Psychometric Properties of the Persian Pittsburgh Sleep Quality Index for Adolescents

Both cross-sectional and longitudinal studies show that poor sleep is a health concern related to further psychological and physiological issues during adolescence. To assess subjective sleep quality and sleep patterns among adults, the Pittsburgh Sleep Quality Index (PSQI) is a well and internationally established tool. Here, we established the psychometric properties of the Persian version of the PSQI for adolescents.; A total of 1477 adolescents (mean age: 15.47 years; 53.2% females) took part in the study. They completed a booklet on sociodemographic information, the Persian version of the PSQI for adolescents, and the Adolescent Sleep Hygiene Scale (ASHS). We relied on classical test reliability approaches of exploratory and confirmatory factor analyses.; Classical exploratory factor analysis yielded the seven-factor solution, with concurrent confirmation and overlap with the dimensions of the ASHS, although correlation coefficients were small to medium. A further factor analysis yielded a four-factor solution, explaining 72% of the variance of the PSQI. Further, three out of these four factors predicted the ASHS overall score.; The Persian version of the PSQI for adolescents showed satisfactory psychometric properties. It follows that the Persian PSQI is a suitable tool to assess sleep quality and sleep patterns among adolescents

The role of death anxiety as a mediator in the relationship between personality types and psychological well-being in coronavirus disease-2019 patients

BACKGROUND: Given the widespread presence of the coronavirus disease-2019 (COVID-19) virus, it is critical to explore the psychological consequences of this disease on people at all levels of society. The purpose of this study was to look into the role of death anxiety as a mediator in the relationship between personality types and psychological well-being in people with COVID-19 disease. MATERIALS AND METHODS: In this study, the research method is correlational in terms of descriptive data collection method. The statistical population consisted of all people who had experienced COVID-19 in Kermanshah, Iran 2020–2021, 220 of whom were chosen by the available sample method. The Ryff Psychological Well-Being Questionnaire (PWBQ), the personality types of John and Srivastava's short five-factor list (BFI-SV), and the Collett-Lester Anxiety Death Scale were among the research instruments employed (CL-FODS). The suggested model was evaluated using the structural equation modeling strategy and the Amos software. RESULTS: The findings demonstrated that extraversion, adaptation, and conscientious personality types have a positive and significant relationship with psychological well-being while neuroticism has a negative and significant relationship with psychological well-being, and openness to experience indirectly improves psychological well-being by reducing death anxiety. CONCLUSION: Death anxiety appears to play a mediating role in the relationship between personality types and psychological well-being in people with COVID-19, according to the findings of this study. As a result, the proposed model fits well and can be used as an important step in identifying factors that affect people with COVID-19's psychological well-being

Sleep hygiene and sleep quality in Iranian adolescents during the COVID-19 pandemic

Abstract Objectives Sleep is one of the issues that attracted the attention of researchers during the COVID-19 pandemic. Researchers focused their studies on the prevalence of sleep disorders, sleep quality, and sleep duration. Sleep hygiene is a set of guidelines that play an important role in the sleep quality, the present study sought to evaluate the amount of sleep hygiene and sleep quality in Iranian adolescents and their relationship during the COVID-19 pandemic. Methods The present study was conducted using a cross-sectional design. The research population consisted of all adolescents living in Kermanshah (western Iran) in 2021. The participants were a sample of 610 adolescents. They completed the Pittsburgh Sleep Quality Inventory and Adolescent Sleep Hygiene Scale. Results The mean sleep quality score for the participants was 7.14 ± 2.47, indicating the high frequency of sleep problems affecting the participants. There were significant correlations between all components of sleep hygiene and sleep quality. There was also a significant correlation (r = − 0.46 between sleep hygiene and sleep quality (p < 0.001). No significant difference was observed in sleep hygiene and sleep quality between the male and female adolescents. The results showed that sleep hygiene subscales can predict sleep quality (R = 0.53, F = 39.20, p < .01). Conclusions The data in this study confirmed the poor observance of sleep hygiene in adolescents during the COVID-19 pandemic and reported frequent sleep problems among the participants. The results also indicated a moderate relationship between sleep hygiene and sleep quality in adolescents. Thus, sleep hygiene components can be related to sleep quality

Associations of Sleep Problems and Self-regulation With Interpersonal Aggression Among Healthcare Workers

Background and Purpose: Sleep problems and aggression are common among healthcare workers due to shift work and constant interaction with patients and their relatives. The present study examined the associations between sleep problems, self-regulation, and interpersonal aggression among healthcare workers. Materials and Methods: In this cross-sectional study, 400 healthcare workers were selected from four state-run hospitals in Kermanshah City, Iran, using a multi-stage random sampling between March 2021 and March 2022. The sample size was selected using the N>50+8m standard formula. The participants completed several standard scales, including the Pittsburgh sleep quality index, the Berlin questionnaire, the insomnia severity index, the self-regulation questionnaire, and the Buss-Perry aggression questionnaire. The obtained data were analyzed using the Pearson correlation, hierarchical multiple regression techniques, and standardized z scores. Results: The Mean±SD age of the participants was 32.5±8.8 years and 70% were female. All sleep problems, including poor sleep quality, sleep apnea, and insomnia severity, are significantly related to the total score of interpersonal aggression and all its subfactors (P<0.001). The results showed that adding self-regulation to sleep problems to predict aggression greatly reduces the effect of sleep problems, especially the insomnia severity (P<0.001). Conclusion: The results showed that self-regulation is not only a protective factor for aggression but also indirectly protects against aggression by controlling the severity of insomnia. Because both sleep problems and self-dysregulation are modifiable risk factors for interpersonal aggression, psychological interventions can target these risk factors

The relationship between parents’ sleep quality and sleep hygiene and preschool children’ sleep habits

Objective: The relationship between parents’ sleep quality and sleep hygiene and preschool children’s sleep habits was examined. Material and Methods: The study population consisted of the parents of all preschool children at daycare centers located in Kermanshah Province. Through cluster sampling, 153 parents from 26 daycare centers were selected. In order to assess the quality of sleep and sleep health of parents, Pittsburg sleep quality index (PSQI) and sleep hygiene index (SHI) were used. As to the status of childrens sleep habits (CSH), the parents also completed child sleep habit questionnaire (CSHQ). Data analysis was performed in SPSS version 25. The non-parametric tests like U Mann-Whitney test, Kruskal-Wallis’s test, Spearman’s rho, and regression test were used. Results: The mean score of CSHQ from the parents’ viewpoint was 56.34±7.96, which meant a relatively improper sleep habits in the children. The CSH was significantly and directly related to parents’ sleep quality and all of its subscales except two sub-scales (SSQ and HSE). In addition, CSH was directly and significantly related to the parents’ sleep hygiene and its three subscales. The results of multiple linear regression showed that the impact coeffcient of parents’ sleep quality (B=1.02), given the t-value, predicted changes in CSH with 0.99 confidence. Conclusion: In general, the results showed that CSH was in a relatively bad state, while it had a direct relationship with parents’ sleep quality and hygiene. To improve CSH, it is possible to improve parents’ sleep quality through implementing proper programs and motivating parents to observe sleep hygiene

Validation of the Persian version of the Pittsburgh Sleep Quality Index in elderly population

Objective: The purpose of this study is to determine the validity and reliability of the Persian version of the Pittsburgh Sleep Quality Index in the elderly population. Material and Methods: A methodological study was conducted as a confirmatory factor analysis. Totally, 598 elderly people were selected through cluster sampling. In addition to analyzing the three-factor structure of PSQI, internal consistency reliability, structural validity, and its concurrent validity were examined. The structural credibility of PSQI was examined using other similar tools such as Sleep Health, Epworth Sleepiness, Insomnia Severity, Global Sleep Assessment, and Berlin indices. Finally, the concurrent criterion validity of PSQI was evaluated through multivariable regression analysis and all statistical analyzes were performed using SPSS and AMOS software. Results: The reliability of the test according to Cronbach’s alpha was 0.81. Confirmatory factor analysis indicators supported goodness of fit of the structural equation model. The confirmatory factor analysis showed that the ratio of χ2 / DF was 2.66 for the three-factor structure of PSQI and the goodness of fit indices of model were acceptable for this structural model (RMSEA=0.053, CFI=0.98, TLI=0.96, NFI=0.97, GFI=0.99). In addition, the internal consistency of the PSQI was 0.81 and the scales correlation score ranged from 0.48 to 0.71. Conclusion: The results indicated that Persian version of Pittsburgh Sleep Quality Index had the required validity and reliability for the elderly population of Iran and it can be used as a useful tool by other studies

Validation of the Farsi version of the revised Adolescent Sleep Hygiene Scale (ASHSr): a cross-sectional study

Abstract Background Restoring sleep is associated with a broad variety of favorable cognitive, emotional, social and behavioral benefits during the day. This holds particularly true for adolescents, as maturational, social, cognitive, emotional and behavioral changes might unfavorably impact on adolescents’ sleep. Among adolescents, poor sleep hygiene practices are a potentially modifiable risk factor that can be addressed via appropriate interventions. Accordingly, having reliable and valid self-report measures to assess sleep hygiene practices is essential to gauge individual responses to behavioral interventions and evaluate sleep hygiene recommendations. The aim of the present study therefore was to translate and to test the psychometric properties (internal consistency, test-retest reliability, factorial and concurrent validity) of the Farsi/Persian version of the revised version of the Adolescent Sleep Hygiene Scale (ASHSr). Method A total of 1013 adolescents (mean age: M = 15.4 years; SD = 1.2; range: 12–19 years; 42.9% females) completed the ASHSr and the Pittsburgh Sleep Quality Index (PSQI) in their classroom during an official school lesson. Further, 20% completed the ASHSr 6 weeks later to evaluate the test-retest reliability. Cronbach’s alpha coefficients were calculated to examine internal consistency, confirmatory factor analysis (CFA) was used to test factorial validity, whereas concurrent validity and test-retest reliability were examined via correlation analyses. Results A first-order confirmatory factor analysis (CFA) corroborated the six-factor structure of the ASHSr, including a physiological, behavioral arousal, cognitive/emotional, daytime sleep, sleep environment, and sleep stability factor. A second-order CFA showed that a higher-order sleep hygiene construct explained sufficient variance in each factor. Cronbach’s alpha values ranged between .71 and .75, correlations for test-retest reliability between .82 and .87. Significant correlations were found between most ASHSr scales and the PSQI indices. However, the magnitude of these correlations was weak. Conclusions The Farsi/Persian version of the Adolescent Sleep Hygiene Scale can be used as a reliable and valid tool for evaluation of sleep hygiene practices among Farsi/Persian-speaking adolescents

Among adolescents, addiction susceptibility and sleep-related dysfunction have a common cognitive-emotional base and predict poor sleep quantity

Background: Among adolescents, the self-pacing of sleep and experimentation with psychotropic substances increases. Poor sleep and susceptibility to addiction (SA) may therefore share common cognitive-emotional processes. The aim of the present study was to investigate the shared cognitive-emotional basis of SA and sleep-related dysfunction, and to explore their predictive value for sleep patterns. Methods: A total of 300 adolescents (mean age:15.57 years;50% females) took part in this questionnaire-based study. Participants completed a booklet covering sociodemographic, sleep-related (Sleep Hygiene Index: SHI; Pittsburgh Sleep Quality Index: PSQI) and SA-related variables. Results: Greater sleep-related dysfunction based on the SHI was strongly associated with higher SA scores. Parents’ educational level was negatively associated with SHI and SA scores. An exploratory factor analysis of SHI and SA items yielded three distinct factors: (i) risky behavior and irregular sleep-wake schedules, (ii) poor sleep environment and hygiene, and (iii) psychological arousal and distress. All three factors independently contributed to the prediction of poor sleep quality and quantity. Conclusions: Adolescents reporting dysfunctional cognitive-emotional processes are at increased risk of reporting poor sleep patterns. Additionally, poor sleep and SA were related to parents’ education, suggesting that both parents and their children might benefit from sleep hygiene counseling
