SPF-IL

What are the dimensions of well-being? That is, what universal goals need to be realized by individuals in order to enhance their well-being? Social production function (SPF) theory asserts that the universal goals affection, behavioural confirmation, status, comfort and stimulation are the relevant dimensions of subjective well-being. Realization of these substantive goals and the perspective on opportunities to realize these goals in the future contributes to the affective and cognitive component of well-being. To measure levels of affection, behavioural confirmation, status, comfort and stimulation and empirically validate the dimensions of well- being, the SPF-IL scale was developed. The SPF-IL is a multidimensional instrument to measure the first-order goals that enable people to realize well-being. The frame of reference in the questionnaire is 3 months.

Answers are given on a four-point scale ranging from never (1) to always (4), with higher mean scores indicating greater well-being. Cronbach’s alpha values of the SPF-IL in many populations have proven good reliability. Furthermore, confirmatory factor analysis supported the dimensional structure of well-being indicating construct validity. The overall fit of the model was sufficient, in spite of the somewhat problematic measurement of status, and the test–retest study showed an acceptable level of stability. As for the content validity of the dimensions and their measurement, various sub-studies showed that the SPF-IL scale is a valid instrument, doing at least as well as popular measures of overall well-being but also specifying its dimensions.
