Evidências de validade de escala para rastreio da violência contra a pessoa idosa

Abstract

Objective: To construct and verify validity evidence for a screening scale for violence against elderly people Method: This is a methodological study for the construction and validation of a screening scale for violence against elderly people. It was developed in three phases: theoretical, empirical and analytical. The theoretical stage was composed of a scope review, a concept analysis and data collection with nurses. After data analysis, the scale for screening violence against elderly people was constructed. In the empirical phase, content validation was performed with expert judges and with elderly people, and in the analytical phase, the content validity and internal reliability indices of the instrument were determined. Results: the constructed instrument has 65 items, organized in a Likert-type scale (1 to 4), divided into six facets referring to the typifications of violence against the elderly, namely: psychological violence with 14 items, financial violence with 15 items, abandonment with seven items, neglect with eight items, physical violence with 13 items, and sexual violence with eight items. The overall assessment of all indicators was considered acceptable. The CVI remained nearly perfect, with CVI = 0.99 across the four domains (clarity, relevance, relevance, and semantics). The overall CVC was also rated excellent in all four facets: CVCclarity= 0.96, CVCpertinence= 0.98, CVCrelevance= 0.98 and CVCsemantic= 0.96. Regarding Fleiss' Kappa, the evaluation of semantics gave the lowest value KFsemantics=0.82, followed by clarity KFclarity= 0.85 and KFpertinence= 0.94 and KFrelevance= 0.94. Regarding the complete instrument the median was Md = 91.50 points, the range AT= 81.00 and α = 0.89, being considered excellent. Conclusions: the instrument is recommended for use in the elderly public because it has consistent content validity evidence and reliable internal structure-based evidence.
