Purposeful Sampling for Qualitative Data Collection and Analysis in Mixed Method Implementation Research | Administration and Policy in Mental Health and Mental Health Services Research
Lawrence A Palinkas, Sarah M Horwitz, Carla A Green, Jennifer P Wisdom, Naihua Duan, Kimberly Hoagwood
2013 Purposeful sampling is widely used in qualitative research for the identification and selection of information-rich cases related to the phenomenon of interest. Although there are several different purposeful sampling strategies, criterion sampling appears to be used most commonly in implementation research. However, combining sampling strategies may be more appropriate to the aims of implementation research and more consistent with recent developments in quantitative methods...

2012 Decades of randomized controlled trials have produced separate evidence-based treatments for depression, anxiety, and conduct problems in youth, but these treatments are not often used in clinical practice, and they produce mixed results in trials with the comorbid, complex youths seen in practice. An integrative, modular redesign may help.
Mixed Method Designs in Implementation Research | Administration and Policy in Mental Health and Mental Health Services Research
Lawrence A Palinkas, Gregory A Aarons, Sarah Horwitz, Patricia Chamberlain, Michael Hurlburt, John Landsverk
2011 This paper describes the application of mixed method designs in implementation research in 22 mental health services research studies published in peer-reviewed journals over the last 5 years. Our analyses revealed 7 different structural arrangements of qualitative and quantitative methods, 5 different functions of mixed methods, and 3 different ways of linking quantitative and qualitative data together. Complexity of design was associated with number of aims or objectives, study context, and phase of implementation examined. The findings provide suggestions for the use of mixed method designs in implementation research.

2008 Childhood obesity with its associated metabolic complications is emerging as a major global health challenge of the 21st century. Despite efforts by government and public health officials, researchers, health care providers, and the media to bring attention to this growing health problem, the number of overweight and obese youth continues to increase. Approximately 110 million children worldwide are now classified as overweight or obese.
Implementation of Evidence-based Practice in Child Welfare: Service Provider Perspectives | Administration and Policy in Mental Health and Mental Health Services Research
Gregory A Aarons, Lawrence A Palinkas
2007 Implementation of evidence-based practices (EBP) in child welfare is a complex process that is often fraught with unanticipated events, conflicts, and resolutions. To some extent, the nature of the process, problems, and solutions may be dependent on the perspectives and experiences of a given stakeholder group. In order to better understand the implementation process in the child-welfare system, we interviewed comprehensive home-based services (CHBS) case managers who were actively engaged in implementing an EBP to reduce child neglect in a state youth services system. Six primary factors were identified as critical determinants of EBP implementation: (1) Acceptability of the EBP to the caseworker and to the family, (2) Suitability of the EBP to the needs of the family, (3) Caseworker motivations for using the EBP, (4) Experiences with being trained in the EBP, (5) Extent of organizational support for EBP implementation, and (6) Impact of EBP on process and outcome of services. These factors reflect two broader themes of attitudes toward or assessments of the EBP itself and experiences with learning and delivering the EBP. Eventual implementation is viewed as the consequence of perseverance, experience, and flexibility.
