Overview of the full questionnaire matrix with number of completers (n=965) and noncompleters (n =52). The figure displays the order of questions as presented to the patients. After the PI screening item, there were different paths automatically selected by the computer based on the PI score; Path A: with a PI score <1, there were no further pain questions and patients were automatically routed to the items on physical functioning; Path B: with a PI score ≥1, there was one section on general pain, neuropathic pain (painDetect), and pain etiology and one screening question on BTP, leading to one of the two automatically selected paths; Path B1: if BTP was confirmed, the computerized version of the Alberta BTP tool was administered; Path B2: with no BTP, patients were given a shorter modified version of the Alberta BTP tool on general pain relief. Paths B1 and B2 were then routed to the items on physical functioning. Patients who confirmed weight loss on the SGA were given one extra item on nutritional intake before proceeding to the final items. Maximum number of items are as follows: Path A, 79; Path B1, 167; and Path B2, Percentage of noncompleters; 2scored on a 0–10 NRS; 3total number of items in the computerized version used differed from the number in the traditional paper versions to allow for multiple response options. PI=pain intensity; BTP=breakthrough pain; SGA=Subjective Global Assessment of Nutritional Intake; NRS=numerical rating scale; ESAS=Edmonton Symptom Assessment System; EORTC QLQ-C30=European Organization for Research and Treatment of Cancer Quality of Life Questionnaire-Core 30; Alberta BTP tool=Alberta Breakthrough Pain Assessment Tool; PHQ9=Brief Patient Health Questionnaire.

Overview of number of completed items before aborting the assessment (noncompleters, n=52). 1The PI screening question routing patients to Paths B1 or B2 if PI≥1 was question no. 40; 2the BTP screening question for routing patients to the full or shorter modified version of the Alberta BTP Assessment Tool was question no. 53. PI=pain intensity; BTP=breakthrough pain.
