OBJECTIVE Whether children with attention deficit hyperactivity disorder (ADHD) have deficits in sustained attention remains unresolved due to the ongoing use of cognitive paradigms that are not optimized for studying vigilance and the fact that relatively few studies report performance over time. METHOD In three independent samples of school-age children with (total N = 128) and without ADHD (total N = 59), we manipulated event rate, difficulty of discrimination, and use signal detection (SDT) and diffusion models (DM) to evaluate the cause of the vigilance decrement during a continuous performance task. RESULTS For both groups of children, a bias toward "no-go" over time (as indexed by the SDT parameter B″ and the DM parameter z/a) was responsible for generating the vigilance decrement. However, among children with ADHD, the rate at which information accumulated to make a no-go decision (vNoGo) also increased with time on task, representing a possible secondary mechanism that biases children against engagement. At all time points, children with ADHD demonstrated reduced sensitivity to discriminate targets from nontargets. CONCLUSION Children with ADHD are particularly sensitive to the cost of task engagement, but nonspecific slower drift rate may ultimately provide a better conceptualization of the cognitive atypicalities commonly observed in that group.

Accordingly, the present study was conducted as a longitudinal assessment of the predictive utility of pain resilience and pain catastrophizing as indicators of clinical outcomes among patients receiving a standardized treatment for chronic pain. METHOD Using an observational design, analyses were conducted on measures of pain resilience, pain catastrophizing, quality of life, and clinical pain administered to 149 patients upon admission and prior to discharge from an 8-week outpatient functional restoration program. Hierarchical linear regressions were conducted to predict improvement in physical and mental health quality of life and clinical pain intensity at discharge based on individual differences in admission levels of pain-related catastrophizing and resilience. RESULTS Results of the primary analyses indicated that pain catastrophizing and pain resilience independently predicted physical and mental health quality-of-life outcomes at discharge but did not significantly predict clinical pain intensity. Specifically, higher baseline pain resilience was associated with better quality-of-life outcomes, whereas higher baseline catastrophizing was associated with poorer outcomes. CONCLUSION This study provides additional support for the notion that pain resilience assessment may help identify those most likely to benefit from targeted efforts to bolster resilience resources during treatment.

The purpose of the present study was to examine whether affect variability was associated with inflammation in ways consistent with the stability theory or the fragile positive affect theory, and whether associations were linear or nonlinear. METHOD In a racially diverse sample (N = 231; Aged 25-65; 65% female; 62% Black; 25% Hispanic), we examined whether positive affect (PA) and negative affect (NA) variability exhibited linear or quadratic associations with circulating inflammatory cytokines (a composite measure comprised of IL-1β, IL-4, IL-6, IL-8, IL-10, TNF-α, IFN-γ), and C-reactive protein (CRP) and whether person-mean affect moderated these associations. Affective states were assessed using ecological momentary assessments (EMAs) 5 times per day for 2 weeks, with a blood draw at the end of the EMA period. Individual standard deviations of affective states indexed affect variability. RESULTS A quadratic association indicated that moderate NA variability was associated with lower CRP. There was evidence of significant moderation by linear associations with PA only For those with higher person-mean PA, PA variability was positively associated with the cytokine composite. Both person-mean PA and person-mean NA moderated quadratic associations, such that for those with high person-mean affect, both high and low affect variability was associated with systemic inflammation. CONCLUSION Results are in line with fragile affect theory suggesting that associations between affect variability and health indicators may vary by person-mean affect.

However, findings from daily life studies examining the interaction of motives and affect to predict alcohol use are mixed. Individuals with borderline personality disorder (BPD) may be particularly susceptible to drinking for the purpose of changing affective states, representing a population in which these patterns may be more readily identifiable in daily life. We tested whether drinking motives moderate daily life associations between affect and drinking in individuals with BPD. Regular drinkers with BPD (N = 54; 81.5% female) completed ecological momentary assessments approximately 6-10 times daily for 21 days. We tested whether the interactions between (a) person-level coping motives and NA so far that day (i.e., cumulative-average NA), and (b) person-level enhancement and cumulative-average PA were associated with subsequent drinking. We also tested whether effects differed for the initiation versus continuation of a drinking episode.
