Outcome Measures

Primary Outcomes (2)

  • Construct validity of Mediterranean Colorectal Cancer Registry: answering multiple-choice items

    Construct validity will be based on the combination of qualitative and statistical methods in order to develop representative and structured set of multiple-choice items for colorectal cancer registry.

    2 week

  • Content validity of Mediterranean Colorectal Cancer Registry: answering multiple-choice items

    Content validity will be based on the combination of qualitative and statistical methods in order to develop shortest-possible but well-matched set of multiple-choice items reflecting the subjects being assessed in the colorectal cancer registry. .

    2 week

Secondary Outcomes (5)

  • Parallel forms reliability of Mediterranean Colorectal Cancer Registry: answering multiple-choice items

    2 week

  • Test-retest reliability of Mediterranean Colorectal Cancer Registry: answering multiple-choice items

    2 week

  • Split half internal consistency of Mediterranean Colorectal Cancer Registry: answering multiple-choice items

    2 week

  • Face validity of Mediterranean Colorectal Cancer Registry: binary scoring of items
