Psychometric Properties of the Online Gambling Disorder Questionnaire, Online Gambling Symptom Assessment Scale, and Gambling Urge Scale among Young Adults with the Experience of Online Gambling in Taiwan: A Preliminary Validation Study

Thu, Jul 16, 2026, 05:00 AM

Online gambling and related adverse consequences are increasing among young adults. The present study examined and compared the psychometric properties of the Chinese versions of three online gambling measures: the Online Gambling Disorder Questionnaire (OGD-Q), Online Gambling Symptom Assessment Scale (OGSAS), and Gambling Urge Scale (GUS), among young adult online gamblers. The sample comprised 986 Taiwanese young adults aged 18-30 years who had gambled online in the past year. Internal...
Mediators of the effect of exercise-based cardiac rehabilitation on hospitalisation risk in people with coronary heart disease - the CaReMATCH individual participant data meta-analysis

Thu, Jul 16, 2026, 05:00 AM

Participation in exercise-based cardiac rehabilitation (ExCR) lowers hospitalisation risk in people with coronary heart disease. We investigated whether improvements in health-related quality of life (HRQoL), including physical and mental dimensions, mediated the effect of ExCR on hospitalisation risk in people with coronary heart disease. Individual participant data from five randomised controlled trials were pooled, which randomized participants to ExCR or usual care. All trials had to be...
Associations of habitual coffee intake with testosterone and cardiometabolic markers: the Northern Finland birth cohort 1966 study

Thu, Jul 16, 2026, 05:00 AM

CONCLUSIONS: Higher habitual coffee intake groups showed a leaner body composition, correlated inversely with circulating BCAAs in both sexes, and were independently associated with a sex-specific hormonal profile that may be metabolically relevant, particularly in men. Future longitudinal and intervention studies are needed to establish causality and identify the coffee-derived bioactive compounds involved.
The impact of question order on surveillance of nicotine pouch and smokeless tobacco use among adults in the United States

Thu, Jul 16, 2026, 05:00 AM

CONCLUSION: Nicotine pouch use may be misreported as SLT use on surveys that assess smokeless tobacco first. Consequently, efforts to monitor prevalence of smokeless tobacco use as nicotine pouches gain popularity may be undermined by measurement error.
Feasibility and acceptability of FinCare: A personalized online tool for estimating out-of-pocket costs for cancer treatment

Thu, Jul 16, 2026, 05:00 AM

CONCLUSIONS: FinCare was feasible to implement and acceptable to patients starting a new cancer regimen. Receipt of individualized OOP cost estimates was reported to be useful and did not increase participant anxiety. Study findings, however, are limited by the small sample of patients from a single insurer and a single academic institution. Future studies comprised of larger, more diverse patient populations from multiple insurer groups and centers are warranted to demonstrate the broader...
