Impact of Legalization on Cannabis Use, Attitudes, and Purchasing Preferences: A Repeated Cross-Sectional Survey of Canadian Young Adults.

Objective: The Government of Canada legalized recreational cannabis use in October of 2018 with the implementation of the Cannabis Act. The act aimed to reduce the illicit cannabis market, improve consumer health outcomes, and reduce youth access to cannabis. However, little is known about the attitudes and behaviors of young adults, who have been shown to have a high prevalence of cannabis use, towards cannabis after legalization. Method: In this descriptive study, we examined cannabis use, attitudes, and purchasing preferences among Canadian university-attending young adults both before and after the legalization of cannabis. Participants were recruited from a large Canadian university from 2017 to 2021. Results: Our findings showed that there was an increase in cannabis use immediately following legalization that subsequently decreased in later years. Additionally, attitudes about the legalization of cannabis became more favorable in later years (following legalization), particularly among those who did not use cannabis. Most young adults were also keen to purchase cannabis from a government-owned store before legalization. However, with the exception of past-month consumers, this preference decreased substantially following legalization. Conclusions: The current research adds to the knowledge base about changes in cannabis-related attitudes and use after legalization and focuses on a key population - young adults.

The Long Shadow of Addiction-Related Nostalgia: Nostalgia Predicts Ambivalence and Undermines the Benefits of Optimism in Recovery.

Background: Previous research has shown that nostalgia for the pre-addicted self can motivate people living with addiction to engage in behavior change. Objective: Herein, we explored nostalgia for the addictive behavior-labeled addiction-related nostalgia (ARN)-among people in recovery from engaging in addictive behavior. We tested the novel idea that ARN is positively associated with ambivalence about recovery. We also hypothesized that ARN may counteract the positive influence of optimism on individuals' commitment to recovery. Results: In two studies involving individuals in recovery from a gambling (Study 1; N=301) or alcohol use disorder (Study 2; N=604), ARN was linked to increased ambivalence about recovery, while optimism was associated with decreased ambivalence. As expected, the interaction between optimism and ARN revealed that nostalgia either eliminated (Study 1) or reduced (Study 2) the negative relation between optimism and ambivalence. Conclusions: These findings underscore the challenges posed by ARN in the recovery process and emphasize the importance of interventions that address and mitigate its impact while considering the moderating role of optimism.

The utility of nostalgia for unhealthy populations: A systematic review and narrative analysis.

Nostalgic reverie (i.e. sentimental longing) has received increased attention as a predictor of health and well-being, but only a handful of reviews have summarized this literature. The available reviews (Dementia: The International Journal of Social Research and Practice, 19, 2020, 330; Intimations of nostalgia: Multidisciplinary explorations of an enduring emotion, Bristol University Press, 2022) left a critical gap in explicating the function of nostalgia among people engaged in unhealthy behaviour. In the current systematic review and narrative analysis, we sought to answer whether and under what conditions emotion serves to help or hinder people engaged in unhealthy behaviours in terms of taking action to change. We identified 14 studies and categorized them into two themes. In Theme I, nostalgising about a time in one's life when one was healthier motivated both readiness to change and action to change unhealthy behaviour. In Theme II, nostalgizing about the perceived benefits of engaging in unhealthy behaviour (e.g. social connectedness related to drinking) was associated with the continuance or acceleration of the unhealthy behaviour. This review highlights not only the presence of a link between nostalgia and unhealthy behaviour but also that the content of one's nostalgising matters for understanding whether the unhealthy behaviour is undermined or bolstered.

A synthesis of evidence for policy from behavioural science during COVID-19.

Scientific evidence regularly guides policy decisions1, with behavioural science increasingly part of this process2. In April 2020, an influential paper3 proposed 19 policy recommendations ('claims') detailing how evidence from behavioural science could contribute to efforts to reduce impacts and end the COVID-19 pandemic. Here we assess 747 pandemic-related research articles that empirically investigated those claims. We report the scale of evidence and whether evidence supports them to indicate applicability for policymaking. Two independent teams, involving 72 reviewers, found evidence for 18 of 19 claims, with both teams finding evidence supporting 16 (89%) of those 18 claims. The strongest evidence supported claims that anticipated culture, polarization and misinformation would be associated with policy effectiveness. Claims suggesting trusted leaders and positive social norms increased adherence to behavioural interventions also had strong empirical support, as did appealing to social consensus or bipartisan agreement. Targeted language in messaging yielded mixed effects and there were no effects for highlighting individual benefits or protecting others. No available evidence existed to assess any distinct differences in effects between using the terms 'physical distancing' and 'social distancing'. Analysis of 463 papers containing data showed generally large samples; 418 involved human participants with a mean of 16,848 (median of 1,699). That statistical power underscored improved suitability of behavioural science research for informing policy decisions. Furthermore, by implementing a standardized approach to evidence selection and synthesis, we amplify broader implications for advancing scientific evidence in policy formulation and prioritization.

This time with feeling: In-play sports betting as a vehicle for emotion regulation.

OBJECTIVE: The purpose of this research was to assess factors (i.e., emotion regulation, impulsivity) that motivate in-play sports betting. Specifically, we examined whether individuals report increased excitement after placing an in-play bet and whether trait negative and positive urgency moderate the effect of emotion regulation motives on in-play betting frequency. METHOD: Three cross-sectional studies were conducted, each following a major sporting event: Superbowl LVI (56) (Study 1), March Madness Final (Study 2), and Union of European Football Associations Champions League Final (Study 3). Participants were U.S. (NStudy 1 = 111; NStudy 2 = 121) and U.K. (NStudy 3 = 239) residents who reported placing at least one in-play bet during the respective sporting events. Participants completed self-report measures of excitement, emotion regulation motives, in-play betting frequency, problem gambling, and trait affective impulsivity. Data from the three studies were pooled to conduct an integrative data analysis (IDA). RESULTS: Participants reported increased excitement after placing an in-play bet (p < .001). In bivariate analyses, greater emotion regulation motives were associated with greater in-play betting frequency (p < .05). In moderation analyses, emotion regulation motives interacted with trait negative (p < .001) and positive urgency (p < .001) to predict in-play betting frequency, such that the bivariate effects were amplified among those higher (relative to lower) in trait affective impulsivity. CONCLUSIONS: In-play sports betting is an exciting activity that people who gamble may engage in to regulate their emotions. These effects are amplified in those with high trait affective impulsivity. Responsible gambling tools such as mandatory play breaks may discourage the continuation of impulsive betting episodes.

Exploring potential moderators of depressive symptoms and treatment outcomes among patients with opioid use disorder.

BACKGROUND: Depressive symptoms are common in patients seeking medication treatment for opioid use disorder (MOUD treatment) and decrease quality of life but have been inconsistently related to opioid treatment outcomes. Here, we explore whether depressive symptoms may only be related to adverse treatment outcomes among individuals reporting high opioid use-related coping motives (i.e., use of opioids to change affective states) and high trait impulsivity, two common treatment targets. METHODS: Patients seeking MOUD treatment (N = 118) completed several questionnaires within two weeks of their treatment intake. Treatment outcomes (opioid-positive urine screens and days retained in treatment) were extracted from treatment records. Moderation analyses controlling for demographic characteristics and main effects were conducted to explore interaction effects between depressive symptoms and two distinct moderators. RESULTS: Depressive symptoms were only related to opioid use during early treatment among patients reporting high opioid use-related coping motives (B = 2.67, p =.004) and patients reporting high trait impulsivity (B = 2.01, p =.039). Further, depressive symptoms were only inversely related to days retained among individuals with high opioid use-related coping motives (B = -10.12, p =.003). CONCLUSIONS: Individuals presenting to treatment with opioid-related coping motives and/or impulsivity in the context of depressive symptoms may confer unique risk for adverse treatment outcomes. Clinicians may wish to consider these additive risk factors when developing their treatment plan.

Collective nostalgia as a balm for the distressed social identity.

Group history provides the experiential building blocks that shape social identity. When contemporary events are perceived as having created (or creating) a discontinuity with that history, collective nostalgia is likely to be elicited. Importantly, collective nostalgia is functional-it consolidates social identity, motivating group members to support a return to the group's "true" state of existence. However, no group is a monolith. Factions within a group may have differing opinions on what aspects of the past best represent core features of the ingroup. Variations in the content of the collective nostalgia can cleavage members' responses. Herein, we review research demonstrating the powerful role collective nostalgia and its contents play in intra- and intergroup relations, especially in the socio-political domain.

Advancing the Pathways Model: Financially Focused Self-concept and Erroneous Beliefs as Core Psychopathologies in Disordered Gambling.

In the Pathways Model, there are three distinct etiological subtypes of disordered gambling (Behaviourally Conditioned, Emotionally Vulnerable, and Anti-Social Impulsive Risk-Taker). The Pathways Model also posits that erroneous gambling beliefs are a maintenance factor of disordered gambling across the subtypes. Yet, etiological factors and erroneous beliefs have largely been examined separately when determining disordered gambling subtype. Moreover, there may be heretofore unexamined maintenance factors that span the disordered gambling subtypes. In the current research, we addressed this gap by using latent profile analyses to assess the role both erroneous beliefs and financially focused self-concept (a novel maintenance factor) play in the determination of disordered gambling subtype. In Study 1, community members with gambling problems (n = 215) completed the Gambling Pathways Questionnaire and Financially Focused Self-Concept Scale. In Study 2 (n = 290), participants also completed the Gambling Beliefs Questionnaire. Results from both studies revealed three profiles that coincide with the subtypes in the Pathways Model as providing the best fit to the data. The three profiles were largely distinguished by low, medium, or high scores on the etiological factors, which is consistent with the disordered gambling subtypes being on different parts of the same continuum of psychopathology severity. Financial focus (Studies 1 and 2) and erroneous gambling beliefs (Study 2) were elevated across the three profiles, and both were higher among profiles with more severe psychopathology. Findings support a dimensional understanding of gambling disorder psychopathology and suggest that a financially focused self-concept may be a maintenance factor of disordered gambling.

Self-Generated Motives of Social Casino Gamers.

Social casino games have achieved widespread popularity, and are accessed by more than 85 million people each day. Yet, why people play social casino games is largely unknown. To address this gap, an inductive approach was taken to better understand the motives for playing social casino games, as well as the motives for transitioning from social casino gaming to gambling and vice versa. To this end, 269 social casino gamers were asked to provide a ranked list of their motives for playing social casino games. Additionally, we asked participants their motivations for transitioning from gambling to social casino gaming (n = 202) or vice versa (n = 67). A total of 795, 605, and 201 unique responses describing motives for playing social casino games, transitioning from social casino gaming to gambling, and transitioning from gambling to social casino gaming, respectively, were analyzed using a thematic content analysis. The most frequently endorsed motive for playing social casino games was for enhancement (e.g., fun, challenge). Participants also noted playing to earn rewards, including money, and for social reasons. Several motives linked social casino game play to gambling. These included: to hone gambling-related 'skills', a desire to transition to gambling to win real money, and as a gambling harm-reduction strategy. Motives for playing social casino games did not differ significantly between those who first gambled and then transitioned to social casino gaming and vice versa, suggesting that once people begin playing social casino games, they have similar motives for continued engagement. The present study contributes to understanding the immense popularity of social casino games and their links to gambling.

The distinct associations of ingroup attachment and glorification with responses to the coronavirus pandemic: Evidence from a multilevel investigation in 21 countries.

While public health crises such as the coronavirus pandemic transcend national borders, practical efforts to combat them are often instantiated at the national level. Thus, national group identities may play key roles in shaping compliance with and support for preventative measures (e.g., hygiene and lockdowns). Using data from 25,159 participants across representative samples from 21 nations, we investigated how different modalities of ingroup identification (attachment and glorification) are linked with reactions to the coronavirus pandemic (compliance and support for lockdown restrictions). We also examined the extent to which the associations of attachment and glorification with responses to the coronavirus pandemic are mediated through trust in information about the coronavirus pandemic from scientific and government sources. Multilevel models suggested that attachment, but not glorification, was associated with increased trust in science and compliance with federal COVID-19 guidelines. However, while both attachment and glorification were associated with trust in government and support for lockdown restrictions, glorification was more strongly associated with trust in government information than attachment. These results suggest that both attachment and glorification can be useful for promoting public health, although glorification's role, while potentially stronger, is restricted to pathways through trust in government information.

Understanding Lower-Risk Cannabis Consumption from the Consumers' Perspective: A Rapid Evidence Assessment.

Background: In the current rapid evidence assessment, we summarize the existing research on lower-risk cannabis consumption as understood by those who consume cannabis. Methods: We identified 7111 unique articles published between 1900 and 2021 using search terms related to a) cannabis consumption, b) beliefs and behaviors, and c) positive outcomes. Results: Twelve articles met our inclusion criteria. Three themes emerged that reflect lower-risk cannabis beliefs and behaviors (informed self-regulation, protective behavioral strategies, and the normalization of cannabis consumption) and one theme reflected motivations that undermine lower-risk cannabis consumption (e.g., using cannabis to cope). Conclusions: Results suggest a need for targeted lower-risk cannabis consumption research-research focused on how those who consume cannabis do so in a positive, non-problematic manner. Such research would help to inform policy and practice and, ultimately, help promote lower-risk cannabis consumption strategies.

In time, we will simply disappear: Racial demographic shift undermines privileged group members' support for marginalized social groups via collective angst.

The racial demographic shift occurring in many Western countries provides a unique context to study the reactions of a high-power group (White people) to the potential loss of their privileged position in society. Three experiments (N = 77, N = 302, N = 555) conducted in Canada, the US, and the UK showed that White people who are reminded about the ongoing demographic changes and who see race relations as a zero-sum game whereby any gains by minorities must come at the expense of the majority, experience stronger collective angst and, to a lesser extent, fear (but not anger). In turn, collective angst, but not the other negative group-based emotions, fuels their motivation to protect the existing intergroup hierarchy by withdrawing support for progressive social movements and increases anti-immigration sentiments. Downregulating the existential threat experienced by White majorities in the face of a racial demographic shift may be one way to reduce acrimonious behavioral intentions aimed at preserving their place in the social hierarchy.

Trust in scientific information mediates associations between conservatism and coronavirus responses in the U.S., but few other nations.

U.S.-based research suggests conservatism is linked with less concern about contracting coronavirus and less preventative behaviors to avoid infection. Here, we investigate whether these tendencies are partly attributable to distrust in scientific information, and evaluate whether they generalize outside the U.S., using public data and recruited representative samples across three studies (Ntotal = 34,710). In Studies 1 and 2, we examine these relationships in the U.S., yielding converging evidence for a sequential indirect effect of conservatism on compliance through scientific (dis)trust and infection concern. In Study 3, we compare these relationships across 19 distinct countries. Although the relationships between trust in scientific information about the coronavirus, concern about coronavirus infection, and compliance are consistent cross-nationally, the relationships between conservatism and trust in scientific information are not. These relationships are strongest in North America. Consequently, the indirect effects observed in Studies 1-2 only replicate in North America (the U.S. and Canada) and in Indonesia. Study 3 also found parallel direct and indirect effects on support for lockdown restrictions. These associations suggest not only that relationships between conservatism and compliance are not universal, but localized to particular countries where conservatism is more strongly related to trust in scientific information about the coronavirus pandemic.

Commentary on "Different roles of interpersonal trust and institutional trust in COVID-19 pandemic control".

An increasing number of epidemiologic studies have identified trust as a social determinant of COVID-19 mortality. Trust influences public compliance with policies aimed at containing the pandemic through physical distancing, wearing masks, and vaccine uptake. However, whilst some forms of trust are public assets (e.g., trust in government), others might be liabilities (e.g., trust in close friends and family members). Contributing to this body of work, Lou et al. (2022) examined associations of trust with COVID-19 fatality rates and willingness to get tested for COVID-19. Using correlation analyses, behavioral experiments, and agent-based modeling, they found institutional trust predicted lower COVID-19 fatality rates and greater willingness to get tested. In contrast, interpersonal trust predicted the speed with which COVID-19 was controlled in the early stages of the pandemic and people's willingness to obey norms preventing the spread of the virus (e.g., decreased nonessential outdoor activity). Investigations such as this offer useful knowledge to public health officials on ways to mitigate a pandemic. This commentary examines the pivotal role of social science in pandemic control, which up to now has been underfunded and overshadowed by the race to develop vaccines. We also highlight the importance of theory, particularly in research on trust, to producing evidence that is replicable and meaningful for policy application.

Mental Health Over Time and Financial Concerns Predict Change in Online Gambling During COVID-19.

This study examined online gambling behavior during COVID-19 land-based gambling restrictions and associations with changes in mental health, impacts on household income due to the pandemic, financially focused motivations, and symptoms of gambling problems. A repeated online survey was administered to adult gamblers in Ontario, Canada. Wave 1 was conducted at the beginning of the first COVID-19 lockdown (April 2020) and wave 2 in August 2020. Respondents (N = 940) completed validated self-report questionnaires related to depression and anxiety, financial motivation, financial impacts due to the pandemic, online gambling behaviors, and problem gambling symptomatology. A cluster analysis identified three subgroups: no online gambling (subgroup 1), engagement in a range of gambling games online and change in gambling involvement (i.e., some increased and some decreased gambling; subgroup 2), and predominantly online lottery play with no change in online gambling (subgroup 3). Respondents who reported increased anxiety and depression symptom severity between the two waves and those who experienced greater symptoms of problem gambling and negative impacts on household income due to COVID-19 were most likely to be found in subgroup 2. Greater financial focus was also noted in this group. Results indicate a link between change in online gambling involvement during COVID-19 and increased mental health problems, elevated problem gambling severity, negative impacts on household income, and a greater financially focused self-concept. These results may help generate novel research questions examining short and long-term effects of the pandemic on online behaviors that inform policy and practice.

Explaining reinforcement and erroneous beliefs in pathological exercise: A commentary and expansion on Coniglio et al. (in press) using the pathways model of disordered gambling.

Coniglio, Cooper, and Selby proposed that behavioral reinforcement may be critical for understanding the etiology and maintenance of pathological exercise among people living with anorexia nervosa. They presented three competing hypotheses about why exercise can become problematic: (a) positive reinforcement via biological and behavioral rewards, (b) negative reinforcement via avoidance of aversive states, or (c) a synergistic interplay between positive and negative reinforcement. Herein, we extend Coniglio and colleagues' framework by drawing on theory and research from the field of disordered gambling-a behavior in which reinforcement is an etiological and maintaining mechanism. We applied the pathways model of disordered gambling to the study of pathological exercise and made the following two proposals. First, pathological exercise may be driven by positive reinforcement, negative reinforcement, or both (they are not mutually exclusive), depending on the presence or absence of specific co-occurring psychopathologies. Second, erroneous beliefs about the safety and efficacy of maladaptive exercise for weight control may help maintain pathological exercise regardless of the type of reinforcement. We conclude by calling for research that assesses Coniglio and colleagues' novel hypotheses and our supposition that the pathways model can help provide a framework for those hypotheses.

Perfectionism predicts disordered eating and gambling via focused self-concept among those high in erroneous beliefs about their disordered behavior.

BACKGROUND AND AIMS: Perfectionism, a focused self-concept, and erroneous beliefs have been implicated in the development and maintenance of various disordered behaviors. However, researchers have yet to examine how these factors combine to explain different disordered behaviors. Herein, we addressed this gap and hypothesized a moderated-mediation model whereby perfectionism fosters the development of disordered behaviors through a focused self-concept. Critically, the effect of a focused self-concept on disordered behaviors is specific to people with erroneous beliefs about their disordered behaviors. The model was tested in the contexts of disordered gambling and disordered eating, particularly dietary restraint. METHOD: In Study 1, participants were community members who gamble (N = 259). In Study 2, participants were university women (N = 219). In both studies, participants completed self-report measures of all constructs that are both reliable and valid. RESULTS: In Study 1, as expected, there was a positive association between perfectionism and disordered gambling, which was mediated by financially focused self-concept. This mediation was only observed among participants who scored high on illusion of control and belief in luck. Likewise, in Study 2, there was a positive association between perfectionism and dietary restraint, which was mediated by appearance focused self-concept. The mediation effect was only observed among participants who believed that maladaptive dietary restraint behaviors were safe and efficacious. DISCUSSION AND CONCLUSIONS: The findings support the transdiagnostic utility of our model, which may help explain an array of disordered behaviors, including other addictive behaviors as well as behaviors that involve rigid adherence to rules and control.
