Notes. All monetary values are reported in 2008 dollars and rounded to nearest $10. Individual sources are reported only when n > 5, but all sources are included in the total income. During-treatment income is income reported during the 3-month treatment period. Pretreatment income is a 3-month estimate of income calculated from self-reported past year income at study intake. Earned income includes under the table jobs, seasonal positions, and salaried or benefited positions. Medians are reported only for those individuals reporting income from a given source, whereas the t-tests reflect the full sample (including those with $0 income from a given source). IQR = interquartile range.
