“…Decades of research have shown differences between sleep state perception and objectively measured sleep in a number of clinical sleep populations, most notably insomnia sufferers (80). A variety of patient completed questionnaires have been developed and used to assess perception of sleep in ICU and are covered by recent reviews (4,79). In this review, we focus on the most commonly used tools, and emphasize the validated ones such as the Richard Campbell Sleep Questionnaire (RCSQ), and the tools that were developed more recently.…”

“…We evaluated the strengths and weaknesses of the measures, and their clinical and research usefulness. As an essential step, we assessed their measurement properties based on the criteria described by McDowell (3) and Jeffs and Darbyshire (4). Three aspects were critiqued: construct validity (i.e., whether the tool adequately and appropriately evaluated patient sleep?…”

A Systematic Review of Sleep Measurement in Critically Ill Patients

Background: Clinical trialists and clinicians have used a number of sleep quality measures to determine the outcomes of interventions to improve sleep and ameliorate the neurobehavioral consequences of sleep deprivation in critically ill patients, but findings have not always been consistent. To elucidate the source of these consistencies, an important consideration is responsiveness of existing sleep measures. The purpose of an evaluative measure is to describe a construct of interest in a specific population, and to measure the extent of change in the construct over time. This systematic literature review identified measures of sleep quality in critically ill adults hospitalized in the Intensive Care Unit (ICU), and assessed their measurement properties, strengths and weaknesses, clinical usefulness, and responsiveness. We also recommended modifications, including new technology, that may improve clinical usefulness and responsiveness of the measures in research and practice.

“…Only one study used polysomnography to assess the sleep quality of five patients [21], while other studies used sleep questionnaires. However, sleep questionnaires, such as the Overran-Snyder-Halpern sleep scale, are not adequately validated in critically ill patients after comparison with polysomnography data [10]. To the best of our knowledge, there are no published studies assessing sleep quality of patients in Korean ICUs using the RCSQ, which is currently considered the most validated and reliable tool [10].…”

“…Self-reported subjective assessments offer an alternative approach. Among the subjective tools, the Richards-Campbell Sleep Questionnaire (RCSQ) is the most validated and reliable tool [10]. The RCSQ consists of five questions assessing sleep depth, latency, and fragmentation, as well as time to the resumption of sleep and total sleep quality [11].…”

Reliability of the Korean version of the Richards-Campbell Sleep Questionnaire

Background: Sleep disorders are common in critically ill patients. Unfortunately, sleep assessment is challenging in many intensive care units (ICUs). The Richards-Campbell Sleep Questionnaire (RCSQ) is a simple subjective tool that has been validated and used in many countries. This study aimed to evaluate the reliability of the Korean version of the RCSQ (K-RCSQ). Methods: This prospective, cross-sectional, observational study was conducted in the ICUs of two hospitals. In total, 52 consenting patients answered questionnaires regarding their previous night's sleep (K-RCSQ) and the noise they experienced (range, 0-100). Results: The K-RCSQ showed excellent internal consistency of 0.960 by Cronbach's alpha. The mean total score of the K-RCSQ was 41.9± 28.9 (range, 0-100). The mean perceived ICU noise score was 40.7 ± 28.1 (range, 0-90). There was a significant linear correlation between noise score and average K-RCSQ score (r =-0.37, P < 0.001). Conclusions: The K-RCSQ demonstrated excellent reliability (internal consistency). This simple tool may help assess sleep quality in critically ill patients and improve the quality of ICU care.

“…Nurses use subjective techniques to determine sleep quality, such as a simple tool which allows its assessment. At present, there are a variety of self-assessment scales and questionnaires focused on quantifying and qualifying sleep quality and sleep disorders as well as on factors which have a significant negative effect on the sleep of ICU patients (Hoey et al, 2014;Jeffs and Darbyshire, 2017;Ritmala-Castren et al, 2016). The Richards-Campbell Sleep Questionnaire (RCSQ) is the most commonly used tool for evaluating subjective sleep quality in ICU.…”

Background: Sleep disorders are very frequent among all intensive care unit patients, and disturbed sleep quality has clear and straightforward negative consequences for patients' recovery and level of distress. To promote sleep, nurses must have instruments for observing and evaluating patients' sleep. Objective: The objective of the research was to determine the internal consistency of the Richards-Campbell Sleep Questionnaire (RCSQ) and to compare the selected relationships between the variables (gender, age, type of admission) in the Czech clinical environment of the intensive care unit. Design: Cross-sectional study. Methods: The RCSQ has been translated according to the translation and cultural adaptation manual. The quality of sleep was assessed using the Czech version of the RCSQ. The sample consisted of 105 patients hospitalised in an interdisciplinary intensive care unit. The quality of sleep was measured using a visual analogue scale (0-100). Results: The internal consistency (Cronbach's α) of the Czech version of the RCSQ is 0.89. The average RCSQ score in the sample was 53.2 (SD 20.1). Return to sleep was the lowest rated item at 51 (SD 24.2), while sleep quality was the highest rated item at 55.6 (SD 26.4). There was no statistically significant relationship (p < 0.05) between sleep quality and selected variables: age (F = 0.1; p = 0.736), gender (F = 0; p = 0.929), type of admission (F = 1.8; p = 0.183). Conclusions:The study demonstrates that the Czech version of the RCSQ is rated as a reliable tool and can be used to subjectively assess sleep quality in critically ill patients. The association between sleep quality and selected variables has not been statistically proven and its perception is very individual. Original research article Reliabilita české verze Richards-Campbell Sleep dotazníku SouhrnCíl: Cílem výzkumu bylo určit míru vnitřní konzistence Richards-Campbell Sleep Questionnaire (RCSQ) a porovnat vytipované vztahy mezi proměnnými (pohlaví, věk, druh přijetí) v českém klinickém prostředí jednotky intenzivní péče. Design: průřezová studie. Metodika: RCSQ byl přeložen podle manuálu pro překlad a kulturní adaptaci. Hodnocení kvality spánku bylo zjišťováno pomocí české verze RCSQ. Soubor tvořilo 105 pacientů hospitalizovaných na mezioborové jednotce intenzivní péče. Hodnocení kvality spánku bylo měřeno pomocí vizuální analogové škály (0-100). Výsledky: Průměrné skóre RCSQ v souboru bylo 53.2 (SD 20.1). Nejníže hodnocenou položkou bylo opětovné usínání po probuzení -51 (SD 24.2), naopak nejlépe hodnocenou položkou byla kvalita spánku -55.6 (SD 26.4). Vnitřní konzistence (Cronbachova α) české verze RCSQ je 0.89. Nebyl potvrzen statisticky signifikantní vztah (p < 0.05) mezi kvalitou spánku a vytipovanými proměnnými: věk (F = 0.1, p = 0.736), pohlaví (F = 0, p = 0.929), druh přijetí (F = 1.8, p = 0.183). Závěr: Studie demonstruje, že RCSQ v české verzi je hodnocen jako spolehlivý nástroj a může být používán k subjektivnímu hodnocení kvality spánku u kriticky nemocných. Asociace mezi kvalitou sp...
