For studies that collect a quantitative measure of CPD, where the respondent is free to provide any integer (e.g., 13 CPD), '''we will bin responses into the following bins: 1-10, 11-20, 21-30, 31+.''' If some study collected binned responses from the outset, and those bins happen to differ from ours (e.g., 1-5, 6-15, etc.), then we will simply use whatever bins the study has collected. Please contact Scott if your study does something completely different.

Please note, however, that when we report descriptive statistics about our phenotypes we will want to report the original participant responses. Even though we'll bin the data for analysis, we'll still report quantitative CPD (when possible) when we describe each study's phenotype.
