Background: As the low back pain (LBP) population is highly heterogeneous, researchers have attempted to classify LBP based on symptom duration. Differences in lumbar muscle structure, pain processing, and clinical symptomatology have been found between recurrent LBP (RLBP) and chronic LBP (CLBP), and could possibly be explained by the grade of chronicity. However, recent findings suggest that also within the CLBP population, distinct ...

Spanish intralinguistic variation entails differences in the ways of perceiving the world, analyzing events and behaving, which must be taken into account when designing and adapting questionnaires. The IA-PLAT (Primary Care Assessment Tools for lberomerica) harmonization process differs from the cross-cultural adaptation scenarios described in the scientific literature, ...

Background: Poor to moderate validity of self-reported physical activity instruments is commonly observed in young people in low- and middle-income countries. However, the reasons for such low validity have not been examined in detail. We tested the validity of a self-administered daily physical activity record in adolescents and assessed if personal characteristics or the convenience level of reporting physical activity modified the validity ...

As a newly emerged eco-friendly public transport mode, the community bus is widely regarded as one of the effective means of solving the “last mile” problem for urban rail service. To inform policies that promote the development of the community bus, understanding the determinants that influence the choice of the community bus is essential. Taking Dalian, China as a case, this study conducts a questionnaire survey combining stated preference and ...

This article draws from grid-group cultural theory (GGCT) to develop a survey instrument that allows to take an “adequate snapshot” of the culture of an organization. It specifies GGCT’s typology into 15 dimensions, situated in the twodimensional space defined by the cross-tabulation of the grid and group axes. Those 15 dimensions are operationalized in a questionnaire that is used in two consecutive studies: one in 64 local police forces in ...

OBJECTIVES: To compare the knowledge about HIV between people with schizophrenia and the general population. METHODS: The knowledge about HIV was assessed with a questionnaire used in the ...
