researchers have identified significant heterogeneity in the clinical and biomarker characteristics of insomnia leading to subtypes without sufficient validity. The Dutch Insomnia Type Questionnaire aims to identify robust subtypes and thus reduce heterogeneity among insomnia. The aim of our research is to adapt the Insomnia Type Questionnaire into the Czech sociocultural environment and verification of its psychometric characteristics and mapping of subtypes of insomnia. Ourresearch sample consisted of 1051 participants who completed ITQ online.The results of the internal consistency analysis indicated predominantly high internal consistency across scales. The obtained variables were included in the cluster analysis, which showed the presence of five differentinsomnia subtypes. The subtypes were largely equivalent to the subtypes in the original research. |
