Table 2. Comparison of the subtype groups on measures of functioning.

Measure	Hyperactive impulsive	Combined	Inattentive	F	P
Number of jobs	10.00a	9.29a	8.45a	0.76	0.47
	(8.52)	(9.13)	(10.26)

	(4.64)	(11.95)	(17.22)

SD in parentheses. For F tests, df = (2.688). For Welch test, df=(2.56.98)

^ab: groups with different subscripts are significantly different, P≤0.05.

¹Welch, Brown-Forsythe and Tamhane's T2 tests used due to unequal variances. Welch F statistic is reported rather than ANOVA.
