Summary
Shared decision-making (SDM) tools are crucial for patient-physician communication. This review identified 18 instruments, but many require further validation for diverse healthcare settings.
Area of Science:
- Health Services Research
- Patient-Centered Care
- Medical Communication
Background:
- Shared decision-making (SDM) is increasingly recognized as vital for effective patient-physician communication and collaborative decision-making.
- Conceptual diversity in SDM presents challenges in consistent measurement, defining SDM's relationship with outcomes, and cross-study comparisons.
Purpose of the Study:
- To conduct a literature search for psychometric instruments measuring aspects of patient decision-making.
- To identify and review available tools for assessing shared decision-making processes and outcomes.
Main Methods:
- Systematic literature search for psychometric instruments related to decision-making.
- Analysis of identified scales focusing on patient perspectives, psychometric validation, and scope.
Main Results:
- A total of 18 scales measuring decision-making aspects were identified.
- Most scales focus on patient preferences for information/participation, decisional conflict, self-efficacy, and evaluation of the decision-making process.
- Significant variation exists in the psychometric validation of the identified scales.
Conclusions:
- A variety of instruments exist to measure aspects of decision-making and shared decision-making.
- Further research is needed to establish the psychometric quality and applicability of many existing decision-making instruments across different 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.
01:14Decision 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...

01:29Measures of Intelligence
Psychologists measure intelligence by using standardized tests that produce a score known as the intelligence quotient or IQ. To understand IQ tests, it's important to recognize the key principles behind their construction: validity, reliability, and standardization.
Validity refers to how well a test measures what it claims to measure. An intelligence test should accurately assess intelligence rather than another characteristic, like anxiety. Criterion validity is one way to evaluate this; it...

01:30Psychosurgery
Psychosurgery, the surgical alteration or permanent removal of brain tissue to alleviate severe psychological conditions, stands as one of the most radical and controversial treatments in the history of mental health care. Its development and application have evolved significantly, marked by dramatic shifts in scientific understanding and ethical perspectives.

01:23Wechsler's Contribution to Measures of Intelligence
David Wechsler, a psychologist who worked with World War I veterans, developed a significant IQ test in 1939 called the Wechsler-Bellevue Intelligence Scale. This test was innovative because it combined several subtests that measured both verbal and nonverbal skills, reflecting Wechsler's belief that intelligence is a global capacity involving purposeful action, rational thinking, and effective interaction with the environment. This test later evolved into the Wechsler Adult Intelligence Scale...
01:24Strategies of Self-Presentation III: Self-Monitoring
Self-monitoring is a central construct in understanding individual differences in self-presentation strategies across social contexts. It refers to how individuals observe, regulate, and control their expressive behavior and self-presentation following situational cues. Self-monitoring reflects a person's sensitivity to social appropriateness and willingness to adapt behavior to fit varying interpersonal demands.High vs. Low Self-Monitoring IndividualsIndividuals high in self-monitoring are...
