Poor Sleep Quality

Sleep quality is an important clinical construct since it is increasingly common for people to complain about poor sleep quality and its impact on daytime functioning. Moreover, poor sleep quality can be an important symptom of many sleep and medical disorders. However, objective measures of sleep quality, such as polysomnography, are not readily available to most clinicians in their daily routine, and are expensive, time-consuming, and impractical for epidemiological and research studies., Several self-report questionnaires have, however, been developed. The present review aims to address their psychometric properties, construct validity, and factorial structure while presenting, comparing, and discussing the measurement properties of these sleep quality questionnaires. A systematic literature search, from 2008 to 2020, was performed using the electronic databases PubMed and Scopus, with predefined search terms. In total, 49 articles were analyzed from the 5734 articles found. The psychometric properties and factor structure of the following are reported: Pittsburgh Sleep Quality Index (PSQI), Athens Insomnia Scale (AIS), Insomnia Severity Index (ISI), Mini-Sleep Questionnaire (MSQ), Jenkins Sleep Scale (JSS), Leeds Sleep Evaluation Questionnaire (LSEQ), SLEEP-50 Questionnaire, and Epworth Sleepiness Scale (ESS). As the most frequently used subjective measurement of sleep quality, the PSQI reported good internal reliability and validity; however, different factorial structures were found in a variety of samples, casting doubt on the usefulness of total score in detecting poor and good sleepers. The sleep disorder scales (AIS, ISI, MSQ, JSS, LSEQ and SLEEP-50) reported good psychometric properties; nevertheless, AIS and ISI reported a variety of factorial models whereas LSEQ and SLEEP-50 appeared to be less useful for epidemiological and research settings due to the length of the questionnaires and their scoring. The MSQ and JSS seemed to be inexpensive and easy to administer, complete, and score, but further validation studies are needed. Finally, the ESS had good internal consistency and construct validity, while the main challenges were in its factorial structure, known-group difference and estimation of reliable cut-offs. Overall, the self-report questionnaires assessing sleep quality from different perspectives have good psychometric properties, with high internal consistency and test-retest reliability, as well as convergent/divergent validity with sleep, psychological, and socio-demographic variables. However, a clear definition of the factor model underlying the tools is recommended and reliable cut-off values should be indicated in order for clinicians to discriminate poor and good sleepers.

Subjective Happiness Scale

Despite the considerable amount of research evidence on the significant role of subjective happiness on mental health, there is no psychometric study of the Subjective Happiness Scale (SHS) in psychiatric samples. This study was aimed at exploring the psychometric properties of the SHS in a Spanish sample of patients with depressive disorders. Participants were 174 patients with a depressive disorder (70% diagnosed as major depressive disorder) who completed the SHS, the Quick Inventory of Depressive Symptomatology-Self Report (QIDS-SR16), and the EQ-5D Visual Analogue Scale (EQ-5D VAS). Depressive symptoms were also assessed by means of the 17-item Hamilton Depression Rating Scale (HDRS17) and the Clinical Global Impression-Severity (CGI-S) Scale. Dimensionality, internal consistency reliability, construct validity, and responsiveness to change of the SHS were examined. Confirmatory factor analysis replicated the original one-factor structure of the scale. The SHS exhibited good-to-excellent results for internal consistency (α = 0.83) and for convergent [EQ-5D VAS (r = 0.71)] and divergent [QIDS-SR16 (r = −0.72), HDRS17 (r = −0.60) and CGI-S (r = −0.61)] construct validity. The ability of the SHS to differentiate between depression severity levels as well as its responsiveness to clinical change were both highly satisfactory (p < 0.001 in both cases). The SHS retained the soundness of psychometric properties showed in non-clinical samples in a sample of patients with depressive disorders, which supports its use as a reliable and valid outcome measure in the treatment of such disorders.

Positive And Negative Affects

This study examined the mediating roles of both positive and negative affects in the relationship between sleep quality and self-control. A sample of 1,507 Chinese adults (37% men; mean age = 32.5 years) completed self-report questionnaires measuring sleep quality, positive and negative emotions, and self-control. Poor sleep quality was positively correlated with negative affect and negatively correlated with positive affect and self-control. Positive affect was positively correlated with self-control, while negative affect was negatively correlated with self-control. Both positive and negative affects significantly mediated the relationship between sleep quality and self-control. Improving individuals’ sleep qualities may lead to more positive emotions and less negative emotion, and these mood changes may increase resources for self-control. Regulating positive and negative affects may reduce the negative effects of poor sleep quality on self-control.

AbstractObjectives:Reduction in the amount of information (storage capacity) retained in working memory (WM) has been associated with sleep loss. The present study examined whether reduced WM capacity is also related to poor everyday sleep quality and, more importantly, whether the effects of sleep quality could be dissociated from the effects of depressed mood and age on WM.Methods:In two studies, WM was assessed using a short-term recall task, producing behavioral measures for both the amount of retained WM information (capacity) and how precise the retained WM representations were (precision). Self-report measures of sleep quality and depressed mood were obtained using questionnaires.Results:In a sample of college students, Study 1 found that poor sleep quality and depressed mood could independently predict reduced WM capacity, but not WM precision. Study 2 generalized these sleep- and mood-related WM capacity effects to a community sample (aged 21–77 years) and further showed that age was associated with reduced WM precision.Conclusions:Together, these findings demonstrate dissociable effects of three health-related factors (sleep, mood, and age) on WM representations and highlighte the importance of assessing different aspects of WM representations (e.g., capacity and precision) in future neuropsychological research.

This study explored the psychometric properties and construct validity of a new measure of hostility, the Hostile Interpretations Questionnaire (HIQ). The sample consisted of 146 violent offenders incarcerated in a Canadian federal institution. Participants completed a battery of self-report psychometric measures as part of a pre-release psychological assessment. Results indicated that the HIQ had acceptable internal consistency reliability ( r = .86) and demonstrated construct validity with relevant anger/hostility measures. Implications of the findings with respect to theory and practice are considered.

The Relationship

Background Perceived fatigue and fatigability are constructs of multiple sclerosis (MS)-related fatigue. Sleep disturbances lead to poor sleep quality, which has been found to be associated with perceived fatigue in people with MS (PwMS). However, the relationship between fatigability and sleep quality is unknown. Objective To explore the relationship between physical and cognitive fatigability with self-reported and objective measures of sleep quality in PwMS. Methods Fifty-one ambulatory PwMS participated in the study. Physical fatigability was measured by percent-change in meters walked on the six-minute walk test (6MWT) and in force exerted on a repeated maximal hand grip test. Cognitive fatigability was measured using response speed variability on the continuous performance test. Self-report sleep quality was measured using the Pittsburgh Sleep Quality Index, and objective sleep quality was measured using 1 week of actigraphy. Results Components of the Pittsburgh Sleep Quality Index and several actigraph parameters were significantly associated with physical fatigability and cognitive fatigability. However, controlling for depression eliminated the association between the sleep outcomes and cognitive fatigability and attenuated the association between the sleep outcomes and physical fatigability. Conclusion Poor sleep quality is related to fatigability in MS but depression appears to mediate these relationships.

Abstract Objectives This study was performed to identify the relationship between sleep quality and eating habits change after going abroad for international students in South Korea. Methods Using self-report questionnaires, data on general characteristics, health-related variables, sleep pattern and eating habits after going abroad were collected from 225 international students (105 men; 120 women). Results More half of the international students experienced poor sleep quality [poor by PSQI (Pittsburgh Sleep Quality Index) = 52.0%]. Subjects who reported poor sleep quality had significantly higher total score of eating habits after going abroad (P-value &lt; 0.001), the change of environment for dietary consumption (P = value = 0.010) and eating problems after going abroad (P-value = 0.001) than those who reporting good sleep quality. The high BMI (P-value = 0.043) and risk for overweight and obesity [odd ratio (95% CI) = 2.621 (1.301–5.280), P = value = 0.007] showed the subjects with poor sleep quality. Among subjects with worse eating habits after going abroad, the subjects with poor sleep quality increased their risk for overweight and obesity (OR = 3.433, 95% CI = 1.063–11.085, P = value = 0.039) compared to subjects with good sleep quality. However, those findings were not shown the subjects with better eating habits after going abroad. Conclusions The results of this study demonstrated that sleep quality was associated with eating habits after going abroad, and overweight and obesity among international students in South Korea.

Abstract Background Several studies have assessed the Quality of Life (QoL) in Deaf and hard-of-hearing (DHH) children and adolescents. The findings from these studies, however, vary from DHH children reporting lower QoL than their typically hearing (TH) peers to similar QoL and even higher QoL. These differences have been attributed to contextual and individual factors such as degree of access to communication, the participants’ age as well as measurement error. Using written instead of sign language measures has been shown to underestimate mental health symptoms in DHH children and adolescents. It is expected that translating generic QoL measures into sign language will help gain more accurate reports from DHH children and adolescents, thus eliminating one of the sources for the observed differences in research conclusions. Hence, the aim of the current study is to translate the Inventory of Life Quality in Children and Adolescents into Norwegian Sign Language (ILC-NSL) and to evaluate the psychometric properties of the self-report of the ILC-NSL and the written Norwegian version (ILC-NOR) for DHH children and adolescents. The parent report was included for comparison. Associations between child self-report and parent-report are also provided. Methods Fifty-six DHH children completed the ILC-NSL and ILC-NOR in randomized order while their parents completed the parent-report of the ILC-NOR and a questionnaire on hearing- and language-related information. Internal consistency was examined using Dillon-Goldstein’s rho and Cronbach’s alpha, ILC-NSL and ILC-NOR were compared using intraclass correlation coefficients. Construct validity was examined by partial least squares structural equation modeling (PLS-SEM). Results Regarding reliability, the internal consistency was established as acceptable to good, whereas the comparison of the ILC-NSL with the ILC-NOR demonstrated closer correspondence for the adolescent version of the ILC than for the child version. The construct validity, as evaluated by PLS-SEM, resulted in an acceptable fit for the proposed one-factor model for both language versions for adolescents as well as the complete sample. Conclusion The reliability and validity of the ILC-NSL seem promising, especially for the adolescent version, even though the validation was based on a small sample of DHH children and adolescents.

Abstract Introduction Poor sleep quality with short sleep duration (SSD) is a high-risk phenotype that is likely to be associated with primary sleep disorders (obstructive sleep apnea [OSA], periodic limb movements of sleep [PLMS], and restless legs syndrome [RLS]) in older persons. We evaluated the associations among primary sleep disorders and this high-risk phenotype in older persons. Methods Using data on 3,058 men from the Osteoporotic Fractures in Men Sleep Study and 3,127 women from the Study of Osteoporotic Fractures, mean ages 76 and 84 years, respectively, we evaluated cross-sectional associations between primary sleep disorders and the combined outcome of poor sleep quality with actigraphic SSD. In women, OSA and RLS were evaluated by self-report. In men, OSA and PLMS were evaluated by polysomnography and RLS by self-report. Poor sleep quality was defined by Pittsburgh Sleep Quality Index score &gt;5 and SSD by average total sleep time ≤6 hours from wrist actigraphy (averaged over ~5 days). Men and women were evaluated separately. Multivariate logistic regression models also included demographics, self-reported chronic conditions, anxiety, depression, and medication use. Results Poor sleep quality with actigraphic SSD was more prevalent in men (475 [15.6%]) than women (400 [13.1%]). In unadjusted models in men, odds of poor sleep quality with actigraphic SSD were significantly higher with OSA, PLMS, and RLS (ORs [95% Cis] = 1.99 [1.57, 2.52], 2.11 [1.41, 3.18], and 5.58 [2.51, 12.43], respectively). In multivariable models in men, odds of poor sleep quality with actigraphic SSD were significantly higher with OSA (1.59 [1.18, 2.14]) but not with PLMS or RLS. In unadjusted models in women, odds of poor sleep quality with actigraphic SSD were significantly higher with OSA (3.57 [0.40, 31.88]) and RLS (5.60 [3.04, 10.32]), but results were not significant in multivariable models in women. Conclusion Older persons with primary sleep disorders have higher odds of poor sleep quality with actigraphic SSD. However, the predominant mechanisms underlying this high-risk phenotype may be driven more by medical and psychiatric comorbidity than by primary sleep disorders.
