Development of the Substance Use Motives Measure (SUMM): A comprehensive eight-factor model for alcohol/drugs consumption

Dual-substance use disorder couples: An integrative review and proposed theoretical model

Committed romantic relationships between two individuals with Substance Use Disorder (or dual-SUD couples) are prevalent. Dual-SUD couples have poor treatment engagement and outcomes. Research has established a reciprocal link between relationship dynamics (e.g., conflict, intimacy) and substance use. Thus, the couple's relationship presents a distinct social context for both partner's substance use. Dual-SUD couples face unique challenges due to substance use being a shared behavior that may serve as a rewarding source of compatibility, closeness, and short-term relationship satisfaction despite it being at the cost of other alternative sources of substance-free reinforcement. Yet, treatment options for these couples are scarce. Dual-maladaptive health behaviors (e.g., dual-substance use) are challenging to treat; however, theory and preliminary research suggests that transformation of couple's joint motivation toward adaptive health behavior change may result in a more satisfying relationship and improved treatment outcomes for both individuals. The current paper reviews the extant literature on dual-SUD couples from theoretical, empirical, and treatment research and proposes an expanded paradigm regarding how we understand dual-SUD couples with the aim of informing basic research and treatment development.

Types of psychoactive substance and manifested risky sexual behaviors among men - a review

Purpose

Determining the relationship between the use of types of psychoactive substance and risky sexual behavior among men. The sources cited in the manuscript were selected through a search of scientific article databases in July 2023. Priority was given to publications with release dates from 2018-2023. Publications in Polish and English were included.

Views

The phenomenon of chemsex, more and more often noted in the group of men who have sex with men (MSM), involving sexual activity under the influence of intoxicants, promotes risky sexual behavior. The drugs used for these practices are mainly stimulants, disinhibitors and anesthetics. Factors that increase the risk of an individual deciding to engage in chemical sex include not accepting his sexual preferences, feelings of guilt, personality traits characterizing a person prone to taking risks and with a tendency to seek sensations, as well as high scores on the scale of depressiveness. The main factor determining the emergence of the problem is the occurrence of minority stress.

Conclusions

There is a relationship between the use of a certain type of psychoactive substance and engaging in risky sexual behavior. Psychoactive substances help to overcome fear and reduce the impact of minority stress on MSM. Risky behaviors undertaken during chemsex include increasing the risk of contracting diseases through the lack of appropriate safeguards, the risk of addiction, prostitution, as well as threats social relationships and mental health.

Distal and proximal risk factors of problematic cannabis use associated with psychotic-like experiences

BACKGROUND

Problematic cannabis use is associated with endorsement of psychotic-like experiences (PLEs) in non-clinical samples. However, little is known in regard to predictors of this relationship, which may be relevant to prevention and intervention. In the present research, we investigate impulsivity and cannabis use motives as potential distal and proximal risk factors for PLEs using conditional process analysis.

METHODS

Using an online cross-sectional survey of N = 300 students, we assessed endorsement of PLEs using the Community Assessment of Psychic Experiences (CAPE), problematic cannabis use with the Cannabis Use Disorder Identification Test (CUDIT-R), motivations for using cannabis with the Substance Use Motives Measure, and impulsivity using the Urgency and Premeditation, Perseverance, Sensation Seeking, Positive Urgency Impulsive Behaviour Scale (UPPS-P).

RESULTS

All three subscales on the CAPE were associated with significantly higher scores on the CUDIT-R. Before and after covarying for sex, we found that higher CUDIT-R scores mediated the relations between lack of perseverance and negative urgency impulsivity with higher PLE symptoms. Furthermore, the indirect effect of cannabis use on the relationship between lack of perseverance and high negative PLE symptoms was only significant at high and moderate levels of depression-coping, but not at low depression-coping motives.

CONCLUSION

Impulsivity and depression-coping motives may be distal and proximal psychological risk factors for negative PLEs in the context of problematic cannabis use. Our findings are in line with the broader substance use and mental health literature and may be informative for cannabis use treatment targets.

Impulsivity mediates the association between narcissism and substance-related problems beyond the degree of substance use: a longitudinal observational study

BACKGROUND

Narcissism has been implied as a putative risk factor for substance use disorders (SUDs). However, previous research did not disentangle the degree of substance use from substance-related problems, the symptoms of SUDs. This preregistered study addressed the open question whether grandiose and vulnerable narcissism and their constituent traits convey specific SUD risk, that is, explain substance-related problems beyond the degree of use. Furthermore, we tested whether impulsivity or substance use motives linked to narcissistic self-regulation mediate this association.

METHODS

Narcissism, impulsivity, substance use motives, past-year substance use, and substance-related problems were assessed in 139 (poly-)substance users, 121 of whom completed a one-year follow-up. For significant longitudinal associations between narcissism factors and substance-related problems controlled for the degree of use, we tested impulsivity and substance use motives as mediators.

RESULTS

Grandiose narcissism (r =.24, p =.007) and its constituent factors antagonistic (r =.27, p =.003) and agentic narcissism (r =.18, p =.050), but not vulnerable narcissism, prospectively predicted substance-related problems beyond the degree of substance use. Associations of grandiose narcissism and antagonistic narcissism with substance-related problems were fully mediated by impulsivity, but not substance use motives. Impulsivity explained roughly one third of the association of both grandiose (P̂M = 0.30) and antagonistic narcissism (P̂M = 0.26) with substance-related problems.

DISCUSSION

We demonstrate that grandiose narcissism- particularly antagonistic but also agentic narcissism- is specifically linked to substance-related problems beyond the degree of substance use. The mediating effect of impulsivity but not substance use motives suggests that impulsivity may be a more important mechanism than narcissistic self-regulation in promoting SUD in narcissism. However, future studies may use more targeted measures than substance use motives to further probe the role of self-regulation. Similar result patterns for alcohol compared to all substances together indicate that mechanisms may be alike across substances. In conclusion, narcissistic individuals may not use substances more but have a higher SUD risk, informing prevention and treatment.

Individual Differences in Substance Use Motives, Trauma, and Stress Among College-Based Polysubstance Users

Background: Co-use of alcohol and other drugs within a certain time frame (i.e., polysubstance use) has become increasingly prevalent, particularly among college-aged individuals, but understanding motives for co-use remains limited. Polysubstance use has been associated with a higher likelihood of negative health consequences as compared to single substance use. Objectives: The current study examined associations between motivations for using alcohol, tobacco, and cannabis among college students who use multiple substances versus students using only one substance or no substances. Additionally, we examined the effect of trauma and daily stress on polysubstance use in self-report data from individuals (N=134) participating in the MAPme Study. Results: First, the observed prevalence of polysubstance use was greater than expected by chance, with most individuals co-using alcohol and cannabis. "Alcohol and Other Drug Users" were more frequently motivated to drink for social (β=0.27, CI=[0.07, 0.44]), enhancement (β=0.26, CI=[0.01, 0.42]) and coping (β=0.21, CI=[0.06, 0.47]) reasons compared to individuals who consumed alcohol alone. Conclusions: Individual differences in motivations for use were partly explained by frequency of alcohol use and alcohol problem severity, but not by history of trauma or stress. Finally, while patterns of correlations among motivations for use across substances suggested a general tendency to be motivated to use substances for similar reasons, this was not supported by confirmatory factor models. Overall, shared motives may inform potential behavioral patterns for co-use of substances during college and might advise future treatment efforts.

Development of the Enthusiastic Substance Use Attitudes Scale: Preliminary Evidence of a Novel Maintenance Factor

Background: Expectancies, motives, and attitudes toward substances are cognitive factors that partially account for substance use; however, existing measures tend to have monotonous phrasing, diverging from the enthusiastic attitude toward the perceived benefits of substance use exhibited by those who use substances regularly in informal settings. Objective: I aimed to characterize a new cognitive maintenance factor that precedes substance use by creating a brief, multidimensional measure to capture this tone nuance, which I called the Enthusiastic Substance Use Attitudes Scale (ESUAS). Method: Undergraduate students (n = 198) between ages 18 and 62 (M = 19.15, SD = 3.65; 66.2% women; 71.71% White) completed the study for course credit. Results: I used exploratory and confirmatory factor analyses to reduce a 90-item item pool based on a comprehensive qualitative thematic analysis of social media, traditional media, and the scientific literature to an 18-item hierarchical bifactor model. This model contained nine specific factors, which are (1) sociability, (2) enjoyment, (3) physical health, (4) mental health, (5) relaxation, (6) personal growth, (7) performance enhancement, (8) boredom, and (9) life processing; two general factors, which are (1) substance-induced emotion regulation and (2) substance-based assistance; and a higher-order single factor above the nine specific factors - resulting in twelve highly internally consistent, empirically supported scales. Further, the ESUAS demonstrated excellent structural, convergent, divergent, incremental, and diagnostic validity. The degree of enthusiasm towards substance use positively related to substance use disorder symptomology, polysubstance use, neuroticism, and difficulty with regulating emotions while negatively relating to one's psychological quality of life and agreeableness. Conclusion: The ESUAS may be an effective tool for professionals to characterize these enthusiastic attitudes further and measure a more ecologically valid view of the perceived benefits of substance use among those who use substances, thereby developing a more compassionate, non-stigmatizing understanding within the general public, advancing medicinal uses of illicit substances, and improving conceptualizations and treatments.

Confirming Eight-Factor Structure of the Substance Use Motives Measure in a Sample of US College Students

The 2020 National Survey on Drug Use indicates nearly three quarters of individuals ages 18-25 have used substances in the past year. Research suggests individuals who use substances to cope with negative mood states are typically more substance-involved, report more psychological distress, and have a more extensive treatment history. Additionally, the high rate of polysubstance use among substance using adults in the U.S. highlights the need for broadband measures that can adequately capture use, consequences, and motivations for use of multiple substances. However, most measures assessing motives for use are typically substance specific. Recently, Biolcati and Passini (2019) developed a brief, but comprehensive model of broad substance use motives (i.e., Substance Use Motives Measure, SUMM) based on well-established motives questionnaires (e.g., DMQ-R, MMQ). They found support for their proposed eight-factor model in an online sample of Italian citizens (ages 18-60). No studies to date have examined the psychometric properties of the SUMM with an English-speaking or US college student sample. The current study evaluates the factor structure of the SUMM in a sample of 143 college students (74.8% female, 77.6% White, and 94.4% non-Hispanic/Latinx) at a large, southeastern university in the United States. Results of a confirmatory factor analysis showed support for the previously identified eight-factor structure for the SUMM, with acceptable model fit and internal consistency of each factor found. Findings support using the SUMM as a broad measure of substance use motives, but more research is needed to assess measurement invariance across different groups and to evaluate external, concurrent, and convergent validity using other well-established measures of substance use motives, severity, and psychiatric symptomatology.

Patterns of Event-Level Concurrent Substance Use During Sex Among Gay, Bisexual, and Other Men Who Have Sex with Men in Metro Vancouver

This study identified patterns of sexualized substance use among gay, bisexual, and other men who have sex with men (gbMSM) and examined associated risk factors for sexually transmitted and blood borne infections (STBBI). Data were from a longitudinal cohort recruited using respondent-driven sampling between Feb-2017 and Feb-2019. Participants reported on events with up to five of their most recent sexual partners. Latent class analysis examined patterns of concurrent substance use 2 h prior to or during sex. Multinomial regression identified demographic, partner-level, and event-level factors associated across 11,877 sexual events reported by 757 participants. Most combinations of substance use were rare, but most drugs were frequently combined with other drugs when they were used prior to or during a sexual event. Six latent classes of concurrent event-level substance use were identified. The referent class (58.8% of events) was characterized by limited use of any drugs. The Common Drug Use class (12.1%) was characterized by use of alcohol, cannabis, and poppers and the Licit Drug Use class (21.6%) was characterized by use of alcohol alone. The Party 'N' Play (PnP) class (2.3%) was characterized by use of crystal methamphetamine GHB, Poppers, and Erectile Drugs; The Multi-use (3.5%) class was characterized by the PnP substances plus alcohol and ecstasy; and the Cannabis + class was characterized by use of Cannabis, Erectile Drugs, and Ecstasy. Relative to the referent class, all other classes were associated with events with more behavioural and network risk factors for STBBIs-highlighting the need for harm reduction interventions for gbMSM who use these drugs.

The Building Emotional Awareness and Mental health (BEAM) program developed with a community partner for mothers of infants: protocol for a feasibility randomized controlled trial

BACKGROUND

Drastic increases in the rates of maternal depression and anxiety have been reported since the COVID-19 pandemic began. Most programs aim to improve maternal mental health or parenting skills separately, despite it being more effective to target both concurrently. The Building Emotional Awareness and Mental health (BEAM) program was developed to address this gap. BEAM is a mobile health program aiming to mitigate the impacts of pandemic stress on family well-being. Since many family agencies lack infrastructure and personnel to adequately treat maternal mental health concerns, a partnership will occur with Family Dynamics (a local family agency) to address this unmet need. The study's objective is to examine the feasibility of the BEAM program when delivered with a community partner to inform a larger randomized controlled trial (RCT).

METHODS

A pilot RCT will be conducted with mothers who have depression and/or anxiety with a child 6-18 months old living in Manitoba, Canada. Mothers will be randomized to the 10 weeks of the BEAM program or a standard of care (i.e., MoodMission). Back-end App data (collected via Google Analytics and Firebase) will be used to examine feasibility, engagement, and accessibility of the BEAM program; cost-effectiveness will also be examined. Implementation elements (e.g., maternal depression [Patient Health Questionnaire-9] and anxiety [Generalized Anxiety Disorder-7]) will be piloted to estimate the effect size and variance for future sample size calculations.

DISCUSSION

In partnership with a local family agency, BEAM holds the potential to promote maternal-child health via a cost-effective and an easily accessible program designed to scale. Results will provide insight into the feasibility of the BEAM program and will inform future RCTs. TRIAL REGISTRATION {2A}: This trial was retrospectively registered with ClinicalTrial.gov ( NCT05398107 ) on May 31st, 2022.

COVID-related stress and substance use: examining the role of sleep disturbance

The current investigation employed a cross-sectional design to evaluate the associations of COVID-19 stress, sleep disturbance, and substance use among a national sample of 143 adults (57.3% male, Mage = 38.5 years, SD = 11.28), surveyed at a single time-point using Amazon's MTurk platform. We hypothesized that COVID-19-related stress would be indirectly related to substance use outcomes (i.e. number of substance classes used daily, number of alcoholic drinks per occasion, substance use coping motives; but not substance use enhancement motives) through sleep disturbance severity. As expected, results indicated that the models examining indirect effects were statistically significant for number of substance classes used daily and substance use coping motives. However, there was no evidence that sleep disturbance explained the relation between COVID-19-related stress and number of alcoholic drinks per occasion or substance use enhancement motives. These findings underscore the importance of sleep disturbance in efforts to better understand how COVID-19-related stress is associated with certain types of substance use behavior.

Validation of the Motivational Inventory Underlying Substance Use Engagement (MI-USE)

Given the growing number of fatalities associated with the use of multiple types of drugs, there is an urgent need for a tool that allows clinicians and researchers to quickly assess diverse reasons for substance use. Here, we sought to validate the Motivational Inventory Underlying Substance Engagement (MI-USE), a new measure that assesses motivations for use across different types of substances. Participants were 538 adults ages 18-60 (48% women) who reported substance use problems and past-year drug or alcohol use. Analyses were conducted to discover and validate the factor structure of the MI-USE and evaluate its construct validity. A 30-item model best fit the MI-USE, with one General Factor capturing overall motivation to engage in substance use and eight motive-specific factors that indexed unique motivations for substance use: Emotional Coping (relief from unpleasant emotions), Pleasure-Seeking (feel pleasurable or exciting emotions and sensations), Dependence Severity (avoid withdrawal and cravings), Expansion (enhance self-insight and spirituality), Social Coping (increase confidence and attractiveness), Advantage (gain a physical or mental advantage), Physical Coping (relief from unpleasant bodily sensations), and Sleep (mitigate sleep problems). Evaluation of the measure's construct validity and internal consistency support the chosen model and interpretation of the motive-specific factors. Results provide initial validation of the MI-USE as a reliable and valid tool for assessing diverse substance use motivations. It improves upon existing measures by allowing clinicians and researchers to simultaneously evaluate motivations for multiple forms of substance use, which facilitates personalized treatment planning and research on polysubstance use.

The Pattern of Substance Use and Characteristics of the Individuals Enrolled in Residential Treatment at Selected Rehabilitation Centers in Sri Lanka: A Descriptive Cross-Sectional Study

Introduction:

Substance use becomes censorious when it leads to harmful effects on individuals, their families, and the community. The nature of substance use in Sri Lankan context is poorly understood and empirical evidences are sparse. The study aimed to describe patterns of substance use and characteristics of the individuals enrolled in residential treatment at selected rehabilitation centers in Sri Lanka.

Material and methods:

A descriptive cross-sectional study was conducted among 205 individuals enrolled in selected rehabilitation centers. Pretested interviewer-administered questionnaire was used to collect data. Data were analyzed using descriptive statistics.

Results:

Most of the individuals who enrolled in residential treatment at selected rehabilitation centers were unmarried (n = 124, 60.5%), Sinhala (n = 186, 90.7%), Buddhist (n = 166, 81.0%), males (n = 202, 98.5%) and belonged to the young adult age (18-35 years) category (n = 178, 86.8%). All the participants were poly-drug users and cannabis was the most commonly used (n = 183, 89.3%) illicit drug followed by heroin (n = 172, 83.9%), methamphetamine (n = 150, 73.2%) and cocaine (n = 78, 38%). The most (n = 152, 74.1%) problematic substance for life was heroin. Most of the participants (n = 149, 72.7%) had used drugs several times per day. The mean duration of substance use was 7 ± 5 years. Participants (n = 177, 86.3%) reported that the substances were available in their residential areas and their friends (n = 197, 96.1%) were also using the substances.

Conclusions:

Pattern of substance use and characteristics of the individuals were unique in Sri Lanka and need to be considered when implementing and strengthening the programs for drug prevention and rehabilitation.
