Process of validating a questionnaire

The items on the Spirituality Questionnaire (SQ) revealed factor loading ≥ 0.5.Reliability processes indicated that the SQ is reliable: Cronbach’s alpha 0.94 for the global SQ and between 0.80-0.91 for the four subscales.For example, if you are performing a time critical experiment, you will be using some type of stopwatch.Generally, it is reasonable to assume that the instruments are reliable and will keep true and accurate time.External validity is the process of examining the results and questioning whether there are any other possible causal relationships.Control groups and randomization will lessen external validity problems but no method can be completely successful.Together, they are at the core of what is accepted as scientific proof, by scientist and philosopher alike.

Validity encompasses the entire experimental concept and establishes whether the results obtained meet all of the requirements of the scientific research method.You can use it freely (with some kind of link), and we're also okay with people reprinting in publications like books, blogs, newsletters, course-material, papers, wikipedia and presentations (with clear attribution).The purpose of the paper is to describe the processes undertaken to evaluate the psychometric properties of a questionnaire developed to measure spirituality and examine the relationship between spirituality and coping in young adults with diabetes.This is why the statistical proofs of a hypothesis called significant, not absolute truth.Any scientific research design only puts forward a possible cause for the studied effect.
