To better understand genetic, familial, and experiential contributions to competence and vulnerability, we have undertaken an epidemiological survey of personality development in twin children during the first six years of life. A series of new instruments has been created. This paper describes two questionnaire instruments and their validation: childhood personality scale, an instrument for reporting on a child's general personality and competence, and parent's report, an instrument designed to measure a parent's perception of his or her own parental style in relation to a particular child. The use of such instruments may help facilitate clinical communication about children and their parents and be of value in program evaluation and pediatric screening.
