The percentage of missing data among economic-related items is likely to be particularly high. This study aimed at examining the amount, mechanisms, and variables associated with missingness of different family members participating in a family economic stress study. Portuguese emerging adults (N = 418) and their parents (N = 748) were required to answer objective and subjective economic items and complete measures assessing individual and family psychological functioning. Results showed that, for all participants, non-response was more likely to occur among objective economic items than among subjective ones. Children presented higher percentages of item/construct-level missingness than parents, which could reflect a reduced financial awareness on the part of these family members. Although the identification of mechanisms explaining missing data proved to be complex, family members’ missingness was associated with sociodemographic and psychological indicators, suggesting that non-answers do not occur purely by chance. Implications of these findings for further family economic stress research are discussed.

在与经济有关的项目中丢失数据的百分比可能特别高。这项研究旨在研究与参与家庭经济压力研究的不同家庭成员的失踪有关的数量，机制和变量。要求葡萄牙新兴成年人（N = 418）及其父母（N = 748）回答客观和主观的经济项目，并评估个人和家庭的心理功能。结果表明，对所有参与者而言，客观经济项目比主观经济项目更容易发生无反应。与父母相比，儿童的物品/构造物失窃百分比更高，这可能反映出这些家庭成员的经济意识下降。尽管确定解释缺失数据的机制非常复杂，但家庭成员的缺失与社会人口统计学和心理指标有关，这表明非答案并非纯属偶然。讨论了这些发现对进一步家庭经济压力研究的意义。
