Notes: ¹Component loadings not in parentheses represent the component loadings for the PCA of users who had both a telephone contact and a consultation at the out-of-hours centre (n = 125). Component loadings in parentheses represent the component loadings for the PCA of users who had a consultation at the out-of-hours centre irrespective of whether they had telephone contact beforehand (n = 188). Items relating to telephone contact were not included in the latter PCA; ²45 of the 188 users who attended the out-of-hours centres did not see a nurse and hence omitted this section of the questionnaire.
