I have dataset that includes items measuring diagnostic criteria for personality disorders. For each criterion there are multiple items. For some of the criteria, respondents must respond yes to more than two items in order to meet that criterion. A criterion may have 5 items and thus multiple combinations of items would satisfy that criterion. Does anyone have experience scoring measures using Stata? Is there a way to include multiple combinations of items in an "if" statement without list all combinations? Please let me know if any of this is unclear.
