Who joins a preventive intervention? How risk status predicts enrollment

The objective of this study was to identify social, psychological, and health-related variables that predict mothers' refusals to join a prevention program for families of children with chronic illnesses. A two-step recruitment process was used with 193 families of children with chronic illnesses. First, families were recruited for a longitudinal research survey. Then, mothers were given the opportunity to randomly receive one of two programs. Mothers who refused the opportunity to participate in either program continued in the research project. Data were collected through structured interviews at baseline and 12 months later: Compared to mothers who agreed to participate in one of the prog rams, those who refused reported more confidence, more support, and less depression and higher functional status and better adjustment in their child. Mothers who agree to participate in a longitudinal research effort but refuse to participate in an intervention program are likely to be functioning well, and may perceive no need for a program designed to prevent mental health problems.
