Psychiatric comorbidity and substance use treatment outcomes of adolescents

Kristin L. Tomlinson; Sandra A. Brown; Ana M. Abrantes

Treatment outcomes of 126 adolescents (13-18 years old) with comorbid substance use disorders (SUDs) and Axis I psychiatric disorders (mood, anxiety, conduct, and attention-deficit/hyperactivity disorders) were compared to 81 SUD adolescents with no additional Axis I disorder. Participants completed structured interviews and symptom measures while participating in an adolescent treatment program and at 6 months following treatment. Results indicated that comorbid youth received more treatment during the outcome period; despite this, more comorbid SUD-Axis I disordered adolescents used substances following treatment than SUD-only youth, even after controlling for socioeconomic status and ethnicity. Among comorbid youth, internalizing disordered adolescents were less likely to use substances during the follow-up period, and externalizing disordered youth returned to substance use most rapidly after discharge from treatment.

Social anxiety, negative affectivity, and substance use among high school students.

Mark G. Myers; Gregory A. Aarons; Kristin L. Tomlinson; Murray B. Stein

The literature regarding the relationship between adolescent social anxiety and substance use is sparse, and available studies have produced discrepant results. Similarly, negative affectivity is a mood-dispositional dimension that is infrequently considered in studies of substance use. The authors used dispositional structural equation modeling to examine the concurrent relationships of social anxiety and negative affectivity with adolescent substance involvement among 724 students in 1 southern California high school. The final model indicated that increased substance use was associated with having lower grade-point average, being male, being White, having higher levels of negative affectivity, and having lower levels of social anxiety. The findings confirm that negative affectivity is positively related to adolescent substance use, whereas social anxiety appears to be protective against substance involvement.

Self-medication or social learning? A comparison of models to predict early adolescent drinking

Kristin L. Tomlinson; Sandra A. Brown

The current study examined the effects of social anxiety, depressive symptoms, and alcohol expectancies of social behavior change on alcohol involvement to determine whether the self-medication and/or social learning models predicted drinking behavior in a sample of over 400 eighth grade students. Middle school students completed confidential surveys that assessed current alcohol use and expectancies as well as negative affectivity including social anxiety and depressive symptoms. Consistent with the self-medication hypothesis, depressive symptoms predicted more frequent and heavier alcohol use as well as solitary drinking. The social learning model was supported by a negative association between social anxiety and quantity/frequency of drinking and less drinking at parties, and a positive association between alcohol expectancies and all drinking outcomes. Additionally, social anxiety moderated the association between expectancies and alcohol use. These findings suggest that self-medication and social learning processes may both play a role in predicting early adolescent alcohol use and the contexts in which youths drink.

Relapse in alcohol- and drug-disordered adolescents with comorbid psychopathology: changes in psychiatric symptoms.

Denis M. McCarthy; Kristin L. Tomlinson; Kristen G. Anderson; G. Alan Marlatt; Sandra A. Brown

This study examined reciprocal relationships between posttreatment substance use and psychiatric symptoms in adolescents with both a substance use disorder and an Axis I mental health disorder. Participants (13-18 years old) were recruited from inpatient treatment centers and interviewed during treatment and monthly for 6 months. Participants who relapsed (N=103; 48% female) reported the incidence and severity of psychiatric symptoms experienced before and after their 1st posttreatment substance use. The number of symptoms and depression symptoms experienced were related to use of stimulants and other drugs during relapse. There was evidence for both self-medication (symptom reduction) and rebound (symptom exacerbation) effects of substance use on symptom severity. These results demonstrate that, for adolescents with both substance use and mental health disorders, psychiatric symptoms are 1 factor influencing posttreatment substance use.

Psychiatric Comorbidity Among Inpatient Substance Abusing Adolescents

Ana M. Abrantes; Sandra A. Brown; Kristin L. Tomlinson

ABSTRACT We studied the association between type, severity and sequencing of psychopathology and these same dimensions of substance involvement among inpatient substance-abusing adolescents with comorbid psychiatric disorders. Adolescents (N = 140, 54% female; 15.9 years) meeting DSM-III-R criteria for a substance use disorder and at least one other Axis I psychiatric disorder were interviewed while inpatients in an adolescent psychiatric facility. Findings point to associations between externalizing disorders and a history of regular use of cigarettes, alcohol, and stimulants among comorbid adolescents. When sequencing of psychopathology was examined, different substance use patterns were observed. Severity of depressive disorders was associated with more substance withdrawal symptoms, externalizing symptomatology was related to more substance dependence symptoms, and ADHD severity was associated with more alcohol dependence symptoms. Findings may have important clinical implications such as the need to assess comorbidity early and to develop treatment plans based on type of comorbid psychiatric disorder.


Assessment | 2002

Reliability, stability, and factor structure of the Bulimia Test-Revised and Eating Disorder Inventory-2 scales in adolescence.

Denis M. McCarthy; Jean R. Simmons; Gregory T. Smith; Kristin L. Tomlinson; Kelly K. Hill

The Eating Disorder Inventory–2 (EDI-2) and Bulimia Test–Revised (BULIT-R) have demonstrated strong reliability and validity in college students and adults. Although used in adolescent samples, little is known about the psychometric properties of these measures for adolescents. The reliability, factor structure, and mean levels of five EDI-2 scales and the BULIT-R were evaluated over 3 years. Data were collected yearly from two samples of adolescent females, one recruited from three public middle schools (n = 239, mean baseline age = 12.8) and one from two public high schools (n = 119, mean baseline age = 15.9). Results provide strong evidence for the reliability and stability of these measures. Mean levels of both measures appeared remarkably consistent over the 3 years. These results provide evidence of good psychometric performance for these scales in adolescence. The lack of change in these measures raises questions about the developmental trajectory of these variables through adolescence.

Alcohol and Other Drug Use in Middle School: The Interplay of Gender, Peer Victimization, and Supportive Social Relationships

Stephanie V. Wormington; Kristen G. Anderson; Kristin L. Tomlinson; Sandra A. Brown

The current study examined the impact of supportive social relationships (i.e., teacher support, adult support, school relatedness) and peer victimization on middle school students’ substance use. Over 3,000 middle school students reported on alcohol, cigarette, and marijuana use, supportive social relationships, and instances in which they were the victim of aggressive behavior. Mixed-effects logit regression analyses revealed complementary patterns of results across types of substances. Students who perceived high levels of social support were less likely to report alcohol and drug use initiation, particularly at low levels of peer victimization. Gender moderated the negative effect of peer victimization, with highly victimized boys most likely to report alcohol, cigarette, and marijuana use. Results indicated a complex interplay of social influences and moderating variables in predicting early onset alcohol and other drug use, one that researchers should consider when studying adolescents’ decisions to use alcohol and other drugs.

Social Anxiety and Onset of Drinking in Early Adolescence

Kristin L. Tomlinson; Kevin Cummins; Sandra A. Brown

The present study examines several types of social anxiety that may be associated with the onset of alcohol use in middle school students, and whether the relationship differs by sex and grade. Students in the seventh and eighth grades (N = 2,621) completed the Social Anxiety Scale for Adolescents and a measure of lifetime drinking via schoolwide surveys. Distinct aspects of social anxiety were associated with higher and lower rates of onset of alcohol use. A high level of fear of negative evaluation was associated with drinking initiation in boys and girls, while girls who reported no social anxiety or distress in new situations were more likely than other groups to have started drinking by early adolescence. Youths with either very low or very high levels of generalized anxiety had higher rates of drinking than youths with scores in between. These findings suggest that the relationship between social anxiety and initiation of alcohol use is complex and varies by type of anxiety symptomatology.

Peer Victimization and Adolescent Adjustment: Does School Belonging Matter?

Stephanie V. Wormington; Kristen G. Anderson; Ashley Schneider; Kristin L. Tomlinson; Sandra A. Brown

Recent research highlights the role of peer victimization in students’ adjustment across a variety of domains (e.g., academic, social), but less often identifies potential mediating variables. In the current study, we tested for direct effects from peer victimization to adolescents’ academic behavior and alcohol use, as well as indirect effects through school belonging. Adolescents from two large samples (middle school: N = 2,808; high school: N = 6,821) self-reported on peer victimization, school belonging, academic outcomes (GPA, school truancy), and alcohol use (lifetime, past 30 days). Two-group structural equation models revealed (a) direct and indirect paths from peer victimization to academic functioning; (b) indirect, but not direct, effects through school belonging for lifetime drinking; and (c) direct and indirect effects from peer victimization to current drinking. Findings implicate school belonging as a mediator between peer victimization and important outcomes in adolescence.

Feasibility and Reliability of a Coding System to Capture In-Session Group Behavior in Adolescents

Benjamin O. Ladd; Kristin L. Tomlinson; Mark G. Myers; Kristen G. Anderson

Limited research has explored the role of in-session behavior during motivational enhancement (ME) in group formats. The current study presents initial feasibility of assessing behavior of high school students (N = 425) attending Project Options, a voluntary secondary drug and alcohol prevention program utilizing ME techniques. Building on previous research exploring client language supporting/opposing health behavior, student group behavior was coded live at the specific utterance and global level; group leader behavior was also coded globally. Interrater reliability of the coding system was assessed, and preliminary validity of the coding system was examined by exploring associations between characteristics of group members and in-session group behavior. Initial reliability estimates were excellent for the specific behavior codes. Reliability of the global codes was mixed, with raters demonstrating good reliability on support for unhealthy behavior, opposition to unhealthy behavior, and support for healthy behavior. Reliability of the group leader codes was fair to poor. Greater percent healthy talk was associated with a lower percentage of group members reporting lifetime alcohol use. The results of the current study suggest that some in-session behavior at the group level can be coded reliably via live observation and that in-session behavior at the group level is associated with alcohol use prior to attending the program. Future research is needed to explore the utility of in-session behavior in terms of predicting future behavior at the group and individual level.
