Objective: This study sought to examine the utility of emotional intra-individual variability (IIV) as a marker of psychopathology. Method: Data from 686 individuals who completed a psychoeducational evaluation that included the Personality Assessment Inventory (PAI) and the Beck Depression Inventory-II (BDI-II) were utilized. Mean demographics: age 23.22 (SD 6.71, range: 16–65), and education 13.96 (SD 2.18, range: 3 – 34). The sample was 50.3% male and 83.5% Caucasian. Individuals were divided into four groups based on BDI-II score: no depression (N = 183) (0–5), minimal depression (N= 137) (6–10), mild to moderate depression (N= 220) (11–20), and moderate to severe depression (N= 146) (>20). Emotional IIV was computed for each individual as their own standard deviation around their own mean performance across the PAI clinical scales. Results: Pearson correlation indicated a moderate association between BDI-II score and emotional IIV from the PAI, r = .42, p < .01. ANOVA was used to evaluate differences between the BDI-II severity groups and emotional IIV. A significant main effect was found [F (3,682)= 40.89, p < .001]. Tukey HSD post-hoc comparisons key's HSD test indicated that the no depression group (M 6.95, SD 2.69) and moderate to severe depression group (M 10.35, SD 3.06) differed significantly from all other groups except the minimal depression group (M 8.27, SD 2.63) and mild to moderate depression group (M 8.79, SD 2. 84) did not differ from each other for emotional IIV. Conclusion: These results suggest that greater levels of IIV on inventories of emotional and personality functioning may be associated with increased psychopathology.
