[Ab] Resumo:Excess consumption of added dietary sugars is related to multiple metabolic problems and adverse health conditions. Identifying the modifiable social cognitive and motivational constructs that predict sugar consumption is important to inform behavioral interventions aimed at reducing sugar intake. We tested the efficacy of an integrated dual-process, dual-phase model derived from multiple theories to predict sugar consumption. Using a prospective design, university students (N = 90) completed initial measures of the reflective (autonomous and controlled motivation, intentions, attitudes, subjective norm, perceived behavioral control), impulsive (implicit attitudes), volitional (action and coping planning), and behavioral (past sugar consumption) components of the proposed model. Self-reported sugar consumption was measured two weeks later. A structural equation model revealed that intentions, implicit attitudes, and, indirectly, autonomous motivation to reduce sugar consumption had small, significant effects on sugar consumption. Attitudes, subjective norm, and, indirectly, autonomous motivation to reduce sugar consumption predicted intentions. There were no effects of the planning constructs. Model effects were independent of the effects of past sugar consumption. The model identified the relative contribution of reflective and impulsive components in predicting sugar consumption. Given the prominent role of the impulsive component, interventions that assist individuals in managing cues-to-action and behavioral monitoring are likely to be effective in regulating sugar consumption.

[Ti] Título:When hunger does (or doesn't) increase unhealthy and healthy food consumption through food wanting: The distinctive role of impulsive approach tendencies toward healthy food.

[Ab] Resumo:OBJECTIVE: Hunger indirectly triggers unhealthy high-calorie food consumption through its positive effect on the incentive value (or "wanting") for food. Yet, not everyone consumes unhealthy food in excess, suggesting that some individuals react differently when they are exposed to unhealthy high-calorie food, even when they are hungry. The purpose of the present study was to investigate whether individual differences in impulsive approach tendencies toward food may explain how, and for whom, hunger will influence unhealthy food consumption through its effect on food wanting. A complementary goal was to explore whether these individual differences also influence healthy food consumption. METHODS: Students (N = 70) completed a questionnaire measuring their hunger and food wanting. Then, they performed a manikin task designed to evaluate their impulsive approach tendencies toward unhealthy food (IAUF) and healthy food (IAHF). The main outcomes variables were the amount of sweets (i.e., unhealthy food) and raisins (i.e., healthy food) consumed during a product-testing task. RESULTS: A moderated mediation analysis revealed that the indirect effect of hunger on unhealthy consumption through food wanting was moderated by IAHF. Specifically, hunger positively predicted sweets consumption through wanting for food among individuals with a low or moderate, but not high IAHF. The moderated mediation pattern was, however, not confirmed for IAUF. Finally, results revealed a direct and positive effect of IAHF on raisins consumption. CONCLUSION: These findings showed that IAHF play a protective role by preventing hunger to indirectly increase unhealthy food consumption through wanting for food. It confirms the importance of considering how individuals may differ in their impulsive approach tendencies toward food to better understand why some individuals will increase their unhealthy food intake when they are hungry, whereas other will not.

[Ti] Título:Impulsive Rats Exhibit Blunted Dopamine Release Dynamics during a Delay Discounting Task Independent of Cocaine History.

[Ab] Resumo:The inability to wait for a large, delayed reward when faced with a small, immediate one, known as delay discounting, has been implicated in a number of disorders including substance abuse. Individual differences in impulsivity on the delay discounting task are reflected in differences in neural function, including in the nucleus accumbens (NAc) core. We examined the role of a history of cocaine self-administration, as well as individual differences in impulsivity, on rapid dopamine (DA) release dynamics in the NAc core. Rats with a history of cocaine or water/saline self-administration were tested on delay discounting while being simultaneously assayed for rapid DA release using electrochemical methods. In controls, we found that cue DA release was modulated by reward delay and magnitude, consistent with prior reports. A history of cocaine had no effect on either delay discounting or DA release dynamics. Nonetheless, independent of drug history, individual differences in impulsivity were related to DA release in the NAc core. First, high impulsive animals exhibited dampened cue DA release during the delay discounting task. Second, reward delay and magnitude in high impulsive animals failed to robustly modulate changes in cue DA release. Importantly, these two DAergic mechanisms were uncorrelated with each other and, together, accounted for a high degree of variance in impulsive behavior. Collectively, these findings demonstrate two distinct mechanisms by which rapid DA signaling may influence impulsivity, and illustrate the importance of NAc core DA release dynamics in impulsive behavior.

[Ti] Título:Risk preferences impose a hidden distortion on measures of choice impulsivity.

[Ab] Resumo:Measuring temporal discounting through the use of intertemporal choice tasks is now the gold standard method for quantifying human choice impulsivity (impatience) in neuroscience, psychology, behavioral economics, public health and computational psychiatry. A recent area of growing interest is individual differences in discounting levels, as these may predispose to (or protect from) mental health disorders, addictive behaviors, and other diseases. At the same time, more and more studies have been dedicated to the quantification of individual attitudes towards risk, which have been measured in many clinical and non-clinical populations using closely related techniques. Economists have pointed to interactions between measurements of time preferences and risk preferences that may distort estimations of the discount rate. However, although becoming standard practice in economics, discount rates and risk preferences are rarely measured simultaneously in the same subjects in other fields, and the magnitude of the imposed distortion is unknown in the assessment of individual differences. Here, we show that standard models of temporal discounting -such as a hyperbolic discounting model widely present in the literature which fails to account for risk attitudes in the estimation of discount rates- result in a large and systematic pattern of bias in estimated discounting parameters. This can lead to the spurious attribution of differences in impulsivity between individuals when in fact differences in risk attitudes account for observed behavioral differences. We advance a model which, when applied to standard choice tasks typically used in psychology and neuroscience, provides both a better fit to the data and successfully de-correlates risk and impulsivity parameters. This results in measures that are more accurate and thus of greater utility to the many fields interested in individual differences in impulsivity.

[Ti] Título:The dimensionality of impulsivity: Perspectives and implications for emerging adult drinking.

[Ab] Resumo:Heightened impulsivity is a risk factor for problematic alcohol use among emerging adults. However, recent literature suggests that impulsivity is comprised of several facets that have shown differential relationships with alcohol use versus alcohol-related problems. Previous reviews have noted the bivariate associations between facets and alcohol use outcomes, but have not honed in on which facets may explain more variance in alcohol-related outcomes once other facets are accounted for. As such, certain facets may be more relevant than others in predicting alcohol-related harms among emerging adults. Consequently, the purpose of this review was to support the validity of discrete impulsivity facets and to identify specific facets that may pose most risk for alcohol-related harms. Based on previous research, the present review focused on five facets from the self-report impulsivity literature (i.e., sensation seeking, negative urgency, positive urgency, premeditation, and perseverance) and two facets from the behavioral impulsivity literature (i.e., impulsive action and impulsive choice). Conceptual and empirical evidence were provided to support the distinction of these self-report and behavioral facets, and literature comparing each of their relative contributions to alcohol use and alcohol-related problems, while controlling for the influence of other facets, is summarized. Overall, it is suggested that among emerging adults, sensation seeking is the strongest predictor of alcohol use whereas positive and negative urgency are the strongest predictors of alcohol-related problems. Implications and directions for future research were proposed. (PsycINFO Database Record

[Ti] Título:Environmental context effects on craving among consumers of caffeinated alcohol beverages: Associations with aspects of impulsivity.

[Ab] Resumo:The present study primarily sought to (a) determine the effects of environmental context on subjective ratings of craving for alcohol and caffeinated alcohol beverages (CAB) and (b) test inhibitory control, a state behavioral aspect of impulsivity, as a mediator of the association between context and craving in a sample of consumers of CAB. A secondary aim was to examine the associations between trait impulsivity and subjective craving for alcohol and CAB. Participants were 143 (67.1% female) college CAB drinkers. Participants were randomized into either a simulated bar context condition or neutral context condition and completed measures of alcohol use, CAB use, trait impulsivity, inhibitory control on a go/no-go task, and subjective craving for alcohol and CAB. Findings revealed that participants in the simulated bar condition, as compared with those in the neutral condition, reported more subjective craving for alcohol and for CAB; however, alcohol and CAB-specific craving were not different overall or as a function of context. The association between context and subjective craving for alcohol was not mediated by inhibitory control. Trait impulsivity was positively associated with alcohol and CAB-specific craving at baseline and post context exposure, and this finding was similar across both conditions. Therefore, the current investigation suggests that consumers of CAB may be sensitive to alcohol contexts as indicated by greater responses in alcohol and CAB-specific craving. However, inhibitory control did not explain this association. Future research may benefit from examining other potential mechanisms that explain the relationship between context and craving among CAB consumers. (PsycINFO Database Record

[Ti] Título:Response time scores on a reflexive attention task predict a child's inattention score from a parent report.

[Ab] Resumo:Compared to sustained attention, only a small proportion of studies examine reflexive attention as a component of everyday attention. Understanding the significance of reflexive attention to everyday attention may inform better treatments for attentional disorders. Children from a general population (recruited when they were from 9-16 years old) completed an exogenously-cued task measuring the extent to which attention is captured by peripheral cue-target conditions. Parents completed a questionnaire reporting their child's day-to-day attention. A general linear model indicated that parent-rated inattention predicted the increase in response time over baseline when a bright cue preceded the target (whether it was valid or invalid) but not when a dim cue preceded the target. More attentive children had more pronounced response time increases from baseline. Our findings suggest a link between a basic measure of cognition (response time difference scores) and parent observations. The findings have implications for increased understanding of the role of reflexive attention in the everyday attention of children.

[Ab] Resumo:Impulsivity, the predisposition to act prematurely without foresight, is associated with a number of neuropsychiatric disorders, including attention-deficit/hyperactivity disorder (ADHD). Identifying genetic underpinnings of impulsive behavior may help decipher the complex etiology and neurobiological factors of disorders marked by impulsivity. To identify potential genetic factors of impulsivity, we examined common differentially expressed genes (DEGs) in the prefrontal cortex (PFC) of adolescent SHR/NCrl and Wistar rats, which showed marked decrease in preference for the large but delayed reward, compared with WKY/NCrl rats, in the delay discounting task. Of these DEGs, we examined drug-responsive transcripts whose mRNA levels were altered following treatment (in SHR/NCrl and Wistar rats) with drugs that alleviate impulsivity, namely, the ADHD medications methylphenidate and atomoxetine. Prefrontal cortical genetic overlaps between SHR/NCrl and Wistar rats in comparison with WKY/NCrl included genes associated with transcription (e.g., Btg2, Fos, Nr4a2), synaptic plasticity (e.g., Arc, Homer2), and neuron apoptosis (Grik2, Nmnat1). Treatment with methylphenidate and/or atomoxetine increased choice of the large, delayed reward in SHR/NCrl and Wistar rats and changed, in varying degrees, mRNA levels of Nr4a2, Btg2, and Homer2, genes with previously described roles in neuropsychiatric disorders characterized by impulsivity. While further studies are required, we dissected potential genetic factors that may influence impulsivity by identifying genetic overlaps in the PFC of "impulsive" SHR/NCrl and Wistar rats. Notably, these are also drug-responsive transcripts which may be studied further as biomarkers to predict response to ADHD drugs, and as potential targets for the development of treatments to improve impulsivity.

[Ti] Título:An insulin resistance associated neural correlate of impulsivity in type 2 diabetes mellitus.

[Ab] Resumo:Central insulin resistance (IR) influences striatal dopamine (DA) tone, an important determinant of behavioral self-regulation. We hypothesized that an association exists between the degree of peripheral IR and impulse control, mediated by the impact of IR on brain circuits controlling the speed of executing "go" and/or "stop" responses. We measured brain activation and associated performance on a stop signal task (SST) in obese adults with type 2 diabetes (age, 48.1 ± 6.9 yrs (mean ± SD); BMI, 36.5 ± 4.0 kg/m2; HOMA-IR, 7.2 ± 4.1; 12 male, 18 female). Increasing IR, but not BMI, was a predictor of shorter critical stop signal delay (cSSD), a measure of the time window during which a go response can be successfully countermanded (R2 = 0.12). This decline was explained by an IR-associated increase in go speed (R2 = 0.13) with little impact of IR or BMI on stop speed. Greater striatal fMRI activation contrast in stop error (SE) compared with stop success (SS) trials (CONSE>SS) was a significant predictor of faster go speeds (R2 = 0.33, p = 0.002), and was itself predicted by greater IR (CONSE>SS vs HOMA-IR: R2 = 0.10, p = 0.04). Furthermore, this impact of IR on striatal activation was a significant mediator of the faster go speeds and greater impulsivity observed with greater IR. These findings suggest a neural mechanism by which IR may increase impulsivity and degrade behavioral self-regulation.

[Ab] Resumo:Self-harm refers to the purposeful destruction of bodily tissue without suicidal intention and for purposes that are not socially sanctioned. Little is known about the associations between a history of self-harm, mood symptoms, and functioning in adults with different types of mood disorders. Lifetime histories of self-harm, current mood symptoms, global functioning, and affective traits were collected on 142 adults with mood disorders. The prevalence of lifetime self-harm was higher in patients with bipolar disorder compared with patients with a unipolar depressive disorder. Self-harm was also more strongly linked to impulsivity in individuals with bipolar disorder compared with unipolar depressive disorder. Across both diagnoses, histories of self-harm were related to lower levels of current global functioning, more severe depressive symptoms, and high self-reported emotional dysregulation and neuroticism. Findings indicate that self-harm is a potent prognostic variable for symptoms, global functioning, and personality functioning in individuals with mood disorders.
