The Body Caliper is a relatively new model of skin–fold caliper (approximately 13 years old) whose reliability and validity has yet to be investigated on an adult population. Therefore, the purpose of this study was to investigate the reliability and validity of the Body Caliper as an instrument and method for evaluating body composition in adults. One hundred adults (62 men, 38 women) aged 18 to 60 years participated in this cross–sectional study. Skin–fold measurements were taken with the Body Caliper using the YMCA protocol, and body density was calculated by the Jackson & Pollock sum–of–3 equations for men and women. Hydrostatic weighing served as the criterion method that the Body Caliper was compared to for validation. The reliability of the Body Caliper was assessed by an intraclass correlation coefficient and was proven reliable (ICC= .997). The validity of the Body Caliper was assessed by Bland-Altman analysis and was proven valid by 96% of the sample reaching agreement between the two methods. The results of this study have demonstrated the Body Caliper to be a reliable and valid instrument and method for evaluating body composition.
