This study explored the factor structure of perceptions of love and sex in a Portuguese sample throughout the adult life span. A total of 924 men and women (52% women) participated, all of whom were currently in a romantic relationship. The Perceptions of Love and Sex Scale showed the same four-factor structure that was evidenced in U.S. samples, and acceptable psychometric properties. Age and gender influenced these perceptions of love and sex. Expected correlations with measures of other relationship constructs were found. <\/jats:p>","DOI":"10.1177\/0265407512443638","type":"journal-article","created":{"date-parts":[[2012,5,1]],"date-time":"2012-05-01T01:50:29Z","timestamp":1335837029000},"page":"760-775","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":25,"title":["Perceptions of love and sex across the adult life span"],"prefix":"10.1177","volume":"29","author":[{"given":"F\u00e9lix","family":"Neto","sequence":"first","affiliation":[{"name":"Universidade do Porto, Portugal"}]}],"member":"179","published-online":{"date-parts":[[2012,4,30]]},"reference":[{"key":"bibr1-0265407512443638","doi-asserted-by":"publisher","DOI":"10.1037\/0003-066X.54.5.317"},{"key":"bibr2-0265407512443638","first-page":"25","volume-title":"Sexuality in close relationships","author":"Aron A.","year":"1991"},{"key":"bibr3-0265407512443638","first-page":"359","volume-title":"The psychology of love","author":"Berscheid E.","year":"1988"},{"key":"bibr4-0265407512443638","first-page":"349","volume-title":"Understanding culture\u2019s influence on behaviour","author":"Brislin R.
