Comparing Reported Prescription Drug Misuse between Ecological Momentary Assessment versus Timeline Follow-Back among College Students.

ABSTRACT: Background: Accurate assessment of prescription drug misuse (PDM) is critical among young-adult college students, a particularly high-risk group for this substance behavior. No studies have compared assessments of college students' reports of PDM obtained from their reporting in daily life (via ecological momentary assessment; EMA) to their retrospective accounts of PDM over the same period (via timeline follow-back interview; TLFB), an approach that is commonly used in substance use research. Purpose/Objectives: To determine day-level agreement and person-level agreement in college student reports of PDM in EMA versus TLFB methods. Methods: Participants were 297 college freshmen and sophomores (69% female) recruited based on misuse behavior in the past three months. PDM behaviors were captured in daily life using EMA for 28 days and TLFB administered during an in-person lab visit. Agreement was assessed at the person level (any PDM during the 28 days) and day level (PDM on a given day) using Cohen's kappa and percent agreement. Results: PDM was reported more frequently using TLFB compared to EMA. Person-level agreement between the two methods was good (k = 0.62, 95% CI: 0.53, 0.70), whereas day-level agreement was fair (k = 0.23, 95% CI: 0.19, 0.28). Agreement in stimulant misuse reported across methods was more consistent compared to reports of other medication classes. Conclusions: Findings offer implications for the assessment of college student PDM data in substance use research.

Project description:BackgroundPrescription drug misuse is an escalating public health problem that is prevalent among college students. Various factors, such as sex, age, race, mental health conditions, and fraternity and sorority membership, increase the risk for prescription drug misuse. Peer influences may also pose significant risks for starting prescription drug misuse, because peers are the primary source of misused prescription drugs among college students.ObjectivesTo examine college students' beliefs about prescription drug misuse among their peers and to understand their beliefs about the available and potential intervention efforts to reduce prescription drug misuse.MethodWe conducted a cross-sectional survey of 312 college students aged 18 to 30 years who were enrolled in a large midwestern US university. The survey included questions about the responders' demographic characteristics, beliefs, and perceptions regarding prescription drug misuse among their peers and potential reduction programs for prescription drug misuse.ResultsThe respondents' mean age was 21 years, and most (65%) respondents were women. A majority (90%) of the respondents were enrolled in the university as full-time students. More than 60% of the respondents reported knowing someone with prescription drug misuse in the past 12 months. Fraternity or sorority members were more likely to report peer prescription drug misuse than nonmembers (83% vs 60%, respectively; P = .017). Stimulants were the most misused drug class, accounting for 75% of all reported peer prescription drug misuse. Approximately 60% of the misused prescription drugs were sourced from peers, which included friends, roommates, and classmates. A total of 73% of respondents said that prescription drug misuse was a problem among college students and 67% agreed that interventions were needed to reduce prescription drug misuse. The perceived need for interventions varied by peer prescription drug misuse. A total of 90% of students whose peers did not misuse prescription drugs said that interventions were needed, but only 67% of those with peer prescription drug misuse thought that interventions were needed.ConclusionOur findings indicate that peer prescription drug misuse is very common among college students, and the most misused drug class is stimulants. Survey respondents perceived that the current interventions used to address prescription drug misuse are not very effective or may not be targeting the right population. Peer prescription drug misuse influences college students' perceptions about the risks and harms of prescription drug misuse, as well as the need for interventions.

Project description:BackgroundValidated tools for assessing alcohol use among young people in low-income countries are needed to estimate prevalence and evaluate alcohol-reduction interventions. We validated Alcohol Use Disorders Identification Test (AUDIT) against Timeline Follow Back (TLFB), Diagnostic and Statistical Manual of Mental Disorders (DSM-5) and phosphatidylethanol (PEth); and the 30-day-AUDIT against the 12-months-AUDIT among young Ugandans.MethodsIn 2018, we collected retrospective data on 30-day and 12-month AUDIT, TLFB and DSM-5 in a cross-sectional study of 15-24?year old residents of Ugandan fishing communities. AUDIT was administered by Audio Computer Assisted Self-Interviewing (ACASI) and DSM-5 and TLFB by psychiatric nurses. We determined PEth16:0/18:1 levels from dried blood spots using liquid chromatography tandem-mass spectrometry (heavy usage, ?210?ng/mL) and calculated sensitivity and specificity of AUDIT against the other measures.ResultsAmong 1281 participants (52.7% male, mean age 20?years), half (n?=?659; 51.4%) reported ever drinking alcohol, 19.4% had 12-month-AUDIT???8 (21.5% men; 17.0% women), and 24.2% had 30-day-AUDIT???8 (29.0% men; 18.9% women). Twenty percent of participants had detectable PEth with 55 (4.3%) classified as heavy drinkers; 50.7% reported???2 symptoms on DSM-5 and 6.3% reported binge drinking in the previous month based on TLFB (8.9% men, 3.5% women). The 30-day-AUDIT???8 had sensitivity 86.7%, 95%CI: 81.8%-90.7% and specificity 90.9%, 95%CI:89.0%-92.6% versus 12-month-AUDIT???8. Both 30-day and 12-month-AUDIT???8 were sensitive and specific markers of heavy drinking by PEth (12-month-AUDIT sensitivity?=?80.0%; 95%CI:67.0%-89.6%; specificity?=?83.3%; 95%CI:81.1%-85.3%). The 30-day-AUDIT was a sensitive and specific marker of binge drinking based on TLFB (sensitivity?=?82.7%; 95%CI:72.7%-90.2%, specificity?=?79.8%; 95%CI:77.4%-82.1%); 12-month-AUDIT had lower sensitivity. Both 30-day and 12-month AUDIT???8 were highly specific but insensitive markers of having DSM-5???2 symptoms.ConclusionAmong young people in Uganda, ACASI-administered 30-day and 12-month-AUDIT have good diagnostic properties compared to PEth, DSM-5 and TLFB. Self-reported AUDIT provides a quick and valid means of assessing alcohol misuse in these communities.

Project description:BACKGROUND:Across college campuses, the prevalence of clinically relevant depression or anxiety is affecting more than 27% of the college population at some point between entry to college and graduation. Stress and self-esteem have both been hypothesized to contribute to depression and anxiety levels. Although contemporaneous relationships between these variables have been well-defined, the causal relationship between these mental health factors is not well understood, as frequent sampling can be invasive, and many of the current causal techniques are not well suited to investigate correlated variables. OBJECTIVE:This study aims to characterize the causal and contemporaneous networks between these critical mental health factors in a cohort of first-year college students and then determine if observed results replicate in a second, distinct cohort. METHODS:Ecological momentary assessments of depression, anxiety, stress, and self-esteem were obtained weekly from two cohorts of first-year college students for 40 weeks (1 academic year). We used the Peter and Clark Momentary Conditional Independence algorithm to identify the contemporaneous (t) and causal (t-1) network structures between these mental health metrics. RESULTS:All reported results are significant at P<.001 unless otherwise stated. Depression was causally influenced by self-esteem (t-1 rp, cohort 1 [C1]=-0.082, cohort 2 [C2]=-0.095) and itself (t-1 rp, C1=0.388, C2=0.382) in both cohorts. Anxiety was causally influenced by stress (t-1 rp, C1=0.095, C2=0.104), self-esteem (t-1 rp, C1=-0.067, C2=-0.064, P=.002), and itself (t-1 rp, of C1=0.293, C2=0.339) in both cohorts. A causal link between anxiety and depression was observed in the first cohort (t-1 rp, C1=0.109) and only observed in the second cohort with a more liberal threshold (t-1 rp, C2=0.044, P=.03). Self-esteem was only causally influenced by itself (t-1 rp, C1=0.389, C2=0.393). Stress was only causally influenced by itself (t-1 rp, C1=0.248, C2=0.273). Anxiety had positive contemporaneous links to depression (t rp, C1=0.462, C2=0.444) and stress (t rp, C1=0.354, C2=0.358). Self-esteem had negative contemporaneous links to each of the other three mental health metrics, with the strongest negative relationship being stress (t rp, C1=-0.334, C2=-0.340), followed by depression (t rp, C1=-0.302, C2=-0.274) and anxiety (t rp, C1=-0.256, C2=-0.208). Depression had positive contemporaneous links to anxiety (previously mentioned) and stress (t rp, C1=0.250, C2=0.231). CONCLUSIONS:This paper is an initial attempt to describe the contemporaneous and causal relationships among these four mental health metrics in college students. We replicated previous research identifying concurrent relationships between these variables and extended them by identifying causal links among these metrics. These results provide support for the vulnerability model of depression and anxiety. Understanding how causal factors impact the evolution of these mental states over time may provide key information for targeted treatment or, perhaps more importantly, preventative interventions for individuals at risk for depression and anxiety.
