Table 3. Interrater reliabilities of personality dimensions in the Kasekela community, the Mitumba community, and interrater reliabilities of individual ratings obtained in previous studies.

Dimension	Kasekela		Mitumba		ICC(3,1) estimates from previous studies
	ICC(3,1)	ICC (3,k)	ICC(3,1)	ICC(3,k)	King & Figueredo (1997)44	King et al. (2005)55	Weiss et al. (2007)47	Weiss et al. (2009)41
For the chimpanzees in the Kasekela community the mean number of raters per chimpanzee (k) was 3.00 (range: 2 to 5 raters per chimpanzee). For the chimpanzees in the Mitumba community the mean number of raters per chimpanzee (k) was 5.88 (range: 3 to 7 raters per chimpanzee). For the Mitumba chimpanzee rated by the same rater twice we treated each rating as coming from the same rater in these analyses.
