This appendix presents details of a range of different measures that have been developed to assess identity, health, and well-being. It updates and extends a similar appendix to The Social Cure (Jetten, Haslam, & Haslam, 2012, pp. 345–367). There are two reasons why we collated these measures in that volume and why we have done so again here. First, we wanted to provide readers with a sense of how the key constructs that we have discussed in the foregoing chapters are typically assessed. Second, we were keen to provide a practical resource that readers might find useful in their own work.
