Addict Behav Rep 2024; 20:100558. [PMID: 39027408 PMCID: PMC11252613 DOI: 10.1016/j.abrep.2024.100558] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/26/2024] [Revised: 06/02/2024] [Accepted: 06/18/2024] [Indexed: 07/20/2024] Open
Abstract
Objective The neurocognitive risk mechanisms predicting divergent outcomes likely differ between men and women who use cannabis recreationally. Increasingly, the use of descriptive distributions including the ex-Gaussian has been applied to draw stronger inferences about neurocognitive health in clinical populations. The current project examines whether the long tail of reaction times (RTs) in a distribution, as characterized by the ex-Gaussian parameter tau which may represent difficulty with the regulation of arousal, predicts problematic cannabis use 6 months later in those who use cannabis recreationally, and whether sex moderates these prospective associations. Method Young adults (ages 18-30, mean age 20.5 years, N =159, 57.2% women, 69.2% Caucasian) who recreationally used cannabis either occasionally (at least once per month) or frequently (three times or more per week) completed the Stroop Color-Word Task at baseline. Ex-Gaussian parameter tau was estimated for each participant. Self-report of hazardous cannabis use (CUDIT-R) and dysregulation of negative (DERS) and positive emotions (DERS-Positive) were obtained at baseline and 6-month follow-up. Results For those with larger tau at baseline, being a man (but not a woman) was associated with increased difficulty regulating positive emotions concurrently (b = -0.01, F (1,159) = 5.48, p = 0.02), and with hazardous cannabis use six months later (b = -0.007, F (1,159) = 4.42, p = 0.037) after controlling for baseline hazardous cannabis use. Conclusions Excessively long RTs during cognitive performance may help characterize men at risk for increased hazardous use, which contributes to understanding between-sex heterogeneity in pathways towards cannabis use disorders.

Abstract
BACKGROUND AND OBJECTIVES Research shows that individuals with heightened trait anxiety are more likely to experience intrusions; however, the mechanism that accounts for this relationship is unclear. Two alternative hypotheses were tested to determine the nature of the associations between trait anxiety, attentional bias to negative information, and intrusion vulnerability. METHODS Intrusions were elicited using the trauma film paradigm, and post-event attentional bias to negative information was assessed using the dot-probe task. Participants then completed a week-long intrusions diary. RESULTS Results showed that attentional bias to negative information mediated the effect of heightened trait anxiety on elevated intrusion frequency. It was also revealed that heightened trait anxiety was associated with elevated intrusion-related distress, though attentional bias to negative information did not mediate this relationship. LIMITATIONS Our sample was comprised of undergraduate students who were not selected based on a previous pathology. Replication in clinical samples is warranted. CONCLUSIONS These findings provide new insight regarding individual differences in the experience of intrusions and suggest that both the frequency and distress associated with intrusions could represent clinical targets.

Neighborhood Socioeconomic Disadvantage and the Neurobiology of Uncertainty in Traumatically Injured Adults. BIOLOGICAL PSYCHIATRY GLOBAL OPEN SCIENCE 2022; 2:263-272.

Abstract
BACKGROUND Individuals residing in more socioeconomically disadvantaged neighborhoods experience greater uncertainty through insecurity of basic needs such as food, employment, and housing, compared with more advantaged neighborhoods. Although the neurobiology of uncertainty has been less frequently examined in relation to neighborhood disadvantage, there is evidence that neighborhood disadvantage is associated with widespread neural alterations. METHODS Recently traumatically injured participants (n = 90) completed a picture anticipation task in the magnetic resonance imaging scanner, in which they viewed images presented in a temporally predictable or unpredictable manner. We investigated how neighborhood disadvantage (via area deprivation index [ADI]) was related to neural activation during anticipation and presentation of negative and neutral images after accounting for individual factors (i.e., age, gender, income, acute posttraumatic stress symptoms). RESULTS There was a significant interaction during the anticipation period such that higher ADI rankings were related to greater activation of the right anterior cingulate cortex to predictable versus unpredictable neutral stimuli. Although no other robust interactions emerged related to ADI, we note several novel simple effects of ADI during anticipation and presentation periods in the hippocampus and prefrontal, cingulate, and occipital cortices. CONCLUSIONS Together, these results may represent an adaptive response to predictable and/or negative stimuli, stemming from chronic exposure to socioeconomic-based uncertainties. Although effects were modest, future work should continue to examine pretrauma context on posttrauma outcomes. To better understand trauma outcomes, it is imperative that researchers consider the broader context in which trauma survivors reside.

Abstract
BACKGROUND AND OBJECTIVES Intrusive re-experiencing of negative events represents a key vulnerability factor for Post-Traumatic Stress Disorder. Thus, delineating attentional mechanisms that might contribute to key facets of intrusive re-experiencing would be highly advantageous. The present study sought to evaluate the novel hypothesis that biased attentional engagement and disengagement differentially contribute to two central facets of intrusive re-experiencing, frequency and controllability, respectively. METHODS One hundred undergraduates were exposed to an acutely negative event, followed by completion of an attentional task that permitted the discrete assessment of biased attentional engagement with, and biased attentional disengagement from, negative vs. non-negative information. Intrusions concerning this negative event were assessed daily, for the subsequent seven days, by means of an electronic diary. RESULTS Results revealed that enhanced attentional engagement with negative vs. non-negative information predicted unique variance in intrusion frequency, whereas impaired attentional disengagement from negative vs. non-negative information predicted unique variance in intrusion controllability. These intrusion-linked patterns of attentional selectivity were evident at shorter (500 ms) stimulus exposure durations only, and not at longer (1000 ms) stimulus exposure durations. LIMITATIONS The current study did not assess attentional selectivity prior to the negative event. Additionally, a time-based approach, rather than an event-based approach, was employed in the assessment of intrusions. CONCLUSIONS The current findings suggest that engagement bias and disengagement bias may underpin differing facets of intrusive re-experiencing, raising the possibility that therapeutically targeting each type of attentional bias may attenuate a distinctive aspect of intrusive re-experiencing.

Abstract
Post-traumatic stress symptoms (PTSSs) have been a common negative psychological response during the COVID-19 pandemic. Previous theories emphasized the unique effects of cognitive and family factors on PTSSs and overlooked their combined role, which suggested that the mechanisms underlying PTSSs were not fully understood. To fill this gap, this study aimed to examine the associations between attention to negative information, blaming others, parent-child relationship and PTSSs, as well as the combined role of these factors on PTSSs. During the COVID-19 pandemic, 1153 college students completed self-report questionnaires. Results indicated that attention to negative information increased PTSSs, both directly and via blaming others. Moreover, parent-child relationship buffered both the exacerbating effect of attention to negative information on blaming others and the effect of blaming others on worsening PTSSs. The current study integrates existing theories, expands the field of trauma research through considering the effect of cognitive and family factors on PTSSs, and provides theoretical support for interventions to relieve PTSSs.

Abstract
BACKGROUND Previous work has indicated that differences in neurocognitive functioning may predict the development of adverse post-traumatic neuropsychiatric sequelae (APNS). Such differences may be vulnerability factors or simply correlates of APNS-related symptoms. Longitudinal studies that measure neurocognitive functioning at the time of trauma are needed to determine whether such differences precede the development of APNS. METHODS Here, we present findings from a subsample of 666 ambulatory patients from the AURORA (Advancing Understanding of RecOvery afteR trumA) study. All patients presented to EDs after a motor vehicle collision (MVC). We examined associations of neurocognitive test performance shortly after MVC with peritraumatic symptoms in the ED and APNS (depression, post-traumatic stress, post-concussive symptoms, and pain) 2 weeks and 8 weeks later. Neurocognitive tests assessed processing speed, attention, verbal reasoning, memory, and social perception. RESULTS Distress in the ED was associated with poorer processing speed and short-term memory. Poorer short-term memory was also associated with depression at 2 weeks post-MVC, even after controlling for peritraumatic distress. Finally, higher vocabulary scores were associated with pain 2 weeks post-MVC. LIMITATIONS Self-selection biases among those who present to the ED and enroll in the study limit generalizability. Also, it is not clear whether observed neurocognitive differences predate MVC exposure or arise in the immediate aftermath of MVC exposure. CONCLUSIONS Our results suggest that processing speed and short-term memory may be useful predictors of trauma-related characteristics and the development of some APNS, making such measures clinically-relevant for identifying at-risk individuals.

Abstract
The aim of the present study was to investigate the role of cognitive processing biases in Type 2 diabetes (T2D) and chronic pain, 2 conditions that are highly co-morbid. The final sample comprised 333 individuals (86 with T2D and chronic pain, 65 with chronic pain, 76 with T2D, 106 without any form of diabetes or pain). Participants completed questionnaires assessing pain and diabetes-related outcomes, as well as measures of interpretation bias, attentional bias, and attentional bias variability. In a 2 (pain status) x 2 (T2D status) x 3 (bias valence) ANOVA design, interpretation biases were found to be stronger in individuals with chronic pain than individuals without pain, although there were no differences according to T2D status. No group differences in attentional biases were found. Among individuals with T2D, greater interpretation bias was associated with better blood glucose control, but also greater fear of hypoglycemia. For individuals with chronic pain, greater interpretation bias and attentional bias variability was associated with worse pain outcomes. Whilst interpretation bias may be present in chronic pain, it also appears to indicate better glycemic control in individuals with T2D. These findings suggest a more dynamic approach to understanding cognitive bias is needed, to consider when these biases are more or less adaptive, so that they can be better harnessed to improve outcomes for individuals with T2D who experience chronic pain. PERSPECTIVE: These findings suggest that cognitive biases can be associated with psychopathology in chronic pain and in T2D, but can also potentially be adaptive in those with T2D. Diabetes management interventions may require a careful balance between promoting sufficient concern to motivate engagement in adaptive diabetes self-management, whilst also minimizing fear of hypoglycemia.

Abstract
BACKGROUND The coronavirus disease 2019 (COVID-19) pandemic has affected college students' mental health and caused post-traumatic stress symptoms (PTSS). Event centrality is thought to play a key role in the development of PTSS, but it is not yet clear by what mechanism. Theoretically, event centrality may affect the retrieval of traumatic memories and further prompt post-traumatic cognitions to understand events, and so may in turn be associated with PTSS in college students. However, few empirical studies have examined the mediating role of post-traumatic cognitions in the relationship between event centrality and PTSS, especially among college students during the COVID-19 pandemic. OBJECTIVES The objective of this study was to examine the mediating roles of post-traumatic cognitive factors (e.g. attention to negative information, catastrophizing, and rumination) in the relationship between event centrality and PTSS among college students during the COVID-19 pandemic. METHODS We recruited 1153 college students who completed the pandemic experiences scale, the centrality of event scale, the attention to positive and negative information scale, the cognitive emotion regulation questionnaire, and the PTSD Checklist for DSM-5 during the COVID-19 pandemic in May 2020. RESULTS In this sample of college students, event centrality directly predicted PTSS, and PTSS was also indirectly predicted by event centrality through attention to negative information, catastrophizing, and rumination. CONCLUSIONS These findings support the existing literature on the relationship between event centrality, proposed cognitive variables, and PTSS, and shed light on the mechanisms underlying PTSS. Our findings also highlight the importance and applicability of targeted cognitive interventions for PTSS in college students during the COVID-19 pandemic. HIGHLIGHTS The COVID-19 pandemic has caused post-traumatic stress symptoms among college students.Event centrality is a risk factor of post-traumatic stress symptoms among college students during the COVID-19 pandemic.Attention to negative information, catastrophizing and rumination mediate the relationship between event centrality and post-traumatic stress symptoms.

Abstract
Emotion regulation and interpersonal psychotherapies that do not require trauma memory processing have been shown to be effective in treating posttraumatic stress disorder (PTSD). This study used a novel method to assess in vivo outcomes in a randomized clinical trial with women (N = 147; ages 18-54; 61% of color; 94% low income) with full (79%) or partial (21%) PTSD. Participants were assigned to affect regulation or interpersonal therapy, or wait-list, and completed daily self-reports for 2 to 4 weeks at baseline and up to 30 days at posttest. Mixed model regression analyses tested pre-post change on five factor analytically derived aggregated daily self-report scores. Emotion regulation-focused therapy was associated with reduced PTSD symptoms, dysregulation, and negative affect, and improvement in adaptive self-regulation and positive affect. Interpersonal-focused therapy was associated with reduced PTSD symptoms and dysregulation. Although both therapies were associated with reduced PTSD symptoms, whether this was due to nonspecific factors rather than the treatments per se could not be determined. Daily self-report data warrant further investigation in psychotherapy research with disorders such as PTSD, in order to assess affective and interpersonal dysregulation and adaptive regulation as they occur in daily life.

Abstract
Background Post-Traumatic Stress Disorder (PTSD) symptoms include re-experiencing, avoidance, hyperarousal, and cognitive deficits, reflecting both emotional and cognitive dysregulation. In recent years, non-pharmacological approaches and specifically animal-assisted therapy have been shown to be beneficial for a variety of disorders such as Attention-Deficit/Hyperactivity Disorder, Autism Spectrum Disorder, and PTSD. However, little is mentioned in the literature about the reciprocal effects of the animal-human interaction. Objective To evaluate the effects of a one-year dog training programme on PTSD symptomatology in youngsters with PTSD and on dogs' behaviour. Methods Fifty-three adolescents, previously exposed to interpersonal trauma, were clinically diagnosed with PTSD and assigned to a dog-training programme group (n = 30) and a control group (n = 23) that engaged in other training programmes (e.g. cooking, hairstyling, etc.). Both groups were evaluated at baseline and following 12-months by The Clinician-Administered PTSD Scale for DSM-5 in Children and Adolescents (CAPS-CA-5) and Beck-Depression Inventory (BDI). Additionally, we physiologically measured both emotional and attention dysregulation. Results Post-12-months training, a significant alleviation of PTSD symptomatology accompanied by lower depression severity was observed in the dog-training group, compared with a insignificant recovery in the control group. Furthermore, improved emotional and attentional regulation was observed in the dog-training group. Measuring the dogs' behaviour revealed increased anxiety and decreased selective attention performance, which was inversely correlated with the beneficial effects observed in the dog-training programme group. Conclusions Our findings emphasize the role of emotional and attentional regulations on the dog-handler interface, as evidence-based support for the beneficial effects of the dog-training programme, as either a non-pharmacological intervention or as complementary to anti-depressants treatment of PTSD. Though pharmacological treatments increase the patients' well-being by treating certain PTSD symptoms, our suggested dog-training programme seems to influence the PTSD diagnostic status, thus may be implemented in civilians and veterans with PTSD.

Abstract
Whilst people with high contamination fear may not experience a greater number of contamination-related intrusions than people with low contamination fear, they tend to experience heightened distress in response to such intrusions. The aim of the present study was to test the hypothesis that attentional bias to contamination-relevant information, and the variability of this attentional bias, moderates the degree to which high contamination fearful but not low contamination fearful individuals experience distress in response to contamination-related intrusions. Individuals with high (n = 31) or low (n = 44) contamination fear completed a lab-based session including questionnaires, a dot-probe measure of contamination-related attentional bias and attentional bias variability, and a contamination stressor video. Participants then completed a week-long contamination intrusions diary. There were significant differences in intrusion distress between those with low and high contamination fear in the anticipated direction, and attentional bias significantly moderated this relationship. Regardless of contamination fear level, greater attentional bias variability was associated with greater intrusion distress. These findings suggest that reducing attentional bias variability could potentially help to reduce distress elicited by contamination-related intrusions, while also highlighting the fact that attentional bias towards threat may protect against such distress in low contamination fearful individuals.

Examining the potential roles of attention control and response time variability in its relationship with anxiety. Behav Res Ther 2020; 135:103751.

Abstract
The present study examined the underlying role of attention control and response time variability in explaining the relationship between anxiety and two commonly computed measures of attention bias variability: 'moving average' and 'trial-level bias score' measures. Participants (final n = 195) completed measures of anxiety symptomatology, antisaccade performance (attention control), a stand-alone measure of response-time variability, and a probe task measure of attention bias. Average bias and moving average bias variability measures both recorded significant, but low split-half reliability. Both attention bias variability measures and average attention bias were associated with anxiety, and attention control. Both attention bias variability measures correlated with response time variability. Neither attention bias variability measure correlated with average attention bias. Attention control was the single significant mediator of the relationship between anxiety and the trial-level bias score measure of attention bias variability. Neither response time variability nor attention control significantly mediated the relationship between anxiety and the moving average measure of attention bias variability. No evidence was found for the mediating role of response time variability. The present findings suggest that the relationships observed between anxiety and the trial-level bias score measure of attention bias variability in particular may be attributable to the over-arching role of attention control.

Abstract
Oral-Self Implemented HIV Testing (Oral-SIT) offers a low-cost way to extend the reach of HIV testing systems. It is unclear, however, if high risk populations are able to perform the test with high fidelity. Using a simulation-based research design, we administered desensitized Oral-SIT kits to African American MSM (AAMSM; 17-24 years, N = 178). Participants were HIV negative or never tested, and had never self-administered an Oral-SIT kit. We assessed performance fidelity, and hypothesized antecedents. High levels of social stigma were associated with lower levels of training knowledge (Range = No Errors: 51.9%, 4 Errors: 0.6%) and performance fidelity (Range = No Errors: 39.9%, 3 Errors: 1.7%). Training knowledge and prior testing history were positively associated with performance fidelity. The present work extends research on HIV-related social stigma and suggests that social stigma inhibits knowledge acquisition and task performance. The Oral-SIT training materials were understood by individuals with a wide-range of educational backgrounds. Interventions are needed, however, to further improve Oral-SIT performance fidelity.

Attentional bias and its temporal dynamics among war veterans suffering from chronic pain: Investigating the contribution of post-traumatic stress symptoms. J Anxiety Disord 2019; 66:102115.

Abstract
BACKGROUND Cognitive models propose that attentional dysregulation, including an attentional bias towards threat, is one of the factors through which chronic pain and post-traumatic stress symptoms (PTSS) maintain and exacerbate one another. The current investigation assessed the attentional bias for painful facial expressions and its relationship with PTSS, using both traditional and variability-based attentional bias measures, among veterans with chronic pain and PTSS and controls. METHOD Fifty-four veterans with chronic pain and 30 age/education-matched controls participated in this investigation. Participants completed a self-report measure of PTSS and a modified version of the dot-probe task with painful, happy, and neutral facial expressions. Attention was assessed using both traditional and variability-based reaction time measures of attentional bias. RESULTS Veterans directed attention away from painful facial expressions (i.e., avoidance) relative to both the control group (between-subject effect) and relative to neutral faces (within-subject effect). Veterans also showed significantly elevated attentional bias variability for both happy and painful facial expressions compared to controls. Attentional bias variability for happy and painful facial expressions was correlated with PTSS among all participants. CONCLUSION Veterans with chronic pain and PTSS avoided pain-related stimuli and displayed an overall attentional dysregulation for emotional facial expressions. Avoidance of pain cues may be a coping strategy that these individuals develop under stressful conditions. Implications, limitations, and directions for future research are discussed.

Abstract
Intrusive memories of a traumatic event can be distressing and disruptive, and comprise a core clinical feature of post-traumatic stress disorder (PTSD). Intrusive memories involve mental imagery-based impressions that intrude into mind involuntarily, and are emotional. Here we consider how recent advances in cognitive science have fueled our understanding of the development and possible treatment of intrusive memories of trauma. We conducted a systematic literature search in PubMed, selecting articles published from 2008 to 2018 that used the terms "trauma" AND ("intrusive memories" OR "involuntary memories") in their abstract or title. First, we discuss studies that investigated internal (neural, hormonal, psychophysiological, and cognitive) processes that contribute to intrusive memory development. Second, we discuss studies that targeted these processes using behavioural/pharmacological interventions to reduce intrusive memories. Third, we consider possible clinical implications of this work and highlight some emerging research avenues for treatment and prevention, supplemented by new data to examine some unanswered questions. In conclusion, we raise the possibility that intrusive memories comprise an alternative, possibly more focused, target in translational research endeavours, rather than only targeting overall symptoms of disorders such as PTSD. If so, relatively simple approaches could help to address the need for easy-to-deliver, widely-scalable trauma interventions.
