A short adapted version of the Flow State Scale (FSS-2) for Brazilian-Portuguese and general activities, the FSS-BR-S, was developed and tested with 396 Brazilian participants. The scale, consisting of nine items, showed good internal consistency and a good fit to the data in confirmatory factor analysis. Item quality analysis indicated that its difficulty and differentiating parameters are adequate for estimating overall flow state. The test information curve suggests the short version is useful for estimating flow states. The FSS-BR-S demonstrated sufficient validity for use with Brazilians.
During meditation, forehead temperature decreases more than during rest, while chin temperature rises only during meditation. Among people with meditation experience, differences in left and right forehead and chin temperatures between meditation and rest are significant by the tenth minute. In a non-task state, extraversion correlates negatively with left forehead temperature. After a task, left forehead temperature correlates negatively with mindfulness scores. Infrared thermal imaging offers a practical way to study meditation states, with chin and forehead temperature changes as potential indicators.
Among 16,220 hospital workers in Wuhan, China, surveyed during the COVID-19 pandemic, 13.3% reported suicidal ideation in the past month. Exposure to COVID-19-related traumatic events was significantly associated with insomnia severity, nightmare frequency, and suicidal ideation. After controlling for potential confounders, nightmares—but not insomnia, depression, or anxiety—were independent risk factors for suicidal ideation. Pathway analyses indicated that the relationship between traumatic event exposure and suicidal ideation was fully mediated by nightmares, with a proportion mediated of 66.4%. The authors suggest that nightmare intervention might be considered a component of suicide prevention strategies.
