Primary use / Purpose:
In this study, passionate love has been defined as "a state of intense longing for union with another." Perhaps at no other time is passionate love experienced more intensely than during adolescence. Researchers who are conducting research into Passionate Love often need two identical sets of tests of Passionate Love: One for pre-test and one for post-test. The Passionate Love Scale (PLS) Form B is an alternative form, with slightly different but equivalent questions.
A 30-item scale (often shrunk into a 15-item measure) with each item having a blank space where respondents are directed to fill in the name of their partner. Each item is answered on a 9-point scale ranging from 1 (not at all true) to 9 (definitely true). For psychometric description see: Hatfield, E. & Sprecher, S. (l986).
