Validation and application of the Arabic version of the M. D. Anderson symptom inventory in Moroccan patients with cancer.

Little is known about symptom burden-a concept encompassing both symptom severity and the degree of symptom interference with daily living-in patients with cancer in Morocco or other countries with Arabic-speaking populations. The goal of this study was to psychometrically validate the Arabic version of the M. D. Anderson Symptom Inventory (MDASI-A), a tool for measuring multiple symptoms in patients with cancer, and to test its utility in a sample of patients with late-stage cancer in Morocco. The MDASI-A was developed by standard forward-backward translation of the English MDASI. We used nonidiomatic Arabic in the MDASI-A to enhance its possible usefulness for all Arabic-speaking patients with cancer. One hundred sixty-five Arabic-speaking patients with various cancer types were recruited from a city hospital in Rabat, Morocco. The MDASI-A was administered by interview, as only 5% of the patients had a high school education. Psychometric analysis demonstrated acceptable internal consistency, with Cronbach alpha values of 0.85 for all 19 items, 0.78 for symptom severity items, and 0.79 for interference items; known-group validity was demonstrated by significant differences in mean symptom severity and interference between patients with good vs. poor performance status. All patients had moderate to severe pain and were taking pain medications. Additional severe symptoms included fatigue, lack of appetite, and disturbed sleep. Patients with gastrointestinal or gynecological cancer reported relatively more symptom severity than patients with breast or lung cancer. Poor performance status, male gender, and current infection were significant predictors of high symptom interference (R(2)=0.48, P<0.05). The MDASI-A is a valid and reliable patient-reported outcome instrument that can be used to assess Moroccan Arabic-speaking cancer patients' multiple symptoms. Its utility for use in other Arab countries needs to be tested.

Validation and application of a module of the M. D. Anderson Symptom Inventory for measuring multiple symptoms in patients with gastrointestinal cancer (the MDASI-GI).

The M. D. Anderson Symptom Inventory (MDASI) was developed as a brief yet comprehensive tool to assess patient-reported symptom severity and interference in patients with cancer. The authors report the development of an MDASI module for use in patients with gastrointestinal (GI) cancer (the MDASI-GI). Patients with GI cancer (N = 184) participated in module development and validation. The process included: 1) generating GI-specific candidate items with input from GI oncologists and from qualitative interviews with patients and adding those items to the core MDASI for testing; 2) dropping candidate GI items that lacked sensitivity; 3) validating the psychometric properties (validity, reliability, sensitivity) of the resulting MDASI-GI; and 4) conducting cognitive debriefing interviews with patients to confirm the questionnaire's ease of comprehension, relevance, and acceptability. Five GI-specific symptom items (constipation, diarrhea, difficulty swallowing, change in taste, and feeling bloated) were added to the original 19 MDASI symptom and interference items to form the MDASI-GI. Sixty-one percent of the sample had 1 or more moderate-to-severe symptom(s) (>or=5 on a severity scale from 0 to 10). Cronbach alpha values were .80 and .87 for symptom severity items and interference items, respectively. Known-group validity (sensitivity) was supported by the ability of the MDASI-GI to detect significant differences in symptom and interference levels according to performance status (P < .001). Cognitive debriefing demonstrated that, for patients, the MDASI-GI was an easy-to-use and understandable tool. The current results indicated that the MDASI-GI is a valid, reliable, and concise tool for measuring symptom severity and interference with function in patients with GI cancer.
