How Representative of the Original Child Cohort Are the Adult Samples? Mean Childhood Factor Scores in Each of the Adult Samples
| Mean childhood factor scores | Standard deviations | ||||||||
|---|---|---|---|---|---|---|---|---|---|
| Male samples | Female samples | Male samples | Female samples | ||||||
| Factor | N=396 | N=375 | N=403 | N=387 | N=396 | N=375 | N=403 | N=387 | |
| Extraversion | .02 | .03 | -.04 | -.04 | 1.03 | 1.03 | 1.03 | 1.03 | |
| Agreeableness | .05 | .06 | .06 | .07 | .97 | .97 | .98 | .98 | |
| Conscientiousness | .09 | .10 | .13 | .12 | 1.04 | 1.03 | .99 | .98 | |
| Neuroticism | .07 | .06 | .00 | .00 | .98 | .97 | 1.02 | 1.02 | |
| Openness | .05 | .05 | .08 | .09 | .98 | .98 | 1.00 | 1.01 | |
Note. The mean values are deviations (in standard deviation units), for each of the adult samples, from the child cohort means (0.00), which were computed separately within the total childhood male and female samples; the sample standard deviations can be compared with the total childhood male and female cohort standard deviations of 1.00.
