The work in this paper introduces finite mixture models that can be used to simultaneously cluster the rows and columns of two-mode ordinal categorical response data, such as those resulting from Likert scale responses. We use the popular proportional odds parameterisation and propose models which provide insights into major patterns in the data. Model-fitting is performed using the EM algorith...

OBJECTIVE The aim of the present study was to evaluate whether the Dougados Functional Index (DFI) with 5-point Likert scale is sensitive enough to demonstrate the efficacy of intensive physiotherapy and exercise. METHODS Eight-one consecutive patients with spondyloarthropathy (SpA) completed self-administered questionnaires on functional analysis, the Bath Ankylosing Spondylitis Functional I...

Falls in hospitals are common, therefore strategies to minimize the impact of these events in older patients and needs to be examined. In this pilot study, we investigate a movement monitoring sensor system for identifying bed and chair exits using a wireless wearable sensor worn by hospitalized older patients. We developed a movement monitoring sensor system that recognizes bed and chair exits...

OBJECTIVE We investigated elementary school children's ability to use a variety of Likert response formats to respond to concrete and abstract items. METHODS 111 children, aged 6-13 years, responded to 2 physical tasks that required them to make objectively verifiable judgments, using a 5-point response format. Then, using 25 items, we ascertained the consistency between responses using a "go...

OBJECTIVES Proper assessment of dyspnea is important in patients with heart failure. Our aim was to evaluate the use of the 5-point Likert scale for dyspnea to assess the degree of pulmonary congestion and to determine the prognostic value of this scale for predicting adverse events in heart failure outpatients. METHODS We undertook a prospective study of outpatients with moderate to severe h...

Cronbach’s Alpha coefficient is the most popular method of examining reliability. It is typically used when the researcher has several Likert-type items that are summed or averaged to make a composite score. Distribution of alpha coefficient has been subjected of many studies. In this study relationship between randomness and Cronbach alpha coefficient were investigated and in this context, pre...

PURPOSE To estimate the just-noticeable difference (JND) in ocular comfort rating by human, contact lens-wearing subjects using 1 to 100 numerical scales. METHODS Ostensibly identical, new contact lenses were worn simultaneously in both eyes by 40 subjects who made individual comfort ratings for each eye using a 100-point numerical ratings scale (NRS). Concurrently, interocular preference was...
