Behavioral variable Maximum frequency during 6 months
intervals		 Formula for expressing the behavioral variable
1. Attendance to individual sessions 3 individual sessions to be Scheduled % = # attended/3 sessions
2. Attendance to group sessions 18 group sessions scheduled (Months 1–6) % = # attended/18 sessions
3. Number of daily food intake self-monitoring
 entries		 178 days % = # entries/178 days
4. Number of daily physical activity
