Solutions for fixing non-participation and drop out in health studies
posted on: Dec 2, 2015
Health studies based on individuals provide us with rich sources of information for monitoring the condition of the population and deciding on the need for and value of policies. The reliability of this information depends on how much the people that take part and remain in the study are representative of the population. Dr Linsay Gray of the MRC/CSO Social and Public Health Science Unit has contributed a commentary on approaching the problems of non-participation and drop out. This covers existing and new numerical solutions, including linkage of survey responses to health records where permission has been granted by the individuals, which make the conclusions more trustworthy.
The invited commentary: ‘The importance of post-hoc approaches for overcoming non-response and attrition bias in population-sampled studies’ by Dr Linsay Gray, has been published by the journal Social Psychiatry and Psychiatric Epidemiology and is available here.
