Validity and reliability are two fundamental elements in the evaluation of a measurement instrument. Background Objective: The objective of the current study was to test the validity and reliability of the jaw and facial activities limitation questionnaire of orofacial pain patients. The five conceptions measured were those of repeated trials, evaluating the trustworthiness of data, treatment of anomalous data, internal and external validity of experimental design. Aims Home-CookERITM had excellent content and face validity with responding participants; all 24 questions were both clear and relevant (X2 (1, n = 19; 19.0, p = 0.392)). Obtained results were subjected to statistical analysis by the t-student test and X-square test with Yates correction (p<0.05). Home-CookERITM was further optimized by reduction to a 77-item version, which is now available to researchers. They indicate how well a method , technique or test measures something.

In order to achieve the objective of the study, a research framework had been developed to establish a relationship among the variables of the study based on resource-based view, strategic leadership theory and leader member exchange theory.
