ABSTRACT

Sex-related cannabis expectancies have been found to be associated with intentions to use cannabis, cannabis use, and sexual behavior. However, the construct of sex-related cannabis expectancies has been adapted from research with limited examination of the scales themselves. We tested (N = 350 adolescents age 13–17; N = 929 young adults age 18–29) measurement invariance of a sex-related cannabis expectancies scale and found the scale invariant between adolescents and emerging adults as well as between genders. But the partial invariance across age groups suggested that one item from the scale contained systematic errors in assessing the age group differences and warrants additional examination. Latent mean difference tests revealed that young people’s sex-related cannabis expectancies differ between age groups and genders.

摘要

已发现与性相关的大麻预期与使用大麻的意图、大麻使用和性行为有关。然而，与性相关的大麻预期的构建已经根据对量表本身进行有限检查的研究进行了调整。我们测试了（N = 350 名 13-17 岁的青少年；N = 929 名 18-29 岁的年轻人）与性别相关的大麻预期量表的测量不变性，发现该量表在青少年和新兴成年人之间以及性别之间是不变的。但跨年龄组的部分不变性表明，量表中的一项在评估年龄组差异时存在系统误差，需要进一步检查。潜在平均差异测试显示，年轻人对性相关的大麻预期因年龄组和性别而异。
