Acevedo and co-researcher Arthur Aron, PhD, reviewed 25 studies with 6,070 individuals in short- and long-term relationships to find out whether romantic love is associated with more satisfaction. To determine this, they classified the relationships in each of the studies as romantic, passionate (romantic with obsession) or friendship-like love and categorized them as long- or short-term.

Acevedo和研究合作者Arthur Aron博士回顧了以往的25項研究（它們的研究對象總共包括6070個處于短期或長期關系中的人），以檢驗浪漫愛情是否與更高的滿意度相聯系。為了證實這一點，他們把每項研究中的愛情關系歸類為浪漫的、激情的（浪漫加上強迫成分）和友誼式的，再分為長期和短期關系兩類。

The researchers looked at 17 short-term relationship studies, which included 18- to 23-year-old college students who were single, dating or married, with the average relationship lasting less than four years. They also looked at 10 long-term relationship studies comprising middle-aged couples who were typically married 10 years or more. Two of the studies included both long- and short-term relationships in which it was possible to distinguish the two samples.

研究者查看了17個對于短期關系的研究，其對象包括18-23歲的單身、戀愛中或已婚的大學生，他們愛情關系的平均持續時間在四年以下。還有10個對于長期關系的研究，其對象包括結婚10年或更久的中年夫婦。其中兩個研究同時包括了短期和長期關系，這兩組樣本是區分開來的。
