Related metacognitions, desire thinking and identity differentially predict compulsion and withdrawal symptoms in problematic Instagram use.

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.

Does identity as a drinker predict problem recognition motivation in harmful drinkers?

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.

Components of identity expression in problem and non-problem gamblers.

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.

Would you believe an intoxicated witness? The impact of witness alcohol intoxication status on credibility judgments and suggestibility.

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.

Individual differences in selective attentional bias for healthy and unhealthy food-related stimuli and social identity as a vegan/vegetarian dissociate "healthy" and "unhealthy" orthorexia nervosa.

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.

The effects of alcohol and co-witness information on memory reports: a field study.

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.

(Safe) Sex on My Mind: The Effects of a Safe Sex Prime and an Alcohol Prime on Sex-Related Perceptions and Behavior.

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.

Development and testing of relative risk-based health messages for electronic cigarette products.

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.

The COVID-19 anxiety syndrome and selective attentional bias towards COVID-19-related stimuli in UK residents during the 2020-2021 pandemic.

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.

Does alcohol-related desire thinking predict in-the-moment drinking behaviours?

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.

The intoxicated co-witness: effects of alcohol and dyadic discussion on memory conformity and event recall.

RATIONALE: Co-witness discussion is common and often witnesses are under the influence of alcohol. As such, it is important to understand how such factors may influence eyewitness testimony. OBJECTIVES: We combined a co-witness memory paradigm with an alcohol administration paradigm to examine the influence of alcohol and dyadic discussion on remembering a mock crime. METHODS: Intoxicated and sober dyads discussed a previously seen video, whilst in a control condition sober and intoxicated individuals recalled the event on their own. Unknown to the dyads, each discussion partner saw a different version of the video including unique details not present in the other video version. All participants then engaged in a second individual recall attempt. RESULTS: Dyads were more likely to recall misleading details in their individual recall attempts compared to the control group. Intoxicated and sober dyads were equally likely to report misleading information. Alcohol intoxication had no negative impact on individuals' ability to correctly identify the source of their responses. Intoxicated participants recalled fewer details under free recall conditions. Alcohol had a detrimental effect on participants' confidence in their free recall accounts. CONCLUSIONS: Possible alcohol-related and social-cognitive mechanisms are discussed which may contribute to the current findings as well as applied implications for interviewing intoxicated witnesses.

Comparison of Allen Carr's Easyway programme with a specialist behavioural and pharmacological smoking cessation support service: a randomized controlled trial.

BACKGROUND AND AIMS: A combination of behavioural and pharmacological support is judged to be the optimal approach for assisting smoking cessation. Allen Carr's Easyway (ACE) is a single-session pharmacotherapy-free programme that has been in operation internationally for 38 years. We compared the effectiveness of ACE with specialist behavioural and pharmacological support delivered to the national standard in England. DESIGN: A two-arm, parallel-group, single-blind, randomized controlled trial. SETTING: London, UK, between February 2017 and May 2018. PARTICIPANTS: A total of 620 participants (310 in ACE and 310 in the combined behavioural and pharmacological support condition) were included in the analysis. Adult (≥ 18 years) smokers wanting to quit were randomized in a 1 : 1 ratio. Mean age for the total sample was 40.8 years, with 53.4% being male. Participant baseline characteristics (ethnicity, educational level, number of previous quit attempts, nicotine dependence) were evenly balanced between treatment groups. INTERVENTION AND COMPARATOR: The intervention was the ACE method of stopping smoking. This centres on a 4.5-6-hour session of group-based support, alongside subsequent text messages and top-up sessions if needed. It aims to make it easy to stop smoking by convincing smokers that smoking provides no benefits for them. The comparator was a specialist stop smoking service (SSS) providing behavioural and pharmacological support in accordance with national standards. MEASUREMENTS: The primary outcome was self-reported continuous abstinence for 26 weeks from the quit/quit re-set date verified by exhaled breath carbon monoxide measurement < 10 parts per million (p.p.m.). Primary analysis was by intention to treat. Secondary outcomes were: use of pharmacotherapy, adverse events and continuous abstinence up to 4 and 12 weeks. FINDINGS: A total of 468 participants attended treatment (255 ACE versus 213 SSS, P < 0.05). Of those who did attend treatment, 100 completed 6-month measures (23.7% ACE versus 20.7% SSS). Continuous abstinence to 26 weeks was 19.4% (60 of 310) in the ACE intervention and 14.8% (46 of 310) in the SSS intervention [risk difference for ACE versus SSS 4.5% (95% confidence interval (CI) = -1.4 to 10.4%, odds ratio (OR) = 1.38)]. The Bayes factor for superiority of the ACE condition was 1.24. CONCLUSION: There was no clear evidence of a difference in the efficacies of the Allen Carr's Easyway (ACE) and specialist smoking cessation support involving behavioural support and pharmacotherapy.

Selective attentional bias to food-related stimuli in healthy individuals with characteristics towards orthorexia nervosa.

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.

Context-specific drinking and social anxiety: The roles of anticipatory anxiety and post-event processing.

Individuals with clinically elevated social anxiety are especially vulnerable to alcohol-related problems, despite not drinking more than those with less anxiety. It is therefore important to identify contexts in which socially anxious persons drink more to inform intervention efforts. This study tested whether social anxiety was related to greater drinking before, during, or after a social event and whether such drinking was related to the psychosocial factors anticipatory anxiety or post-event processing (PEP; review of the social event). Among past-month drinkers, those with clinically elevated or higher social anxiety (HSA; n = 212) reported more anticipatory anxiety, more pre-event drinking to manage anxiety, and PEP than those with normative or lower social anxiety (LSA; n = 365). There was a significant indirect effect of social anxiety on pre-drinking via anticipatory anxiety. Social anxiety was related to more drinking during the event indirectly via the serial effects of anticipatory anxiety and pre-drinking. Unexpectedly, PEP did not mediate or moderate the relation between social anxiety and post-event drinking. In sum, anticipatory anxiety was related to more drinking before, during, and after a social event and HSA drinkers were especially vulnerable to drinking more to manage this anxiety, which increased drinking before and during the event. This effect was specific to anticipatory anxiety and not evident for another social anxiety-specific risk factor, PEP. Thus, anticipatory anxiety may be an important therapeutic target for drinkers generally and may be especially important among HSA drinkers.

Communicating the relative health risks of E-cigarettes: An online experimental study exploring the effects of a comparative health message versus the EU nicotine addiction warnings on smokers' and non-smokers' risk perceptions and behavioural intentions.

INTRODUCTION: This study investigated the effects of the European Union Tobacco Products Directive [EU-TPD] Article 20 E-cigarette (EC) health warnings ("This product contains nicotine which is a highly addictive substance. [It is not recommended for non-smokers.]") and a comparative harm message ("Use of this product is much less harmful than smoking" [COMP]) on smokers' and non-smokers' perceptions and behavioural intentions. METHODS: 2495 UK residents (1283 smokers and 1212 non-smokers) self-reported perceived harm, addictiveness, EC effectiveness, social acceptability, and intentions to purchase and use EC, and in smokers, intentions to quit and intentions to use EC in future quit attempts. These were measured before and after exposure to EC images containing either the TPD, COMP, TPD + COMP or no message. RESULTS: Non-smokers had higher harm, addictiveness and lower social acceptability perceptions. TPD presence increased, whilst COMP decreased, harm and addictiveness perceptions in both groups. For smokers only, harm perceptions were lower following exposure to COMP alone vs. no message. For non-smokers the TPD increased harm perceptions vs. no message. There were no effects on social acceptability, EC effectiveness or use intentions. In smokers only, purchase and quit intentions were higher following exposure to the COMP alone. CONCLUSION: TPD messages may be effective smoking prevention tools, although the COMP message was more effective in reducing harm perceptions and increasing use intentions in smokers. That COMP did not increase use intentions in non-smokers suggest that such exposures may potentially act as an effective harm reduction tool without resulting in increased uptake among non-smokers.

Survey of the effect of viewing an online e-cigarette advertisement on attitudes towards cigarette and e-cigarette use in adults located in the UK and USA: a cross-sectional study.

OBJECTIVES: This study explored the potential for e-cigarette advertisements to (1) enhance attitudes towards cigarettes and/or (2) reduce barriers to e-cigarettes uptake. The study tested whether exposure to an online electronic cigarette advertisement changed attitudes towards cigarettes and e-cigarettes in smokers, non-smokers, e-cigarette users and dual users (smokers who also use e-cigarettes). DESIGN: Cross-sectional study SETTING: Online survey PARTICIPANTS: Adults (n=964) aged 18 to 65 years old (M=36 years, SD=11.6) from the UK and USA. Participants were grouped into current non-smokers, e-cigarette users, dual users and smokers. INTERVENTIONS: Participants viewed 1 of 15 randomly assigned online e-cigarette advertisements. PRIMARY MEASURES: Three single seven-point Likert scales measuring health, desirability, social acceptability were completed pre and post advertisement exposure. RESULTS: Post exposure all smoking groups showed a decrease or no change in how socially acceptable or desirable they rated cigarettes. Paradoxically, dual users rated cigarettes as being significantly healthier after viewing the advertisement (p=0.01) while all other smoking group ratings remained the same. There was an increase or no change in how all smoking groups perceived the healthiness and desirability of e-cigarettes CONCLUSIONS: We observed no evidence that exposure to an e-cigarette advertisement renormalises or encourages smoking in smokers, non-smokers or e-cigarette users. However, there is some indication that viewing an e-cigarette advertisement may increase duals users' perceptions of the health of smoking.

Pre-partying Amongst Students in the UK: Measuring Motivations and Consumption Levels Across Different Educational Contexts.

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.

Desire thinking as a predictor of drinking status following treatment for alcohol use disorder: A prospective study.

Research has indicated that craving is one of the strongest predictors of treatment outcome and relapse in Alcohol Use Disorders (AUD) but there is little consensus on the factors that may influence its activation and escalation. Research has also shown that desire thinking is an important cognitive process which may exacerbate craving in problem drinkers. The aim of present study was to explore, for the first time, the role of desire thinking in prospectively predicting relapse, craving and binge drinking in patients receiving treatment for AUD. One hundred and thirty-five patients admitted to two rehabilitation centres and two outpatient services for addiction and mental health problems were administered baseline, treatment completion and three months follow-up measures of anxiety and depression, AUD severity, binge drinking frequency, craving and desire thinking. Results indicated that the verbal perseveration component of desire thinking at treatment completion was the only significant predictor of relapse at follow-up over and above baseline AUD severity and binge drinking frequency. Furthermore, the imaginal prefiguration component of desire thinking and craving levels at treatment completion were found to predict craving levels at follow-up independently of AUD severity and binge drinking frequency at baseline. Finally, both the imaginal prefiguration and verbal perseveration components of desire thinking at treatment completion were found to be the only predictors of binge drinking frequency at follow-up independently of AUD severity and binge drinking frequency at baseline. Treatments for AUD should aim to reduce desire thinking in people to enhance clinical outcomes and reduce relapse risk.

Tales of hope: Social identity and learning lessons from others in Alcoholics Anonymous: A test of the Social Identity Model of Cessation Maintenance.

Social identities can facilitate positive recovery outcomes for people overcoming addiction. However, the mechanism through which such protective effects emerge are unclear. The social identity model of cessation maintenance posits that one such process may be contextualisation (the creation of meaning around relevant future events and actions which act in a protective fashion). The current paper tested the role of contextualisation by exploring the role of a common feature of addiction meetings, the sharing of a personal recovery story. Data were collected from an online sample of 170 members of Alcoholics Anonymous [AA] (mean age 45.4 years, 50% male). Participants rated their social identification with AA before reading an archetypal tale of hope. They then completed measures of contextualisation (the perceived self-relevance and utility of the tale) and measures of perceived quit efficacy and costs of relapse to self and others. Identity, relevance and utility positively related to quit efficacy and perceived cost of relapse to the self. High identification with AA was also related to higher story relevance and utility. However, no mediation relationship between identity and efficacy via story relevance or utility was observed. Perceived cost to self increased in line with identity, with an additional joint indirect mediation of social identity via both meditators. These findings provide a clear pattern of results linking identity to contextualisation (story relevance and utility) and contextualisation to outcome measures. They also support the role of contextualisation as an important component of group processes more generally.

The effects of food craving and desire thinking on states of motivational challenge and threat and their physiological indices.

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.
