The facial affective scale as a predictor for pain unpleasantness when children undergo immunizations.

Needle fear is a common problem in children undergoing immunization. To ensure that the individual child's needs are met during a painful procedure it would be beneficial to be able to predict whether there is a need for extra support. The self-reporting instrument facial affective scale (FAS) could have potential for this purpose. The aim of this study was to evaluate whether the FAS can predict pain unpleasantness in girls undergoing immunization. Girls, aged 11-12 years, reported their expected pain unpleasantness on the FAS at least two weeks before and then experienced pain unpleasantness immediately before each vaccination. The experienced pain unpleasantness during the vaccination was also reported immediately after each immunization. The level of anxiety was similarly assessed during each vaccination and supplemented with stress measures in relation to the procedure in order to assess and evaluate concurrent validity. The results show that the FAS is valid to predict pain unpleasantness in 11-12-year-old girls who undergo immunizations and that it has the potential to be a feasible instrument to identify children who are in need of extra support to cope with immunization. In conclusion, the FAS measurement can facilitate caring interventions.

Forskning med juridiska förvecklingar : Om tolkningsflexibilitet i kontroversen om mässlingsvaccination och autism

Medical research with jurisdictional consequences: interpretative flexibility in the controversy over MMR vaccination and autism Based on the empirical case of the controversy of MMR vaccination and autism around the turn of the millennium, this paper argues for the analytical importance of the concept of “interpretative flexibility”. As shown, this concept is useful not only for the small subfield of sociology of scientific knowledge (SSK) but also for the broader social sciences. First we analyse, by reference to interpretative flexibility, the initial dispute within medical research concerning evidence for and against a possible link between the measles component of the MMR vaccine and autism. In a second step we move beyond this traditional application of the concept, showing how the interpretative flexibility of the research results remains in society although consensus has been reached in the medical community. This further step is exemplified by two legal events, in Sweden and the US respectively. In both these cases the difficulties in providing uncontested evidence affected institutions and practices at great distance and with different outcomes. Our findings suggest the importance of not only applying the concept of interpretative flexibility to classical scientific laboratory disputes, but also connecting it to its societal manifestations.
