Outcome Measures

Primary Outcomes (3)

• Content validity

  It is the extent to which questions on the instrument and the scores from these questions represent all possible questions that could be asked about the content or skill. It will be measured by item content validity index and scale content validity indices.

  7 days

• Face validity

  The ability of an instrument to be understandable and relevant for the targeted population. It is the weakest way to establish the validity of the questionnaire. It motivates the respondents to answer more truthfully. It will be assessed by a panel of bilingual experts (clinicians, linguists, and researchers) who will reviewed the translated items for clarity, relevance, and cultural appropriateness.

  7 days

• Construct validity

  It refers to validating your constructs based on their pattern of correlations with other variables assumed to be indicators of or theoretically related to the construct of interest. It will be assessed by factor analysis, convergent and divergent validity.

  7 days

Secondary Outcomes (3)

• Internal consistency

  7 days

• Test-retest reliability

  7 days

• Feasibility of the Arabic Version of the Maine-Seattle Back Questionnaire (MSBQ)
