Abstract
A psychometric evaluation of the questionnaire 'Self-Evaluation of Communication Experiences after Laryngeal Cancer' (S-SECEL) addressing communication dysfunction in patients with laryngeal cancer was carried out. Ninety-three patients with laryngeal cancer were studied. For comparison of response patterns and external validation, 21 patients with non-small cell lung cancer (NSCLC) and 26 patients with hoarseness, caused by benign laryngeal disease, were included in the analysis. The patients completed three questionnaires; the S-SECEL, the Sickness Impact Profile (SIP) and the Hospital Anxiety and Depression scale (HAD). The S-SECEL questionnaire was well-accepted by the patients, compliance was satisfactory, and missing value rates were low. The reliability of the S-SECEL was satisfactory for the Environment and Attitude subscales, whereas the General subscale did not reach the reliability levels recommended for group comparisons. In general, the response pattern in the three diagnostic groups and the pattern of correlations between the S-SECEL scores and the SIP- and HAD-subscales and dimensions lent support to the construct validity of the S-SECEL.
