Which Outcome Measures (OMs) are exclusively Norm referenced?

The correct selection encompasses the outcome measures used in pediatric assessments that are strictly norm-referenced. Norm-referenced tests compare an individual's performance to that of a normative sample, allowing for the determination of how a child's abilities stack up against their peers.

The Test of Infant Motor Performance (TIMP), the Alberta Infant Motor Scale (AIMS), and the Bruininks-Oseretsky Test of Motor Proficiency (BOT2) are all designed to measure and compare performance across a defined population. Their scoring is based on norms established from a representative sample, which helps identify developmental delays or challenges in motor skills as compared to typical development trajectories.

In contrast, the other options mentioned contain outcome measures that utilize a criterion-referenced approach or a combination of norm-referenced and criterion-referenced measures. For instance, the Gross Motor Function Measure (GMFM) evaluates a child's motor function in relation to set criteria rather than comparing them to a normative group. Similarly, the Sensory Profile Assessment (SFA) and other measures in the alternatives assess specific skills or criteria relevant to performance rather than normative comparisons exclusively.

Thus, the trio of measures in the selected outcome is definitively reliant on norms for interpretation and comparison, making it the most accurate collection reflecting exclusively norm-re
