Denture wearer's perception of ambient care, part 1: validation of a preliminary scale

Abstract

Objective. The aim of the present study was to investigate if a preliminary Ambient Care Scale (ACS), intended to measure ambient care in complete denture wearers, had acceptable reliability and validity. Materials and methods. A sample of 117 patients who had received complete dentures in both jaws in the period 1997–2005 at Bergen School of Dentistry completed a questionnaire containing eight items regarding the patients’ relationship with the student and clinical personnel, to what extent they were informed and consulted during treatment, waiting times and cost. In addition, information was gathered regarding demographics, The Psychological General Well-Being index (WHO−5), global ambient care, satisfaction with dentures and how patients viewed their oral health. Results. Cronbach's alpha coefficient was 0.76 for the ACS, indicating acceptable internal consistency. From principle component analysis, three factors were extracted, correlating with ACS with coefficients of 0.72, 0.58 and 0.59, respectively. Acceptable construct validity was indicated by the fact that items were formulated by common agreement among three experienced prosthodontists, the extremely low frequency of missing data (<2%) and that ACS, as expected, was able to discriminate between patients satisfied and dissatisfied with their dentures (p = 0.005) and oral health (p = 0.042), but not between those who had high or low WHO-5 scores (p = 0.77). Conclusions. The ACS appears to have acceptable psychometric properties.
