The factor structure of Japanese adults' body build stereotypes was assessed through having 90 male and 90 female university students attribute 56 verbal checklist items to stimulus pictures of a male Endomorph, Mesomorph, and Endomorph, respectively. The attitudinal factor structure of the two sex groups was markedly similar, and with both groups a positive Mesomorph factor and negative Endomorph and Endomorph factors were found. These Japanese adult factor structures were compared to corresponding data obtained with adolescent Japanese males and females, and with American adolescent and adult males. In addition to similar evaluative valences being associated with corresponding body build factors among all cultural groups, intercultural continuity was evidenced by markedly high inter- (as well as intra-) cultural factor congruence coefficients.
