The focus groups and literature review that were conducted in 2001 were used for item generation in the development of the ITP-PAQ in the absence of a conceptual model [ 17].
The validated PedsQL™ module development guidelines, the consolidated criteria for reporting qualitative research (COREQ), and the FDA guidelines on PRO development were used to develop the methodology for item development and content validity [ 5, 16, 17, 20].
A fifth-grade reading level was maintained for item development.
This results in considerable costs for item development, pretesting, and item calibration (Veldkamp and Matteucci 2013).
The initially calibrated item bank that was used for the development of the CAT Fatigue RA consisted of 196 items and 3 dimensions, which included all 12 dimensions that emerged from the Delphi study.
The basic pool comprises 43 items used for subsequent scale development, which are reported in Table 2.> -wrap-foot> Items are written in order of appearance in the protocol questionnaire IONB-PRO 0.1.
The eight components of occupational balance identified in the qualitative analysis were used for the development of the questionnaire items, as shown in Table 2.
Concerning the items used for internal professional development, the categories of I observe how other teachers use ICT in teaching, I systematically collaborate with colleagues to develop ICT-based lessons based on the curriculum, and I work together with other teachers on improving the use of ICT in classroom teaching were drawn upon.
Content validity of the scales and items was evaluated utilising the conceptual framework used for measurement development.
3) Since we focused on the methods used for the development and validation process of self-efficacy instruments, a minimum of the development process had to be described such as item identification, item selection or construction of domains.
