In this study, we examined whether infant temperament predicted study dropout at 3.5 and 7 months and whether dropout was stable across time. Dropout was measured across four experimental tasks (free-play, ERP, still-face, and eye tracking). Temperament was not related to dropout at either timepoint. Dropout was not stable across time, nor was it stable across tasks. These findings suggest that individual differences in temperament are not systematically related to study completion across experimental tasks with varied requirements. These findings additionally suggest that dropout is not consistent across tasks, which may support the utility of multi-study data collection methods.
