This thesis offers a broad overview of EXecutive-functions Innovative Tool 360° (EXIT 360°) development from its concept to validation as a sensitive instrument for evaluating executive functionality (EF). Identifying early strategies to detect executive impairments appears a priority since executive dysfunction represents a significant health problem due to its high negative impact on daily activities. Therefore, we conceptualized and developed EXIT 360°, a new 360°-based instrument for an ecologically valid assessment of EF. It consists of a new task delivered via smartphone and a comfortable head-mounted display, where participants must perform seven everyday subtasks in 360° domestic environments. The three main psychometric properties of EXIT 360°—usability, convergent and construct validity—have been the focus of the studies discussed in this thesis. Usability studies involving patients and healthy subjects showed EXIT 360° is a straightforward, usable, and easy-to-learn technological instrument. Convergent validity study displayed a correlation between EXIT 36o° scores and standardized paper-and-pencil tests for EF. Finally, the construct validity study showed the effectiveness of EXIT 360° in discriminating between pathological and control groups with high precision, displaying its higher diagnostic accuracy compared to traditional tests. Overall, findings offer clear evidence that EXIT 360° must be seen as a valuable and innovative instrument for an ecologically valid evaluation of EF, highly usable for prompt diagnosis and early patient enrolment in focused rehabilitation.
Questa tesi offre un'ampia panoramica dello sviluppo di EXecutive-functions Innovative Tool 360° (EXIT 360°), dalla sua progettazione alla validazione come strumento sensibile per la valutazione della funzionalità esecutiva (FE). Identificare strategie precoci per rilevare i deficit esecutivi appare una priorità, dal momento che la disfunzione esecutiva rappresenta un problema significativo a causa del suo impatto sulle attività quotidiane. Pertanto, abbiamo ideato e sviluppato EXIT 360°, un nuovo strumento che sfrutta la tecnologia 360° per una valutazione ecologicamente valida del FE. Si tratta di un nuovo compito fruibile tramite smartphone e visore per la realtà virtuale, in cui i partecipanti devono eseguire sette compiti giornalieri in ambienti domestici. Le tre principali proprietà psicometriche di EXIT 360° —usabilità, validità convergente e di costrutto— sono state il focus degli studi discussi in questa tesi. Gli studi sull'usabilità hanno dimostrato che EXIT 360º debba essere considerato uno strumento tecnologico semplice, usabile e facile da apprendere. Lo studio di validità convergente ha mostrato una correlazione tra i punteggi di EXIT 360° e i test standardizzati carta-e-matita per il FE. Infine, lo studio di validità di costrutto ha mostrato l'efficacia di EXIT 360° nel discriminare il gruppo patologico da quello di controllo, evidenziando una maggiore accuratezza diagnostica rispetto ai test tradizionali. Nel complesso, i risultati offrono una chiara evidenza che EXIT 360° debba essere visto come uno strumento valido e innovativo per una valutazione ecologicamente valida del FE, altamente utilizzabile per una diagnosi tempestiva e l’arruolamento precoce del paziente in una riabilitazione mirata.

Abstract
This thesis offers a broad overview of EXecutive-functions Innovative Tool 360° (EXIT 360°) development from its concept to validation as a sensitive instrument for evaluating executive functionality (EF). Identifying early strategies to detect executive impairments appears a priority since executive dysfunction represents a significant health problem due to its high negative impact on daily activities. Therefore, we conceptualized and developed EXIT 360°, a new 360°-based instrument for an ecologically valid assessment of EF. It consists of a new task delivered via smartphone and a comfortable head-mounted display, where participants must perform seven everyday subtasks in 360° domestic environments. The three main psychometric properties of EXIT 360°—usability, convergent and construct validity—have been the focus of the studies discussed in this thesis. Usability studies involving patients and healthy subjects showed EXIT 360° is a straightforward, usable, and easy-to-learn technological instrument. Convergent validity study displayed a correlation between EXIT 36o° scores and standardized paper-and-pencil tests for EF. Finally, the construct validity study showed the effectiveness of EXIT 360° in discriminating between pathological and control groups with high precision, displaying its higher diagnostic accuracy compared to traditional tests.
