Brief summary

Australia is the thirteenth largest contributor of household waste per capita in the world (Organisation for Economic Co-operation and Development, 2022), spending over $10.5 billion annually on goods and services that are never or rarely used (Australia Institute, 2005). This wasteful behaviour contributes to costly landfills, environmental degradation, and rising household debt. Given society’s overconsumption, a handful of commercial programs currently exist to help people strive for minimalism and to declutter their homes. To the best of our knowledge, none of these commercial programs have been scientifically evaluated to see if they actually work, although many testimonials regarding their effectiveness can be found on the Internet. Thus, there is a clear need to develop an evidence base for such interventions. The purpose of this study is to investigate the effectiveness of a new online educational course that was developed to help people buy and save fewer possession in order to save money, reduce clutter, and safeguard the planet. This new course, Breaking up with Belongings, is based on scientific research regarding object attachment, possession ownership, and behaviour change. The course is self-paced and comprised of 6 hours of content (videos plus workbook activities). Eligible participants will be randomly assigned to receive this program immediately or after a three month delay. We ask that participants complete the course within 7 weeks of receiving it, so that they can spend the rest of their time working toward reaching the goal(s) they set during the course. Participants are assessed at baseline and three months later. We expect that those who recieve the Breaking up with Belongings course immediately will report greater improvements than those who receive access to it after a three month delay.

Interventions

Breaking up with Belongings is a novel online, self-guided educational course that consists of 24 videos narrated by an avatar. The online videos are accompanied by an online workbook that can be completed from one’s computer. The videos range in length from 3–16 minutes, for approximately 4 hours of content. Completion of the workbook activities will take at least another two hours. Participants will have access to the course for 3 months so that they can complete the videos and workbooks at th

Breaking up with Belongings is a novel online, self-guided educational course that consists of 24 videos narrated by an avatar. The online videos are accompanied by an online workbook that can be completed from one’s computer. The videos range in length from 3–16 minutes, for approximately 4 hours of content. Completion of the workbook activities will take at least another two hours. Participants will have access to the course for 3 months so that they can complete the videos and workbooks at their discretion. However, participatns will be asked to complete the course within 7 weeks so that they can spend the remainder of their time in the trial working toward the goal(s) they set. The course begins by asking participants to think about what they hope to accomplish and why. It then instructs participants about the causes and consequences of object attachment and teaches them how to manage their emotions, so that they will be better able to resist buying and saving unnecessary belongings. The course assists participants in setting a smart goal and in developing a plan that will help them reach that goal. Throughout the course, various characters are introduced that have acquiring and saving difficulties to show participants how to carry out suggested techniques. The workbook is used to log the activities mentioned in the videos (i.e., the workbook does not provide new information). To understand how to complete the workbook, participants need to watch the videos. This course is new and is not currently available outside of this research study. Adherence will be assessed by using available website data on the number of videos completed by each participant, as well as the time spent on the website.
