Notes ( ) = standard deviation, [ ] = weighted estimate of mean or proportion. (I) = informant based and (S) self-report measure. Sample size varies from measure to measure ranging between (a) 29-43, (b) 51-63 and (c) 11-17 for researcher assessed and informant based measures and (d) 26-29 and (e) 7 for self-report measures. Maternal education was coded as 1 = Graduate education, 2 = Completed college, 3 = Some college, 4= Completed high school, 5 = Did not complete high school; Work was coded as 1 = Paid full time, 2 = Paid part time, 3 = In education, 4 = Paid supervised position, 5 = Unpaid work, 6 = Day center, 7 = No work activities outside the home; Living was coded as 1 = Independent, 2 = Home with parents, 3 = Group home/Supported living; Friend was coded as 0 = One or more true friends, 1 = Peers, but limited interactions, 2 = Acquaintances only, 3 = No friends.
