Development and verification of internal structure of the Adult Attention-Deficit/Hyperactivity Disorder Screening Inventory
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.
