Reasons for validating evaluation instruments

Development and establishment of new APN roles is a complex process2 that has resulted from a wide variety of reasons,3 although a key component is role definition, competency map delineation and role evaluation.4It is noticeable both the heterogeneity of definitions, methodological difficulties through the different attempts at designing competency assessment methods in nursing,5 8 plus the difficulties in defining competence attributes.9 Reviews regarding the development of competencies in nursing do exist but none of them is specifically devoted to advanced practice.10–12The progressive worldwide implementation of these advanced roles has led to a growing development of standards of practice and competency maps,13 but with many different conceptual approaches.14 Some recent efforts have been proposed to establish competency frameworks as a background to develop new APN roles15 16 or reviewing existing ones,17 essentially based on competency mapping and role delineation.18 Consequently, this new scenario needs to validate specific tools for APN competency assessment.Nevertheless, in certain cases, existing instruments are restricted to a particular context like the Scandinavian19 or the Japanese.20 Other instruments address very specific roles,21 24 In the tools analysed, inconsistency in the validation process was detected in order to justify a new instrument development approach.There are numerous statistical tests and measures to assess the validity of quantitative instruments, which generally involves pilot testing.The remainder of this discussion focuses on external validity and content validity. Establishing eternal validity for an instrument, then, follows directly from sampling.At the same time, creating new tools requires expertise in measurement and instrument design. When considering the use of an instrument, keep in mind the following: These sites provide access to tools and instruments useful for evaluating the wide range of outcomes addressed by informal STEM education experiences.Research and Evaluation Instruments on Informal Science.org: This section of Informal allows users to search a collection of evaluation reports, articles, and other resources that include evaluation instruments and tools.

The progressive spread of Advanced Practice Nursing (APN) worldwide1 has generated a whole range of approaches in the creation and development of this nurse role, not free of controversy and conceptual ambiguity.Objective To describe the development and clinimetric validation of the Advanced Practice Nursing Competency Assessment Instrument (APNCAI) through several evidence sources about reliability and validity in the Spanish context.Design and setting APNCAI development was based on a multisequential and systematic process: literature review, instrument content consensus through qualitative Delphi method approach (a panel of 51 Advanced Practice in Nursing –APN– experts was selected) and the clinimetric validation process based on a sample of 600 nurses from the Balearic Islands public healthcare setting.It is rare, if nearly impossible, that an instrument be 100% valid, so validity is generally measured in degrees.As a process, validation involves collecting and analyzing data to assess the accuracy of an instrument.
