  • * The table provides summary measures for both categorical and numerical variables. For categorical variables, the entry “%” gives the percentage of the sample with the given characteristic. For a numerical variable, the entry “mean” gives the mean value for the variable; the entry “(SD)” gives the standard deviation.

    An F test is used to test for significance, comparing across all three clinician types:

  • Significant at a P = .05.

  • Significant at a P = .01.

  • § Significant at a P = .001.

  • ** All “practice settings” summed together yielded more than 100% indicating that the categories were not mutually exclusive.
