Abstract
OBJECTIVE
Develop and obtain content validity of a new tool for Evaluating and Classifying the Severity of Adverse Events for Psychotherapeutic Clinical Trials (EVAD).
METHOD
Study of the development process of EVAD in four stages: (1) identify the domain and concept definition through a literature review, (2) instrument design, (3) expert judgment of the EVAD items through Gwent's concordance coefficient, and (4) applicability.
RESULTS
In the absence of a consistent conceptual framework of adverse events in psychotherapeutic clinical trials, we have developed a framework and defined it. We have designed EVAD items and their complementary tool for rating adverse events. Content validation by expert judges resulted in CVR = 1.0 for each item and CVI = 0.79 in sufficiency, 0.76 in clarity, 0.91 in coherence and 0.95 in relevance for all items (p < 0.001). Final version of EVAD were applied to three participants for 7 weeks. Overall EVAD seems to be clear and meaningful for participants.
CONCLUSIONS
EVAD is a semistructured interview based on a consistent conceptual framework, and proven content validity following the most important guidelines described in the literature.
TRIAL REGISTRATION
