Summary
Many surgical research articles incorrectly cite "face validity" as evidence. Validity theorists universally agree face validity is not a real type of evidence, impacting research trustworthiness.
Area of Science:
- Surgical research methodology
- Scientific validity theory
Background:
- The American Journal of Surgery (AJS) has a long history of publishing high-quality surgical research.
- A review of AJS articles since 2006 revealed 30 instances of researchers citing "face validity" as evidence.
- This practice is problematic for the integrity of surgical research.
Discussion:
- Validity theorists have established that "face validity" is not a recognized form of validity evidence.
- The continued citation of face validity in surgical literature undermines the rigor of research findings.
- This highlights a gap in the understanding and application of established validity principles within the surgical community.
Key Insights:
- "Face validity" is not a scientifically accepted type of validity evidence.
- Misapplication of validity concepts can compromise the perceived trustworthiness of published surgical research.
- There is a need for improved education on validity theory for surgical researchers.
Outlook:
- Encouraging surgeons to consult current validity theory literature is crucial.
- Promoting accurate articulation of research trustworthiness will enhance the quality of surgical publications.
- Fostering informed consumption of research is essential for advancing the field of surgery.

14.3K
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.

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...

Appearance is a multidimensional aspect of self-presentation that encompasses observable attributes such as clothing, grooming, speech, and nonverbal behavior. These elements are often strategically managed to align with socially constructed expectations in different settings. For instance, individuals tailor their appearance during job interviews, social gatherings, or athletic events to meet the perceived norms of those environments.Contextual Adaptation and Social SignalsThe research...

The representative heuristic describes a biased way of thinking, in which you unintentionally stereotype someone or something. For example, you may assume that your professors spend their free time reading books and engaging in intellectual conversation, because the idea of them spending their time playing volleyball or visiting an amusement park does not fit in with your stereotypes of professors.

2.5K
Cognitive psychologist Richard Lazarus proposed the cognitive-mediational theory of emotions, which emphasizes how individuals' assessments of stressors significantly affect their experience of stress. According to Lazarus, the stress response is determined by a two-step appraisal process: primary appraisal and secondary appraisal. These cognitive appraisals help individuals evaluate the potential impact of a stressor and determine the adequacy of their coping resources.

According to some social psychologists, people tend to overemphasize internal factors as explanations—or attributions—for the behavior of other people. They tend to assume that the behavior of another person is a trait of that person, and to underestimate the power of the situation on the behavior of others. They tend to fail to recognize when the behavior of another is due to situational variables, and thus to the person’s state. This erroneous assumption is...
