Response Inhibition in Youth Undergoing Intensive Treatment for Obsessive Compulsive Disorder.

Response Inhibition (RI) is the ability to suppress behaviors that are inappropriate for a given context. Obsessive-compulsive disorder (OCD) has been associated with impaired RI in adults as measured by the Stop Signal Task (SST). Conflicting results have been found in terms of the relationship between OCD severity and SST performance, and no studies to date have examined the relationship between SST and response to OCD treatment. Also relatively unknown is whether RI performance in OCD is associated with developmental or gender differences. This naturalistic study examined the relationship between SST performance, OCD severity, and OCD treatment response in a pediatric sample undergoing intensive treatment involving exposure and response prevention and medication management (n = 36). The SST and Children's Yale-Brown Obsessive Compulsive Scale (CYBOCS) were administered at admission and program discharge. OCD severity was not significantly related to stop signal reaction time (SSRT) in the whole sample and among subgroups divided by age and gender. Baseline SSRT and SSRT change did not predict CYBOCS change across treatment in the whole sample, but exploratory analyses indicated both were significant predictors among female adolescents. Results suggest there may be developmental gender differences in the relationship between RI and clinical improvement in pediatric OCD.

Core Motivations of Childhood Obsessive-Compulsive Disorder: The Role of Harm Avoidance and Incompleteness.

In an effort to improve patient conceptualization and targeted treatment, researchers have sought to accurately classify OCD subtypes. To date, the most common form of OCD classification has used the content of symptom topography as opposed to functional links between symptoms to categorize OCD. The aim of the current study was to explore the associations between these two forms of OCD classification. Participant topographical symptoms were self-reported using the Obsessive-Compulsive Inventory-Child Version (OCI-CV). Clinicians assessed whether participant symptoms were motivated by harm avoidance and/or incompleteness. Structural equation modeling was employed to explore the associations between harm avoidance and incompleteness and symptom dimensions in youth with OCD. Results showed that harm avoidance was significantly associated with doubting/checking, obsessing, and neutralizing symptoms, whereas incompleteness was associated with doubting/checking, ordering, and neutralizing symptoms. Findings are consistent with child and adult literature and highlight the importance of assessing the underlying function of OC behaviors.

Disgust propensity and sensitivity in childhood anxiety and obsessive-compulsive disorder: Two constructs differentially related to obsessional content.

The role of disgust in anxiety and related disorders has been extensively studied in adults, however its role in childhood psychopathology is in need of further investigation. The adult literature has suggested that two distinct sub-constructs within "disgust proneness" may differentially predict anxiety-related disorders. Namely, disgust propensity (DP) has been defined as the likelihood an individual will experience a disgust reaction, and disgust sensitivity (DS) as the degree to which an individual is distressed by their experience of disgust. The current study aimed to validate the Disgust Propensity and Sensitivity Scale-Revised (DPSS-R) in a sample of youth receiving intensive services for OCD and anxiety, examine the relationship between disgust sub-constructs and obsessional content in a sample of youth with OCD, and examine the relationship between disgust change and symptom severity at discharge. A confirmatory factor analysis supported a two-factor structure of the DPSS-R. DP was found to be uniquely predictive of contamination obsessions, and DS was found to be uniquely predictive of moral obsessions. Lastly, change in DP, but not DS, predicted overall change in OCD symptom severity. The present study provides a valid measure of DS and DP in youth with anxiety and related disorders, and suggests that subconstructs of disgust may serve as distinct risk factors for obsessional content in youth with OCD. Future research should examine the predictive validity of DP and DS longitudinally, as well as examine effective ways to more effectively target DP with exposure therapy.

Association of Electroconvulsive Therapy With Psychiatric Readmissions in US Hospitals.

Importance: Although electroconvulsive therapy (ECT) is considered the most efficacious treatment available for individuals with severe affective disorders, ECT's availability is limited and declining, suggesting that information about the population-level effects of ECT is needed. Objective: To examine whether inpatient treatment with ECT is associated with a reduction in 30-day psychiatric readmission risk in a large, multistate sample of inpatients with severe affective disorders. Design, Setting, and Participants: A quasi-experimental instrumental variables probit model of the association correlation of ECT administration with patient risk of 30-day readmission was estimated using observational, longitudinal data on hospital inpatient discharges from US general hospitals in 9 states. From a population-based sample of 490 252 psychiatric inpatients, a sample was drawn that consisted of 162 691 individuals with a principal diagnosis of major depressive disorder (MDD), bipolar disorder, or schizoaffective disorder. The key instrumental variable used in the analysis was ECT prevalence in the prior calendar year at the treating hospital. To examine whether ECT's association with readmissions was heterogeneous across population subgroups, analyses included interactions of ECT with age group, sex, race/ethnicity, and diagnosis group. The study was conducted from August 27, 2015, to March 7, 2017. Main Outcome and Measures: Readmission within 30 days of being discharged. Results: Overall, 2486 of the 162 691 inpatients (1.5%) underwent ECT during their index admission. Compared with other inpatients, those who received ECT were older (mean [SD], 56.8 [16.5] vs 45.9 [16.5] years; P < .001) and more likely to be female (65.0% vs 54.2%; P < .001) and white non-Hispanic (85.3% vs 62.1%; P < .001), have MDD diagnoses (63.8% vs 32.0%; P < .001) rather than bipolar disorder (29.0% vs 40.0%; P < .001) or schizoaffective disorder (7.1% vs 28.0%; P < .001), have a comorbid medical condition (31.3% vs 26.6%; P < .001), have private (39.4% vs 21.7%; P < .001) or Medicare (49.2% vs 39.4%; P < .001) insurance coverage, and be located in urban small hospitals (31.2% vs 22.3%; P < .001) or nonurban hospitals (9.0% vs 7.6%; P = .02). Administration of ECT was associated with a reduced 30-day readmission risk among psychiatric inpatients with severe affective disorders from an estimated 12.3% among individuals not administered ECT to 6.6% among individuals administered ECT (risk ratio [RR], 0.54; 95% CI, 0.28-0.81). Significantly larger associations with ECT on readmission risk were found for men compared with women (RR, 0.44; 95% CI, 0.20-0.69 vs 0.58; 95% CI, 0.30-0.88) and for individuals with bipolar disorder (RR, 0.42; 95% CI, 0.17-0.69) and schizoaffective disorder (RR, 0.44; 95% CI, 0.11-0.79) compared with those who had MDD (RR, 0.53; 95% CI, 0.26-0.81). Conclusions and Relevance: Electroconvulsive therapy may be associated with reduced short-term psychiatric inpatient readmissions among psychiatric inpatients with severe affective disorders. This potential population health effect may be overlooked in US hospitals' current decision making regarding the availability of ECT.

Availability of Youth Services in U.S. Mental Health Treatment Facilities.

Despite concern about access to mental health (MH) services for youth, little is known about the specialty treatment infrastructure serving this population. We used national data to examine which types of MH treatment facilities (hospital- and community-based) were most likely to offer youth services and which types of communities were most likely to have this infrastructure. Larger (p < 0.001) and privately owned (p < 0.001) facilities were more likely to offer youth services. Rural counties, counties in which a majority of residents were nonwhite, and/or counties with a higher percentage of uninsured residents were less likely to have a community-based MH treatment facility that served youth (p < 0.001).

Racial/ethnic differences in perceived reasons for mental health treatment in US adolescents with major depression.

OBJECTIVE: Racial/ethnic differences in the course of treatment for a major depressive episode (MDE) among adolescents may arise, in part, from variation in the perceived rationale for treatment. We examined racial/ethnic differences in the perceived reasons for receiving mental health (MH) treatment among adolescents with an MDE. METHOD: A total of 2,789 adolescent participants who experienced an MDE and received MH treatment in the past year were drawn from the 2005 to 2008 National Survey on Drug Use and Health. Adolescents reported the settings in which they received care and reasons for their most recent visit to each setting. Distributions of specific depressive symptoms were compared across racial/ethnic groups. Racial/ethnic differences in endorsing each of 11 possible reasons for receiving treatment were examined using weighted probit regressions adjusted for sociodemographic characteristics, health and mental health status, treatment setting, and survey year. RESULTS: Despite similar depressive symptom profiles, Hispanic adolescents were more likely than whites to endorse "breaking rules" or getting into physical fights as reasons for MH treatment. Black adolescents were more likely than white adolescents to endorse "problems at school" but less likely to endorse "felt very afraid or tense" or "eating problems" as reasons for treatment. Asian adolescents were more likely to endorse "problems with people other than friends or family" but less likely than whites to endorse "suicidal thoughts/attempt" and "felt depressed" as reasons for treatment. CONCLUSION: Racial/ethnic minority participants were more likely than white participants to endorse externalizing or interpersonal problems and less likely to endorse internalizing problems as reasons for MH treatment. Understanding racial/ethnic differences in the patient's perceived treatment rationale can offer opportunities to enhance outcomes for depression among diverse populations.

Injection drug use is associated with suicide attempts but not ideation or plans in a sample of adolescents with depressive symptoms.

OBJECTIVE: Based on the interpersonal theory of suicide, pain habituation that occurs with injection substance use may raise risk for a suicide attempt. The current study tested whether injection substance use, relative to painless routes of substance administration, was related to greater risk for suicide attempts. We also assessed whether this risk was specific to suicide attempts and not suicidal ideation or suicide plans. METHODS: Data on 2095 substance-using adolescents aged 12-17 who endorsed clinically significant depression symptoms and answered questions on suicidal thoughts and behavior were drawn from the 2004-2011 National Survey on Drug Use and Health, a nationally representative household survey. Logistic regression analyses were conducted to assess the associations between injection substance use and suicidal ideation, plans, and attempts. RESULTS: Injection substance use was associated with suicide attempts (OR = 3.02, 95% CI = 1.75-5.23) but not ideation or plans. These findings were not accounted for by sex, age, race/ethnicity, family income, abuse and dependence symptoms, and depression symptoms. Among ideators, injection substance use was associated with suicide attempts (OR = 2.92, 95% CI = 1.58-5.06), but not plans. Among suicide planners, injection substance use was associated with suicide attempts (OR = 5.16, 95% CI = 1.88-14.17). CONCLUSION: Consistent with the interpersonal theory of suicide, adolescent injection drug use was associated with specific risk for suicide attempts but not ideation or planning. Hence, consideration of the manner in which adolescents use substances is important in evaluating suicide risk in this population.

Racial-ethnic disparities in outpatient mental health visits to U.S. physicians, 1993-2008.

OBJECTIVE: The purpose of this study was to examine racial-ethnic differences in use of mental health treatment for a comprehensive range of specific disorders over time. METHODS: Data from the National Ambulatory Medical Care Survey and the National Hospital Ambulatory Medical Care Survey were used to examine adult outpatient mental health visits to U.S. physicians from 1993 to 2008 (N=754,497). Annual visit prevalence for three racial-ethnic groups was estimated as the number of visits divided by the group's U.S. population size. Visit prevalence ratios (VPRs) were calculated as the minority group's prevalence divided by the non-Hispanic white prevalence. Analyses were stratified by diagnosis, physician type, patient characteristics, and year. RESULTS: VPRs for any disorder were .60 (95% confidence interval [CI]=.52-.68) for non-Hispanic blacks and .58 (CI=.50-.67) for Hispanics. Non-Hispanic blacks were treated markedly less frequently than whites for obsessive-compulsive, generalized anxiety, attention-deficit hyperactivity, personality, panic, and nicotine use disorders but more frequently for psychotic disorders. Hispanics were treated far less frequently than whites for bipolar I, impulse control, autism spectrum, personality, obsessive-compulsive, and nicotine use disorders but more frequently for drug use disorders. Racial-ethnic differences in visits to psychiatrists were generally greater than for visits to nonpsychiatrists. Differences declined with increasing patient age and appear to have widened over time. CONCLUSIONS: Racial-ethnic differences in receipt of outpatient mental health treatment from U.S. physicians varied substantially by disorder, provider type, and patient age. Most differences were large and did not show improvement over time.

Use of mental health services in transition age youth with bipolar disorder.

OBJECTIVES: There is concern that treatment of serious mental illness in the United States declines precipitously following legal emancipation at age 18 years and transition from specialty youth clinical settings. We examined age transition effects on treatment utilization in a sample of youth with bipolar disorder. METHODS: Youth with bipolar disorder (N=413) 7-18 years of age were assessed approximately twice per year (mean interval 8.2 months) for at least 4 years. Annual use of any individual, group, and family therapy, psychopharmacology visits, and hospitalization at each year of age, and monthly use from ages 17 through 19 years, were examined. The effect of age transition to 18 years on monthly visit probability was tested in the subsample with observed transitions (n=204). Putative sociodemographic moderators and the influence of clinical course were assessed. RESULTS: Visit probabilities for the most common modalities-psychopharmacology, individual psychotherapy, and home-based care- generally fell from childhood to young adulthood. For example, the annual probability of at least one psychopharmacology visit was 97% at age 8, 75% at age 17, 60% at age 19, and 46% by age 22. Treatment probabilities fell in transitionage youth from age 17 through 19, but a specific transition effect at age 18 was not found. Declines did not vary based on sociodemographic characteristics and were not explained by changing severity of the bipolar illness or functioning. CONCLUSIONS: Mental health treatment declined with age in this sample of youth with bipolar disorder, but reductions were not concentrated during or after the transition to age 18 years. Declines were unrelated to symptom severity or impairment.

Access to and use of non-inpatient services in New York State among racial-ethnic groups.

OBJECTIVE Nationwide studies contrasting service use of racial-ethnic groups provide an overview of disparities, but because of variation in populations and service systems, local studies are required to identify specific targets for remedial action. The authors report on the use of non-inpatient services regulated in New York State (NYS) and report use by the state's larger cultural groups. METHODS Data from the NYS Patient Characteristics Survey were used to estimate annual treated prevalence and treatment intensity, defined as the average number of annual weeks in service for non-Hispanic blacks, Hispanics, Asians, and non-Hispanic whites. The latter rates were obtained for specific types of treatment use, by person's age and diagnosis, for the state and for population density-defined regions. Statistical methods contrasted rates of whites with other groups. RESULTS A total of 578,496 individuals in these racial-ethnic groups were served in 2,500 programs, and 51% of those served were nonwhite. Treated prevalence rates of whites were lower than those of blacks and Hispanics and were substantially higher than prevalence rates for Asians. Statewide treatment intensity rates of all racial-ethnic and age groups were comparable except for lower use among Asians >65. Key findings from granular analyses were lower treatment intensity rates for black youths with disruptive disorders, Hispanic adults with anxiety disorders, and Asians >65 with depression compared with white counterparts. In upstate metropolitan areas, black youths and Hispanic adults received services in fewer weeks than whites, and in the New York City metropolitan area, whites >65 had higher treatment intensity rates than contrast groups. CONCLUSIONS Findings suggest a need for assistance to black families in negotiating the multiple systems used by their children, clinical training focusing on cultural symptom presentation, screening of Asians in community settings, and mandated cultural competency assessments for all programs.

Irritability and elation in a large bipolar youth sample: relative symptom severity and clinical outcomes over 4 years.

OBJECTIVE: To assess whether relative severity of irritability symptoms versus elation symptoms in mania is stable and predicts subsequent illness course in youth with DSM-IV bipolar I or II disorder or operationally defined bipolar disorder not otherwise specified. METHOD: Investigators used the Kiddie Schedule for Affective Disorders and Schizophrenia for School-Age Children to assess the most severe lifetime manic episode in bipolar youth aged 7-17 years who were recruited from 2000 to 2006 as part of the Course and Outcomes of Bipolar Youth prospective cohort study (N = 361), conducted at university-affiliated mental health clinics. Subjects with at least 4 years of follow-up (N = 309) were categorized as irritable-only (n = 30), elated-only (n = 42), or both irritable and elated (n = 237) at baseline. Stability of this categorization over follow-up was the primary outcome. The course of mood symptoms and episodes, risk of suicide attempt, and functioning over follow-up were also compared between baseline groups. RESULTS: Most subjects experienced both irritability and elation during follow-up, and agreement between baseline and follow-up group assignment did not exceed that expected by chance (κ = 0.03; 95% CI, -0.06 to 0.12). Elated-only subjects were most likely to report the absence of both irritability and elation symptoms at every follow-up assessment (35.7%, versus 26.7% of irritable-only subjects and 16.9% of those with both irritability and elation; P = .01). Baseline groups experienced mania or hypomania for a similar proportion of the follow-up period, but irritable-only subjects experienced depression for a greater proportion of the follow-up period than did subjects who were both irritable and elated (53.9% versus 39.7%, respectively; P = .01). The groups did not otherwise differ by course of mood episode duration, polarity, bipolar diagnostic type, suicide attempt risk, or functional impairment. CONCLUSIONS: Most bipolar youth eventually experienced both irritability and elation irrespective of history. Irritable-only youth were at similar risk for mania but at greater risk for depression compared with elated-only youth and youth who had both irritability and elation symptoms.

Declining use of electroconvulsive therapy in United States general hospitals.

BACKGROUND: Falling duration of psychiatric inpatient stays over the past 2 decades and recent recommendations to tighten federal regulation of electroconvulsive therapy (ECT) devices have focused attention on trends in ECT use, but current national data have been unavailable. METHODS: We calculated the annual number of inpatient stays involving ECT and proportion of general hospitals conducting the procedure at least once in the calendar year with a national sample of discharges from 1993 to 2009. We estimated adjusted probabilities that inpatients with severe recurrent major depression (n = 465,646) were treated in a hospital that conducts ECT and, if so, received the procedure. RESULTS: The annual number of stays involving ECT fell from 12.6 to 7.2/100,000 adult US residents, driven by dramatic declines among elderly persons, whereas the percentage of hospitals conducting ECT decreased from 14.8% to 10.6%. The percentage of stays for severe recurrent major depression in hospitals that conducted ECT fell from 70.5% to 44.7%, whereas receipt of ECT where conducted declined from 12.9% to 10.5%. For depressed inpatients, the adjusted probability that the treating hospital conducts ECT fell 34%, whereas probability of receiving ECT was unchanged for patients treated in facilities that conducted the procedure. Adjusted declines were greatest for elderly persons. Throughout the period inpatients from poorer neighborhoods or who were publicly insured or uninsured were less likely to receive care from hospitals conducting ECT. CONCLUSIONS: Electroconvulsive therapy use for severely depressed inpatients has fallen markedly, driven exclusively by a decline in the probability that their hospital conducts ECT.

Manic symptoms in youth with bipolar disorder: factor analysis by age of symptom onset and current age.

BACKGROUND: Factor analysis has been used to identify potential clinical subtypes of mania in pediatric bipolar disorder. Results vary in the number of factors retained. The present study used a formal diagnostic instrument to examine how symptoms of mania in young people are expressed, depending on age of symptom onset and current age. METHODS: Trained clinicians completed the Schedule of Affective Disorders and Schizophrenia for School-Age Children (K-SADS) Mania Rating Scale (MRS) with parents of 163 children with child-onset of symptoms (before age 12), 94 adolescents with child-onset of symptoms, and 90 adolescents with adolescent-onset of symptoms (after age 12). Factor analysis of symptom ratings during the most severe lifetime manic episode was performed for each age group. RESULTS: Symptom factor structures were established for each age group. Two factors were evident for children with child-onset of symptoms ("activated/pleasure seeking" and "labile/disorganized"), one factor was present for adolescents with child-onset of symptoms ("activated/pleasure seeking/disorganized") and two factors were evident for adolescents with adolescent-onset of symptoms ("activated/pleasure seeking" and "disorganized/psychotic"). The factor structures for children with child-onset and adolescents with adolescent-onset of symptoms were highly similar, with the latter factor structure including psychotic symptoms. LIMITATIONS: Limitations include reliance on retrospective parent report and potential issues with generalizability. CONCLUSIONS: Findings suggest mania symptomatology is largely similar when examined by both age of onset and current age, with some notable differences. Specifically, psychotic symptoms begin emerging as a distinct factor in adolescents with adolescent-onset of symptoms.

Use and abuse of alcohol and illicit drugs in US adolescents: results of the National Comorbidity Survey-Adolescent Supplement.

CONTEXT: Comprehensive descriptions of substance use and abuse trajectories have been lacking in nationally representative samples of adolescents. OBJECTIVE: To examine the prevalence, age at onset, and sociodemographic correlates of alcohol and illicit drug use and abuse among US adolescents. DESIGN: Cross-sectional survey of adolescents using a modified version of the Composite International Diagnostic Interview. SETTING: Combined household and school adolescent samples. PARTICIPANTS: Nationally representative sample of 10,123 adolescents aged 13 to 18 years. MAIN OUTCOME MEASURES: Lifetime estimates of alcohol and illicit substance use and DSM-IV diagnoses of abuse, with or without dependence. RESULTS: By late adolescence, 78.2% of US adolescents had consumed alcohol, 47.1% had reached regular drinking levels defined by at least 12 drinks within a given year, and 15.1% met criteria for lifetime abuse. The opportunity to use illicit drugs was reported by 81.4% of the oldest adolescents, drug use by 42.5%, and drug abuse by 16.4%. The median age at onset was 14 years for alcohol abuse with or without dependence, 14 years for drug abuse with dependence, and 15 years for drug abuse without dependence. The associations observed by age, sex, and race/ethnicity often varied significantly by previous stage of use. CONCLUSIONS: Alcohol and drug use is common in US adolescents, and the findings of this study indicate that most cases of abuse have their initial onset in this important period of development. Prevention and treatment efforts would benefit from careful attention to the correlates and risk factors that are specific to the stage of substance use in adolescents.

Racial differences in the availability and use of electroconvulsive therapy for recurrent major depression.

BACKGROUND: Black Americans with depression were less likely to receive electroconvulsive therapy (ECT) than whites during the 1970s and 80s. This pattern was commonly attributed to treatment of blacks in lower quality hospitals where ECT was unavailable. We investigated whether a racial difference in receiving ECT persists, and, if so, whether it arises from lesser ECT availability or from lesser ECT use within hospitals conducting the procedure. METHODS: Black or white inpatient stays for recurrent major depression from 1993 to 2007 (N=419,686) were drawn from an annual sample of US community hospital discharges. The marginal disparity ratio estimated adjusted racial differences in the probabilities of (1) admission to a hospital capable of conducting ECT (availability), and (2) ECT utilization if treated where ECT is conducted (use). RESULTS: Across all hospitals, the probability of receiving ECT for depressed white inpatients (7.0%) greatly exceeded that for blacks (2.0%). Probability of ECT availability was slightly greater for whites than blacks (62.0% versus 57.8%), while probability of use was markedly greater (11.8% versus 3.9%). The white versus black marginal disparity ratio for ECT availability was 1.07 (95% confidence interval 1.06-1.07) and stable over the period, while the ratio for use fell from 3.2 (3.1-3.4) to 2.5 (2.4-2.7). LIMITATIONS: Depressed persons treated in outpatient settings or receive no care are excluded from analyses. CONCLUSIONS: Depressed black inpatients continue to be far less likely than whites to receive ECT. The difference arises almost entirely from lesser use of ECT within hospitals where it is available.

Self-Disclosure and Mental Health Service Use in Socially Anxious Adolescents.

Social anxiety disorder is highly prevalent in adolescence, persistent into adulthood, and associated with multiple impairments. Despite the development of efficacious treatments for socially anxious youth, few affected adolescents receive such treatment. This study examined service use in a sample of high school students (n = 1,574), as well as predictors of treatment delay and factors associated with adolescents' disclosure of social difficulties. Self-report measures of social anxiety and service utilization were administered by study staff to 10th- and 11th-grade classrooms across three public high schools. Consistent with the literature, results indicated low treatment utilization (14 %) and lengthy delays in treatment initiation. Symptom severity, impairment, and disclosing anxiety to school personnel were significant predictors of service utilization. Several demographic and illness-specific factors were associated with a higher likelihood of disclosing social discomfort. These findings underscore the important role of school personnel in identifying and referring youth with anxiety disorders. Implications are discussed for increasing access to services, including school-wide screenings and training of school personnel to recognize and provide intervention for anxious youth.
