Development, validation and application of a Brazilian knowledge scale about sports doping in dentistry

Development and psychometric properties of a questionnaire about knowledge of lay people about traumatic dental injury

“…This methodology has been previously suggested and applied to the validation of other questionnaires without a previously validated "goldstandard" instrument. 25,26,29,30 Discriminant validity is the degree to which a construct differs from the others. 29 In the present study this parameter was evaluated through the hypothesis test of known groups.…”

“…25,26,29,30 Discriminant validity is the degree to which a construct differs from the others. 29 In the present study this parameter was evaluated through the hypothesis test of known groups. In this approach, different groups of individuals fulfill the survey instrument and the results of the groups are compared.…”

“…In convergent validity, the indicative items of a specific construction must have a common proportion of variance in relation to a previously validated tool with a similar outcome. 29 In the present work, we intended to make an analysis considering the result of the correlation between this instrument (TDI-Q) and another instrument with a similar construct, expecting results with high correlations between them. 25 However, no previously validated Brazilian questionnaire in Portuguese has been found for convergent validation and the correlation between the final score of the TDI-Q and the score of the self-assessment of knowledge about the TDI were assessed.…”

“…To evaluate the measurement model, it is common to verify the convergent and discriminant construction of the instrument. In convergent validity, the indicative items of a specific construction must have a common proportion of variance in relation to a previously validated tool with a similar outcome 29 . In the present work, we intended to make an analysis considering the result of the correlation between this instrument (TDI‐Q) and another instrument with a similar construct, expecting results with high correlations between them 25 .…”
