Image-based sexting constitutes a visual form of sexual communication. Yet, the degree to which satisfaction with one's physical appearance emboldens or inhibits young adults from engaging in sexting behaviors is poorly understood. This study investigated whether body esteem related to specific body parts and functions could uniquely predict sending sexts, sending consensual but unwanted sexts, and decisions against sending sexts. Six hundred and fourteen Australians aged 18–21 years (M = 19.57, SD = 1.15) took part in the study. Binomial regressions revealed that negative body esteem in relation to lips made a unique contribution to the higher likelihood of sending sexts for women. No further individual body parts or functions made a unique contribution to the models for sending sexts, sending consensual but unwanted sexts, or decisions against sexting across genders. However, body image esteem in relation 35 body parts and functions collectively explained 23% and 35% of variance in sending sexts for women and men. It also explained 14% and 28% of variance in decisions against sending sexts for women and men respectively, but made no significant contribution to the prediction of consensual but unwanted sexts across genders. Methodological implications and directions for future research are discussed.

基于图像的色情短信构成了性交流的一种视觉形式。然而，对一个人的外表的满意程度会在多大程度上鼓励或抑制年轻人从事色情短信行为，我们知之甚少。这项研究调查了与特定身体部位和功能相关的身体自尊是否可以唯一地预测发送性短信、发送双方同意但不受欢迎的短信以及反对发送短信的决定。614 名 18-21 岁的澳大利亚人 ( M  = 19.57, SD = 1.15) 参与了研究。二项式回归表明，与嘴唇相关的负面身体自尊对女性发送性短信的可能性更高做出了独特的贡献。没有进一步的个人身体部位或功能对发送性短信、发送双方同意但不受欢迎的短信或反对跨性别发送短信的模型做出独特贡献。然而，与 35 个身体部位和功能相关的身体形象尊重共同解释了发送女性和男性性短信的 23% 和 35% 的差异。它还解释了在反对为女性和男性发送性短信的决定中分别有 14% 和 28% 的差异，但对预测跨性别双方同意但不受欢迎的性短信没有显着贡献。讨论了未来研究的方法学意义和方向。
