Testing the reliability of a new measure of life events and experiences in childhood: The Psychosocial Assessment of Childhood Experiences (PACE).

There are few well validated instruments for measuring the impact of life events and experiences in childhood and adolescence. This study examines the reliability of a new instrument, the Psychosocial Assessment of Childhood Experiences of PACE. Fifteen children and parents were interviewed on two cassions ten days apart for the main test-retest reliability study. About half of the events recorded were reported on both occasions (0.45% and 0.55% concordance). When the impact of specific events was examined much higher levels of agreement were found. Inter-rater reliability tests also yielded higher rate (Kappa 0.74 and above). Possible reasons for these important differences are discussed and the inherent methodological difficulties considered.
