13 items on symptoms, and 6 items on symptom interference with daily functions11-point Likert-scale, 0=not present and 10=as bad as you can imagineDeveloped for cancer setting
German version: Cronbach alpha 0.82 (symptom intensity) and 0.84 (interference)54
6 items on patient’s perceived self-efficacy10-point Likert-scale, 1=not at all confident and 10=totally confidentDeveloped for chronic conditions, applied in cancer settings
German version: construct validity r=0.578, p<0.001; internal consistency: Crohnbach alpha 0.9355
LASA Mood Scale
1-item: emotional well-beingVisual Analogue Scale (100 mm), 0=happy
Concurrent validity between LASA Mood Scale and a comprehensive 28-item adjective checklist (original in German: Befindlichkeitsskala BfS) was acceptable (median r=0.6, p<0.001) with breast cancer patients, and has proven to be valid for emotional distress screening72
