Abstract
Abstract The aim of this study was to develop the Adult Attention-Deficit/Hyperactivity Disorder Screening Inventory, a self-report instrument for assessing symptoms as well as to verify the internal structure of the instrument. Based on the proposed Diagnostic and Statistical Manual of Mental Disorders V Attention-Deficit/Hyperactivity Disorder diagnostic criteria, the Screening Inventory was developed and administered. The participants were 421 individuals divided into two groups, with and without Attention-Deficit/Hyperactivity Disorder diagnosis. The instrument items were analyzed and validated for content by a panel of expert judges. It was found that the instrument structure is composed of two factors, namely, Inattention and Hyperactivity/Impulsivity (Cronbach’s alpha 0.97 and 0.96, respectively). In general, the observed data provided validity evidence based on content and internal structure of the instrument, which complies with the latest edition of the Diagnostic and Statistical Manual of Mental Disorders, proving to be a favorable instrument for the investigation of Attention-Deficit/Hyperactivity Disorder symptoms in Adults.

The aim of this study was to develop a tool for assessing symptoms of Attention-Deficit/Hyperactivity Disorder (ADHD) in adults; we verified the psychometric properties, validity evidence based on content and internal structure, and reliability indices for internal consistency of the instrument
The first stage describes the development of the instrument, “Adult ADHD Screening Inventory” (Inventário de Rastreamento do TDAH em Adultos), and the second stage addresses the analyses conducted to determine the internal structure of the instrument
Summary
O objetivo do presente estudo foi desenvolver o Inventário de Rastreamento do Transtorno do Déficit de Atenção e Hiperatividade em Adultos, bem como verificar a estrutura interna do instrumento. Os dados observados fornecem evidências de validade com base no conteúdo e na estrutura interna para o instrumento, que está de acordo com a última edição do Manual Diagnóstico e Estatístico dos Transtornos Mentais, mostrando-se favorável para investigação dos sintomas de Transtorno do Déficit de Atenção e Hiperatividade em adultos. ADHD patients have difficulty concentrating on tasks, caused by inattention, and mental or motor restlessness, triggered by hyperactivity/impulsivity, which impair daily activities and affect their social, academic, professional, and emotional life, in addition to increasing health risks (APA, 2013; Benczik, Schelini, & Casella, 2010; Biederman, 2005; Lopes, Nascimento, & Bandeira, 2005; Louzã, 2010; Mattos, 2010). As of the 1970s, follow-up studies found that the behavioral patterns of children persisted when they reached adulthood, highlighting the need for research on the occurrence of the disorder during development
