- Scientific TitleWatching a video of a medical consultation versus participanting in a medical consultation: Are effects on subjects comparable?
- ACRONYM
- hypothesisThe overall goal of this study is to test if the analogue patient paradigm is a valid method to assess the effects of physician-patient communication. More specifically, in Phase I, we aim to test if viewing a role-played interview about a common medical problem on video leads to comparable psychological and physiological responses as participating in this role-played consultation. If this is indeed the case, it provides support for testing the effects of different communication styles in medical interaction in a rigorous experimental design where the actual interaction process can be replaced by a video of interaction. The objective of Phase II is to test whether this so-called ‘analogue patient paradigm’ is a reliable and valid method to test the effects of different types of communication on subjects’ outcome measures.

- InterventionsA two-phase partly observational, partly experimental study with a mixed within- and between subjects design. In phase I, 30 healthy subjects will participate in a role-played interaction with an interviewer to simulate a medical consultation and subsequently watch their own conversation on video. In phase II, four videos from Phase I will be slected which differ in physician's communication style (showing affect and raising expectations). In a 2x2 experimental design, 320 subjects will randomly watch one out of the four video consultations. In both phases before and after the video-viewing several psychological and physiological (phase I only) will be taken.
- Primary outcomeThe study's primary parameters are affective, physiological (phase I only) and cognitive responses measured as state anxiety, and outcome expectations about the simulated illness in the interview. The study endpoint is the concordance of these measures between 1) subjects participating in the interview and subjects re-viewing their own interview and 2) between subjects participating in an interview and other participants (not participating in any interview) viewing interviews of others.
- Secondary outcomeSecondary study parameters are heart rate, positive and negative affect and illness perceptions about the simulated illness in the interview. Demographic variables, health status, trust in healthcare, communication preferences and empathic ability will be measured as control variables.
- TimepointsParticipants have to fill in a questionnaire at home aimed to assess their background characteristics. Before the experiment (Timepoint 0), background characteristics are assessed and participants' affective and cognitive responses are measured (resp. using the PANAS and STAI-state, and the IPQ-R). Then participants are randomly allocated to one of the four video consultations. After having seen the video (Timepoint I) participants again complete the PANAS, STAI-S and IPQ-R, and also the QUOTE-COM and CARE to asses communication preferences.

- Brief summaryCommunication between provider and patient is an essential element of medical care with regard to patient outcomes. To assess causal relationship between specified elements in providers’ communication and patient outcomes, controlled experiments are needed. One method is to use analogue patients, in which lay people are asked to watch a video consultation and identify with the video patient. However, the validity should yet be established. This study aims to assess whether the ‘analogue patient paradigm’ is a valid methodology to assess the specific effects of providers’ communication on patient outcomes. Therefore, a two-phase partly observational, partly experimental study with a mixed within- and between subjects design will be conducted. In phase I, 30 healthy subjects will participate in a role-played interaction with an interviewer to simulate a medical consultation and subsequently watch their own conversation on video. In phase II, four videos from Phase I will be selected which differ in physician's communication style (showing affect and raising expectations). In a 2x2 experimental design, 320 subjects will watch randomly one out of the four video consultations. In both phases before and after the video-viewing several psychological and physiological (phase I only) will be taken.
