To shed light on current controversy about whether interpretive interv
entions have a beneficial or counterproductive effect on the therapeut
ic alliance, the authors investigated the relation between type of the
rapist intervention (interpretation, confrontation, clarification, enc
ouragement to elaborate, empathic, advice-praise) and level of patient
collaboration, rating transcripts of single psychotherapy sessions fo
r thirty-nine patients. Higher proportions of interpretation and clari
fication were associated with better patient collaboration, whereas a
higher proportion of advice and praise was associated with poorer pati
ent collaboration. The findings underscore the therapeutic value of th
e patient and therapist jointly making psychological meaning of the pa
tient's material but also point to the need for an optimal blend of ex
pressive and supportive interventions.
