Development and revision of the Wittmann-Price Emancipated Decision-Making Scale
Background And Purpose:
The original Emancipated Decision-Making (EDM) scale was revised to test 3 subconcepts (flexible environment, personal knowledge, and awareness of social norms) of an emancipated decision-making process.
Methods:
The original EDM scale was significantly related to the Satisfaction with Decision (SWD) scale in two separate studies (r = 0.79, r = 0.59). Two of the original 5 subconcepts showed a lack of contribution. The third study (N = 50) had good total scale reliability (r = 0.89).
Results:
The revised EDM (EDM-r) scale was then leveled to the SWD scores and quantified into 2 categories and the subscales for the 3 subconcepts were reanalyzed for reliability and scale-if-item contribution.
Conclusion:
The final EDM-r is a generically worded, 20-item, 3-subscale instrument with good total and individual subscale reliability.

Decision Making: P-value Method
First, a specific claim about the population parameter is proposed. The claim is based on the research question and is stated in a simple form. Further, an opposing statement to the claim is also stated. These statements can act as null and alternative hypotheses: a null hypothesis would be a neutral statement while the alternative hypothesis can...
