Missingness Amount and Mechanisms in Family Economic Stress Research: Mapping (Non)answers to Economic-Related Variables of Fathers, Mothers, and Emerging Adult Children

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.
