Application of Self-Determination Theory to Substance Use and Its Treatment: A Scoping Review of the Literature.

Background: Self-determination theory (SDT) may provide important insights for understanding substance misuse and treatment outcomes. However, to date, the literature applying SDT to substance use and its treatment is varied and difficult to integrate. Methods: The authors searched psycINFO and PubMed on October 26th, 2021 to identify articles applying SDT to substance use and its treatment. Eligible studies were published in peer-reviewed articles in English, on adult populations (18+), and explicitly applied SDT to the context of substance use or its treatment. Results were categorized as studies applying SDT in non-treatment or treatment settings and were synthesized within these categories by substance(s) of focus, primary outcome(s), component(s) of SDT utilized, and relevant findings. Results: The search revealed 38 articles applying SDT in non-treatment (k = 16) and treatment (k = 22) settings. Causality orientations and the basic psychological needs were the most frequently studied components of SDT. Studies that applied SDT in non-treatment settings placed a greater emphasis on causality orientations, whereas treatment studies more frequently targeted or measured basic psychological needs. Conclusions: SDT constructs consistently predicted both substance misuse and treatment outcomes in a theoretically consistent manner, however, several important gaps remain and opportunities for future research are discussed.

Food and alcohol disturbance, alcohol use, and negative consequences among college students engaging in binge drinking: A longitudinal examination of between- and within-person effects.

OBJECTIVE: Researchers have documented robust associations between food and alcohol disturbance (FAD-intoxication; restricting caloric intake before or during alcohol consumption to experience a quicker and/or more intense alcohol intoxication) and alcohol use and related negative consequences. However, most of this research has utilized cross-sectional designs. Consequently, two crucial gaps have not yet been filled: (a) the separation of the relatively stable, between-person and the fluctuating, within-person components in the relations between FAD-intoxication and alcohol-related constructs; and (b) the examination of the directionality of these within-person relations. METHOD: Participants were college students (n = 686) who reported past-month binge drinking. Most participants identified as White (71.3%), female (78.4%), non-Hispanic (87.8%), with a mean age of 20.64 (SD = 3.25). Participants completed three online surveys assessing FAD-intoxication (College Eating and Drinking Behaviors Scale), alcohol use (Daily Drinking Questionnaire), and related negative consequences (Brief Young Adult Alcohol Consequences Questionnaire). RESULTS: Analyses revealed that FAD-intoxication was positively associated with alcohol use and related negative consequences at the between-person level. Additionally, at the within-person level, FAD-intoxication at Time 2 significantly predicted alcohol use at Time 3. Notably, the cross-lagged effect from FAD-intoxication at Time 1 to alcohol use at Time 2 was not significant. FAD-intoxication did not significantly predict negative consequences. Neither use nor consequences significantly predicted FAD-intoxication. CONCLUSIONS: Our results suggest that FAD-intoxication is relevant to the study of alcohol use and related negative consequences and should be considered in interventions targeting alcohol use and related negative consequences among students who endorse binge drinking.

Sexual minority status and food and alcohol disturbance among college students: The moderating role of body esteem.

Food and alcohol disturbance (FAD; restricting caloric intake before, during, or after drinking to either offset calories or to increase intoxication) is common among college students and poses a threat to students' health. In conjunction, sexual minority (SM; i.e., not exclusively heterosexual) college students may be at increased risk of engaging in alcohol misuse and disordered eating compared to their heterosexual peers due to exposure to minority stress. However, little research has examined whether engagement in FAD differs by SM status. Body esteem (BE) is an important resilience factor among SMs that may influence SM students' risk of participating in FAD. Therefore, the aim of the present study was to understand the association between SM status and FAD with additional interest in BE as a moderating factor. Participants were 459 college students who engaged in past 30-day binge drinking. Most participants identified as White (66.7 %), female (78.4 %), heterosexual (69.3 %), with a mean age of 19.60 (SD = 1.54) years. Participants completed two surveys (3 weeks apart) over the course of an academic semester. Analyses revealed a significant interaction between SM status and BE, such that SMs with lower BE (T1) reported more engagement in FAD-intoxication (T2), whereas SMs with higher BE (T1) reported less engagement in FAD-calories (T2) and FAD-intoxication (T2) than their heterosexual peers. Stressors associated with body esteem may contribute to increased FAD engagement among SM students. Consequently, BE may be an especially important target for interventions aimed at reducing FAD among SM college students.

The effectiveness of animal welfare-, environmental-, and health-focused video appeals on implicit and explicit wanting of meat and intentions to reduce meat consumption.

The production of meat and its consumption are associated with negative consequences for the environment, the animals raised and slaughtered for food, and the health of those who consume animal-based foods. We investigated whether video appeals that addressed these topics affected participants' wanting of meat and intentions to reduce meat relative to a control video. Results indicated only the environmental video led to increased intentions to reduce meat relative to controls. Nevertheless, implicit wanting of meat was lower in all three experimental conditions compared to the control condition. Additionally, moral emotions and agreement with the video's message mediated the relationships between condition and implicit wanting and intentions for the animal welfare and environment conditions. For the health condition, only agreement with the message served as a mediator. These results suggest that although animal welfare-, environmental-, and health-focused video appeals may be effective at shifting immediate desire to consume meat, environmental video appeals may be the most effective for increasing intentions to change future meat intake.

Interoceptive attention or merely distraction? An examination of the effects of brief breath counting training on stress-induced alcohol-seeking behavior.

Prior research suggests brief mindfulness (breath counting) interventions may be effective at attenuating stress-induced alcohol-related cravings. However, it remains unclear whether this reduction in craving is due to increased state mindfulness or mere distraction. To test this, the present study examined whether brief breath counting would attenuate a stress-induced increase in the relative value of alcohol in young adult alcohol users, and whether this therapeutic effect was superior to simple distraction (cross counting). University students from England and the United States (N = 278, Mage = 20.2 years, 56.5% females) were randomly assigned to one of four conditions: breath counting, distraction, stress-only, no-stress. Participants first listened to a 6-min audio file training the breath counting technique or control audio, before exposure to 2-min noise stress induction or no-stress during which participants engaged in breath counting, cross counting (distraction), or nothing. The relative value of alcohol was then assessed by preferential choice of alcohol versus food pictures. Results indicated that stress-only augmented alcohol picture choice compared to no-stress, and that this stress induction effect was attenuated to a comparable extent by breath counting and distraction. Group differences in alcohol picture choice washed out in the second half of the choice test. The results suggest that the therapeutic effect of breath counting (interoceptive attention) on stress-induced alcohol-seeking may stem from distraction (cognitive load) rather than a unique state of mindful acceptance. The implications of this lab study for mindfulness therapy are considered. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

Loneliness and Alcohol-Related Problems among College Students Who Report Binge Drinking Behavior: The Moderating Role of Food and Alcohol Disturbance.

Loneliness and alcohol misuse are common among college students and pose a threat to public health. To better understand the longitudinal association between these public health concerns we examined food and alcohol disturbance (FAD; i.e., restricting one's caloric intake prior to drinking) as a moderator in the association between loneliness and alcohol-related problems. Participants were 456 college students from a mid-sized university who engaged in past 30-day binge drinking. The majority of participants identified as being White (67.1%), female (78.1%), and reported a mean age of 19.61 (SD = 1.54) years. Participants completed two surveys (3 weeks apart) over the course of an academic semester. Analyses revealed a significant interaction between loneliness and FAD, such that loneliness (T1) significantly and positively predicted alcohol-related problems (T2), but only among individuals who engaged in relatively higher levels of FAD (T1). FAD may be an appropriate target for interventions aimed at reducing alcohol-related problems among college students experiencing loneliness.

A qualitative examination of college students' perceptions of cannabis: insights into the normalization of cannabis use on a college campus.

ObjectiveThis study aimed to qualitatively examine how perceptions of cannabis differ among college students in an effort to better understand the changing landscape of cannabis on college campuses. Participants: Forty-six predominantly male (69.9%; Mage = 23.15, SD = 4.11) college students attending a border state university (i.e., a state that has not yet legalized cannabis but borders a state that has). Methods: Participants engaged in facilitated focus group discussions (N = 5) about cannabis-related issues. Results: Thematic analysis uncovered three primary themes and six subthemes. Main themes included: 1) User Heterogeneity and Identity, 2) Relative Benefits and Harms of Cannabis, and 3) Social Position of Cannabis on Campus Culture. Conclusions: Cannabis has quickly integrated into the college social environment, with social stigmatization and identification with cannabis impacting decisions to use. Findings inform existing college health programs on how to approach conversations about cannabis with students.

Delaying Gratification's role in the relationship between facets of mindfulness and substance use outcomes.

The present study examined whether five facets of mindfulness (acting with awareness, describing, observing, non-judging of inner experience, and non-reactivity to inner experience) relate to alcohol and cannabis outcomes (quantity of use and negative consequences) via delaying gratification. Participants were college students across seven universities who used alcohol (n = 1467) and/or cannabis (n = 647) in the last 30 days. For the alcohol analytic sample, the majority of students identified as being female (71.1%) and reported a mean age of 20.04 (Median = 19.00; SD = 3.47) years. For the cannabis analytic sample, the majority of students identified as being female (69.7%) and reported a mean age of 19.63 (Median = 19.00; SD = 2.85). Within our model, significant indirect effects were only found for two mindfulness facets. Specifically, the indirect effects from acting with awareness (alcohol indirect ß = -0.026, SE = 0.006; cannabis indirect ß = -0.019, SE = 0.008) and observing (alcohol indirect ß = -0.017, SE = 0.005; cannabis indirect ß = -0.015, SE = 0.007) to consequences via delaying gratification and quantity were significant for both the alcohol and cannabis models, such that acting with awareness and observing were associated with higher delaying gratification; which in turn was associated with lower quantity of use, which in turn was associated with fewer consequences for both the cannabis and alcohol models. Our findings suggest that delaying gratification is important to understanding the relationship between specific mindfulness facets (i.e., acting with awareness and observing) and alcohol and cannabis outcomes. Mindfulness interventions aimed at reducing substance use may benefit from targeting delaying gratification through increasing acting with awareness and observing.

Sexual Minority Status, Affect Lability, and Suicide Ideation: Buffering Role of Trait Mindfulness.

OBJECTIVE: Emotion regulation has been proposed as a mechanism driving sexual orientation disparities in suicide ideation (SI), but little research has examined the role of affect lability in the association of sexual minority identity and SI. As prior research has found trait mindfulness to be associated with lower SI, the objective of the present study was to examine the buffering role of mindfulness in the associations of sexual orientation, affect lability, and SI. METHOD: The present study used a moderated mediation model to examine a cross-sectional dataset consisting of heterosexual (n = 1511) and sexual minority (n = 355) U.S. college students (N = 1866), to examine whether five facets of mindfulness moderated the indirect association of sexual minority identity on SI via affect lability. RESULTS: As predicted, sexual minority identity was associated with higher affect lability, which in turn was associated with higher SI. Acting with awareness (i.e., attending to the present activities), describing (i.e., the ability to verbalize inner experiences), and non-judging (i.e., refraining from judging inner experiences) buffered the indirect association of sexual minority identity on SI via affect lability, such that the indirect association weakened at higher levels of those mindfulness facets. CONCLUSIONS: Our results provide a better understanding of the emotion regulation mechanisms underlying the higher risk of SI among sexual minorities. Future research is needed to examine mindfulness facets as buffers against SI among other communities, and to examine the efficacy of emotion regulation and mindfulness interventions in reducing suicide ideation and other aspects of suicidality (i.e., plans/attempts).HighlightsSexual orientation disparities in suicide ideation (SI) and affect lability.Sexual minority identity linked to higher SI via higher affect lability.Three mindfulness facets attenuated indirect association of identity on SI.

A cross-national examination of cannabis protective behavioral strategies' role in the relationship between Big Five personality traits and cannabis outcomes.

Background: Problematic cannabis use is common among young adults across the world. However, limited research has examined whether etiological models predicting negative consequences are universal.Objective: The present study examined whether the Five-Factor Model of personality (openness, conscientiousness, extraversion, agreeableness, and neuroticism) relates to cannabis outcomes via use of cannabis protective behavioral strategies (PBS) in a cross-national sample of college student cannabis users (i.e., used cannabis in the last 30 days).Method: Participants were 1175 university students (63.27% female) across five countries (United States, Argentina, Spain, Uruguay, and the Netherlands) recruited to complete an online survey.Results: PBS use mediated the associations between personality traits and cannabis consequences, such that higher conscientiousness (ß = .20), agreeableness (ß = .11), and lower emotional stability [i.e., higher neuroticism] (ß = -.14) were associated with more PBS use. Higher PBS use was, in turn, associated with lower frequency of cannabis use (ß = -.32); lower frequency of use was then associated with fewer cannabis consequences (ß = .34). This sequential pathway was invariant across sex, but not countries. Notably, there were a number of differences in links between PBS and cannabis outcomes when comparing countries (e.g., negative associations in the US sample, but positive associations in the Argentina sample).Conclusions: Cannabis PBS mediates the relationship between personality traits and cannabis outcomes, but there are nuanced differences across countries (i.e., relationship between PBS and cannabis outcomes). Overall, students that are low in conscientiousness, agreeableness, and neuroticism and/or report low rates of PBS use may benefit from cannabis PBS-focused interventions that promote utilization of PBS.

Anxiety Symptoms and Alcohol-Related Problems among College Students: A Moderated-Mediation Model of Rumination and Emotion Dysregulation.

OBJECTIVES: Prior research has individually linked rumination, anxiety, and emotion dysregulation to alcohol misuse, but limited research has examined a comprehensive model linking these variables together. The present study tested a moderated-mediation model to examine whether emotion dysregulation moderated the indirect association of anxiety symptoms on alcohol-related problems via ruminative thinking styles. Method: Participants were 448 college students who consumed alcohol in the previous month. A plurality of participants identified as being White, non-Hispanic (40.6%), female (68.6%), and reported a mean age of 22.75 (Median = 20.00; SD = 6.84) years. Results: Brooding and reflection subtypes of ruminative thinking mediated the association between anxiety symptoms and alcohol-related problems with higher rates of anxiety symptoms associated with higher ruminative thinking, which in turn was associated with more alcohol-related problems. Further, the indirect effect of anxiety symptoms on alcohol-related problems through ruminative thinking was stronger for individuals who reported high levels of emotion dysregulation compared to those with average and low levels of emotion dysregulation. Conclusions: In support of prior work, our results suggest that ruminative thinking, particularly brooding and reflection, are key mechanisms through which anxiety symptoms relate to problematic alcohol use, especially among individuals with high emotion dysregulation. Additional work is needed to test whether decoupling the associations between negative emotional states and ruminative thinking among college students with high emotion dysregulation is a viable intervention target to reduce problematic alcohol use.

Microaggressions and Psychological Health Among College Students: A Moderated Mediation Model of Rumination and Social Structure Beliefs.

Racial microaggressions are common experiences for students of color on college campuses. Given prior research connecting microaggressions to negative mental health outcomes, it is important to better understand the social context and process through which microaggressions are associated with poorer mental health. In addition, we put forth a psycho-sociological approach to microaggressions, integrating an attention to both individual psychology and broader social structure. Specifically, the present study investigated whether the indirect association of school/workplace microaggressions and internalizing symptoms (i.e., depression, anxiety, and stress) through problem-focused thoughts (a subset of ruminative thinking) differed as a function of horizontal and vertical dimensions of individualism and collectivism among a racially diverse sample of non-White college students (n = 549) from two universities in the USA. As hypothesized, problem-focused thoughts mediated the associations between school/workplace microaggressions and all three negative mental health symptoms. Furthermore, the indirect effect of school/workplace microaggressions on psychological health through problem-focused thoughts was stronger in students with high levels of vertical individualism (i.e., autonomous but recognize/accept inequality among individuals), compared to students with low or average levels. Our findings suggest that students of color who endorse vertical individualism are at a relatively greater risk of negative mental health outcomes related to school/workplace microaggressions via problem-focused thoughts. Future research is needed to examine additional factors that may buffer or strengthen the pathways between microaggressions and negative mental health in students of color.

College alcohol beliefs and negative alcohol-related consequences: A moderated mediation model of enhancement drinking motives and restricted eating.

College alcohol beliefs (CABs; i.e., beliefs that alcohol use is an integral feature of college life) have been shown to be positively associated with negative alcohol-related consequences among college students. Given this information, the present study examined restricted eating before consuming alcohol to increase intoxication as one drinking behavior mechanism through which CABs relate to negative alcohol-related consequences. Additionally, we examined whether the indirect association of CABs and negative alcohol-related consequences through restricted eating differed as a function of enhancement drinking motives, specifically the CABs-restricted eating association (i.e., first-stage moderated mediation). Participants included college students (n = 1347) across 10 states/universities who consumed alcohol in the last month. The majority of participants identified as being White, non-Hispanic (69.0%), female (70.1%), and reported a mean age of 20.92 (Median = 20.00; SD = 4.60) years. As hypothesized, restricted eating mediated the association between CABs and negative alcohol-related consequences. Further, the indirect effect of CABs on negative alcohol-related consequences through restricted eating was stronger in students who endorsed high levels of enhancement motives, compared to students with low or average levels. Our findings suggest that college students with high levels of enhancement motives are at a relatively higher risk of experiencing negative alcohol-related consequences related to CABs via restricted eating, compared to those with average or low levels. Future research is needed to examine additional drinking-related factors that may influence the pathways between CABs and negative alcohol-related consequences among college students.
