Anxiety-related attentional biases and their regulation by attentional control

Examining attentional avoidance in post-traumatic stress disorder: an exploratory 'Face in the Crowd' paradigm using eye-tracking

Background: Maladaptive patterns of attention to emotional stimuli are a clinical feature of posttraumatic stress disorder (PTSD). Using eye-tracking-based methodology, research points out the presence of sustained attention to threatening stimuli in individuals with PTSD. However, most eye-tracking studies in this field used free-viewing tasks on negative stimuli.Methods: PTSD patients (n = 38), trauma-exposed healthy controls (TEHC; n = 30), and non-trauma-exposed healthy controls (HC; n = 33) performed a Face in the Crowd (FiC) task. The FiC task was chosen to explore specific responses to emotional stimuli within a competitive visual environment, thus providing insights into visual search patterns. Both reaction time and gaze patterns (dwell time, scanpath length, first fixation duration, and latency) were recorded.Results: Individuals with a provisional PTSD diagnosis presented decreased dwell time on both positive and negative targets in comparison with HC and TEHC, as well as shorter scanpath length for all matrixes when no targets were present. No evidence of attentional bias was observed in the TEHC group based on reaction times or eye-tracking measures in response to positive, negative, or neutral cues.Discussion: We found an attentional avoidance pattern among PTSD patients, along with indexes of lowered perceptual threshold for all emotional information. This study allows raising the question of cognitive load on the emergence of differential attentional strategies presented by PTSD participants. We discuss the generalization of fear processes across different emotional stimuli and underscore the need for incorporating a variety of emotional stimuli in PTSD research.

Why is rumination unhelpful in adolescents? Two studies examining the causal role of abstract processing

Rumination is a common feature of depression in adolescents and adults and it is implicated in the maintenance of depression symptoms. In adults, the maladaptive consequences of rumination have been attributed to the abstract processing mode that characterises this thinking style. The question of whether the same is true in adolescents remains unanswered. Here we describe two experimental studies in which adolescents were trained to think in a mode either characteristic of or inconsistent with the abstract processing style observed in depressive rumination, and the effect on social problem-solving and negative future thinking was examined. The two experiments employed a similar design. 11-14 year olds scoring in the upper and lower quartile on a measure of depression were trained to engage in an abstract or concrete processing style and then carry out a social problem-solving (Study 1) or future thinking (Study 2) task. Adolescents were worse at social problem-solving and had more negative (but not fewer positive) future thoughts when engaging in abstract processing compared to concrete processing, regardless of their current level of depressive symptoms. The finding remained when controlling for state mood. Our findings suggest there may be value in targeting abstract ruminative processing as an early treatment for depression.

Trait anxiety predicting the developmental trajectories of depression symptoms in children: The mediating role of attentional control

Trait anxiety and attentional control are important factors related to depression symptoms. The study investigated how trait anxiety and attentional control predicted the trajectories of depression symptoms during the transition into early adolescence. The mediating effect of attentional control on the relationship of trait anxiety to the trajectories of depression symptoms was also examined. Children of 9 to 10 years were recruited at Time 1. Trait anxiety, attentional control, and depression symptoms were assessed at Time 1. Depression symptoms were measured at three follow-up assessments across 18 months. Latent class growth modeling revealed high (14.4%) and low (85.6%) trajectories of depression symptoms. Higher trait anxiety and lower attentional control predicted a higher likelihood of showing the trajectory of high depressive symptoms. Attentional control mediated the relationship of trait anxiety to the trajectory membership of depression symptoms. The findings had important implications for the association of trait anxiety with the trajectory membership of depression symptoms and highlighted the importance of attentional control in the development of depression symptoms for children with high trait anxiety.

Feasibility Testing a Meditation App for Professionals Working With Youth in the Legal System: Protocol for a Hybrid Type 2 Effectiveness-Implementation Pilot Randomized Controlled Trial

BACKGROUND

Probation officers and other professionals who work with youth in the legal system often experience high chronic workplace stress, which can contribute over time to elevations in anxiety, depression, and workplace burnout. Emotion dysregulation appears to function as a common mechanism underlying these elevations, and growing evidence suggests it can be improved with mindfulness meditation. Implemented successfully, app-based meditation programs could provide professionals with real-time tools for mitigating the effects of chronic workplace stress.

OBJECTIVE

This paper describes the protocol for a hybrid type 2 effectiveness-implementation pilot randomized controlled trial (RCT) of Bodhi AIM+, a meditation app adapted with and for professionals who work with youth in the legal system. The adaptation process and implementation plan, as well as the pilot RCT design, were guided by theoretically driven implementation science frameworks. The primary outcome of the pilot RCT is app adherence (ie, ongoing app usage per objective analytics data).

METHODS

The RCT will be fully remote. Officers and other professionals who work with youth in the legal system (N=50) will be individually randomized to use the meditation app or an active control app matched for time and structure. All participants will be asked to follow a 30-day path of brief audio- or video-guided content and invited to use additional app features as desired. In-app analytics will capture the objective usage of each feature. An adaptive engagement design will be employed to engage nonusers of both apps, whereby analytics data indicating nonuse will trigger additional support (eg, text messages promoting engagement). Mental health outcomes and potential moderators and covariates will be self-reported at baseline, posttest, and 6 months. Participants will also complete 1-week bursts of ecological momentary assessment (EMA) at baseline and over the last week of the intervention to capture the mechanistic target (ie, emotion regulation) in real time. All participants will be invited to complete qualitative posttest interviews. Descriptive statistics will be calculated for quantitative data. Qualitative data will be analyzed using a combined deductive-inductive approach. The quantitative and qualitative data will be incorporated into a mixed methods triangulation design, allowing for the evaluation of app adherence and other implementation outcomes as well as related barriers and facilitators to implementation.

RESULTS

Enrollment into the trial started in December 2024 and is currently underway. Study results are anticipated to be available in 2026.

CONCLUSIONS

Completion of this pilot trial will inform a future, fully powered RCT to formally evaluate the effectiveness and implementation of Bodhi AIM+. Its use of implementation science methods, coupled with digital technology, positions the present study not only to help make meditation tools available to an important workforce at scale but also to inform broader efforts at implementing and evaluating health apps within workplace settings.

Attention and spatial navigation in everyday life: Physical activity is associated with subjective aspects of cognitive function

Efforts to understand the effects of physical activity on cognitive health have long relied on employing objective measures that assess the efficacy of the mechanics of cognition. However, this perspective overlooks complementary dimensions of cognitive functioning, namely one's subjective appraisal of the efficacy of their cognitive mechanics. In a set of four investigations (N =  2965), we sought to discern whether physical activity (PA), and other health and demographic factors, contribute to subjective experiences of cognitive mechanics (SCF) and to map for future investigations domains of function that are sensitive to health factors. We employed linear multiple regression analyses to examine survey data collected online from four large samples of young adults who responded to measures of health behaviours and SCF. PA contributed to subjective experiences of attentional control and spatial navigation but not memory, executive function, or general cognitive functioning. Further, sleep, diet, and stress were each consistently associated with selective measures of subjective experiences of cognition. Taken together, these studies indicate the importance of PA, as well as additional health behaviours, as significant contributors to SCF.

Modeling Factors Associated With Academic Procrastination in University Students

It is known that academic procrastination is a widespread problem among college students, which significantly reduces their academic performance and quality of life. This study aims to examine the relationship between the academic procrastination behavior of university students and nomophobia, netlessphobia, academic self-efficacy, self-regulation, and attentional control. This study was planned in a correlational survey model. Between October 2023 and February 2024, 528 students studying at a state university participated in the study. Structural equation modeling was used to analyze the research data. According to the results of the study, nomophobia, netlessphobia, academic self-efficacy, and attentional control of self-regulation variables together can explain 23% of the variance in academic procrastination (R2 = .23). In the model, the variable that has the greatest effect on academic procrastination is attentional control of self-regulation. As the level of academic self-efficacy increases, the level of academic procrastination decreases. As the level of nomophobia and netlessphobia increases, the level of academic procrastination also increases. It is believed that the results of this study can be used in preparing programs to reduce or prevent academic procrastination behavior for university students in the future.

Attentional control dampens the effects of intolerance of uncertainty and uncertainty-related attentional bias on posttraumatic stress symptoms

Intolerance of uncertainty (IU) is a risk factor for posttraumatic stress symptoms (PTSS) following trauma, and attentional biases for uncertainty stimuli (ABU) may be as well. Evidence suggests that better attentional control protects individuals who are vulnerable to several forms of psychopathology from developing such pathology. However, to our knowledge, the potential buffering effect of attentional control in relations between IU, ABU, and PTSS has yet to be examined. In the present study, 125 trauma-exposed undergraduate participants completed a battery of self-report measures and an eye-tracking visual-search task to assess ABU. The sample was primarily White (88.80%) and female (83.2%) with an average age of 19.70 years (SD = 2.60). A series of hierarchical regressions demonstrated that elevated IU and difficulties disengaging from uncertainty stimuli were associated with higher PTSS, but only among participants with lower scores on a measure of attentional control. For participants with relatively better attentional control, the associations between IU, ABU, and PTSS were non-significant. The non-clinical nature and relative homogeny of the current sample may limit generalizability of results, which warrant replication. Attentional control may protect trauma-exposed individuals from the negative effects of IU and ABU on PTSS.

A meta-analysis on the relationship between subjective cognitive failures as measured by the cognitive failures questionnaire (CFQ) and objective performance on executive function tasks

The Cognitive Failures Questionnaire (CFQ) has been widely used as a measure of subjective cognitive function in everyday life for decades. However, the evidence on how it relates to objective performance on executive function tasks is mixed. One possible reason for these mixed results is that the CFQ has selective relationships with some aspects of executive function and not others. Here, therefore, we classified tasks according to an influential framework of executive functions-switching, updating, inhibition, and we also considered the Sustained Attention to Response Task (SART) as a category because it was custom designed to gauge cognitive failures. We synthesized a large body of available evidence and performed four Bayesian meta-analyses on the relationship between CFQ scores and objective performance on executive function tasks in these four categories. Results suggested that CFQ scores were associated with objective performance on SART (18 effect sizes, μ = -.19, BF10 = 18.03, i.e., 18.03 times more evidence of a relationship versus no relationship), updating working memory (49 effect sizes, μ = -.06, BF10 = 17.80), and inhibition tasks (41 effect sizes, μ = -.07, BF10 = 15.40), whereas there was not definitive evidence regarding switching (34 effect sizes, μ = -.06, BF10 = .50, i.e., two times greater evidence for no relationship). This suggests that subjective cognitive function can predict objective performance on at least some executive function tasks. We discuss methodological and theoretical factors that constrain the maximum observable correlation and consider the relative insights that subjective measures versus task performance provide.

A temporal investigation of the relationship between difficulty concentrating and perseverative thought

Perseverative thought (also known as repetitive thought) is an established transdiagnostic mechanism of internalizing psychopathology characterized primarily by its repetitive, difficult to control quality. Subjective difficulty concentrating frequently coincides with perseverative thought and may function as both mechanism and clinical consequence of perseverative thought. Although cognitive theories suggest a bidirectional relationship between perseverative thought and difficulty concentrating, experimental and longitudinal investigations provide mixed evidence. The current study addresses this gap by testing a bidirectional relationship between momentary perseverative thought and difficulty concentrating using ecological momentary assessment (EMA) (8 surveys per day for 14 days) with 200 adult community participants (N = 155 with compliance ≥ 70 %) oversampled for moderate/severe perseverative thought. Multilevel modeling tested concurrent and time-lagged associations. Difficulty concentrating and perseverative thought were concurrently and prospectively related within-person: higher difficulty concentrating at T-1 predicted higher perseverative thought at T, and higher perseverative thought at T-1 predicted higher difficulty concentrating at T (β =.19 -.20, p < .001). Findings held when controlling for the outcome at T-1 (β =.02 - .06, p < .001). These findings demonstrate covariation between difficulty concentrating and perseverative thought within-person in daily life consistent with theoretical models that predict bidirectional relationships. Findings suggest that intervening on difficulty concentrating and/or perseverative thought may reduce the "vicious cycle" of perseverative thought episodes.

Attentional biases for dynamic stimuli in emerging adults with anxiety: A preliminary eye-tracking study

While attentional biases towards negative stimuli have previously been linked to the development and maintenance of anxiety disorders, a current limitation of this research involves the use of static images for stimuli, as they cannot adequately depict the dynamic nature of real-life interactions. Since attentional biases in those with elevated anxiety remain understudied using more naturalistic stimuli, such as dynamic social videos, the purpose of this explorative study was to use novel dynamic stimuli and modern eye-tracking equipment to further investigate negative attentional biases in anxious emerging, female adults. Non-clinical participants (N = 62; mean age = 20.44 years; biologically female) completed validated questionnaires regarding their anxiety symptoms and completed a free-viewing task by watching 30-s video clips while having their eye movements tracked. The video clips were shown in side-by-side pairs (i.e., positive-neutral, negative-neutral, and positive-negative) on a split screen without audio. Overall, participants fixated more quickly on emotional videos (i.e., positive and negative) over neutral ones, with more anxious participants orienting their gaze faster to the videos, regardless of content. Moreover, individuals with greater self-reported anxiety spent more time gazing at negative videos in negative-neutral pairings, highlighting that emerging female adults with increased anxiety symptoms may show a negative attention bias when viewing social interactions. Importantly, by incorporating novel, dynamic stimuli, we expand upon prior research on attentional biases, with the potential to adapt this approach for novel interventions that may ultimately help those suffering from anxiety.

Mediating attentional control between depression and problematic Internet use in female adolescents: the role of attentional focusing and shifting

PURPOSE

Female adolescents are more prone to depression compared with male adolescents, and depression is often associated with poor attentional control and problematic internet use (PIU). Attentional control includes both focusing and shifting functions. Focusing refers to the ability to direct attention to a task despite distractions. Shifting refers to the ability to flexibly switch attention between different tasks. This study examines the mediating role of attentional focusing and shifting between depression and PIU.

METHODS

Female high school and college students (n = 476) in Taiwan participated in a survey administered at three time points over a seven-month period. The single- and two- mediator models examined their joint mediation effects.

RESULTS

The results showed that the direct effect of depression on PIU was significant. The indirect effects also showed that attentional focusing was a negative partial mediator in the relationship between depression and PIU, while attentional shifting was not one.

CONCLUSION

Informed by attentional theory and digital emotion regulation, addressing depression to mitigate its negative impact on attentional control and negative emotions is crucial. The potential impact, whether harmful or beneficial, of adolescents carefully selecting their online activities to reduce the risk of PIU remains contentious. Given the focus on Taiwanese adolescent girls during the COVID-19 pandemic, further research is needed to extend the applicability of the theory to other periods without being affected by COVID-19.

Latent profile analysis of operating room nurses' occupational fatigue and its relationship with attentional control

BACKGROUND

Occupational fatigue in operating room nurses may influence their attentional control. However, few previous studies have explored the correlation between occupational fatigue and attentional control in operating room nurses. To better understand operating room nurses' occupational fatigue and its relationship with attentional control, this study aimed to identify the latent profiles and their factors that influence operating room nurses' occupational fatigue as well as differences in attentional control across each latent profile.

METHODS

A cross-sectional study was conducted from May 2024 to July 2024, and a total of 386 operating room nurses were recruited from 6 hospitals in Chengdu. The participants completed the Occupational Fatigue Scale and the Attentional Control Scale. Latent profile analysis (LPA) was employed to identify latent profiles of occupational fatigue among operating room nurses. The predictors of occupational fatigue in different latent profiles were assessed via multinomial logistic regression analysis. One-way ANOVA and the Kruskal-Wallis test were used to compare the scores on the attentional control scale for each latent profile of nurses' occupational fatigue.

RESULTS

This study identified three latent profiles of operating room nurses'. occupational fatigue: the "low-fatigue/high-recovery group" (n = 80, 21.2%), the "high-fatigue/low-recovery group" (n = 113,29.3%) and the "moderate-fatigue/mod-erate-recovery group" (n = 193, 49.4%). The results of the multinomial logistic regression analysis suggested that age, work experience, educational level and monthly income were predictors of operating room nurses' occupational fatigue. There were significant differences in attentional control among the different pr-ofiles of occupational fatigue (P < 0.001). The scores for attentional focus were. Significantly different across each profile (P < 0.001), whereas the scores for at-tentional shift were not different across profiles (P = 0.342).

CONCLUSIONS

Operating room nurses' occupational fatigue can be divided into three latent profiles. Reducing chronic and acute fatigue while enhancing intershift recovery can improve nurses' attentional control and improve the overall service quality of the hospital. Nursing managers should identify operating room nurses who are at risk and implement targeted interventions to reduce occupational fatigue.

TRIAL REGISTRATION

This study does not involve clinical trials or interventional procedures and therefore does not meet the criteria for clinical trial registration.

Can HRV Biofeedback Training Improve the Mental Resilience of Icelandic Police Officers?

High heart rate variability (HRV) is increasingly recognized as an indicator of a healthy regulatory system, reflecting the dynamic balance between sympathetic (SNS) and parasympathetic (PSNS) nervous system activity. According to the neurovisceral integration model, this balance is managed by the central autonomic network (CAN), comprised of specific brain regions involved in emotional, attentional, and autonomic regulation. HRV thus reflects the performance of the cognitive, affective, and autonomic regulation system. Numerous studies support the relationship between HRV and the CAN, including research on HRV biofeedback training (HRVBF). Studies on the effectiveness of HRVBF for professions such as police officers have shown improvements in self-regulation, decision-making, and performance. However, few studies have specifically explored HRVBF's influence on HRV metrics in police officers, highlighting a need for further research. This study addresses this gap by randomly assigning 27 Icelandic police officers to intervention or wait-list control groups. The intervention group underwent a five-week HRVBF program, including group and individual training sessions. Results showed significant increases in HRV metrics for the intervention group, indicating improved autonomic function and stress resilience. Mental resilience increased significantly as measured by subjective measures of attentional control, mindful awareness, and reduced fatigue. These findings support the efficacy of HRVBF in enhancing HRV and mental resilience for police officers, suggesting its applicability and potential for integration into existing training programs.

Attend to the positive while feeling anxious: The effect of state anxiety on the effectiveness of Attentional Bias Modification

BACKGROUND AND OBJECTIVES

Elevating state anxiety during Attentional Bias Modification (ABM) may improve its effectiveness by matching the emotional state experienced during the training with the emotional state under which it is intended that the learned pattern of attentional bias will subsequently operate. This study examined whether inducing elevated levels of state anxiety during ABM enhanced the effectiveness in modifying an attentional bias to socially threatening information.

METHODS

Participants (n = 160) were randomized to a single session of attend-negative or attend-positive dot-probe training which was interspersed with either a state anxiety induction or control condition. Attentional bias was assessed post-training by means of a dot-probe task and a visual search task.

RESULTS

ABM was effective in modifying attentional bias in the direction of the allocated training condition as assessed with a dot-probe task, but did not generalize to a visual search task. Importantly, state anxiety did not moderate ABM's training effects.

LIMITATIONS

Although the state anxiety manipulation successfully induced state anxiety, state anxiety levels were modest which potentially limited the chance to detect a moderating effect of state anxiety.

CONCLUSIONS

Although these findings suggest that inducing state anxiety during ABM does not improve its effectiveness, more studies are needed to confirm this preliminary conclusion. Future studies should examine whether larger state anxiety elevations and state anxiety manipulations that are more integrated into the ABM procedure do enhance training effects.

Efficacy of traditional and gamified attention bias modification for depression: Study protocol for a randomized controlled trial

Cognitive models posit that negatively biased attention toward dysphoric information has a causal role in the maintenance of depression-related psychopathology. Attention bias modification (ABM) tests this idea by altering an attentional bias and examining subsequent effects on depression. Prior work finds that ABM alters negatively biased attention for dysphoric information and reduces depression; however, a number of studies have failed to show these effects. Other research suggests that adding game-like elements (i.e.game play, achievements, levels, challenges, and points) to cognitive training can enhance participant engagement. No prior work has examined the efficacy of gamified ABM for depression. The goal of this study is to conduct a large (N = 600) efficacy trial comparing gamified, mobile ABM and traditional, web-based ABM to traditional, web-based sham ABM among adults with elevated symptoms of depression. Participants in all conditions are asked to complete 16 ABM sessions across a four week period (i.e., 4 training sessions per week). We hypothesize that gamified and traditional ABM will lead to significantly greater reductions in self-reported and interviewer-rated depression symptoms than traditional sham ABM. We further hypothesize that gamified ABM will be non-inferior to traditional ABM. Our third hypothesis is that people with a strong attentional bias will experience greater reductions in depression in response to either gamified or traditional ABM compared to sham ABM. Secondary analyses will examine putative mediators of ABM. Finally, we will estimate the durability of ABM by collecting post-treatment symptom data 2-, 3-, and 6-months after the acute ABM period.

Reels to Remembrance: Attention Partially Mediates the Relationship Between Short-Form Video Addiction and Memory Function Among Youth

Background and Purpose: The proliferation of short-form video content on social media platforms has led to increased user engagement but also raised concerns about potential addictive behaviors and cognitive consequences, particularly among youth. This study explored the prevalence of short-form video addiction (SVA) among Jordanian youth, its correlates, and its impact on attention and memory function, with an emphasis on understanding the mediating and moderating role of attention in the relationship between SVA and memory. Methods: Utilizing a cross-sectional survey design, data were collected from 1029 university students across 25 higher-education institutions in Jordan. Results: Half of the participants exhibited moderate to high levels of SVA. The findings indicated a significant increase in SVA scores among female students (p = 0.003), those of a younger age (p = 0.045), those with lower GPAs (p = 0.013), and those who dedicated fewer hours to study (p = 0.006). Notably, there was a significant and large correlation between SVA scores and students' perceptions of user-generated content (p < 0.001). Attention partially mediated the relationship between SVA and memory function with excellent model fit indices (χ2(12) = 14.11, p = 0.05, RMSEA = 0.03, GFI = 0.99, IFI = 0.99, TLI = 0.98, CFI = 0.99). However, attention did not moderate this relationship, suggesting that the impact of SVA on memory is consistent across varying levels of attention. Discussion: The findings underscore the significant engagement of Jordanian youth with short-form video content and the potential cognitive risks associated with SVA. Interventions to manage attention could mitigate the adverse effects of SVA on cognitive functions. This study calls for a comprehensive approach to address SVA among youth, including the development of digital literacy programs, mental health support services, and policy interventions that promote a balanced digital ecosystem and responsible media consumption.

Gamified Web-Delivered Attentional Bias Modification Training for Adults With Chronic Pain: Randomized, Double-Blind, Placebo-Controlled Trial

BACKGROUND

Attentional bias to pain-related information has been implicated in pain chronicity. To date, research investigating attentional bias modification training (ABMT) procedures in people with chronic pain has found variable success, perhaps because training paradigms are typically repetitive and monotonous, which could negatively affect engagement and adherence. Increasing engagement through the gamification (ie, the use of game elements) of ABMT may provide the opportunity to overcome some of these barriers. However, ABMT studies applied to the chronic pain field have not yet incorporated gamification elements.

OBJECTIVE

This study aimed to investigate the effects of a gamified web-delivered ABMT intervention in a sample of adults with chronic pain via a randomized, double-blind, placebo-controlled trial.

METHODS

A final sample of 129 adults with chronic musculoskeletal pain, recruited from clinical (hospital outpatient waiting list) and nonclinical (wider community) settings, were included in this randomized, double-blind, placebo-controlled, 3-arm trial. Participants were randomly assigned to complete 6 web-based sessions of nongamified standard ABMT (n=43), gamified ABMT (n=41), or a control condition (nongamified sham ABMT; n=45) over a period of 3 weeks. Active ABMT conditions trained attention away from pain-related words. The gamified task included a combination of 5 game elements. Participant outcomes were assessed before training, during training, immediately after training, and at 1-month follow-up. Primary outcomes included self-reported and behavioral engagement, pain intensity, and pain interference. Secondary outcomes included anxiety, depression, cognitive biases, and perceived improvement.

RESULTS

Results of the linear mixed model analyses suggest that across all conditions, there was an overall small to medium decline in self-reported task-related engagement between sessions 1 and 2 (P<.001; Cohen d=0.257; 95% CI 0.13-0.39), sessions 1 and 3 (P<.001; Cohen d=0.368; 95% CI 0.23-0.50), sessions 1 and 4 (P<.001; Cohen d=0.473; 95% CI 0.34-0.61), sessions 1 and 5 (P<.001; Cohen d=0.488; 95% CI 0.35-0.63), and sessions 1 and 6 (P<.001; Cohen d=0.596; 95% CI 0.46-0.73). There was also an overall small decrease in depressive symptoms from baseline to posttraining assessment (P=.007; Cohen d=0.180; 95% CI 0.05-0.31) and in pain intensity (P=.008; Cohen d=0.180; 95% CI 0.05-0.31) and pain interference (P<.001; Cohen d=0.237; 95% CI 0.10-0.37) from baseline to follow-up assessment. However, no differential effects were observed over time between the 3 conditions on measures of engagement, pain intensity, pain interference, attentional bias, anxiety, depression, interpretation bias, or perceived improvement (all P values>.05).

CONCLUSIONS

These findings suggest that gamification, in this context, was not effective at enhancing engagement, and they do not support the widespread clinical use of web-delivered ABMT in treating individuals with chronic musculoskeletal pain. The implications of these findings are discussed, and future directions for research are suggested.

The integration of self-efficacy and response-efficacy in decision making

The belief that we can exert an influence in our environment is dependent on distinct components of perceived control. Here, we investigate the neural representations that differentially code for self-efficacy (belief in successfully executing a behavior) and response-efficacy (belief that the behavior leads to an expected outcome) and how such signals may be integrated to inform decision-making. Participants provided confidence ratings related to executing a behavior (self-efficacy), and the potential for a rewarding outcome (response-efficacy). Computational modeling was used to measure the subjective weight of self-efficacy and response-efficacy while making decisions and to examine the neural mechanisms of perceived control computation. While participants factored in both self-efficacy and response-efficacy during decision-making, we observed that integration of these two components was dependent on neural responses within the vmPFC, OFC and striatum. Further, the dlPFC was observed to assign importance to self-efficacy and response-efficacy in specific trials, while dACC computed the trade-off between both components, taking into account individual differences. These findings highlight the contributions of perceived control components in decision-making, and identify key neural pathways involved in computing perceived control.

Effects of brief mindfulness intervention on mental fatigue and recovery in basketball tactical performance

OBJECTIVE

The detrimental effects of mental fatigue (MF) have been established in sports, such as soccer, volleyball, and basketball. Mindfulness interventions are considered a promising method to help players counteract MF, but whether it could improve basketball tactical performance after MF in competition is not clear. This study aims to investigate the effect of brief mindfulness intervention on basketball tactical performance under MF.

METHOD

This study employed a cluster randomized controlled trial (cRCT) design. It involved 54 male basketball players aged 18 to 24 from three universities. The participants were randomly assigned to one of three groups: control group (CG), mental fatigue group (MFG), and mental fatigue-mindfulness group (MF-MG). Players in the MFG and MF-MG underwent a 30-minute Stroop task to induce MF. Subsequently, players in the MF-MG engaged in a 30-minute audio mindfulness intervention. Basketball tactical performance was assessed in the small side games (SSG).

RESULTS

There were no significant differences in total tactics observed across groups and over time. However, when examining specific tactical sub-variables, significant differences were found in ball reversal, dribble penetration into the key area, and off-ball screen between the CG and MFG in the post-test. Furthermore, significant differences were noted in ball reversal, dribble penetration into the key area, on-ball screen, and off-ball screen between the MFG and MF-MG in the post-test.

CONCLUSION

The basketball tactical performances, particularly in areas such as ball reversal, dribble penetration into the key area, on-ball screen, and off-ball screen, were negatively impacted by MF. Notably, the brief mindfulness intervention effectively restored these performance aspects. This suggests that coaches and trainers should place increased emphasis on players' mental well-being and consider incorporating brief mindfulness interventions into their training programs. More studies that investigate mindfulness intervention on the comprehensive aspects of basketball performance should be focused on in the future.

The Influence of Intolerance of Uncertainty on Social Anxiety in University Students: The Sequential Mediating Effect of Core Self-Evaluation and Attentional Control

Social anxiety is a serious and prevalent psychological problem among university students, with intolerance of uncertainty playing an important role in its formation and development. The underlying mediating processes remain elusive despite the existing research on the association between these two constructs. This investigation developed a sequential mediation model grounded in the triadic reciprocal determinism theory to examine the intermediary roles of core self-evaluation and attentional control. Utilizing a convenience sampling method, a total of 1580 undergraduate students were recruited for this study. The study variables were assessed using scales measuring intolerance of uncertainty, core self-evaluation, attention control, and social interaction anxiety. The results revealed a significant and positive predictive relationship between intolerance of uncertainty and social anxiety (effect = 0.10; SE = 0.02; 95% CI = [0.00, 0.05]; p < 0.001). Intolerance of uncertainty directly and indirectly impacted social anxiety via three pathways: the independent mediating influence of core self-evaluation (effect = 0.15; SE = 0.02; 95% CI = [0.12, 0.18]; p < 0.001), the independent mediating influence of attentional control (effect = 0.03; SE = 0.01; 95% CI = [0.02, 0.05]; p < 0.001), and a serial mediation effect involving both core self-evaluation and attentional control (effect = 0.04; SE = 0.01; 95% CI = [0.03, 0.06]; p < 0.001). These direct and indirect effects contributed 30.03% and 69.97% to the overall effect, respectively. This study offers novel insights for interventions and treatments targeting social anxiety in university students.

Translation and validation of the Arabic version of Mindful Attention Awareness Scale (MAAS) among the Lebanese population

This study aimed to evaluate the psychometric properties of the Arabic version of the MAAS (A-MAAS) among Lebanese adults, determine its reliability and validity, and explore its associated factors. A cross-sectional study was conducted from August to December 2023. A sample of 483 Lebanese adults, aged between 18 and 60 years, from all the Lebanese governorates completed a questionnaire consisting of three sections: socio-demographic characteristics, health-related questions, and the Arabic versions of the Mindful Attention Awareness Scale (A-MAAS) and the Positive and Negative Affect Schedule (PANAS). Our findings revealed that the A-MAAS exhibited strong internal consistency (Cronbach's alpha = 0.932). Confirmatory factor analysis (CFA) confirmed the one-dimensional structure accuracy of the scale, and the significant correlations with PANAS scales supported its convergent validity. Test-retest results displayed strong reliability (ICC = 0.983). The study revealed significant associations, indicating that worse memory performance, smoking, and negative emotions were linked to lower A-MAAS scores, suggesting lower levels of mindfulness. Our study contributes to the growing body of evidence supporting the utility of the MAAS in assessing mindfulness and attention. Continued research efforts will be crucial for advancing our understanding and application of mindfulness assessment tools in diverse populations and clinical settings.

"Regulating my anxiety worsens the safety of my driving": The synergistic influence of spatial anxiety and Self-regulation on driving behavior

Spatial Anxiety (SA) can be defined as the fear and apprehension experienced during tasks that require spatial thinking and may negatively impact the execution of daily actions. Although it has been explored in several research fields, limited research has explored the effects of SA on specific driving behaviours. In the current study, it was hypothesised that the severity of SA affects risky driving behaviours, and that this relationship is mediated by the driver's self-regulation abilities. Self-reported SA symptoms, driving self-regulation abilities, and risky driving behaviours (i.e., errors, violations, and lapses) were examined in 838 Italian drivers. Data were analysed through linear regressions and path analysis models, controlling for sociodemographic variables. The results showed the negative effects of SA on driving errors and lapses. As hypothesised, a driver's self-regulation abilities mediated the influence of SA on driving lapses, but not on errors nor violations. These findings suggest that the inclination to self-regulate the SA experienced while driving contribute to increase the occurrence of driving lapses. Showing specific pathways through which SA impacts risky driving, these results provide valuable insights for the development of 'driver-focused' road safety interventions.

Inhibition moderates the effect of attentional bias modification for reducing residual depressive symptoms: A randomized sham-controlled clinical trial

OBJECTIVES

Residual symptoms represent risk factor for relapse. Attention bias modification (ABM) may reduce clinical and sub-clinical depressive symptoms, indicating that is may be of relevance when preventing relapse. Current evidence suggests that executive functions may moderate the outcome of interventions targeting depressive symptoms.

METHODS

We assessed inhibition and shifting as indicators of executive functioning by means of the Color-Word Interference Test (i.e., "Stroop task"). These baseline characteristics were investigated as moderator of the effect of ABM on depression symptoms in a double-blinded randomized sham-controlled trial of ABM including patients with a history of recurrent depression (N = 301). Inclusion and follow-ups took place from January 2015 to October 2016. The trial was retrospectively registered #NCT02658682 January 2016.

RESULTS

The moderation analysis was based on the interaction term ABM x Stroop. Scaled inhibition scores ≤10.8, but not shifting ability, moderated the effect of ABM compared to sham on clinician-rated depression (HDRS). The difference from the 15th to the 85th percentile of the inhibition score was about 1 HDRS-point, indicating a small effect size. No moderation was found when self-reported depression and AB were the outcome. Post-hoc power calculation indicates risk of Type-II error.

CONCLUSION

When targeting depressive symptoms, ABM seems to be somewhat more effective in patients with weak inhibitory control. This suggests that evaluating the level of inhibition in individual patients could provide some information when making decisions about prescribing ABM to reduce residual symptoms, but the clinical implications of this is uncertain due to an overall small effect size attributable to ABM. Future studies should examine whether inhibitory control still is a relevant moderator when comparing ABM to treatment options other than the sham control condition.

Adolescents' trait mindfulness and psychological stress: The mediating role of attention

INTRODUCTION

Based on the Combined Cognitive Biases Hypothesis, the current study via two parallel studies aims to explore the potential mediating role of attention biases and attention control regarding the link between trait mindfulness and psychological stress in adolescents.

METHODS

For Study 1, we collected self-reported data from 2123 Chinese adolescents (mean age = 15.6 years, SD = 2.37; 52.8% female) in four schools. The participants completed measures of trait mindfulness, perceived stress, and attention bias. Mediation analysis was employed to investigate the potential mediating effect of attention bias. In Study 2, 123 participants (mean age = 17.7 years, SD = 2.68; 41.46% female) completed the attention network task after inducing attention bias. Then, trait mindfulness and perceived stress were measured. Mediation analysis was employed to investigate the potential mediating effect of attention control (alerting, orienting, and conflict monitoring) under attention bias.

RESULTS

Study 1 demonstrated a significant mediating effect of negative attention bias ([-0.13, -0.07], p < .05) but not positive attention bias in the relationship between trait mindfulness and psychological stress. Study 2 revealed that conflict monitoring in negative attention bias ([-0.41, -0.16], p < .05), rather than alerting and orienting in negative attention bias, showed a significant mediating effect on the association between trait mindfulness and psychological stress.

CONCLUSIONS

Findings from the two studies suggest that conflict monitoring during negative attention bias may be the underlying mechanism through which trait mindfulness helps mitigate psychological stress in adolescents.

The brief mind wandering three-factor scale (BMW-3)

In recent years, researchers from different fields have become increasingly interested in measuring individual differences in mind wandering as a psychological trait. Although there are several questionnaires that allow for an assessment of people's perceptions of their mind wandering experiences, they either define mind wandering in a very broad sense or do not sufficiently separate different aspects of mind wandering. Here, we introduce the Brief Mind Wandering Three-Factor Scale (BMW-3), a 12-item questionnaire available in German and English. The BMW-3 conceptualizes mind wandering as task-unrelated thought and measures three dimensions of mind wandering: unintentional mind wandering, intentional mind wandering, and meta-awareness of mind wandering. Based on results from 1038 participants (823 German speakers, 215 English speakers), we found support for the proposed three-factorial structure of mind wandering and for scalar measurement invariance of the German and English versions. All subscales showed good internal consistencies and moderate to high test-retest correlations and thus provide an effective assessment of individual differences in mind wandering. Moreover, the BMW-3 showed good convergent validity when compared to existing retrospective measures of mind wandering and mindfulness and was related to conscientiousness, emotional stability, and openness as well as self-reported attentional control. Lastly, it predicted the propensity for mind wandering inside and outside the lab (as assessed by in-the-moment experience sampling), the frequency of experiencing depressive symptoms, and the use of functional and dysfunctional emotion regulation strategies. All in all, the BMW-3 provides a brief, reliable, and valid assessment of mind wandering for basic and clinical research.

Macro-scale patterns in functional connectivity associated with ongoing thought patterns and dispositional traits

Complex macro-scale patterns of brain activity that emerge during periods of wakeful rest provide insight into the organisation of neural function, how these differentiate individuals based on their traits, and the neural basis of different types of self-generated thoughts. Although brain activity during wakeful rest is valuable for understanding important features of human cognition, its unconstrained nature makes it difficult to disentangle neural features related to personality traits from those related to the thoughts occurring at rest. Our study builds on recent perspectives from work on ongoing conscious thought that highlight the interactions between three brain networks - ventral and dorsal attention networks, as well as the default mode network. We combined measures of personality with state-of-the-art indices of ongoing thoughts at rest and brain imaging analysis and explored whether this 'tri-partite' view can provide a framework within which to understand the contribution of states and traits to observed patterns of neural activity at rest. To capture macro-scale relationships between different brain systems, we calculated cortical gradients to describe brain organisation in a low-dimensional space. Our analysis established that for more introverted individuals, regions of the ventral attention network were functionally more aligned to regions of the somatomotor system and the default mode network. At the same time, a pattern of detailed self-generated thought was associated with a decoupling of regions of dorsal attention from regions in the default mode network. Our study, therefore, establishes that interactions between attention systems and the default mode network are important influences on ongoing thought at rest and highlights the value of integrating contemporary perspectives on conscious experience when understanding patterns of brain activity at rest.

Integrating habit science and learning theory to promote maintenance of behavior change: does adding text messages to a habit-based sleep health intervention (HABITs) improve outcomes for eveningness chronotype young adults? Study protocol for a randomized controlled trial

BACKGROUND

Eveningness chronotype-the tendency for later sleep and wake times-arises from a confluence of psychosocial, behavioral, and biological factors. With the onset and progression of puberty, many young people develop an eveningness chronotype, which remains prevalent through the transition into adulthood. Eveningness has been associated with increased risk for poorer health. While eveningness is modifiable, maintaining the necessary behavior changes can be challenging. The science on habits demonstrates that habit formation is a key mechanism for maintaining behavior change over time. Learning theory offers schedules of reinforcement that also hold promise for enhancing the maintenance of behavior change. The present study will evaluate the Habit-based Sleep Health Intervention (HABITs)-which combines the Transdiagnostic Intervention for Sleep and Circadian Dysfunction (TranS-C) with the science of habits-and a text message intervention informed by learning theory to attempt to sustainably modify the contributors to eveningness among young adults (18-30 years of age).

METHODS

Participants (N = 160) will be randomly allocated to HABITs and HABITs + Texts. Both interventions include HABITs which involves three 50-min sessions followed by six 30-min sessions. Alongside the latter six sessions, HABITs + Texts will concurrently receive the text message intervention. Aims 1-3 will compare HABITs + Texts to HABITs on improvements in the outcomes of (1) utilization of sleep health behaviors and habit formation, (2) sleep and circadian functioning, and (3) functioning in five health-relevant domains, in the short (post-treatment) and longer (6-month and 12-month follow-up) term. Exploratory analysis will (1) compare HABITs and HABITs + Texts on (a) if sleep health behavior habit formation mediates the effects of intervention on improvement in outcomes and (b) if intervention effects are moderated by select variables, and (2) to evaluate if HABITs (regardless of the text message intervention) is associated with an improvement in outcomes in the short and longer term.

DISCUSSION

This study has the potential to advance knowledge on (1) the value of leveraging the science of habits and learning theory in behavior change interventions, (2) the use of a low-cost and efficient intervention for habit formation and maintenance, (3) interventions that address eveningness chronotype, and (4) processes related to behavior change during emerging adulthood.

Probability, cost, and interpretation biases' relationships with depressive and anxious symptom severity: differential mediation by worry and repetitive negative thinking

People high in depressive or anxious symptom severity show repetitive negative thinking, including worry and rumination. They also show various cognitive phenomena, including probability, cost, and interpretation biases. Since there is conceptual overlap between these cognitive biases and repetitive negative thinking - all involve thinking about potential threats and misfortunes - we wondered whether repetitive negative thinking could account for (mediate) these cognitive biases' associations with depressive and anxious symptom severity. In three studies, conducted in two languages and cultures, cost bias and (in two studies) interpretation bias only predicted symptom severity via worry and repetitive negative thinking; this suggests these biases are actually associated with repetitive negative thinking, rather than with symptoms. In contrast, probability bias showed direct relationships with depressive (all studies) and anxious (two studies) symptom severity, suggesting its relationships with symptoms are partly independent of repetitive negative thinking. These results show the value of studying relationships among the various cognitive features of psychopathology. Furthermore, new interventions which target cognitive biases in depression or anxiety must show that they can improve upon cognitive behavioural therapy, which is already widely available, targets both repetitive negative thinking and probability bias, and is highly effective.

Eye-tracking analysis of attentional disengagement in phobic and non-phobic individuals

This study investigated threat-related attention biases using a new visual search paradigm with eye tracking, which allows for measuring attentional disengagement in isolation. This is crucial as previous studies have been unable to distinguish between engagement, disengagement, and behavioral freezing. Thirty-three participants (Mage = 28.75 years, SD = 8.98; 21 women) with self-reported specific phobia (spiders, snakes, and pointed objects) and their matched controls (Mage = 28.38 years, SD = 8.66; 21 women) took part in the experiment. The participants were instructed to initially focus on a picture in the center of the screen, then search for a target picture in an outer circle consisting of six images, and respond via a button press whether the object in the target picture was oriented to the left or right. We found that phobic individuals show delayed disengagement and slower decision times compared with non-phobic individuals, regardless of whether the stimulus was threat-related or neutral. These results indicate that phobic individuals tend to exhibit poorer attentional control mechanisms and problems inhibiting irrelevant information. We also confirmed a threat-unrelated shared feature effect with complex stimuli (delayed disengagement when an attended stimulus and an unattended target share common stimulus features). This process might play a role in various experimental setups investigating attentional disengagement that has not yet been considered. These findings are important, as good attentional control may serve as a protective mechanism against anxiety disorders.

Treatment as a moderator and executive function as a mediator of the effect of a mindfulness ecological momentary intervention for generalized anxiety disorder

BACKGROUND

Theory and research indicated that executive functioning (EF) correlated with, preceded, and stemmed from worry in generalized anxiety disorder (GAD). The present secondary analysis (Zainal & Newman, 2023b) thus determined whether EF domains mediated the effect of a 14-day (5 prompts/day) mindfulness ecological momentary intervention (MEMI) against a self-monitoring control (SM) for GAD.

METHOD

Participants (N = 110) diagnosed with GAD completed self-reported (Attentional Control Scale, GAD Questionnaire, Perseverative Cognitions Questionnaire) and performance-based tests (Letter-Number Sequencing, Stroop, Trail Making Test-B, Verbal Fluency) at baseline, post-treatment, and one-month follow-up (1MFU). Causal mediation analyses determined if pre-post changes in EF domains preceded and mediated the effect of MEMI against SM on pre-1MFU changes in GAD severity and trait repetitive negative thinking (RNT).

RESULTS

MEMI was more efficacious than SM in improving pre-post inhibition (β = -2.075, 95% [-3.388, -0.762], p = .002), working memory (β = 0.512, 95% [0.012, 1.011], p = .045), and set-shifting (β = -2.916, 95% [-5.142, -0.691], p = .010) but not verbal fluency and attentional control. Within groups, MEMI but not SM produced improvements in all examined pre-post EF outcomes except attentional control. Only pre-post improvements in inhibition mediated the effect of MEMI against SM on pre-1MFU reductions in GAD severity (β = -0.605, 95% [-1.357, -0.044], p = .030; proportion mediated = 7.1%) and trait RNT (β = -0.024, 95% [-0.054, -0.001], p = .040; proportion mediated = 7.4%). These patterns remained after conducting sensitivity analyses with non-linear mediator-outcome relations.

CONCLUSIONS

Optimizing MEMI for GAD might entail specifically boosting inhibition plausibly by augmenting it with dialectical behavioral therapy, encouraging high-intensity physical exercises, and targeting negative emotional contrast avoidance.

Attention control mediates the relationship between mental imagery vividness and emotion regulation

Contradictory findings suggest mental imagery may both exacerbate and protect against negative affect. We aimed to reconcile these contradictory findings by considering individual differences (N=989) in imagery vividness, attention control, resilience, emotion regulation strategy, and negative affect (depressive, anxious, and posttraumatic stress symptomology). We hypothesized that attention control would mediate relationships between imagery vividness and emotion regulation strategy use, and psychopathology symptomology. Results revealed that imagery vividness, as mediated by attention control, predicted greater levels of healthy reappraisal and deleterious rumination. Attention control also mediated negative relationships between imagery vividness and catastrophizing, self-blame, and psychopathology symptomology. An exploratory latent structural equation model revealed that imagery vividness and attention control aggregated positively with reappraisal and resilience scores. The present investigation suggests an adaptive function of imagery vividness via the indirect effects of attention control, facilitating adaptive emotion regulation and limiting maladaptive strategy use, thereby protecting against negative affect.

The Interrelationships Between Cognitive Biases for Pain: An Experimental Study

Contemporary pain models highlight cognitive-processing biases (ie, attention bias [AB], interpretation bias [IB], and memory bias [MB]) as key processes that contribute to poor pain outcomes. However, existing research has yielded inconsistent findings regarding the presence and impact of these biases on pain outcomes. Recognizing the need to explore these biases simultaneously, contemporary pain models suggest that cognitive biases (CBs) are interrelated, and may have a combined impact upon pain problems. The current study aims to investigate the interrelationships between CBs using the PainAIM paradigm, a novel approach enabling simultaneous evaluation of pain-related AB, IB, and MB using cues signaling actual pain rather than symbolic information. We hypothesized the presence and positive associations of biases for pain-related cues and the predictive value of combined AB and IB for poor pain outcomes. Eighty-four healthy participants completed the PainAIM paradigm, followed by a cold pressor task probing pain experience and pain-related task interference. The results indicated an inverse relationship between AB and IB for ambiguous pain cues. In addition, there was a positive association between participants' AB for ambiguous pain and their MB for the same cues. Contrary to our hypotheses, CB indices did not predict experimental pain outcomes. These findings provide support for the interrelationships between pain-related CBs. However, future research on the temporal order of CBs and their combined impact on pain outcomes is needed. By overcoming the limitations associated with traditional paradigms, the PainAIM paradigm offers a promising research tool for the further study of combined CBs in the context of pain. PERSPECTIVE: The current study provides insight into the associations between pain-related CBs (AB, IB, and MB) using ecologically valid (ambiguous) pain cues. The results indicated an inverse association between pain-related AB and IB, while a positive association was found between AB and MB. CBs did however not predict experimental pain outcomes.

Group metacognitive therapy for children and adolescents with anxiety and depression: A preliminary trial and test of proposed mechanisms

Preliminary research supports the feasibility of metacognitive therapy (MCT) in children with generalized anxiety, but the effectiveness of MCT in treating children with other anxiety and depressive disorders largely remains unknown. The purpose of this study was to investigate the effects associated with MCT in targeting symptoms of anxiety and depression in children and adolescents and to investigate mechanisms proposed by the metacognitive model. Ninety-seven participants aged 10-17 years (M = 12.9 ± 1.9, 82.5 % females) with anxiety and depressive disorders received eight sessions of group MCT. Participants were diagnostically assessed at pre- and post-treatment and completed symptom and process measures before, during, and after treatment, and again at three- and six-month follow-up. Multilevel models were conducted to investigate treatment-related and mediation effects. Results showed large reductions in total symptoms following treatment (d = 1.28). These reductions were associated with, and temporally preceded by changes in cognitive attentional syndrome (CAS), metacognitive beliefs, and self-reported attention control, but not objective attention control. Treatment gains were maintained at six-month follow-up (d = 1.18). Our results indicate that MCT may be a promising treatment for children and adolescents with anxiety and depression and provide preliminary evidence of changes in CAS, metacognition, and perceived attention control as potential drivers of treatment effects.

Mindfulness and Procrastination Among University EFL Learners: The Role of Attention Control and Self-Regulated Learning

The present study aimed to investigate the interconnections among mindfulness, self-regulated learning (SRL), attention control, and procrastination among English as a foreign language (EFL) learner in Iran. Additionally, the mediating influence of SRL and attention control on mindfulness-procrastination link were tested. For this purpose, 272 university EFL students were conveniently selected and administered self-report questionnaires. Structural equation modeling and mediation analyses were employed. The results indicated that greater levels of SRL and attention control were related to lower levels of procrastination. Further, mindfulness directly predicted SRL and attention control. The findings also showed that although mindfulness did not directly account for procrastination, it could indirectly impact procrastination via the mediation of SRL and attention control. The findings were discussed, and implications and suggestions for future research were presented.

Development and validation of a Disorganised Thoughts Scale: a new measure to assess thinking difficulties in the general population

BACKGROUND

Disordered thinking is a condition that can manifest in not only clinical cases (e.g., psychotic disorders), but also the wider general population. However, there is no current method to measure the specific cognitive processes experienced during such a condition. Therefore, this study aimed to develop a new self-report measure, the Disorganised Thoughts Scale (DTS), that can assess disorganised thinking in the general population.

METHODS

To achieve this aim, a survey was developed and shared online with four independent samples, including a sample of Australians in the general population (N = 321) and three samples (N = 200 each) that were controlled for their substance use (i.e., frequent alcohol and cannabis use; non-frequent substance use). Exploratory and confirmatory factor analyses, and reliability analyses, were used to test the internal validity, whilst correlational analyses were implemented to examine the external validity.

RESULTS

The exploratory factor analysis revealed a two-factor structure (10 items each) measuring Positive thought disorder (i.e., accelerated, uncontrollable, and incongruent thinking) and Negative thought disorder (i.e., inhibited, disjointed, and disorientated thinking). This internal structure was confirmed with subsequent confirmatory factor and reliability analyses (α = 0.90 to 0.97) in the three substance-controlled groups. Concurrent validity was also supported, as the DTS exhibited strong correlations with established measures of general cognitive difficulties, specific self-regulatory dysfunctions, and psychopathological symptomology. Finally, the measure was also shown to be significantly higher in cohorts who exhibited a higher degree of psychological distress and who frequently used substances (i.e., alcohol and cannabis).

CONCLUSIONS

Overall, this study provided preliminary evidence to suggest that the DTS is a sound measure of disorganised thought that is linked to psychopathology and substance use in non-clinical populations. The measure could be used in future research which seeks to better understand how thinking effects, and is affected by, various psychological conditions.

Linking a latent variable trait-state-occasion model of emotion regulation to cognitive control

Emotion dysregulation (ED) is a vulnerability factor for affective disorders that may originate from deficits in cognitive control (CC). Although measures of ED are often designed to assess trait-like tendencies, the extent to which such measures capture a time-varying (TV) or state-like construct versus a time-invariant (TI) or trait-like personality characteristic is unclear. The link between the TV and TI components of ED and CC is also unclear. In a 6-wave, 5-month longitudinal study, community participants (n = 1281) completed the Difficulties in Emotion Regulation Scale (DERS-16), a commonly used measure of ED and measures of CC. A latent variable (trait-state-occasion) model showed that the proportion of TI factor variance (.80) was greater than the TV factor variance (.19). Although TV factor stability was significant, the coefficients were small in magnitude. Furthermore, regression weights for the ED TI factor (average β  = -.62) were significant and larger than those for the TV factor (average β  = -.10) in predicting latent CC at each of the six-time points. These findings suggest that ED, as assessed by the DERS-16, is largely TI and this TI component is more strongly linked to CC than the TV component.

Attention in hindsight: Using stimulated recall to capture dynamic fluctuations in attentional engagement

Attentional engagement is known to vary on a moment-to-moment basis. However, few self-report methods can effectively capture dynamic fluctuations in attentional engagement over time. In the current paper, we evaluated the utility of stimulated recall, a method wherein individuals are asked to remember their subjective states while using a mnemonic cue, for the measurement of temporal changes in attentional engagement. Participants were asked to watch a video lecture, during which we assessed their in-the-moment levels of attentional engagement using intermittent thought probes. Then, we used stimulated recall by cueing participants with short video clips from the lecture to retrospectively assess the levels of attentional engagement they had experienced when they first watched those clips within the lecture. Experiment 1 assessed the statistical overlap between in-the-moment and video-stimulated ratings. Experiment 2 assessed the generalizability of video-stimulated recall across different types of lectures. Experiment 3 assessed the impact of presenting video-stimulated probe clips in non-chronological order. Experiment 4 assessed the effect of video-stimulated recall on its own. Across all experiments, we found statistically robust correspondence between in-the-moment and video-stimulated ratings of attentional engagement, illustrating a strong convergence between these two methods of assessment. Taken together, our findings indicate that stimulated recall provides a new and practical methodological approach that can accurately capture dynamic fluctuations in subjective attentional states over time.

The role of attentional control in moderating attentional bias towards game-related stimuli in individuals with a high tendency for internet gaming addiction

Background

The aim of this study was to elucidate individual difference factors that modulate the attentional processing of game stimuli to explain the heterogeneity of extant findings. The current study examined whether individual differences in components of attentional control (AC-shifting and AC-focusing) moderated the link between internet gaming addiction symptom and attentional engagement to and disengagement biases from game-relevant cues.

Methods

A total of 75 male undergraduate students who have played League of Legend (LOL) for more than 2 years completed well-established self-report questionnaires of internet gaming disorder symptoms and attentional control. The attentional bias toward game stimuli was measured for attentional engagement and disengagement using the attentional response to the distal vs. proximal emotional information (ARDPEI) task.

Results

The results revealed that attentional control was a significant moderator of the relationship between internet game addiction symptoms and attentional disengagement bias. Further analyses revealed a positive relationship between internet game addiction symptoms and attentional disengagement bias only among those with low levels of AC-shifting ability. Contrary to our expectations, AC-shifting also moderated the relationship between internet gaming disorder and attentional engagement bias. The positive relationship between internet game addiction symptoms and attentional engagement bias only appeared among those with low levels of AC-shifting ability. Individual differences in AC-focusing did not moderate the relationship between internet gaming disorder and any attentional bias.

Conclusion

This study confirmed that the greater the symptoms of game addiction, the stronger the attentional bias, especially in individuals with low AC-shifting ability. Therefore, it is necessary to examine sub-factors of AC in understanding the nature of attentional bias mechanisms in the development of internet game addiction and consider it as a psychological intervention to improve attentional bias.

Reduction of Aversive Learning Rates in Pavlovian Conditioning by Angiotensin II Antagonist Losartan: A Randomized Controlled Trial

BACKGROUND

Angiotensin receptor blockade has been linked to aspects of aversive learning and memory formation and to the prevention of posttraumatic stress disorder symptom development.

METHODS

We investigated the influence of the angiotensin receptor blocker losartan on aversive Pavlovian conditioning using a probabilistic learning paradigm. In a double-blind, randomized, placebo-controlled design, we tested 45 (18 female) healthy volunteers during a baseline session, after application of losartan or placebo (drug session), and during a follow-up session. During each session, participants engaged in a task in which they had to predict the probability of an electrical stimulation on every trial while the true shock contingencies switched repeatedly between phases of high and low shock threat. Computational reinforcement learning models were used to investigate learning dynamics.

RESULTS

Acute administration of losartan significantly reduced participants' adjustment during both low-to-high and high-to-low threat changes. This was driven by reduced aversive learning rates in the losartan group during the drug session compared with baseline. The 50-mg drug dose did not induce reduction of blood pressure or change in reaction times, ruling out a general reduction in attention and engagement. Decreased adjustment of aversive expectations was maintained at a follow-up session 24 hours later.

CONCLUSIONS

This study shows that losartan acutely reduces Pavlovian learning in aversive environments, thereby highlighting a potential role of the renin-angiotensin system in anxiety development.

Mediating role of right superior corona microstructural changes in linking attentional control and trait anxiety among youth with childhood maltreatment

This study explores the neural correlates between attentional control and trait anxiety among youth with a history of childhood maltreatment. Using diffusion tensor imaging, we investigated the microstructural integrity of brain white matter, particularly focusing on the right superior corona radiata (SCA-R). A total of 173 university students with experiences of childhood maltreatment underwent behavioral assessments using the Attentional Control Scale and trait anxiety measurements via the Spielberger State-Trait Anxiety Inventory. Our analysis found significant correlations between fractional anisotropy values in the SCA-R and trait anxiety levels, controlled for age and sex. Notably, SCA-R fractional anisotropy values partially mediated the relationship between attentional control and trait anxiety, suggesting a potential pathway through which attentional control could mitigate trait anxiety. These insights highlight attentional control as a potential mitigating factor against trait anxiety, particularly noting the partial mediation role of the SCA-R. Importantly, this study is descriptive and correlative, highlighting associations rather than causal relationships among the variables studied. These findings enhance our understanding of the neural mechanisms underlying anxiety in individuals with a history of childhood maltreatment.

Negative attention bias and attentional control as mechanisms in the association between insomnia and depression in young people

Evidence supports a causal role of insomnia in the development and maintenance of depression, yet mechanisms underlying this association in young people are not well established. Attention biases have been implicated separately in the sleep and depression fields and represents an important candidate mechanism. Poor sleep may lead to a negative attention bias (characteristic of depression) by impacting attentional control. This study assessed the hypothesis that attentional control and negative attention bias would sequentially mediate the relationship between insomnia and depressive symptoms in an unselected sample of young people (17-24 years). Concerns have been raised regarding the psychometric properties of tasks used to measure attention bias, and a Dual-Probe Task is emerging as a more reliable measure. Participants (N = 275, Male = 59, Mage = 19.40) completed the Dual-Probe Task, a behavioural measure of attentional control, and self-report measures of insomnia and depression. Participants completed a one-week sleep diary. Results were consistent with negative attention bias, but not attentional control, as a mechanism which partially accounts for the relationship between sleep (i.e., insomnia severity, sleep duration, sleep efficiency, sleep latency) and depression. This study highlights sleep and negative attention bias as potentially modifiable risk factors to reduce depressive symptoms in young people.

How we teach mindfulness matters: Adolescent development and the importance of informal mindfulness

Given high levels of adolescent stress and educational institutions' key role in supporting students' mental health, mindfulness instruction is increasingly being implemented in schools. However, there is growing evidence adolescents find traditionally taught formal mindfulness (e.g., structured regular practice like meditation) challenging. Indeed, school-based studies report high levels of student non-compliance and lack of engagement with formal mindfulness strategies. Thus, informal mindfulness practices (e.g., unstructured brief moments integrated within daily routine) may be more accessible and developmentally appropriate for adolescents. Using a randomized experimental school-based design, this study sought to parse out the acceptability and effectiveness of formal and informal mindfulness for adolescents over time. Adolescents (n = 142; 73.9% female) were randomly assigned to a 4-week formal mindfulness, informal mindfulness, or comparison group and assessed on mental health, well-being, and educational outcomes. The informal mindfulness group (a) was more likely to report intending to frequently use the strategies (p = .025, Cramer's V = .262) and (b) reported increased dispositional mindfulness (i.e., general tendency to be mindful) from baseline to follow-up (p = .049, ηp2 = .034) which in turn mediated benefits on depression (indirect effect = -.15, 95% CI [-.31, -.03]), anxiety (indirect effect = -.21, 95% CI [-.36, -.06]), general stress (indirect effect = -.16, 95% CI [-.32, -.04]), school-related stress (indirect effect = -.15, 95% CI [-.28, -.05]), negative affect (indirect effect = -.17, 95% CI [-.35, -.04]), and attentional control (indirect effect = .07, 95% CI [.01, .13]). Thus, brief informal mindfulness strategies may be easier for students to use on a regular basis than formal mindfulness. Overall, these findings highlight the importance of going beyond a one-size-fits-all approach by offering accessible and engaging school-based mindfulness instruction to students. Recommendations for school psychologists seeking to teach mindfulness to adolescents are discussed, including the need to directly teach how to integrate informal mindfulness strategies in students' lives.

Prevention of internalizing difficulties in the middle years: Protocol for a noninferiority randomized trial of Mindfulness-Based Cognitive Therapy for Children and Cognitive Behavioural Therapy

AIM

Mindfulness-based interventions have been tested as preventive programs for childhood internalizing difficulties, but most research has been at a 'universal' level with small to null effects. Mindfulness-Based Cognitive Therapy for Children (MBCT-C) has similar effects to Cognitive Behaviour Therapy (CBT) when used as a small-group, targeted preventive program. Knowledge gaps include the longer-term effectiveness of MBCT-C relative to CBT and the benefits of adding a parent module. This trial aims to compare MCBT-C to traditional CBT, including a parent module, to 15-months post-intervention and to test the feasibility and acceptability of adding a parent module.

METHODS

Participants will be recruited from primary schools in areas of socio-economic disadvantage in South Australia (n = 194). Children (aged 9-12) years with signs of internalizing difficulties (e.g., shy, withdrawn, worried), and their parents, will be eligible for this two-armed randomized controlled non-inferiority trial (RCT). Children will participate in 10 group sessions of MBCT-C or CBT, facilitated by psychologists, and parents from both conditions will participate in two parent-only group sessions. Child self-report measures include depression and anxiety, as well as attention, mindfulness and self-compassion. Parent measures include symptoms of depression and anxiety, mindfulness, and parent-child relationship strength. The primary outcome will be child anxiety and depression (Revised Child Anxiety and Depression Scale-25). Measures will be collected pre and post intervention, and at 3, 6, 12 and 15-month follow up.

RESULTS

Schools will be recruited from October 2022. Nomination of children will commence from February 2023. Program implementation will begin May 2023.

CONCLUSIONS

This trial will have implications for the feasibility of involving parents in preventative programs, as well as whether mindfulness-based interventions prevent internalizing difficulties over time.

Comparing Self-Report vs. Performance Measures of Attentional Control and Efficiency

Background: The Attention Control Scale (ATTC) is a widely used self-report measure of attentional control capacities. However, research questions whether it accurately substitutes for objective attention control tasks. This study investigated ATTC's correlation with the Attention Network Test (ANT) across alerting, orienting, and executive control networks. We also used the Inverse Efficiency Score (IES) as an additional factor to check ATTC using ANT. Methods: We administered 143 participants who completed the ATTC questionnaire and ANT behavioral test assessing network efficiencies. Results: The results showed non-significant ATTC-ANT correlations across all networks. In an additional analysis, while the ATTC demonstrated factorial validity, subjective control was disconnected from actual attention regulation efficiency. A small male advantage emerged for executive control. Conclusions: Dissociations likely stem from attention complexity and method variances rather than overlap. The findings do not support the ATTC as a stand-alone proxy for performance-based measurement. Multifaceted assessments are essential for comprehensively capturing attentional control.

Mindfulness enhances cognitive functioning: a meta-analysis of 111 randomized controlled trials

BACKGROUND

Currently no comprehensive meta-analysis of MBI efficacy on global and unique cognitive subdomains exist.

METHOD

Examined the effects of MBIs on global cognition and 15 cognitive subdomains. Inclusion criteria: meditation naïve participants; randomized controlled trial; outcome included one objective or subjective cognitive functioning measure; primary focus was teaching mindfulness skills. Exclusion criteria: inadequate data; one-session ; control condition contained any MBI component. Robust variance estimation and moderator analyses controlling for presence of treatment fidelity were conducted.

RESULTS

One-hundred-and-eleven RCTs (n = 9,538) met eligibility criteria. MBIs had small-to-moderate significant effects on global cognition, executive attention, working memory accuracy, inhibition accuracy, shifting accuracy, sustained attention, and subjective cognitive functioning (vs. waitlist/no-treatment, g = 0.257-0.643; vs. active controls, g = 0.192-0.394). MBIs did not impact executive functioning (EF) latency indices, verbal fluency, processing speed, episodic memory, and cognitive error. Treatment effects were stronger for those with elevated psychiatric symptoms vs. healthy controls, and medical samples, studies with complete-case (vs. intention-to-treat) analysis, face-to-face (vs. self-guided) delivery, and non-standard (vs. standard MBI).

CONCLUSION

MBIs consistently yielded small-to-moderate yet practically meaningful effect sizes on global cognition and six cognitive subdomains that captured accuracy vs. latency-based indices of EF and sustained accuracy.

Examining attentional control deficits in adolescents with test anxiety: An evidential synthesis using self-report, behavioral, and resting-state EEG measures

Attentional control theory suggests that test anxiety hinders individuals' attentional control, aiding our understanding of how test anxiety may impair cognitive function. However, various methods used to assess attentional control have yielded inconsistent findings. Moreover, past studies, especially on adolescents, that examine the distinct impacts of worry and the emotional components of test anxiety on individuals' attentional control capacity are scarce. This study, using self-report, behavioral, and resting-state EEG measures, explores how worry and emotionality, impact attentional control in adolescents. It enhances our understanding of the link between test anxiety and cognitive function. Referring to the effect size from prior studies, a total of 42 adolescents took part in the study. We used the Test Anxiety Inventory, due to it can assess worry and emotionality components. We employed three widely-utilized measures of attentional control: the Attentional Control Scale (ACS), the Go/Nogo task, and resting-state electroencephalography measures (alpha oscillation and the theta/beta power ratio). Both worry and emotionality components were significantly and negatively correlated with the ACS scores. Unlike worry, emotionality demonstrated a significant positive correlation with response times for the Go trials and alpha power in the parietal cortex. These results suggest that, emotionality, but not worry, is highly correlated with attentional control deficits in adolescents. This study underscores the significance of distinguishing between the components of test anxiety, which aids in comprehending the negative impacts of test anxiety on adolescents' academic performance.

Control strategy under pressure situations: performance pressure conditionally enhances proactive control

Previous research and theories have demonstrated that attentional control plays a crucial role in explaining the choking phenomenon (i.e., the performance decrements) under pressure situations. Attentional control is thought to function through two distinct control strategies: proactive control (i.e., a sustained and anticipatory strategy of control) and reactive control (i.e., a transient strategy of control). However, little is known about how performance pressure affects these control strategies. The present study was designed to address this issue. Participants were instructed to complete a continuous performance task (AX-CPT40) under pressure situations. The results showed that individuals under high-pressure situations tended to use proactive control rather than reactive control. Moreover, performance pressure resulted in a more liberal response bias following an A-cue, consistent with an increased use of proactive control. Importantly, the proactive behavioral index calculated on RTs showed that the increased proactive control mainly occurred in the short interval between the cue and probe, but not in the long interval. This suggests that individuals under high-pressure situations are unlikely to employ a proactive control strategy in a situation that requires more attentional resources. In summary, our results provide initial evidence that performance pressure conditionally enhances proactive control, which contributes to a deeper understanding of the dynamic adjustment of control strategies under pressure situations.

Effects of mindfulness-based cognitive therapy for Chinese adults with PTSD symptoms: protocol for a randomised controlled trial

INTRODUCTION

Emerging evidence supports mindfulness as a potential psychotherapy for post-traumatic stress disorder (PTSD). Individuals with subthreshold PTSD experience significant impairment in their daily life and functioning due to PTSD symptoms, despite not meeting the full diagnostic criteria for PTSD in DSM-5. Mindfulness skills, including non-judgmental acceptance, attentional control and openness to experiences may help alleviate PTSD symptoms by targeting characteristics such as intensified memory processing, dysregulated hyperarousal, avoidance, and thought suppression. This trial aims to test the effects of mindfulness-based cognitive therapy (MBCT) when compared to an active control.

METHOD AND ANALYSIS

This 1:1 randomised controlled trial will enroll 160 participants with PTSD symptoms in 2 arms (MBCT vs. Seeking Safety), with both interventions consisting of 8 weekly sessions lasting 2 h each week and led by certified instructors. Assessments will be conducted at baseline (T0), post-intervention (T1), and 3 months post-intervention (T2), with the primary outcome being PTSD symptoms measured by the PTSD checklist for DSM-5 (PCL-5) at T1. Secondary outcomes include depression, anxiety, attention, experimental avoidance, rumination, mindfulness, and coping skills. Both intention-to-treat and per-protocol analyses will be performed. Mediation analysis will investigate whether attention, experimental avoidance, and rumination mediate the effect of mindfulness on PTSD symptoms.

DISCUSSION

The proposed study will assess the effectiveness of MBCT in improving PTSD symptoms. The findings are anticipated to have implications for various areas of healthcare and contribute to the enhancement of existing intervention guidelines for PTSD.
