The aim of this study was to extend the psychometric evaluation of the Short Self-Regulation Questionnaire (SSRQ) by assessing the factor structure across three countries from Central and Eastern Europe. The sample included 1809 students from Slovakia, Lithuania and Hungary. Based on an initial confirmative factor analysis, a 2-factor structure by Neal and Carey (2005) was confirmed in the Lithuanian sample. Next, exploratory factor analyses were used on the Slovak and Hungarian subsamples separately. For both national subsamples, a very similar four factor solution was found, which was confirmed by confirmatory factor analyses on the rest of the data. Despite the reduced number of items, the abridged scale did not suffer in terms of its internal reliability and thus provides an adequate approximation of self-regulation levels as the entire scale or as the scale with the proposed 4-factor solution.

三个欧洲国家简短自我调节问卷的心理测量评估

本研究的目的是通过评估来自中欧和东欧的三个国家的因素结构来扩展简短自我调节问卷 (SSRQ) 的心理测量评估。样本包括来自斯洛伐克、立陶宛和匈牙利的 1809 名学生。根据最初的验证性因子分析，Neal 和 Carey (2005) 在立陶宛样本中证实了 2 因子结构。接下来，分别对斯洛伐克和匈牙利子样本使用探索性因素分析。对于这两个国家子样本，发现了非常相似的四因素解决方案，这通过对其余数据的验证性因素分析得到证实。尽管物品数量减少，
