According to a study published in the Journal of Personality & Social Psychology, relationship satisfaction declines more sharply in relationships that eventually dissolve compared to those that continue, and individuals tend to report higher satisfaction when entering a new relationship, though satisfaction declines over time in both new and previous relationships.
Romantic relationships are fundamental to well-being. Most studies have focused on younger adults and short-term relationships, leaving a gap in understanding how satisfaction changes across the full life course, particularly in long-term relationships or those that transition into new partnerships.
Janina Larissa Bühler and Ulrich Orth analyzed data from the Longitudinal Study of Generations, which included 2,268 participants aged 16-90 years, assessed up to seven times over 20 years. Participants reported their relationship status at each wave of data collection, which enabled the researchers to classify them into three primary groups: those in long-term continuing relationships, those in relationships that eventually dissolved, and those who repartnered after a breakup.
Participants completed the 10-item Gilford-Bengtson Marital Satisfaction Scale, which measures both positive and negative aspects of romantic relationships. The scale captures key dimensions of relationship quality, including frequency of positive interactions, disagreements, and overall contentment with the partnership. Additional variables such as age, gender, presence of children, and relationship duration were examined to identify moderating factors influencing satisfaction trends.
Relationship satisfaction followed distinct trajectories depending on whether a relationship endured, dissolved, or was followed by a new partnership.
In relationships that remained intact, satisfaction tended to decline modestly over time but remained relatively stable overall. In contrast, relationships that ultimately ended showed significantly lower levels of satisfaction from the outset and exhibited a sharper decline over time. Notably, couples with children experienced steeper declines in satisfaction, and those in shorter relationships that ended reported particularly pronounced drops in contentment.
For individuals who entered a new relationship following a breakup, relationship satisfaction rebounded initially, with participants reporting significantly higher satisfaction at the beginning of a new relationship compared to the start of their previous one. However, despite this initial boost, satisfaction once again declined as the relationship progressed, mirroring the pattern observed in earlier partnerships. This suggests that while new relationships may offer temporary improvements in happiness, they are still subject to the same long-term declines that characterize romantic relationships more broadly.
Additionally, individuals who moved into a new relationship quickly after a breakup reported lower overall satisfaction compared to those who took more time before repartnering, indicating that a shorter transition period may not necessarily lead to a more fulfilling romantic experience.
This study relied on self-reported relationship satisfaction, which may be influenced by retrospective bias. Additionally, the sample primarily consisted of White, middle-class families, potentially limiting generalizability to more diverse populations.
