The Social Norms Questionnaire–Dutch version (SNQ-NL) measures the ability to understand and identify social boundaries. We examined the psychometric characteristics of the SNQ-NL and its ability to differentiate between patients with behavioral variant frontotemporal dementia (bvFTD; n = 23), Alzheimer’s dementia (AD; n = 26), chronic psychiatric disorders (n = 27), and control participants (n = 92). Between-group differences in the Total score, Break errors, and Overadhere errors were examined and associations with demographic variables and other cognitive functions were explored. Results showed that the SNQ-NL Total Score and Break errors differed between patients with AD and bvFTD, but not between patients with bvFTD and psychiatric disorders. Modest correlations with age, sex, and education were observed. The SNQ-NL Total score and Break errors correlated significantly with emotion recognition and verbal fluency but not with processing speed or mental flexibility. In conclusion, the SNQ-NL has sufficient construct validity and can be used to investigate knowledge of social norms in clinical populations.

社会规范问卷 - 荷兰语版本 (SNQ-NL) 衡量理解和识别社会边界的能力。我们检查了 SNQ-NL 的心理测量学特征及其区分行为变异性额颞叶痴呆（bvFTD；n = 23）、阿尔茨海默病痴呆（AD；n = 26）、慢性精神疾病（n = 27）和控制参与者（n= 92)。检查了总分、中断错误和过度坚持错误的组间差异，并探讨了与人口统计变量和其他认知功能的关联。结果显示，AD 和 bvFTD 患者的 SNQ-NL 总分和中断误差存在差异，但 bvFTD 和精神疾病患者之间没有差异。观察到与年龄、性别和教育程度的适度相关。SNQ-NL 总分和中断错误与情绪识别和语言流畅度显着相关，但与处理速度或心理灵活性无关。总之，SNQ-NL 具有足够的结构效度，可用于调查临床人群的社会规范知识。
