Summary
A new Surgical Anxiety Questionnaire (SAQ) was developed to measure preoperative anxiety. The SAQ demonstrates good reliability and validity, showing promise for assessing patient concerns and predicting surgical recovery.
Area of Science:
- Psychology
- Medical Sociology
- Health Psychology
Background:
- Preoperative anxiety assessment often relies on general measures, which may lack specificity or psychometric validation.
- Existing tools for surgery-specific anxiety may have limited content coverage or insufficient validation.
Purpose of the Study:
- To develop a novel self-report measure for surgery-specific anxiety.
- To rigorously test the psychometric properties of this new measure.
Main Methods:
- The Surgical Anxiety Questionnaire (SAQ) was created based on qualitative research themes and expert review.
- Administered preoperatively to 135 surgical patients, alongside other anxiety and stress measures.
- Follow-up assessments post-surgery and at two weeks evaluated recovery and predictive validity.
Main Results:
- Factor analysis identified a three-component structure: concerns about health, recovery, and procedures (17 items total).
- The SAQ exhibited good reliability and content, construct, and predictive validity.
- Overall psychometric properties were deemed adequate.
Conclusions:
- The SAQ appears to be a valuable tool for measuring preoperative anxiety.
- It shows potential for predicting patient recovery following surgery.
- Future research should include confirmatory factor analysis and test-retest reliability studies.

01:18Anxiety: Overview
1.0K
Anxiety is a common mental disorder featuring excessive worry, fear, and apprehension, significantly affecting daily life. People with anxiety disorders experience persistent and intense anxiety, interrupting their everyday functioning.
Individuals with anxiety often experience a range of physical and emotional symptoms, including sweating, trembling, tachycardia, and disturbances in sleep patterns. These symptoms vary in intensity and frequency but are generally disruptive and distressing.

01:29Reliability and Validity
13.9K
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.

In vitro dissolution and drug release tests assess how quickly and how much of a drug is released from its dosage form into an aqueous medium under standardized laboratory conditions. These tests are essential tools in pharmaceutical development and quality assurance, offering insight into the drug's performance before clinical use.During formulation development, dissolution testing identifies incomplete or inconsistent drug release issues. It also supports decisions on selecting the optimal...

Generalized Anxiety Disorder (GAD) is a chronic condition characterized by excessive and uncontrollable worry that persists for at least six months, significantly interfering with daily functioning. Unlike situational anxiety, which arises in response to specific stressors, GAD often occurs without a clear cause. Individuals may experience disproportionate worry about work, health, or relationships. For instance, a person might continuously fear poor health despite normal medical evaluations or...

Social anxiety disorder, also known as social phobia, is characterized by an intense fear of social situations where one might face humiliation, rejection, embarrassment, or negative evaluation. This disorder leads individuals to avoid activities like casual conversations, public speaking, or seemingly simple tasks such as eating, signing documents, or swimming, in public settings. Its impact extends beyond discomfort, often significantly interfering with daily functioning and quality of life.

Method validation is a crucial process in analytical chemistry designed to confirm that a given method consistently produces reliable and high-quality results. This process is essential when a method is applied to different sample matrices or when procedural modifications are made, ensuring that the results meet acceptable standards across various applications.
