Summary
This study validated a 14-item scale for assessing nursing students' attitudes toward handheld decision support software. The scale demonstrated good reliability and identified three key factors influencing user perceptions.
Area of Science:
- Nursing Education
- Health Informatics
- Psychometrics
Background:
- Handheld decision support software is increasingly used in healthcare.
- Assessing user attitudes is crucial for effective implementation.
- Validated psychometric tools are needed to measure these attitudes.
Purpose of the Study:
- To evaluate the psychometric properties of a 14-item scale assessing attitudes toward handheld decision support software.
- To determine the reliability and validity of the scale in a nursing student population.
Main Methods:
- A principal components factor analysis was performed on data from 103 nursing students.
- Internal consistency reliability was assessed using Cronbach's alpha.
Main Results:
- Factor analysis yielded three factors explaining 55.1% of the variance.
- Internal consistency reliability coefficients ranged from .71 to .83, indicating good reliability.
Conclusions:
- The 14-item scale is a reliable and valid instrument for measuring nursing students' attitudes towards handheld decision support software.
- The identified factors provide insight into user perceptions and can inform software design and training.

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.
01:27Halo Effect
The halo effect is a cognitive bias in which an individual's overall impression influences judgments about their specific traits. This psychological phenomenon leads people to associate positive characteristics with those they perceive as generally good and negative characteristics with those they view as bad. This effect is particularly influential in social perception, professional evaluations, and decision-making processes.The Psychological Basis of the Halo EffectThe halo effect is rooted...
