The assessment of executive functions poses researchers with several challenges related to both the complexity of the construct of executive functions itself and/or the methodological difficulties related to its evaluation. The main objective of the current study was to evaluate a 360° version of an ecologically valid assessment called the Picture Interpretation Test (PIT). Participants included 19 patients with Parkinson’s disease (PD) and 19 healthy controls. All participants endorsed globally positive experiences of the PIT 360°. Furthermore, findings indicated that patients with PD took longer to correctly interpret the PIT 360° scene and tended to significantly focus on details of the 360° scene instead of the most informative elements. The time needed for a correct interpretation of the presented scene also correlated significantly with performance in conventional paper and pencil tests of executive functions for patients with PD. Classification analysis indicated the potential of the PIT 360° for distinguishing between patients with PD and healthy controls. Overall, these data provide preliminary evidence in support of the PIT 360° for evaluating executive functions.

Executive functions are crucial for performance of everyday activities. In Multiple Sclerosis (MS), executive dysfunctions can be apparent from the early onset of the disease. Technology-based time-efficient and resource-saving tools for early evaluation of executive functions using an ecological approach are needed to assess functional performance in real-life. The aim was to compare the efficiency of the Picture Interpretation Test 360° (PIT 360°) with traditional measures on executive dysfunction in Persons with Multiple Sclerosis (PwMS) and Healthy Controls (HC). Participants were 31 patients with Relapsing-Remitting MS (mean age = 44.323 ± 13.149; mean Expanded Disability Status Scale = 2) and 39 HC (mean age = 39.538 ± 15.728). All were tested with standard neuropsychological tests of executive functions, PIT 360°, and measures of user experience. While standard neuropsychological tests failed to differentiate between PwMS and HC group, the PIT 360° was successful in detecting executive dysfunction in PwMS. All participants reported the PIT 360° to be an engaging tool and endorsed positive reactions to their experience. Overall, the PIT 360° is a quick, sensitive, and ecological tool that captures real-world executive dysfunction in PwMS. This engaging measure is sensitive for the detection of executive deficits since the early phases of the disease.
