شیوه های مبتنی بر شواهد در زمینه معلولیت ذهنی و رشدی: رویکرد اجماع بین المللی

As evidence-based practices become increasingly advocated for and used in the human services field it is important to integrate issues raised by three perspectives on evidence: empirical–analytical, phenomenological–existential, and post-structural. This article presents and discusses an evidence-based conceptual model and measurement framework that integrates these three perspectives and results in: multiple perspectives on evidence-based practices that involve the individual, the organization, and society; and multiple interpretation guidelines related to the quality, robustness, and relevance of the evidence. The article concludes with a discussion of five issues that need to be addressed in the future conceptualization, measurement and application of evidence-based practices. These five are the need to: expand the concepts of internal and external validity, approach evidence-based practices from a systems perspective, integrate the various perspectives regarding evidence-based practices, develop and evaluate evidence-based practices within the context of best practices, and develop a set of guidelines related to the translation of evidence into practice.
