Enhancing Hispanic participation in mental health clinical research: development of a Spanish-speaking depression research site

Barriers to Healthcare for Latinx Autistic Children and Adolescents

PURPOSE

To understand the ways in which autistic Latinx children experience disparities in diagnosis, healthcare, and receipt of specialty services.

METHODS

417 individuals who identified as Latinx caregivers of autistic children who were members of the same integrated healthcare system in Northern California were surveyed. Responses were analyzed using the child's insurance coverage (Government or Commercial) and caregiver's primary language (Spanish or English).

RESULTS

Compared to the commercially-insured, government-insured participants accessed several services at a higher rate and were less likely to cite the high cost of co-pays as a barrier.

CONCLUSION

There were no significant differences in service access by language status, but Spanish speakers were more likely to cite health literacy as a barrier to receiving care.

¿Donde están? Hispanic/Latine inclusion, diversity and representation in the HEALthy Brain and Child Development Study (HBCD)

The HEALthy Brain and Child Development (HBCD) Study, a multi-site prospective longitudinal cohort study, will examine human brain, cognitive, behavioral, social, and emotional development beginning prenatally and planned through early childhood. Central to its mission of reducing health disparities is the establishment of the Spanish Language and Culture Committee (SLCC) within the HBCD framework, a significant step towards demographic representation and inclusivity in research. By addressing linguistic and sociocultural barriers and embracing the diverse identities of Hispanic/Latine individuals nationwide, the SLCC aims to promote inclusion, equity, and representation of all Hispanic/Latine subgroups, a population that has been historically misrepresented in health research. In this paper we describe the role of the SLCC in advocating for Hispanic/Latine families within the study, ensuring their inclusion from inception. This report also provides an overview of the SLCC organization, workflow, challenges and lessons learned thus far to reduce stigma and improve study outcomes, highlighting recruitment and retention strategies for the Hispanic/Latine population, and expanding outreach to promote inclusion across diverse Hispanic/Latine subgroups in the United States.

From multilevel to trans-level interventions: A critical next step for creating sustainable social change to improve mental health

Eliminating mental health disparities requires simultaneously addressing numerous determinants of health, including social inequities. Although emphasis on multilevel change is growing, interventions typically involve separate efforts or people focusing on each level. We propose a trans-level conceptual model for mental health intervention that simultaneously facilitates change across multiple intersecting levels with four guiding principles: (1) emphasis on structural change; (2) involvement of people experiencing health and social inequities in achieving structural change by addressing the necessary preconditions of access to resources for basic needs, community membership and belonging, and knowledge or information to participate in social change efforts; (3) valuing and building on the expertise and strengths of individuals, families, and communities experiencing health inequities; and (4) dismantling unequal power dynamics of helping relationships through a focus on mutual learning and support and cocreation of change. Tracing the trajectory of a 23-year community-based mental health intervention partnership (the Refugee and Immigrant Well-Being Project), we illustrate the trans-level intervention model and describe its impact on individual mental health and sustainable change at multiple levels.

The utility of measuring daily hassles and uplifts in understanding outcomes to treatments for major depressive disorder

Little is known about the effects of common daily experiences in patients with major depressive disorder (MDD). The Daily Hassles and Uplifts Scale (HUPS) was assessed in 142 treatment-naïve adult MDD outpatients randomized to 12 weeks of treatment with either antidepressant medication (ADM) or Cognitive Behavior Therapy (CBT). Three HUPS measures were analyzed: hassle frequency (HF), uplift frequency (UF), and the mean hassle intensity to mean uplift intensity ratio (MHI:MUI). Remission after treatment was not predicted by these baseline HUPS measures and did not moderate outcomes by treatment type. In contrast, HUPS measures significantly changed with treatment and were impacted by remission status. Specifically, HF and MHI:MUI decreased and UF increased from baseline to week 12, with remission leading to significantly greater decreases in HF and MHI:MUI compared to non-remission. ADM-treated patients demonstrated significant improvements on all three HUPS measures regardless of remission status. In contrast, remitters to CBT demonstrated significant improvements in HF and MHI:MUI but not UF; among CBT non-remitters the only significant change was a reduction in HF. The changes in HUPS measures are consistent with how affective biases are impacted by treatments and support the potential value of increasing attention to positive events in CBT.

Functional connectivity of salience and affective networks among remitted depressed patients predicts episode recurrence

Recurrent episodes in major depressive disorder (MDD) are common but the neuroimaging features predictive of recurrence are not established. Participants in the Predictors of Remission in Depression to Individual and Combined Treatments (PReDICT) study who achieved remission after 12 weeks of treatment withcognitive behavior therapy, duloxetine, or escitalopram were prospectively monitored for up to 21 months for recurrence. Neuroimaging markers predictive of recurrence were identified from week 12 functional magnetic resonance imaging scans by analyzing whole-brain resting state functional connectivity (RSFC) using seeds for four brain networks that are altered in MDD. Neuroimaging correlates of established clinical predictors of recurrence, including the magnitude of depressive (Hamilton Depression Rating Scale), anxiety (Hamilton Anxiety Rating Scale) symptom severity at time of remission, and a comorbid anxiety disorder were examined for their similarity to the neuroimaging predictors of recurrence. Of the 344 patients randomized in PReDICT, 61 achieved remission and had usable scans for analysis, 9 of whom experienced recurrence during follow-up. Recurrence was predicted by: 1) increased RSFC between subcallosal cingulate cortex (SCC) and right anterior insula, 2) decreased RSFC between SCC and bilateral primary visual cortex, and 3) decreased RSFC between insula and bilateral caudate. Week 12 depression and anxiety scores were negatively correlated with RSFC strength between executive control and default mode networks, but they were not correlated with the three RSFC patterns predicting recurrence. We conclude that altered RSFC in SCC and anterior insula networks are prospective risk factors associated with MDD recurrence, reflecting additional sources of risk beyond clinical measures.

Understanding organizational perspectives from clinical research stakeholders involved in recruitment for biopharmaceutical-sponsored clinical trials in the United States: Recommendations for organizational initiatives to improve access and inclusivity in clinical research

Background

Equitable representation of racially and ethnically diverse subpopulations in clinical trials continues to be a problem, and trial participants do not always reflect the demographics of the population that the investigational product will be used to treat. The imperativeness of equitable representation of clinically relevant populations in clinical trials has implications for improving health outcomes, increasing knowledge about the safety and efficacy of new treatments across a wider population, and broadening access to innovative treatment options offered in clinical trials.

Methods

The purpose of this study was to understand organizational elements that are involved in the active implementation of racially and ethnically diverse inclusive recruitment practices for biopharmaceutical-funded trials in the United States. Semi-structured, in-depth interviews were used in this qualitative study. The interview guide was designed to explore the perceptions, practices and experiences of 15 clinical research site professionals related to recruiting diverse trial participants. Data analysis utilized an inductive coding process.

Results

Five themes were identified pertaining to the actual implementation of inclusive recruitment practices that provided explanations for organizational components: 1) provision of culturally appropriate, general disease and clinical trial education 2) organizational structure tailored for diverse recruitment 3) strong sense of mission related to improving healthcare through clinical research 4) culture of inclusion 5) inclusive recruitment practices evolving based on learning.

Conclusion

The findings from this study offer insight into improving access to clinical trials by focusing on organizational change initiatives.

A randomized clinical trial of prolonged exposure and applied relaxation for the treatment of Latinos with posttraumatic stress disorder

Robust evidence supports the use of prolonged exposure therapy (PE) as a first-line treatment for posttraumatic stress disorder (PTSD). However, Latinos have not benefitted equally from advancements in the treatment of PTSD and continue to face barriers to receiving care. There is consensus that it is necessary to support the expansion of high-quality culturally and linguistically appropriate treatment to address disparities experienced by racial and ethnic minorities in behavioral health care. The current study was a randomized controlled trial comparing a culturally adapted PE intervention with applied relaxation (AR) among Spanish-speaking Latinos with PTSD in Puerto Rico. Eligible participants (N = 98) were randomly assigned to PE (n = 49) or AR (n = 49). Both treatments included 12-15 weekly sessions each lasting 60-90 min. The primary outcome, clinician-rated PTSD symptom severity, was assessed using the Clinician-Administered PTSD Scale for DSM-5 at baseline, posttreatment, and 3-month follow-up. Secondary outcomes were assessed using the Patient Health Questionnaire and State-Trait Anxiety Inventory. Results showed a large within-group effect of treatment on PTSD symptoms, PE: d = 1.29, 95% CI [1.12, 2.05]; AR: d = 1.38, 95% CI [1.21, 2.19]. The between-group effect on PTSD symptoms was small, d = -0.09, 95% CI [-0.48, 0.31]. Participants in both treatment conditions reported significant decreases in PTSD symptoms from baseline to follow-up; additionally, significant within-group reductions in depression and anxiety symptoms were observed. These findings underscore the potential benefit of PE and AR for the treatment of Spanish-speaking Latinos with PTSD.

Collegiate Student-Athlete Psychological Distress and Counseling Utilization During COVID-19

The onset of COVID-19 and cancellation of collegiate sports may have exacerbated student-athletes’ psychological distress. Within a national sample of collegiate athletes (N = 5,755; 66.7% women), we determined how gender and race related to rates of depression, stress, and counseling use at the beginning of the pandemic (April/May 2020). Overall, 26.5% (n = 1,526) and 10.6% (n = 612) endorsed clinical levels of depression and stress, respectively; 25.1% (n = 1,443) and 69.7% (n = 4,014) reported subclinical levels. Few athletes (2.3%–17.1%) reported counseling use before or after the onset of COVID-19; those who did reported higher levels of depression and stress than those who never sought services. The female athletes reported higher rates of depression, stress, and counseling use than the male athletes. There were no race effects. Athletic departments must address their student-athletes’ psychological distress by facilitating a higher use of mental health services.

Patient Satisfaction with a Psychology Consultation-Liaison Service at an Academic Medical Center

One to two-thirds of all medically admitted patients have comorbid psychiatric concerns. To address the cognitive, behavioral, and emotional factors that affect medical hospitalization, psychological or psychiatric consultation-liaison (CL) services are consulted. The current study was designed to understand patient satisfaction with a CL psychology service and how it was associated with satisfaction with overall hospitalization, taking into consideration relevant factors. Adults medically admitted to an academic teaching hospital (N = 220), who were seen at least once by the CL psychology service, completed satisfaction and demographic questionnaires. Most patients reported being satisfied with the CL psychology service, with women reporting higher satisfaction than men. Satisfaction with the CL psychology service was associated with satisfaction with overall hospitalization, but did not differ based on age, race/ethnicity, education, income, length of stay, number of visits, or presence of psychiatric diagnosis. The results suggest that CL psychology services may contribute to improving overall patient experience.

Concordance between clinician-rated and patient reported outcome measures of depressive symptoms in treatment resistant depression

BACKGROUND

Calls to implement measurement-based care (MBC) in psychiatry are increasing. A recent Cochrane meta-analysis concluded that there is insufficient evidence that routine application of patient reported outcomes (PROs) improves treatment outcomes for common psychiatric disorders. There is a particular paucity of this information in patients with treatment resistant depression (TRD).

METHODS

A TRD sample (n = 302) and a treatment-naïve sample with major depression (n = 344) were assessed for the level of agreement in depression severity between two PROs (the Beck Depression Inventory, BDI, and the Quick Inventory of Depressive Symptomatology Self-report, QIDS-SR) and two Clinician Rated (CRs) measures (Hamilton Depression Rating Scale, HDRS, and the Montgomery-Asberg Depression Rating Scale, MADRS).

RESULTS

Correlations between CR and PRO total scores in the TRD sample ranged from 0.57 (HDRS-QIDS-SR) to 0.68 (MADRS-BDI), reflecting a moderate-to-strong relationship between assessment tools. Correlations in the treatment naïve sample were non-significantly lower for most comparisons, ranging from 0.51 (HDRS-QIDS-SR) to 0.64 (MADRS-BDI). Few predictors of discordance between CRs and PROs were identified, though chronicity of the current episode in treatment-naïve patients was associated with greater agreement.

LIMITATIONS

Inter-rater reliability of the clinician interviews was conducted separately within the two studies so we could not determine the reliability between the two groups of raters used in the studies.

CONCLUSION

Findings generally supported acceptably high levels of agreement between patient and clinician ratings of baseline depression severity. More work is needed to determine the extent to which PROs can improve outcomes in MBC for depression and, more specifically, TRD.

Somatic symptoms in treatment-naïve Hispanic and non-Hispanic patients with major depression

BACKGROUND

Somatic complaints are a major driver of health care costs among patients with major depressive disorder (MDD). Some epidemiologic and clinical data suggest that Hispanic and non-Hispanic Black patients with MDD endorse higher levels of somatic symptoms than non-Hispanic White patients.

METHODS

Somatic symptoms in 102 Hispanic, 61 non-Hispanic Black, and 156 non-Hispanic White patients with treatment-naïve MDD were evaluated using the somatic symptom subscale of the Hamilton anxiety rating scale (HAM-A). The other seven items of the HAM-A comprise the psychic anxiety subscale, which was also evaluated across ethnicities.

RESULTS

Hispanic patients reported significantly greater levels of somatic symptoms than non-Hispanic patients, but levels of psychic anxiety symptoms did not differ by ethnicity. Levels of somatic symptoms did not significantly differ between Black and White non-Hispanic patients. Within the Hispanic sample, somatic symptom levels were higher only among those who were evaluated in Spanish; Hispanics who spoke English showed no significant differences versus non-Hispanics.

CONCLUSIONS

In this medically healthy sample of patients with MDD, monolingual Spanish-speaking Hispanic patients endorsed high levels of somatic symptoms. Clinicians should be mindful that the depressive experience may manifest somatically and be judicious in determining when additional medical work-up is warranted for somatic complaints.

The State of Lupus Clinical Trials: Minority Participation Needed

In the United States, the reported prevalence of lupus is 100,000 to 500,000 patients. Lupus disproportionately affects minority populations, including African Americans and Latinos, and the associated health disparities are substantial. Women are at a higher risk of lupus than men and lupus prevalence is the highest in African Americans and Latinos compared to non-Hispanic whites. African Americans and Latinos also have increased disease symptom severity, experience more lupus-related complications, and have a two- to three-fold mortality rate compared to non-Hispanic Whites. Lupus clinical trials offer opportunities for quality care and can result in new treatment options, but African Americans and Latinos are underrepresented in clinical trials because of substantial patient- and provider-side barriers. In conjunction with the limited knowledge of clinical trials that potential participants may have, the healthcare staff approaching participants have limited time to adequately educate and explain the aspects of clinical trials. Indeed, ninety percent of clinical trials fail to meet their recruitment goals on time, so a multi-faceted approach is necessary to address the issue of low minority participation in clinical trials.

Lessons Learned in Clinical Research Recruitment of Immigrants and Minority Group Members with First-Episode Psychosis

Recruitment of immigrants and racial and ethnic minorities with first-episode psychosis (FEP) for research studies presents numerous challenges. We describe methods used to recruit 43 U.S. Latinos with FEP and their family caregivers (n = 41) participating in a study to reduce duration of untreated psychosis. A key challenge was that patients were not continuing treatment at an outpatient clinic, as initially expected. To facilitate identification of patients prior to outpatient care, we collaborated with clinic and hospital administrators. Many patients and families were grappling with the aftermath of a hospitalization or adjusting to a diagnosis of a serious mental illness. A considerable amount of time was devoted to addressing participants' concerns and when possible, facilitating needed services. Our experience underscores the importance of establishing long-term relationships through multiple contacts with patients, families, and stakeholders to address recruitment barriers among underserved groups with FEP.

Pilot randomized controlled trial of a Spanish-language Behavioral Activation mobile app (¡Aptívate!) for the treatment of depressive symptoms among united states Latinx adults with limited English proficiency

BACKGROUND

To address the need for disseminable, evidence-based depression treatment options for Latinx adults with limited English proficiency (LEP), our team developed ¡Aptívate!, a Spanish-language Behavioral Activation self-help mobile application. Primary aims of this study were to: 1) examine feasibility and uptake of ¡Aptívate! among depressed Latinx adults with LEP and 2) preliminarily examine ¡Aptívate! efficacy for depression treatment.

METHODS

Participants (N = 42) with elevated depressive symptoms were randomized 2:1:1 to: 1) ¡Aptívate! (n = 22), 2) an active control Spanish-language app ("iCouch CBT"; n = 9), or 3) Treatment As Usual (i.e., no app; n = 11). Feasibility was assessed via self-reported app utilization and app analytics data. Depressive symptoms were assessed weekly for eight weeks via self report.

RESULTS

All ¡Aptívate! participants used the app at least once, 81.8% of participants used the app ≥8 times, and 36.4% of participants used the app ≥56 times. Weekly retention was strong: 72.7% and 50% of participants continued to use the app at one- and two-months post-enrollment, respectively. Generalized Estimating Equation models indicated a significant interaction between time and treatment, such that ¡Aptívate! participants reported significantly lower depressive symptoms over time than TAU. Depressive symptoms did not differ on average across time between the iCouch and TAU conditions, nor between iCouch and ¡Aptívate!.

LIMITATIONS

Limitations include small sample size, limited follow-up, and lack of analytics data for the active control condition.

CONCLUSIONS

With further research, ¡Aptívate! may offer a feasible, efficacious approach to extend the reach of evidence-based depression treatment for Latinx adults with LEP.

Mental health stigma in depressed Latinos over the course of therapy: Results from a randomized controlled trial

OBJECTIVE

The current study examined the course, correlates, and predictors of mental health stigma among depressed, Spanish-speaking Latinos that were receiving treatment. This population faces significant disparities in mental health treatment and carries high levels of mental health stigma.

METHOD

The study utilized data generated from a randomized clinical trial (N = 46) that evaluated the efficacy of Behavioral Activation and Supportive Counseling for depression among Latinos.

RESULTS

Mental health stigma decreased over time; these decreases were more pronounced among individuals who were randomized to Supportive Counseling. Mental health stigma was positively associated with depressive symptoms and therapeutic alliance over time. Mental health stigma was not related to treatment attrition.

CONCLUSIONS

These preliminary findings indicate that mental health stigma continues to be relevant among individuals who are actively participating in treatment. Receiving mental health treatment may be sufficient to dispel some of the stigmatizing views endorsed by underserved clinical populations.

The prevalence and predictors of mental health diagnoses and suicide among U.S. college students: Implications for addressing disparities in service use

BACKGROUND

The college years represent a period of increased vulnerability for a wide range of mental health (MH) challenges. The onset of common psychiatric conditions occurs during this period of development. Increases in depression, anxiety, and suicidality among U.S. college students have been observed. This study identified prevalence and correlates of MH diagnoses and suicidality in a recent sample of U.S. college students.

METHODS

The Spring 2015 American College Health Association-National College Health Assessment (ACHA-NCHA) survey assessed MH diagnoses and suicidality from U.S. undergraduate students (n = 67,308) across 108 institutions.

RESULTS

Stress was strongly associated with a greater likelihood of suicide attempts and MH diagnoses, even among students reporting 1-2 stressful events (OR [odds ratio] range 1.6-2.6, CI [confidence interval] = 1.2-3.2). Bisexual students were more likely to report MH diagnoses and suicidality, compared to heterosexual and gay/lesbian students (OR range 1.5-3.9, CI = 1.8-4.3), with over half engaging in suicidal ideation and self-harm, and over a quarter reporting suicide attempts. Transgender students reported a higher rate of MH diagnoses and suicidality relative to females (OR range 1.9-2.4, CI = 1.1-3.4). Racial/ethnic minority students were generally less likely to report MH diagnoses relative to Whites, although the likelihood for suicidality was mixed.

CONCLUSIONS

The high rate of multiple stress exposures among the U.S. college population and the high impacts of stress on MH and suicidality point to an urgent need for service utilization strategies, especially among racial/ethnic, sexual, or gender minorities. Campuses must consider student experiences to mitigate stress during this developmental period.

Evaluation of perceptions and knowledge of mental illness in the United States through crowdsourcing

Introduction

Crowdsourcing is a method of data collection with possible benefits in assessing perceptions of mental illness in a large US population.

Methods

The objective was to describe perceptions and trends of stigma surrounding mental illness in the United States using crowdsourcing. An online survey was conducted evaluating adults in the United States recruited via the online resource Amazon Mechanical Turk. Questions evaluated demographics and perceptions of mental illness. Survey data were adjusted for demographic variables and compared via logistic regression.

Results

Respondents (n = 1422) were predominately 18 to 30 years of age (n = 743; 52.3%) and white (n = 1101; 77.4%). Over half reported an individual close to them had mental illness (n = 932; 65.5%), and more than one quarter (n = 397; 27.9%) reported having a current or previous mental illness. Non-whites were less likely to agree that: medications are effective (odds ratio [OR] 0.63); they would be comfortable around a coworker with mental illness (OR 0.66); and mental illness is inheritable (OR 0.74). They are also more likely to agree that mental illness is preventable (OR 1.49). Individuals reporting mental illness were more likely to agree that medications (OR 1.34; 95% confidence interval 1.03 to 1.74) and talk therapy (OR 1.46; 95% confidence interval 1.12 to 1.90) are effective. Those reporting some or no college were more likely to agree that the United States has good access to mental health treatment.

Discussion

Crowdsourcing may be an effective way to obtain information regarding demographics, stigma, and mental illness. Personal experiences with mental illness, ethnicity, and educational level appear to continue to impact perceptions of mental illness.

Alcohol Use Severity Among Adult Hispanic Immigrants: Examining the Roles of Family Cohesion, Social Support, and Gender

BACKGROUND

This study examined (a) the direct association of family cohesion on alcohol use severity among adult Hispanic immigrants; (b) the indirect association of family cohesion on alcohol use severity via social support; and (c) if gender moderates the direct and indirect associations between family cohesion and alcohol use severity.

METHOD

Mediation and moderation analyses were conducted on a cross-sectional sample of 411 (men = 222, women = 189) participants from Miami-Dade, Florida.

RESULTS

Findings indicate that higher family cohesion was directly associated with higher social support and lower alcohol use severity. Higher social support was also directly associated with lower alcohol use severity. Additionally, family cohesion had an indirect association with alcohol use severity via social support. Moderation analyses indicated that gender moderated the direct association between family cohesion and alcohol use severity, but did not moderate the indirect association.

CONCLUSIONS

Some potential clinical implications may be that strengthening family cohesion may enhance levels of social support, and in turn, lower alcohol use severity among adult Hispanic immigrants. Furthermore, strengthening family cohesion may be especially beneficial to men in efforts to lower levels of alcohol use severity.

A Survey of Parents with Children on the Autism Spectrum: Experience with Services and Treatments

INTRODUCTION

Autism spectrum disorders (ASD) are lifelong neurodevelopmental disorders, and little is known about how parents address the health and psychosocial consequences of ASD. Few studies have examined use of various treatments and services in a large, diverse sample of children with ASD and their families.

OBJECTIVE

This paper presents methods to create an autism research resource across multiple large health delivery systems and describes services and treatments used by children with ASD and their families.

METHODS

Four study sites conducted a Web survey of parents of children and adolescents with ASD who were members of Kaiser Permanente. We tabulated data distributions of survey responses and calculated χ² statistics for differences between responders and nonresponders.

RESULTS

The children of the 1155 respondents were racially and ethnically diverse (55% white, 6% black, 5% Asian, 9% multiracial, 24% Hispanic) and representative of the total population invited to participate with respect to child sex (83% male), child age (57% < 10 years), and ASD diagnosis (64% autistic disorder). The most frequently used services and treatments were Individualized Education Programs (85%), family physician visits (78%), and occupational and speech therapy (55% and 60%, respectively). Home-based programs frequently included implementation of social skills training (44%) and behavior management (42%). Prescription medication use was high (48%). Caregivers reported disruption of personal and family routines because of problem behaviors.

CONCLUSION

These survey data help to elucidate parents' experiences with health services for their children with ASD and serve as a potential resource for future research.

Follow-up of monotherapy remitters in the PReDICT study: Maintenance treatment outcomes and clinical predictors of recurrence

OBJECTIVE

This study followed remitted patients from a randomized controlled trial of adults with major depressive disorder (MDD). The aims were to describe rates of recurrence and to evaluate 3 clinical predictor domains.

METHOD

Ninety-four treatment-naïve patients (50% female; Mage = 38.1 years; 48.9% White; 30.9% Hispanic) with MDD who had remitted to 12-week monotherapy (escitalopram, duloxetine, or cognitive behavior therapy [CBT]) participated in a 21-month maintenance phase (i.e., continued medication or 3 possible CBT booster sessions per year). Recurrence was assessed quarterly, and the clinical predictors were the following: 2 measures of residual depressive symptoms, 1 measure of lifetime depressive episodes, and 2 measures of baseline anxiety. Survival analysis models evaluated recurrence rates, and regression models evaluated the predictors.

RESULTS

Among all patients, 15.5% experienced a recurrence, and the survival distributions did not statistically differ among treatments. Residual depressive symptoms on the Hamilton Depression Rating Scale at the end of monotherapy were associated with increased risk for recurrence (hazard ratio = 1.31, 95% confidence interval [CI: 1.02, 1.67], Wald χ2 = 4.41, p = .036), and not having a comorbid anxiety disorder diagnosis at study baseline reduced the risk of recurrence (hazard ratio = .31, 95% CI [.10, .94], Wald χ2 = 4.28, p = .039).

CONCLUSIONS

The study supported the benefits of maintenance treatment for treatment-naïve patients who remitted to initial monotherapy; nevertheless, remitted patients with a comorbid anxiety disorder diagnosis at the beginning of treatment or residual depressive symptoms after initial treatment were at risk for poorer long-term outcomes.

Effects of Patient Preferences on Outcomes in the Predictors of Remission in Depression to Individual and Combined Treatments (PReDICT) Study

OBJECTIVE

The Predictors of Remission in Depression to Individual and Combined Treatments [PReDICT] study aimed to identify clinical and biological factors predictive of treatment outcomes in major depressive disorder among treatment-naive adults. The authors evaluated the efficacy of cognitive-behavioral therapy (CBT) and two antidepressant medications (escitalopram and duloxetine) in patients with major depression and examined the moderating effect of patients' treatment preferences on outcomes.

METHOD

Adults aged 18-65 with treatment-naive major depression were randomly assigned with equal likelihood to 12 weeks of treatment with escitalopram (10-20 mg/day), duloxetine (30-60 mg/day), or CBT (16 50-minute sessions). Prior to randomization, patients indicated whether they preferred medication or CBT or had no preference. The primary outcome was change in the 17-item Hamilton Depression Rating Scale (HAM-D), administered by raters blinded to treatment.

RESULTS

A total of 344 patients were randomly assigned, with a mean baseline HAM-D score of 19.8 (SD=3.8). The mean estimated overall decreases in HAM-D score did not significantly differ between treatments (CBT: 10.2, escitalopram: 11.1, duloxetine: 11.2). Last observation carried forward remission rates did not significantly differ between treatments (CBT: 41.9%, escitalopram: 46.7%, duloxetine: 54.7%). Patients matched to their preferred treatment were more likely to complete the trial but not more likely to achieve remission.

CONCLUSIONS

Treatment guidelines that recommend either an evidence-based psychotherapy or antidepressant medication for nonpsychotic major depression can be extended to treatment-naive patients. Treatment preferences among patients without prior treatment exposure do not significantly moderate symptomatic outcomes.

The Structure of Personality Disorders within a Depressed Sample: Implications for Personalizing Treatment

BACKGROUND

Personality disorders (PDs) and major depressive disorder (MDD) are both significant public health burdens. They are frequently comorbid, and this comorbidity predicts poorer treatment outcomes and lower maintenance of treatment effects. Although there is growing consensus on the structure of personality pathology in non-depressed individuals, there is limited research on the structure of personality pathology in individuals experiencing MDD.

METHOD

As part of the Predictors of Remission in Depression to Individual and Combined Treatment (PReDICT) randomized controlled trial, 192 treatment-naïve subjects meeting DSM-IV-TR criteria for MDD completed the International Personality Disorder Examination (IPDE). Using this sample, a principal components analysis explored the factor structure of the IPDE.

RESULTS

A three-factor model comprised three factors labeled "NADA" (Negative Affectivity, Disinhibition, and Antagnoism)," "Social Anxiety," and "Antisociality." Factor intercorrelations were small-to-moderate, and the sum score of the three factors was highly correlated (r = .94) with the total IPDE score.

LIMITATIONS

Personality pathology was assessed with one instrument, and sample size was smaller than ideal for factor analytic research. \.

CONCLUSIONS

Consistent with prior factor-analytic findings, a three-factor solution provided the most clinically and theoretically useful model. This finding lends support for the personality disorders retained in DSM-5 and some support for a model of personality pathology aligned with the personality traits found in the leading nonclinical models of personality. The obtained factors are potential moderators of clinical interventions and may serve as an avenue to personalizing treatments.

Racial Differences Among Factors Associated with Participation in Clinical Research Trials

OBJECTIVE

To identify whether racial differences exist among various factors associated with patients' decision to participate in clinical research trials.

METHODS

A self-administered, IRB-approved survey was utilized with inclusion criteria requiring subjects to be 18 years of age or older, having active patient status and ability to complete the survey without assistance. Subjects were asked to rate potential influential motivators, barriers, and facilitators on a "no influence" (0) to "most influence" (4) scale for participation in research that tests a new drug or device. Kruskal-Wallis testing was used to identify factors significantly associated with race.

RESULTS

Analysis included 1643 surveys: 949 (57.8 %) Caucasian; 217 (13.2 %) African-American; 317 (19.3 %) Hispanic; 62 (3.8 %) Multiracial; and 98 (6.0 %) "Other" minorities. Statistically significant differences (p ≤ .02) by race were found for five out of ten motivating factors. "How well the research study is explained to me" had the highest mean value for all races except other minorities, for whom "Knowledge learned from my participation will benefit someone in the future" scored highest. "Risk of unknown side-effects" was the greatest barrier for all races.

CONCLUSION

Racial differences exist not only between Caucasians and Minorities for the factors associated with their clinical trial participation, but also among different minority races themselves. To promote diversity in research, recruitment strategies for each individual race should be customized based on what matters to the target population.

Will they participate? Predicting patients' response to clinical trial invitations in a pediatric emergency department

Objective (1) To develop an automated algorithm to predict a patient’s response (ie, if the patient agrees or declines) before he/she is approached for a clinical trial invitation; (2) to assess the algorithm performance and the predictors on real-world patient recruitment data for a diverse set of clinical trials in a pediatric emergency department; and (3) to identify directions for future studies in predicting patients’ participation response.

Materials and Methods We collected 3345 patients’ response to trial invitations on 18 clinical trials at one center that were actively enrolling patients between January 1, 2010 and December 31, 2012. In parallel, we retrospectively extracted demographic, socioeconomic, and clinical predictors from multiple sources to represent the patients’ profiles. Leveraging machine learning methodology, the automated algorithms predicted participation response for individual patients and identified influential features associated with their decision-making. The performance was validated on the collection of actual patient response, where precision, recall, F-measure, and area under the ROC curve were assessed.

Results Compared to the random response predictor that simulated the current practice, the machine learning algorithms achieved significantly better performance (Precision/Recall/F-measure/area under the ROC curve: 70.82%/92.02%/80.04%/72.78% on 10-fold cross validation and 71.52%/92.68%/80.74%/75.74% on the test set). By analyzing the significant features output by the algorithms, the study confirmed several literature findings and identified challenges that could be mitigated to optimize recruitment.

Conclusion By exploiting predictive variables from multiple sources, we demonstrated that machine learning algorithms have great potential in improving the effectiveness of the recruitment process by automatically predicting patients’ participation response to trial invitations.

Anxious-depression among Hispanic/Latinos from different backgrounds: results from the Hispanic Community Health Study/Study of Latinos (HCHS/SOL)

BACKGROUND

Anxious-depression is a constellation of symptoms, frequently encountered among patients in primary care centers. There is a need to study how anxious-depression presents among Hispanic/Latinos of different backgrounds.

OBJECTIVE

To study the construct of anxious-depression among 16,064 Hispanic/Latinos of different backgrounds participating in the Hispanic Community Health Study/Study of Latinos. We hypothesized that Hispanic/Latinos will cluster in 3 classes: low anxiety/high depression, high anxiety/low depression and a combined anxious-depression construct.

METHODS

Using latent profile analysis, symptoms of depression and anxiety measured by the 10-item Center for Epidemiologic Studies Depression Scale and 10-item State-Trait Anxiety Inventory were evaluated to determine if an anxious-depression typology would result. A multinomial logistic regression analysis explored the association of the 3-class solution with different Hispanic/Latino backgrounds controlling for age, gender, language, education and income.

RESULTS

A 3-class mixed anxious-depression structure emerged with 10% of Hispanic/Latinos in the high, 30% in the moderate and 60% in the low anxious-depression category. After adjusting for age, gender, language preference, income and education, individuals of Puerto Rican background were more likely to experience high (OR = 1.79, p < 0.05) and moderate (OR = 1.36, p < 0.05) (vs. low) anxious-depression symptomatology compared to those of Mexican background. Individuals of Central American and South American background were less likely to experience high (OR = 0.68, p < 0.05) and moderate (OR = 0.8, p < 0.05) (vs. low) anxious-depression compared to those of Mexican background.

CONCLUSION

Anxious-depression symptomatology varied among this sample of Hispanic/Latino groups. These classes should be investigated as to their relationship with different health outcomes relevant to the Hispanic/Latino of different backgrounds.

Differences in pain subtypes between Hispanic and non-Hispanic white women with chronic vulvar pain

OBJECTIVES

Compared with non-Hispanic Whites, Hispanic women have significantly higher prevalence of chronic vulvar pain (CVP), which is known to have heterogeneous subtypes. However, it is not known whether subtypes differ by ethnicity, and improved understanding of subtypes may allow for targeted clinical assessment and therapies. We examined subtypes to determine whether they differed by ethnicity.

METHODS

Data were from 1,551 women who reported chronic vulvar pain consistent with vulvodynia in a population-based, cross-sectional study of women from the Minneapolis/St. Paul metropolitan area, during the years 2010-2013, who returned a validated screener survey about vulvar pain.

RESULTS

Among women with CVP, Hispanics reported more primary vulvodynia (adjusted [adj.] risk ratio=1.47; p<0.01), defined as pain with first intercourse or tampon use, and tended to be more likely to describe a burning pain (adj. risk ratio=1.45; p=0.06). Hispanic women with CVP were 17% more likely than non-Hispanic Whites with CVP to have their pain alleviated with some type of behavior/remedy (p=0.01); for example, among the subgroup of women with CVP who used yeast cream, Hispanics more often reported benefit to their pain (adj. risk ratio=1.51; p<0.01).

DISCUSSION

We examined women with CVP and found that in comparison to their non-Hispanic White counterparts, Hispanic women are more likely to report a burning sensation and more likely to have primary vulvodynia, a subtype that is associated with great burden on the lives of affected women.
