Early temperament as a predictor of language skills at 40 months

BMC Pediatrics

Table 4 Associations of subscales of the Early Child Behavior Questionnaire and receptive language scores at 40 months: regression coefficients in z-score (change in SD), 95% confidence intervals and p-values

Note. Model 1 = Univariate; Model 2 = Adjusted for other subscales of the Early Child Behavior Questionnaire Subscales (ECBQ); Model 3 = Model 2 with further adjustment for child sex, birth weight, gestational age at birth, birth order, age of the mother, years of maternal education, annual household income, maternal history of mood/anxiety disorders. CI Confidence intervals. Bold types represent p < .0013. The regression coefficients shown in Table 4 indicate the amount of predicted change in the z-score of receptive language skills per one unit of change in each of the ECBQ subscales. Again, this implies that a child scoring 7 (maximum) in motor activation, for example, was predicted to score − 0.225 × 6 (7 minus 1 point in the subscale) = − 1.350 points, corresponding to − 1.350 SD higher lower in the receptive language skills score at 40 months compared with a child scoring 1 (minimum)
