Table 3 Multi-trait scaling analysis

From: An international field study for the reliability and validity of the EORTC communication questionnaire EORTC QLQ-COMU26

  1. Multi-trait scaling analysis: Item-correlation Scale (Spearman Correlation) excluding item when calculating the Scale and Cronbach’s alpha after removing the item
  2. Cells in grey: item own scale correlation (corrected for overlap)
  3. Cells in white: correlations between the items and the other scales
  4. Numbers in bold: highest correlation of the item
  5. Items highlighted in green: higher correlation with a scale other than with its own scale
