Accurate perception of partner behaviour is critical for relationship stability

ILLINOIS: Married couples and long-term love partners often engage in a variety of behaviours that help to sustain and nourish the relationship. These activities encourage increased levels of commitment, which benefits both the physical and psychological well-being of couples.

A recent study from the University of Illinois at Urbana-Champaign analyses the association between such relationship maintenance practices and satisfaction and commitment.

"Relationship maintenance is a well-established measure of couple behaviour. In our study, we measured it with five main categories, which are positivity, openness, assurances, use of social networks, and sharing tasks," said Yifan Hu, a doctoral student in the department of Human Development and Family Studies (HDFS), part of the College of Agricultural, Consumer and Environmental Sciences at U of I.

"Relationship maintenance is usually studied on an individual level. However two partners work together to maintain the relationship. Each person contributes, and each person also perceives the efforts their partner is making. We wanted to look at both individual and interactive (or couple-level) relationship processes," she added.

The researchers analyzed data from 192 heterosexual married couples. Each partner completed an online survey separately. Participants reported their own relationship maintenance behaviours over the past two weeks, as well as their perception of their partner's behaviours.

The surveys also included questions measuring relationship satisfaction and commitment. The results contained some unexpected findings, as there were few direct effects of relationship maintenance behaviours on commitment.

However, relationship satisfaction appeared as a moderating factor between relationship maintenance and commitment. In other words, higher levels of satisfaction led to a more positive assessment of the partner's behaviour, which strengthened commitment.

"Generally, we found people were relatively accurate about their partner's maintenance behaviours. We also found that it is better to have an accurate perception when you are highly satisfied. If you are less satisfied, accurately perceiving your partner's efforts may not be positive. And your partner's accuracy in perceiving your behaviour may make you feel worse because they are aware you may not be doing that much for the relationship," Hu said.

"When a stressful event happens, a couple that is less satisfied with each other may be more likely to react negatively than a couple with higher relationship satisfaction," she added.

Another unexpected finding was that similarity in relationship maintenance behaviours was negatively correlated with wives' level of commitment. Studies have shown that similarity in personality traits, values, and attitudes enhances relationship satisfaction. However, for relationship maintenance strategies, complementary approaches may be more beneficial.

"We found that similarity in behaviours might not be helpful for promoting interactive relationship maintenance. A possible explanation could be that if partners are too similar in their approach, they have a smaller repertoire of coping behaviours," Hu explained.

"When partners are dealing with stressors, they need to work in concert, but using different strategies may be helpful. For example, one partner can use positivity and assurances, while the other can use social networks. They can be mindful of trying to have a larger skill set for relationship maintenance behaviours," she suggested.

Brian Ogolsky, a professor in HDFS, is a co-author of the paper. "Our study aligns with existing literature showing that relationship maintenance enactment and satisfaction are related to commitment," he said.

"At the same time, we found that most relationship maintenance processes at the individual level are associated with commitment only when moderated by satisfaction, which underscores the complexity of couple dynamics."
