Content Validity |
Adequate: Domain of the construct assessed was clearly defined and items were representative of the domain
Good: In addition to criteria for an adequate rating, measure was evaluated by judges (e.g., experts, participants)
Excellent: In addition to criteria for a good rating, measure development involved multiple groups of judges and quantitative ratings
|
Not modified |
Construct Validity |
Adequate: Replicated evidence of various types of construct validity (e.g., predictive, concurrent, convergent, discriminant) by independent research groups
Good: Majority of evidence by independent research groups across multiple types of construct validity
Excellent: In addition to criteria for a good rating, there is evidence of incremental validity with respect to clinical data
|
Adequate: Two or more independent research groups assessed construct validity with respect to one health-related outcome,a sociodemographic factors (i.e., distinguishing differences between groups), or other measures of adherence/self-management
Good: Two or more independent research groups assessed construct validity across two or more health-related outcomes, sociodemographic factors, or other measures of adherence/self-management
Excellent: Two or more independent research groups assessed construct validity across two or more health-related outcomes, sociodemographic factors, or other measures of adherence/self-management and demonstrated incremental validity (e.g., iterative versions of the measure showing improvement over time or adaptations of the same measure comparing versions in the same sample)
|
Validity Generalization |
Adequate: Some evidence supports using the measure with either more than one specific group or in multiple contexts
Good: Majority of evidence supports using the measure with more than one specific group or in multiple contexts
Excellent: Majority of evidence supports using the measure with more than one specific group and in multiple contexts
|
Adequate: One or two independent research groups demonstrated use of the measure in more than one demographic groupb or in multiple contextsc
Good: Three or more independent research groups demonstrated use of the measure in more than one demographic group or in multiple contexts
Excellent: Three or more independent research groups demonstrated use of the measure in more than one demographic groups and in multiple contexts
|
Treatment Sensitivity |
Adequate: Some evidence of sensitivity to change pre–post treatment
Good: Majority of evidence by independent research groups demonstrates sensitivity to change pre–post treatment
Excellent: In addition to criteria for a good rating, evidence of sensitivity to change across different treatments
|
Adequate: One study that demonstrates sensitivity to change pre–post treatment
Good: Two studies from independent research groups that demonstrate sensitivity to change pre–post treatment
Excellent: More than two studies by independent research groups that demonstrate sensitivity to change pre–post treatment
|
Clinical Utility |
Adequate: Measure data are clinically useful while taking into account factors including cost, ease/availability of administration and scoring instructions, etc.
Good: In addition to criteria for an adequate rating, there is published evidence that using the measure results in clinical benefits
Excellent: In addition to criteria for an adequate rating, there is evidence by independent research groups that using the measure results in clinical benefits
