The GRADE-CERQual (Confidence in Evidence from Reviews of Qualitative research) approach has been developed by the GRADE (Grading of Recommendations Assessment, Development and Evaluation) Working ...Group. The approach has been developed to support the use of findings from qualitative evidence syntheses in decision making, including guideline development and policy formulation. CERQual includes four components for assessing how much confidence to place in findings from reviews of qualitative research (also referred to as qualitative evidence syntheses): (1) methodological limitations, (2) coherence, (3) adequacy of data and (4) relevance. This paper is part of a series providing guidance on how to apply CERQual and focuses on making an overall assessment of confidence in a review finding and creating a CERQual Evidence Profile and a CERQual Summary of Qualitative Findings table.
We developed this guidance by examining the methods used by other GRADE approaches, gathering feedback from relevant research communities and developing consensus through project group meetings. We then piloted the guidance on several qualitative evidence syntheses before agreeing on the approach.
Confidence in the evidence is an assessment of the extent to which a review finding is a reasonable representation of the phenomenon of interest. Creating a summary of each review finding and deciding whether or not CERQual should be used are important steps prior to assessing confidence. Confidence should be assessed for each review finding individually, based on the judgements made for each of the four CERQual components. Four levels are used to describe the overall assessment of confidence: high, moderate, low or very low. The overall CERQual assessment for each review finding should be explained in a CERQual Evidence Profile and Summary of Qualitative Findings table.
Structuring and summarising review findings, assessing confidence in those findings using CERQual and creating a CERQual Evidence Profile and Summary of Qualitative Findings table should be essential components of undertaking qualitative evidence syntheses. This paper describes the end point of a CERQual assessment and should be read in conjunction with the other papers in the series that provide information on assessing individual CERQual components.
Written by leaders of qualitative methodology and edited by one of the biggest names in the field, this book provides up-to-date and interdisciplinary insight into a range of qualitative methods. ...Bringing together different perspectives, contributors discuss theoretical underpinnings of these methods before taking readers through the process of each approach and helping them develop skills needed to carry out this type of research autonomously and with confidence. Highlights of this new edition include: new chapters on multimethod qualitative research, using digital data and video, and addressing social issues in research, more guidance on how to store and manage data appropriately, advice on how to publish research in journals. Full of practical tips, exercises and summaries, this book continues to be a masterclass in qualitative research for students and researchers across the social sciences and beyond.
The purpose of this study was to review the distinction between formative- and reflective-indicator measurement models, articulate a set of criteria for deciding whether measures are formative or ...reflective, illustrate some commonly researched constructs that have formative indicators, empirically test the effects of measurement model misspecification using a Monte Carlo simulation, and recommend new scale development procedures for latent constructs with formative indicators. Results of the Monte Carlo simulation indicated that measurement model misspecification can inflate unstandardized structural parameter estimates by as much as 400% or deflate them by as much as 80% and lead to Type I or Type II errors of inference, depending on whether the exogenous or the endogenous latent construct is misspecified. Implications of this research are discussed.
Both academics and practitioners emphasize the importance for product firms of implementing service-led growth strategies. The service transition concept is well established, namely a unidirectional ...repositioning along a product-service continuum—from basic, product-oriented services towards more customized, process-oriented ones—ultimately leading to the provision of solutions. We challenge this service transition assumption and develop alternative ones regarding how product firms should pursue service-led growth. Using ‘problematization methodology’, and drawing on findings from thirteen system suppliers, we identify three service-led growth trajectories: (1) becoming an availability provider, which is the focus of most transition literature; (2) becoming a performance provider, which resembles project-based sales and implies an even greater differentiation of what customers are offered; and, (3) becoming an ‘industrializer’, which is about standardizing previously customized solutions to promote repeatability and scalability. Based on our critical inquiry, we develop two alternative assumptions: (a) firms need to constantly balance business expansion and standardization activities; and (b) manage the co-existence of different system supplier roles. Finally, we consider the implications for implementing service-led growth strategies of the alternative assumptions.
•We challenge the established service transition assumption•We identify 3 service growth trajectories: becoming an availability provider; a performance provider; and an industrializer•Firms should generally downsize and standardize solutions, thus being able to offer them to a greater number of customers•Firms concurrently hold a number of system supplier roles rather than transferring from one role to another•We present a strong platform for further examination of theoretical and managerial implications of the study
