Adequacy of item generation process | ||||
Derivation of items is appropriate | The study population’s representativeness of the target population is questionable with no evidence to support semi-structured nature of interviews | Limitations exist; did not conduct concept elicitation for target population as content validity was assumed | The study population’s representativeness of the target population is questionable with no evidence to support semi-structured nature of interviews | Limitations exist; did not conduct concept elicitation for target population as content validity was assumed |
Derivation of items is comprehensive | No evidence that concepts affected majority of patients representing the target population or whether a wide range of patients representing target population were used. No evidence of achievement of saturation, except statement in text (e.g., no saturation grid) | Limitations exist; did not conduct concept elicitation for target population as content validity was assumed | No evidence that concepts affected majority of patients representing the target population or whether a wide range of patients representing target population were used. No evidence of achievement of saturation, except statement in text (e.g., no saturation grid) | Limitations exist; did not conduct concept elicitation for target population as content validity was assumed |
Adequacy of cognitive interviewing process | ||||
Cognitive interviewing with patient input | Limitations exist concerning the representativeness of the study population to the target population and insufficient documentation of details | Limitations exist; did not conduct cognitive debriefing for target population as content validity was assumed | Limitations exist; target population and documentation of details | Limitations exist; did not conduct cognitive debriefing for target population as content validity was assumed |
Cognitive interviewing until saturation is reached | No evidence of achievement of saturation, except statement in text (e.g., no saturation grid) | Limitations exist; did not conduct cognitive debriefing for target population as content validity was assumed | Limitations exist; target population and insufficient documentation of details | Limitations exist; did not conduct debriefing for target population as content validity was assumed |
