Nonformal adult education (NFE) provides adults with the opportunity to obtain competences needed to adapt to today’s changing job market. Despite the well-documented positive effects of NFE, there remains a lack of valid research instruments to assess factors of nonparticipation. Specifically, defining the perspectives of social groups with the highest incidence of barriers and the lowest level of participation in NFE has not been a primary research goal. This study describes the development and initial validation of a novel research tool entitled the Nonparticipation in Nonformal Education Questionnaire (NP-NFE-Q). The analysis covers the use of the NP-NFE-Q on a representative sample of the adult population (n = 878) as well as three additional cohorts: low-educated workers (n = 227), persons caring for children under the age of three (n = 227), and retired persons (n = 232). The results consistently support the validation of a correlated five-factor model, which includes two situational, one institutional and two dispositional factors.

非正规成人教育 (NFE) 为成年人提供了获得适应当今不断变化的就业市场所需能力的机会。尽管 NFE 的积极影响有据可查，但仍然缺乏有效的研究工具来评估不参与的因素。具体而言，定义障碍发生率最高且参与 NFE 水平最低的社会群体的观点并不是主要的研究目标。本研究描述了一种名为“不参与非正规教育问卷”（NP-NFE-Q）的新型研究工具的开发和初步验证。该分析涵盖了 NP-NFE-Q 对成年人口的代表性样本 ( n = 878) 以及另外三个群体的使用：受教育程度低的工人 ( n= 227)、照顾三岁以下儿童的人员 ( n = 227) 和退休人员 ( n = 232)。结果始终支持相关五因素模型的验证，该模型包括两个情境因素、一个制度因素和两个性格因素。
