Abstract:
Topic: Cancer patients experience multiple debilitating symptoms. Reliable and valid instruments, preferably with international distribution, are essential to assessment and in turn management of symptoms. Purpose: Evaluate the psychometric properties of the Icelandic MDASI (M.D. Anderson Symptom Inventory) questionnaire, a brief measure of severity and interference of cancer related symptoms. Framework: MDASI was developed by Charles Cleeland and colleagues and derives from a long program of research on cancer related symptoms. Methods: The MDASI was translated to Icelandic and back-translated to English. First, it was evaluated by six oncology nurses and then administered to a convenience sample of 135 cancer patients undergoing treatment at the Oncology/hematology division at Landspitali University Hospital in Reykjavik. Participants were 79 women (58.5%) and 56 men (41.5%) with a mean age of 59 (SD=12.5). In addition to the MDASI, participants completed the Positive and Negative Affect Scales (PANAS), and a single item assessing quality of life (QOL). Reliability was assessed with Cronbach's alpha. Pearson's correlation and Factor Analysis were used to assess the validity of the MDASI. Findings: Reliability is good for both the severity scale (alpha=0.87) and the interference scale (alpha=0.84). Validity is supported by a positive correlation between the negative scale on the PANAS and the MDASI severity scale (r=0.42; p<.01), and the MDASI interference scale (r=0.45; p<.01). It is also supported by a negative relationship between QOL and the MDASI severity scale (r=-0.38; p<.01), and the MDASI interference scale (r=-0.40; p<.01). Factor analysis did not support the usual two-factor structure of the MDASI (severity and interference). Instead, it revealed a four factor structure; 1) cognitive symptoms and interference items, 2) gastro-intestinal symptoms, 3) pain and shortness of breath, and 4) psychological symptoms and interference with relationships and enjoyment of life. The reliability and validity of the Icelandic MDASI are partly supported but warrant further investigation. The factor structure, in particular, needs further examination since it could be explained by cultural differences or the translation of the instrument. Despite this, it is recommended that the MDASI be used to assess symptoms among Icelandic cancer patients.
