چکیده انگلیسی مقاله |
This study aimed to evaluate the reliabilityfactors, and identify causes of error in direct anthropometry method. After trainingthree beginner anthropometrists and following the instructions of anthropometricstandards, 48 body dimensions of 42 male students were measured three times. Inother words, the physical dimensions of each subject were measured for 9 times.All participants were wearing uniforms during anthropometry, with bare feet.Differences in values of Repeated Measurement Test were explored using SPSSsoftware version 11. The same software was employed to evaluate, throughcalculating ICC index, the correlation between anthropometrists. Inter-observer repeated measurement test showedsignificant difference in the measurements taken in 3, 7 and 1 dimension(s) bythe three anthropometrists. The average measurement was significantly differentat 16 dimensions; this, however, showed no difference at 32 dimensions.Measurements taken by anthropometrist 1 had ICC values of 0.26 (Min.) and 0.99(Max.); these values were 0.48 (Min.) and 1.00 (Max.) for anthropometrist 2 and0.23 (Min.) and 0.98 (Max.) for antropometrist 3. The maximum and minimumvalues of ICC index in all three anthropometrists were respectively close toand above 0.98, and lower than 0.5. High value of ICC in the measureddimensions indicated high reliability of repeated measurements. The decreasingvalue of some indexes can be attributed to such factors as random error, poordesign of measurements tool (which in turn leads to random error), the longtime devoted to measurement process, high number of dimension measured, changesin posture of subjects and deviation from the standard position. |
