ABSTRACT
Background: Few existing evidence-based parent interventions (EBPIs) for prevention and treatment of child and youth mental health disorders are implemented in low-middle-income countries. This study aimed to translate and confirm the factor structure of the Evidence-Based Practice Attitude Scale (EBPAS-15) survey in Brazilian Portuguese with the goal of examining providers' perspective about EBPIs. Methods: We translated and back translated the EBPAS-15 from English to Brazilian Portuguese. Participants were recruited via snowball sampling and data were collected using an online survey from July of 2018 through January of 2020. A confirmatory factor analysis was conducted to determine if the scale retained its original structure. Open-ended questions about providers' perspectives of their own clinical practice were coded using the Theoretical Domains Framework (TDF). Analyses included data from 362 clinicians (318 women, 41 men) from 20 of the 27 states of Brazil. Participants on average were 26.7 years old, held specialist degrees in the field of psychology, actively worked as therapists, and practiced in private clinics. Results: The translation of the EBPAS to Brazilian Portuguese retained the same four-factor structure as the English version except for dropping one item from the Divergence domain. When asked about the challenges in their practices, providers generally referred to parents as clients with little skills to discipline their children and lacking knowledge about child development. Discussion: The Brazilian version of the EBPAS-15 is promising, but future research should consider using quantitative data alongside qualitative information to better understand providers' attitudes about evidence-based interventions to inform implementation efforts. Trial registration: N/A.
ABSTRACT
Background: Sickle Cell Disease (SCD) is a progressive genetic disease that causes organ damage and reduces longevity. Hydroxyurea is an underutilized evidence-based medication that reduces complications and improves survival in SCD. In a multi-site clinical trial, part of the NIH-funded Sickle Cell Disease Implementation Consortium (SCDIC), we evaluate the implementation of a multi-level and multi-component mobile health (mHealth) patient and provider intervention to target the determinants and context of low hydroxyurea use. Given the complexity of the intervention and contextual variability in its implementation, we combined different behavioral and implementation theories, models, and frameworks to facilitate the evaluation of the intervention implementation. In this report, we describe engagement with stakeholders, planning of the implementation process, and final analytical plan to evaluate the implementation outcomes. Methods: During 19 meetings, a 16-member multidisciplinary SCDIC implementation team created, conceived, and implemented a project that utilized Intervention Mapping to guide designing an intervention and its evaluation plan. The process included five steps: (1) needs assessment of low hydroxyurea utilization, (2) conceptual framework development, (3) intervention design process, (4) selection of models and frameworks, and (5) designing evaluation of the intervention implementation. Results: Behavioral theories guided the needs assessment and the design of the multi-level mHealth intervention. In designing the evaluation approach, we combined two implementation frameworks to best account for the contextual complexity at the organizational, provider, and patient levels: (1) the Consolidated Framework for Implementation Research (CFIR) that details barriers and facilitators to implementing the mHealth intervention at multiple levels (users, organization, intervention characteristics, broader community), and (2) the Technology Acceptance Model (TAM), a conceptual model specific for explaining the intent to use new information technology (including mHealth). The Reach Effectiveness Adoption Implementation and Maintenance (RE-AIM) framework was used to measure the outcomes. Discussion: Our research project can serve as a case study of a potential approach to combining different models/frameworks to help organize and plan the evaluation of interventions to increase medication adherence. The description of our process may serve as a blueprint for future studies developing and testing new strategies to foster evidence-based treatments for individuals living with SCD.
ABSTRACT
The insect juvenile hormone receptor is a basic helix-loop-helix (bHLH), Per-Arnt-Sim (PAS) domain protein, a novel type of hormone receptor. In higher flies like Drosophila, the ancestral receptor germ cell-expressed (gce) gene has duplicated to yield the paralog Methoprene-tolerant (Met). These paralogous receptors share redundant function during development but play unique roles in adults. Some aspects of JH function apparently require one receptor or the other. To provide a foundation for studying JH receptor function, we have recapitulated endogenous JH receptor expression with single cell resolution. Using Bacteria Artificial Chromosome (BAC) recombineering and a transgenic knock-in, we have generated a spatiotemporal expressional atlas of Met and gce throughout development. We demonstrate JH receptor expression in known JH target tissues, in which temporal expression corresponds with periods of hormone sensitivity. Larval expression largely supports the notion of functional redundancy. Furthermore, we provide the neuroanatomical distribution of JH receptors in both the larval and adult central nervous system, which will serve as a platform for future studies regarding JH action on insect behavior.
