Personalized Psychological Flexibility Index (PPFI)

This survey measures the extent to which people pursue their goals despite the presence of stressors and challenges. To ensure participants respond to these items in a meaningful context, each item on psychological flexibility is in reference to a personally meaningful life goal. Participants are first asked to identify a life goal they are working on. Based on initial findings from pilot studies, we found support for three factors: avoidance (deflecting negative emotions and events that arise when pursuing a goal), acceptance (embracing emotions that arise when pursuing a goal), and harnessing (using negative emotions to fuel goal pursuit). To ensure that the goals participants recorded were central and meaningful to their lives, we added in four questions pertaining to the importance of the goal.

Self-Evaluated Quality of Life-Direct Weight measure (SEIQoL-DW)

The Schedule for the Evaluation of Individual Quality of Life (SEIQoL) is an interview-based instrument for the assessment of quality of life (QoL) of the individual. The SEIQoL has been used with a variety of patient groups, but its applicability may be limited in illnesses which impair cognitive functioning or motivational state. Successful completion of the SEIQoL requires, inter alia. insight into the factors which determine one’s quality of life. the ability to think abstractly and the ability to make judgments based on information presented in diagrammatic form. Therefore, its use with patients in whom these abilities are impaired may be problematic.
