Assessment of health-related quality of life for individuals born very preterm and/or low birthweight (VP/VLBW) offers valuable complementary information alongside biomedical assessments. However, the impact of VP/VLBW status on health-related quality of life in adulthood is inconclusive. The objective of this study was...article 2023

Cai, M. (author), van Buuren, S. (author), Vink, G. (author)Fully conditional specification (FCS) is a convenient and flexible multiple imputation approach. It specifies a sequence of simple regression models instead of a potential complex joint density for missing variables. However, FCS may not converge to a stationary distribution. Many authors have studied the convergence properties of FCS when...article 2023

Eekhout, I. (author), van Buuren, S. (author), Visser, B. (author), Bink, M.C.A.M. (author), Huisman, A. (author)Intensive longitudinal data can be used to explore important associations and patterns between various types of inputs and outcomes. Nonlinear relations and irregular measurement occasions can pose problems to develop an accurate model for these kinds of data. This paper focuses on the development, fitting and evaluation of a prediction model...article 2023

van Buuren, S. (author)Many longitudinal studies collect data that have irregular observation times, often requiring the application of linear mixed models with time-varying outcomes. This paper presents an alternative that splits the quantitative analysis into two steps. The first step converts irregularly observed data into a set of repeated measures through the...article 2023

Austin, P.C. (author), Giardiello, D. (author), van Buuren, S. (author)We examined the setting in which a variable that is subject to missingness is used both as an inclusion/exclusion criterion for creating the analytic sample and subsequently as the primary exposure in the analysis model that is of scientific interest. An example is cancer stage, where patients with stage IV cancer are often excluded from the...article 2023

Cai, M. (author), van Buuren, S. (author), Vink, G. (author)In most medical research, the average treatment effect is used to evaluate a treatment's performance. However, precision medicine requires knowledge of individual treatment effects: What is the difference between a unit's measurement under treatment and control conditions? In most treatment effect studies, such answers are not possible because...article 2022

Fopma, A. (author), Cai, M. (author), van Buuren, S. (author), Vink, G. (author)Curve matching is a prediction technique that relies on predictive mean matching, which matches donors that are most similar to a target based on the predictive distance. Even though this approach leads to high prediction accuracy, the predictive distance may make matches look unconvincing, as the profiles of the matched donors can substantially...article 2022

Kavelaars, X.M. (author), van Buuren, S. (author), van Ginkel, J.R. (author)Multiple imputation is a highly recommended technique to deal with missing data, but the application to longitudinal datasets can be done in multiple ways. When a new wave of longitudinal data arrives, we can treat the combined data of multiple waves as a new missing data problem and overwrite existing imputations with new values (re-imputation)...article 2022

Cai, M. (author), van Buuren, S. (author), Vink, G. (author)Missing data are often dealt with multiple imputation. A crucial part of the multiple imputation process is selecting sensible models to generate plausible values for incomplete data. A method based on posterior predictive checking is proposed to diagnose imputation models based on posterior predictive checking. To assess the congeniality of...article 2022

Eekhout, I. (author), van Buuren, S. (author), Verkerk, P. (author)There are many milestones available to measure child development in the first years of life. For less experienced professionals it is difficult to select the most relevant milestones to assess the developmental status of a child. Moreover, using the milestones separately makes is difficult to get a global impression of the developmental status....public lecture 2022
