Cross-study data guides

Cross-study analysis helps us understand more about group differences, the role of contextual factors and even how societal changes may impact on outcomes for individuals.

Comparable measures across studies can also potentially allow us to combine data and answer research questions with more precision. Such comparisons offer particular research utility in the context of longitudinal studies where we want to evaluate and understand change over the life-course.

As part of our data harmonisation work, CLOSER has produced a series of easily searchable cross-study data guides to help researchers explore and compare the available measures on different research themes both within and across studies.

Explore the guides below and discover measures used to assess cognition, physical activity, and diet in a number of UK longitudinal studies.
