In a 5-year longitudinal study, social support was investigated as a predictor of low back pain (LBP) in 46 initially asymptomatic individuals. Distinguishing between colleagues in general and the colleague one feels closest to, the authors analyzed constellations of support from supervisor (which had positive effects) and closest colleague (which had detrimental effects). Configural frequency analysis yielded a type characterized by high support from one's closest colleague and low support from one's supervisor at Time 1 and more LBP and disability at Time 2. Controlling for negative affectivity did not change findings. Results are interpreted in terms of being dependent on that one source of support in an unsupportive environment, which creates feelings of dependence, incompetence, and reciprocity obligations.

The aim of this study was to investigate the nature of tutor and student online communication and collaboration activities in a blended learning course. The hypothesis that these activities are related to student learning performance (exam results) was tested based on the number of messages posted, as well as the nature of these messages (type of content transmitted in terms of course content-related, interpersonal and organizational activities). Descriptive results show that tutors were mainly involved in organizational tasks, whereas students communicated mostly at content-related and interpersonal levels. Student performance was not related to the quantity of tutors' activity, but to the quantity of students' activity. Closer examination of the nature of different activities showed that not only tutors' interpersonal, but also students' own content-related and interpersonal messages had an impact on students' learning performance. This study raises the possibility that the nature of messages is more important than their quantity. It calls into question former research, which has indicated the importance of the amount of activity while mostly neglecting to discriminate between the differences in nature of activities and which has based its findings almost entirely on subjective ratings for both activities and performance. Implications for evaluation of activities and design of personal support are discussed.
