The CSQ-4 contains the core 3 item set plus an item measuring improvement of client self-efficacy – capacity to cope and change adaptively. The CSQ-4 is available in all CSQ translations.

This core set of CSQScales® items reprises the empirical item selection of the CSQ-3 item set and adds an additional item measuring improvement in self-efficacy (“Have the services helped you deal more effectively with your problems?”) The CSQ-4 is available in all CSQ translations. Psychometric properties, operating characteristics, and coefficient alpha are very strong for this measure. The CSQScales® Reprint Portfolio presents publications that describe the history of the development and use of the CSQScales®.
