Ammons quick test validity among randomly selected referrals
Psychological Reports
|April 4, 2014
Summary
The Ammons Quick Test (QT) remains a valid measure of receptive vocabulary and verbal intelligence after 51 years. Its scores correlate well with other cognitive and adaptive behavior assessments for youth and adults.
Area of Science:
- Psychometrics and Educational Psychology
- Neuropsychology and Cognitive Assessment
Background:
- The Ammons Quick Test (QT) has been in use for over five decades.
- Its continued validity and utility in contemporary clinical settings require ongoing evaluation.
- Assessing receptive vocabulary, verbal intelligence, and auditory processing remains crucial in developmental and clinical psychology.
Purpose of the Study:
- To evaluate the psychometric properties and clinical utility of the Ammons Quick Test (QT).
- To determine the correlation of the Ammons QT with other established cognitive and adaptive behavior measures.
- To ascertain the continued validity of the original Ammons QT norms after 51 years.
Main Methods:
- A sample of 89 Youth and 147 Adults were recruited via volunteer referrals and selected using a random number table.
- Participants completed the Ammons Quick Test (QT).
- Pearson product-moment correlations were computed between the Ammons QT and the Peabody Picture Vocabulary Test-3b (PPVT-3b), Vineland Adaptive Behavior Scales-2, Wechsler Intelligence Scales (WISC-4/WAIS-4), and Wide Range Achievement Test-Fourth Edition (WRAT-4).
Main Results:
- The Ammons Quick Test (QT) demonstrated moderate to strong and statistically significant correlations with the PPVT-3b, Vineland Adaptive Behavior Scales-2, WISC-4/WAIS-4, and WRAT-4.
- These correlations indicate that the Ammons QT effectively measures constructs similar to those assessed by these other standardized instruments.
- The statistical analyses support the continued relevance of the Ammons QT's original norms.
Conclusions:
- The Ammons Quick Test (QT) remains a valid and reliable measure for assessing receptive vocabulary, verbal intelligence, and auditory information processing in both youth and adult populations.
- Its strong correlations with other widely used assessments suggest its continued utility for clinicians.
- The original norms established 51 years ago are still applicable for current clinical evaluations.

Cochran's Q Test is a nonparametric statistical test used to determine if there are potential differences in the outcomes of three or more related groups on a binary (yes/no) or dichotomous outcome. It is essentially an extension of the McNemar Test, which is limited to two related samples - Cochran's Q test can handle three or more related samples, making it more versatile in scenarios where subjects are measured under multiple conditions. The test statistic follows a Chi-Square...

1.0K
McNemar's Test is a nonparametric statistical test used to determine if there is a significant difference in proportions between two related groups when the outcome is binary (e.g., yes/no, success/failure). It is beneficial when we have paired data, such as pre-test/post-test designs, where the same subjects are measured under two different conditions. The test is named after the statistician Quinn McNemar, who introduced it in 1947. It is commonly used in situations where subjects are...

The Bonferroni test is a statistical test named after Carlo Emilio Bonferroni, an Italian mathematician best known for Bonferroni inequalities. This statistical test is a type of multiple comparison test to determine which means are different than the rest. Bonferroni test can minimize the Type 1 error by reducing the significance level alpha, which otherwise increases with sample pairs.

595
Friedman's Two-Way Analysis of Variance by Ranks is a nonparametric test designed to identify differences across multiple test attempts when traditional assumptions of normality and equal variances do not apply. Unlike conventional ANOVA, which requires normally distributed data with equal variances, Friedman's test is ideal for ordinal or non-normally distributed data, making it particularly useful for analyzing dependent samples, such as matched subjects over time or repeated measures...

01:29Reliability and Validity
12.9K
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.

01:17Sign Test for Matched Pairs

The sign test for matched pairs offers a robust method for comparing two paired samples, often for the effects of an intervention in one of them. This method is very useful in situations where the underlying distribution of the data is unknown. The test compares two related samples—often pre- and post-treatment measurements on the same subjects—to determine if there are significant differences in their median values.
