Factor analysis of 432 registered nurses' responses to three measures of the transactional analysis ego states of parent, adult, and child were run in order to develop shorter scales tailored to nurses. The analysis resulted in four 10-item scales labeled parent, adult, adapted child, and natural child. Reliability coefficients ranged from .79 to .85. Interscale correlations ranged from -.20 to .18. Means, standard deviations, and percentile scores were presented for each scale. Implications for nursing research are discussed.
