Reliability and Validity of a Perinatal Shared Decision-Making Measure: The Childbirth Options, Information, and
Objective:
To develop and test the psychometric properties of a shared decision-making tool: Childbirth Options, Information, and Person-Centered Explanation (CHOICEs).
Design:
Multiphase instrument development study beginning with item development through a cross-sectional postpartum survey.
Setting:
The cross-sectional postpartum survey was distributed online through convenience and snowball sampling methods.
Methods:
We developed instrument items through an iterative process with key stakeholders. We evaluated reliability based on internal consistency and differential item functioning analysis. We evaluated validity on evidence of construct validity. We used criterion-related item mapping to evaluate whether the measure addressed the full spectrum of shared decision making related to maternity care.
Results:
Surveys were completed by 1,171 participants. A Cronbach's α coefficient of .99 supported internal consistency reliability. Infit and outfit statistics that ranged from 0.92 to 1.55 supported item fit. Differential item functioning analysis showed that CHOICEs scores were invariant between different demographic groups. Significant positive correlations between scores on CHOICEs and the Mothers on Respect index (r = 0.75, p = .01) and the Mothers Autonomy in Decision-Making scale (r = 0.75, p = .01) supported criterion-related validity. Item mapping suggested more items were needed to capture the full spectrum of shared decision making.
Conclusion:
We recommend using CHOICEs to evaluate shared decision making in maternity care for research and quality improvement projects.

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...

Authoritarian Parenting
This style is strict and controlling, with little room for open dialogue. Authoritarian parents demand obedience and often enforce rules with minimal warmth. Children raised this way may lack social skills and initiative, usually comparing themselves to others unfavorably.
