Background: Training therapists is both expensive and time-consuming. Degree-based training can require tens of thousands of dollars and hundreds of hours of expert instruction. Counseling skills practice often involves role-plays, standardized patients, or practice with real clients. Performance-based feedback is critical for skill development and expertise, but trainee therapists often receive minimal and subjective feedback, which is distal to their skill practice., Objective: In this study, we developed and evaluated a patient-like neural conversational agent, which provides real-time feedback to trainees via chat-based interaction., Methods: The text-based conversational agent was trained on an archive of 2354 psychotherapy transcripts and provided specific feedback on the use of basic interviewing and counseling skills (ie, open questions and reflections-summary statements of what a client has said). A total of 151 nontherapists were randomized to either (1) immediate feedback on their use of open questions and reflections during practice session with ClientBot or (2) initial education and encouragement on the skills., Results: Participants in the ClientBot condition used 91% (21.4/11.2) more reflections during practice with feedback (P<.001) and 76% (14.1/8) more reflections after feedback was removed (P<.001) relative to the control group. The treatment group used more open questions during training but not after feedback was removed, suggesting that certain skills may not improve with performance-based feedback. Finally, after feedback was removed, the ClientBot group used 31% (32.5/24.7) more listening skills overall (P<.001)., Conclusions: This proof-of-concept study demonstrates that practice and feedback can improve trainee use of basic counseling skills., (©Michael J Tanana, Christina S Soma, Vivek Srikumar, David C Atkins, Zac E Imel.

Psychotherapy can be an emotionally laden conversation, where both verbal and nonverbal interventions may impact the therapeutic process. Prior research has postulated mixed results regarding how clients emotionally react following a silence after the therapist is finished talking, potentially due to studying a limited range of silences with primarily qualitative and self‐report methodologies. A quantitative exploration may illuminate new findings. Utilising research and automatic data processing from the field of linguistics, we analysed the full range of silence lengths (0.2–24.01 s), and measures of emotional expression—vocally encoded arousal and emotional valence from the works spoken—of 84 audio recordings of Motivational Interviewing sessions. We hypothesised that both the level and the variance of client emotional expression would change as a function of silence length; however, due to the mixed results in the literature, the direction of emotional change was unclear. We conducted a multilevel linear regression to examine how the level of client emotional expression changed across silence length, and an ANOVA to examine the variability of client emotional expression across silence lengths. Results of both analyses indicated that as silence length increased, emotional expression largely remained the same. Broadly, we demonstrated a weak connection between silence length and emotional expression, indicating no persuasive evidence that silence leads to client emotional processing and expression.
