Factor analyses using principal component analysis (PCA) are conducted, and the reliability of factor scores are evaluated with Cronbach's alpha.
Among the potential statistical drawbacks derived from the sample size are the increase in sampling error, instability, and reduced reliability of factor analysis solutions [ 46].
Poor reliability of Factor 6 (Specialist Generalist) may have been a reflection of questionnaire design as generalist work has been previously identified as favouring job satisfaction of rural AH professionals [ 43].
Figures 1, 2 and 3 show the results of the standardized factor loadings, correlations between the factors, reliabilities of factors and error term of variables (items of the questionnaire) of the CFA models with correlated factors.
The reliability of the factors was high: 0.89 for Factor 1 and 0.83 for Factor 2. 1- Job security and social status; 2 – Altruism and intellectual challenges; 3 - Existence of artistic theme in dentistry; 4 - Parents' recommendation.
We aimed to explore possible latent factors in the pool of POSM questions and reliability of these factors in order to better inform future use and reporting of the POSM questions.
A 3-factor has been shown for the LISAT-9 and a 4-factor structure for the LISAT-11 with internal consistency reliability of the factors between.57 and.79 (overall.85) [ 23, 53].
The internal consistency reliability of the factors for the full sample (n=1016) exceeded 0.80 for all six reduced factors from CFA-2 and are shown in table 1.
The construct reliability of the factors proposed for the model was 0.825, 0.908 and 0.880 for the respective factors F1, F2 and F3.
The construct reliability of the factors proposed for the model was 0.786, 0.832, 0.908, 0.743, and 0.810 for the respective factors F1, F2, F3, F4 and F5.
