Internal consistency was excellent α = 0.94, and significant correlations were observed between quality of life (r = 0.627, p < .001), depression (r = -0.699, p < .001) and the Control, Autonomy, Self-realisation and Pleasure Scale (CASP-19; r = 0.73, p < .001).
The CASP-19 was significantly correlated in the expected direction with measures of quality of life (r = .707), depression (r = -.707) and additional measures.
Three well-being domains were also assessed on each occasion: life satisfaction (measured with the Satisfaction with Life Scale); quality of life (assessed with the CASP-19 scale); and depression symptoms (measured using the Centers for Epidemiologic Studies Depression Scale).
