Individuals who choose to be childfree often face misunderstanding and a lack of acceptance from others. In many cases, this results in negative attitudes, followed by discrimination and prejudice. There have been few studies that would allow us to determine which features are responsible for treating childfree individuals with prejudice. This study aimed to explore the effect of five possible features that could influence others' prejudice towards childfree individuals: collective narcissism, right-wing authoritarianism, religiosity, political beliefs, and generativity. The study was conducted in Poland among 229 participants (age 19–59, M = 30.23; SD = 6.72). Commonality analysis was performed which allowed us to isolate both unique and common effects of possible predictors on the dependent variable (prejudice). Right-wing authoritarianism, political beliefs, and collective narcissism had both a unique and common effect on the dependent variable. Religiosity only had a common effect on prejudice, whereas generativity had no effect (neither common nor unique) on the dependent variable. The total explained variance of the dependent variable was R² = 0.46. The study isolated four predictors of prejudice towards childfree individuals: right-wing authoritarianism, political beliefs, collective narcissism, and religiosity. This provides a better understanding of the possible origin of prejudice towards childfree individuals and allows us to explore the relation between these predictors in the future. These results can be used to promote more positive attitudes towards childfree individuals as well as create more targeted actions to tackle the prejudice towards them.

波兰对无子女个人的偏见的预测因素

选择不生孩子的人经常会面临误解和缺乏他人的接受。在许多情况下，这会导致消极态度，进而导致歧视和偏见。很少有研究能够让我们确定哪些特征导致对无子女的个体产生偏见。本研究旨在探讨可能影响他人对无子女个体的偏见的五种可能特征的影响：集体自恋、右翼威权主义、宗教信仰、政治信仰和生育能力。该研究在波兰进行，共有 229 名参与者（年龄 19-59 岁，M  = 30.23；SD  = 6.72）。进行了共性分析，使我们能够分离出可能的预测变量对因变量（偏见）的独特影响和共同影响。右翼威权主义、政治信仰和集体自恋对因变量既有独特的影响，又有共同的影响。宗教信仰仅对偏见有共同影响，而生成性对因变量没有影响（既不共同也不独特）。因变量的总解释方差为R ²  = 0.46。该研究分离出对无子女个人存在偏见的四个预测因素：右翼威权主义、政治信仰、集体自恋和宗教信仰。这可以更好地理解对无子女个体的偏见的可能根源，并使我们能够在未来探索这些预测因素之间的关系。这些结果可用于促进对无子女个人采取更积极的态度，并制定更有针对性的行动来解决对他们的偏见。
