Primary care-based screening and recruitment for an adolescent depression prevention trial: Contextual considerations during a youth mental health crisis.

Background: Rising rates of adolescent depression in the wake of COVID-19 and a youth mental health crisis highlight the urgent need for accessible mental healthcare and prevention within primary care. Digital mental health interventions (DMHIs) may increase access for underserved populations. However, these interventions are not well studied in adolescents, nor healthcare settings. The purpose of this study was to identify barriers and facilitators to screening and recruitment activities for PATH 2 Purpose (P2P): Primary Care and Community-Based Prevention of Mental Disorders in Adolescents, a multi-site adolescent depression prevention trial comparing two digital prevention programs within four diverse health systems in two U.S. states. Method: This qualitative study is a component of a larger Hybrid Type I trial. We conducted semi-structured key informant interviews with clinical and non-clinical implementers involved with screening and recruitment for the P2P trial. Informed by the Consolidated Framework for Implementation Research (CFIR), interviews were conducted at the midpoint of the trial to identify barriers, facilitators, and needed adaptations, and to gather information on determinants that may affect future implementation. Findings: Respondents perceived the P2P trial as valuable, well aligned with the mission of their health systems. However, several barriers were identified, many of which stemmed from influences outside of the healthcare settings. Universal and site-specific outer setting influences (COVID-19 pandemic, youth mental health crisis, local community conditions) interacted with Inner Setting and Innovation domains to create numerous challenges to the implementation of screening and recruitment. Conclusion: Our findings emphasize the need for ongoing, comprehensive assessment of dynamic inner and outer setting contexts prior to and during implementation of clinical trials, as well as flexibility for adaptation to unique clinical contexts. The CFIR is useful for assessing determinants during times of rapid inner and outer setting change, such as those brought on by the COVID-19 pandemic, youth mental health crisis, and the corresponding exacerbation of resource strain within healthcare settings.

Adolescent mental health problems such as depression, anxiety, and suicidal behavior are prevalent, and have been increasing in the wake of the COVID-19 pandemic. In 2021, the Surgeon General declared a "youth mental health crisis," and the American Academy of Pediatrics issued a joint statement declaring a national youth mental health emergency. Accessible, affordable, evidence-based interventions are needed to prevent the development of depressive symptoms into major depressive disorder. The integration of digital mental health interventions (DMHIs) into primary care may reduce access barriers. Primary care clinical settings are well suited to identify individuals at-risk for developing depression, and facilitate preventive treatment planning. While preventive DMHIs for adolescents exist, more evidence is needed on their effectiveness, and how to best integrate them into healthcare. Our study team interviewed primary care-based staff, administrators, and clinical providers involved with implementing screening and recruitment activities for the P2P trial, a randomized controlled trial comparing the effectiveness of two digital depression prevention programs. Respondents shared experiences with trial recruitment in their settings, including perceived challenges. Our findings suggest that multiple factors influenced recruitment, including influences situated outside of the clinical settings, such as the COVID-19 pandemic and worsening adolescent mental health. These influences interacted with factors affecting recruitment inside of health clinics, such as demands on staff and provider time, and perceived importance of prevention programming versus other initiatives. Identifying these influencing factors during the trial helps to inform considerations for planning future integration of similar programs into primary care settings.

Internet-based cognitive behavioral therapy intervention for youth with type 1 diabetes and depressive symptoms: a pilot and feasibility study.

Depression is more common in youth with type 1 diabetes (T1D) compared to youth without diabetes. This study aims to assess the efficacy of Competent Adulthood Transition with Cognitive Humanistic and Interpersonal Teaching (CATCH-IT), an internet-based cognitive behavioral therapy (CBT) intervention, in adolescents with T1D and depressive symptoms. Adolescents (13 to 17 years old) with T1D and mild (score 5-9) or moderate (score 10-14) depressive symptoms on Patient Health Questionnaire-Adolescent (PHQ-A) screening assessment were recruited to participate and received online access to the CATCH-IT modules for 6 months (requested to complete in 12 weeks). Statistical analyses included paired t-test for changes in Center for Epidemiologic Studies Depression Scale (CES-D), PHQ-A, Problem Areas in Diabetes-Teen version (PAID-T), and hemoglobin A1c (HbA1c). Nineteen patients were consented, 15 met inclusion criteria and received the intervention. In the seven participants that completed the modules, there was a trend towards improvements in PHQ-A, CES-D and HbA1c. Participants provided robust qualitative feedback on the modules and areas for improvement in subsequent iterations, such as inclusion of diabetes-related content. Given the prevalence of depression in diabetes, feasible, low resource interventions are needed. Internet programs such as CATCH-IT can serve as an effective first line intervention in this high-risk population. A modified version of CATCH-IT tailored for adolescents with T1D may be beneficial in this patient population.

BEhavioral Health Stratified Treatment (B.E.S.T.) to optimize transition to adulthood for youth with intellectual and/or developmental disabilities.

Youth with intellectual and/or developmental disabilities (IDD) often struggle with depression and anxiety, which adversely impacts transition to adulthood. Integrated behavioral health care coordination, wherein care coordinators and behavioral health specialists collaborate to provide systematic, cost-effective, patient-centered care, is a promising strategy to improve access to behavioral health services and address factors that impact transition to adulthood, including depression/anxiety symptoms. Current care coordination models (e.g., Title V Maternal and Child Health Bureau [MCHB]) do not include behavioral health services. The CHECK (Coordinated HealthCarE for Complex Kids) mental health model, hereby refined and renamed BEhavioral Health Stratified Treatment (B.E.S.T.), is a behavioral health intervention delivery program designed for integration into care coordination programs. This study aims to determine whether an integrated behavioral health care coordination strategy (i.e., MCHB care coordination plus B.E.S.T.) would be more acceptable and lead to better youth health and transition outcomes, relative to standard care coordination (i.e., MCHB care coordination alone). Results would guide future investment in improving outcomes for youth with IDD. This study is a two-arm randomized clinical trial of 780 transition-aged youth with IDD (13-20 years) to evaluate the comparable efficacy of MCHB Care Coordination alone vs. MCHB Care Coordination plus B.E.S.T. on the following outcomes: 1) decreased symptoms and episodes of depression and anxiety over time; 2) improved health behaviors, adaptive functioning and health related quality of life; 3) increased health care transition (HCT) readiness; and 4) improved engagement and satisfaction with care coordination among stakeholders.

PATHway: Intervention optimization of a prevention program for adolescents at-risk for depression in the primary care setting.

With as many as 13% of adolescents diagnosed with depressive disorders each year, prevention of depressive disorders has become a key priority for the National Institute of Mental Health (NIMH). Currently, we have no widely available interventions to prevent these disorders. To address this need, we developed a multi-health system collaboration to develop and evaluate the primary care based technology "behavioral vaccine," Competent Adulthood Transition with Cognitive-Behavioral Humanistic and Interpersonal Therapy (CATCH-IT). The full CATCH-IT program demonstrated evidence of efficacy in prevention of depressive episodes in clinical trials. However, CATCH-IT became larger and more complex across trials, creating issues with adherence and scalability. We will use a multiphase optimization strategy approach to optimize CATCH-IT. The theoretically grounded components of CATCH-IT include: behavioral activation, cognitive-behavioral therapy, interpersonal psychotherapy, and parent program. We will use a 4-factor (2x2x2x2) fully crossed factorial design with N = 16 cells (25 per cell, after allowing 15% dropout) to evaluate the contribution of each component. Eligible at-risk youth will be high school students 13 through 18 years old, with subsyndromal symptoms of depression. The study design will enable us to eliminate non-contributing components while preserving efficacy and to optimize CATCH-IT by strengthening tolerability and scalability by reducing resource use. By reducing resource use, we anticipate satisfaction and acceptability will also increase, preparing the way for an implementation trial.

PATH 2 Purpose: Design of a comparative effectiveness study of prevention programs for adolescents at-risk for depression in the primary care setting.

The majority of mental, emotional, and behavioral (MEB) disorders have an initial onset before age 24, with 20% annual incidence, and with major depressive disorder (MDD) being the most common MEB. Health systems may be able to reduce costs by transitioning from the current treatment-focused model for MDD to a prevention model. However, evidence is needed for (1) the comparative effectiveness of a "scalable intervention" and (2) an implementation model for such a scalable intervention in the primary care setting. This paper describes a comparative effectiveness trial evaluating the efficacy of two evidence-based cognitive-behavioral prevention (CBP) programs: Teens Achieving Mastery over Stress (TEAMS), the "gold standard," group therapy model, and Competent Adulthood Transition with Cognitive Behavioral, Humanistic and Interpersonal Training (CATCH-IT), a scalable, self-directed, technology-based model. Eligible adolescents, age 13-19, are offered one of these two depression prevention programs across five health systems (30 clinics) in urban and suburban Chicago, IL, rural Western IL, and Louisville, KY. We are comprehensively evaluating patient-centered outcomes and stakeholder-valued moderators of effect versus baseline at two, six, 12, and 18-month assessment points. Using a hybrid clinical trial design that simultaneously examines the implementation process, the study is also assessing adolescents', parents', and providers' experiences (e.g., efficacy, time commitment, cultural acceptability) within each intervention approach.

Understanding Adolescent Expressions of Sadness: A Qualitative Exploration.

PURPOSE: Primary care providers are positioned to identify adolescents at risk for depression and prevent major depressive disorder. To identify subthreshold depression, we examined the language adolescents use to describe their symptoms. METHODS: Adolescents ages 13-18 with elevated levels on the Center for Epidemiologic Studies Depression (CES-D) scale and/or a history of depression who were part of a large randomized clinical trial to prevent depressive disorder were included. We used content analysis to analyze transcripts of semi-structured interviews. RESULTS: Saturation was reached at 37 interviews. Adolescents self-identified as African American (N = 15), Hispanic (N = 10), and White (N = 21). Three domains were revealed; external sources of stress, adolescent expressions of sadness, and seeking help and care. Within these domains, 12 distinct themes emerged contextualizing these domains. No variations in the expression of the themes identified for subthreshold depression were found between the three ethno-cultural groups. IMPLICATIONS FOR PRACTICE: Our study identifies, in adolescents' own words, how adolescents with subthreshold depression express feelings and cope with symptoms, and may guide primary care providers to recognize subthreshold depression early. These findings are a step toward filling the gap in the empirical literature needed to improve identification of adolescents at risk for depression in nonspecialist settings.

A multivariable analysis of childhood psychosocial behaviour and household functionality.

BACKGROUND: Social determinants of health play a vital role in population health. Awareness of household social factors and their impact on health can help health professionals to provide effective strategies in health promotion, especially for children and adolescents showing signs of psychosocial dysfunction. The objective of this study was to explore the association between parents' perceptions of the psychosocial behaviour of their children and the functionality of their household. METHODS: This cohort study analysed data from the Coordinated Health Care for Complex Kids programme. The sample included 293 parents of children aged 4-17 years with chronic conditions, and from urban, low-income families. Psychosocial behaviour of the child was measured using the Pediatric Symptom Checklist (PSC-17), which included subscales for internal, external, and attention symptoms. Household functionality was measured using the Confusion, Hubbub, and Order Scale. Responses to both assessments were scored in a standard manner. RESULTS: There was a significant association between parents' perceptions of the psychosocial behaviour of their children and the functionality of the home environment. The mean Confusion, Hubbub, and Order Scale scores in the home environment improved from baseline to the first reassessment (the period between the two assessments ranged from 4 to 8 months). Additionally, positive PSC-17 screening results of the children decreased by 11% in the first reassessment. The odds of having a positive PSC-17 screening result also decreased in the first reassessment after receiving interventions. CONCLUSION: The association between psychosocial dysfunction and household functionality indicates the importance of family-centred care and taking the home environment into consideration when administering health services to low-income children with chronic conditions. This study brings attention to the more hidden factors that influence child mental health, which must be addressed to improve care delivery and child health outcomes.

A Real-World Community Health Worker Care Coordination Model for High-Risk Children.

Health care systems across the United States are considering community health worker (CHW) services for high-risk patients, despite limited data on how to build and sustain effective CHW programs. We describe the process of providing CHW services to 5,289 at-risk patients within a state-run health system. The program includes 30 CHWs, six care coordinators, the Director of Care Coordination, the Medical Director, a registered nurse, mental health specialists, and legal specialists. CHWs are organized into geographic and specialized teams. All CHWs receive basic training that includes oral and mental health; some receive additional disease-specific training. CHWs develop individualized care coordination plans with patients. The implementation of these plans involves delivery of a wide range of social service and coordination support. The number of CHW contacts is determined by patient risk. CHWs spend about 60% of their time in an office setting. To deliver the program optimally, we had to develop multiple CHW job categories that allow for CHW specialization. We created new technology systems to manage operations. Field issues resulted in program changes to improve service delivery and ensure safety. Our experience serves as a model for how to integrate CHWs into clinical and community systems.

Effect of Internet-based Cognitive Behavioral Humanistic and Interpersonal Training vs. Internet-based General Health Education on Adolescent Depression in Primary Care: A Randomized Clinical Trial.

IMPORTANCE: Although 13-20% of American adolescents experience a depressive episode annually, no scalable primary care model for adolescent depression prevention is currently available. OBJECTIVE: To study whether CATCH-IT (Competent Adulthood Transition with Cognitive Behavioral Humanistic and Interpersonal Training) reduces the hazard for depression in at-risk adolescents identified in primary care, as compared to a general health education attention control (HE). DESIGN: The Promoting AdolescenT Health (PATH) study compares CATCH-IT and HE in a phase 3 single-blind multicenter randomized attention control trial. Participants were enrolled from 2012 to 2016 and assessed at 2, 6, 12, 18, and 24 months post-randomization. SETTING: Primary care. PARTICIPANTS: Eligible adolescents were 13-18 years with subsyndromal depression and/or history of depression and no current depression diagnosis or treatment. Of 2,250 adolescents screened for eligibility, 446 participants completed the baseline interview and 369 were randomized into CATCH-IT (n=193) and HE (n=176). INTERVENTIONS: CATCH-IT is a 20-module (15 adolescent modules, 5 parent modules) online psychoeducation course that includes a parent program, supported by three motivational interviews. MAIN OUTCOMES AND MEASURES: Time-to-event for depressive episode; depressive symptoms at 6 months. RESULTS: Mean age was 15.4 years, and 68% were female; 28% had both a past episode and subsyndromal depression; 12% had a past episode only, 59% had subsyndromal depression only, and 1% had borderline subsyndromal depression. The outcome of time-to-event favored CATCH-IT but was not significant with intention-to-treat analyses (N=369; unadjusted HR=0.59; 95% CI 0.27, 1.29; p=0.18; adjusted HR=0.53; 95% CI 0.23, 1.23, p=0.14). Adolescents with higher baseline CES-D10 scores showed a significantly stronger effect of CATCH-IT on time-to-event relative to those with lower baseline scores (p=0.04). For example, for a CES-D10 score of 15 (significant sub-syndromal depression), HR=0.20 (95% CI 0.05, 0.77), compared to CES-D10 of 5 (no sub-syndromal depression), HR=1.44 (95% CI, 0.41, 5.03). In both CATCH-IT and HE groups, depression symptoms declined and functional scores increased. CONCLUSIONS AND RELEVANCE: CATCH-IT may be better than HE for preventing depressive episodes for at-risk adolescents with sub-syndromal depression. CATCH-IT may be a scalable approach to prevent depressive episodes in adolescents in primary care.

A Little Effort Can Withstand the Hardship: Fielding an Internet-Based Intervention to Prevent Depression among Urban Racial/Ethnic Minority Adolescents in a Primary Care Setting.

BACKGROUND: This study explored the implementation of Chicago Urban Resiliency Building (CURB), a randomized clinical trial designed as an Internet-based primary care depression prevention intervention for urban African American and Latino adolescents. METHODS: We utilized a mixed methods analysis to explore four aims. First, we estimated the percent of at-risk adolescents that were successfully screened. Second, we examined clinic site factors and performance. Third, primary care providers (n = 10) and clinic staff (n = 18) were surveyed to assess their knowledge and attitudes about the intervention. Fourth, clinic staff (nursing and medical assistant) interviews were analyzed using thematic analysis to gather perspectives of the implementation process. RESULTS: We found that the estimated percent of at-risk adolescents who were successfully screened in each clinic varied widely between clinics with a mean of 14.48%. Daily clinic communication was suggestive of greater successful screening. Feasibility of screening was high for both primary care providers and clinic staff. Clinic staff exit interviews indicated the presence of community barriers that inhibited successful implementation of the intervention. CONCLUSION: This study shares the challenges and successes for depression screening and implementing Internet-based mental health interventions for urban racial/ethnic minority adolescents in primary care settings.

First, Do No Harm: Referring Primary Care Patients with Depression to an Internet Support Group.

BACKGROUND: Internet Support Groups (ISGs) offer people easy access to information regarding depression as well as support from others who are either currently suffering from depression or have previously suffered from depression. The safety and efficacy of ISGs for people with depression have not been thoroughly studied. INTRODUCTION: The safety and helpfulness of a depression ISG were assessed by analyzing pre- and postintervention depressive symptoms, other psychological outcomes, and participant ratings of helpfulness. MATERIALS AND METHODS: Participants were recruited through self-referral from six primary care offices. Participants were given access to a depression ISG and participated in an ISG for 6 weeks. RESULTS: Thirty-four (n = 34) participants enrolled in the study (mean age = 32.53, standard deviation [SD] = 16.10). Depressive symptoms approached significance for decreasing over time and self-efficacy increased over time. No self-harm occurred over the course of the study, but two participants developed self-harm ideation. Ratings of ISG helpfulness were mixed. DISCUSSION: Primary care patients participating in depression ISGs reported few adverse experiences directly related to the ISG. Depressive symptoms and self-efficacy have beneficial findings while ratings of helpfulness were mixed. CONCLUSIONS: Primary care patients can benefit from the use of an ISG. This could be particularly pertinent to people in rural settings where mental health resources are not as available. An ISG offers a low-cost and easily accessible resource for primary care patients with depression.

Proposed model for the cultural adaptation of an Internet-based depression prevention intervention (CATCH-IT) for Arab adolescents.

Background Evidence-based Internet depression prevention intervention programs are not readily available for Arab youth, but may be effective in this group. Cultural adaptation of evidence-based Western psychotherapy is an important step toward better prevention and treatment of depressive illness in the Arab community. Project CATCH-IT is an Internet-based depression prevention intervention tool that is tailored for adolescents and young adults. Methods The PEN-3 theoretical framework was used for the cultural adaptation of Project CATCH-IT for Arab adolescents. First, a narrative review of existing research about depression in Arab nations was performed. Next, expert opinions about applicability and societal values were obtained. This model was then used to suggest relevant changes to the CATCH-IT modules. These modifications were applied to create sample webpages from the culturally adapted version of CATCH-IT for Arab youth. Results The narrative review, expert opinions and resultant PEN-3 analysis suggest that Internet-based depression interventions are effective, private and confidential. To be most effective, religious leaders and fathers should be the stakeholders approached for dissemination and adequate usage of the service. Arab themes, quotes, language and relevant stories must be incorporated. Conclusion This study sets the background for future studies and research for implementation of the Arabic version of CATCH-IT for the prevention of depression. Using the contextual information provided in this paper to make the necessary changes, huge strides can be made in providing cost-effective and accessible Internet-based interventions to Arab youth.

Associations of depression status and hopelessness with breast cancer: A 24-year follow-up study.

This study extended the literature by examining whether three profiles of depression predicted breast cancer status. In 1076 women of the Baltimore Epidemiologic Catchment Area study, depression status and hopelessness were measured at baseline and breast cancer status was ascertained 24 years later. Double depression, but not major depression or dysthymia, was associated with breast cancer. Hopelessness predicted fewer new cases of breast cancer. When double depression and hopelessness were simultaneously entered as predictors, the regression weights of both predictors increased. The role of severe and extended duration depression as well as possible explanations for unexpected findings are discussed.

Prevention of Adolescent Depression in Primary Care: Barriers and Relational Work Solutions.

BACKGROUND AND PURPOSE: Depression affects millions of adolescents in the United States each year. This population may benefit from targeted preventive interventions. We sought to understand the internal factors that affect the ability of healthcare organizations to implement an intervention that involves mental health screening and depression prevention treatment of at-risk adolescents in primary care settings. METHODS: From November 2011 to July 2016 we conducted a study of the implementation of a multisite (N=30) phase 3 randomized clinical trial of an Internet-based depression prevention intervention program (CATCH-IT). We describe the prevalence of internal barriers on the screening and enrollment process by reporting REACH (the proportion of target audience exposed to the intervention). RESULTS: A total of 369 adolescents were randomized into the intervention or control program. Mean REACH values for the study clinics were 0.216 for screening and 0.181 for enrollment to CATCH-IT. Mean REACH enrollment lost due to internal barriers was 0.233. This translated to 4,691 adolescents lost at screening and 2,443 adolescents lost at enrollment due to internal barriers. CONCLUSION: We propose a model of the implementation process that emphasizes the importance of positive relational work that assists in overcoming internal barriers to REACH. We also provide implications for policy and practice.

Effectiveness of a culturally attuned Internet-based depression prevention program for Chinese adolescents: A randomized controlled trial.

BACKGROUND: Depression prevention among adolescents is crucial for reducing the global disease burden. Internet-based depression prevention approaches are found to be effective but they were mostly evaluated in a Western context. Grasping the Opportunity is a Chinese Internet intervention, which was translated and modified from CATCH-IT developed in the West. We aimed to evaluate the effectiveness of Grasp the Opportunity in reducing depressive symptoms in Chinese adolescents. METHODS: In this randomized controlled trial, Chinese adolescents aged 13 to 17 years with mild-to-moderate depressive symptoms were recruited from three secondary schools in Hong Kong. The participants (n = 257) were randomly assigned to receive either intervention or attention control. The primary outcome was the improvement in depressive symptoms according to the revised Center for Epidemiologic Studies Depression Scale (CESD-R) at the 12-month follow-up. Analyses were performed using intention to treat (ITT). RESULTS: The participants were randomly assigned to receive the intervention (n = 130) or attention control (n = 127). Follow-up data were obtained from 250 (97%) participants. Only 26 (10%) participants completed the intervention. Compared to the attention control, Grasp the Opportunity led to reductions in depressive symptoms at the 12-month follow-up with a medium effect size using ITT analysis (mean difference 2.6, 95% CI 0.59-5.55, effect size d = 0.36). CONCLUSIONS: Grasp the Opportunity is effective in reducing depressive symptoms in Chinese adolescents over a long follow-up period. Poor completion rate is the major challenge in the study.

RANDOMIZED CLINICAL TRIAL OF AN INTERNET-BASED INTERVENTION TO PREVENT ADOLESCENT DEPRESSION IN A PRIMARY CARE SETTING (CATCH-IT): 2.5-YEAR OUTCOMES.

We developed and tested two primary care based approaches for the early identification and prevention of depressive disorders in adolescents. We conducted a randomized controlled trial originally intended to compare Brief Advice (BA) + Internet intervention with Motivational Interviewing (MI) + Internet intervention in primary care for adolescents experiencing persistent subthreshold depression (Project CATCH-IT). This is an exploratory long-term 2.5 year follow-up study of a phase II study comparing pre/post outcomes and potential moderators of outcomes. Participants (n=44) in the entire cohort maintained from baseline and continued to reduce depressive symptoms and percentage of subsyndromal depression. Greater motivation for depression prevention and lower ratings of self-efficacy at baseline were associated with greater declines in depression symptoms. These results suggest adolescents can be followed-up after Internet studies and there may be evidence of sustained reductions in depressed mood. The CATCH-IT model offers the possibility of a long term effect, but these results are limited by the small sample size and pre-post design. A large scale randomized clinical trial of the intervention is currently in progress.

An internet-based adolescent depression preventive intervention: study protocol for a randomized control trial.

BACKGROUND: The high prevalence of major depressive disorder in adolescents and the low rate of successful treatment highlight a pressing need for accessible, affordable adolescent depression prevention programs. The Internet offers opportunities to provide adolescents with high quality, evidence-based programs without burdening or creating new care delivery systems. Internet-based interventions hold promise, but further research is needed to explore the efficacy of these approaches and ways of integrating emerging technologies for behavioral health into the primary care system. METHODS/DESIGN: We developed a primary care Internet-based depression prevention intervention, Competent Adulthood Transition with Cognitive Behavioral Humanistic and Interpersonal Training (CATCH-IT), to evaluate a self-guided, online approach to depression prevention and are conducting a randomized clinical trial comparing CATCH-IT to a general health education Internet intervention. This article documents the research framework and randomized clinical trial design used to evaluate CATCH-IT for adolescents, in order to inform future work in Internet-based adolescent prevention programs. The rationale for this trial is introduced, the current status of the study is reviewed, and potential implications and future directions are discussed. DISCUSSION: The current protocol represents the only current, systematic approach to connecting at-risk youth with self-directed depression prevention programs in a medical setting. This trial undertakes the complex public health task of identifying at-risk individuals through mass screening of the general primary care population, rather than solely relying on volunteers recruited over the Internet, and the trial design provides measures of both symptomatic and diagnostic clinical outcomes. At the present time, we have enrolled N = 234 adolescents/expected 400 and N = 186 parents/expected 400 in this trial, from N = 6 major health systems. The protocol described here provides a model for a new generation of interventions that blend substantial computer-based instruction with human contact to intervene to prevent mental disorders such as depression. Because of the potential for broad generalizability of this model, the results of this study are important, as they will help develop the guidelines for preventive interventions with youth at-risk for the development of depressive and other mental disorders. CLINICAL TRIAL REGISTRY: NCT01893749 date 6 May 2012.

Development of a technology-based behavioral vaccine to prevent adolescent depression: A health system integration model.

Efforts to prevent depression have become a key health system priority. Currently, there is a high prevalence of depression among adolescents, and treatment has become costly due to the recurrence patterns of the illness, impairment among patients, and the complex factors needed for a treatment to be effective. Primary care may be the optimal location to identify those at risk by offering an Internet-based preventive intervention to reduce costs and improve outcomes. Few practical interventions have been developed. The models for Internet intervention development that have been put forward focus primarily on the Internet component rather than how the program fits within a broader context. This paper describes the conceptualization for developing technology based preventive models for primary care by integrating the components within a behavioral vaccine framework. CATCH-IT (Competent Adulthood Transition with Cognitive-behavioral, Humanistic and Interpersonal Training) has been developed and successfully implemented within various health systems over a period of 14 years among adolescents and young adults aged 13-24.

Understanding adolescent response to a technology-based depression prevention program.

Guided by the Behavioral Vaccine Theory of prevention, this study uses a no-control group design to examine intervention variables that predict favorable changes in depressive symptoms at 6- to 8-week follow-up in at-risk adolescents who participated in a primary care, Internet-based prevention program. Participants included 83 adolescents from primary care settings ages 14 to 21 (M = 17.5, SD = 2.04), 56.2% female, with 41% non-White. Participants completed self-report measures, met with a physician, and then completed a 14-module Internet intervention targeting the prevention of depression. Linear regression models indicated that several intervention factors (duration on website in days, the strength of the relationship with the physician, perceptions of ease of use, and the perceived relevance of the material presented) were significantly associated with greater reductions in depressive symptoms from baseline to follow-up. Automatic negative thoughts significantly mediated the relation between change in depressive symptoms scores and both duration of use and physician relationship. Several intervention variables predicted favorable changes in depressive symptom scores among adolescents who participated in an Internet-based prevention program, and the strength of two of these variables was mediated by automatic negative thoughts. These findings support the importance of cognitive factors in preventing adolescent depression and suggest that modifiable aspects of technology-based intervention experience and relationships should be considered in optimizing intervention design.
