Leveraging crowdsourcing methods to collect qualitative data in addiction science: Narratives of non-medical prescription opioid, heroin, and fentanyl use

Conceptualizing problematic use of medicinal Cannabis: Development and preliminary validation of a brief screening questionnaire

The use of Medicinal Cannabis (MC) for treating chronic pain is increasing, globally, yet the definition of problematic MC use remains unclear. Defining problematic use of cannabis in medical and non-medical contexts may be fundamentally different since individuals prescribed MC often experience physical dependence, which do not necessarily imply pathology. We aimed to conceptualize problematic use of MC and develop a brief questionnaire for identifying and quantifying problematic MC use. Content validation used a broad definition of problematic substance use, adapting and compiling an initial list of 36 items from various sources: (a) screening tools for assessing problematic prescription opioid medication use; (b) screening tools for problematic recreational cannabis use and (c) qualitative interviews with MC patients. 390 American self-identified chronic pain patients holding a MC card rated each item from the initial list on a 5-point frequency scale and filled out questionnaires assessing various clinical outcomes. Following initial item titration, a multi-group measurement invariance comparison strategy, using two external indicators: alcohol-related problems and depression, resulted a final eight-item list that met fit quality in a baseline model, presented excellent internal consistency reliability (α = 0.929), and significantly correlated with anxiety and low quality of life. Items in the final list related predominantly to negative consequences of MC use. Problematic use of MC is characterized by negative physiological, social, emotional and functional consequences. The final eight-item list was named the Medicinal Cannabis Negative Consequences Scale (MCNCS), emerging as a brief measure for problematic MC use and demonstrating preliminary reliability and validity, which could aid clinicians and researchers.

Next-day responsibilities attenuate demand for alcohol among a crowdsourced sample of community adults

While several studies have examined how class time and internship responsibilities impact demand for alcohol in undergraduate samples, no study has examined this question using more universally applicable responsibilities with a sample of community adults. Therefore, the aim of this study was to examine the impact of a range of next-day responsibilities on demand for alcohol among a crowdsourced sample of community adults using a hypothetical alcohol purchase task (APT). Community adults (n = 261; 79% White; 60% identified as men; 39% identified as women; and 1% identified as nonbinary) with a mean age of 38.42 recruited from Amazon Mechanical Turk rank-ordered eight hypothetical next-day responsibilities across three categories (i.e., work, caregiving, and recreational). Participants first completed a standard APT with no explicit next-day responsibilities, followed by purchase tasks in the context of their two highest ranked responsibilities. All participants needed to pass several stages of attention and data quality checks to be included in the final sample. All observed demand indices (i.e., intensity, breakpoint, Omax, and Pmax) were significantly higher in the no responsibilities condition compared to both the first- and second-ranked responsibility condition (ps < .001); however, there was no significant difference in any demand index between the first- and second-ranked responsibility (p range .65-.91). These results extend prior work by demonstrating engagement with substance-free alternatives may reduce demand for alcohol among community adults.

A cross-sectional survey on cannabis: Characterizing motives, opinions, and subjective experiences associated with the use of various oral cannabis products

BACKGROUND

Cannabis-infused products available for oral consumption include food and drink items (i.e., edibles) (e.g., baked goods, gummy-, chocolate-, and hard-candies, beverages/drinks) as well as non-food formulations (e.g., oils/tinctures, pills/capsules). This study characterized the motives, opinions, and subjective experiences associated with the use of these seven subtypes of oral cannabis products.

METHODS

This web-based survey collected cross-sectional, self-report data from a convenience sample of 370 adults regarding various use-motives, self-reported cannabinoid content, subjective experiences, and opinions related to ingesting oral cannabis products with alcohol and/or food. Advice participants had received about modifying oral cannabis product effects, in general, was also collected.

RESULTS

Participants reported consuming cannabis baked goods and gummy candies most frequently over the past year (68% and 63%, respectively). Participants were less likely to use oils/tinctures for enjoyment/desire relative to other product types and more likely to use oils/tinctures for therapeutic purposes (e.g., medication-replacement). Self-reported cannabinoid content was highly variable across participants and within product subtype. Participants reported feeling stronger and longer-lasting effects when consuming oral cannabis products on an empty stomach and 43% received advice to "eat a snack or meal" to mitigate effects that are too strong, which contrasts with controlled studies. Finally, 43% of participants reported modifying their experiences with alcohol at least some of time.

CONCLUSIONS

These findings underscore the need to further evaluate use-motives as well as the interaction between dietary factors, cannabinoid pharmacokinetics, and subjective drug effects and the interactive effects of oral cannabis products and alcohol in a controlled laboratory setting.

Intranasal Use of Prescription Stimulants Among Adults Aged 18 to 30: Results From A Crowdsourcing Platform

OBJECTIVE

Few studies of prescription stimulant non-oral, non-medical use (NMU) (defined by use not as prescribed) have been conducted in adults beyond the college population. The purpose of this study was to characterize prescription stimulant non-oral use, specifically intranasal (IN) use (snorting) in young adults.

METHOD

Amazon's MTurk platform was used to recruit participants for an online survey. Data were collected from March to April 2020.

RESULTS

Thirty-two percent (n = 157) of survey respondents (N = 975), aged 18 to 30, reported IN prescription stimulant use (average of 32.1 episodes of lifetime IN use). Adderall was the most-reported prescription stimulant used intranasally (89.2%). Most IN users (82%; n = 68) reported spending no more than 5 minutes tampering with prescription stimulants. Intranasal users said they would take the medication orally if unable to tamper or manipulate medication for IN use.

CONCLUSION

These data help quantify a complex public health issue of ongoing IN use of prescription stimulants and suggest a potential role for manipulation-deterrent medications.

Effect of brief nicotine corrective messaging on nicotine beliefs in persons who use opioids

This pilot study tested the effect of a brief nicotine education messaging exposure on beliefs about nicotine, nicotine-replacement therapy (NRT), and e-cigarettes. Participants ages 18 and older were recruited via Amazon Mechanical Turk to complete a 20-min online survey in April/May 2020 to assess relationships between opioid use, smoking, and other behaviors. Participants with past-month extra-medical opioid use completed questions on background characteristics and literacy and then were randomized in a 2:1 ratio of two conditions: nicotine education (n = 362) or no message control (n = 181). Beliefs about nicotine, NRT, and e-cigarettes were asked of all participants; this occurred after message exposure for the nicotine education condition. Bivariate and multivariable analyses examined differences in beliefs by study condition. Brief nicotine messaging increased the probability of a correct response to "Nicotine is a cause of cancer" (false, 63% vs. 36%) and reduced the probability of a don't know response (9% vs. 17%) compared to the no message control condition. Nicotine education also reduced false beliefs about harms of long-term NRT use compared to cigarettes (p < .05). In adjusted models, participants in the nicotine education group had lower mean false beliefs about nicotine (p < .001) and to a lesser extent NRT (p = .053) compared with the control group; there was no difference in mean false beliefs about e-cigarettes (p = .547) between groups. A brief education intervention produced similar changes in nicotine beliefs in adults with past-month extra-medical opioid use as in a general adult sample. Findings support the potential for impact of nicotine public education messaging in vulnerable populations. (PsycInfo Database Record (c) 2022 APA, all rights reserved).

Quality of Life and Opioid Use Motives: Direct and Indirect Associations with Risky Opioid Use in a Community Sample of Adults

Purpose: The opioid epidemic in the United States has resulted in mass mortality and economic costs exceeding $1 trillion. Poor health-related quality of life is evident among individuals entering treatment for opioid use disorder (OUD). Yet, little research has examined the influence of quality of life on risky opioid use among non-treatment-seeking adults. To help inform OUD prevention efforts, this study examined the association among quality of life domains, opioid use motives, and risky opioid behaviors in a community sample of opioid users. Methods: Participants (N = 278) were adults who endorsed past month opioid use and were not currently in treatment for OUD. Participants responded to questions regarding their opioid use and misuse, opioid use motives, opioid use consequences, and quality of life. Results: The physical health domain of quality of life was associated with risky opioid use. Specifically, poorer physical health predicted risky opioid use and this relationship was partially explained by more social and pain motives to use opioids. Surprisingly, no other quality of life domains predicted risky opioid use. Conclusion: This study represents a meaningful first step in identifying optimal targets for OUD prevention efforts with community samples. Our findings suggest that physical health is an important quality of life indicator to prevent opioid-related harm and development of OUD.

Use patterns, beliefs, experiences, and behavioral economic demand of indica and sativa cannabis: A cross-sectional survey of cannabis users

Cannabis products available for retail purchase are often marketed based on purported plant species (e.g., "indica" or "sativa"). The cannabis industry frequently claims that indica versus sativa cannabis elicits unique effects and/or is useful for different therapeutic indications. Few studies have evaluated use patterns, beliefs, subjective experiences, and situations in which individuals use indica versus sativa. A convenience sample of cannabis users (n = 179) was surveyed via Amazon Mechanical Turk (mTurk). Participants were asked about their prior use of, subjective experiences with, and opinions on indica versus sativa cannabis and completed hypothetical purchasing tasks for both cannabis subtypes. Participants reported a greater preference to use indica in the evening and sativa in the morning and afternoon. Participants were more likely to perceive feeling "sleepy/tired" or "relaxed" after using indica and "alert," "energized," and "motivated" after using sativa. Respondents were more likely to endorse wanting to use indica if they were going to sleep soon but more likely to use sativa at a party. Hypothetical purchasing patterns (i.e., grams of cannabis purchased as a function of escalating price) did not differ between indica and sativa, suggesting that demand was similar. Taken together, cannabis users retrospectively report feeling different effects from indica and sativa; however, demand generally did not differ between cannabis subtypes, suggesting situational factors could influence whether someone uses indica or sativa. Placebo-controlled, blinded studies are needed to characterize the pharmacodynamics and chemical composition of indica and sativa cannabis and to determine whether user expectancies contribute to differences in perceived indica/sativa effects.

Perception of Resource Allocations to Address the Opioid Epidemic

OBJECTIVES

Despite billions of dollars spent on opioid policy initiatives, public knowledge of evidence-based policies to reduce opioid-related morbidity remain low. Consequences of this knowledge gap for support of initiatives remains understudied. Our objective was to evaluate how participants with and without lived experience allocate funding for initiatives to address the opioid epidemic. A secondary objective was to collect proof-of-concept data of an informational intervention designed to improve support for evidence-based policies.

METHODS

Participants (N = 284; 57.2% female) without lifetime nonmedical opioid use (n = 98) and those with lifetime use (past year [n = 81] or nonpast year [n = 105]) of nonmedical opioids were recruited. All participants reported how they would allocate funds to demand reduction, supply reduction, harm reduction, and treatment policies. Half of all participants were then randomized to a brief informational intervention designed to emphasize evidence-based harm reduction and treatment programs.

RESULTS

Funding allocations were highest for policies related to community services and treatment and lowest for those related to harm reduction. Participants with lived experience allocated less to supply reduction policies. Participants (12%) who reallocated funds after information exposure increased funding to supervised consumption sites, dz = 0.77, naloxone distribution, dz = 0.85, syringe exchange programs, dz = 0.63, and medications for opioid use disorder access, dz = 0.70.

CONCLUSIONS

This study illustrates how people with and without lived experience prioritize various policies to address the opioid epidemic and emphasize comparably low support for harm reduction policies. Proof-of-concept data suggest that brief informational interventions may increase funding support for harm reduction strategies, at least in a subset of people.

Comparing the feasibility of four web-based recruitment strategies to evaluate the treatment preferences of rural and urban adults who misuse non-prescribed opioids

This cross-sectional study examined the feasibility of using four different web-based strategies to recruit rural and urban adults who use opioids non-medically for a survey on opioid use disorder (OUD) treatment preferences, and compared the treatment preferences of rural versus urban participants. Preferences for medication for opioid use disorder (MOUD) formulation and OUD treatment models were assessed through an online survey. Recruitment advertisements were shown on Facebook, Google AdWords, Reddit, and Amazon Mechanical Turk (MTurk). Participants were categorized by zip code into urban versus rural residence using the Centers for Medicaid and Medicaid Health Resources and Services Administration definitions. OUD treatment preferences were compared using chi-square and t-tests. Among the 851 participants recruited, 815 provided zip codes and were classified as residing in rural (n = 200, 24.5%) or urban (n = 615, 75.4%) regions. A crowdsourcing service (MTurk) recruited the most rural participants, while posts on a social news website (Reddit) recruited the most urban participants (χ²₃ = 17.0, p < 0.01). While preferred MOUD formulation and OUD treatment model did not differ by rurality, rural participants were more likely to report a willingness to receive OUD treatment integrated with general medical care (χ²₁ = 18.9, p < 0.0001). This study demonstrated that web-based strategies are feasible for recruiting rural adults who misuse opioids. Results suggest OUD treatment preferences largely did not differ by rural residence, and highlight the importance of enhancing the availability and increasing education about MOUD formulations in rural regions.

Consuming illicit opioids during a drug overdose epidemic: Illicit fentanyls, drug discernment, and the radical transformation of the illicit opioid market

BACKGROUND

North America continues to face an opioid overdose epidemic, driven by persistent increases in illicit fentanyls and fluctuations in potency leading to uncertainty for consumers. This qualitative study was conducted to better understand how people who inject drugs (PWID) came to recognize fentanyl as a growing adulterant of heroin and the subsequent sensory discernment strategies they employed to continue injecting. Our main objective was to investigate how observations and knowledge are combined as homegrown techniques for detecting fentanyl and minimizing risk. Secondary objectives were to examine the impact of growing fentanyl adulteration on individual drug use behavior.

METHODS

Between April and May 2019, 28 PWID (18 men, 10 women; average age = 38.43 years, SD = 9.26) were purposely recruited from a needle services program in Greensboro, North Carolina. Study participants were interviewed in-person using a qualitative, semi-structured instrument. Interviews were analyzed with a general inductive approach using NVivo12.

RESULTS

Participants described methods for detecting fentanyl in illicit opioids. Sudden increases in the potency of the 'rush' and sharp decreases in the length of the 'high' were chief indicators along with changes in drug color and texture. Heavy sedation was associated with fentanyl use and histamine-releasing effects characterized as 'pins and needles' were ascribed to injecting fentanyl as a component of the rush. Fentanyl's short high helped explain higher injection frequency and heavy sedation was the leading reason for co-using fentanyl with cocaine/crack or methamphetamine.

CONCLUSION

PWID have the capacity to recognize changes to the illicit opioid supply. Study participants navigated unpredictable fluctuations in the illicit opioid market by employing homegrown discernment techniques, modifying drug use behavior, and co-using non-opioid drugs. Researchers and policymakers should involve PWID as subject matter experts to help modernize harm reduction for the fentanyl age with practical strategies to boost resiliency and save lives.

People's naïve belief about curiosity and interest: A qualitative study

The purpose of this study was to critically examine how people perceive the definitions, differences and similarities of interest and curiosity, and address the subjective boundaries between interest and curiosity. We used a qualitative research approach given the research questions and the goal to develop an in-depth understanding of people's meaning of interest and curiosity. We used data from a sample of 126 U.S. adults (48.5% male) recruited through Amazon's Mechanical Turk (Mage = 40.7, SDage = 11.7). Semi-structured questions were used and thematic analysis was applied. The results showed two themes relating to differences between curiosity and interest; active/stable feelings and certainty/uncertainty. Curiosity was defined as an active feeling (more specifically a first, fleeting feeling) and a child-like emotion that often involves a strong urge to think actively and differently, whereas interest was described as stable and sustainable feeling, which is characterized as involved engagement and personal preferences (e.g., hobbies). In addition, participants related curiosity to uncertainty, e.g., trying new things and risk-taking behaviour. Certainty, on the other hand, was deemed as an important component in the definition of interest, which helps individuals acquire deep knowledge. Both curiosity and interest were reported to be innate and positive feelings that support motivation and knowledge-seeking during the learning process.

"How will I get my next week's script?" Reactions of Reddit opioid forum users to changes in treatment access in the early months of the coronavirus pandemic

BACKGROUND

The COVID-19 pandemic poses significant challenges to people with opioid use disorder (OUD). As localities enforce lockdowns and pass emergency OUD treatment regulations, questions arise about how these changes will affect access and retention in care. In this study, we explore the influence of COVID-19 on access to, experiences with, and motivations for OUD treatment through a qualitative analysis of public discussion forums on Reddit.

METHODS

We collected data from Reddit, a free and international online platform dedicated to public discussions and user-generated content. We extracted 1000 of the most recent posts uploaded between March 5th and May 13th, 2020 from each of the two most popular opioid subreddits "r/Opiates" and "r/OpiatesRecovery" (total 2000). We reviewed posts for relevance to COVID-19 and opioid use and coded content using a hybrid inductive-deductive approach. Thematic analysis identified common themes related to study questions of interest.

RESULTS

Of 2000 posts reviewed, 300 (15%) discussed topics related to the intersection of opioid use and COVID-19. Five major themes related to OUD treatment were identified: Concern about closure of OUD treatment services; transition to telehealth and virtual care; methadone treatment requirements and increased exposure to COVID-19; reactions to changing regulations on medications for OUD; and influences of the pandemic on treatment motivation and progress.

CONCLUSION

In the face of unprecedented challenges due to COVID-19, reactions of Reddit opioid forum users ranged from increased distress in accessing and sustaining treatment, to encouragement surrounding new modes of treatment and opportunities to engage in care. New and less restrictive avenues for treatment were welcomed by many, but questions remain about how new norms and policy changes will be sustained beyond this pandemic and impact OUD treatment access and outcomes long-term.

Social Capital-Accrual, Escape-From-Self, and Time-Displacement Effects of Internet Use During the COVID-19 Stay-at-Home Period: Prospective, Quantitative Survey Study

BACKGROUND

COVID-19 has spread like wildfire across the globe, prompting many governments to impose unprecedented stay-at-home orders to limit its transmission. During an extended stay-at-home period, individuals may engage in more online leisure activities. Internet use is a double-edged sword that may have both desirable and undesirable effects on psychological well-being, and this study sought to disentangle adaptive from maladaptive internet use amidst this unusual health crisis.

OBJECTIVE

The objectives of this study were to assess the prevalence of probable depression during the COVID-19 stay-at-home period and to test three hypothesized risk reduction or risk elevation mechanisms, namely social capital-accrual, escape-from-self, and time-displacement effects.

METHODS

This study took place from March to May 2020 at the early stage of the pandemic. The study adopted a prospective design, with an online survey administered to 573 UK and 474 US adult residents at two assessment points 2 months apart.

RESULTS

The prevalence of moderate to severe depression was 36% (bootstrap bias-corrected and accelerated [BCa] 95% CI 33%-39%) at Time 1 (ie, initial time point) and 27% (bootstrap BCa 95% CI 25%-30%) at Time 2 (ie, follow-up time point). The results supported the social capital-accrual hypothesis by showing that the approach coping style was inversely associated with Time 2 depression through its positive associations with both social networking and perceived family support. The results also supported the escape-from-self hypothesis by revealing that the avoidant coping style was positively associated with Time 2 depression through its positive associations with both gaming and cyberbullying victimization, but the serial mediation model was no longer significant after Time 1 depression and some demographic risk factors had been controlled for. Finally, the results supported the time-displacement hypothesis by showing that gaming was positively associated with Time 2 depression through its inverse associations with social networking and perceived family support.

CONCLUSIONS

During the extended stay-at-home period in the early stages of the COVID-19 pandemic, the prevalence of probable depression during the 2-month study period was high among the UK and US residents. Individuals with distinct coping styles may engage in different types of online leisure activities and perceive varying levels of social support, which are associated with risks of probable depression.

State pain management clinic policies and county opioid prescribing: A fixed effects analysis

BACKGROUND

The U.S. has seen an unprecedented rise in opioid-related morbidity and mortality, and states have passed numerous laws in response. Researchers have not comprehensively established the effectiveness of pain management clinic regulations to reduce opioid prescribing using national data.

METHODS

We combine a policy dataset from the Prescription Drug Abuse Policy System with the Centers for Disease Control and Prevention county-level opioid prescribing data, as well as with numerous government datasets for county- and state- level covariates. We predict retail opioid prescriptions dispensed per 100 people using county fixed-effects models with a state-level cluster correction. Our key predictors of interest are the presence of any state-level pain management clinic law and eight specific subcomponents of the law.

RESULTS

Pain management clinic laws demonstrate consistent, negative effects on prescribing rates. Controlling for county characteristics, state spending, and the broader policy context, states with pain management clinic laws had, on average, 5.78 fewer opioid prescriptions per 100 people than states without such laws (p < .05). Five specific subcomponents demonstrate efficacy in reducing prescribing rates: certification requirements (B = -6.02, p < .05), medical directors (B = -6.14, p < .05), dispenser and dispensing amount restrictions (B = -8.60, p < .01; B = -15.51, p < .001), and explicit penalties for noncompliance (B = -6.02, p < .05). Three subcomponents had no effect: prescription quantity restrictions and requirements to register with or review prescription drug monitoring programs.

CONCLUSIONS

Implementation of pain management clinic laws reduced county-level opioid prescribing. States should review specific components to determine which forms of law are most efficacious.

A mixed-methods approach to understanding overdose risk-management strategies among a nationwide convenience sample

BACKGROUND

This mixed-methods study compared drug use histories between individuals who had a reported non-fatal overdose to individuals who did not and described the overdose risk-management strategies as they were experienced by a sample of people who use drugs (PWUD). Shifts from non-medical prescription opioid use (NMPOU) to the use of heroin and synthetic opioids have been implicated in national increases in overdose incidences in the United States. However, relatively limited data exists regarding the narrative experiences of the evolving overdose risk management strategies among a nationwide sample of PWUD.

METHODS

Data recruitment was conducted via Amazon's mTurk crowdsourcing technology and was collected through semi-structured interviews that occurred in 2019. Participants (N = 60) with a history of NMPOU with transition to heroin or fentanyl use were recruited.

RESULTS

Participants reporting a previous non-fatal overdose were more likely to report a history of injection drug use, a history of heroin injection, greater overdose risk knowledge, and current medication for opioid use disorder (MOUD) use. Qualitative analysis revealed that participants attempted to mitigate overdose risk in primarily three ways: 1) self-regulation; 2) harm reduction; and 3) passive approach. Self-regulatory measures included administering small or incremental dosing, being mindful of personal tolerance limits, and avoiding the initiation of injection drug use. Harm reduction measures used to protect from overdose included carrying Narcan and relying on trusted drug-suppliers as references to drug purity. A passive approach indicated that participants relied on "luck" or divine support systems where religiosity and faith were endorsed as factors that mitigated personal overdose risk.

CONCLUSION

Participants reported successful overdose mitigation via self-regulation, which may suggest that PWUDs were capable at managing their drug use amid the overdose crisis. The importance of the drug-supplier relationship was critical to many in reducing their overdose risk as formal harm reduction services (e.g., safe injection sites) remain inaccessible in the U.S. Implications for drug policy and harm reduction interventions are discussed.
