1 The Second Leg: Clinical Expertise June 14, 2007

2 Clinical Expertise Defined Clinical expertise: the ability to use clinical skills and past experience to rapidly identify Clinical expertise: the ability to use clinical skills and past experience to rapidly identify each patient's unique health state and diagnosis each patient's unique health state and diagnosis individual risks and benefits of potential interventions individual risks and benefits of potential interventions personal values and expectations personal values and expectations

3 APA EBPP Definition Relevant issues: 1)Experts v. novices 2)Heuristics and biases 3)Cookbook formulation 4)Competency v. adaptive knowledge

4 Components of Clinical Expertise Assessment, diagnostic judgment, systematic case formulation, and treatment planning Clinical decision making, treatment implementation, and monitoring of patient progress Interpersonal expertise Self-reflection and life-long learning Evaluation of research evidence in basic and applied psychological science Understanding individual and cultural differences and their effects on treatment Seeking available resources Having a cogent rationale for clinical strategies

11 Blashfield and Flanagan JNMD, 1998 “age= 38, gender = female, marital status = single.” (*1*) “A 38-year-old woman was brought to an emergency room after attempting to kill herself by jumping in front of a subway train. (*2*) The woman had flat affect and spoke matter-of-factly during the interview. She said that the driver of the subway train had been her lover and that a major fear of these drivers was that someone would leap in front of their train in a suicidal act. (*3*) This lover had recently stopped seeing the woman after his wife learned of his affair and the wife had physically beaten up the patient in a nightclub. (*4*) The patient is an obese women of at least 250 pounds who works at a mortuary. She has been employed at the mortuary since the death of her mother.(*5*) Her mother and father were divorced when the patient was 15. Initially, the father won custody, but, when the patient kept running away from him, she was permitted to live with her mother. (*6*) She and her mother were very close. The mother contracted cancer, and the patient took care of her until her death. Then the patient requested a job with the mortuary that buried her mother. (*7*) Until recently, the patient had had no social life outside the mortuary. However, while riding the subway, she became fascinated with the voice of one driver and was determined to learn about this man. (*8*) She took leave from her job and managed to learn who the driver was, what his schedule was, and where he lived. She approached him and they became lovers. (*9*)”

14 Expert and Novice Treaters (Eells et al, (2005), JCCP) Expert, experienced, and novice tx Expert, experienced, and novice tx Expertise in psychotherapy is “ill structured” rather than “well-structured” as in chess Expertise in psychotherapy is “ill structured” rather than “well-structured” as in chess Psychodynamic and CBT Psychodynamic and CBT “Think aloud” case formulations of standard cases “Think aloud” case formulations of standard cases Experts’ formulations were more elaborated, comprehensive, complex, and systematic Experts’ formulations were more elaborated, comprehensive, complex, and systematic Experts treatment plans more directly tied to case formulations Experts treatment plans more directly tied to case formulations Effect size medium-large Effect size medium-large

15 Question If you were doing a study evaluating the relationship between therapist expertise and therapy outcome, how would you measure expertise? If you were doing a study evaluating the relationship between therapist expertise and therapy outcome, how would you measure expertise? If you were doing a study evaluating the relationship between therapist expertise and the therapy experience (viewed by the patient), how would you measure expertise? If you were doing a study evaluating the relationship between therapist expertise and the therapy experience (viewed by the patient), how would you measure expertise?

16 What does the literature say… About the relative importance of therapist, treatment, and patient variables in predicting outcome? About the relative importance of therapist, treatment, and patient variables in predicting outcome? Is there any empirical data on the implications of therapist expertise findings for education and training? Is there any empirical data on the implications of therapist expertise findings for education and training? How can supervision be structured to enhance development of expertise? How can supervision be structured to enhance development of expertise?
