Abstract
Aim: To investigate the validity and reliability of the Portuguese version of the Test of Infant Motor Performance (TIMP) for Brazilian infants.Methods: The study was conducted with 20 health professionals and 655 Brazilian infants (between 34 weeks of Post-Menstrual Age and 17 weeks Corrected Age).Results: (1) Content validity: High concordance among the experts, for language clarity and pertinence, were found (ICC from.74 to .100; AC1 from .87 to 1.00); (2) Inter-rater, intra-rater, and test-retest reliability: Strong inter (α from .65 to .99) and intra (α from .97 to .99) raters agreement, and high test-retest reliability (r = 1.00; ICC = 1.00); (3) Internal consistency: Excellent internal consistency (α from .71 to .98); (4) Discriminant validity: Significant power to identify groups at-risk for delays (p < .0001); (5) Predictive validity: Capability to predict motor delay (r .55 to .89) was found; and, (6) Concurrent validity: Significant (p < .05) and low correlations at the first months (τ .21 to .24) and weak to moderate correlations at 3 and 4 month-old (τ .42 and .44, respectively) were observed between the TIMP and Alberta Infant Motor Scale.Conclusions: The results provide evidence of validity and reliability of the Portuguese version of the TIMP for Brazilian infants.
