OBJECTIVE: To investigate the psychometric properties of the Physical Abilities
and Mobility Scale (PAMS) in children receiving inpatient rehabilitation for
acquired brain injury (ABI). DESIGN: Admission and discharge PAMS item and total
scores were evaluated. The WeeFIM was used as the criterion standard. A case
study was used to illustrate the complementary nature of the PAMS and WeeFIM.
SETTING: A single, free-standing, academically affiliated pediatric
rehabilitation hospital. PARTICIPANTS: Children (N=107) aged 2 through 18 years
receiving inpatient rehabilitation for ABI between March 2009 and March 2012.
Forty-two additional children treated during this time were excluded because of
missing PAMS data. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Internal
consistency was evaluated using Cronbach alpha. Interrater reliability was
evaluated through overall agreement, Pearson correlations, and intraclass
correlations. Construct validity was examined through exploratory factor
analysis. Criterion validity was explored through correlations of PAMS overall
and factor scores with WeeFIM total and subscale scores. Sensitivity to recovery
was examined using paired t tests, examining differences between admission and
discharge scores for each item and for the total score. RESULTS: Internal
consistency and interrater reliability were high. Factor analysis revealed 2
factors: lower-level skills and higher-level mobility skills. Correlations with
the WeeFIM ranged from moderate to very strong; total PAMS score most strongly
correlated with the WeeFIM mobility subscore. Total PAMS score and each item
score significantly increased between admission and discharge. CONCLUSIONS: The
PAMS is a reliable and valid measure of progress during inpatient rehabilitation
for children with ABI. By capturing fine-grain progress toward both lower-level
and higher-level mobility skills, the PAMS complements the WeeFIM in assessing
functional gains during the rehabilitation stay.
