aFirst 5 began distributing the Kit for New Parents statewide in November, 2001.
bBecause the original comparison group was recruited 6 months after the intervention group was, there was concern that mothers in the comparison group might receive the kit during the 6-month wait for their 14-month interview, thereby contaminating the findings. Therefore, a new comparison sample of mothers who could be interviewed during the same time period that the intervention mothers had their 14-month follow-up interviews was recruited through a snowball sampling method.
