Screening Solid Foods Infants 1 (SSFI-1) development of a screening tool to detect problems in the transition from milk to solid food in infants from six to nine months of age.
Sommaire de l'article
To establish the psychometric properties of a newly developed screening tool Screening Solid Foods Infants 1 (SSFI-1) used by early childhood professionals, to detect problems in the transition from milk to solid food of smooth consistency in infants 6-9 months of age.
The SSFI-1 score was filled out by the parents of a subgroup with term infants (n=35); healthy preterm infants (n=26); infants with comorbidity (n=17); infants with feeding problems (n=13). Internal consistency, reproducibility, construct, criterion and related validity was evaluated.
The preterm subgroup differed significantly in age when starting with fruits/vegetables and period of experience (p<0.01). The SSFI-1 was sufficiently reliable for the total group and term subgroup (α±=0.78 and 0.76), but not for the preterm and comorbidity/feeding problem subgroup (α±=0.51 and 0.69). Inter-rater reliability was high for the total score (n=25, ICC r=0.93), and moderate to good for individual items (weighted kappa range 0.55-0.95). Validity was confirmed by significantly higher scores for the comorbidity/feeding problem subgroups and clinically distinguishable subgroups (p<0.05) and area under the curve values>0.78. The initial 10-item screening tool was modified to a seven item screening tool. A SSFI-1 score of 4, +2 SD of the term subgroup, had 76.9% sensitivity and 82.1% specificity, for detecting the presence of a feeding problem.
The seven-item screening tool Screening Solid Foods 1 may be used as a screening tool for term infants. Further testing of the SSFI-1 in new infants is needed, to confirm reliability and validity both for term, preterm and (risk for) feeding problem infants.
