Transcript of Goldman Fristoe-2
Test of Articulation Sounds In Words Section This part uses...
34 picture plates
53 target words to elicit articulation
of 61 consonants Sounds in Sentences Section Provides a semi-structured observation of the examinee's ability to produce spontaneous speech and retell one to two picture based stories that the examiner previously read aloud. The primary purpose: Provide a SLP with a method to
assess an individual's articulation
of consonant sounds. A basic description Assesses the articulation of
consonants in Standard American English.
It samples both spontaneous and imitative speech production by dividing the test into 3 sections to obtain descriptive information:
Sounds in Words, Sounds in Sentences, and Stimulability 16 consonant clusters in the initial
position Stimulability Section In this section, the examiner will model a previously misarticulated sound produced by the examinee in the previous sections. After the sound is modeled, the examinee will produce that sound. Sample of the Sounds in Words section Is it hard to administer? The Goldman Fristoe-2 is relatively easy to administer. Each section of GFTA-2 comes with instructions. It is advised to read through the manual, and then within the easel there are quick instructions that are easy to follow. As long as the examiner reads these instructions before administering the test, there should be little to no confusion on how to use it. Did I find it reliable? Based on the data presented in the manual, the reliability of this assessment is good and has high test-retest reliability, internal consistency, and interrater reliability. Its wide usage since the 1960s speaks volumes for how useful this assessment is in the field of Speech-Language Pathology The Norms of the GFTA-2 The Goldman Fristoe started as a Criterion-Referenced Test only.
Its purpose is to compare an examinee's performance to the correct consonant sounds. This is the information that helps in therapy planning.
HOWEVER, Normative information was added beginning in 1972 because funding sources demanded the norm-referenced comparisons to justify the need for someone to receive services. Thus, the GFTA-2 is both a criterion referenced test and a norm referenced test. What about its Validity? content validity: 23 of the 25 consonants are present in the GFTA-2.
construct validity: evidence that sounds-in-words measures articulation is found in Developmental progression of raw scores GFTA-2 Facts The GFTA-2 is the second edition It was published in 2000 Age Range: 2-21 years It is the latest edition There is no reading required of the examinee
Its sole target is the English speaking population
It was last revised in 1999, and published in 2000. As it is now 2013, the subject matter and pictures could be updated to include more current material. The Instructions Weaknesses Takes 5-15 minutes to administer How are the scores reported/interpreted? The Report form allows you to compare the findings of each section side by side simultaneously.
It is colored coded to represent initial, medial, and final word position.
Below, is the report form. More on Interpretation Interpretation is based on the assumption that the criterion for comparison for each sound is correct.
Knowing which sound the examinee produces incorrectly and in what position is more useful in planning therapy then using quantitive scores to compare the examinee to other individuals.
Normative scores are available for the sounds in words section if needed by funding sources, research, or for supplemental diagnostic interpretation Standardization of Norms Standardization was completed in 1999.
2,350 examinees between the ages of 2-0 and 21-11, were tested at 300 sites nationwide Normative information was based off:
mother's education level
age The standardization of norms is only available for the Sounds-In-Words section of the GFTA. Aged based scores are available. The number of errors can be converted to standard scores.
Aged based standard scores have a mean of 100 and a standard deviation of 15. This is also the only section that contains normative scoring Scores Available: Test-Age Equivalents, Percentiles, and Aged-Based Standard Score The test can be score by hand or through Scoring Assist (Computer)
