Cross-cultural Adaptation and Validation of the Dutch Version of SWAL-QoL

Abstract

The aim of this work was to translate the 44-item SWAL-QoL into Dutch (SWAL-QoL-NL) and compare the validity of this questionnaire against Euroqol in a Dutch population with dysphagia. SWAL-QoL was translated according to international guidelines. SWAL-QoL-NL and Euroqol were completed by 152 patients in seven diagnosis groups. Internal consistency and correlations were calculated. Scores for nine subscales (General burden, Food selection, Eating duration, Fear of eating, Sleep, Fatigue, Mental health, Social functioning and a symptom score) ranged between 0.80 and 0.92 (Cronbach's a). Two subscales (Eating desire and Communication scored 0.67 and 0.60, respectively, and were removed from the questionnaire. The 14-item battery on clinical symptoms showed an internal consistency of 0.80, allowing the use of a sum score on group level in clinical research. Correlation of SWALQoL-NL subscales with the Euroqol was negligible to low (Pearson's correlations range = 0.09-0.36). The 39-item SWAL-QoL-NL proved to be a reliable tool to examine the impact of dysphagia on quality of life in a Dutch population. Internal consistency allows the use of nine subscales of SWAL-QoL-NL for comparisons on a group level (0.80 \ a \ 0.92) only. Also a Symptom score can be derived from the raw data.

Protocolo para controle de eficácia terapêutica em disfagia orofaríngea neurogênica (PROCEDON)

“…Além disto, a conquista de um desses parâmetros isoladamente pode não causar impacto favorável para a qualidade de vida do paciente. A qualidade de vida do paciente disfágico tem sido uma preocupação mundial na atuação com disfagia orofaríngea [34][35][36] . A mudança do grau de comprometimento no quadro disfágico deste paciente, caracterizada pela presença de disfagia grave pré-fonoterapia e moderada pós-fonoterapia, respectivamente mostradas nas Figuras 2 e 4, comprova as mudanças conquistadas na dinâmica da deglutição e a possibilidade das escalas de grau de comprometimento contribuírem para mensurar a evolução terapêutica.…”

The Validation of the Chinese Version of the Swallow Quality-of-Life Questionnaire (SWAL-QOL) Using Exploratory and Confirmatory Factor Analysis

“…A question is added to find the frequency or degree of agreement of each item in each scale. Either a frequency scale (in question 3,5,6,9) or an evaluation scale (in question 1,2,4,7,8), in the form of a 5-point Likert scale, is the response option. All scales are linearly transformed into a 0-to-100 metric, with 100 indicating most dysfunction and 0 indicating no dysfunction.…”

“…The SWAL-QOL has been translated into Chinese in Singapore but has not yet been validated [2]. A standardized Dutch version of the SWAL-QOL is also available [7].…”

Pretreatment organ function in patients with advanced head and neck cancer: clinical outcome measures and patients' views

“…The advantage of the present questionnaire is that more specific function-related questions could be included. This is an important consideration, because truly function-specific questionnaires such as the MDADI and the Swalqol were not yet available in Dutch at the start of this research project [20,21]. The questionnaire was completed by the patients themselves in the presence and often with assistance of the first author (LM).…”
