Objective: The NIH Toolbox Emotion Battery (hereafter, EB) was developed to capture the full spectrum of emotional functioning. This study describes some psychometric properties of the EB and the impact of demographic variables on emotional functioning in the national normative sample. Method: 1172 adults were tested in English. The adult EB is < 30-minutes, computer-administered and includes 17 scales for ages 18–85. We combined the scales into Positive Emotion (PE) and Negative Emotion (NE) summary scores. All participants also completed the NIH-TB Cognition Battery (uncorrected Fluid and Crystallized Composite scores) and 240 participants also completed items on marital status and social contact (SC), defined as number of social interactions in 2 weeks. Results: Only results with p < .001 are reported. Inter-scale correlations on the PE and NE summary scores ranged from 0.53–0.81, supporting their internal consistency. PE and NE demonstrated strong, negative associations with one another (r = −.71). Older age was associated with lower negative affect (r = −.19). Higher education had small, but consistently positive associations with emotion, whereas gender was not significantly associated with either summary score. Greater household incomes (PE r = .21, NE r = −.14), married status (PE d = .48; NE d = 0.43), and increased social contact (PE r = .32) were associated with better emotional functioning. Regarding cognition, Fluid abilities demonstrated small, but positive associations with PE (r = .12), whereas Crystalized abilities had no significant association with either PE or NE. Conclusion: Demographic effects on EB in a normal sample are modest but favor married status and higher education. Associations of EB with cognition may be stronger in clinical samples with acquired cognitive impairment.
