Primary use / Purpose:
The PLS is a 15 item likert-type questionnaire measuring various components of passionate love (cognitive, affective and behavioural).
Background:
While measures previously existed for companionate love, they did not exist for the more intense passionate love. The passionate love scale (PLS) can be used to explore cross-cultural differences, age differences and gender differences, among others, in passionate love.
Psychometrics:
Reliability is confirmed in Hatfield and Sprecher (1986), while convergent validity is discussed in several articles (Aron & Henkemeyer, 1995; Hatfield & Sprecher, 1986; Hendrick & Hendrick, 1989; Sprecher & Regan, 1998).
