ABSTRACT
OBJECTIVES: To assess whether Interactive Guided Imagery (IGI) is helpful to medical patients and to identify factors that contribute to positive outcomes. DESIGN: A prospective cohort study of 323 medical patients who received 6 IGI sessions on a weekly basis. Patients and practitioners completed questionnaires at the beginning, middle, and end of the 6 IGI sessions. The questionnaires assessed the patients' ability to do IGI, the quality of the practitioner-patient interaction, possible confounding variables, and enabling factors. The hypothesis was that measures of the process of doing IGI and the practitioner-patient relationship would predict outcomes. SUBJECTS/SETTING: The subjects were all patients seeking treatment at California Pacific Medical Center in San Francisco, and Marin General Hospital in Greenbrae, CA. INTERVENTION: Using IGI interactively is a cognitive-behavioral intervention designed to help patients relax by using mental images to discover and cultivate healing intentions, and to reflect on the meaning of these images. MEASURES: The individual measures to assess the patients' ability to do IGI and measures of the practitioner-patient relationship were factor-analyzed to use as predictor variables in a multiple regression. Similarly, the questionnaire items measuring cognitive, emotional, behavioral, and spiritual benefits of IGI were factor-analyzed into factors representing "insight" and "all other" benefits. RESULTS: The multiple regression shows that both process and practitioner-patient interaction factors significantly contributed to a combined 40% of the variance in patients' ratings of insight into the nature of their problem and to becoming aware of an aspect of self, F(4,56) = 9.4, p < 0.005. The same process and interaction factors were less strongly related to the other outcomes, r2 = 0.14, F(4,56) = 2.3, p = 0.06. None of the demographic, confounding, or enabling factors was related to the outcome measures. CONCLUSIONS: The process of doing IGI and the relationship with the practitioner were both independently associated with the patients' insight into their health problems.
