This study examines attrition rates over the first four years of the New Zealand Attitudes and Values Study, a longitudinal national panel sample of New Zealand adults. We report the base rate and covariates for the following four distinct classes of respondents: explicit withdrawals, lost respondents, intermittent respondents and constant respondents. A multinomial logistic regression examined an extensive range of demographic and socio-psychological covariates (among them the Big-Six personality traits) associated with membership in these classes (N = 5,814). Results indicated that men, Māori and Asian peoples were less likely to be constant respondents. Conscientiousness and Honesty-Humility were also positively associated with membership in the constant respondent class. Notably, the effect sizes for the socio-psychological covariates of panel attrition tended to match or exceed those of standard demographic covariates. This investigation broadens the focus of research on panel attrition beyond demographics by including a comprehensive set of socio-psychological covariates. Our findings show that core psychological covariates convey important information about panel attrition, and are practically important to the management of longitudinal panel samples like the New Zealand Attitudes and Values Study.
本研究考察了新西兰态度与价值观研究（一项针对新西兰成年人的全国性纵向面板样本研究）前四年的样本损耗率。我们报告了以下四类不同受访者的基准率和协变量：明确退出者、失联受访者、间歇性受访者和持续受访者。一项多项逻辑回归分析考察了与这些类别归属相关的广泛的人口统计学和社会心理协变量（其中包括大五人格特质）（N = 5814）。结果表明，男性、毛利人和亚洲人成为持续受访者的可能性较小。尽责性和诚实谦逊也与持续受访者类别归属呈正相关。值得注意的是，面板损耗的社会心理协变量的效应大小往往与标准人口统计学协变量的效应大小相当或更大。这项调查通过纳入一套全面的社会心理协变量，拓宽了面板损耗研究的重点，使其超越了人口统计学范畴。我们的研究结果表明，核心心理协变量传达了有关面板损耗的重要信息，对于像新西兰态度与价值观研究这样的纵向面板样本管理具有实际重要意义。
