Assessment of well-being in the clinic: Using the state version of the short Scale of General Well-Being as a clinical outcome measure.

Abstract

Interest in the concept of well-being within clinical and applied psychology settings has increased, highlighting a need to develop appropriate measures. The aim was to adapt and test the validity of the 14-item Scale of General Well-Being (14-SGWB) originally developed by Longo et al. (2018), as a clinical outcome measure. Study 1 is a psychometric study with 543 nonclinical participants, the wording of the 14-SGWB was adapted, and tested for reliability and convergent validity. Study 2 investigated the adapted version with 125 clients over 10 therapy sessions, examining sensitivity, and reliable change cut-off. The final 14-SGWB-clinical tool has a single component structure, good convergent validity, and can assess reliable and clinically significant change. Measures that assess positive psychological change are important for the future development of clinical and applied psychology. The 14-SGWB-ct offers researchers a measure to extend evaluations of interventions to the effects on well-being.
