[Clearly show abstract] [Cover abstract] ABSTRACT: This paper describes the development process and evaluation of assemble validity proof of a Brazilian lecturersÂ’ collective efficacy instrument.

The vast majority of individuals inquiring about building this type of scale are statistical newcomers and would not have the option to deal with a technique as complicated as ordinal logistic regression, so the aim is to convert the Likert scale objects into an individual interval variable.
