Summary
The Korean version of the Startle, Physiological arousal, Anger, and Numbness (SPAN-K) scale demonstrates strong reliability and validity for screening post-traumatic stress disorder (PTSD). This validated tool aids in the rapid identification of PTSD in clinical settings.
Area of Science:
- Psychiatry
- Psychometrics
Background:
- Post-traumatic stress disorder (PTSD) requires effective screening tools.
- The Startle, Physiological arousal, Anger, and Numbness (SPAN) scale is a brief PTSD screening measure.
Purpose of the Study:
- To develop and validate a Korean version of the SPAN scale (SPAN-K).
- To assess the psychometric properties of the SPAN-K for PTSD screening.
Main Methods:
- Recruited 93 PTSD patients, 73 psychiatric controls, and 88 healthy controls.
- Administered SPAN-K alongside established measures like CAPS and DTS.
- Evaluated reliability, concurrent validity, and diagnostic accuracy using ROC analysis.
Main Results:
- SPAN-K showed excellent test-retest reliability (0.80) and internal consistency (Cronbach's α=0.80).
- High correlations were found between SPAN-K and CAPS (0.87) and DTS (0.86) scores.
- Receiver operating characteristic analysis indicated good diagnostic accuracy (AUC=0.87) with optimal cutoff at 7 (sensitivity 0.83, specificity 0.81).
Conclusions:
- The SPAN-K exhibits robust psychometric properties.
- The SPAN-K is a reliable and valid instrument for rapid PTSD screening in Korean populations.

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.
01:20Kendall's Coefficient of Concordance
Kendall's Coefficient of Concordance (W), also known as Kendall's W, is a non-parametric statistical measure used to assess the agreement or concordance between multiple raters or judges when they rank a set of items. It is often used when you have ordinal data (ranks) and you want to see if there is consistency or consensus among the raters. It is widely applied in research areas such as psychology, medicine, and social sciences, where multiple judges are asked to rank or rate subjects or...
01:03Data Validation
Data validation is an essential part of a comprehensive assessment. Validation is confirming or verifying and opening the door to gathering more assessment data as it clarifies vague or unclear data. The process of checking and verifying the collected information is called data validation. The primary purpose of data validation is to ensure data is as free from error, bias, and misinterpretation as possible.

01:15Data Validation
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.
Key parameters for method validation include:

01:16Goodness-of-Fit Test
The goodness-of-fit test is a type of hypothesis test which determines whether the data "fits" a particular distribution. For example, one may suspect that some anonymous data may fit a binomial distribution. A chi-square test (meaning the distribution for the hypothesis test is chi-square) can be used to determine if there is a fit. The null and alternative hypotheses may be written in sentences or stated as equations or inequalities. The test statistic for a goodness-of-fit test is given as...
01:22Statistical Package for the Social Sciences (SPSS)
The Statistical Package for the Social Sciences, or SPSS, is a data management and analysis software suite. Developed by SPSS Inc. in 1968 and acquired by IBM in 2009, this tool was initially designed for social science data analysis, evolving to serve a wider range of disciplines. It was later renamed to Statistical Product and Service Solutions.
