Summary
The Fear of COVID-19 Scale (FCV-19S) demonstrates consistent reliability, with pooled estimates ranging from .85 to .90. A predictive model identified score variability as a key factor influencing reliability coefficients.
Area of Science:
- Psychometrics
- Psychological Measurement
- Health Psychology
Background:
- The COVID-19 pandemic spurred the development of numerous psychological scales.
- The Fear of COVID-19 Scale (FCV-19S) is a widely adopted measure.
- Assessing the reliability of such scales is crucial for valid interpretation.
Purpose of the Study:
- To conduct a reliability generalization meta-analysis of the FCV-19S.
- To estimate the average reliability of the FCV-19S across diverse samples.
- To identify moderators influencing reliability and propose a predictive model.
Main Methods:
- Meta-analysis of reliability coefficients (Cronbach's alpha, Rasch model) from 42 studies (44 independent samples).
- Examination of heterogeneity using moderator analyses.
- Development of a predictive model for FCV-19S reliability.
Main Results:
- Pooled reliability estimates for the FCV-19S ranged from .85 to .90.
- Cronbach's alpha was the most frequently reported reliability coefficient.
- The standard deviation of scores explained 36.7% of the variability in alpha coefficients.
Conclusions:
- The FCV-19S exhibits consistently high reliability across various contexts.
- The scale's reliability is robust and not significantly affected by the examined moderator variables.
- A predictive model enhances understanding of factors influencing FCV-19S reliability.

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...

01:29Reliability and Validity
13.4K
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.

01:09Preparedness and Phobias
220
Human fear responses to certain stimuli, such as darkness, heights, deep water, and blood, can often arise despite the absence of direct negative experiences. This phenomenon is rooted in evolutionary psychology, which posits that humans have developed a predisposition to fear stimuli that historically posed significant survival threats. This predisposition, known as preparedness, suggests that early humans who developed a fear of potentially dangerous entities, such as venomous snakes and...

Relative risk (RR) is a statistical measure commonly used in epidemiology to compare the likelihood of a particular event occurring between two groups. This metric is important for evaluating the relationship between exposure to a specific risk factor and the probability of a particular outcome. It plays a crucial role in medical research, public health studies, and risk assessment. Relative risk quantifies how much more (or less) likely an event is to occur in an exposed group compared to an...

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.

The confidence coefficient is also known as the confidence level or degree of confidence. It is the percent expression for the probability, 1-α, that the confidence interval contains the true population parameter assuming that the confidence interval is obtained after sufficient unbiased sampling; for example, if the CL = 90%, then in 90 out of 100 samples the interval estimate will enclose the true population parameter. Here α is the area under the curve, distributed equally under...
