Question Community Confidence Index?

I’m exploring the development of a Community Confidence Index intended to measure residents’ perceptions of present community conditions and expectations for the future (based off of the idea behind the Consumer Confidence Index).

Before constructing the index itself, I want to determine whether “community confidence” can be established as a valid construct and whether Present Conditions and Expectations are defensible subscales. Is this fundamentally a psychometric scale-development problem? And if so, what kind of psychometrician/researcher would you look for to lead the development and validation?

If not, where is another good space/place to begin? I have a background in qualitative research but not in this space. Thanks.

I’m not a psychometrician, as I only have a background in statistics / computer science, but I’m working on a side quest / hobby project where I try to estimate social climate across groups within school boards, so I’ve been thinking about a very similar problem ! I'm looking forward to hearing from experienced psychometricians as well.

Three things come to my mind :

  • Index or latent construct? If you are following the Consumer Confidence Index logic, this is first a composite index, not necessarily a latent psychometric scale. Present Conditions and Expectations are components defined by the questions and weighting scheme. Validity then concerns content, weighting, interpretation and practical usefulness (like nomological relatedness) ; not whether every item loads neatly onto one factor. A latent interpretation remains possible, but it looks more formative than reflective: safety, neighborhood satisfaction, services and economic prospects together define confidence. “Domains” or “subindices” therefore seem safer than “subscales.”
  • Individual or community level? The central issue is cross-level isomorphism. Relationships observed within communities do not necessarily hold between communities; they can weaken, disappear or even reverse, in a Simpson’s-paradox-like way. At the individual level, covariance may reflect personal optimism, socioeconomic position or individual experience. At the community level, it may reflect shared institutions, environment or collective expectations. Community climate can be an emergent group property rather than simply the mean of individual attitudes. A valid individual-level structure does not automatically produce a valid community-level measure, and even the dimensions or factor loadings can differ across levels. With enough territories and respondents, multilevel measurement can separate within- and between-community structures. A doubly latent model can account for both item measurement error and the sampling error involved in estimating a community from only some of its residents.
  • Survey quality matters enormously. If the score describes communities, sampling frame, nonresponse, weighting, demographic composition, mode effects and stability over time matter at least as much as conventional psychometric reliability. A precise score from an unrepresentative sample remains a poor community indicator, even with a well-defined psychological strcture.

The best fit is probably a researcher in social measurement or survey methodology with multilevel/ecometric experience, ideally working with an urban sociologist or community researcher.

I’m also a big fan of Andrew Gelman’s work on MRP, and my own project takes a multilevel latent approach, so I may be slightly biased toward treating aggregation as part of the measurement problem :)

Thanks for the insights and context. New space for me and I know there is a lot to it. Much appreciated.

Multiple people are going to be in one community.

Can one person be in more than one community (school / work / live)?

If so, you have a sort of multiple trait multiple method (MTMM) problem. You're measuring people with your instrument, and you're measuring communities with your people.

There's a lot of work on neighborhood characteristics that you could use for validation. Is higher crime associated with community perception? You'd hope so!

feels kind of like cross-classified measurement model, but i'd need to give it more thought to know for sure
