SE = standard error. Ratings on the original scales (ranging from 5–15 for examiners and 3–9 for parents) were rescaled (to 0–10 and 0–6, respectively) by subtracting the scores from the maximum of the corresponding scale, so that zero scores correspond to no deficits in social-communication. Latent class growth models for count data were fitted to the rescaled data.
