Abstract

Background.It has often been argued that if patients' success with speech rehabilitation after laryngectomy is limited, it is the result of lacking motivation on their part. This project investigated the role of motivation in speech rehabilitation.Methods.In a multicenter prospective cohort study, 141 laryngectomees were interviewed at the beginning of rehabilitation and 1 year after laryngectomy. Speech intelligibility was measured with a standardized test, and patients self-assessed their own motivation shortly after the surgery. Logistic regression, adjusted for several theory-based confounding factors, was used to assess the impact of motivation on speech intelligibility.Results.Speech intelligibility 1 year after laryngectomy was not significantly associated with the level of motivation at the beginning of rehabilitation (odds ratio [OR], 1.3; 95% confidence interval [CI], 0.7–2.3;p= .43) after adjusting for the effect of potential confounders (implantation of a voice prosthesis, patient's cognitive abilities, frustration tolerance, physical functioning, and type of rehabilitation).Conclusions.Motivation is not a strong predictor of speech intelligibility 1 year after laryngectomy.
