This study aims to analyze the effects of ideal and actual self-congruence and functional congruence on the volunteering intentions of university students. The empirical analysis is based on a sample of 735 students from universities in southwestern Germany. The current paper shows that stereotypic image perceptions (i.e., perceived warmth and competence) represent antecedents of the considered congruence constructs. Moreover, the study shows that actual self-congruence and functional congruence mediate the effect of perceived warmth and competence on the intention to volunteer. Ideal self-congruence did not mediate the effect of stereotypical image perceptions, nor did it have a direct effect on the willingness to take voluntary action. The study offers practical recommendations for nonprofit organizations, as well as avenues for future research based on its empirical findings.

本研究旨在分析理想的和实际的自我一致性以及功能一致性对大学生志愿服务意愿的影响。实证分析基于来自德国西南部大学的735名学生的样本。当前的论文表明，刻板印象的图像感知（即感知的温暖和能力）代表了所考虑的一致性构造的先决条件。此外，研究表明，实际的自我一致性和功能一致性会介导感知到的温暖和能力对志愿人员意愿的影响。理想的自我一致性不会调解刻板印象的观念，也不会对采取自愿行动的意愿产生直接影响。该研究为非营利组织提供了实用建议，
