Table 2. Repeated measures analysis of covariance of health-care reimbursement costs for students with mental health problems (n=109).

NOTE: SBHC GROUP = 1 for students in non-SBHC schools, SBHC GROUP = 2 for students in SBHC schools, and SBHC GROUP = 3 for students who used SBHCs during the intervention period. Interaction effects between time and covariance variables include TIME*AGE, TIME*SEX, TIME*RACE, TIME*AFDC, TIME*SCHIP, TIME*DISABLED, TIME*MCO, and TIME*SBHC GROUP.

^aPrimary dependent variable = total health-care cost (reimbursement amount in 2003 dollars).

^bModel design = Intercept + SBHC GROUP + RACE + SEX + AGE + AFDC + DISABLED + SCHIP + MCO. Within-subjects design = TIME.

^cStatistically significant at alpha level 0.05

^dSecondary dependent variables = costs for mental health services (reimbursement amount in 2003 dollars), costs for prescription drugs, costs for hospitalization, and costs for emergency room visits.

DF = degree of freedom

F = Fisher's test statistic

AFDC = Aid to Families with Dependent Children

SCHIP = State Children's Health Insurance Program

MCO = managed care organization

SBHC = school-based health center
