Longitudinal associations between age 20 problematic substance use and opioid use disorder incidence at age 30 – findings from an urban cohort

This study used data from a longitudinal prevention study in an urban cohort to examine associations between nicotine dependence, alcohol, and cannabis use disorder and disorder criteria at age 20, with opioid use disorder (OUD) incidence or criteria onset by age 30. The study sample included 1408 participants (57.5% female, 72.5% African American) drawn from two cohorts of participants in a mid-Atlantic region of the U.S. as part of a series of randomized controlled trials of elementary school-based universal prevention interventions. Lifetime cannabis use disorder (CUD), alcohol use disorder (AUD; both DSM-IV), and current nicotine dependence (Fagerstrom Test for Nicotine Dependence, FTND) assessed at age 20 were used to predict (1) DSM-IV lifetime OUD at age 30, and (2) OUD criteria between ages 20 and 30 in multivariable logistic regression models. Covariates for all analyses included sociodemographics (sex, race, and free/reduced-priced lunch status), community disadvantage, and intervention status. Nicotine dependence (FTND≥3) at age 20 predicted age 30 DSM-IV lifetime OUD (aOR = 2.37; 95% CI 1.02,5.54). The number of CUD criteria (aOR = 1.30; 95% CI 1.09,1.57) and nicotine dependence severity scores (aOR = 1.22; 95% CI = 1.05,1.41) at age 20 predicted any OUD criteria between the ages of 20 and 30. Findings are consistent with previous research on opioid use behavior in young adulthood and suggest that nicotine dependence and CUD criteria among urban young people predict onset of OUD and OUD criteria in young adulthood.

Designing a Nurse-Led Program for Self-Management of Substance Addiction Consequences: A Modified e-Delphi Study.

Therapeutic interventions for people with problematic use of psychoactive substances can help tackle specific needs related to substance addiction consequences. This modified e-Delphi study aimed to establish consensus on a training program for self-management of substance addiction consequences. The study was conducted between February and April 2022, with an experts' sample of 28 participants in the first round and 24 in the second. A priori consensus criteria were defined for each round. The results revealed a very strong consensus was achieved on the structure of the program and on clinical areas, such as the problematic use of substances, general health knowledge, health-seeking behavior and adherence, self-knowledge and well-being, social role and personal dignity, and family process. Additionally, over 80% participant consensus was achieved on an extensive number of interventions categorized as psychoeducational, psychotherapeutic, socio therapeutic, brief interventions, social skills training, problem solving techniques, relaxation techniques, and counseling. These findings may be able to fulfill a gap concerning structured treatment approaches for people with problematic use of psychoactive substances. Supporting self-management of the consequences of substance addiction and its application can change nurses' interventions.

'Let Others Love You Back to Health': The Role of Performance-based Support Groups for People in Recovery.

Peer support groups have become widely utilized among those in recovery from problematic substance use. Yet, these peer-based programs vary and research examining their effectiveness has yielded mixed results. Relatively less is known about the impacts of arts-based peer recovery programs. Some research suggests that theatre may offer a powerful tool to address biopsychosocial changes among individuals in recovery. To explore the role of arts-based peer support programs, we draw on qualitative interviews with performers in two arts-based recovery programs. Our findings suggest that arts-based peer recovery programs may aid individuals in recovery in four main ways. Performing allowed participants to build relationships with others in recovery, channel experiences creatively while challenging stigma, foster confidence and recovery-identity formation, aiding participants in working through emotional impacts of prior substance use. These findings support emerging scholarship examining the role of performance in challenging stereotypes about substance use to aid those in recovery.

Sociocultural determinants of alcohol and cannabis use and misuse among Nunavimmiut

ObjectiveStemming from historical traumas and changes in the Inuit way of life, substance use and its intertwined problems are a major cause of concern for Nunavimmiut. This study’s objective is to investigate sociocultural determinants of substance use and misuse to inform culturally appropriate public health programs.MethodsThe 2017 Qanuilirpitaa? survey was conducted among a sample intended to be representative of Nunavimmiut aged 16 and over (total n = 1326). Sociocultural factors included cultural identity, land-based activities, involvement in community activities, social support, and family and community cohesion. The frequency of binge drinking (5 or more drinks on one occasion), cannabis use, and problematic substance use (CAGE and DAST-10) were documented. Data were analyzed using weighted multivariate logistic regressions. Inuit partners were involved from the planning of analyses to the co-interpretation of results.ResultsNearly a third of Nunavimmiut aged 16 and over reported binge drinking at least once a week (29.3%), and 68.6% of drinkers were at risk of potential drinking problems. Forty-five percent (45%) reported using cannabis at least once a week, and 30% of drug users were at risk of potential drug abuse problems. Volunteering and participation in community activities were associated with lower odds of cannabis use, as was frequently going on the land with weekly binge drinking, potential drinking problems, and weekly cannabis use. Social support and community cohesion were associated with higher odds of weekly binge drinking, as was cultural identity (centrality scale) with potential drinking problems.ConclusionKey determinants of substance use relevant to Inuit culture were identified. Results are in line with our Inuit partners’ experience in their communities and are coherent with current land-based interventions implemented in Nunavik. A thorough understanding of substance use contexts and related stressors should guide the content and implementation of substance use programs in Nunavik.

Emotion Regulation Strategy Choices Following Aversive Self-Awareness in People with Nonsuicidal Self-Injury or Indirect Self-Injury

Emotion regulation difficulties are implicated prominently in self-injury. Additionally, emotion regulation strategy selection is a core component of the emotion regulation process. Yet it is unclear how people who engage in different forms of self-injury attempt to regulate negative affect when multiple strategies are available to them. This laboratory-based study examined emotion regulation strategy choices in individuals who engage in non-suicidal self-injury (n=40), indirect forms of self-injury (disordered eating and problematic substance use; n=46), and controls (n=48). Following a self-relevant stressor (negative autobiographical memory recall), participants selected one of six strategies based on what they believed would most effectively alter their affect. Strategies spanned behavioral (physical pain, a snack, word activity) and non-behavioral (rumination, reappraisal, doing nothing) domains. Compared to controls, individuals who engage in NSSI and indirect self-injury were more likely to select behavioral strategies. In addition, people with NSSI and indirect self-injury were more likely than controls to choose physical pain and less likely to ruminate. Findings indicate that people with direct and indirect forms of self-injury alike are more likely to take action than engage in further thought when experiencing aversive self-awareness, even when cognitive strategies are made salient. Results illuminate intervention targets for these clinical populations.

Substance use disorder and alcohol consumption patterns among Dutch physicians: a nationwide register-based study

PurposeProblematic substance use and Substance Use Disorders (SUD) are common in all layers of the population. Several studies suggest higher prevalence rates of problematic substance use among physicians compared to the general population, which is harmful for themselves and potentially impairs quality of care. However, nationwide comparison with a highly educated reference group is lacking. Using nationwide register data, this study compared the prevalence of clinical SUD diagnoses and alcohol consumption patterns between physicians and a highly educated reference population.MethodsA retrospective study was performed using registry data from 2011 up to and including 2019, provided by Statistics Netherlands. From the data, a highly educated reference group was selected and those with an active medical doctor registration were identified as “physicians”. Clinical SUD diagnoses were identified by DSM-IV codes in mental healthcare registries. Benchmark analyses were performed, without statistical testing, to compare the prevalence of SUD diagnoses and alcohol consumption patterns between physicians and the reference population.ResultsClinical SUD diagnoses were found among 0.3% of the physicians and 0.5% of the reference population, with higher proportions of sedative use disorder among physician patients. Among drinkers, the prevalence rates of heavy and excessive drinking were respectively 4.0% and 4.3% for physicians and 7.7% and 6.4% for the reference population.ConclusionPrevalence rates of SUD diagnoses were fairly comparable between physicians and the highly educated reference population, but physicians displayed more favorable alcohol consumption patterns. The use of sedatives by physicians might deserve attention, given the relatively higher prevalence of sedative use disorder among physicians. Overall, we observed relatively low prevalence rates of SUD diagnoses and problematic alcohol use, which may reflect a treatment gap and social desirable answers.

Cognitive and functional outcomes at age 21 after prenatal cocaine/polydrug exposure and foster/adoptive care

ObjectivePrenatal cocaine exposure (PCE) has been linked to specific cognitive deficits and behavioral outcomes through early adolescence but there is little information on adult outcomes nor on the relationship of environmental interventions, such as foster/adoptive care, to outcomes. MethodsAt 21 years, data were available on 325 young adults, [163 PCE and 162 non-exposed (NCE)], primarily African-American, with low SES, who were followed from birth in a prospective longitudinal cohort study. Participants were administered the Wechsler Abbreviated Scale of Intelligence (WASI-II) and surveyed regarding high school completion, problematic substance use, and incarceration/probation history. In the PCE group, 32 remained in non-kinship foster/adoptive care (PCE/FA) from early in life (< 4 years) to 17 years. Group differences were examined through t-tests, MANOVA/ MANCOVA with post-hoc analyses, comparing outcomes and environmental correlates of young adults with PCE vs. NCE, as well as outcomes of PCE young adults in non-kinship foster/adoptive care (PCE/ FA) vs. PCE in birth/kinship care and NCE young adults. ResultsAt 21 years, young adults with PCE had lower mean Full Scale (83.7 ± 10.4 vs. 87.3 ± 12.5, p < .01) and Perceptual Reasoning IQs (87.3 ± 11.5 vs. 91.4 ± 13.9, (p < .02), lower high school completion rates (75% vs. 86%, p < .02), and were marginally more likely to have been on probation than NCE young adults, but did not differ in Verbal IQ, self-report of problematic substance use or incarceration. Young adults with PCE in F/A had similar lower IQ scores but had better verbal skills and high school graduation rates that did not differ from NCE young adults (80.6 vs 86.2%, p > .05). They had higher drug exposure at birth and more experiences of maltreatment (p's < 0.05) but their home environment quality was better and lead levels lower (p's < 0.05) than those of young adults with PCE in birth/kinship care. ConclusionsYoung adults with PCE had lower Perceptual Reasoning and Full-Scale IQ scores, independent of caregiving placement, compared to non-exposed young adults. Young adults with PCE placed in non-kinship foster/adoptive care had lower lead levels, more stimulating home environments, better vocabulary skills and were more likely to graduate from high school than those in birth/kinship care,but were not different in their self-report of problematic substance use, or experiences of incarceration or probation. Our data suggest that some cognitive deficits observed in young adults with PCE may be biologically based, but that some functional outcomes can be modified through environmental interventions. Our data also reflect the complexity of disentangling the effects of teratologic exposures on long term outcomes across a variety of domains and the need for studies of children in the foster care system.

Incorporation of peer support in a novel community-based mobile withdrawal management program

Despite the sweeping and deep-rooted impacts of problematic substance use throughout Canada, services remain under-resourced and overwhelmed. Innovative approaches are required if meaningful change is to occur. In this paper, we examine the incorporation of peer support into a novel, community-based outreach withdrawal program which engages with participants where they are situated. Peer support is an evidence-based intervention utilized in a wide range of health care arenas. It employs lived experience as a skillset to address health care needs to complement other components in the therapeutic journey. In the context of an outreach withdrawal service, peer support holds potential to deconstruct the power dynamic that acts as a barrier in conventional withdrawal programs. Peer support promotes the concept of interdisciplinary care, while actively dismantling stigma. More research is required to evaluate outcomes, client satisfaction, and cost-effectiveness with regards to peer support interventions in community-based outreach detoxification programming.

Attitudes towards participating in research involving digital pill systems to measure oral HIV pre-exposure chemoprophylaxis: a cross-sectional study among men who have sex with men with substance use in the USA

ObjectivesThis quantitative survey sought to understand, among men who have sex with men (MSM) with potentially problematic substance use, the attitudes towards participation in research involving digital pill systems (DPS)...

Pain Management and Substance Use Disorders: A Position Statement.

The American Society for Pain Management Nursing and the International Nurses Society on Addictions hold the position that persons with co-occurring pain and substance use disorder have the right to be treated with dignity and respect and receive evidence-based, high-quality assessment and management for both conditions using an integrated, holistic, multidimensional approach. Nonopioid and nonpharmacological approaches to pain management are recommended. Opioids should not be withheld from anyone if necessary to treat pain, and a team-based approach, including pain and addiction specialists, should be utilized when possible. Pain management should include interventions aimed at minimizing the risk for relapse or escalation of problematic substance use and actively involve the person and their support persons in the plan of care. Institutions should establish policies and procedures that support this position statement.

Association of sociodemographic, proximal, and distal clinical factors with current suicidal ideation: Findings from a nonclinical sample of young adults.

Accumulating evidence indicates that a variety of distal and proximal factors might impact a risk of suicide. However, the association between both groups of factors remains unknown. Therefore, in the present study, we aimed to investigate the interplay between distal and proximal correlates of the current suicidal ideation. A total of 3,000 individuals (aged 18-35years, 41.7% males), who had reported a negative history of psychiatric treatment, were enrolled through an online computer-assisted web interview. Self-reports were administered to measure: (a) distal factors: a history of childhood trauma (CT), reading disabilities (RDs), symptoms of attention-deficit/hyperactivity disorder (ADHD), lifetime history of non-suicidal self-injury (NSSI), lifetime problematic substance use as well as family history of schizophrenia and mood disorders; (b) proximal factors: depressive symptoms, psychotic-like experiences (PLEs), and insomnia; and (c) sociodemographic characteristics. Suicidal ideation was directly associated with unemployment, being single, higher level of RD, lifetime history of NSSI as well as higher severity of PLEs, depression, and insomnia. The association of distal factors with suicidal ideation was fully (a history of CT and symptoms of ADHD) or partially (a history of NSSI and RD) mediated by proximal factors (PLEs, depression, and insomnia). Main findings from this study posit the role of distal factors related to neurodevelopmental disorders, CT and NSSI in shaping suicide risk. Their effects might be partially or fully mediated by depression, PLEs, and insomnia.

THE EXPERIENCES OF SOCIAL WORKERS PROVIDING MENTAL HEALTH SERVICES AT A MENTAL HEALTH FACILITY IN TSHWANE, SOUTH AFRICA

South Africa presents a high prevalence of mental health problems, with one in six South Africans being diagnosed with anxiety, depression and substance-use problems (excluding more severe conditions such as bipolar disorder or schizophrenia). The incidence of mental health problems is ranked third after HIV and other infectious diseases in determining the disease burden. Social workers are key professionals in rendering interventions and services aimed at treating persons with mental health problems. In this qualitative study, ten purposively sampled social workers providing mental health services at a mental health facility in Tshwane, South Africa were interviewed. The thematic analysis generated seven themes, four of which are discussed. The findings reveal that social workers are adequately capacitated to provide mental health services and are one of the key mental health service providers. Recommendations for practice are provided. Keywords: experiences, mental health, mental health services, mental healtcare user, social worker

Age of gambling onset and resultant gambling behavior during young adulthood in the United States.

Previous research has examined how the age at which an individual first gambles (age of gambling onset) correlates with problematic behavior later in life, such as problematic alcohol or substance use; however, much less is known about how age of gambling onset, particularly as a child or as a young adult, might influence future gambling. We assessed how self-reported age of gambling onset may have shaped more recent gambling and propensity to take risks. We analyzed questionnaire data and neurocognitive assessment data collected from young adults in the United States (n = 579) and conducted ordinal logistic regression to model our study variables. Upon examining three distinct age categories (under 18, 18-20, 21, and over), we found that earlier age of gambling onset was significantly associated with betting a higher overall proportion during a neurocognitive task. CONCLUSIONSAND SCIENTIFIC SIGNIFICANCE: Gambling more points on a laboratory-based task was correlated to earlier age of gambling onset. There were no statistically significant associations between age of gambling onset and severity of recent pathological gambling, nor gambling expenditure in the past year, nor gambling frequency in the past week.Future longitudinal study should discern the causality of these findings in both directions and ascertain whether these findings can be extended to older and clinical populations. Future work should explore other variables, such as ethnicity and socioeconomic background, that may be relevant to understanding variations in age of gambling onset and its repercussions.

Reducing craving and lapse risk in alcohol and stimulants dependence using mobile app involving ecological momentary assessment and self-guided psychological interventions: Protocol for a randomized controlled trial.

The prevalence of alcohol consumption in Poland is estimated to be as high as 80% of the adult population. The use of stimulants is the second most common reason for seeking addiction treatment. However, treatment outcomes remain unsatisfactory, as 40-85% of individuals who complete various treatment programs relapse and fall back into addiction within 2 years following program completion. The 13-armed randomized controlled trial aimed to assess the effectiveness of a mobile app-based self-guided psychological intervention delivered via a smartphone app (Nałogometr) in reducing craving and lapse risk in problematic alcohol or stimulants use. Participant recruitment and data collection will be performed from June 2022 to September 2022. The 4-week mobile intervention program will include short-term and long-term intervention modules based mainly on mindfulness and cognitive-behavioral therapy. Intervention effectiveness assessment will include Ecological Momentary Assessment. That is, we will collect longitudinal data on a set of characteristics of day-to-day functioning. The primary outcomes will include a self-reported number of lapses and addiction craving level. In contrast, the secondary outcomes will be the severity of problematic substance use, anxiety and depression scores, and life satisfaction scores. This study will establish how mobile app-based self-guided psychological interventions can help reduce craving and lapse risk in alcohol and stimulant dependence. If successful, this randomized controlled trial (RCT) may provide an innovative, easily available, and cost-effective mHealth approach for craving and lapse risk in substance addictions.

Coping and Co-Occurrence of Gaming Disorder and Substance Use in Recovering Substance Users.

There are a wide range of negative effects associated with both substance use disorders and behavioural disorders and their co-occurrence. Understanding the way in which at-risk populations (e.g., substance-abstinent users) interact with potentially addictive behaviours (e.g., gaming) and substance use-while navigating life stressors through differing coping styles-can inform preventative strategies. Therefore, the present study investigated 64 clinical participants and 138 general population participants. Each cohort was required to complete a battery of psychometric scales exploring problematic behaviours, problematic substance use, co-occurrence, and coping styles. Additional exploratory direct comparisons of gamers in the clinical cohort and gamers in the general cohort were carried out. The study's findings suggest that gamers from different populations (i.e., general and clinical) share similar at-risk behaviours. These problematic behaviours were more pronounced among abstinent substance use gamers, and more specifically among poly-substance use gamers. The findings of the present study add to the literature and suggest that dysfunctional coping style and the co-occurrence of problematic behaviours may have an impact on the assessment and potential treatment of substance abstinent gamers. The findings offer support for an integrated treatment approach, wherein both substance use and the other problematic behaviours (e.g., gaming) are considered in tandem.

Supporting people affected by problematic alcohol, substance use and other behaviours under pandemic conditions: A pragmatic evaluation of how SMART recovery Australia responded to COVID-19

BackgroundThe COVID-19 pandemic prompted rapid, reflexive transition from face-to-face to online healthcare. For group-based addiction services, evidence for the impact on service delivery and participant experience is limited. MethodsA 12-month (plus 2-month follow-up) pragmatic evaluation of the upscaling of online mutual-help groups by SMART Recovery Australia (SRAU) was conducted using The Reach Effectiveness Adoption Implementation Maintenance (RE-AIM) framework. Data captured by SRAU between 1st July 2020 and 31st August 2021 included participant questionnaires, Zoom Data Analytics and administrative logs. ResultsReach: The number of online groups increased from just 6 pre-COVID-19 to 132. These groups were delivered on 2786 (M = 232.16, SD = 42.34 per month) occasions, to 41,752 (M = 3479.33, SD = 576.34) attendees. Effectiveness: Participants (n = 1052) reported finding the online group meetings highly engaging and a positive, recovery supportive experience. 91 % of people with experience of face-to-face group meetings rated their online experience as equivalent or better. Adoption: Eleven services (including SRAU) and five volunteers delivered group meetings for the entire 12-months. Implementation: SRAU surpassed their goal of establishing 100 groups. Maintenance: The average number of meetings delivered [t(11.14) = -1.45, p = 0.1737] and attendees [t(1.95) = -3.28, p = 0.1880] per month were maintained across a two-month follow-up period. ConclusionsSRAU scaled-up the delivery of online mutual-help groups in response to the COVID-19 pandemic. Findings support the accessibility, acceptability and sustainability of delivering SMART Recovery mutual-help groups online. Not only are these findings important in light of the global pandemic and public safety, but they demonstrate the potential for reaching and supporting difficult and under-served populations.

Exploring arts-based interventions for youth substance use prevention: a scoping review of literature

IntroductionThere is a rise in problematic substance use among Canadian youth, which is precipitating a public health crisis. Interventions are needed to empower youth to mitigate substance use risks. Active youth involvement in substance use prevention is urgently needed to increase uptake and ownership of the process and outcome of the intervention. Arts-based interventions are ideal participatory action approaches that can empower young people to be active agents in substance use prevention. These approaches can help promote health, reduce harm, and change behaviours. Scoping reviews are a vital tool that can help the research team identify relevant interventions that can be adapted to a community.MethodsThis scoping review explores various arts-based substance use prevention interventions for youth. The scoping review used the iterative stages of Arksey and O’Malley to search Portal ERIC, Ovid MEDLINE, C.I.N.A.H.L., E.M.B.A.S.E., Web of Science, and A.P.A. PsycInfo and grey literature from Canadian Centre on Substance Use and Addiction and websites suggested by the Canadian Agency for Drugs and Technologies in Health. Inclusion criteria are a) articles utilizing arts-based intervention on substance use prevention; b) studies with a clearly defined intervention; c) intervention targeting the youth (age 12–17) and d) publications written in English. Thematic analysis was used to identify the main themes from the included articles.Results and discussionThemes identified in a thematic synthesis of these studies included a) the intent of the intervention; b) intervention characteristics; and c) the perceived effectiveness of interventions. Art-based interventions increased knowledge and changed attitudes and practices on substance use among youth. Making the interventions aesthetically appealing and engaging, active youth involvement in the development of the intervention and developing youth-centred interventions which attended to the realities they faced were central to the success of these interventions.

An innovative behavioral health care curriculum: The integrated advanced practice addictions nursing subspecialty.

There is a significant shortage of behavioral health providers trained in caring for patients with problematic substance use, particularly within integrated care settings. An innovative addictions nursing subspecialty curriculum was designed by interdisciplinary faculty from psychiatric nursing, family nursing, counseling, and social work and informed by integrated care, addictions, and telehealth competencies. The subspecialty included prevention, treatment, and recovery approaches to care and encouraged enrollment of students from various health-related disciplines to enhance the students' experiences of integrated care for substance use treatment prior to completion of the program. Subspecialty courses increased the number of advanced practice nurses in the behavioral health care workforce with enhanced knowledge of integrated telehealth substance use treatment. Implementation of similar innovative curricula across health disciplines may significantly improve the care delivered to patients with problematic substance use in traditional medical settings.

PP04 Supporting The Social Integration Of Persons With Brain Injury Using Psychoactive Substances: A Health Technology And Intervention Assessment

IntroductionPeople with a traumatic brain injury and who present with an unsafe or problematic substance use of psychoactive substances (PAS) face specific challenges in social integration resulting from the negative impacts of substance use on the benefits of rehabilitation services and treatments.MethodsA systematic review of grey and scientific literature was conducted. The selection and coding of the included interventions (according to their characteristics), as well as descriptive analyses, resulted in findings which describe the interventions under study. Grades of evidence strength were attributed to the findings based on a range of factors including the methodological characteristics of the studies. Findings resulting from the systematic review were contextualized with information collected from administrative databases, clinical program documentation, and experiential data obtained from rehabilitation professionals. Recommendations were elaborated based on the aggregated data sources and informal deliberations by a committee involving researchers and clinicians.ResultsOut of 5014 selected references, 14 studies examining 13 interventions which targeted social integration of the management of PAS were included. Interventions with the strongest evidence base are user-centered (i.e., support individual choices and personal autonomy), individualized (i.e., considered individual needs and characteristics), and educational (i.e., support the acquisition of strategies and abilities). The evidence base was considered “emerging” for interventions which are systemic in nature (i.e., relate to familial, social, cultural, educational or professional environments), interdisciplinary (i.e., involve clinicians with distinct training, competences and expertise), and ecological (i.e., which involve interventions in the client’s living settings). While additional research is necessary to better support their efficacy, these interventions exhibited promising effects on various outcomes.ConclusionsThe analysis and synthesis of three streams of information resulted in five clinical practice recommendations relating to integration to school and productive activities, psychological adaptation, integration in living settings and independence, social life and sense of belonging, and finally, use of PAS. Recommendations should help support clinicians in rehabilitation settings.
