Further psychometric testing and use of the Maternal Confidence Questionnaire.

Research results can be better interpreted and used when reliable and valid instruments are used to measure concepts. Researchers and clinicians, especially those from locations outside the United States, have difficulty locating existing instruments for use in their research studies. The dilemma is further exaggerated when such instruments are not published and when the author of the instrument cannot be located. This review looked at the results of 20 studies which have utilized the Maternal Confidence Questionnaire (MCQ) (Zahr, 1991) with the purpose of familiarizing researchers and clinicians with its flexibility, reliability, and validity. Examples of specific published studies which have used the instrument are discussed along with unpublished studies which have used the instrument.
