Evaluating implementation outcomes of a measure of social vulnerability in adults with intellectual disabilities

Abstract

Background: A test identified as valid and accurate in research will not automatically be considered appropriate by those involved in its use, or even be used in the first place. The Social Vulnerability Test-22 items [TV-22] is a measure specially designed for adults with intellectual disabilities (ID). This study aims to evaluate the implementation outcomes of the TV-22; more precisely its acceptability (e.g., complexity), appropriateness (e.g., perceived relevance) and the assessment fidelity (i.e., adherence to assessment guidelines) by special education practitioners.

Procedures: Thirty-one practitioners (8 psychologists, 11 educators, 12 special education center managers) administered the TV-22 during an interview with an adult with ID. Semi-structured interviews were conducted to collect practitioners' opinions on the acceptability and the appropriateness of the TV-22 for their clinical practice. Quantitative analyses were performed to assess the fidelity of the assessments and the influence of some personal factors.

Results: The results indicate a good appropriateness, a reasonable acceptability, - but a low assessment fidelity of the TV-22 by some practitioners. Psychologists stand out for a more rigorous use of the test.

Implications: Results highlight the importance of evaluating implementation outcomes when a new measure is developed to ensure its appropriateness and correct use by stakeholders.
