🔎From Data to Diagnosis in SSDs
Making an accurate diagnosis is more than just standardized testing. Assessment tools like the AAPS and GFTA give you a 📸 snapshot of phonetic accuracy across sounds and positions. However making a differential diagnosis means piecing together the whole 🧩puzzle, not just counting errors.
Helpful Reminders:
👉🏻Be sure to collect a connected speech sample. Listen for consistency, patterns, and prosody. Are errors the same every time or do they change word to word? Are errors rule-based or random?
👉🏻Check stimulability. Can the child imitate the sound when you model it? If yes, it’s likely a phonological issue. If no, it may be a motor (CAS or articulation)issue.
👉🏻Look at error patterns. Fronting, stopping, and cluster reduction (among others) imply a rule-based error or a phonological delay/disorder.
👉🏻Distorted but consistent single sound errors may indicate an articulation disorder.
👉🏻Inconsistent productions can be indicative of an inconsistent speech disorder.
👉🏻Difficulty sequencing sounds, groping, and vowel errors are hallmarks of childhood apraxia of speech.
👉🏻Complete a dynamic assessment. What does speech sound like in words that vary in syllable structure, number of syllables, and varying stress patterns.
Diagnosis is critical to providing the appropriate treatment/intervention in speech sound disorders therapy. Take your time and do the 🕵🏻♀️detective work!
