Uji Validitas dan Reliabilitas Alat Ukur SG Posture Evaluation

Abstract

Abstract. Validity Test, Reliability Test, Measuring Instrument, SG Posture Evaluation. The SG Posture Evaluation gauge is designed and created to measure changes in posture in adults and children. the level of validity and reliability of measuring instruments SG Posture Evaluation is very necessary with the aim that can be known the level of validity and reliability of these measuring devices so that they can bind the benefits as scientific references and can be used in the community. The number of samples was 84, there were 10 statements / assessment items, 5 parallel to the spine and 5 items from the side of the neck (neck, shoulder, thorax, lumbar and pelvic), the data were tested with Pearson and Cronbach's aplha. Posture assessment results from balakang obtained: (1) Neck 170; (2) Shoulder 323 **; (3) Thorax 128; (4) Lumbar a / 0; (5) Pelvic 260 *. spinal posture assessment items seen from the side obtained: (1) Neck 747 **; (2) Shoulder 276 *; (3) Thoraks 301 **; (4) Lumbar 489 **; (5) Pelvic 334 **. Item values ​​with a ** sign have a significant correlation at the 0.01 level. Value items with a sign *. There is a significant correlation at the 0.05 level. The level of reliability with an alpha cronback value of 612 values ​​greater than 0.6. so the reliability level is very good. The conclusion is that the validity of the SG Posture Evaluation 4 measuring instrument is parallel to the spine (neck, shoulder, thorax, and pelvic) and 4 items from the side of the neck, shoulder, thorax, and pelvic). There is a reliability level of the SG Posture Evaluation gauge.
