    Infant temperament influences study completion. Noncompleters showed difficult temperaments, unlike completers, suggesting temperament impacts infant research validity.

    Area of Science:

    • Developmental Psychology
    • Infant Behavior Research

    Background:

    • Infant temperament is crucial for understanding developmental trajectories.
    • Variability in infant participation can affect research outcomes.

    Purpose of the Study:

    • To investigate temperament differences between infants who complete and do not complete a visual habituation study.
    • To explore the relationship between infant temperament and study attrition in research.

    Main Methods:

    • Compared temperament profiles of 24 Caucasian infants (16 completers, 8 noncompleters) in a visual habituation study.
    • Utilized maternal ratings from the Infant Temperament Questionnaire Revised (ITQ-R).

    Main Results:

    • Noncompleters exhibited more arrhythmic, withdrawing, and intense temperaments compared to completers.

  • Noncompleters were less distractible and more likely classified as 'difficult' babies.
  • Completers were more often classified as 'easy' babies.

    • Conclusions:

    • Infant temperament, particularly 'difficult' traits, is associated with noncompletion in research studies.
    • Accurate descriptions of participants, including completers and noncompleters, enhance the external validity of infant research.
    • Consideration of infant temperament may improve participant retention in developmental studies.
