Reliability and Validity of Preschool Feelings Checklist.

The Preschool Feelings Checklist (PFC) is a 16-item parent report measure of depressive symptoms in young children. However, data on its reliability and validity are limited. We examined the internal consistency and convergent, discriminant, and predictive validity of the PFC in an unselected community sample of 490 3-year old children. Child psychopathology was assessed using semi-structured diagnostic interviews conducted with a parent at ages 3 and 6 (the Preschool Age Psychiatric Assessment) and with the child and a parent at ages 9, 12, and 15 (the Kiddie Schedule for the Affective Disorders and Schizophrenia, Present and Lifetime Version). The PFC exhibited good internal consistency. It was concurrently associated with depression, as well as a wide range of other psychiatric disorders and functional impairment. Similarly, the PFC at 3 years independently predicted depression and a range of other disorders and global functioning in subsequent assessments later in childhood and in adolescence. Finally, the PFC outperformed the longer Child Behavior Checklist in predicting diagnoses and functioning. Results support the concurrent and predictive validity of the PFC in preschoolers. However, it also exhibited concurrent and predictive associations with a number of other disorders, suggesting that it indexes a broad transdiagnostic liability for psychopathology and impairment.
