24-Month Outcomes of Primary Care Web-Based Depression Prevention Intervention in Adolescents: Randomized Clinical Trial.

BACKGROUND: Adolescent depression carries a high burden of disease worldwide, but access to care for this population is limited. Prevention is one solution to curtail the negative consequences of adolescent depression. Internet interventions to prevent adolescent depression can overcome barriers to access, but few studies examine long-term outcomes. OBJECTIVE: This study compares CATCH-IT (Competent Adulthood Transition with Cognitive Behavioral Humanistic and Interpersonal Training), an internet-based intervention, to a general health education active control for depression onset at 12 and 24 months in adolescents presenting to primary care settings. METHODS: A 2-site randomized trial, blinded to the principal investigators and assessors, was conducted comparing Competent Adulthood Transition with Cognitive Behavioral Humanistic and Interpersonal Training to health education to prevent depressive episodes in 369 adolescents (193 youths were randomly assigned to Competent Adulthood Transition with Cognitive Behavioral Humanistic and Interpersonal Training and 176 to health education) with subthreshold depressive symptoms or prior depressive episodes. Participants were recruited from primary care settings in the United States. The primary outcome was the occurrence of a depressive episode, determined by the Depression Symptom Rating. The secondary outcome was functioning, measured by the Global Assessment Scale. RESULTS: In intention-to-treat analyses, the adjusted hazard ratio favoring Competent Adulthood Transition with Cognitive Behavioral Humanistic and Interpersonal Training for first depressive episode was not statistically significant at 12 months (hazard ratio 0.77, 95% CI 0.42-1.40, P=.39) and 24 months (hazard ratio 0.87, 95% CI 0.52-1.47, P=.61). Competent Adulthood Transition with Cognitive Behavioral Humanistic and Interpersonal Training provided preventive benefit for first depressive episode for those with mild hopelessness or at least moderate paternal monitoring at baseline. Global Assessment Scale scores improved comparably in both groups (intention-to-treat). CONCLUSIONS: A technology-based intervention for adolescent depression prevention implemented in primary care did not have additional benefit at 12 or 24 months. Further research is necessary to determine whether internet interventions have long-term benefit. TRIAL REGISTRATION: ClinicalTrials.gov NCT01893749; http://clinicaltrials.gov/ct2/show/NCT01893749.

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.

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.

Internal versus external motivation in referral of primary care patients with depression to an internet support group: randomized controlled trial.

BACKGROUND: Depressive disorders and symptoms affect more than one-third of primary care patients, many of whom do not receive or do not complete treatment. Internet-based social support from peers could sustain depression treatment engagement and adherence. We do not know whether primary care patients will accept referral to such websites nor do we know which methods of referral would be most effective. OBJECTIVE: We conducted a randomized clinical trial to determine whether (1) a simple generic referral card (control), (2) a patient-oriented brochure that provided examples of online postings and experience (internal motivation), or (3) a physician letter of recommendation (external motivation) would generate the greatest participation in a primary care Internet depression treatment support portal focused around an Internet support group (ISG). METHODS: We used 3 offline methods to identify potential participants who had not used an ISG in the past 6 months. Eligibility was determined in part by a brief structured psychiatric interview based on the Patient Health Questionnaire-9 (PHQ-9). After consent and enrollment, participants were randomly assigned to 1 of 3 groups (control, internal motivation, or external motivation). We constructed a portal to connect primary care patients to both fact-based information and an established ISG (Psycho-Babble). The ISG allowed participants to view messages and then decide if they actually wished to register there. Participation in the portal and the ISG was assessed via automated activity tracking. RESULTS: Fifty participants were assigned to the 3 groups: a motivation-neutral control group (n=18), an internal motivation group (n=19), and an external motivation group (n=13). Of these participants, 31 (62%) visited the portal; 27 (54%) visited the ISG itself. The internal motivation group showed significantly greater participation than the control group on several measures. The external motivation group spent significantly less time logged onto the portal than the control group. The internal motivation group showed significantly greater participation than the external motivation group on several measures. CONCLUSIONS: Referral of primary care patients with depressive disorders and symptoms to an ISG is feasible even if they have never previously used one. This may best be accomplished by enhancing their internal motivation.

Economic analysis of an internet-based depression prevention intervention.

BACKGROUND: The transition through adolescence places adolescents at increased risk of depression, yet care-seeking in this population is low, and treatment is often ineffective. In response, we developed an Internet-based depression prevention intervention (CATCH-IT) targeting at-risk adolescents. AIMS OF THE STUDY: We explore CATCH-IT program costs, especially safety costs, in the context of an Accountable Care Organization as well as the perceived value of the Internet program. METHODS: Total and per-patient costs of development were calculated using an assumed cohort of a 5,000-patient Accountable Care Organization. Total and per-patient costs of implementation were calculated from grant data and the Medicare Resource-Based Relative Value Scale (RBRVS) and were compared to the willingness-to-pay for CATCH-IT and to the cost of current treatment options. The cost effectiveness of the safety protocol was assessed using the number of safety calls placed and the percentage of patients receiving at least one safety call. The willingness-to-pay for CATCH-IT, a measure of its perceived value, was assessed using post-study questionnaires and was compared to the development cost for a break-even point. RESULTS: We found the total cost of developing the intervention to be USD 138,683.03. Of the total, 54% was devoted to content development with per patient cost of USD 27.74. The total cost of implementation was found to be USD 49,592.25, with per patient cost of USD 597.50. Safety costs accounted for 35% of the total cost of implementation. For comparison, the cost of a 15-session group cognitive behavioral therapy (CBT) intervention aimed at at-risk adolescents was USD 1,632 per patient. Safety calls were successfully placed to 96.4% of the study participants. The cost per call was USD 40.51 with a cost per participant of USD 197.99. The willingness-to-pay for the Internet portion of CATCH-IT had a median of USD 40. The break-even point to offset the cost of development was 3,468 individuals. DISCUSSION AND LIMITATIONS: Developing Internet-based interventions like CATCH-IT appears economically viable in the context of an Accountable Care Organization. Furthermore, while the cost of implementing an effective safety protocol is proportionally high for this intervention, CATCH-IT is still significantly cheaper to implement than current treatment options. Limitations of this research included diminished participation in follow-up surveys assessing willingness-to-pay. IMPLICATIONS FOR HEALTH CARE PROVISION AND USE AND HEALTH POLICIES: This research emphasizes that preventive interventions have the potential to be cheaper to implement than treatment protocols, even before taking into account lost productivity due to illness. Research such as this business application analysis of the CATCH-IT program highlights the importance of supporting preventive medical interventions as the healthcare system already does for treatment interventions. IMPLICATIONS FOR FURTHER RESEARCH: This research is the first to analyze the economic costs of an Internet-based intervention. Further research into the costs and outcomes of such interventions is certainly warranted before they are widely adopted. Furthermore, more research regarding the safety of Internet-based programs will likely need to be conducted before they are broadly accepted.

Attitudes toward depression among a sample of Muslim adolescents in the Midwestern United States.

BACKGROUND: Little is known about how Muslim youth in non-Muslim countries perceive depression and its treatment and prevention. OBJECTIVE: We investigated the barriers and suggest treatment models for depressive disorders in Muslim adolescents and young adults residing in the United States. METHODS: We conducted a thorough literature review to identify previous study on the beliefs of American Muslim adolescents about depression and its treatment. We identified the gaps and developed a survey to ascertain this information from American Muslim adolescents. RESULTS: The survey was administered to a convenience sample of 125 Muslim subjects (60.0% males) aged 14-21 years. The sample was ethnically diverse with Pakistani (44.8%) encompassing the majority of the sample. Most responders believed that recitation from the Koran relieves mental distress. Multiple linear regression analysis revealed that those who reported strong emotional support from parents or a greater acceptance of taking depression medication prescribed from a physician were more likely to accept a physician's diagnosis, whereas believing in prayer to heal depression was associated with a lower likelihood of the same. Youth were accepting of Internet and preventive approaches. CONCLUSION: Planning of culturally sensitive mental health services is useful to accommodate the needs of Muslim youth served by primary care physicians and mental health practitioners in the United States. Muslim adolescents tend to be more traditional with family, social, and religious values. This value system plays an important role in their likelihood of seeking and accepting professional help for depression.

A Two-Way Interactive Text Messaging Application for Low-Income Patients with Chronic Medical Conditions: Design-Thinking Development Approach.

BACKGROUND: Two-way interactive text messaging between patient and community health workers (CHWs) through mobile phone SMS (short message service) text messaging is a form of digital health that can potentially enhance patient engagement in young adults and families that have a child with chronic medical conditions such as diabetes mellitus, sickle cell disease, and asthma. These patients have complex needs, and a user-centered way can be useful for designing a tool to address their needs. OBJECTIVE: The aim of this study was to utilize the user-centered approach of design thinking to develop a two-way interactive communication SMS text messaging tool for communication between patients or caregivers and CHWs. METHODS: We applied a design thinking methodology for development of the SMS text messaging tool. We collected qualitative data from 127 patients/caregivers and 13 CHWs, health care professionals, and experts. In total, 4 iterative phases were used to design the final prototype. RESULTS: The design thinking process led to the final SMS text messaging tool that was transformed from a one-dimensional, template-driven prototype (phases 1 and 2) into a dynamic, interactive, and individually tailored tool (phases 3 and 4). The individualized components consider social factors that influence patients' ability to engage such as transportation issues and appointment reminders. SMS text messaging components also include operational factors to support staff such as patient contact lists, SMS text messaging templates, and technology chat support. CONCLUSIONS: Design thinking can develop a tool to meet the engagement needs of patients with complex health care needs and be user-friendly for health care staff.

Impact of an online depression prevention intervention on suicide risk factors for adolescents and young adults.

BACKGROUND: Adolescent death by suicide is an emergent health crisis in the United States of America. Although many suicide prevention programs have been created to address suicide in this population, rates continue to increase. Online interventions can disseminate treatments world-wide and reach large numbers of users. Thus, the purpose of the present study was to determine the effects of CATCH-IT, an Internet-based depression prevention intervention on risk factors for suicide (i.e., suicidal ideation, hopelessness, low self-esteem and social isolation). METHODS: A total of 83 participants aged 14-21 years [mean =17.5; standard deviation (SD) =2.04] consented to take part in the intervention study. RESULTS: Results indicated that suicidal ideation decreased from baseline to post-intervention. For those who completed the entire CATCH-IT program, the effect size was moderate (d =0.60, P<0.05). For those who partially completed the program the effect size was small (d =0.22, P<0.05). Interestingly, scales measuring hopelessness and social isolation were not associated with changes in suicidal ideation. CONCLUSIONS: The findings provide initial evidence that online depression prevention programs could be related to decreased suicidal ideation, and that those who complete the entire program may benefit more than those who complete only a part of CATCH-IT.

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.

"Why Should I Tell My Business?": An Emerging Theory of Coping and Disclosure in Teens.

Disclosing predepression feelings of sadness is difficult for teens. Primary care providers are a potential avenue for teens to disclose these feelings and a bridge to mental health care before becoming more seriously ill. To explore how to more effectively recruit teens into a primary care-based, online depression prevention study, we held 5 focus groups with African American and Latino teens (n = 43) from a large Midwestern city. We conducted constant comparative analysis of the data and a theoretical conceptualization of coping and disclosure emerged. Our analysis revealed an internal coping continuum in reaction to sadness and pivotal elements of trust and judgment that either lead teens to disclose or not disclose these feelings. The teens' perspectives show the necessary characteristics of a relationship and comfortable community and virtual settings that can best allow for teens to take the step of disclosing to receive mental health care services.

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.

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.

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.

Randomized Clinical Trial of a Primary Care Internet-based Intervention to Prevent Adolescent Depression: One-year Outcomes.

OBJECTIVE: We developed a primary care/Internet-based intervention for adolescents at risk for depression (CATCH-IT, Competent Adulthood Transition with Cognitive-behavioral, Humanistic and Interpersonal Training). This phase II clinical trial compares two forms of primary care provider (PCP) engagement (motivational interview [MI] and brief advice [BA]) for adolescents using the Internet program. METHOD: ADOLESCENTS SCREENING POSITIVE FOR DEPRESSION WERE RECRUITED FROM PRIMARY CARE PRACTICES AND RANDOMLY ASSIGNED TO A VERSION OF THE INTERVENTION: PCP MI + Internet program or PCP BA + Internet program. Between-group and within-group comparisons were conducted on depressive disorder outcome measures at baseline and one-year post-enrollment. Regression analyses examined factors predicting declines in depressed mood. RESULTS: Both groups demonstrated significant within-group decreases in depressed mood, loneliness, and self-harm ideation. While no between-group differences were noted in depressed mood or depressive disorder measures at one-year, fewer participants in the MI group had experienced a depressive episode. Greater participant automatic negative thoughts and more favorable ratings of a component of the Internet-based training experience predicted declines in depressed mood at one-year. CONCLUSIONS: A primary care/Internet-based intervention for depression prevention demonstrated sustained reductions in depressed mood, and, when coupled with motivational interviewing, reduction in the likelihood of being diagnosed with a depressive episode. This tool may help extend the services at the disposal of a primary care provider and can provide a bridge for adolescents at risk for depression prior to referral to mental health specialists.

OBJECTIF: Nous avons mis au point une intervention de soins de première ligne sur Internet pour les adolescents à risque de dépression (CATCH-IT, transition compétente à l'âge adulte par une formation cognitivo-comportementale, humaniste et interpersonnelle). Cette phase II de l'essai clinique compare deux formes d'interaction des prestataires de soins de première ligne (PSPL) (entrevue motivationnelle [EM] et brefs conseils [BC]) avec les adolescents qui utilisent le programme en ligne. MÉTHODE: Les adolescents chez qui une dépression a été dépistée ont été recrutés dans des pratiques de soins de première ligne et affectés au hasard à une version de l'intervention: EM PSPL + programme Internet ou BC PSPL + programme Internet. Les comparaisons entre groupes et au sein des groupes ont été menées sur les mesures de résultat du trouble dépressif, au départ et un an après l'inscription. Des analyses de régression ont examiné les facteurs prédisant les baisses de l'humeur dépressive. RÉSULTATS: Les deux groupes ont démontré des baisses significatives au sein du groupe de l'humeur dépressive, de la solitude, et de l'idéation d'automutilation. Bien qu'aucune différence des mesures de l'humeur dépressive ou du trouble dépressif n'ait été notée entre les groupes à un an, moins de participants du groupe EM ont connu un épisode dépressif. Les pensées négatives automatiques accrues des participants et les cotations plus favorables d'un élément de l'expérience de formation sur Internet prédisaient des baisses de l'humeur dépressive à un an. CONCLUSIONS: Une intervention de soins de première ligne sur Internet pour prévenir la dépression a démontré des baisses soutenues de l'humeur dépressive et, lorsque jumelée à la technique d'entrevue motivationnelle, une probabilité moindre de recevoir un diagnostic d'épisode dépressif a été observée. Cet instrument peut contribuer à étendre les services qui sont à la disposition des prestataires de soins de première ligne, et peut constituer un relais pour les adolescents à risque de dépression, avant de les adresser aux spécialistes de la santé mentale.

Pilot Study of Implementation of an Internet-Based Depression Prevention Intervention (CATCH-IT) for Adolescents in 12 US Primary Care Practices: Clinical and Management/Organizational Behavioral Perspectives.

OBJECTIVE: To explore the implementation of CATCH-IT (Competent Adulthood Transition with Cognitive-behavioral Humanistic and Interpersonal Training), an Internet-based depression intervention program in 12 primary care sites, occurring as part of a randomized clinical trial comparing 2 versions of the intervention (motivational interview + Internet program versus brief advice + Internet program) in 83 adolescents aged 14 to 21 years recruited from February 1, 2007, to November 31, 2007. METHOD: The CATCH-IT intervention model consists of primary care screening to assess risk, a primary care physician interview to encourage participation, and 14 online modules of Internet training to teach adolescents how to reduce behaviors that increase vulnerability to depressive disorders. Specifically, we evaluated this program from both a management/organizational behavioral perspective (provider attitudes and demonstrated competence) and a clinical outcomes perspective (depressed mood scores) using the RE-AIM model (Reach, Efficacy, Adoption, Implementation, and Maintenance of the intervention). RESULTS: While results varied by clinic, overall, clinics demonstrated satisfactory reach, efficacy, adoption, implementation, and maintenance of the CATCH-IT depression prevention program. Measures of program implementation and management predicted clinical outcomes at practices in exploratory analyses. CONCLUSION: Multidisciplinary approaches may be essential to evaluating the impact of complex interventions to prevent depression in community settings. Primary care physicians and nurses can use Internet-based programs to create a feasible and cost-effective model for the prevention of mental disorders in adolescents in primary care settings.
