- Given the many technological advances over the past two decades, a small minority of young people are at risk of problematic use or becoming addicted to these technologies (including activities on the internet and smartphones). Many brief psychometric scales have been developed to assess those at risk of problematic use or addiction including the six-item Smartphone Application-Based Addiction Scale [SABAS], the six-item Bergen Social Media Addiction Scale [BSMAS], and the nine-item Internet Gaming Disorder Scale-Short Form [IGDS-SF9]). However, to date, the reproducibility of these three scales has only been examined over a short period of time (e.g., two weeks), and it is unclear whether they are time invariant across a longer period (e.g., three months). Given the emergence of internet and smartphone addiction in Chinese population, the present study translated the three instruments into Chinese and recruited 640 university students (304 from Hong Kong [99 males] and 336 from Taiwan [167 males]) to complete the three scales twice (baseline and three months after baseline). Multigroup confirmatory factor analysis (MGCFA) was applied to examine the time invariance. The intraclass correlation coefficient (ICC) was used to assess the relative reliability, and the percentage of smallest real difference (SRD%) was utilized to explore the absolute reliability for the three scales. MGCFA showed that all three scales were time invariant across three months. ICC demonstrated that all the scales were satisfactory in reproducibility (0.82 to 0.94), and SRD% indicated that all the scales had acceptable measurement noise (23.8 to 29.4). In conclusion, the short, valid, reliable, and easy-to-use Chinese SABAS, BSMAS, and IGDS-SF9 show good properties across periods of three months.

- Internet addiction has been found to be prevalent worldwide, including Asian countries, and related to several negative outcomes and other behavioral addictions. The Bergen Social Media Addiction Scale (BSMAS), Smartphone Application-Based Addiction Scale (SABAS), and nine-item Internet Gaming Disorder Scale-Short Form (IGDS-SF9) have been extensively used to assess internet-related addictions. However, the three aforementioned instruments have rarely been used in Asian countries. The aim of the present study was to investigate whether the BSMAS, SABAS, and IGDS-SF9 were appropriate for use in heterogeneous subsamples from Hong Kong and Taiwan. University students from Hong Kong (n = 306) and Taiwan (n = 336) were recruited via an online survey. Multigroup confirmatory factor analysis (MGCFA) was used to assess measurement invariance of the BSMAS, SABAS, and IGDS-SF9 across the two subcultures. The original unidimensional structures of BSMAS, SABAS and IGDS-SF9 were confirmed through confirmatory factorial analysis in both subcultures. The MGCFA results showed that the unidimensional structures of the BSMAS and IGDS-SF9 were invariant across the two Chinese cultural areas (Hong Kong and Taiwan). However, the measurement invariance of the SABAS was established after some model modifications. In conclusion, the present study found that the Chinese BSMAS, SABAS, and IGDS-SF9 were all adequate instruments to validly assess internet-related addictions among university students. The three brief instruments used for assessing addictions to social media, smartphone applications, and online gaming are valid and psychometrically robust across two Chinese subcultures and can be used by healthcare professionals in these regions.

- Study Objectives: To use theory to design and evaluate an intervention to promote sleep hygiene and health among adolescents.Methods: The Theory of Planned Behavior (TPB) and the Health Action Process Approach (HAPA) were used to develop an intervention, which was then evaluated in a cluster randomized trial. Participants were high school students (N = 2,841, M age = 15.12, SD = 1.50). Adolescents in the intervention group received four face-to-face sessions providing behavior change techniques targeting the theoretical determinants of sleep hygiene. Adolescents in the control group only received educational material at the end of the study. The primary outcome was sleep hygiene measured at 1 and 6 months postintervention. A number of secondary outcomes were also measured, including beliefs about sleep, self-regulatory processes, and outcomes related to health and wellbeing.Results: Sleep hygiene was improved in the intervention group when compared with the control group at both follow-up points (coefficients = 0.16 and 0.19, 95% CIs = 0.12-0.20 and 0.15-0.23 at 1 and 6 months, respectively, for scores on the Adolescent Sleep Hygiene Scale), as were psychosocial and general aspects of health. Mediation analyses suggested that beliefs about sleep hygiene as specified by the TPB, along with self-regulatory processes from HAPA, both mediated the effect of the intervention on outcomes. In turn, the effects of the intervention on sleep hygiene mediated its impact on general health.Conclusions: Healthcare practitioners might consider intervention programs based on the TPB and the HAPA to improve sleep among adolescents.Clinical Trial Registration: Clinicaltrials.gov (NCT02551913) https://clinicaltrials.gov/ct2/show/NCT02551913.

Tidskriftsartikel (refereegranskat)abstract
- Background: This study translated the Adolescent Sleep Hygiene Scale-revised (ASHSr) into Persian and aimed to validate its psychometric properties using classical test theory and Rasch analyses.Methods: Adolescents aged 14–18 (n = 389; 199 males) and their parents in Iran participated in the study. Each adolescent wore a wrist actigraphy device during sleep time and completed the ASHSr, the Depression Anxiety Stress Scale (DASS), the General Health Questionnaire (GHQ), the Pediatric Daytime Sleepiness Scale (PDSS), and the Pittsburgh Sleep Quality Index (PSQI). A parent of each adolescent completed the Sleep Disturbance Scale for Children (SDSC).Results: The construct validity of the ASHSr was supported by both classical test theory (factor loadings from confirmatory factor analysis [CFA] = 0.64 to 0.88; corrected item-total correlations = 0.70 to 0.92; test-retest reliability = 0.72 to 0.90) and Rasch analyses (infit mean square = 0.73 to 1.30; outfit mean square = 0.74 to 1.32). ASHSr had significantly negative associations with DASS subscales (β = −0.15 to −0.42, ps < 0.001) and GHQ (β = −0.663, p < 0.001). Known-group validity was demonstrated by the significant differences between poor and good sleep hygiene based on ASHSr in the actigraphy measure and scores of PDSS, PSQI, and SDSC. The multigroup CFA and differential item functioning in Rasch analyses suggested that all the participants interpreted the ASHSr similarly, regardless of their gender or living in a private room.Conclusions: The Persian ASHSr demonstrated good reliability and validity in assessing sleep hygiene among Iranian adolescents. Healthcare providers may use it to assess the effectiveness of sleep hygiene programs.

- Background/Objective: Given the negative consequences of weight bias, including internalized weight stigma, on health outcomes, two instruments—the Weight Self-Stigma Questionnaire (WSSQ) and Weight Bias Internalization Scale (WBIS)—have been developed. However, their psychometric properties are yet to be tested for Asian pediatric populations.Method: Participants aged 8 to 12 years (N = 287; 153 boys) completed the WSSQ and the WBIS, and they were classified into either a group with overweight or a group without overweight based on self-reported weight and height.Results: Both WSSQ and WBIS had their factor structures supported by confirmatory factor analyses (CFAs). The measurement invariance of two-factor structure was further supported for WSSQ across gender and weight status. The measurement invariance of single-factor structure was supported for WBIS across gender but not across weight status.Conclusions: WSSQ and WBIS were both valid to assess the internalization of weight bias. However, the two instruments demonstrated different properties and should be applied in different situations.

- Background/Objective: Overweight and obese children are likely to encounter negative impact on psychological well-being and quality of life (QoL). Hence, for overweight and obese children, measuring QoL could go beyond simply assessing objective medical parameters and cover their physical health, psychological well-being, and social interaction. Generic (Kid-KINDL and Pediatric Quality of Life Inventory [PedsQL]) and weight-related (Sizing Me Up) measures are two major types of QoL measurement instruments; however, little is known about the differences between them.Method: We recruited 569 3rd to 6th graders from eleven schools in Southern Taiwan. In addition to the three QoL questionnaires, the Child Depression Inventory and Rosenberg Self-Esteem Scale were applied.Results: Depression had significantly negative associations with all three QoL questionnaires. Self-esteem was only associated with Kid-KINDL. Body mass index had a significantly stronger relationship with Sizing Me Up than its relationships with PedsQL and Kid-KINDL. In other words, the items related to body size concerns in Size Me Up significantly contributed to impaired overweight/obese children's QoL.Conclusions: The study further identified the characters and strength of these QoL measures for better suggestions on evaluating physical and psychological issues for overweight/obese children.

- There is an urgent need to measure the impacts of COVID-19 among gay men and other men who have sex with men (MSM). We conducted a cross-sectional survey with a global sample of gay men and other MSM (n = 2732) from April 16, 2020 to May 4, 2020, through a social networking app. We characterized the economic, mental health, HIV prevention and HIV treatment impacts of COVID-19 and the COVID-19 response, and examined whether sub-groups of our study population are disproportionately impacted by COVID-19. Many gay men and other MSM not only reported economic and mental health consequences, but also interruptions to HIV prevention and testing, and HIV care and treatment services. These consequences were significantly greater among people living with HIV, racial/ethnic minorities, immigrants, sex workers, and socio-economically disadvantaged groups. These findings highlight the urgent need to mitigate the negative impacts of COVID-19 among gay men and other MSM.

Sleep hygiene behaviours in Iranian adolescents : An application of the Theory of Planned Behavior

Tidskriftsartikel (refereegranskat)abstract
- Poor sleep quality and inadequate sleep in adolescents are a rising trend globally. The Theory of Planned Behaviour (TPB)-which centres on an individual's attitude toward performing the behaviour, subjective norms and perceived behavioural control-has been applied to examine sleep hygiene behaviours in young adults. We expanded on prior works by using a longitudinal design to examine the effects of TPB factors, together with sleep hygiene knowledge and planning constructs, on sleep hygiene behaviours and on sleep quality and health in a group of Iranian adolescents. A total of 1822 healthy adolescents (mean age = 13.97) from 25 high schools in Qazvin, Iran, completed a self-reported survey at baseline and 6 months later. Structural equation modelling (SEM) was used to delineate the pathway from adolescents' sleep hygiene knowledge, TPB constructs of their behavioural intentions and sleep hygiene behaviours and their sleep quality and self-reported health. The SEM model demonstrated that although behavioural intention, coping planning and action planning predicted the sleep hygiene behaviours positively 6 months later with acceptable model fit [comparative fit index (CFI) = 0.936; Tucker-Lewis index (TLI) = 0.902; root mean square error of approximation (RMSEA) = 0.080; standardized root mean square residual (SRMR) = 0.044], sleep hygiene knowledge did not predict behavioural intentions significantly. Sleep hygiene behaviours were associated with sleep quality and psychiatric wellbeing. Thus, the TPB, combined with coping and action planning, is useful in understanding the sleep hygiene behaviours of adolescents. Health-care providers may want to emphasize TPB constructs and coping and action planning to improve adolescents' sleep hygiene behaviours, rather than rely solely upon increasing adolescents' sleep hygiene knowledge.

Attitudes toward and beliefs about obese persons across Hong Kong and Taiwan : wording effects and measurement invariance
- 2019
-
Ingår i: Health and Quality of Life Outcomes. - : BioMed Central. - 1477-7525. ; 17:1

Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND: The psychosocial consequences of obesity are important but often underrated. The Attitudes Toward Obese Persons (ATOP) and Beliefs About Obese Persons (BAOP) scales used to measure weight-related bias have little psychometric information, especially in East Asian contexts. The objective of this study was to use rigorous statistical methods to demonstrate the psychometric properties of these two instruments in Hong Kong and Taiwanese college students.METHODS: A convenience sample of 707 students was recruited from the universities in Hong Kong and Taiwan. Several competing confirmatory factor analyses (CFAs) were conducted to confirm the factorial structure of the ATOP and BAOP. The best fit models for the ATOP and BAOP were chosen for the examination of the measurement invariance across subcultures. We then compared configurable models with or without loading and/or intercept constrained before correlating the latent constructs between the best models for the ATOP and BAOP.RESULTS: The comparison in multiple CFAs found that the model with one factor and two correlated-wording-method factors outperformed the other models for both the ATOP and BOAP. However, the internal consistency was suboptimal (ATOP: α = .56 to .80; BTOP: α = .57 to .65) and the measurement invariance was somewhat unsupported among the Hong Kong and Taiwan samples. Moreover, after controlling wording effects, the latent construct of the ATOP was moderately associated with that of BAOP (r = .356; p < .001).CONCLUSION: Chinese versions of the ATOP and BAOP can be treated as a unidimensional factor for use in Hong Kong and Taiwan university students. However, further refinements of both instruments may be needed before using them to capture the social attitudes and beliefs toward obesity individuals, which is expected to advance our understanding of weight-related bias in East Asian contexts.
