Development and psychometric validation of a new patient satisfaction instrument: The osteoARthritis Treatment Satisfaction (ARTS) questionnaire

Abstract

Given the increasing interest in treatment satisfaction research and the lack of a specific questionnaire in osteoarthritis (OA), we developed and explored the psychometric properties of the osteoARthritis Treatment Satisfaction (ARTS) questionnaire. The ARTS questionnaire which consists of 18 items was developed in French following the analysis of semi-structured interviews performed among 20 OA participants, five rheumatologists and five general practitioners. Psychometric properties were assessed in France on a cross-sectional sample of 797 OA participants and test-retest reliability was evaluated in an independent sample of 111 clinically stable OA participants who filled-in the questionnaire within a 7.7 (+/- 3.1) day interval. Using principal component analysis, four scales were identified: Treatment advantages (seven items), Treatment convenience (three items), Treatment confidence (two items) and Satisfaction with physician (six items). Item convergent and item discriminant validity were satisfactory. Internal consistency provided evidence of reliability and lack of redundancy (Cronbach's alphas ranged from 0.66 to 0.86). Test-retest reliability was acceptable for two out of four scales (intraclass correlations coefficients (ICC) ranged from 0.61 to 0.75). Significant between groups differences were found on the ARTS scales, demonstrating the known groups validity of the ARTS questionnaire. The responsiveness of the ARTS is still to be documented.

Development and preliminary validation of a Greek-language outpatient satisfaction questionnaire with principal components and multi-trait analyses

“…In fact, it has been observed that patients who have better health report generally higher satisfaction. We have therefore statistically examined this external aspect of validity -often termed "known groups validity" [ 42 ]- by reporting correlations of the various scales with the specific characteristics. We have employed in addition to Pearson measures, the Spearman's rank correlation coefficient to account for the possibility of non-normality (skewness) in individual items and the scale scores [ 41 , 43 ].…”

Development and Pretesting of a Questionnaire to Assess Patient Experiences and Satisfaction with Medications (PESaM Questionnaire)

“…Fourteen disease-specific measures relating to a wide range of illnesses and conditions were identified that could serve as examples for our PESaM questionnaire: intraocular pressure [ 45 , 46 ], osteoporosis [ 47 ], schizophrenia [ 48 ], diabetes [ 49 ], migraine [ 50 ], asthma [ 51 , 52 ], osteoarthritis [ 53 ], pain [ 54 , 55 ], Crohn’s disease [ 56 ], overactive bladder [ 57 ] and cancer [ 58 ]. Some measures focused on a specific type of treatment (e.g.…”

Brief Reflections on Treatment Satisfaction

“…With respect to health, consumer satisfaction was also the first area of study, where such variables as satisfaction with the physician, overall care, or time kept waiting were considered in evaluating the overall quality of care [1]. More recently, treatment satisfaction has become a focus of study, leading to the inevitable development of new disease-specific measures, such as the OsteoArthritis Treatment Satisfaction Questionnaire [2], a measure of treatment satisfaction in erectile dysfunction [3], as well as a broader, generic measure of satisfaction with medication, the Treatment Satisfaction Questionnaire Medication [4]. Theoretical work, which ought to be leading the way in this new field, has not kept pace [5].…”
