      Sleep deprivation is common in critical patients and it can cause impair consolidation of&#xD;
      memory, cognitive function, metabolic function, immune, neurological and respiratory system&#xD;
      as well as worsen the quality of life after discharge. It has been demonstrated that reducing&#xD;
      sleep disturbance could attenuate the development of delirium in ICU patients. However, sleep&#xD;
      evaluation is only personal perception. There are various methods for sleep monitoring, in&#xD;
      which the most commonly mentioned methods include polysomnography, actigraphy, and the&#xD;
      Richards-Campbell Sleep Questionnaire (RCSQ). The aims of this study is to validate the&#xD;
      accuracy of the Thai-version RCSQ and actigraphy for sleep measurement compared to&#xD;
      polysomnography, which is considered as the gold-standard in Thai critically ill patients&#xD;

    <textblock>
      Sleep is a periodic, reversible state of reduced consciousness, and response to external&#xD;
      stimuli. A total sleep duration of normal human sleep is approximately 7-8 hours per night.&#xD;
      Sleep deprivation is common in critical patients and it can cause impair consolidation of&#xD;
      memory, cognitive function, metabolic function, immune, neurological and respiratory system&#xD;
      as well as worsen the quality of life after discharge. The impact of sleep deprivation in&#xD;
      critically ill patients is gaining attention as it links between sleep loss and delirium. It&#xD;
      has been demonstrated that reducing sleep disturbance could attenuate the development of&#xD;
      delirium in ICU patients. However, sleep evaluation is only personal perception and the&#xD;
      previous study expressed that medical personnel evaluation still showed some error in&#xD;
      approximately 56%. There are various methods for sleep monitoring, in which the most commonly&#xD;
      mentioned methods include polysomnography, actigraphy, and the Richards-Campbell Sleep&#xD;
      Questionnaire (RCSQ). Polysomnography is considered as the gold standard for monitoring the&#xD;
      quantity and quality of sleep. Although, it is difficult to apply in critical care as it&#xD;
      requires expensive setup and maintenance and is prone to patient dislodgment and electrical&#xD;
      interference leading to low quality of signals and missed interpretation.&#xD;
&#xD;
      Nowadays, actigraphy has been used to assess patterns of rest and activity, which can&#xD;
      distinguish sleep from wakefulness. The advantage of actigraphy is easy to use and&#xD;
      non-invasive, can be used by non-specialists, and allows continuous measurement over days to&#xD;
      weeks. On the other hand, its disadvantages are such as neuromuscular weakness and increases&#xD;
      risk of overestimating sleep quantity as periods of inactivity scored as sleep. However, the&#xD;
      technology has been improved recently leading to more accurate sleep measurement. Although it&#xD;
      has been shown that actigraphy is a good alternative sleep measure in non-ICU patients, the&#xD;
      accuracy of actigraphy is unknown in ICU patients.&#xD;
&#xD;
      For subjective tool for evaluating sleep, the Richards-Campbell Sleep Questionnaire (RCSQ) is&#xD;
      one of the most commonly used questionnaires. It contains a simple five-item questionnaire&#xD;
      which are sleep depth, ability to fall asleep, number of awakening, ability to fall asleep&#xD;
      when awake and quality of sleep. The RCSQ shows a good correlation with polysomnography in&#xD;
      sleep efficacy index. The advantages of RCSQ are easy-to-use, inexpensive and providing good&#xD;
      quality of sleep assessment. It has been widely used in the United States and many countries.&#xD;
      Moreover, it has been translated to many languages, such as Spanish, Swedish, German, and&#xD;
      Japanese; and the translated version of RCSQ can be used as an alternative sleep measurement&#xD;
      to polysomnography. Currently, our research group is translating the RCSQ into Thai version&#xD;
      by using standard guidelines on the translation process. In spite of this, The Thai version&#xD;
      of RCSQ (T-RCSQ) has not been validated with polysomnography before.&#xD;
&#xD;
      The aims of our study are to validate the accuracy of the T-RCSQ for sleep measurement&#xD;
      compared to polysomnography, which is considered as the gold-standard and to access the&#xD;
      accuracy of actigraphy for monitoring sleep quality and quantity compared to polysomnography&#xD;
      in Thai critically ill patients admitted to surgical intensive care unit (SICU).&#xD;
