Abstract
Introduction: The most prevalent malnutrition problem in Indonesia among young children is low height for age. Height or length of the young is known to be difficult to measure. This study was aimed at developing an instrument called Pengukur Panjang Badan Bayi Digital (P2B2D) Version 1.0 based on the main consideration of WHO recommendations on accuracy and precision of length measurements. Methods: Design of the study included instrument development, and reliability and validity tests on the instrument. This study involved 53 children aged below 2 years measured by three examiners using three different instruments namely, the P2B2D, wood length-board, and mica length-board. Results: The reliability coefficients of the P2B2D ranged from 0.747 (inter-method reliability against mica length-board using TEM analysis) to 0.966 (inter-method reliability against wood length-board using Pearson correlation analysis). The corresponding validity coefficients were 0.864 and 0.963, respectively. The only problem that emerged with the P2B2D was its weight, which was relatively heavy (6 kg). Conclusion: The reliability and validity of the P2B2D could be considered as substantial to excellent. It is recommended that this instrument be improved by minimising possible source of error and experimenting with different types of sensors.
