Parental patterns of affective style and the development of schizophrenia spectrum disorders.

Measures of parental affective style of communication, based on direct family discussions, were obtained for a sample of 52 families of disturbed but nonpsychotic adolescents. When the variations of both parents on the measure for two different measurement contexts were combined, an accurate prediction of subsequent psychiatric status at follow-up occurred. Adolescents with at least one parent who consistently displayed a pathological affective style of communication in both a dyadic and triadic discussion developed schizophrenia-spectrum disorders as young adults. Conversely, adolescents with at least one parent who was consistently benign in affective style had healthier outcomes. Finally, more serious young adult psychopathology was noted where both parents were inconsistent in their affective style from dyadic to triadic interaction. Methodological implications for family interaction research are discussed.
