<P> An early review (1940) of romantic love in the Western world emphasized the persistent association of obstacles or grave difficulties with the intensity of love, as in Shakespeare's Romeo and Juliet . In 1972, Richard Driscoll; along with Keith Davis and Milton Lipetz, published results from a longitudinal study on relationships, suggesting an underlying truth to the popular impressions . The research suggests that parental interference in a love relationship can intensify the feelings of romantic love between members of the couple, at least for a brief span of time . The study interviewed 140 couples, both married and unmarried, via questionnaires and surveys . Couples joined the study to gain more knowledge about the state of their romantic affiliation . The researchers measured feelings about the spouse, about their perceived love, spousal trustworthiness, neediness, and parental interference . The couples completed these procedures at a first session, and then around 6 months to a year later, completed identical surveying sessions to see how their relationships have endured the past months . About 80% of the original participants completed the second session . Only a small portion of the original sample had ended their relationships or gotten divorced . In the results of the overall study, there was found to be an increase in love ratings for one's partner and parental interference . Interference did seem to have other frustrating effects, as it also was associated with decreased trust, increased criticalness, and increased frequency of negative, bothersome behaviors . </P> <P> Since the original findings of Driscoll's "the Romeo & Juliet Effect," studies have attempted to find support of the original research . Although no exact replication has been done of the primary study, many researchers have kept on topic regarding relationship interference and relationship stability . </P> <P> In 1983, Malcolm Parks conducted a study to determine influences of peers and families on relationship involvement, which showed little to no support of Driscoll's previous research . Opposition from the partner's family was not associated with greater emotional attachment . These findings set the path for many other studies on romantic involvement and support systems involvement and approval . </P> <P> In recent years, much focus has been placed around the topic of a "Romeo and Juliet Effect ." In 2001, Diane Felmlee found similar findings to Malcolm Park's study . For instance, perceptions of approval from an individual's friends and approval from a partner's family members reduce the possibility that a relationship will end . </P>
