NMSK II Pediatric Outcome Measures Practice Test

Question 1

Which scenario best describes intra-rater reliability?

The same rater scores the same performance on two occasions. Two different raters score the same performance. A test yields the same result on different days with no change. A measure correlates with another measure.

Correct Answer:

The same rater scores the same performance on two occasions.

Explanation:

Intra-rater reliability is about one person rating or scoring the same performance consistently across multiple occasions. If the same rater evaluates the same performance on two different days and the scores are essentially the same, it shows that the rater is stable and dependable over time, minimizing scoring drift or bias. Think of it as the score reflecting the performer, not the rater changing their mind. In contrast, having two different raters score the same performance tests inter-rater reliability, where agreement between raters is examined. When a test gives the same result across different days regardless of who uses it, that’s about test-retest reliability—the stability of the measure over time, not the consistency of a single rater. And if a measure relates to another measure, that’s about validity, not reliability.

Question 2

PEDI-CAT can be administered by which combination?

Clinicians Only Clinicians, Educators, or Parent Report Parents Only Researchers Only

Correct Answer:

Clinicians, Educators, or Parent Report

Explanation:

PEDI-CAT is designed to capture a child’s functional abilities across daily activities by collecting information from the person most familiar with how the child functions in each setting. It can be administered by clinicians in a clinical or research context, by educators who observe the child in school, or by parents/caregivers who report on home life. This flexibility lets the instrument reflect performance across multiple environments and perspectives, giving a more complete picture of the child’s abilities and needs. It’s not limited to a single reporter type, which is why the option describing clinician, educator, or parent report is the best choice.

Question 3

Which statement best describes the difference in output between GMFM-66 and GMFM-88?

GMFM-66 yields a single interval score via Rasch analysis. GMFM-66 yields a single interval score via Rasch analysis, while GMFM-88 provides separate dimension scores and a total percent score from 88 items. GMFM-66 uses a fixed total percent score from 66 items. GMFM-66 is designed for infants and GMFM-88 for adolescents.

Correct Answer:

GMFM-66 yields a single interval score via Rasch analysis, while GMFM-88 provides separate dimension scores and a total percent score from 88 items.

Explanation:

Rasch analysis is used to place responses on a single, linear scale, turning observed performance into an interval measurement of gross motor function. The GMFM-66 uses 66 items that fit this unidimensional Rasch model, so it yields one overall interval score that represents the child’s gross motor ability on a continuous scale. In contrast, the GMFM-88 includes all 88 items arranged into five functional dimensions and provides scores for each dimension plus a total percentage score across all items. That means its outputs are multi-dimensional rather than a single interval estimate. So the difference in output is that the GMFM-66 yields a single interval score, while the GMFM-88 provides separate dimension scores and a total percent score from 88 items.

Question 4

Which statement best describes PEDI-CAT in comparison to PEDI?

PEDI-CAT is fixed-item, PEDI is computer-adaptive. PEDI-CAT is computer-adaptive, using item response theory for scoring; PEDI is a traditional caregiver-reported measure with fixed items. PEDI-CAT is designed only for adults. PEDI-CAT and PEDI have identical scoring.

Correct Answer:

PEDI-CAT is computer-adaptive, using item response theory for scoring; PEDI is a traditional caregiver-reported measure with fixed items.

Explanation:

PEDI-CAT represents a shift to computer-adaptive testing that uses item response theory for scoring. As the respondent answers items, the system estimates their current level of function and selects subsequent questions that will provide the most information about that level. This tailoring often means fewer questions while keeping precision, and the scoring is driven by IRT estimates. In contrast, the traditional PEDI uses a fixed set of items that are the same for everyone and is typically caregiver-reported without adaptive item selection. It also relies on standard scoring of those fixed items rather than a model-based estimate of ability. The other statements don’t fit because PEDI-CAT is not fixed-item, it isn’t designed only for adults, and its scoring isn’t identical to PEDI.

Question 5

Who can administer the PEDI-CAT?

Clinicians Only Educators Only Clinicians, Educators, or Parent Report Patients Themselves Only

Correct Answer:

Clinicians, Educators, or Parent Report

Explanation:

The PEDI-CAT is designed to be completed by someone who knows the child well across different settings—clinicians, educators, or parents. This flexibility matters because the instrument aims to capture how a child functions in daily life, which requires input from those who observe the child in therapy, at school, and at home. Allowing multiple informants ensures the measure reflects a holistic view of the child’s abilities, not just what one person sees in one setting. Relying on the child themselves isn’t always feasible or reliable for all ages or communication abilities, and limiting administration to only clinicians or only educators would miss important perspectives from family life or school environments.
