“…Major contributions to the field concentrate on the verbal interventions of the therapist (e.g., Stiles, 1986Stiles, , 1987Winston, Samstag, Winston & Muran, 1994; see also the seminal work of Strupp, 1958aStrupp, , 1958bStrupp, , 1962, but do not focus on the nature of the processes that lead to these interventions and generally produce mixed (and often contradictory) results (Marziali, 1984;Piper, Azim, Joyce & McCallum, 1991). Other pioneering work has concentrated on the therapist's cognitive complexity (Holloway & Wolleat, 1980), on the therapist's types of mental functioning conceived of as personality traits (Goodwin, 1978), or on the cognitive match between patient and therapist (Hunt, Carr, Dagadakis, & Walker, 1985).…”
