  1. The CPS and Grit Scales are presented in z-scores to ease interpretation
  2. aThe question asks whether the individual has ever consumed any substance such as cocaine, heroin, ecstasy, or sniffed glue; it excludes marijuana consumption. The summary index of risk behavior is an equally weighted average of the z-scores of its components (i.e., the eight measures of risk behavior). The z-scores are calculated by subtracting the control group mean and dividing by the control group standard deviation
