Methodological Considerations in a Community-Based Longitudinal Study
Methods : Study participants (N=1117 youth/parent pairs) residing in neighborhoods that were randomly selected using a multistage sampling procedure and 2000 census data. Data were collected annually using in-home, inperson, computer-assisted interviewing methods. Numerous retention methods were used to track and retain participants.
Results : The initial response rate was 61. The retention rate is 97, and the valid interview completion rate is 93 after nearly 4 waves of data collection.
Conclusions : In order for community-based longitudinal studies to overcome barriers to enrollment and retention, particular attention must be given to appropriate planning and available resources.
