Psychologists at the University of New England are seeking more than 100 participants for a study that will test ways of making people happier and more satisfied with their romantic relationships.
Psychology honours student Michelle Janus said she was looking for people who might be mildly dissatisfied with their relationship, as well as those who might "simply be looking to improve what is already a good situation".
Participants need to be over 18 and currently in a romantic relationship. They can either take part in the study individually or as a couple. People in same-sex relationships as well as those in heterosexual relationships are welcome to apply.
Participation will involve filling in a short questionnaire and completing a 10-day online training course for 10 minutes a day.
Building healthy, satisfying relationships was extremely important for individual well-being, as well as having a positive impact on society at large, Ms Janus said.
"Working in children's services, I too often see the result of what happens when relationships break down," Ms Janus said. "I hope that findings from my study could help to develop a course to get couples on the right track before problems arise."
Dr John Malouff, the UNE associate professor in psychology who is supervising Ms Janus's research, said that because romantic relationships played such a large part in people's lives, finding ways to improve them was an important line of enquiry for psychological research.
"If you're feeling crummy about your romantic relationship, that can have a flow-on effect on your physical and mental health, your performance at work, and so on.
"Studies such as this are helping us to develop simple, cost-effective interventions that can help people improve the quality of their relationships and become happier and more satisfied in general."
