This study describes a major effort to reinstate dropouts from the MIDUS longitudinal study and compare baseline characteristics among subgroups of participants to better understand predictors of retention, attrition, and reinstatement. All living dropouts were contacted, and 651 reinstated participants were interviewed in person (31.4% response rate). Age, gender, education, marital status, parental status, and physical and mental health were compared among the following groups: longitudinal sample, reinstated sample, those fielded for reinstatement who did not return, and those who dropped out at the 2nd or 3rd wave. Multivariate analyses revealed that reinstated participants were younger, male, unmarried, and less educated and had children at baseline compared to longitudinal participants. Reinstatement was unsuccessful among those with poorer mental health at baseline compared to longitudinal participants. This study informs reinstatement efforts, adjustment for attrition bias, and use of to examine aging consequents of early life vulnerability.
这项研究描述了一项重大努力，旨在重新招募 MIDUS 纵向研究的辍学者，并比较参与者亚组的基线特征，以更好地了解保留、流失和重新招募的预测因素。所有在世的辍学者都被联系到了，其中 651 名重新招募的参与者接受了面对面访谈（回应率为 31.4%）。在以下组之间比较了年龄、性别、教育、婚姻状况、父母状况以及身心健康：纵向样本、重新招募样本、那些为重新招募而派出但未返回的样本，以及那些在第 2 或第 3 波中辍学的样本。多变量分析显示，与纵向参与者相比，重新招募的参与者年龄更小、男性、未婚、受教育程度较低，并且在基线时有孩子。与纵向参与者相比，基线心理健康状况较差的人重新招募不成功。这项研究为重新招募工作提供了信息，调整了流失偏差，并使用来检查早期生活脆弱性对衰老的影响。
