Welcome to the Measurement Instrument Database for the Social Sciences (MIDSS). The site is designed to be a repository for instruments that are used to collect data from across the social sciences. Please use the site to discover instruments you can use in your own research. We now have more than 500 instruments concerned with a wide range of topics (e.g. autism, health, pain). You can use the search function above to search the database using pre-identified keywords or generate your own terms to search the instrument titles. We are currently in a growth phase and don’t have staff dedicated to actively trawl the internet and scientific literature to find instruments for MIDSS. Rather, we rely on you to submit instruments that you have developed using a Wiki-type model. Please consider submitting any instruments that you have developed. It is relatively painless and will only take a few minutes. There is no requirement to register or create a password. By adding your instruments to this database you are making them available for colleagues to use, thus sharing knowledge. If your instrument is available for others to use, you are likely to benefit from this in the form of citations to your instrument and to your own published work relating to it.
