Lisa Calderwood is Principal Investigator of Next Steps and Senior Survey Manager of the Cohort Studies at the Centre for Longitudinal Studies (CLS) in the UK.
Lisa is a survey methodologist and practitioner, with extensive experience and expertise in all aspects of the design, implementation and management of longitudinal surveys. Her research interests cover a wide range of longitudinal survey methods, including non-response and attrition, participant engagement, linking administrative data and survey data and new methods of data collection.
The UK Millennium Cohort Study (MCS) age 14 data collection was the first large-scale longitudinal survey to use a mixed-mode approach involving a smartphone app, web and paper diaries for the collection of time-use data. This seminar will cover the design of the instruments, and present results from pilot studies looking at take-up of different modes and data quality across modes. The age 14 survey also used activity monitors, or accelerometers, to objectively measure physical activity. Such devices are capable of capturing a wide range of movements as well as the differing intensity of activities. MCS used a wrist-worn device.
The presentation will cover the protocols, and examine agreement and compliance rates. It will also cover the use of social media for participant engagement on the MCS.
