Notes: Standard deviations in parentheses. Median estimates in brackets. Total number of contacts includes orientations and regular counseling sessions (conducted either via phone or in person). Core sample was N = 158 (TMAC = 70; TMC-plus = 88), but sample sizes vary for client cost categories due to missing data. Where possible, missing values were imputed using sample averages and/or supplementary data. For example, missing hourly wage data was imputed using the federal minimum wage in 2008 ($7.25).
