Formulation and validity and reliability testing of oral feeding preparation scale for premature baby or low birth weight infant

Abstract

Objective To design the oral feeding preparation scale for premature baby or low birth weight infant, and test its validity and reliability. Methods We utilized method of literature review, consulted experts, and combined with clinical experience to protocol the clause of initial scale. A total of 114 premature babies had been chosen to survey. The scale was evaluated by program analysis, exploratory factor analysis, correlation analysis, internal consistency testing, split-half reliability analysis, content validity, etc. Results The initial clauses were 14, and after discussions, program analysis, exploratory factor analysis, we deleted 3 clauses and added 1. The exploratory factor distilled 5 common factors; its cumulative contribution rate reached 77.639%, and correlation coefficient of each dimension was 0.443-0.999; Cronbach′s α coefficient and split-half coefficient maintained 0.778 and 0.880. The outcome scale of different oral feeding ways had statistical significance (P<0.05), and had some certain differentiate validity. Conclusions The validity of oral feeding preparation scale for premature babies or low birth weight infant is good, which can be the measure tool for assessment of premature babies or low birth weight infant′s oral feeding preparation.
