Item Determinants of access to health care for depression in 49 countries: A multilevel analysis(2018) Araya, Ricardo; Zitko, Pedro; Markkula, Niina; Rai, Dheeraj; Jones, KelvynBackground: The relative importance of individual and country-level factors influencing access to diagnosis and treatment for depression across the world is fairly unknown. Methods: We analysed cross-national data from the WHO World Health Surveys. Depression diagnosis and access to health care were ascertained using a structured interview. Logistic Bayesian Multilevel analyses were performed to establish individual and country level factors associated with: (1) receiving a diagnosis and (2) accessing treatment for depression if a diagnosis was ascertained. Results: The sample included 7870 individuals from 49 countries who met ICD-10 criteria for depressive episode in the past 12 months. A third (32%) of these individuals had ever been diagnosed with depression in their lifetime. Among those diagnosed with depression, 66% reported to have ever received treatment for depression. Although individual factors were more important determinants of access to treatment for depression, countrylevel factors explained 27.6% of the variance in access to diagnosis and 24.1% in access to treatment. Access to treatment for depression improved with increasing country income. Female gender, better education, the presence of physical co-morbidity, more material assets, and living in urban areas were individual level determinants of better access. Limitations: Data on other contextual factors was not available. Unmet need was likely underestimated, since only lifetime treatment data was available. Conclusion: This study highlights major inequalities in access to a diagnosis and treatment of depression. Unlike the prevalence of depression, where contextual factors have shown to have less importance, a significant proportion of the variance in access to depression care was explained by country-level income.Item The Impact of Universal Health Care Programmes on Improving ‘Realized Access’ to Care for Depression in Chile(2018) Araya, Ricardo; Zitko, Pedro; Markkula, NiinaUniversal health care programmes have the potential to reduce treatment gaps. We explored the potential impact of an equityoriented universal health care programme on access to care for depression, hypertension and diabetes using data from two nationally representative health surveys in Chile. The likelihood a depressed individual had accessed health care appears to have increased significantly after the programme was introduced whereas those for hypertension and diabetes remained unchanged. Depressed women seem to have benefited mostly from the programme. Universal health care programmes for depression could substantially increase coverage and reduce inequities in access to health care in middle-income countriesItem The Unplugged program in Chile (“Yo Sé Lo Que Quiero”) for substance use prevention among early adolescents: study protocol for a randomized controlled trial(2022) Gaete, Jorge; Ramírez, Saray; Gana, Sofía; Valenzuela, Daniela; Araya, RicardoBackground Substance use is among the main contributors to disease among children and adolescents in the Americas region. The call for effective prevention of substance use among adolescents has resulted in numerous school-based programs, and particularly the Unplugged program has been proved to be successful in reducing the prevalence of different substances in seven European countries. The purpose of this study is to test the effectiveness of the Unplugged program in Chile (“Yo Sé Lo Que Quiero”). Methods This is a cluster randomized controlled trial, parallel-group type, where “Yo Sé Lo Que Quiero” is compared to standard school preventive curricula in control schools. A total of 70 schools and 8400 adolescents are expected to be randomized with 1:1 allocation. During formative work, the Unplugged program was culturally adapted to Chile, and the instrument to assess the primary and secondary outcomes was validated. The effectiveness of this program will be assessed using the European Drug Addiction Prevention Trial Questionnaire (EU-Dap), measuring substance use prevalence and risk and protective factors in baseline, post-intervention, and four months after the end of the intervention. Discussion The proposed study will be the first to test the effectiveness of a school-based substance use prevention program in Chile in a cluster randomized control trial and the first study evaluating the Unplugged program in Spanish-speaking Latin America. A model for disseminating the Unplugged program inside Europe already exists and has been implemented successfully in several countries. Thus, if the effects of the program are positive, wide implementation in Chile and Latin American countries is possible soon.
