A Middle‐Range Theory for Nurses to Diagnose Ineffective Infant Feeding Patterns

PURPOSE To construct a middle‐range theory, based on the Roy adaptation model, for nurses can diagnose an ineffective infant feeding pattern. DATA SOURCE Scientific findings were used through a literature review and the concepts of the Roy model. DATA SYNTHESIS The theory indicated new elements for the diagnosis: 12 etiological factors and 13 clinical indicators. Most of those are not contained in the NANDA taxonomy. CONCLUSION The middle‐range theory for these diagnoses highlights the need for a review of the components present in the taxonomy. IMPLICATIONS FOR NURSING PRACTICE This approach guides research on nursing diagnoses to revise the content of the theory and to expand its concepts and elements for the diagnosis of an ineffective infant feeding pattern.
