Development and validation of a measure of dental patient satisfaction.
As part of the Washington State Dental Auxiliaries Project, a 42-item measure of patient satisfaction with dental care was developed. The measure is comprised of 13 subscales: dentist-patient relations, technical quality of care, access, patient waiting time, cost, facilities, availability, continuity, pain, auxiliaries performing expanded duties, staff-patient relations, staff technical quality of care, and office atmosphere. The measure was developed from a set of 52 items included in a questionnaire administered to the patients of private dental practices in Washington state. Usable questionnaires were returned by 30.8% of patients receiving questionnaires in 1979, 40.1% in 1980, and 34.0% in 1981. Factor analysis plus categorization of items by a panel of professionals were used initially to group items into subscales. Contribution to internal consistency was the final criterion for an item's inclusion in a subscale. Internal consistency of subscales ranged from 0.44 to 0.80. The concurrent validity of subscales was assessed by relating patient satisfaction to characteristics of the dental practices. The following statistically significant relationships between subscales and criterion variables were observed: dentist-patient relations and percent of patients seen by the dentist; access and number of weeks appointments must be booked in advance; patient waiting time and actual patient waiting time; continuity of care and percent of patients seen by the dentist; auxiliaries performing expanded duties and delegation to auxiliaries; and staff technical quality and percent of hygienist restorations with satisfactory quality. Each relationship was in the expected direction.
