Self-perceived quality-of-life scale
[4] The scale has become an instrument of choice for monitoring quality of life in some clinical populations, for example, it was adopted by the Positively Sound network for women living with HIV.
[5] The improvement of mental disorders may have an effect on multiple domains of an individual's life which could be captured only through a comprehensive measurement.
Hence, in order to detect all implications of a treatment (e.g., for a phobia), a comprehensive measurement across multiple domains of an individual's life is needed.
The automatic calculations and quantification methods allowed undertaking a comprehensive approach for assessing SPQL from multiple facets.
A multi-facet approach, in turn, provided a comprehensive evaluation of the effectiveness of mental health interventions (through pre- and post tests).
[14][15][page needed] The scale focused on how individuals evaluate their lives and compare these measurements with the average good life of others.
The SPQL scale has implications for evaluating the effectiveness of a wide range of interventions intended to improve mental health and well-being.
Participants' responses on the inventories for each of the three SPQL axes (see Appendixes) provided the data for the psychometric validation of the scale and for the quantitative analyses that allowed measuring the good life.
People who have experienced more positive and less negative subjective affective experiences (SAE) during their lives (i.e., transient deviations), have a higher SPQL.
Individuals with the same score on SWB can differ in their evaluations of standards of living even if their objective life circumstances are alike.
Hence, in order to capture a more accurate measurement of SPQL, the strength and degree of fulfillment of a wide range of human needs and preferences for life circumstances was evaluated.
In order to measure fulfillment of needs, a broad range of human needs was sorted into four conceptually distinct categories that are (a) contingent on corresponding stages of cognitive and moral development,[26][27] (b) constitute major components of self-concept,[28] and (c) correspond to the neural activity in different clusters of anatomical brain regions.
