It replicates previous studies showing the specificity of verbalizations depending on the speaker (client or therapist) and the phase of therapy, adding its relation to change measured at the level of process and final outcome. 7,009 speaking turns of clients and therapists, nested in 139 change episodes, were analysed regarding the use of the five Linguistic Basic Forms included in the Therapeutic Activity Coding System (TACS) through Hierarchical Modelling. Results show that three of these Linguistic Basic Forms — Question, Assertion and Agreement — are related to ongoing change as well as to final outcome.en-USPsychotherapy processVerbal communicationPsychological changeEx post facto studyTherapeutic outcomeArtículo
