Observations of families in structured interactions: parenting therapists provide reliable ratings of mothers' parenting.

The reliability of observations of parenting by parenting therapists was assessed. An important predictor of externalizing behavior in children is quality of parenting. Data were videotapes of structured interactions in families with a child age 8-12 years referred to the evidence based Parent Management Training Oregon (PMTO) treatment program for child behavior problems. The therapists had clinical PMTO training but no training in systematic observation. PMTO observational coders with specific coder training were included as a reference for the therapists. Five therapists and two coders observed videotapes of 10 families and performed global evaluations of mothers' parenting skills. They used the coder's impression measure used in PMTO research. Scores were analyzed in a generalizability theory framework for the two groups of observers separately. Both observer types reliably rank-ordered the mothers and assessed the level of parenting skills. PMTO therapists without coder training provided reliable ratings of parenting constructs relevant to the clinical PMTO program in a manner comparable to that of the trained reference coders.
