Summary
A new PrEP Empowerment scale shows reliability and validity, linking empowerment to better adherence. This measure helps understand factors influencing effective pre-exposure prophylaxis use.
Area of Science:
- Public Health
- Behavioral Science
- Clinical Medicine
Background:
- Pre-exposure prophylaxis (PrEP) is a key HIV prevention strategy.
- Understanding factors influencing PrEP adherence is crucial for its effectiveness.
- The Health Care Empowerment Model provides a framework for patient engagement.
Purpose of the Study:
- To develop and assess a measure of PrEP Empowerment.
- To examine the reliability and validity of the PrEP Empowerment scale.
- To explore associations between PrEP Empowerment, stigma, self-efficacy, and adherence.
Main Methods:
- A survey was administered to 100 participants during clinic visits.
- Plasma tenofovir (TFV) levels were measured in 84 participants to assess adherence.
- A five-factor measure was analyzed for variance, reliability, and validity.
Main Results:
- The developed PrEP Empowerment measure demonstrated a five-factor structure explaining 70% of the variance.
- Preliminary reliability and validity of the scale were supported.
- Associations with internalized PrEP stigma, adherence self-efficacy, and plasma TFV levels were significant.
Conclusions:
- PrEP Empowerment is a multidimensional construct with preliminary evidence of reliability and validity.
- The measure shows promise for assessing patient empowerment in PrEP care.
- Further research is recommended with diverse populations to enhance generalizability.

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.

Social psychologists have documented that feeling good about ourselves and maintaining positive self-esteem is a powerful motivator of human behavior (Tavris & Aronson, 2008). In the United States, members of the predominant culture typically think very highly of themselves and view themselves as good people who are above average on many desirable traits (Ehrlinger, Gilovich, & Ross, 2005). Often, our behavior, attitudes, and beliefs are affected when we experience a threat to our...

One influential perspective on what motivates people's behavior is detailed in Tory Higgin's self-discrepancy theory (Higgins, 1987). He proposed that people hold disagreeing internal representations of themselves that lead to different emotional states.

01:29Reliability and Validity

Reliability and validity are two important considerations that must be made with any type of data collection. Reliability refers to the ability to consistently produce a given result. In the context of psychological research, this would mean that any instruments or tools used to collect data do so in consistent, reproducible ways.

Some researchers suggest that altruism operates on empathy. Empathy is the capacity to understand another person’s perspective, to feel what he or she feels. An empathetic person makes an emotional connection with others and feels compelled to help (Batson, 1991). Empathy can be expressed in several ways, including cognitive, affective, and motor.

According to Charles Cooley, we base our image on what we think other people see (Cooley 1902). We imagine how we must appear to others, then react to this speculation. We don certain clothes, prepare our hair in a particular manner, wear makeup, use cologne, and the like—all with the notion that our presentation of ourselves is going to affect how others perceive us. We expect a certain reaction, and, if lucky, we get the one we desire and feel good about it. But more than that, Cooley...
