This article aims to analyze the main theoretical and methodological challenges associated with the use of longitudinal research designs in Work and Organizational Psychology. Longitudinal designs with three or more points of measurement are rare in the literature. Critical points to be observed include: definition of the interval between first and last measurement of variables, time needed for the effect of an intervention to become observable, quantity of measurements over time, time period between measurements, management of participant drop outs, and analysis of alternative explanations for the effects of interventions or programs. The technical recommendations offered include the use of designs with multiple measurements of independent and dependent variables, such as external variables that threaten the internal and external validity of study conclusions.

Keywords : research method; longitudinal design; Work and Organizational Psychology.
