The CSQ-18B includes the items that comprises the CSQ-8 plus ten additional items systematically selected from the CSQScales® empirical item pool. Available in many languages, including English and Spanish, the CSQ-18B is a longer instrument and offers broader scope in topical coverage plus stronger leverage on sensitivity and reliability required to detect differences between research or intervention groups. Psychometric properties, operating characteristics, and coefficient alpha are very strong for this measure — and the CSQ-18A, as well. The CSQ CSQScales® Reprint Portfolio presents publications that describe the history of the development of the CSQScales®.
