Insights

The Questionnaire for Crying, Feeding and Sleeping demonstrates validity for assessing infant issues. This tool accurately measures crying, feeding, and sleeping problems in infants up to one year old.

Area of Science:

  • Pediatrics
  • Developmental Psychology

Background:

  • Infant behavioral issues like crying, feeding, and sleeping problems are common.
  • Accurate assessment tools are crucial for timely intervention and support.

Purpose of the Study:

  • To validate the Questionnaire for Crying, Feeding and Sleeping (CFS) for infants.
  • To assess the questionnaire's internal consistency, inter-correlations, and relation to behavioral diaries.
  • To compare clinical and non-clinical infant samples using the CFS.

Main Methods:

  • Factor analysis and principal components analysis were used to construct and evaluate the CFS.
  • Data from 704 infants (under one year) were analyzed, including a clinical sample of 134 infants.
  • The CFS was correlated with behavior diary records and compared against clinical diagnostics.

Main Results:

  • Principal components analysis yielded three interpretable scales with high internal consistency.
  • The CFS scores correlated with behavior diary entries and showed expected differences between clinical and non-clinical groups.
  • Results aligned with Wessel's criteria, behavior diaries, and clinical diagnoses.

Conclusions:

  • The Questionnaire for Crying, Feeding and Sleeping is a valid and reliable tool.
  • The CFS can be effectively used in both research and clinical practice for assessing infant problems in the first year of life.
