Study on the validity and reliability of Melbourne Decision Making Scale in Turkey
Open accessAbstract
This study is to analyze the validity and reliability of Melbourne Decision Making Questionnaire (MDMQ). The sample consisted of 650 university students. The structural validity of the MDMQ, as well as correlations among its sub-scales, measure-bound validity, internal consistency, item total correlations and test-retest reliability coefficients were determined. A confirmatory factor analysis found that the measure was compatible with the five sub-dimensions as depicted in the original scale and all items were well-placed in related sub-scales. Additionally, Cronbach’s alpha coefficient was found for the sub-scales such as self-esteem, vigilance, buck-passing, procrastination and hypervigilance .80, .82, .77, .75 and 79 respectively. In the same vein, test-retest consistency was rated as .82, .75, .83, .71 and .72. In the light of this statistical analysis, MDMQ has proven to be a valid and reliable measuring scale for determining levels of self-esteem and decision-making styles of university students. Key words: Decision making, decision making style, decision making questionnaire.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
