Principal component analysis Scree plots

The 55-item Likert scale was analysed using a principal components analysis and inspection of the scree plot indicated that six factors be rotated. A varimax rotation was performed on the six factors and the orthogonal factors generated are shown in Table 2. To create factor scores, item scores were aggregated for each factor and Cronbach s alphas were calculated to establish their reliability five of the factors had high enough alphas to allow the aggregated factors to be used in further analyses, and these factors are those shown in table 2. Factor 5 was difficult to interpret and had an alpha of only. 435, so it is omitted.
