RESUMEN

Previous work identified the operation of an attentional bias (AB) towards healthy food related stimuli among those with increasing tendencies towards orthorexia nervosa (ON) using a modified Stroop task. The current work aimed to replicate and extend our understanding of this effect by incorporating alternative measures of AB (i.e., the dot probe task) and ON (i.e., the Teruel Orthorexia Scale [ToS]) in a sample of self-defined vegans/vegetarians. The theoretical assertion of the ToS is the conceptual broadening of orthorexia with differentiable dimensions - one characterised as a "healthy" preoccupation with healthy food/eating patterns (HeOr) and the other by a more underlying pathology (OrNe). This study also aimed to examine the pattern of responding across these two dimensions according to factors known to predict ON. Eighty-six participants (mean age = 33.0 years; 20 males, 66 females) completed measures of obsessive compulsivity, perfectionism, state/trait anxiety and ToS as well as a dot probe designed to measure AB for healthy and unhealthy-related food stimuli, threat ratings of each of words utilized and perceived identity centrality as a vegan/vegetarianism. Results showed a dissociation of predicted determinants for "healthy" ON (HeOr) and pathological ON (OrNe). HeOr was predicted by increasing identity centrality whereas OrNe was predicted by increased OCD and perfectionism, and increased interference for healthy-related food words (in particular slowed disengagement) and not unhealthy related food words. Threat-related ratings of unhealthy food words was shown to be common across both dimensions. This pattern highlights cognitive and individual differences-based correlates of pathological and non-pathological ON.

RESUMEN

BACKGROUND: Health messages on e-cigarette packs emphasise nicotine addiction or harms using similar wording to warnings on cigarette packs. These may not be appropriate for e-cigarettes which constitute a reduced risk alternative for smokers. This research aimed to (1) develop and test a selection of relative risk messages for e-cigarette products; (2) compare these to the two current EU Tobacco Products Directive (TPD) nicotine addiction messages; and (3) explore differences between smokers, non-smokers and dual users. METHOD: Twenty-six messages focusing on either harm-reduction or cessation were developed and rated by multidisciplinary experts for accuracy, persuasiveness and clarity. The eight highest ranking messages were compared alongside the TPD messages in a sample of 983 European residents (316 smokers, 327 non-smokers, 340 dual users) on understandability, believability and convincingness. RESULTS: On all three constructs combined, the two TPD messages rated the highest, closely followed by four relative risk messages "Completely switching to e-cigarettes lowers your risk of smoking related diseases", "Use of this product is much less harmful than smoking", "Completely switching to e-cigarettes is a healthier alternative to smoking", and "This product presents substantially lower risks to health than cigarettes" which did not differ statistically from the TPD messages. Non-smokers rated TPD1 significantly higher overall than dual users. Dual users rated "This product is a safer alternative to smoking" significantly higher than non-smokers. Messages did not differ on understandability. CONCLUSIONS: These alternative messages provide a useful resource for future research and for policy makers considering updating e-cigarette product labelling.

RESUMEN

The psychological and social effects of the COVID-19 pandemic are pervasive, and there is potential for a long-lasting impact on mental health. In the current study, we sought to provide, in a representative sample of UK residents during the third COVID-19 lockdown in February 2021, further evidence for the validation of the COVID-19 anxiety syndrome construct. We did this by evaluating the COVID-19 anxiety syndrome against measures of personality, health anxiety and COVID-19 anxiety in predicting levels of generalized anxiety and depression and by examining whether increased health anxiety and COVID-19 psychological distress (COVID-19 anxiety and COVID-19 anxiety syndrome) scores were associated with increased attentional bias to COVID-19-related stimuli. A series of correlation analyses revealed that neuroticism, health anxiety, COVID-19 anxiety and COVID-19 anxiety syndrome scores were positively and significantly correlated with generalized anxiety and depression scores and that the perseveration component of the COVID-19 anxiety syndrome predicted generalized anxiety and depression scores independently of age, gender, conscientiousness, openness, health anxiety and COVID-19 anxiety. Furthermore, results indicated that only the total COVID-19 anxiety syndrome score and the scores on the avoidance and perseveration components were positively and significantly correlated with attentional bias indices. More specifically, the general attentional bias index was only shown to be positively and significantly correlated with the total COVID-19 anxiety syndrome score and its perseveration component, while slowed disengagement was only shown to be negatively and significantly correlated with the total COVID-19 anxiety syndrome score and its avoidance component. The implications of these findings are discussed.

RESUMEN

PURPOSE: It has been argued that orthorexia nervosa (ON) is a unique type of disordered eating of food considered by the individual to be healthy. Given that in other eating disorder populations attentional preference for food-related cues influences eating behaviours, is it also likely that these biases may be a characteristic of ON tendency. METHODS: Eighty healthy individuals completed the ORTO-15 questionnaire (ON tendency), a modified Stroop task containing words related to healthy and unhealthy foods and perceived hunger levels pre- and post-testing. The ORTO-15 was used to identify participants within this sample who demonstrated more or less of the characteristics of ON. RESULTS: Results suggest that the presence of attentional bias to healthy, but not for unhealthy food-related stimuli independently predict increased ON tendency. Increased attentional bias towards healthy food-related stimuli is associated with increased scores on the ORTO-15. CONCLUSION: Attentional bias, as a deficit in information processing, towards healthy food-related stimuli accounts for variability in ON characteristics. LEVEL OF EVIDENCE: Level I, experimental study.

RESUMEN

We sought to explore the motivations for pre-partying amongst UK student drinkers who reported pre-partying at least once per month. Two distinct educational settings were included: colleges, where the majority of students are below the legal age for drinking, and university, where all students would be legally allowed to drink. A cross-sectional correlational design was adopted. Ninety-four college (16-18 years) and 138 university students (18-28 years) from the UK completed an online survey, of whom 54.7% and 86.9% reported pre-partying at least once per month, respectively. Alcohol use was measured using the Alcohol Use Disorders Identification Test - Consumption (AUDIT-C) and pre-partying motivations were assessed using the Pre-partying Motivations Inventory (PMI). Frequency of pre-partying behavior and the number of units consumed was also recorded. Hierarchical regression analyses showed that, for college students, AUDIT-C positively predicted pre-partying frequency, while gender and AUDIT-C positively predicted the units of alcohol consumed but Barriers to Consumption (BC) negatively predicted units consumed. Among university students AUDIT-C and Interpersonal Enhancement predicted pre-partying frequency, and AUDIT-C predicted the amount of pre-partying units consumed. Different motives for pre-partying motives were identified across two distinct educational settings. The finding that BC negatively correlated with the amount of alcohol consumed amongst younger college students requires further study, as it contradicts previous work in this area, but is consistent with findings that availability predicts alcohol intake. Understanding differences in drinking behavior between age groups is a key finding, which will allow future research to track developmental influences on the effectiveness of interventions.

RESUMEN

PURPOSE: Food craving has been shown to induce states of psychological challenge, indexed by increases in adrenaline but not cortisol production. The study aimed to test the relationship between challenge and (1) desire thinking (the active processing of the pleasant consequences of achieving a desired target and planning how to do so) and (2) craving. METHODS: Participants (N = 61) self-reported their levels of craving and desire thinking. They were then presented with situations in which their craving would be fulfilled or not via a false feedback practice task (a wordsearch task). During this period psycho-physiological measures of challenge and threat were taken. RESULTS: Higher levels of craving were linked to challenge only when the craved object was likely to be obtained. Whilst anticipating reward fulfillment, higher levels of craving were linked to higher levels of desire thinking. In turn, higher levels of desire thinking were related to lower levels of challenge. In contrast, during the processes of reward fulfillment, desire thinking was linked to increased challenge (i.e., a positive indirect effect). CONCLUSIONS: Craving is linked to increased levels of psychological challenge when the object of the craving can be obtained, but it is unrelated to craving when it is not. The research also highlights the importance of desire thinking as an important, but complex, mediator in the relationship between craving and motivational states: desire thinking inhibited challenge when anticipating craving fulfillment, but encouraging it during the process of fulfillment itself. LEVEL OF EVIDENCE: I: Evidence obtained from at least one properly designed randomized controlled trial.

RESUMEN

AIMS: To review the effectiveness of responsible drinking messages (RDMs). METHODS: We searched PsycINFO, MEDLINE and Google Scholar to June 2016 for studies evaluating the effectiveness of RDMs. Only eight studies met the inclusion/exclusion criteria. Due to a small number of search results and broad inconsistency in methods and outcome measures, quantitative synthesis was not possible so a narrative summary of findings was conducted. RESULTS: A review of findings from these articles suggested a disjointed approach in terms of the format and content of RDMs evaluated, as well as the dependent variables used to judge their effectiveness. An overall pattern emerged suggesting that RDMs may have beneficial effects across various outcome measures, including reducing prospective alcohol use. However, due to the inconsistent approach to both the development and evaluation of RDMs, it was not possible to draw any clear conclusions in terms of effectiveness, or indeed the potential size of any effects. CONCLUSIONS: A systematic approach to the development and evaluation of RDMs is recommended to ensure that a clearer evidence base is established in this area, particularly in light of the substantial public funds which are often spent on RDM campaigns. SHORT SUMMARY: A systematic review of studies evaluating the effectiveness of responsible drinking message campaigns reveals an inconsistent approach to message design and evaluation. Findings of the review suggest the need for a more consistent approach to aid in the development of a clearer evidence base in this area.

RESUMEN

AIMS: Responsible drinking messages (RDMs) are used as a key tool to reduce alcohol-related harms. A common form of RDM is in a poster format displayed in places such as bars, bus stops and toilet cubicles. However, evidence for the effectiveness of RDMs remains limited. Moreover, it is not known how environmental contexts (e.g. the number of alcohol-related cues in the environment) impact how such RDMs are interacted with, nor how this in turn affects their efficacy. METHODS: One hundred participants completed a pseudo taste preference task in either in a bar laboratory (alcohol cue rich environmental context) or a traditional laboratory. The walls of the laboratory displayed either RDM or control posters during this task and eye tracking was used to assess participant attention to the posters. RESULTS: Participants looked at the RDM posters less in the bar laboratory where the environmental context is rich in alcohol cues compared to a traditional laboratory where alcohol cues are sparse. Neither poster type or environmental context affected the amount of 'alcohol' consumed and the amount of visual attention given to RDMs was unrelated to the amount of 'alcohol' consumed. CONCLUSIONS: These findings provide experimental evidence that RDMs do not influence drinking behaviour in the direction intended (reduced consumption in situ). In addition, locating RDMs in alcohol-cue rich environments may result in sub-optimal behavioural responses to the RDM materials (e.g. visual attention to content). To maximize the potential impact of RDMs, the optimal location for RDMs is in environments where pre-existing alcohol cues are sparse to non-existent. SHORT SUMMARY: Responsible drinking messages (RDMs) aim to reduce alcohol consumption, however, the findings of this study show that they may not influence in situ consumption. These findings also suggest that the optimal location for RDMs is in environments with few or no other alcohol-related cues.

RESUMEN

The aim of this study was to evaluate the effectiveness of a new psychological intervention, the iNEAR, which is a resilience and wellbeing programme consisting of a classroom based set of activities designed to facilitate the formation of positive identities through the acquisition of skills for growth and personal flourishing. Three hundred and fifty-four young people aged 11 and 12, matched for age and gender, were randomly allocated to the intervention (84 girls; 80 boys) and control conditions (93 girls; 96 boys). Following the intervention, boys, compared to girls, showed higher levels of wellbeing and environmental mastery, and higher levels of tolerance to uncertainty. The intervention was effective in increasing appreciation of positive relationships with others, for girls, and, although not statistically significant, it generated change in the desired direction for boys. In contrast to boys, girls' scores on openness to diversity also increased between baseline and post-intervention. Ways in which positive psychology interventions can resource individuals to better respond to adversity, coercion, and personal uncertainty, and so contribute to safeguarding against the adoption of extreme belief systems are also discussed.

RESUMEN

BACKGROUND/AIMS: If sexual compulsivity and other addictive behaviours share common aetiology, contemporary proposals about the role of attentional processes in understanding addictive behaviours are relevant. METHODS: To examine attentional biases for sex-related words among sexually active individuals and the relationship between sexual compulsivity and sexual behavioural engagement with attentional bias, 55 sexually active individuals completed a modified Stroop task and the sexual compulsivity scale. RESULTS: Findings showed attentional bias towards sex-related stimuli among sexually active participants. In addition, among those with low levels of sexual compulsivity, levels of attentional bias were the same across all levels of sexual experience. Among those with higher levels of sexual compulsivity, greater attentional bias was linked with lower levels of sexual experience. CONCLUSION: Attentional preference for concern-related stimuli varies as a function of the interaction between how long a person has been active sexually and how compulsive their sexual behaviour is.

RESUMEN

Previous research exploring cognitive biases in bulimia nervosa suggests that attentional biases occur for both food-related and body-related cues. Individuals with bulimia were compared to non-bulimic controls on an emotional-Stroop task which contained both food-related and body-related cues. Results indicated that bulimics (but not controls) demonstrated a cognitive bias for both food-related and body-related cues. However, a discrepancy between the two cue-types was observed with body-related cognitive biases showing the most robust effects and food-related cognitive biases being the most strongly associated with the severity of the disorder. The results may have implications for clinical practice as bulimics with an increased cognitive bias for food-related cues indicated increased bulimic disorder severity.

RESUMEN

Behavioural and cognitive pathways that lead to the activation and escalation of craving have been studied extensively. Conversely, limited efforts have been directed towards understanding how craving relates to motivational systems and neuroendocrine responses. These can be understood using the biopsychosocial model of challenge and threat. In the current study, forty participants with varying levels of chocolate craving undertook two word searches, with the prospect of winning a piece of chocolate. Amongst those with high levels of craving, participation in this task led to motivational states of challenge relative to those with lower levels. This was reflected by changes in cardiac reactivity driven by differences in sympathetic-adrenal-medullar and hypothalamic-pituitary-adrenal axis activation. This finding suggests that craving can be associated with states of motivational challenge and thus affect cardiac reactivity.

RESUMEN

Work has identified that metacognitive thought results in desire-based thinking and perpetuates the magnitude and severity of maladaptive behaviour including problematic social media use, and also that one's ingroup identity is related to increasing problematic behaviour. No evidence has ascertained the relative contribution of these as related differential factors in the experience of problematic social media use. The current study explored the comparative importance of components of desire thinking, positive and negative metacognitions and dimensions of ingroup identity on degree of problematic use among 147 current Instagram users. Results showed that for predicting general problematic Instagram use negative metacognitive beliefs and the verbal perseverance component of desire-based thinking were significant. Importantly, however, different factors appeared to be important for predicting distinct aspects of problematic Instagram. For compulsivity indicators, negative metacognitions and verbal perseveration were essential, whereas for the withdrawal component identity centrality (and no other dimensions of identity) and imaginal prefiguration emerge as the sole independent predictors.

RESUMEN

Harmful drinking is associated with significant negative health and social outcomes, but drinkers are reticent to recognise personal drinking problems, hindering natural recovery or help-seeking. Recent evidence suggests that social identity as a drinker is associated with various drinking-related factors but has not been examined in relation to likelihood of problem recognition. In a group of ninety-six harmful drinkers (61 females, M age = 34 years) we explored how identity components associated with ingroup self-investment and ingroup self-definition in combination with implicit identity as a drinker accounted for degrees of problem recognition. In addition to demographic information, addiction experience and drinking behaviour (AUDIT), respondents completed measures of ingroup self-investment (identity centrality, solidarity, and satisfaction), ingroup self-definition (ingroup homogeneity and self-stereotyping), a "self as drinker" identity implicit association test and problem recognition (four items from the Stages of Change Readiness and Treatment Eagerness Scale). After controlling for possible covariates (age, gender and alcohol addiction experience) increased problem recognition was accounted for by explicit and not implicit identity components. More specifically, increasing perceived chronic saliency of one's drinker identity (self-investment in the drinker ingroup) and not an implicit association between the self and being a drinker was related to increased likelihood of problem recognition. This suggests that how chronically and explicitly accessible the identity of the drinker is for individuals might operate to stimulate the willingness or motivation to recognise potential drinking related harm.

RESUMEN

Few studies have examined whether specific aspects of group identification predict problematic and non-problematic addictive behaviours and none have focused on gambling. Applying Leach et al.'s (2008) hierarchical model of in-group identification, we tested the associations between components of self-investment (satisfaction, solidarity, and centrality) and components of self-definition (individual self-stereotyping, in-group homogeneity) on distinguishing between problem and non-problem gambling (n = 10,157) and on the severity of problematic gambling behaviour (n = 2,568). Results showed that (i) in-group-based identities are important in predicting problematic vs. non-problematic gambling behaviours; (ii) in-group-based identities are important in predicting the severity of problematic gambling; (iii) how self-invested an individual is with their in-group and aspects associated with self-definition processes are both important predictors; (iv) perceptions related to how chronically salient one's group membership is for the self (centrality) are essential features of the self-investment mechanism; and (v) self-stereotypical beliefs about one's essential similarities to the prototypical gambling group member norm are fundamental for the defining oneself as a gambler.

RESUMEN

RATIONALE: Witnesses who discuss a crime together may report details that they did not see themselves but heard about from their co-witness. Co-witness information may have beneficial and harmful effects on memory accuracy depending on whether the information was correct or incorrect. OBJECTIVES: Given the prevalence of intoxicated witnesses, it is imperative to understand how alcohol influences this effect. METHODS: The present study asked pubgoers (n = 67) at varying levels of intoxication to recall a mock crime video after having also watched a video witness statement containing both correct and false information. RESULTS: Increased intoxication was associated with decreased confidence, completeness and accuracy, but no increased tendency to report false information. Exposure to incorrect post-event information (PEI) can lead to the incorporation of incorrect information, whereas exposure to correct PEI increased accuracy, regardless of individuals' alcohol intoxication status. CONCLUSIONS: Thus, whilst discussion and intoxication can negatively impact eyewitness memory, discussion may also have benefits for both sober and intoxicated witnesses.

RESUMEN

Memory conformity may occur when a person's belief in another's memory report outweighs their belief in their own. Witnesses might be less likely to believe and therefore take on false information from intoxicated co-witnesses, due to the common belief that alcohol impairs memory performance. This paper presents an online study in which participants (n = 281) watched a video of a mock crime taking place outside a pub that included a witness either visibly consuming wine or a soft drink. Participants then read a statement from the witness that varied in the number of false details it contained before being asked to recall the crime. We found that the intoxicated witness was regarded as significantly less credible, but participants were not less likely to report misinformation from them. This suggests that intoxication status impacts one's perception of how credible a source is, but not one's ability to reject false suggestions from this source. Our findings reinforce the importance of minimizing co-witness discussion prior to interview, and not to assume that people automatically (correctly or not) discount information provided by intoxicated co-witnesses.

RESUMEN

OBJECTIVE: Previous research suggests that exposure to alcohol primes (i.e., stimuli associated with alcohol) affects drinkers' perceptions and behaviors. The present study investigated the effects of an environmental alcohol prime (being in a simulated bar setting) and a safe sex message prime (a public health safe sex message) on sexually active alcohol drinkers. METHOD: Participants (n = 80) were assigned to one of four conditions according to priming allocation and engaged in a simulated video chat with a potential partner. They reported their sex-related self-perceptions and perceptions of a potential partner upon procedural completion. RESULTS: The alcohol-related environmental prime led participants to rate their potential partner as being significantly less inhibited and more sexual. The safe sex message significantly reduced reported sex-related self-perceptions and perceptions of their partners' disinhibition. There was a significant effect of primes on participants' perceptions of their partner's friendliness--participants exposed to either or both prime(s) perceived their partner as being friendlier than participants exposed to no prime. CONCLUSIONS: Results suggest that environmental alcohol primes may strengthen sexually active drinkers' perceptions of a potential partner's disinhibition and sexuality even before alcohol consumption begins, and that a safe sex message may moderate these effects. The presence of safe sex messages in alcohol-related environments may positively influence sexual risk decision making among sexually active drinkers.

RESUMEN

Flicker-induced change blindness paradigms have been used to explore attentional biases for a range of concern-related cues. However, previous studies have had limitations related to concerns about carryover effects in repeated measures designs, as well as problems with response modalities. The present article develops a repeated measures paradigm utilising nonverbal responses and explores the implications of these design modifications for the reliability and validity of the paradigm. Affective stimuli were presented to participants, and the results suggest that the modified paradigm is a useful tool for assessing attentional bias. A number of recommendations for the future use of this methodology are made.

RESUMEN

Desire thinking (voluntary thinking involving a perseverative focusing on desired target-related memories, images, and information), is an important factor in the experience of drinking urges and cravings. Research has not examined the relationship between desire thinking, behavioural intention and the implementation of that behaviour into action, nor how one's past repeated behaviour in situ (expressed as habit) may moderate these relationships. We employed an ad libitum drinking paradigm to provide indirect measures of in-the-moment drinking behaviours (amount poured [mls] and amount consumed [mls]) in a group of eighty-eight self-defined social drinkers immediately after measuring self-reported drinking habit, drinking-related desire thinking, and general drinking behaviour. Results confirmed the predicted positive relationship between desire thinking and in-the-moment drinking behaviour with the effects increasing as a function of rising drinking habit strength. We also observed a dissociation between desire thinking components (verbal perseveration and imaginal prefiguration) in the moderating effects of habit strength on drinking behaviour. For imaginal prefiguration (thoughts related to construction of mental images of a desired target or of its context for consumption) a direct effect on drinking behaviours was shown. In comparison, the effect for verbal perseveration (repetitive self-talk regarding the need to achieve a desired target) was not shown to independently predict drinking-related behaviour but was significantly moderated by increasing drinking-related habit strength. Future work should formulate the nature of this moderating influence on perseverative goal-directed thinking.
