Abstract

Background: The U.S. Department of Health and Human Services highlighted pain relievers as the most abused substance after marijuana. Pain reliever misuse (PRM) promotes other substance use (SU) disorders, organ dysfunction, overdose, death, family conflicts, and harmful risk-taking behaviors. Investigating adolescent PRM is critical to combatting overdose-related deaths, however, current evidence remains insufficient. 

Materials and Methods: We employed the Health Belief Model and Social Learning Theory framework to investigate PRM-related proximal risk (substance use risk perceptions, deviance, alcohol use, and depression) and protective (religiosity, mental health service utilization, emotional support, and negative substance use attitudes) factors in a sample of adolescents (NSDUH 2019, n = 13,397, 51% males). Data on PRM, risk, and protective factors were collected using validated scales. Data analysis examined variable distribution, multicollinearity across key predictors, impact of PRM risk, and protective factors using adjusted binary logistic regression. 

Results: Our results showed that greater levels of substance use risk perceptions (p = 0.013), religiosity (p = 0.044), and negative substance use attitudes (p = 0.0065) were associated with lower likelihood of engaging in PRM. Deviant behaviors (p < .0001), alcohol use (p < .0001), experiencing ≥1 major depressive episode (MDE) (p = 0.038), female (p = 0.0017), and family income below $20,000 (p = 0.036) significantly associated with PRM. 

Conclusion: Our findings demonstrate that adolescents with greater risk perception and negative attitudes towards SU are less prone to PRM. Conversely, adolescents who engaged in deviant behaviors, alcohol, and experienced ≥1 MDE were more inclined to PRM. Targeting at-risk adolescents, risk perceptions, and attitudes in PRM prevention interventions may mitigate SU and future PRM.

Introduction

Public records from the U.S. Department of Health and Human Services have marked pain relievers as the most abused substance after marijuana [1]. While the use of pain relievers under the supervision of a physician is safe and medically useful, their misuse has been repeatedly associated with adverse outcomes such as opioid use disorder, organ dysfunction, overdose, and mortality [2-4]. The high accessibility and legitimacy of pain relievers as over-the-counter medication contributes to its higher potential for abuse and, subsequently, to an array of deleterious health effects [5]. More specifically, pain relievers such as those sold under the names of Darvocet, Percocet, Vicodin, and Codeine act as depressants to the central nervous system, which could cause respiratory depression and death if consumed improperly [3]. 

Apart from the harmful physiological consequences, pain reliever misuse (PRM) may also result in unfavorable social impairments. One study has linked PRM with conflicts in the family environment, other substance use disorders, engagement in criminal activity, and harmful risk-taking behaviors, amongst other adverse sequelae [3]. Examining PRM among adolescents is a particularly pressing public health issue, as the number of adolescent overdose-related deaths has doubled over the past decade [6]. Indeed, 2.3 percent of U.S. adolescents reported PRM in 2019. Adolescence is a developmental period characterized by identity formation, changes in peer and family dynamics, and role confusion [7]. All these factors may heighten the engagement in risk behaviors, including the potential risk of prescribed drug misuse, especially pain relievers, which may be more accessible to adolescents than illicit drugs [7]. Initiation into PRM at this age is of particular concern, given that early drug use places an individual at greater risk and severity of use later in life [8].

Prior research has suggested that proximal individual-level factors, such as the social or intrapersonal elements of one’s behaviors and attitudes, could play a risk or protective role in prescribed drug misuse [9, 10]. The Health Belief Model (HBM) and Social Learning Theory (SLT) are prominent frameworks that explain the interplay between social and individual factors and health outcomes. HBM suggests that an individual's health behavior is influenced by their perceptions of the severity of a health problem, their susceptibility to it, the benefits of taking a specific action to reduce the risk, and the barriers to taking that action [11]. HBM is used to explore how adolescents' perceptions of the severity of PRM and their susceptibility to its negative consequences influence their likelihood of engaging in PRM. SLT emphasizes the role of observational learning and social reinforcement in shaping behavior. Individuals learn by observing the behaviors of others and the consequences of those behaviors [12]. Several studies have concluded that HBM and SLT frameworks are appropriate for analyzing the risk and protective factors associated with PRM among adolescents. Their results indicate a correlation between individual traits and the likelihood of drug misuse, either increasing or decreasing the risk [13-17]. For example, the results of a study support the relevance of social learning theory in understanding nonmedical prescription drug use [15]. Key findings indicate that adolescents with favorable attitudes towards substance use, those whose peers use drugs, and those whose parents and peers have lenient attitudes towards substance use are more likely to engage in nonmedical prescription drug use [18]. Combining the HBM and SLT elements generates a comprehensive theoretical framework that considers both individual perceptions and social influences in understanding adolescent PRM. This integrated approach will provide a more nuanced perspective on the factors influencing PRM and help guide targeted prevention interventions for at-risk adolescents. The present study employs the HBM and SLT theoretical frameworks to examine the proximal individual-level risk and protective factors associated with PRM in a national sample of adolescents in the U.S. The focus on individual-level factors is based on the importance of understanding the influence of the most proximal factors associated with PRM when attempting to place them in the context of more distal factors at the interpersonal, community, and societal levels. 

Research has found strong evidence for individual-level risk factors associated with substance misuse in U.S. adolescents [19]. Demographic and socioeconomic factors (i.e., age, gender, ethnicity, sexual orientation, household income, and composition) have been found to serve as risk factors for substance misuse [19, 20]. For instance, Edlund et al. [19] reported that adolescent females were more likely to use opioids than adolescent males, a finding that contradicts previous findings indicating a higher PRM prevalence among males [21]. Past research has also revealed racial or ethnic differences in adolescent substance use, with studies indicating the highest lifetime and past-month substance use rates reported among Hispanic adolescents, with the lowest rates of use reported by Asians, compared to non-Hispanic Whites [22]. In relation to prescription opioid misuse, data from the 2020 National Survey of Drug Use and Health (NSDUH) has reported that Blacks and Hispanics had a modest increase in the prevalence of opioid misuse (3.7%) compared to the national average (3.4%), while Asians had the lowest prevalence (2.3%) [1].

Overall, the literature is inconclusive on which race/ethnicity has the highest PRM prevalence, as other studies have also observed White adolescents to be the leading users [23, 24]. Population density has also been identified as an influential factor, as a higher likelihood of prescribed opioid misuse has been reported for adolescents who live in rural or small urban areas [25]. Lower socioeconomic status has also been linked to an increased probability of adolescent substance use [26-28]. The composition of the household has also been investigated for substance use, and results have shown higher levels of problematic substance use in single-parent families compared to mother-father families [29]. Lastly, the educational status of adolescents may also play a role in the likelihood of prescription drug misuse, as research has documented the highest rates of substance use in those who are not in school or are poorly adjusted to school [30]. 

Various individual-level factors, including attitudes and perceptions related to substance use, have been linked to substance use behaviors.  For instance, greater perception of substance-use-related risk of harm has been associated with lower levels of substance-use behaviors [31]. Conversely, lower perceived substance-use-related risk has been associated as a significant risk factor for substance use in adolescents [32, 33]. Additionally, the presence or absence of negative attitudes toward SU has been found to predict actual substance use behaviors among adolescents, with increased negative attitudes toward substance use predicting a lower prevalence of substance use behaviors among adolescents [34]. 

There is a vast body of literature linking adverse mental health outcomes to increased substance use [35]. Specifically, major depression (MD) has been identified as one of the leading causes of disability, with prevalence rates steadily increasing throughout the past decade and reaching 15.8% of U.S. adolescents in 2019 [36]. The prevalence of depression amongst U.S. children and adolescents has risen to up to 4

Objective

The objective of the current study was to explore the individual-level risk and protective factors associated with PRM among adolescents in the U.S.

Materials and Methods

Data Source

Data for this study utilized public-use files of the 2019 NSDUH. This cross-sectional survey provides annual data on the level and patterns of drug, alcohol, and illegal substance use and abuse, and mental health issues in a national sample of adolescents and adults [1]. The NSDUH obtained a sample of non-institutionalized, community-dwelling civilians aged 12 and older in the United States and used a multistage area probability design with demographic stratification [1, 5]. An audio computer-assisted self-interviewing method was used to collect the data. Respondents could read or listen to the questions and answer them on an NSDUH laptop. A more personal approach was followed for questions on illicit drug use and other sensitive behaviors. The audio computer-assisted self-interviewing feature enabled the respondents to read or listen to a question (on headphones) and enter the response into the computer themselves [1]. The present secondary analysis of the 2019 NSDUH was reviewed and approved by a prominent South Florida public University’s Institutional Review Board Protocol Exemption #: IRB-21-0518.

Measures

Dependent variables: The dependent outcome was any self-reported lifetime pain reliever misuse. The NSDUH adopted the item from the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV) [56]. Pain reliever misuse was defined as the use of unprescribed prescription pain relievers for recreational purposes. Participants answered the following question: “Have you ever, even once, taken (names of prescription pain reliever) that was not prescribed for you or that you took only for the experience or feeling it caused?” Any use was recoded into a binary variable identifying a history of pain reliever misuse (0 = “Did not misuse” 1 = “Misused”).

Independent variables: The NSDUH provided measurements that encompassed variables related to the risk and protective factors from multiple scales, including the National Comorbidity Survey Replication Adolescent Supplement (NCS-A) [1, 57], The National Longitudinal Study of Adolescent Health (ADD Health) [1, 58], and DSM-IV [1, 56]. We identified nine risk and protective factors to test our hypothesis [3, 10, 20, 28, 32, 39, 42]. Table 1 provides a summary of all measured items.

Data Analysis 

All data analyses were conducted using SPSS Version 28 [59]. A descriptive analysis was conducted to examine the study variables' distribution. Multicollinearity was assessed across all key predictors and based on a cutoff above four for the variance inflation factors (VIFs) and below 0.25 for tolerance. No multicollinearity was evident across key predictor variables.  A binary logistic regression was conducted to examine the effect of individual-level risk and protective factors on PRM among adolescents in the US while controlling for the influence of demographic and socio-economic covariates. Unadjusted binary logistic regression models, including predictors of interest and covariates, were conducted to show the associations of each unique variable on PRM in the unadjusted models. The unadjusted model p-value was set to 0.05 to be selected for the adjusted model. We estimated adjusted odds ratios and 95% confidence intervals for the associations between risk and protective factors of interest on PRM while adjusting for significant covariates found in the unadjusted model. Survey methods and weighting were used for complex statistical analyses to account for the study design in NSDUH (i.e., stratification and primary sampling unit) [5]. To be considered statistically significant in the adjusted model, the p-value was set at p < 0>

Results

Table 2 summarizes the sample demographics and the descriptive statistics of the key study variables. The study sample consisted of n= 13,397 adolescents aged 12-17 years using the NSDUH definition of adolescents, with a relatively equal distribution of males (51%) and females (49%). More than half of the respondents were non-Hispanic whites (51%) and were living in a core-based statistical area (CBSA) with less than one million people (53%). Approximately 55% of participants reported a family income of more than $75,000, while most adolescents reported living in a two-parent household (69%). 

Concerning individual protective factors, most of the respondents indicated having emotional support (91%), never having a major depressive episode (76%), or ever using alcohol (73%). In addition, more than half of the adolescents reported a family income more than twice the poverty threshold (58%).  Moreover, negative attitudes towards substance use (= 2.62, SE = .006) were reported, and most participants did not endorse pain relievers misuse (96%).  Regarding risk factors, participants reported low levels of risk perceptions towards substance use (= 3.10, SE = .01) and relatively low rates of deviant behavior (= 1.53 SE = .004).  Lastly, adolescents in this national sample reported moderate levels of religiosity (= 2.49, SE = .011).

A binary logistic regression accounting for the study strata and weighting was conducted to examine the effect of individual-level risk and protective factors on PRM among adolescents in the US (n= 13,397) while controlling for the influence of demographic and socio-economic covariates. The results of the unadjusted and adjusted models are reported in Table 3. In the final adjusted model (n= 12,374), greater substance use risk perceptions (AOR=0.56, CI: [0.35,0.88], p < .05), higher levels of religiosity (AOR=0.85, CI: [0.73,0.99], p < .05), and more negative attitudes towards substance use (AOR=0.72, CI: [0.58,0.91], p < .01) were associated with lower a likelihood of engaging in PRM.  Adolescents who engaged in deviant behaviors were four times more likely to report PRM (AOR=4.44, CI: [3.24,6.09], p < .001). Adolescents reporting alcohol use were twice as likely to endorse PRM (AOR=2.38, CI: [1.78,3.19], p < .001). Adolescents that had experienced at least one major depressive episode were also 1.34 times more likely to report PRM (AOR=1.34, CI: [1.02,1.77], p < .05). Compared to males, females were more likely to report PRM (AOR=1.50, CI: [1.18,1.92], p < .01). Adolescents with an annual family income less than $20,000 were two times more likely to report PRM (AOR=2.28, CI: [1.06,4.93], p < .05) compared to those with an annual family income more than $75,000.

Discussion

The primary aim of the present study was to assess the relationship between individual-level risk and protective factors and the likelihood of PRM in adolescents in the U.S. Specifically, the present study utilized the HBM and SLT as a conceptual framework to explore the relationship between a series of individual-level factors (i.e., risk perceptions towards substance use, deviance, depression, alcohol consumption, mental health service utilization, poverty, emotional support, religiosity, and negative attitudes towards substance use) and PRM in adolescents.  Our findings revealed various individual-level risk and protective factors associated with PRM among adolescents in the U.S. 

Our findings revealed that adolescents with greater substance use risk perceptions were less likely to engage in PRM. These findings are in line with previous work that has suggested lower substance use risk perceptions act as a risk factor for substance use among adolescents [32, 33]. The current findings also indicated that greater negative attitudes toward substance use were associated with a decreased likelihood of PRM among adolescents. This finding is supported by previous research indicating that greater negative attitudes towards SU were associated with a lower prevalence of substance use in adolescents [60]. Based on the present findings, it could be concluded that adolescents who strongly disapproved of their peers’ smoking (cigarettes and marijuana) and drinking were less likely to misuse pain relievers. Therefore, our findings suggest that both higher risk perception and stronger negative attitudes towards SU may act as protective factors against adolescent PRM. As such, intervention efforts should focus on developing prevention programs that shape and monitor adolescents' attitudes and behaviors toward PRM. Risk perception and negative attitudes towards substances could also be used as indicators to identify adolescents with an implicit predisposition toward PRM. Such early adolescents as follow-up interventions could encompass targeted educational components focused on building protective attitudes against PRM among adolescents. 

Mental health problems in adolescents have also been recognized as critical risk factors for substance abuse in this population, as mental health and SU problems may frequently be dually diagnosed [61]. Major depressive episodes (MDE), which are prevalent in adolescents with a history of substance use, have been consistently associated with opioid abuse and dependence [39, 62]. In line with these findings, the current study found that lifetime MDE was associated with an increased likelihood of adolescent PRM. As a single MDE appears to be predictive of PRM, screening and early identification of depressive symptoms could aid timely interventions (i.e., school counselor consultations or professional therapeutic services) depending on the severity and causes of depression. Subsequently, this would diminish the likelihood of PRM and potentially unfavorable health or social outcomes. In accordance, future research should investigate other commonly observed psychological/psychiatric conditions in adolescents and their association with PRM. As mental health disorders frequently occur in clusters, the identification of different predictors (e.g., anxiety disorders, stress-related disorders) would better inform the development of screening tools to minimize, if not prevent, PRM in this population. 

Moreover, considering that low MHSU has been observed to contribute to increases in mental disorders’ prevalence among adolescents [37], the study examined whether professional mental health treatment by a therapist, a specialized clinic, or a school counselor was associated with PRM. Surprisingly, no relationship was found between MHSU and PRM in adolescents.  One potential reason for the unexpected finding could be the underutilization of mental health services by those in need. Adolescents with a high risk for pain reliever misuse may not be accessing mental health services due to stigma, lack of resources, or lack of awareness of available services [63]. Additionally, the type and quality of mental health services being offered may not be appropriate or effective for addressing pain reliever misuse [64].

Additionally, based on previous reports, we hypothesized that greater availability of emotional support would be associated with a lower likelihood of PRM [65]. However, no relationship between the two constructs was found in the present study. 

In line with previous studies, our findings also revealed that adolescents involved in deviant behaviors were more likely to engage in PRM [41, 42]. Our results suggest that deviant behaviors, including fighting, carrying a handgun, stealing, and attacking others, are critical risk factors for PRM. Along with the other risk factors, the expression of deviant behavior could also be implemented in potential risk-assessment screening tools for use at risk for PRM. 

Additionally, our findings indicated that adolescents reporting ever using alcohol were more likely to report PRM. A few existing studies have noted that the co-occurrence of alcohol and opioid use is quite common and contributes to substance-use-related morbidity and mortality [46]. The present study suggests that this is also the case with PRM use among adolescents. Empirical research has established an association between prescribed opioid misuse and the co-use of other substances, such as tobacco and marijuana, among adolescents [10]. Our findings highlight how substance co-use, particularly drinking, could be detrimental to future PRM in adolescents. More specifically, the use of alcohol at least once was related to an increased likelihood of engaging in PRM. Using this single finding to inform interventions and develop screenings would be challenging. As such, further research should aim at exploring the association between drinking patterns (i.e., binge drinking) and PRM, as a measure of single alcohol use does not provide sufficient information regarding individual drinking habits.

Previous literature suggests that stronger religious beliefs may serve as a protective factor against substance use [27, 28]; the results of this study also observed such a relationship within the adolescent sample. This implies that promoting religious beliefs may be a potential strategy for reducing substance use among adolescents.

Furthermore, we examined the relationship between socioeconomic status and PRM [26-28]. Specifically, socioeconomic status was assessed in terms of the U.S. Federal Poverty Threshold by delineating between high (> 2 times the poverty threshold) versus middle status (up to 2 times the poverty threshold) and high (> 2 times the poverty threshold) versus low status (living in poverty). Further longitudinal research is needed to examine this positive correlation between low-income adolescents and PRM.

In summary, PRM could also lead to unfavorable social outcomes, such as family conflicts, substance use disorders, engagement in illegal activities, and risk-taking behaviors, in addition to heightened health-related risks [3]. Considering the multitude of impairments that PRM could impose on an adolescent’s life, the importance of studies that directly examine the risk and protective factors associated with PRM occurrence is essential. 

The present cross-sectional study aimed to identify the individual-level protective and risk factors of PRM using publicly available data from the 2019 NSDUH. To the best of our knowledge, no previous studies have focused exclusively on the relationship between individual-level risk and protective factors and PRM among adolescents. Additionally, the present methods approach allowed for a large national sample highly representative of the U.S. adolescent population. It should be noted that the present study observed a slightly larger proportion of adolescents who engaged in PRM (3.8%) compared to previous reports of U.S. adolescent PRM in 2019 (2.3%). 

However, the findings from the study should be interpreted in light of its methodological biases. The respondents could have exhibited a response bias as data was obtained using a self-report method. Substance misuse, except for being a susceptible topic, is also considered illegal and could result in stigmatization from others, thus lending itself to social desirability [66]. The study also utilized a cross-sectional research design; thus, the causal or directional order of the associations found cannot be implied. Further investigation in this area should strive to implement longitudinal designs to identify predictors of PRM among adolescents and potential changes over time. Additionally, this study was a secondary data analysis, and as such, the instruments and variables were limited to what was available in the existing data set. For most constructs, one-item proxy measures could have led to over-simplification of complex and multi-dimensional constructs (e.g., depression, emotional support, religiosity).

Conclusions

The findings suggested the risk for PRM, and other substance use among adolescents are similar. Adolescents who perceive substance use to be of greater risk and hold more negative attitudes toward substance use are less likely to misuse pain relievers. Conversely, adolescents who engaged more in deviant behaviors, used alcohol, and had experienced at least one major depressive episode in their lifetime were more likely to have engaged in PRM.
