This self-report instrument assesses perceived aliveness and available personal energy at the time of rating. The Subjective Vitality Scale (SVS) is intended to capture subjective vitality as distinct from transient mood and can be used in clinical, counseling, and research contexts.
The measure consists of 14 items and typically takes about 3 minutes to complete. Items query the respondent’s current sense of energy, vigor, and psychological liveliness, supporting brief screening and repeated measurement when monitoring change over time. The Subjective Vitality Scale (SVS) was originally developed by Ryan and Frederick.
