The ability of clinical trials and research studies to produce valid and generalizable results are harmed by low accrual rates. While there are a number of barriers which impede participation, it is important to improve potential participants' understanding of concepts related to clinical trials to ensure informed consent or refusal. Animations were proposed as a medium to help patients to better understand and navigate clinical trials. The present study consisted of an experiment comparing several communication strategies (animations, brochures with visuals, brochure without visuals, and materials from the NIH), with several key concepts useful to understand inform consent and trial participation (placebo, randomization, patient protection, steps to enroll). The experiment was based on the principles of the Cognitive Affective Theory of Multimedia Learning, the Elaboration Likelihood Model, The Heuristic Systematic Model, and the literature on technology acceptance. Several hypotheses assessed the effects of animation on individuals' perceptions and cognitive responses. Cognitive absorption was proposed as a mediating variable to explain the discriminant effects of animations over traditional communication strategies. A total of 1194 cancer patients' and survivors' responses were analyzed. Overall, all of the experimental conditions were more effective than the materials from the NIH. There are four other key findings from this research. First, lay language proved to be fundamental to improving both knowledge and attitudes toward clinical trials, regardless of the channel used. Second, animations were an effective strategy to communicate about clinical trials and medical research concepts, particularly for individuals with low motivation to process this information. Third, animations elicited more positive emotional responses in comparison with the materials from the NIH. Finally, cognitive absorption mediated the relationship between the channel used and how individuals responded to the messages. The dissertation concludes with the a discussion of the implications of these findings as well as a trajectory for future research.

520 $a La capacita della sperimentazione clinica e degli studi di ricerca di produrre risultati validi e generalizzabili e lesa da bassi tassi di partecipazione. Sebbene esistano numerosi ostacoli che impediscono la partecipazione, e importante migliorare la comprensione da parte dei potenziali partecipanti dei concetti relativi alle sperimentazioni cliniche per garantire il consenso informato o il rifiuto informato. Le animazioni sono state proposte come mezzo per aiutare i pazienti a comprendere e guidare meglio le sperimentazioni cliniche. Il presente studio consiste in un esperimento che confronta diverse strategie di comunicazione (animazioni, opuscoli con immagini, brochure senza elementi visivi e materiali dal NIH), con diversi concetti chiave utili a comprendere il consenso informato e la partecipazione al trial (placebo, randomizzazione, protezione del paziente, passaggi necessari per iscriversi ad un trial). L'esperimento e' basato sui principi della Cognitive -Affective Theory of Multimedia Learning, dell' Elaboration Likelihood Model, dell'Heuristic Systematic Model, e della letteratura sull'accettazione della tecnologia. Diverse ipotesi hanno valutato gli effetti dell'animazione sulle percezioni e sulle risposte cognitive degli individui. L'assorbimento cognitivo e stato proposto come variabile mediatrice per spiegare gli effetti discriminanti delle animazioni rispetto ad strategie di comunicazione tradizionali. Sono stati analizzati un totale di 1194 questionari compilati da pazienti malati di cancro e pazienti in remissione. Nel complesso, tutte le condizioni sperimentali sono risultate piu efficaci dei materiali utilizzati dall'NIH al tempo dell'esperimento. L'esperimento ha fornito altri quattro risultati chiave. Innanzitutto, il linguaggio comune utilizzato si e dimostrato fondamentale per migliorare sia le conoscenze che gli atteggiamenti nei confronti della sperimentazione clinica, indipendentemente dal canale di comunicazione utilizzato. In secondo luogo, le animazioni si sono dimostrate una strategia efficace per fornire informazioni circa la ricerca medica, in particolare per le persone con bassa motivazione a elaborare queste informazioni. Terzo, le animazioni hanno suscitato risposte emotive piu positive rispetto ai materiali dell'NIH. Infine, l'assorbimento cognitivo ha mediato la relazione tra il canale utilizzato e il modo in cui gli individui hanno risposto ai messaggi. La dissertazione si conclude con una discussione sulle implicazioni di queste scoperte e una traiettoria per la ricerca futura.
