Insights
The Early Feeding Skills (EFS) tool is a valid and reliable instrument for assessing infant feeding development. Its strong psychometric properties support its use in clinical practice and future research.
Area of Science:
- Neonatal and pediatric feeding interventions.
- Clinical assessment tools for infant development.
Background:
- Assessing infant feeding skills is crucial for neonatal and pediatric care.
- The Early Feeding Skills (EFS) tool aids in evaluating early feeding abilities and identifying intervention needs.
Purpose of the Study:
- To determine the factor structure of the EFS tool.
- To evaluate the psychometric properties of the EFS, including reliability and validity.
Main Methods:
- 142 infant feeding observations (33-50 weeks postmenstrual age) were scored by trained clinicians.
- Factor analysis was used to identify subscales after removing redundant items.
- Construct validity was assessed against the Infant-Driven Feeding Scale-Quality (IDFS-Q) and infant gestational age.
Main Results:
- A 5-factor structure was supported by principal components analysis.
- The EFS demonstrated good internal consistency reliability (Cronbach α=0.81).
- The EFS showed construct validity with the IDFS-Q (r=-0.73) and gestational age (r=0.22).
Conclusions:
- The EFS is a valid and reliable tool for interprofessional feeding teams to organize assessments and plan care.
- The robust psychometric properties of the EFS support its application in future research.
Background:
Supporting infants as they develop feeding skills is an essential component of neonatal and pediatric care. Selecting appropriate and supportive interventions begins with a thorough assessment of the infant's skills. The Early Feeding Skills (EFS) tool is a clinician-reported instrument developed to assess the emergence of early feeding skills and identify domains in need of intervention.
Purpose:
The purpose of this study was to identify the factor structure of the EFS and test its psychometric properties, including internal consistency reliability and construct validity.
Methods:
EFS-trained interprofessional clinicians in 3 settings scored 142 feeding observations of infants 33 to 50 weeks' postmenstrual age. Redundant and rarely endorsed items were removed. Factor analysis methods clustered items into subscales. Construct validity was examined through the association of the EFS with (1) concurrently scored Infant-Driven Feeding Scale-Quality (IDFS-Q), (2) infant birth risk (gestational age), and (3) maturity (postmenstrual age).
Results:
Principal components analysis with varimax rotation supported a 5-factor structure. The total EFS demonstrated good internal consistency reliability (Cronbach α= 0.81). The total EFS score had construct validity with the IDFS-Q (r =-0.73; P < .01), and with gestational age of a subsample of premature infants (r = 0.22; P < .05).
Implications For Practice:
As a valid and reliable tool, the EFS can assist the interprofessional feeding team to organize feeding assessment and plan care.
Implications For Research:
The strong psychometric properties of the EFS support its use in future research.
