The aim of this study was to validate the content and check the reliability of a tool to assess the behavior of the preterm infants aged 28 - 33 weeks of gestational Age following a Developmental Supportive Care (DSC) Intervention. A multidisciplinary panel of seven national and international experts was selected to assess, review, and suggest modifications for the tool. The tool had two subsystems. One was the autonomic/visceral system consisting of four domains namely colour, respiration, visceral signs and neurophysiological responses. The second was the state and attention-interaction system, consisting of three domains namely state regulation, orientation to auditory stimulus and alertness. A validity questionnaire was keyed to the individual items clustered under the two subsystems and the initial draft of the tool was mailed to the content experts along with the objectives, aim and the blueprint of the tool. Experts were from the field of Pediatrics, Neonatology, Developmental Psychology, Perinatal nursing and Neonatal nursing. Data were analyzed using descriptive statistics. The Content Validity Index (CVI) for each item as well as the overall CVI were calculated. All the seven experts completed the validity questionnaires. The experts generally agreed that the items of the initial draft were clearly worded, appropriate and relevant. The tool obtained a high overall CVI score of 0.95, yielding a valid tool for assessing behavior of the preterm infants. To check the reliability of the tool, two raters observed 40 preterm infants for duration of 30 minutes following the provision of 30 minutes of the DSC intervention. The inter-rater reliability was checked using Intra class correlation coefficients (ICC). Calculation was done using SPSS (Ver.15.0), South East Asia, Bangalore for raw scores obtained by two independent observers for the two subsystems namely the autonomic and state and attention-interaction systems and their domains in the tool. The 'R' value obtained for the autonomic subsystem was 0.96 whereas the 'R' obtained for the state and attention-interaction subsystem was 0.92, which indicates high reliability for both the subsystems of the tool. The findings reported suggest that the tool has potential for use as both a clinical as well as a research instrument to assess behaviors of preterm infants who are provided DSC interventions.
