Abstract

While preparing an unrelated follow-up project using the original sample, the authors of Ait Oumeziane and Foti (2016) found an error wherein approximately fifty percent of the study data was affected. We have corrected this error, and the corrected results are shared here. Most importantly, the key reward positivity findings remain nearly identical: we observed an interaction between depression and positive urgency in predicting reward positivity amplitude to monetary gain trials; this effect was moderated by age, such that the depression x positive urgency interaction was specific to younger adults and not observed among older adults. Regarding our secondary findings, we found a significant interaction between depression and impulsivity (i.e., depression x lack of perseverance) among older adults in predicting P3 amplitude. This significant pattern was between another impulsivity facet than previously reported (i.e., lack of premeditation). The abstract has been amended and the corrected tables and figure shown below: AbstractRecent theoretical models underline reward sensitivity as a potential endophenotype for major depressive disorder. Neural and behavioral evidence reveals depression is associated with reduced reward sensitivity. However, reward dysfunction is not unique to depression, as it is also common across disorders of poor impulse control. We examined the interrelationships of depression (Depression, Anxiety, and Stress Scale ) and impulsivity (UPPS-P Impulsive Behavior Scale) with reward sensitivity among a large, representative sample (N 5 259). ERPs were recorded to isolate two neural indicators of consummatory reward processing: initial evaluation of rewards in the 250-350 ms time window poston set of feedback (reward positivity [RewP]), and salience to monetary outcomes (P3). Significant interactions were observed between depression and impulsivity facets across these two stages of reward processing: depression and positive urgency predicted RewP amplitude to monetary gains among younger participants; depression and one other impulsivity trait, (lack of) perseverance, predicted P3 amplitude to monetary outcomes among older adults. Conversely, lower symptoms of depression were related to one biobehavioral profile: high P3 amplitude in conjunction with high (lack of) perseverance only among older adults. Findings illustrate that reward-related dysfunctions may be optimally conceptualized when examining the interactions between dimensions of internalizing and externalizing psychopathology across the lifespan.
