People’s accents in speech strongly influence how they are perceived by others. The current Accent Beliefs Scale was inspired by work on stigmatization, implicit theories of intelligence, and essentialism. The scale has two dimensions: accent diagnosticity and accent stability. The scale was developed, validated, and applied using a mixed methods approach with a QUAN–qual sequential design. Pretest and Study 1 developed the items, the subscales, and showed that diagnosticity and stability beliefs are independent of each other. Study 2 confirmed the scale’s two-factor structure on a large sample and proved its divergent and convergent validity. Study 3 addressed predictive validity and showed that the more perceivers viewed accents as diagnostic of other traits and the more they believed accents can be changed, the worse they evaluated a nonnative speaker with a strong accent. The developed scale can help understanding and predicting negative reactions to nonnative speakers.

口音信念量表 (ABS)：量表开发和验证

人们在讲话中的口音强烈影响他人对他们的看法。当前的口音信念量表的灵感来自污名化、智力的内隐理论和本质主义。该量表有两个维度：口音诊断和口音稳定性。该量表是使用具有 QUAN 质量序列设计的混合方法开发、验证和应用的。预测试和研究 1 开发了项目、分量表，并表明诊断性和稳定性信念是相互独立的。研究 2 在大样本上证实了该量表的双因子结构，并证明了其发散效度和收敛效度。研究 3 解决了预测有效性，并表明越多的感知者将口音视为其他特征的诊断，他们就越相信口音可以改变，他们对带有浓重口音的非母语人士的评价越差。开发的量表可以帮助理解和预测对非母语人士的负面反应。
