Desenvolvimento do teste de planejamento Torre de Londres – versão brasileira (TOL-BR)

Executive functions allow individuals to solve complex problems and deal with new situations. Among these functions, planning is considered a high order function, strongly related to frontostriatal circuitry, and its deficits can be found in many disorders, such asautism, attention deficit hyperactivity disorder (ADHD) and depression. One of the instruments most widely used to assess such function is the Tower of London (ToL), which, despite good qualities, has been showing problems such as ceiling effect and low discriminative potential in normal individuals. The present study aims to assess the psychometric properties of a computerized Brazilian version of the Tower of London test (ToL-BR). All possible combinations (35) of items on ToL were tested; after exclusion of the less discriminative items, a total of 19 remained in ToL-BR. The preliminary results here presented, added to previous studies, suggest that this version of ToL is more adequate to assess individuals with inferior to medium planning skills.
