Psychometric Validation of Emotional Reaction Instrument-English to Measure American Children'S Emotional Responses to Hospitalisation

AIMS AND OBJECTIVES: The aim of this study was to test the initial psychometric properties of the Emotional Reactions Instrument-English with hospitalised American children, ages 7-12 years, in the USA. BACKGROUND: Children's negative emotional responses have been a subject of concern for paediatric clinicians and researchers, especially because negative emotional responses following or during hospitalisation are associated with adverse patient outcomes. Existing self-report paediatric instruments have a number of limitations including lack of clinical feasibility and psychometric evidence. DESIGN: A survey and psychometric approach was used to test initial reliability and validity of the Emotional Reactions Instrument-ENGLISH. METHODS: Two hundred hospitalised American children, 7-12 years of age, who were admitted to a Children's Hospital in the USA were recruited for this study. The children were administered the Emotional Reactions Instrument-English, the Facial Affective Scale, and a demographic form. RESULTS: Internal consistency was supported by a Cronbach's alpha of 0·83 for the total scale. Alpha coefficients for subscales ranged from 0·59-0·82. Construct validity was tested with exploratory factor analysis. Through principal component analysis, four factors were identified that explained 64% of the variance. Concurrent validity was supported by most items in the Emotional Reactions Instrument-English being significantly correlated with the Facial Affective Scale (r = 0·18-0·59). The instrument can be administered to hospitalised children in 5-10 minutes. CONCLUSIONS: The results of this exploratory study provide initial support for the psychometric adequacy of the Emotional Reactions Instrument-English with hospitalised American children ages 7-12 years. Further testing of the Emotional Reactions Instrument-English is required to validate the subscales and evaluate the instrument's use with children of different ages, race and ethnicity. RELEVANCE TO CLINICAL PRACTICE: This study introduces a new, clinically feasible instrument to measure children's diverse emotional responses to hospitalisation.
