Four studies (total n = 961) developed and validated the Adolescent Conspiracy Beliefs Questionnaire (ACBQ). Initial items were developed in collaboration with teachers. An exploratory factor analysis (Study 1, n = 208, aged 11–14) and a student focus group (N = 3, aged 11) enabled us to establish the factor structure of a 9-item scale. This was replicated via confirmatory factor analysis in Study 2 (N = 178, aged 11–17), and the scale displayed good convergent (i.e., relationship with paranoia and mistrust) and discriminant validity (i.e., no relationship with extraversion). Study 3a (N = 257) further tested convergent validity with a sample of 18-year-olds (i.e., relationship with adult-validated measures of conspiracy beliefs) and demonstrated strong test–retest reliability. Study 3b (N = 318) replicated these findings with a mixed-age adult sample. The ACBQ will allow researchers to explore the psychological antecedents and consequences of conspiracy thinking in young populations.

衡量青少年对阴谋论的信念：青少年阴谋信念问卷 (ACBQ) 的制定和验证

四项研究（总共n  = 961）制定并验证了青少年阴谋信念问卷 (ACBQ)。最初的项目是与教师合作开发的。探索性因子分析（研究 1，n  = 208，11-14 岁）和学生焦点小组（N  = 3，11 岁）使我们能够建立 9 项量表的因子结构。这在研究 2（N  = 178，11-17 岁）中通过验证性因素分析得到复制，该量表显示出良好的收敛性（即，与偏执和不信任的关系）和区分效度（即，与外向性无关）。研究 3a ( N = 257) 进一步测试了 18 岁样本的收敛效度（即与成年人验证的阴谋信念测量的关系），并证明了很强的重测信度。研究 3b ( N  = 318) 用混合年龄的成人样本重复了这些发现。ACBQ 将使研究人员能够探索年轻人群体中阴谋思维的心理前因和后果。
