  • Data are means ± SD unless otherwise indicated (n = 196). P values reflect χ2 test and univariate tests for group differences. Time × treatment effects were never significant and therefore are excluded from the table.

  • * Level of education was measured on a 6-point scale (1 = primary to 6 = higher education).
