ABSTRACT

Sexual transmission risk occurs in the context of serodiscordant condomless anal intercourse (CAI) where the seropositive partner is virologically detectable (VL+) and/or seronegative partner is not on PrEP. We analyzed correlates of serodiscordant CAI among 688 VL+ young men who have sex with men (YMSM). In multivariable analyses, serodiscordant CAI was associated with a receiving a HIV diagnosis in the past 6 months, greater depressive symptoms, and cocaine use during the past 90 days. Although HIV+ YMSM currently experience disparities across the continuum of care, those new to care may need support adopting risk reduction strategies with their sexual partners.

ABSTRACT

Youth living with HIV (YLH) experience multiple disease-related stresses along with the same structural and developmental challenges faced by their uninfected peers; alcohol use among YLH represents a risk behavior by virtue of potential effects on youth health and increased likelihood of engaging in unprotected sex while drinking alcohol. Research aimed at better understanding the interplay of individual- and neighborhood-level influences on alcohol use for YLH is needed to inform interventions. This study examined whether socioeconomic disadvantage (SED) and social support influence, independently and through interaction, alcohol use in YLH. Data from the Adolescent Medicine Trials Network for HIV/AIDS Interventions (ATN) consisted of YLH across 538 neighborhoods in the United States who acquired HIV behaviorally. Neighborhood-specific data were compiled from the 2010 U.S. Census Bureau and matched with individual-level data from the ATN (N = 1,357) to examine effects that contribute to variation in frequency of alcohol use. Other drug use, being male, being non-Black, and older age were associated with greater alcohol use. Higher social support was negatively associated with alcohol use frequency. A cross-level interaction indicated that the association found between decreasing social support and increasing alcohol use frequency was weakened in areas with lower SED. Implications are discussed.

ABSTRACT

In the United States, little is known about interventions that rely on mobile phones and/or text messaging to improve engagement in HIV care for vulnerable populations. Domestic studies using these technologies as part of the National Institute on Drug Abuse "Seek, Test, Treat, Retain" research initiative were queried regarding intervention components, implementation issues, participant characteristics, and descriptive statistics of mobile phone service delivery. Across five studies with 1,135 predominantly male, minority participants, implementation challenges occurred in three categories: (1) service interruptions; (2) billing/overage issues, and; (3) the participant user experience. Response rules for automated text messages frequently frustrated participants. The inability to reload minutes/texting capacity remotely was a significant barrier to intervention delivery. No study encountered confidentiality breaches. Service interruption was common, even if studies provided mobile phones and plans. Future studies should attend to the type of mobile phone and service, the participant user experience, and human subjects concerns.

ABSTRACT

Large-scale, multisite data sets offer the potential for exploring the public health benefits of biomedical interventions. Data harmonization is an emerging strategy to increase the comparability of research data collected across independent studies, enabling research questions to be addressed beyond the capacity of any individual study. The National Institute on Drug Abuse recently implemented this novel strategy to prospectively collect and harmonize data across 22 independent research studies developing and empirically testing interventions to effectively deliver an HIV continuum of care to diverse drug-abusing populations. We describe this data collection and harmonization effort, collectively known as the Seek, Test, Treat, and Retain Data Collection and Harmonization Initiative, which can serve as a model applicable to other research endeavors.

ABSTRACT

This randomized behavioral trial examined whether youth living with HIV (YLH) receiving cell-phone support with study funded phone plans, demonstrated improved adherence and viral control during the 24 week intervention and 24 weeks post-intervention compared to controls. Monday through Friday phone calls confirmed medications were taken, provided problem-solving support, and referred to services to address adherence barriers. Of 37 participants (ages 15-24), 62 % were male and 70 % were African American. Self-reported adherence was significantly higher in the intervention group compared to the control at 24 and 48 weeks for the past month (P = 0.007) and log 10 HIV VL was significantly lower at both 24 weeks (2.82 versus 4.52 P = 0.002) and 48 weeks (3.23 versus 4.23 P = 0.043). Adherence and viral load showed medium to large effect sizes across the 48 week study. This is the first study to demonstrate sustained clinically significant reductions in HIV VL using youth friendly technology.

ABSTRACT

The relationship between adherence to antiretroviral therapy (ART) and virologic outcomes in HIV+ children, adolescents, and young adults has been notably understudied, with much of the extant research focused on specific sub-literatures, such as resource-limited regions, specific clinical outcomes and time frames. The authors sought to better characterize the relationship between adherence to ART and virologic functioning along various sample and methodological factors. The authors conducted a meta-analysis of thirty-seven studies and utilized a random effects model to generate weighted mean effect sizes. In addition, the authors conducted meta-ANOVAs to examine potential factors influencing the relationship between adherence and three categories of clinical outcomes, specifically Viral Load (VL) <100, VL < 400, and continuously measured VL. The analyses included 5,344 HIV+ children, adolescents, and young adults. The relationship between adherence behaviors and virologic outcomes varied across different methods of measurement and analysis. The relationship between adherence and continuously measured VL was significantly larger than for dichotomously-coded VL < 400 at Qb (20.69(1), p < .0005). Caregiver self-report indices elicited very small to small magnitude effects across both VL < 100 and VL < 400 outcomes and combined informant reporting (youth/adolescent and parent) produced significantly larger effects than caregiver report alone with adherence and VL < 400 outcomes at Qb (9.28(1), p < .005). More recently published trials reported smaller relationships between adherence and categorical clinical outcomes, such that year of publication significantly negatively correlated with VL < 100 (r = -.71(14), p < .005) and VL < 400 (r = -.43(26), p < .02). The data suggest that the magnitude of the relationship between ART adherence and virologic outcomes among heterogeneous samples of HIV+ children, adolescents and young adults varies across virologic outcomes and may be affected by moderating sample and methodological factors. Methodological and research recommendations for the interpretation of the current findings as well as for future HIV adherence related research are presented.

ABSTRACT

HIV-infected persons who use drugs (PWUDs) are particularly vulnerable for suboptimal combination antiretroviral therapy (cART) adherence. A systematic review of interventions to improve cART adherence and virologic outcomes among HIV-infected PWUDs was conducted. Among the 45 eligible studies, randomized controlled trials suggested directly administered antiretroviral therapy, medication-assisted therapy (MAT), contingency management, and multi-component, nurse-delivered interventions provided significant improved short-term adherence and virologic outcomes, but these effects were not sustained after intervention cessation. Cohort and prospective studies suggested short-term increased cART adherence with MAT. More conclusive data regarding the efficacy on cART adherence and HIV treatment outcomes using cognitive behavioral therapy, motivational interviewing, peer-driven interventions and the integration of MAT into HIV clinical care are warranted. Of great concern was the virtual lack of interventions with sustained post-intervention adherence and virologic benefits. Future research directions, including the development of interventions that promote long-term improvements in adherence and virologic outcomes, are discussed.

ABSTRACT

OBJECTIVES: In high-income countries, hazardous alcohol use is associated with reduced receipt of antiretroviral therapy (ART) and viral suppression among people living with HIV (PLHIV) who inject drugs. These associations are less understood in lower middle-income countries (LMIC) and upper middle-income countries. DESIGN: We examined associations between hazardous alcohol use, ART receipt, and viral suppression among PLHIV who reported current or former injection drug use. Participants were from nine studies in the United States (high-income country), India (LMIC), Russia (upper middle-income country), and Vietnam (LMIC). METHODS: Hazardous alcohol use was measured via Alcohol Use Disorders Identification Test. Outcomes were HIV viral suppression (viral load of <1000 RNA copies/ml) and self-reported ART receipt. Logistic regression assessed associations between hazardous alcohol use and both outcome variables, controlling for age and sex, among participants with current and former injection drug use. RESULTS: Among 2790 participants, 16% were women, mean age was 37.1 ±â€Š9.5 years. Mean Alcohol Use Disorders Identification Test scores were 4.6 ±â€Š8.1 (women) and 6.2 ±â€Š8.3 (men); 42% reported ART receipt; 40% had viral suppression. Hazardous alcohol use was significantly associated with reduced ART receipt in India (adjusted odds ratio = 0.59, 95% confidence interval: 0.45-0.77, P < 0.001); and lower rates of viral suppression in Vietnam (adjusted odds ratio = 0.51, 95% confidence interval: 0.31-0.82, P = 0.006). CONCLUSION: Associations between hazardous alcohol use, ART receipt, and viral suppression varied across settings and were strongest in LMICs. Addressing hazardous alcohol use holds promise for improving HIV continuum of care outcomes among PLHIV who inject drugs. Specific impact and intervention needs may differ by setting.

ABSTRACT

BACKGROUND: With increasing data archives comprised of studies with similar measurement, optimal methods for data harmonization and measurement scoring are a pressing need. We compare three methods for harmonizing and scoring the AUDIT as administered with minimal variation across 11 samples from eight study sites within the STTR (Seek-Test-Treat-Retain) Research Harmonization Initiative. Descriptive statistics and predictive validity results for cut-scores, sum scores, and Moderated Nonlinear Factor Analysis scores (MNLFA; a psychometric harmonization method) are presented. METHODS: Across the eight study sites, sample sizes ranged from 50 to 2405 and target populations varied based on sampling frame, location, and inclusion/exclusion criteria. The pooled sample included 4667 participants (82% male, 52% Black, 24% White, 13% Hispanic, and 8% Asian/ Pacific Islander; mean age of 38.9 years). Participants completed the AUDIT at baseline in all studies. RESULTS: After logical harmonization of items, we scored the AUDIT using three methods: published cut-scores, sum scores, and MNLFA. We found greater variation, fewer floor effects, and the ability to directly address missing data in MNLFA scores as compared to cut-scores and sum scores. MNLFA scores showed stronger associations with binge drinking and clearer study differences than did other scores. CONCLUSIONS: MNLFA scores are a promising tool for data harmonization and scoring in pooled data analysis. Model complexity with large multi-study applications, however, may require new statistical advances to fully realize the benefits of this approach.

ABSTRACT

The examination of predictors of non-adherence in transplantation populations offers the potential to identify high-risk individuals and concomitantly generate effective adherence-promoting interventions. The present paper aggregated quantitative estimates of various correlates of treatment adherence in studies of pediatric transplantation. Seventeen studies and three classes of predictors of non-adherence, including demographic, psychosocial, and treatment-related predictors, were included in the current analyses. The weighted means effect sizes for the demographic factors were in the small to medium range (female gender mean d = 0.35, 95% CI = 0.32-0.38, n = 8; mean age d = 0.55, 95% CI = 0.52-0.58, n = 7), suggesting that older youth and males tended to display more non-adherence behaviors than younger youth and females, respectively. Several psychosocial factors exhibited large to very large relationships with non-adherence, in particular comorbid psychiatric conditions (mean d = 1.04, 95% CI = 0.66-1.42, n = 3) and child self-responsibility for medication (mean d = 0.88, 95% CI = 0.53-1.23, n = 3). Finally, prior treatment/grafts (mean d = 0.17, 95% CI = -0.15-0.49, n = 3) and donor source (mean d = 0.33, 95% CI = -0.10-0.76, n = 4) exhibited small, non-significant relationships with non-adherence. Limitations of the study are discussed as are future directions for research.

ABSTRACT

BACKGROUND: Transgender persons are highly victimized, marginalized, disproportionately experience incarceration, and have alarmingly increased rates of HIV infection compared to cis-gender persons. Few studies have examined the HIV care continuum outcomes among transgender women (TW), particularly TW who are involved with the criminal justice (CJ) system. METHODS: To improve our understanding of HIV care continuum outcomes and risk behaviors among HIV-infected TW who are involved with the CJ system, we analyzed data from the National Institute on Drug Abuse-supported Seek, Test, Treat, Retain (STTR) Data Harmonization Initiative. Baseline data were pooled and analyzed from three U.S. STTR studies to examine HIV risk and care continuum indicators among CJ-involved HIV-infected TW compared to cisgender men (CM), matched on age (within 5 years) and study at a ratio of 1:5. RESULTS: Eighty-eight TW and 440 CM were included in the study. Among matched participants, TW were more likely to report crack and cocaine use compared to CM (40%,16% respectively, p<0.001); both TW and CM reported high rates of condomless sex (58%, 64%, respectively); TW were more likely than CM to have more than one sexual partner (OR = 2.9, 95% CI: 1.6, 5.2; p<0.001) and have engaged in exchange sex (OR = 3.9, 95% CI: 2.3, 6.6; p<0.001). There were no significant differences between TW and CM in the percentage currently taking ART (52%, 49%, respectively), the mean percent adherence to ART (77% for both groups), and the proportion who achieved viral suppression (61%, 58%, respectively). CONCLUSIONS: HIV-infected CJ-involved TW and CM had similar use of ART and viral suppression but TW were more likely than matched CM to engage in exchange sex, have multiple sexual partners, and use crack/cocaine. TW and CM had similarly high rates of condomless sex and use of other drugs. TW require tailored risk reduction interventions, however both CJ-involved TW and CM require focused attention to reduce HIV risk and improve HIV continuum of care outcomes.

ABSTRACT

BACKGROUND: The authors examined associations between structural characteristics and HIV disease management among a geographically diverse sample of behaviorally and perinatally HIV-infected adolescents and young adults in the United States. METHODS: The sample included 1891 adolescents and young adults living with HIV (27.8% perinatally infected; 72.2% behaviorally infected) who were linked to care through 20 Adolescent Medicine Trials Network for HIV/AIDS Interventions Units. All completed audio computer-assisted self-interview surveys. Chart abstraction or blood draw provided viral load data. Geographic-level variables were extracted from the United States Census Bureau (e.g., socioeconomic disadvantage, percent of Black and Latino households, percent rural) and Esri Crime (e.g., global crime index) databases as Zip Code Tabulation Areas. AIDSVu data (e.g., prevalence of HIV among youth) were extracted at the county-level. Using HLM v.7, the authors conducted means-as-outcomes random effects multi-level models to examine the association between structural-level and individual-level factors and (1) being on antiretroviral therapy (ART) currently; (2) being on ART for at least 6 months; (3) missed HIV care appointments (not having missed any vs. having missed one or more appointments) over the past 12 months; and (4) viral suppression (defined by the corresponding assay cutoff for the lower limit of viral load at each participating site which denoted nondetectability vs. detectability). RESULTS: Frequencies for the 4 primary outcomes were as follows: current ART use (n = 1120, 59.23%); ART use for ≥6 months (n = 861, 45.53%); at least one missed HIV care appointment (n = 936, 49.50); and viral suppression (n = 577, 30.51%). After adjusting for individual-level factors, youth living in more disadvantaged areas (defined by a composite score derived from 2010 Census indicators including percent poverty, percent receiving public assistance, percent of female, single-headed households, percent unemployment, and percent of people with less than a high school degree) were less likely to report current ART use (OR: 0.85, 95% CI: 0.72-1.00, p = .05). Among current ART users, living in more disadvantaged areas was associated with greater likelihood of having used ART for ≥6 months. Participants living in counties with greater HIV prevalence among 13-24 year olds were more likely to report current ART use (OR: 1.32, 95% CI: 1.05-1.65, p = .02), ≥6 months ART use (OR: 1.32, 95% CI: 1.05-1.65, p = .02), and to be virally suppressed (OR: 1.50, 95% CI: 1.20-1.87, p = .001); however, youth in these areas were also more likely to report missed medical appointments (OR: 1.32, 95% CI: 1.07-1.63, p = .008). CONCLUSIONS: The findings underscore the multi-level and structural factors associated with ART use, missed HIV care appointments, and viral suppression for adolescents and young adults in the United States. Consideration of these factors is strongly recommended in future intervention, clinical practice, and policy research that seek to understand the contextual influences on individuals' health behaviors.

ABSTRACT

IMPORTANCE: Human immunodeficiency virus (HIV) diagnoses continue to increase among young men who have sex with men (YMSM). Many YMSM living with HIV engage in sexual risk behaviors, and those who have a detectable viral load can transmit HIV to sex partners. Understanding factors that are related to sexual risk taking among virologically detectable (VL+) YMSM can inform prevention and treatment efforts. OBJECTIVES: To describe differences between virologically suppressed (VL-) and VL+ YMSM living with HIV and to identify correlates of condomless anal intercourse (CAI) and serodiscordant CAI among VL+ YMSM. DESIGN, SETTING, AND PARTICIPANTS: In this cross-sectional survey conducted from December 1, 2009, through June 30, 2012, we studied 991 HIV-infected YMSM 15 to 26 years of age at 20 adolescent HIV clinics in the United States. Data analysis was conducted December 1, 2013, through July 31, 2015. MAIN OUTCOMES AND MEASURES: Demographic, behavioral, and psychosocial assessments obtained using audio computer-assisted self-interviews. Viral load information was obtained via blood draw or medical record abstraction. RESULTS: Of the 991 participants, 688 (69.4%) were VL+ and 458 (46.2%) reported CAI, with 310 (31.3%) reporting serodiscordant CAI in the past 3 months. The VL+ YMSM were more likely than the VL- YMSM to report CAI (detectable, 266 [54.7%]; suppressed, 91 [44.4%]; P = .01) and serodiscordant CAI (detectable, 187 [34.9%]; suppressed, 57 [25.0%]; P < .01). Multivariable analyses indicated that among VL+ YMSM, those reporting problematic substance use were more likely to report CAI (adjusted odds ratio [AOR], 1.46; 95% CI, 1.02-2.10) and serodiscordant CAI (AOR, 1.45; 95% CI, 1.06-1.99). Black VL+ YMSM were less likely to report CAI (AOR, 0.63; 95% CI, 0.44-0.90) or serodiscordant CAI (AOR, 0.66; 95% CI, 0.46-0.94) compared with other VL+ YMSM. In addition, VL+ YMSM who disclosed their HIV status to sex partners were more likely to report CAI compared with nondisclosing YMSM (AOR, 1.35; 95% CI, 1.01-1.81). Transgender participants were less likely to report CAI than cisgender participants (AOR, 0.35; 95% CI, 0.14-0.85). Last, VL+ YMSM who reported currently being employed were less likely to report serodiscordant CAI than those who were unemployed (AOR, 0.74; 95% CI, 0.55-0.99). CONCLUSIONS AND RELEVANCE: Targeted multilevel interventions are needed to reduce HIV transmission risk behaviors among YMSM living with HIV, particularly among those who are VL+.

ABSTRACT

INTRODUCTION: In addition to individual characteristics, there may be a wide range of environmental or neighborhood stressors that contribute to elevated cannabis use in groups of youth living with HIV/AIDS (YLHIV); however, the effects of social disorganization on cannabis use in YLHIV to date have not been studied. METHODS: We examined the effects of individual-level and neighborhood-level factors by developing hierarchical generalized linear models estimating odds of current cannabis use (any use during the past 3 months) and daily cannabis use among a sample of YLHIV (N = 1921) currently receiving medical care. RESULTS: The final model for daily cannabis use in the past 3 months included significant positive effects associated with hostility (O.R. = 1.08, 95% C.I.: 1.05, 1.11), being older (O.R. = 1.12, 95% C.I.: 1.05, 1.20), being a bisexual male (O.R. = 1.72, 95% C.I.: 1.10, 2.70), and residing in a community with a murder rate in the highest quartile (O.R. = 1.91, 95% C.I.: 1.27, 2.87), second highest quartile (O.R. = 1.62, 95% C.I.: 1.06, 2.46), or third highest quartile (O.R. = 1.52, 95% C.I.: 1.01, 2.30). DISCUSSION: This paper advances our knowledge of the multilevel factors associated with elevated cannabis use among groups of YLHIV and furthers our understanding of social and structural determinants of health in this population. Future research into cannabis use among YLHIV should consider, not only cannabis use within the context of the adjustment of living with HIV/AIDS, but also the stressors that characterize the environments in which groups of YLHIV live.

ABSTRACT

A pilot randomized clinical trial of youth ages 15-24 nonadherent to antiretroviral therapy (ART) utilizing daily cell phone support was found to have significant improvement in self-reported adherence and HIV RNA. Understanding acceptability and feasibility is critical for future implementation in clinic settings. Exit interviews were obtained from participants and adherence facilitators (AF). Acceptability was assessed from content analysis of exit interviews. Feasibility was assessed via intervention retention and study retention rates. Thirty-seven eligible youth were enrolled with 19 assigned to the intervention. Seven (37%) discontinued the intervention either due to missing over 20% of calls for two consecutive months (N=5) or missing 10 consecutive calls (N=2). Sixteen participants completed exit interviews, 15 reported the call length was just right, 13 reported they would have liked to continue calls after the 24-week intervention, and all participants reported they would recommend the intervention to friends. Scheduling and making calls required less than 1 h per week per participant. Providing cell phone support to youth nonadherent to ART was acceptable and feasible. While the cost is low compared to the price of ART, healthcare systems will need to explore how to cover the cost of providing cell phones (incentive).

ABSTRACT

OBJECTIVE: To measure rates of antiretroviral therapy (ART) use and virologic suppression among perinatally HIV-infected youth (PIY) and behaviorally HIV-infected youth (BIY) linked to care in the United States and examine the effects of demographic, biomedical, and psychosocial factors on those rates. METHODS: Between 2009 and 2012, 649 PIY and 1547 BIY in 20 Adolescent Medicine Trials Network for HIV/AIDS Interventions sites completed cross-sectional surveys through audio computer-assisted self-interviews. Viral load data were collected from chart abstraction or blood draw. RESULTS: Overall 82.4% of PIY and 49.1% of BIY reported current ART use. Only 37.0% of PIY and 27.1% of BIY were virologically suppressed. Virologic suppression rates did not vary as a function of time since HIV diagnosis in either group. Consistent HIV care and no current substance abuse were significant correlates of ART use among PIY. These variables and non-African American race were some factors associated with virologic suppression for PIY [odds ratios (ORs) P < 0.05]. Among BIY, older age, heterosexuals, employment, and education were significantly related to ART use (ORs: P < 0.05); suppression was related to ART use ≥6 months, ≥90% ART adherence, and consistent HIV care (ORs: P < 0.05). Nearly 75% (n = 498) of nonsuppressed youth reported unprotected sex in the past 3 months. CONCLUSIONS: There are continued challenges with successfully treating youth even once diagnosed and linked to HIV care. Strategies targeting barriers to ART access, use, and virologic suppression are needed to optimize the impact of the "Treatment as Prevention" paradigm among PIY and BIY.

ABSTRACT

The diagnosis of bipolar spectrum disorders (BPSD) is difficult to evaluate in child and adolescent populations. The current study examines whether commonly used behavior checklists- the Child Behavior Checklist, Teacher Report Form, and the Youth Self-Report form-are clinically useful in making a differential diagnosis between BPSD and other disorders. This study is the first to investigate the validity of integrating pairs of informants using these instruments to differentiate individuals with BPSD from those with disruptive behavior disorders, major depressive disorder, and any child or adolescent not meeting criteria for BPSD. Parent report best predicted diagnostic status, yet diagnostic efficiency statistics associated with these checklists were relatively poor. Results indicate that the Child Behavior Checklist has limited utility when attempting to derive clinically meaningful information about the presentation of juvenile BPSD.

ABSTRACT

Past literature has largely ignored the population frequency of multivariate factor and subtest score discrepancies. Another limitation has been that statistical models imperfectly model the clinical assessment process, whereby significant discrepancies between both factors and subtests are included in predictions about an individual's academic achievement. The present study examined these issues using a nationally representative sample (N = 1,185) completing the Differential Ability Scales. Results indicate that approximately 80% of children in a nonreferred sample show at least one statistically significant ability discrepancy. In addition, the global estimate of cognitive ability was the most parsimonious predictor of academic achievement, whereas information about ability discrepancies did not significantly improve prediction. Findings suggest that when predicting academic achievement, there is little value in interpreting cognitive scores beyond the global ability estimate.

ABSTRACT

Little is understood about the factors that influence a woman's preference for a particular type of treatment after an assault. Furthermore, it remains unclear the extent to which providing detailed information such as the mechanism underlying a treatment or its side effects can affect a client's treatment preference for psychotherapy or pharmacotherapy. The current study of 324 women with varying degrees of trauma exposure and posttraumatic stress symptoms experimentally manipulated the content of treatment rationales for two common PTSD treatments: sertraline (SER) and prolonged exposure (PE). Specifically, both information regarding the hypothesized mechanism of the treatment and treatment side effects were manipulated. In general, personal reactions were more positive and credibility was stronger for psychotherapy than pharmacotherapy. This preference for the psychotherapy persisted regardless of specific information presented in the treatment rationale. For those reporting heightened hyperarousal and those of minority status, there was an increased likelihood of more positive reactions to sertraline. The results highlight assessment of treatment-related beliefs and preferences early on in the therapeutic process. Ultimately, understanding the factors that shape treatment preferences may contribute to the development of personalized treatment strategies that integrate preferences and attitudes about treatment as a way of bolstering adherence and outcome.

ABSTRACT

OBJECTIVES: The objectives of this study were to: (i) describe the phenomenology of youths diagnosed with subsyndromal bipolar disorders; (ii) describe the phenomenology of youngsters who are the children of bipolar parents, who are also experiencing subsyndromal symptoms of bipolar disorder (patients with 'cyclotaxia'); and (iii) explore which symptoms may be most useful in identifying youths with cyclotaxia. METHODS: Four hundred outpatients between the ages of 5 and 17 years received a diagnostic assessment and psychometric questionnaires pertaining to mood symptomatology and psychosocial functioning. Parental diagnostic information was also obtained. Children and adolescents were assigned to one of three diagnostic groups: a 'syndromal bipolar disorder (BP)' group (n = 118), a 'sub-syndromal bipolar (SUB-BP)' group (n = 75), or a 'non-bipolar (NON-BP)' group (n = 207). In addition, based on parental diagnoses, youths were assigned to either a high genetic risk group (n = 167) or a low genetic risk group (n = 233). RESULTS: Youths with subsyndromal bipolar disorders were found to have intermediate degrees of manic symptoms than youths with bipolar disorder and youths without a bipolar diagnosis. Offspring of parents having a bipolar disorder were more likely to show symptoms of hypomania and mania than youths without a bipolar parent. Youths at genetic risk for developing a bipolar disorder were not found to be at higher risk for having a diagnosis of attention-deficit hyperactivity disorder or a disruptive behavior disorder. Finally, results suggest that elevated mood with irritability and rapid mood fluctuations are the key distinguishing characteristics of 'cyclotaxia'. CONCLUSIONS: There exists a group of youngsters who are the offspring of a parent/parents with a bipolar disorder who do not suffer from BP 1 or BP 2, yet have elevated mood symptoms and psychosocial dysfunction. As a result of these observations, treatment studies are needed for youths with 'cyclotaxia'.
