A questionnaire on treatment satisfaction and disease specific knowledge among patients with acute coronary syndrome. I: Are treatment satisfaction and disease specific knowledge continuous latent traits?


Frick, Ulrich; Wiedermann, Wolfgang; Gutzwiller, Felix (2012). A questionnaire on treatment satisfaction and disease specific knowledge among patients with acute coronary syndrome. I: Are treatment satisfaction and disease specific knowledge continuous latent traits? Patient Education and Counseling, 86(3):360-365.

Abstract

OBJECTIVE:
To assess psychometric properties of a questionnaire covering treatment satisfaction and disease-specific knowledge among patients discharged after treatment for acute coronary syndrome.
METHODS:
Comparative scaling of the questionnaire using latent class analysis (LCA) and exploratory factor analysis (EFA) in a consecutive sample of 2015 patients.
RESULTS:
LCA revealed four qualitatively differing patterns of patients' knowledge and five distinct patterns of treatment satisfaction. EFA for patients' knowledge identified four uncorrelated "dimensions". Patient satisfaction was scored in a two-factor solution despite proven heterogeneity of persons.
CONCLUSIONS:
LCA was helpful to identify classes of patients that cannot be scaled according to a latent trait model.
PRACTICE IMPLICATIONS:
Specific patterns of insufficient disease-specific knowledge and satisfaction requiring specific interventions became visible.

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
