Multiple - family group therapy, a precursor of psychoeducational family intervention, emerged, in part, as a pragmatic alternative
form of intervention - especially as an adjunct to the treatment of

systemic» (and thus potentially «family - blaming») paradigms of pathogenesis that were implicit in many of the dominant models of family therapy.
