Note: SBTS = Stony Brook Temperament Study; CPDP = Child Personality Development Project (CPDP); NFTS = Northwestern Family Temperament Study; ICC = intra-class correlation; α = Cronbach’s Alpha; PE = positive emotionality; PA = positive affectivity; NE = negative emotionality.
ICCs are presented for directly observed behaviors (but not derived scores [i.e., PE and NE]). ICCs are based on 35 cases in the SBTS; 15 in the CPDP; and 27 in the NFTS. PA was indexed by the CBQ using the Smiling/Laughter scale. Sociability was indexed by the CBQ using the Shyness scale (reverse); Engagement was indexed by the CBQ using the Approach Anticipation scale.
