For both of these variables, each response category was transformed into adummy variable and further Chi-square tests were conducted. Results show thathaving a high school diploma was significantly associated with access totreatment, with subjects who completed high school being 1.39 times more likelyto access services than those who had not completed high school (Table 3).However, this effect size is small (Rosenthal, 1994).Table 3.

Although subjects who lived in their family’s homeor who lived in somebody else’s home were 1.38 and 1.65 times more likely toaccess treatment compared to subjects who lived elsewhere, these effect sizesare small (Rosenthal, 1994). In contrast, a moderately strong effect size wasobtained for “living in one’s own home”, with the inverted odds ratio indicating thatsubjects living in their own home were 3.4 times more likely to not accesstreatment compared to those living elsewhere.For continuous predisposing variables, significant differences were found betweencases and controls for “self-efficacy to stop using drugs for one month” and “self-39
