When comparing alpha values obtained for the Maltese study with other studies carried out 79 – 121621242930 Table 9 it was noted that despite the notion that alpha values of 0. Table 6 Principal component analysis using varimax rotation with Kaiser Normalisation.
Medicinnes further confirm factor loading, PCA was then carried out on the items in each beliwfs in order to verify that the items in each sub-scale were loading on one component.
Items G5 and G6 loaded on component 2 harm. Principal component analysis carried out on individual sub-scales to confirm factor loading.
By convention, acceptable internal consistency is proven by obtaining values of alpha that are over 0. Specific-Concerns scale assesses perceptions of the likelihood of adverse reactions as a consequence of taking qbout prescribed medication. Table 9 Comparisons of Internal consistency alpha values obtained in the Maltese study with the original and others published in different languages. The questtionnaire was collected and checked on completion. However, elimination of item S6 gave only minor gains with respect to the internal consistency of the tool.
Percentage of Beljefs explained This is the first study to assess psychometric properties of the BMQ in the Maltese language. Curr Pharm Teach Learn.
Table 7 Principal component analysis using varimax rotation with Kaiser Normalisation. Rheumatology Oxford ; 44 6: In the development of the BMQ, during confirmatory factor analysis, S6 had a loading of 0. After conducting PCA with restriction to two quesrionnaire, item S6 loaded on two components, with a loading of 0. Table 2 Demographic characteristics of study sample.

The back translation was reviewed against the English version so as to ensure conceptual equivalence of the translation carried out, avoiding mistranslations and translation losses which would render an incomplete replication qquestionnaire the source questionnaire in the target one.

Due to the items loading on different components, PCA was conducted with restriction to four factors, by loading each item on medicnies respective component, as was done in the Portuguese study 12 as presented in Table 8. In the Spanish study by De las Cuevas et al. The beliefs about medicines questionnaire: The patients selected were those with a confirmed diagnosis of asthma, diabetes, depression or cardiovascular disease.
The final solution for Principal Component Analysis yielded a four-factor structure representing the 4 sub-scales of the BMQ, with results being comparable to previous hmq out in different languages. Item G4 Natural remedies are safer than medicines was still problematic, giving a low factor loading of 0.

Due to the nature of the items loading, component 1 was identified as the General-overuse scale, with the items developed as representative of the overuse scale, G1, G4, G7, G8 all loaded on component 1. Therefore, patients with different levels of education should be targeted differently when counselling patients about their medicines. Harmonisation of this initial translation was carried out with the Department of Translation at the University of Malta, where items were discussed within the context to be measured, in an attempt to avoid literal translations which can mislead the purpose of the study.
J Eval Clin Pract. Eur Rev Appl Psychol. Italian Argentero et al. These anomalies in item-correlations were further investigated by re-calculating alpha after elimination of items G4 and G8 respectively and individually from the 4-item overuse scale. At this stage, a potential modification was considered on the overuse scale, where G4 would be eliminated from the scale. Theory and Practice in Language Studies.
