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.
Abstract:
The Questionnaire for Crying, Feeding and Sleeping of an infant, constructed based on theory and factor analysis, is assessed for internal consistency, inter-correlations, and its relation to a behaviour diary. A clinical and a non-clinical sample are compared. The sample of in total 704 infants younger than one year consists of different subsamples. To test the differences between a clinical and a non-clinical sample assessed with the questionnaire, data of 134 infants brought to the outpatient unit for parents with their infants and toddlers and a matched sample are used. The principal components analysis results in three well-interpretable scales correlating with each other, which all show a high internal consistency. The connections to the diary records and the differences between the means of the clinical and the non-clinical sample are found in the expected directions. The results of the Questionnaire for Crying, Feeding and Sleeping, including the criterion of Wessel, are consistent with the behaviour diary as well as the clinical diagnostics. The Questionnaire for Crying, Feeding and Sleeping shows validity according to these criteria and can therefore be used in research and clinical practise for the assessment of problems concerning crying, feeding and sleeping in the first year of life.
