I am using a survey that contains several questions about various dimensions of performance for policy research institutes. Here, performance in the policy arena is unpacked into things like:
- quality of research,
- overall ability to engage with policy stakeholders,
- quality of recommendations, overall support to, and influence on, policymakers,
Each question has a typical 5-level ranking (i.e., ordinal response from "strongly disagree" to "strongly agree", or "very bad" to "very good").
I am thinking of pursing either of two options:
Creating a sort of composite measure, where all dimensions of performance are aggregated together so as to have one composite variable of "performance". I could then use this composite variable as the dependent variable (perceptions of performance).
Combining 20 of these questions to create a performance index. For each dimension, responses range between 1 and 5. So total scores on the index would thus range from a minimum of 20 up to a maximum total of 100 points. This index could also be used as a dependent variable. Or perhaps only for descriptive statistics.
Does this make sense? Any advice and reference would be greatly appreciated.
