No relation between the response groups characteristics and the scores as defined by factor analyses of Q1 and Q2 was found to be relevant and significant.
What's more, the 3-factor construction obtained from the exploratory factor analyses was tested by confirmatory factor analyses and it was seen that the tested model was confirmed with high fit indices.
The phase 2 PCA, with a revised pool of 48 items, indicated that four rather than five domains presented the best model giving rise to the 34-item PTOPS, which was supported by factor analyses conducted with phase 2 and phase 3 data which confirmed the independence of the domains providing evidence for the internal validity of the PTOPS scores.
Cronbach's alphas are between 0.7 and 0.9 for 16 of 20 domains and sub-domains (identified by factor analyses), indicating good internal consistency (Table 1).
The questionnaire has high internal consistency, with Cronbach's alphas between 0.7 and 0.9 for 16 of 20 domains and sub-domains (identified by factor analyses).
The WHO/McMaster Questionnaire on Providers' use of Research Evidence has acceptable levels of internal consistency for 16 of 20 domains and sub-domains (identified by factor analyses).
It contains 99 problem items, split into 7 subcategories: emotionally reactive, anxious/depressed, somatic symptoms, withdrawn, sleep problems, attention problems and aggressive behaviour originally derived by factor analyses.
These symptoms have been shown to be discriminated by factor analyses in the independent dimensions of interpersonal deficit, cognitive-disorganization deficit, and paranoid symptoms [ 7, 8].
The relationship between risk assessment behaviour and avoidance behaviour was found to be independent as shown by factor analyses [ 38, 39] Furthermore, it has been shown that risk assessment behaviour is very sensitive to anxiolytic drugs [ 40].
By applying exploratory factor analyses and regression models to the survey data, nine of the questions were mapped to five related characteristics of design thinking: collaboration, experimentalism, optimism, feedback-seeking, and integrative thinking.
