- Background The psychometric properties of the three-item Minimal Insomnia Symptom Scale (MISS) were evaluated using the classical test theory. Different cut-offs for identifying insomnia were suggested in two age groups (≥6 and ≥7 among adult and elderly people, respectively). The aim of the present study was to test the measurement properties of the MISS using the Rasch measurement model, with special emphasis on differential item functioning by gender and age. Methods Cross-sectional MISS data from adult (age 20–64 years, n = 1075) and elderly (age 65+, n = 548) populations were analysed using the Rasch measurement model. Results Data generally met Rasch model requirements and the scale could separate between two distinct groups of people. Differential item functioning was found by age but not gender. The difference between the adult and elderly samples was lower for the originally recommended ≥6 points cut-off (0.09 logits) than for the ≥7 points cut-off (0.23 logits), but greater at the lower and higher ends of the scale. Conclusions This study provides general support for the measurement properties of the MISS. Caution should be exercised in comparing raw MISS scores between age groups, but applying a ≥6 cut-off appears to allow for valid comparisons between adults and the elderly regarding the presence of insomnia. Nevertheless, additional studies are needed to determine the clinically optimal cut-score for identification of insomnia.

- Background: The high prevalence of physical inactivity in Saudi Arabia is a growing challenge to public health. This study aimed to examine the prevalence of physical activity (PA) and associated factors among female university students. Methods: This cross-sectional study involved 663 randomly selected female university students who completed the Arab Teens Life Style questionnaire. Data included measurements of anthropometric, socioeconomic and environmental factors, as well as self-reported PA. Ordinal regression was used to identify associated factors with low, moderate and high PA levels.Results: The mean age of participants was 20.4 years (SD 1.5). Mean BMI of the students in relation to PA were 23.0, 22.9, 22.1 for high, moderate and low levels of activity, respectively. The analysis revealed significantly higher PA levels among married students, those with high educated mothers, and those who lived far from parks, and lower activity levels among underweight students. Conclusions: This study raises four important determinants for female university students’ PA levels. These factors could be of great importance in the endeavor to prevent the health-threatening increase in physical inactivity patterns and thus non-communicable diseases and obesity where the focus should be on the specific situation and needs of women in Saudi Arabia.

- ObjectivesInsufficient sleep is a public health problem that impacts the mental and physical health of children and adolescents. Complaints of insomnia are particularly pervasive among adolescents. This longitudinal study investigates factors that contribute to teen insomnia symptoms. DesignFive-year prospective follow-up study. SettingSchool-based. ParticipantsA total of 522 children (49.8% girls) aged 9.4 +/- 1.3 years at baseline; 14.4 +/- 0.7 years at follow-up. MeasurementsThe dependent variable of insomnia symptoms at follow-up was assessed with the Minimal Insomnia Symptom Scale-Revised. The independent variables at baseline were the perceived family financial situation, tiredness at school, problems waking up, short sleep duration, sleeping difficulties, having a bedroom Television (TV), and time spent with a TV/computer. Multivariate binary logistic regression analyses were used to examine whether the independent variables at baseline predicted insomnia symptoms at follow-up. ResultsPerceived quite bad/very bad family financial situation (OR 3.1; CI 1.4-6.7) and short sleep duration (<10 h) (OR 2.3; CI 1.0-5.3) among girls at baseline were associated with insomnia symptoms at follow-up. Having problems waking up among boys at baseline was associated with insomnia symptoms at follow-up (OR 4.9; CI 1.6-14.4). ConclusionShort sleep duration, problems waking up, and perceived bad family financial situation during childhood were linked with adolescent insomnia symptoms. The sex-based differences in these associations warrant further investigation to effectively mitigate adolescent insomnia.

- Background Sleep deprivation among adolescents is a major public health issue. Although previous studies have described their sleep habits and the consequences thereof, the voices of adolescents themselves are rarely heard. The aim of this study was to investigate adolescents' experiences regarding what they perceived as facilitators and barriers for a good night's sleep. Methods A qualitative focus group study with Swedish adolescents (n = 45) aged 16-18 years was performed with seven focus groups and analyzed using qualitative content analysis. Results Three categories were identified in the analysis regarding facilitators and barriers for achieving a good night's sleep: (1) Striving for a sense of well-being, (2) Tiring yourself out, and (3) Regulating electronic media availability. The adolescents thought that sleep was important in order to be able to cope with everyday life and to allow physical recovery. Overall, the adolescents were knowledgeable regarding commonly recommended strategies for improving sleep, but they had trouble finding a balance between sleep and other activities. Electronic media was used to obtain a sense of belonging and to communicate with others, which in itself was described as important for the adolescents' well-being. However, communicating with friends and family during the night conflicted with achieving a good night's sleep. Parental behaviors (late work habits, internet rules) were also perceived as important for adolescents' sleep habits. Conclusions An understanding of the dilemma of finding a balance between sleep and other activities may aid future sleep-promoting interventions for adolescents, incorporating the impact from social factors' on the adolescents' sleep.

- Purpose: Insomnia affects up to one in four adolescents and has been shown to have a negative impact on their mental and physical health. This study aimed to investigate the association between insomnia, academic performance, self-reported health, physical activity, school start time, and substance use among adolescents. Methods: A survey with a cross-sectional design was completed by adolescents (15-17 years old; n = 1504) in southern Sweden. The Minimal Insomnia Symptoms Scale (MISS) was used to operationalize insomnia. A multiple logistic regression analysis was used to analyze the relationship between insomnia and self-reported health, failed school courses, substance use, school start time, family financial situation, screen time, and gender. Results: Insomnia (MISS >= 6) was associated with poor self-reported health (OR: 4.35), failed school courses (OR: 1.47), and use of alcohol and/or cigarettes (OR: 1.43). When the combined effect of self-reported health and physical activity were investigated, a combination of low physical activity (<= 1 time/week) and poor self-reported health was strongly associated with insomnia (OR: 18.87). Conclusions: Insomnia was associated with other problems that in themselves are risk factors for poor health. This highlights the need for a holistic health-promoting approach to prevent insomnia, such as efforts to promote physical activity, school success, and the reduction of alcohol/cigarette use.

- CONTEXT: Previous studies have supported the psychometric properties of the 22-Item Zarit Burden Interview (ZBI-22) scale among family caregivers of people with various disorders, including Parkinson's disease (PD). However, its short forms have not been psychometrically tested among PD family caregivers, and available psychometric analyses have not accounted for the ordinal nature of item-level data.OBJECTIVES: To assess the psychometric properties of the ZBI-22 and its short forms among family caregivers of people with PD, while taking account for the ordinal nature of data.METHODS: Cross-sectional postal survey ZBI-22 data from 66 family caregiver members (59% women; mean age 69.6 years) of a local Swedish PD society branch were analyzed according to classical test theory methods based on polychoric/polyserial correlations.RESULTS: Missing item responses were ≤ 5%. Corrected item-total correlations were ≥ 0.42 and floor/ceiling effects were <20%, besides for the briefest (4- and 1-item) short forms (20% and 40% floor effects, respectively). Reliability was good for all scales (ordinal alpha 0.89-0.95). External construct validity was in general accordance with a priori expectations. Short forms demonstrated good criterion-related validity (rs 0.87-0.99) and discriminative ability (area under the curve, 0.91-0.98) relative to the full ZBI-22.CONCLUSION: This study provides support for the reliability and validity of the ZBI-22 and its various short forms for use among PD family caregivers. In studies where caregiver burden is a central outcome, either ZBI-22 or ZBI-12 is suggested for use; other short forms can be used when caregiver burden is of less central focus or for clinical screening.

Beware of the origin of numbers : Standard scoring of the SF-12 and SF-36 summary measures distorts measurement and score interpretations
- 2017

- The 12-item Short Form Health Survey (SF-12) is a generic health rating scale developed to reproduce the Physical and Mental Component Summary scores (PCS and MCS, respectively) of a longer survey, the SF-36. The standard PCS/MCS scoring algorithm has been criticized because its expected dimensionality often lacks empirical support, scoring is based on the assumption that physical and mental health are uncorrelated, and because scores on physical health items influence MCS scores, and vice versa. In this paper, we review the standard PCS/MCS scoring algorithm for the SF-12 and consider alternative scoring procedures: the RAND-12 Health Status Inventory (HSI) and raw sum scores. We corroborate that the SF-12 reproduces SF-36 scores but also inherits its problems. In simulations, good physical health scores reduce mental health scores, and vice versa. This may explain results of clinical studies in which, for example, poor physical health scores result in good MCS scores despite compromised mental health. When applied to empirical data from people with Parkinson's disease (PD) and stroke, standard SF-12 scores suggest a weak correlation between physical and mental health (r(s). 16), whereas RAND-12 HSI and raw sum scores show a much stronger correlation (r(s). 67-.68). Furthermore, standard PCS scores yield a different statistical conclusion regarding the association between physical health and age than do RAND-12 HSI and raw sum scores. We recommend that the standard SF-12 scoring algorithm be abandoned in favor of alternatives that provide more valid representations of physical and mental health, of which raw sum scores appear the simplest.
