By the mid-1960s a number of distinct schools of family therapy had emerged. From those groups that were most strongly influenced by cybernetics and systems theory, there came strategic therapy, and slightly later, Salvador Minuchin's Structural Family Therapy and the Milan systems model. Partly in reaction to some aspects of these systemic models, came the experiential approaches of Virginia Satir and Carl Whitaker, which downplayed theoretical constructs, and emphasized subjective experience and unexpressed feelings (including the subconscious), authentic communication, spontaneity, creativity, total therapist engagement, and often included the extended family. Concurrently and somewhat independently, there emerged the various intergenerational therapies of Murray Bowen, Ivan Böszörményi-Nagy, James Framo, and Norman Paul, which present different theories about the intergenerational transmission of health and dysfunction, but which all deal usually with at least three generations of a family (in person or conceptually), either directly in therapy sessions, or via "homework", "journeys home", etc. Psychodynamic family therapy - which, more than any other school of family therapy, deals directly with individual psychology and the unconscious in the context of current relationships - continued to develop through a number of groups that were influenced by the ideas and methods of Nathan Ackerman, and also by the British School of Object Relations and John Bowlby’s work on attachment. 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 serious mental disorders with a significant biological basis, such as schizophrenia - and represented something of a conceptual challenge to some of the "systemic" (and thus potentially "family-blaming") paradigms of pathogenesis that were implicit in many of the dominant models of family therapy. The late-1960s and early-1970s saw the development of network therapy (which bears some resemblance to traditional practices such as Ho'oponopono) by Ross Speck and Carolyn Attneave, and the emergence of behavioral marital therapy (renamed behavioral couple therapy in the 1990s) and behavioral family therapy as models in their own right
