Compared with cross-sectional studies, longitudinal studies present the possibility of a greater range of non-sampling errors. Because of this, the entire process covering study design, fieldwork, and data processing must be carefully planned in advance. Leading longitudinal studies in other countries have conducted various methodological studies to improve the data that are collected and released. In contrast, it is difficult to find instances of methodological studies in the field of longitudinal research in Korea. This study is the first to study mode effects in Korean longitudinal studies. In essence, it concerns the empirical analysis of the question “How did the introduction of CAPI (computer-assisted personal interviewing) affect the data quality of certain longitudinal studies?” This question is examined using KLI’s (Korea Labor Institute’s) KLIPS (Korean Labor and Income Panel Study), which is among the first of Korea’s longitudinal studies to have introduced the CAPI mode.
