The Construct Validity of Ryff's Scales of Psychological Well-Being (SPWB) and their Relationship to Measures of Subjective Well-Being

The factor structure of Ryff's Scales ofPsychological Well-Being (SPWB) and theirrelationship to standardized measures ofsubjective well-being (SWB) were investigated.Two hundred seventy-seven participants rangingin age from 18 to 48 years were administeredthe Memorial University of Newfoundland Scaleof Happiness (MUNSH), the Satisfaction WithLife Scale (SWLS), and the SPWB. Results failedto support either the hypothesis thatperforming factor analytic procedures on theitems of the SPWB should produce a six-factorsolution, with scale-specific items loadingmost highly on their respective factors or thehypothesis that subjecting the sub-scales ofthe SPWB to factor analytic procedures alongwith standardized measures of SWB would produceone higher-order well-being factor. Instead,item loadings clustered around three majorfactors that could not be identified with thesix scales proposed by Ryff. Moreover, thefactor analysis of SPWB and SWB scale totalsproduced three, instead of one, higher-orderfactors. Implications of findings are discussedwith respect to the relationship of the PWBconstruct to the SWB construct.
