The mean age of participants that completed the Teddy interview (M = 7.2, SD = 1.2) did not significantly differ from the full sample (M = 7.5, SD = 1.4), t(37) = −1.34, p = 0.188. Race distribution of the Teddy sample did not significantly differ from the distribution of the full sample, χ2(2) = 1.75, p = 0.417. Ethnicity distribution of the Teddy sample did not significantly differ from the distribution of the full sample, χ2(1) = 0.37, p = 0.541.
