Summary
The Shared Decision-Making Inventory-Revised (SDMI-R) demonstrates strong reliability for assessing school nurses' knowledge, attitudes, self-efficacy, and intent regarding human papillomavirus (HPV) vaccination discussions.
Area of Science:
- Health education
- Psychometrics
- Vaccine communication
Background:
- Effective communication is crucial for human papillomavirus (HPV) vaccination uptake.
- School nurses play a key role in discussing HPV disease and vaccination with clients.
- Validated instruments are needed to assess healthcare providers' readiness for shared decision-making.
Purpose of the Study:
- To evaluate the psychometric properties of the Shared Decision-Making Inventory-Revised (SDMI-R).
- To assess the SDMI-R's ability to measure knowledge, attitudes, self-efficacy, and intent related to HPV vaccine discussions.
- To determine the reliability and validity of the SDMI-R for use with school nurses.
Main Methods:
- The SDMI-R was administered to a sample of 1,525 school nurses.
- Internal reliability was assessed using Cronbach's alpha.
- Exploratory factor analysis was conducted to examine the instrument's structure.
Main Results:
- The SDMI-R demonstrated satisfactory reliability for the total instrument (α = .874) and key subscales (Attitude: .828, Self-Efficacy: .917, Intent: .891).
- Correlational analyses indicated moderate to strong correlations, supporting adequate internal reliability.
- Exploratory factor analysis identified five components explaining 75.96% of the variance.
Conclusions:
- The SDMI-R is a reliable and valid instrument for measuring school nurses' readiness for shared decision-making regarding HPV vaccination.
- Findings support the use of the SDMI-R to enhance HPV vaccine communication strategies.
- Further research can explore the SDMI-R's application in diverse clinical settings.

01:22Self-Report Tests of Personality
Self-report inventories are objective personality assessments that use multiple-choice items or numbered scales, typically ranging from 1 (strongly disagree) to 5 (strongly agree). They are often called Likert scales after Rensis Likert. These inventories are widely used due to their ease of administration and cost-effectiveness. One of the most prominent examples is the Minnesota Multiphasic Personality Inventory (MMPI), initially developed in the 1940s to assess abnormal personality traits.
01:09Decision Making: P-value Method
The process of hypothesis testing based on the P-value method includes calculating the P- value using the sample data and interpreting it.
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 have a...

01:29Self-Evaluation Maintenance Model
The Self-Evaluation Maintenance (SEM) model offers a psychological framework to understand how individuals’ self-esteem is influenced by the achievements of others, particularly those with whom they share close personal bonds. The SEM model operates when personal rather than social identity guides individuals. Central to this model is the notion that individuals have an inherent desire to preserve a favorable self-image, which is continuously shaped by interpersonal comparisons and...
01:14Decision Making: Traditional Method
The process of hypothesis testing based on the traditional method includes calculating the critical value, testing the value of the test statistic using the sample data, and interpreting these values.
First, a specific claim about the population parameter is decided based on the research question and is stated in a simple form. Further, an opposing statement to this claim is also stated. These statements can act as null and alternative hypotheses, out of which a null hypothesis would be a...
