context_page_description: The self-perceived quality-of-life scale is a psychological assessment instrument which is based on a comprehensive theory of the self-perceived quality of life and provides a multi-faceted measurement of health-related and non-health-related aspects of well-being. 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.
  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. For example, the treatment of a phobia may reduce fear, which could lead to the improvement of social relations and, in turn, performance at work, resulting in an increase in salary. Hence, in order to detect all implications of a treatment, a comprehensive measurement across multiple domains of an individual's life is needed. The SPQL scale can provide such a comprehensive measurement.
  The scale is designed in an electronic format. The software calculates scores automatically; this allows for advanced quantification methods.
context_section_description: As people approach a life stage in their development, they face developmental tasks that they need to master in order for the transition to the next life stage to be successful. The cycle of transition from one life stage to another is marked by three phases:
  Mastering or failing a task;
  Consequential reevaluation of life circumstances, values, and self-concept; and
  Adjustment and adaptation to new values and circumstances.
  To a lesser degree, cycles of transitions occur continually within major life stages on annual and even on daily bases.
  A curve of SWB throughout the lifespan can reflect the experience of an individual's good life. Ideally, all three SPQL axes should be evaluated for each life stage. However, this would make a questionnaire too long. Although the SPQL scale measures only one SPQL axis (SWB) for each life stage, the developed theoretical framework discusses the evaluation of all three SPQL axes throughout the major life stages. Thus, the framework can support the development of a next version of the scale that would accomplish this goal. Future research could explore possibilities for reducing the number of the evaluated scale items and include questions that will evaluate all three SPQL axes throughout the major life stages.
