ABSTRACT

Open science refers to a set of practices that aim to make scientific research more transparent, accessible, and reproducible, including pre-registration of study protocols, sharing of data and materials, the use of transparent research methods, and open access publishing. In this commentary, we describe and evaluate the current state of open science practices in behavioral addiction research. We highlight the specific value of open science practices for the field; discuss recent field-specific meta-scientific reviews that show the adoption of such practices remains in its infancy; address the challenges to engaging with open science; and make recommendations for how researchers, journals, and scientific institutions can work to overcome these challenges and promote high-quality, transparently reported behavioral addiction research. By collaboratively promoting open science practices, the field can create a more sustainable and productive research environment that benefits both the scientific community and society as a whole.

ABSTRACT

The replication crisis has stimulated researchers around the world to adopt open science research practices intended to reduce publication bias and improve research quality. Open science practices include study pre-registration, open data, open access, and avoiding methods that can lead to publication bias and low replication rates. Although gambling studies uses similar research methods as behavioral research fields that have struggled with replication, we know little about the uptake of open science research practices in gambling-focused research. We conducted a scoping review of 500 recent (1/1/2016-12/1/2019) studies focused on gambling and problem gambling to examine the use of open science and transparent research practices. Our results showed that a small percentage of studies used most practices: whereas 54.6% (95% CI: [50.2, 58.9]) of studies used at least one of nine open science practices, each practice's prevalence was: 1.6% for pre-registration (95% CI: [0.8, 3.1]), 3.2% for open data (95% CI: [2.0, 5.1]), 0% for open notebook, 35.2% for open access (95% CI: [31.1, 39.5]), 7.8% for open materials (95% CI: [5.8, 10.5]), 1.4% for open code (95% CI: [0.7, 2.9]), and 15.0% for preprint posting (95% CI: [12.1, 18.4]). In all, 6.4% (95% CI: [4.6, 8.9]) of the studies included a power analysis and 2.4% (95% CI: [1.4, 4.2]) were replication studies. Exploratory analyses showed that studies that used any open science practice, and open access in particular, had higher citation counts. We suggest several practical ways to enhance the uptake of open science principles and practices both within gambling studies and in science more generally.

ABSTRACT

INTRODUCTION: Alcohol-related brain damage (ARBD) is an umbrella term referring to the neurocognitive impairments caused by excessive and prolonged alcohol use and the associated nutritional deficiencies. This study evaluated the outcomes of an online research-informed training program for ARBD which aimed to improve client outcomes by promoting support staff's awareness and confidence in working with clients who may have (or who are at risk of developing) the condition. METHODS: Staff working within a large non-governmental non-profit housing organisation (n = 883) enrolled in the training program. Questionnaires were used pre- and post-training to collect self-reported awareness of ARBD and confidence in supporting individuals with the condition. Semi-structured interviews were conducted with 27 staff members approximately 10 weeks post-completion of the program. Interviews were audio-recorded, transcribed verbatim and analysed by employing qualitative content analysis. RESULTS: Findings from the questionnaires indicated a significant increase in all measures after completing the training program. Three main themes were developed based on the interview data: changes to awareness and understanding; professional practice; and training-specific characteristics. Participants reported changes in their ability to identify potential service users with ARBD and confidence in doing so. DISCUSSION AND CONCLUSION: Our findings demonstrate that online training programs can be effective in improving support staff's ability to identify ARBD, potentially leading an increase in signposting service users to relevant services. The research-informed nature of the training demonstrates that translating research findings directly to frontline workers can have a substantial impact and may improve outcomes for this client group.

ABSTRACT

The "frontal lobe paradox" highlights a phenomenon in which a subset of patients who possess frontal lobe damage and exhibit marked impairments in everyday life are still able to able to verbally describe a logical course of action relating to a task and perform well in interview and test settings. Such cases pose a challenge with regard to the assessment of mental capacity within clinical settings. Recent position articles state that the frontal lobe paradox is a well-known phenomenon within the field of neuropsychology, anecdotal reports from clinicians in the UK suggest this is not the case. Consequently, we conducted a scoping review to examine the breadth and depth of literature relating to the frontal lobe paradox. Searches were conducted using electronic databases and search engines, which were supplemented with a snowball search of the references used within relevant literature. We identified and reviewed 28 documents specifically related to the frontal lobe paradox. Nearly 50% of all identified academic texts published since 2000 were position articles that cited a handful of case studies published between 1936 and 1986 as evidence for the phenomenon. We also observed instances of articles citing position articles as evidence of the frontal lobe paradox. Overall, our findings indicate a lack of readily accessible research specific to the frontal lobe paradox. In particular, there is a lack of contemporary research specific to the subject and an absence of clarification as to which syndromes and disorders are included within the term.

ABSTRACT

Objectives: The ability to accurately recall past gambling behavior and outcomes is essential for making informed decisions about future gambling. We aimed to determine whether online gambling customers can accurately recall their recent gambling outcomes and betting frequency. Method: An online survey was distributed to 40,000 customers of an Australian sports and race wagering website which asked participants to recall their past 30-day net outcome (i.e., total amount won or lost) and number of bets. We compared responses to these questions with participants' actual outcomes as provided by the online site. Results: Among the 514 participants who reported their net outcome, only 21 (4.09%) were accurate within a 10% margin of their actual outcome. Participants were most likely to underestimate their losses (N = 333, 64.79%). Lower actual net losses were associated with greater underestimation and overestimation of losses. Of the 652 participants who reported their gambling frequency, 48 (7.36%) were accurate within a 10% margin of their actual frequency. Most participants underestimated their number of bets (N = 454, 69.63%). Higher actual betting frequencies were associated with underestimating betting and lower actual frequencies with overestimating betting. Conclusions: The poor recall accuracy we observed suggests public health approaches to gambling harm minimization that assume people make informed decisions about their future bets based on past outcomes and available funds should be reconsidered. Findings also question the reliability of research outcomes predicated on self-reported gambling behavior. Research is needed to determine the best methods of increasing people's awareness of their actual expenditure and outcomes. (PsycInfo Database Record (c) 2022 APA, all rights reserved).

ABSTRACT

OBJECTIVE: Consumer Protection Tools (CPTs; e.g., deposit limits, timeouts) are provided by gambling sites to assist customers to gamble without harms. We aimed to understand how CPTs are used, and by which customers, which is essential to determine their effectiveness. METHOD: We examined the account data of 39,853 customers (median age = 33 years; 84% male) across six Australian wagering sites over 1 year (2018/07/01-2019/06/30). RESULTS: Most (83%) customers did not use any CPTs, with low rates of use for deposit limits (15.8%), timeouts (0.55%-1.57%), and self-exclusion tools (0.16%-0.57%) observed. Requiring customers to set a deposit limit or opt-out of setting one led to substantial increases in limit setting. Many customers who used limits later changed them, typically by increasing or removing them. Non-CPT users and deposit limit users were similar in their demographic and gambling characteristics, while comparatively, timeout and/or self-exclusion users were younger and displayed more risky gambling behaviors (e.g., higher net loss and betting frequency). CONCLUSIONS: Our findings suggest that voluntary deposit limits have inherent limitations in addressing harmful behaviors if consumers can easily increase or remove limits. The study suggests that greater efforts are needed to encourage CPT use among a broad customer base, including default limits requiring opt-out, greater restrictions on increasing or remove limits, and more persuasive communication of the benefits of timeouts.

ABSTRACT

AIMS: We tested the effectiveness of three different messages designed to increase limit-setting on gambling sites and sent these via e-mail or in-account notification to compare delivery modes. As a secondary aim, we examined the effects of limit-setting on gambling behaviour. DESIGN: A pre-registered, naturalistic randomized control trial using a 3 × 2 plus control design. SETTING: Four on-line Australian sports and racing wagering websites. PARTICIPANTS: A total of 31 989 wagering customers (reduced to 26,560 after eligibility screening) who had placed bets on at least 5 days in the past 30 [mean age = 41.4, standard deviation (SD) = 14.3; 79% male]. INTERVENTIONS AND COMPARATORS: Messages were sent via e-mail or in-account notification by on-line gambling operators and were designed to either: (1) be informative, describing the availability and purpose of the tool (informative messages), (2) highlight the benefits other people receive from using the tool (social messages) or (3) promote the benefit individuals could receive from using the tool (personal messages). A control group who did not receive messages was monitored for comparison. MEASUREMENTS: Our primary outcome was the number of customers who set a deposit limit within 5 days of receiving messages and secondary outcomes included pre- and post-message betting behaviour (e.g. average daily wager). FINDINGS: One hundred and sixty-one (0.71%) customers sent messages set limits compared to three (0.08%) controls [adjusted odds ratio (aOR) = 8.17, 95% confidence interval (CI) = 2.99, 33.76)]. Social and personal messages were no more effective than informative messages (aOR = 0.98, 95% CI = 0.65, 1.48; aOR = 0.93, 95% CI = 0.60, 1.44) and in-account messages were no more effective than e-mails (aOR = 1.02, 95% CI = 0.71, 1.49). Customers who set limits significantly decreased their average daily wager, the SD of daily wager, net loss and betting intensity compared with non-limit-setters. CONCLUSIONS: Messages to on-line gambling website customers are inexpensive, and may lead to small but impactful increases in setting deposit limits. Limit-setting may be an effective strategy for reducing gambling expenditure and intensity.

ABSTRACT

AIMS: Primary aim: to determine the efficacy of FAST (the Fast Alcohol Screening Test) for detecting harmful and dependent levels of alcohol use. Secondary aim: to compare the performance of the FAST to two short forms of the Alcohol Use Disorder Identification Test (AUDIT): the AUDIT-C and AUDIT-3. METHODS: Data from 3336 individuals in South Wales, compiled from full AUDIT datasets, were examined. AUROC analysis, alongside measures of sensitivity and specificity of the FAST, AUDIT-C and AUDIT-3 were utilized for the identification of harmful and dependent alcohol use. RESULTS: The FAST demonstrated efficacy in the identification of harmful and dependent levels of alcohol use, with superior performance to both the AUDIT-C and AUDIT-3. CONCLUSION: The present paper demonstrates the potential of the FAST as a cost- and time-effective method for appropriate screening and signposting in the stepped care model utilized by many health care and treatment services. Further studies are needed to ensure validity, both within the general population and for specific services and populations.

ABSTRACT

Little is understood about the attentional mechanisms that lead to perceptions of collective efficacy. This paper presents two studies that address this lack of understanding. Study one examined participant's (N = 59) attentional processes relating to positive, neutral, or negative emotional facial photographs, when instructed to select their "most confident" or "least confident" team. Eye gaze metrics of first fixation duration (FFD), fixation duration (FD), and fixation count (FC) were measured alongside individual perceptions of collective efficacy and emotional valence of the teams selected. Participants had shorter FFD, longer FD, and more FC on positive faces when instructed to select their most confident team (p < 0.05). Collective efficacy and emotional valence were significantly greater when participants selected their most confident team (p < 0.05). Study two explored the influence of video content familiarity of team-based observation interventions on attentional processes and collective efficacy in interdependent team-sport athletes (N = 34). When participants were exposed to familiar (own team/sport) and unfamiliar (unknown team/sport) team-based performance video, eye tracking data revealed similar gaze behaviors for the two conditions in terms of areas of interest. However, collective efficacy increased most for the familiar condition. Study one results indicate that the emotional expressions of team members influence both where and for how long we look at potential team members, and that conspecifics' emotional expression impacts on our perceptions of collective efficacy. For Study two, given the apparent greater increase in collective efficacy for the familiar condition, the similar attentional processes evident for familiar and unfamiliar team footage suggests that differences in meaning of the observed content dictates collective efficacy perceptions. Across both studies, the findings indicate the importance of positive emotional vicarious experiences when using team-based observation interventions to improve collective efficacy in teams.

ABSTRACT

OBJECTIVE: Existing studies relating to the prevalence of alcohol-related neurocognitive disorders (ARNDs; e.g., Korsakoff's Syndrome, alcohol-related dementia) are now outdated and few have been undertaken in the United Kingdom. The aim of this study was to estimate the prevalence of ARNDs in South Wales, U.K., and determine the specific diagnostic terms and criteria used in clinical practice. METHOD: A naturalistic, survey-based prevalence study was undertaken wherein data were collected retrospectively for all individuals with ARNDs attending services during all of 2015 and 2016. A diverse sample of health and social care services (N = 60) in South Wales took part in the study. RESULTS: A total of 490 individuals with ARNDs were identified by participating services, equating to an age-specific rate of 34 individuals per 100,000 inhabitants. Variability was observed across age ranges and genders, with most identified in the 45-64 year age range and a male:female ratio of 2.6:1. Twenty-three individuals younger than age 35 were identified, demonstrating an increase in younger cases compared with previous studies. Various diagnostic terms were used, with "alcohol-related brain damage" being most common. Only 6.3% of cases were diagnosed according to specific criteria and 44.3% were reported as having a "probable" ARND, meaning no official diagnosis had been designated but initial assessments indicated that they likely had an ARND. CONCLUSIONS: Findings provide a novel understanding of ARND prevalence in a previously understudied area, although the prevalence estimate is conservative and should be interpreted cautiously for reasons discussed. Findings also highlight an inconsistency between diagnoses presented in nosological systems (e.g., International Classification of Diseases-10th Revision) and those used in practice and therefore a need to evaluate novel diagnostic conceptualizations of alcohol-related neurocognitive impairment.

ABSTRACT

BACKGROUND AND AIMS: Recent investigations have highlighted the value of neuropsychological testing for the assessment and screening of Alcohol-Related Brain Damage (ARBD). The aim of the present study was to evaluate the suitability of the Addenbrooke's Cognitive Examination (ACE-III) and the Repeatable Battery for the Assessment of Neuropsychological Status (RBANS) for this purpose. METHODS: Comparing 28 participants with ARBD (11 with Korsakoff's Syndrome and 17 with the umbrella "ARBD" diagnosis) and 30 alcohol-dependent participants without ARBD (ALs) we calculated Area Under the Curve (AUC) statistics, sensitivity and specificity values, base-rate adjusted predictive values, and likelihood ratios for both tests. RESULTS: High levels of screening accuracy were found for the total scores of both the ACE-III (AUC = 0.823, 95% CIs [0.714, 0.932], SE = 0.056; optimal cut-off ≤86: sensitivity = 82%, specificity = 73%) and RBANS (AUC = 0.846, 95% CIs [0.746, 0.947], SE = 0.052; optimal cut-off ≤83: sensitivity = 89%, specificity = 67%) at multiple cut-off points. Removing participants with a history of polysubstance from the samples (10 ALs and 1 ARBD) improved the diagnostic capabilities of the RBANS substantially (AUC = 0.915, 95% CIs [0.831, 0.999], SE = 0.043; optimal cut-off ≤85: sensitivity = 98%, specificity = 80%), while only minor improvements to the ACE-III's accuracy were observed (AUC = 0.854, 95% CIs [0.744, 0.963], SE = 0.056; optimal cut-off ≤88: sensitivity = 85%, specificity = 75%). CONCLUSION: Overall, both the ACE-III and RBANS are suitable tools for ARBD screening within an alcohol-dependent population, though the RBANS is the superior of the two. Clinicians using these tools for ARBD screening should be cautious of false-positive outcomes and should therefore combine them with other assessment methods (e.g., neuroimaging, clinical observations) and more detailed neuropsychological testing before reaching diagnostic decisions.

ABSTRACT

Conceptual similarities have been identified between experiences of extreme sports athletes and those with drug and behavioral addictions. Evidence suggests rock climbers experience craving and other withdrawal-like states when abstinent from their sport. However, no studies have attempted to quantitatively measure the craving experienced by participants of any extreme sports. Such a measure could allow a greater understanding of the craving experienced by extreme sports athletes and a comparison of these across sports (e.g., surfing) and activities (e.g., drug-use). Therefore, using validated craving measures as a template, the aim of the two studies outlined here was to design and preliminarily validate a subjective multidimensional inventory that could be used to measure craving in the sports of rock-climbing and mountaineering ("RCCQ"). The aim of the first study was to investigate the factor structure of a preliminary measure of craving. Climbers (n = 407) completed the RCCQ. A 3-factor model explained 53.65% of the total variance in item scores. All three factors comprised five items each, which were conceptually labeled as "urge to climb" "negative reinforcement" and "positive reinforcement." The aim of the second study was to validate the 15-item 3-factor RCCQ resulting from Study 1 using confirmatory factor analysis (CFA). Climbers (n = 254) completed the questionnaire under a climbing-related cue condition or a cue-neutral condition. CFA revealed a good model fit and that all individual parameter estimates were significant and standard errors were within reasonable limits once item 13 was removed from Factor 1. Study 1 supports the multi-dimensional nature of rock climbing craving and shows parallels with substance-related craving in reflecting intention and positive (desire) and negative (withdrawal) reinforcement. Study 2 confirms this factor structure and gives initial validation to the measure with evidence that these factors are sensitive to cue exposure. Given the preliminary nature of the data, any practical implications are tentative. However, if as shown here, craving for climbing (and potentially other extreme sports) is similar to that experienced by drug-users and addicts, there is the potential that climbing and other extreme sports could be used as a replacement therapy for drug users.

ABSTRACT

Background: Neuropsychological assessment is central to identifying and determining the extent of Alcohol-Related Cognitive Impairment (ARCI). The present systematic review aimed to synthesize and discuss the evidence appraising the neuropsychological tests used to assess ARCI in order to support clinicians and researchers in selecting appropriate tests for use with this population. Methods: We searched for studies investigating the psychometric, diagnostic and practical values of tools used in the screening, diagnosis, and assessment of Korsakoff's Syndrome (KS), Alcohol-Related Dementia (ARD), and those with a specific diagnosis of Alcohol-Related Brain Damage (ARBD). The following databases were searched in March 2016 and again in August 2018: MEDLINE, EMBASE, Psych-INFO, ProQuest Psychology, and Science Direct. Study quality was assessed using a checklist designed by the authors to evaluate the specific factors contributing to robust and clearly reported studies in this area. A total of 43 studies were included following the screening of 3646 studies by title and abstract and 360 at full-text. Meta-analysis was not appropriate due to heterogeneity in the tests and ARCI samples investigated in the studies reviewed. Instead, review findings were narratively synthesized and divided according to five domains of assessment: cognitive screening, memory, executive function, intelligence and test batteries, and premorbid ability. Effect sizes (d) were calculated to supplement findings. Results: Overall, several measures demonstrated sensitivity to the cognitive deficits associated with chronic alcoholism and an ability to differentiate between gradations of impairment. However, findings relating to the other psychometric qualities of the tests, including those important for the accurate assessment and monitoring of ARCI (e.g., test-retest reliability), were entirely absent or limited. Additionally, the synthesis of neuropsychological outcomes presented here supports the recent impetus for a move away from discrete diagnoses (e.g., KS, ARD) and the distinctions between them toward more broad and inclusive diagnostic conceptualizations of ARCI, thereby recognizing the heterogeneity in presentation. Conclusions: Based on the evidence reviewed, provisional recommendations for appropriate tests in each domain of assessment are presented, though further validation of most tests is warranted. Review findings can support efficient and evidenced-based test-selection and guide future research in this area.

ABSTRACT

Buckley's commentary on our study of rock climber's withdrawal experiences raises a number of important questions surrounding the concept of extreme or adventure sports addiction. Drawing on the few available investigations of this topic, we respond to Buckley's questions here, though emphasize the need for further studies of extreme sports addiction in order to provide more empirically informed answers.

ABSTRACT

Background and aims Extreme sports athletes are often labeled "adrenaline junkies" by the media, implying they are addicted to their sport. Research suggests during abstinence these athletes may experience withdrawal states characteristic of individuals with an addiction (Celsi, Rose, & Leigh, 1993; Franken, Zijlstra, & Muris, 2006; Willig, 2008). Despite this notion, no research has directly explored withdrawal experiences of extreme sports athletes. Methods Using semi-structured interviews, we explored withdrawal experiences of high (n = 4) and average-ability (n = 4) male rock climbers during periods of abstinence. We investigated the psychological and behavioral aspects of withdrawal, including craving, anhedonia, and negative affect; and differences in the frequency and intensity of these states between groups. Results Deductive content analysis indicated support for each of the three categories of anhedonia, craving, and negative affect. Consistent with existing substance addiction literature, high-ability climbers recalled more frequent and intense craving states and negative affect during abstinence compared with average-ability climbers. No differences in anhedonic symptoms between high and average-ability participants were found. Conclusions Rock climbing athletes appear to experience withdrawal symptoms when abstinent from their sport comparable to individuals with substance and behavioral addictions. The implications of these findings and suggestions for future research are discussed.
