Experimental testing of refusal conversion strategies in a large-scale longitudinal study

Author:   Lisa Calderwood, Ian Plewis, Sosthenes Ketende and Rebecca Taylor

Description:  

CLS Working Paper 2010/9. This paper evaluates the effectiveness of fieldwork strategies to convert refusals using evidence from a randomised experiment implemented on a large-scale longitudinal study in the UK. We show that intensive re-issuing is an effective way of increasing the proportion of refusals converted to a productive interview and hence increasing the sample size and reducing the refusal rate. We also show that refusal conversion may have led to a reduction in non-response bias in the survey estimates for several key variables.

Attitudes towards participating in fMRI studies amongst participants in a birth cohort study

Author:   Matthew Brown and Helen M. Knight

Description:  

CLS Working Paper 2010/8. A sub-sample of National Child Development Study members were invited to participate in a pilot study which sought to investigate the potential of conducting neuropsychological assessments with purposive subsamples of the British Birth Cohort Studies. On completion of the assessments participants completed a short questionnaire which included a number of questions gathering views about participating in research studies involving MRI scanning. This paper summarises the results.

Keeping in touch with mobile families in the UK Millennium Cohort Study

Author:   Lisa Calderwood

Description:  

CLS Working Paper 2010/7. This paper examines what proportion of families who move between waves are successfully located through the study’s tracking procedures, and the effectiveness of techniques designed to pick up address changes prior to the start of fieldwork for a particular wave compared with interviewer tracking in the field. It also looks at some factors associated with success or failure to locate mobile families.

Nonresponse Weight Adjustments Using Multiple Imputation for the UK Millennium Cohort Study

Author:   John W. McDonald and Sosthenes C. Ketende

Description:  

CLS Working Paper 2010/6. This paper discusses nonresponse weight adjustments for sweep 3 of the UK Millennium Cohort Study (MCS). Weight adjustments are available for monotone patterns of nonresponse, where the nonresponse weight is the inverse of the estimated probability of response based on a logistic regression model, which uses data from previous sweeps to predict response at the current sweep.

Understanding Participation: Being part of the 1958 National Child Development Study from birth to age 50

This article presents findings from a study based on qualitative interviews with 170 men and women who have participated in the longitudinal 1958 National Child Development Study for half a century.

Non-response in the 1970 British Cohort Study (BCS70) from birth to 34 years

Author:   Sosthenes Ketende, John McDonald and Shirley Dex

Description:  

CLS Working Paper 2010/4. The main aim of this paper is to analyse the available data from BCS70 about the characteristics of those respondents who are more or less likely to continue to participate, to see if there are lessons to learn that may help future fieldwork practice for longitudinal studies.

The design and content of the ‘Social participation’ study: A qualitative sub-study conducted as part of the age 50 (2008) sweep of the National Child Development Study

Author:   Jane Elliott, Andrew Miles, Sam Parsons and Mike Savage

Description:  

CLS Working Paper 2010/3. This working paper provides an overview of the design of a qualitative sub-study of 170 members of the NCDS8 sweep (2008-9). The central objectives of the sub-study were to investigate the association between individuals’ social mobility experiences and the patterns of social participation, and to provide a resource for other researchers wishing to use this data set.
