Preliminary development and validation of the Patient-Physician Relationship Scale for physicians for disorders of gut-brain interaction

BACKGROUND: An effective patient-physician relationship (PPR) is essential to the care of patients with irritable bowel syndrome (IBS). After developing a PPR questionnaire for patients, we sought to develop and validate an IBS-specific instrument to measure physician expectations of the PPR. METHODS: We conducted focus groups about PPRs among 15 clinicians who treat patients with IBS from community and academic centers. Qualitative analysis was used to generate the Patient-Physician Relationship Scale-Physician RESULTS: The PPRS-Physician contained 35 questions pertaining to interpersonal and psychosocial features considered desirable or undesirable in a relationship with IBS patients. 1113 physicians (22%) completed the survey. Physicians were predominantly middle-aged (mean = 55.1 years), male (85.0%), white (74.5%), and practiced primarily within group settings (61.6%), with an average of 25.7% of their patients having IBS. Factor analysis revealed three relevant factors: interfering attributes, positive attributes, and personal connection. The scale ranged from possible 0 to 100 (mean = 83.8; SD = 8.38). Cronbach’s alpha reliability measure of the scale was 0.938, indicating high internal consistency. There was a significant moderate, positive correlation between JSPE and the PPRS (P < 0.001, r = 0.488), establishing concurrent validity. CONCLUSIONS: We describe the development and validation of the first questionnaire to measure physician expectations of the PPR. This instrument can be used clinically, and for future studies on physician communication.
