“…Swensen (1967) has shown that therapist behavior differences can be usefully measured with an interpersonal interaction circle based upon combinations of active-passive and love-hate dimensions. Whereas factor-analytic procedures have been applied to study the separate and combined dimensions of therapist attitudes (McNair & Lorr, 1964;Sundland & Barker, 1962), the dimensions of ratings of small samples of therapist verbal behavior (Howe, 1962a(Howe, , 1962b(Howe, , 1964Howe & Pope, 1961a;Raush, Sperber, Rigler, Williams, Harway, Bordin, Dittman, & Hays, 1956;Zimmer & Anderson, 1968;Zimmer & Park, 1967), and the dimensions of client perceptions of therapists (Lorr, 1965), factor-analytic procedures remain to be applied to the hypothesized dimensions of overt therapist interactive behavior. Such a study should be based upon correlations among individual scales in a large heterogeneous therapist sample which represents all known sources of variance (e.g., professional grouping, experience level, therapist sex; see McNair & Lorr, 1964, p. 271).…”
