- Exercise addiction is a morbid-compulsive behavioral pattern characterized by a loss of control over exercise and which results in major detrimental consequences in the affected individual’s life. Although the condition is not formally recognized in official psychiatric texts, exercise addiction can lead to clinical impairment of everyday activities just like other more traditional addictions. This has led to the development of many instruments to assess exercise addiction. One of the most widely used instruments is the Exercise Addiction Inventory (EAI) which has been translated into a number of languages and has separate versions of the scale for adults and adolescents (i.e., the EAI-Y for youth). However, there are currently no Persian versions. Therefore, the present study translated the EAI into Persian and assessed its psychometric properties using Rasch analysis among both Iranian adults (n = 745, age range = 19–30 years, 60.53% female) and Iranian adolescents (n = 562, age range = 13–18 years, 62.45% female). An online survey was used to collect data from September to November 2021. Confirmatory factor analyses and the Rasch analyses confirmed the unidimensional structure of the EAIs and good reliability using the Omega coefficient (.71 to.72). Also, separation reliability on item, scale, and person-level was established, along with supported measurement invariance, demonstrating that EAI can discriminate individuals on a high or low level of exercise addiction independent of their age and gender. Overall, the Persian EAI demonstrated sound psychometrics in screening for exercise addiction among Iranian adults and adolescents.

- Health literacy is important for health behavior engagement. Therefore, it is important to have a good instrument assessing health literacy with a theoretical framework. The present study aimed to examine the measurement invariance and differential item functioning (DIF) of a newly developed health literacy instrument; that is, the Health Literacy Instrument for Adults (HELIA). Confirmatory factor analysis (CFA) and Rasch models were used to examine the data collected from a large Iranian sample (N = 9678; 67.3% females; mean age = 36.44 years). All the participants completed the HELIA. CFA was used to examine if the HELIA had a five-factor structure (including reading, access to information, understanding, appraisal, and decision making/behavioral intention factors) and multigroup CFA to examine if the five-factor structure of HELIA was invariant across gender, educational level, accommodation, and age subgroups. Rasch models were used to examine whether each factor of HELIA was unidimensional and DIF contrast in Rasch to examine if the HELIA items were interpreted similarly across the aforementioned subgroups. The CFA results supported the five-factor structure of HELIA, and the Rasch models verified that each HELIA factor is unidimensional. Additionally, multigroup CFA supported the measurement invariance of HELIA across the following subgroups: male vs. female; highly educated vs. poorly educated; city residents vs. suburban residents; and younger age vs. older age. The DIF contrasts in the Rasch models additionally showed that there are no substantial DIF items in the HELIA across aforementioned subgroups. Therefore, the HELIA is a feasible and comprehensive instrument assessing health literacy across different populations in Iran.

- BackgroundHealth literacy and e-health literacy are important factors helping people shape awareness of health behaviours in different aspects, including sleep hygiene behaviours. Good sleep hygiene behaviours promote sleep quality and are beneficial to overall mental wellbeing.ObjectiveWe aimed to examine if sleep hygiene behaviours may mediate the association between health literacy/e-health literacy and mental wellbeing.MethodsAdult Iranian subjects (n = 9775; mean [SD] age = 36.44 [11.97] years; 67.3% females) completed the Health Literacy Instrument for Adults, eHealth Literacy Scale, three items on sleep hygiene behaviour that have been used in prior research and the Short Warwick Edinburgh Mental Wellbeing Scale. Data were then subjected to structural equation modelling (SEM) including 500 bootstrapping resampling to examine whether sleep hygiene is a mediator in the relationship between health literacy/e-health literacy and mental wellbeing.FindingsBoth health literacy and e-health literacy were significantly associated with mental wellbeing (r = .63 for health literacy and .39 for e-health literacy; p < .001) and sleep hygiene behaviours (r = .58 for health literacy and .36 for e-health literacy; p < .001). Sleep hygiene behaviours were significantly associated with mental wellbeing (r = .42; p < .001). Moreover, SEM that incorporated bootstrapping approaches indicated that sleep hygiene behaviours were significant mediators in the association between health literacy/e-health literacy and mental wellbeing.ConclusionsWe conclude that health literacy and e-health literacy are associated with mental health wellbeing in the Iranian population. Additionally, the association could be mediated via sleep hygiene behaviours.Patient or Public ContributionThe study was co-designed with healthcare providers from the vice-Chancellor's Office for Health Affairs of Qazvin University of Medical Sciences as equal partners. Moreover, the women's health volunteers were involved in the design of the study.

- The collected data included socio-demographic information and measurements of health literacy, e-health literacy, men-tal well-being, and sleep hygiene behaviors. The study aimed to provide insights regarding health literacy status and re-lated factors in the general population residing in Qazvin province, Iran. The findings of the study will assist health au-thorities and policy makers in developing and implementing effective interventions, which in turn, improving health lit-eracy in the community. Additionally, the findings can also aid health sector workers, including non-communicable dis-ease researchers, public health experts, health education spe-cialists, epidemiologists, and sociologists, in their work to improve health literacy and overall health outcomes among general population. Therefore, the present study used paper-pencil method with multi-stage cluster sampling to collect data. Trained research associates (n = 25) collected data from9775 people living in Qazvin province between January and April 2022. All the participants completed the study ques-tionnaires using self-reported paper-pencil mode.
