Quick Summary

A new study from the University of Queensland in Scientific Reports examines the concept of “tri-load” in heterosexual relationships, which includes physical, cognitive, and emotional labor associated with managing a home. The research, based on data from 235 couples, reveals that women typically handle significantly more household tasks, particularly the cognitive load such as planning and scheduling, doing almost 25% more than men. Additionally, discrepancies in how partners perceive their contributions to household duties are linked to lower relationship quality.

Story summary

A new study published in Scientific Reports by researchers from the University of Queensland School of Psychology examines the "tri-load" concept in household labor. The tri-load comprises physical chores like cleaning and cooking; cognitive tasks such as planning shopping lists and scheduling appointments; and emotional labor involving anticipation, care, and consolation. Using data from 235 heterosexual couples, the study found that women typically handle up to 67% more household responsibilities than men, which negatively impacts relationship quality. The research highlights that even though societal roles have evolved since sociologist Monique Haicault coined the term "mental load" in the 1970s, women still disproportionately manage domestic duties, leading to stress and reduced relationship satisfaction.

🔮 It’s the kind of home most people would look at and think, “Yes, I’d live here”.
🔮 “By looking at both partners’ perspectives, we were able to examine whether two people in the same relationship may experience and interpret the division of household responsibilities differently, and whether these differences matter for relationship quality,” Coundouris says.
🔮 “Aurelia will always drop me off at the train in the morning, and we’ll have a kiss goodbye, and then she’ll pick me up with our dog, and we have a kiss hello,” Natt, 35, says.
🔮 Max Mara opted to keep things streamlined with a solid, practical leather style, and at Balenciaga, Pierpaolo Piccioli asked: why have one belt when you could wear two?
🔮 It’s where Lady Gaga debuted the meat dress that would become pop culture lore, Lil Kim made the case for purple nipple pasties and where Britney Spears established herself as a chameleon who can pull off a black lace mini dress one minute and a Swarovski-crystal-embellished bodysuit the next.
🔮 This year’s ceremony will see some of the world’s biggest artists go head-to-head, including Gen Z darling Sabrina Carpenter, Kpop sensation BTS, and pop veteran Madonna.
🔮 As the cheap-shot headlines tell you, the dress could have been created by an AI chatbot from a “Brownlow fashion” prompt: the racer back tank style left the sides wide open and left her back exposed, while the splits at the hem allowed for a flash of thigh. But what’s lost here is how great Brown looked.
🔮 Arguably more pressing than the medal recipient though is who will score style points on the carpet.
🔮 I’m Gyan Yankovich, and I’ll be hosting today’s red carpet coverage along with deputy lifestyle editor Courtney Thompson, who will be reporting on all the best looks from the big event.
🔮 The Brownlow is a big night for the AFL, and an even bigger night for the cottage industry of designers, stylists, hair and make-up artists, spray tanners, social media managers and WAGs, who usually only have a few weeks to rustle together a look that will hopefully be remembered for all the right reasons.

Narrative

Assessing the ‘tri-load’ For the study, published in Scientific Reports, researchers from the University of Queensland were interested in the “tri-load” of household labour: physical (traditional chores such as washing, cleaning and cooking); cognitive (planning shopping lists, scheduling appointments); and emotional (anticipating, caring, comforting, consoling).

Claims (35 extracted, 3 hedged)

It’s been over four decades since French sociologist Monique Haicault coined the term “mental load” to describe the dual burden women shoulder when managing their careers and domestic responsibilities. asserted
women → coin → careers
In that time, women have become more educated and make up a greater percentage of the workforce. asserted
women → become → workforce
Despite these social changes, research shows women in heterosexual relationships still manage up to 67 per cent more of the household tasks than their male partners, and a new study has found it can have detrimental consequences for relationship quality. asserted
it → show → quality
Assessing the ‘tri-load’ For the study, published in Scientific Reports, researchers from the University of Queensland were interested in the “tri-load” of household labour: physical (traditional chores such as washing, cleaning and cooking); cognitive (planning shopping lists, scheduling appointments); and emotional (anticipating, caring, comforting, consoling). asserted
researchers → assess → appointments
Using data from 235 heterosexual romantic couples, they examined how the division of labour was related to relationship quality. asserted
division → use → quality
“While this study is not the first to recognise the importance of these mental loads, it is the first to apply a tri-load division of labour,” explains Dr Sarah Coundouris, lead author of the study and research fellow at University of Queensland School of Psychology. asserted
Coundouris → recognise → Psychology
Across all three types of household labour, women reported taking on more work, but the difference was most significant for the cognitive load, with women taking on almost 25 per cent more of the thinking, planning and scheduling involved in running the home than their partners reported. asserted
partners → report → home
“This is a valuable study because it looks well beyond who does the dishes,” says Georgie Dent, chief executive of The Parenthood. asserted
Dent → look → Parenthood
“The idea of the ‘tri-load’ captures the full picture: doing the work, thinking about the work and caring about how everyone is coping. asserted
everyone → capture → work
The cognitive load can be particularly relentless because it is often invisible, and it never really switches off. asserted
it → switch → ?
“The findings echo what parents tell us every day and what the research has shown for decades. asserted
research → echo → decades
Women have moved into paid work in huge numbers, but men have not moved into unpaid work at the same rate. asserted
men → move → rate
What I find telling is that the biggest gap is in the planning and organising. asserted
gap → find → planning
That work is the hardest to see, so it is the easiest to overlook. asserted
it → see → ?
Differences of opinion matter ... asserted
Differences → matter → opinion
Researchers also looked at how differences in opinions about household contributions were linked to relationship quality. asserted
differences → look → quality
“By looking at both partners’ perspectives, we were able to examine whether two people in the same relationship may experience and interpret the division of household responsibilities differently, and whether these differences matter for relationship quality,” Coundouris says. uncertain
Coundouris → look → quality
They found that as the gap between how partners perceived their contributions grew, relationship quality worsened. asserted
quality → find → contributions
For example, pairs who had different opinions about how physical and emotional household duties were shared reported greater unhappiness in the relationship (with this finding strongest for women). asserted
finding → have → women
These conflicts come up regularly for clients of clinical psychologist Narelle Dickinson. asserted
conflicts → come → Dickinson
“This is something I hear being discussed at least once a day in my room,” Dickinson says. asserted
Dickinson → hear → room
“Everyone’s under the pump, everyone’s exhausted and when one person feels like they’re doing so much of that load and the other doesn’t see the differences there – oh my goodness – resentment starts to breed pretty fast.” asserted
resentment → ’ → differences
Interestingly, disparities in the perceived division of cognitive household demands were only linked to poorer relationship quality in men. asserted
disparities → perceive → men
While they can only speculate why it wasn’t linked to poorer relationship quality for women, Coundouris has some theories. asserted
Coundouris → speculate → theories
“It may be that despite women potentially struggling to meet the cognitive load, their relationship quality may not be affected by these different opinions, as expectations are so deeply rooted in what is socially acceptable: women should be responsible for the cognitive load,” she says. uncertain
she → struggle → load
As for why men were negatively affected? “It could possibly be the result of their partners’ voicing their displeasure and/or due to women experiencing poorer health and wellbeing due to the high cognitive load, and this seeping into other dimensions of the relationship.” uncertain
this → affect → relationship
Coundouris hopes that in establishing a connection between the tri-load and relationship quality, the research aids future development of evidence-based guidelines in relationship therapy and enhancing overall health and wellbeing. asserted
research → hop → health
How can couples ensure they share the tri-load? asserted
they → ensure → load
Where the lack of help isn’t a case of weaponised incompetence or abuse, Dickinson says trying to effectively communicate can go a long way. asserted
trying → say → way
“It’s about trying to get each other to see that perspective,” she says. asserted
she → ’ → perspective
“To lean into each other to try share that role a little bit more and figure out how they can communicate better about how they’re feeling, what their energy levels are, what level of load they’re carrying, and see if they can cooperatively come up with some solutions to sharing the load, not necessarily equally, but definitely equitably. asserted
they → lean → load
For families, Dent notes that support also shouldn’t be left to individuals to figure out as policies and workplaces also meaningfully influence how care is shared. asserted
care → note → individuals
“Australia needs 52 weeks of paid parental leave at a replacement wage, with meaningful time reserved for each parent, so both parents become confident and capable carers from the beginning,” she says. asserted
she → need → beginning
“Families also need universal access to high-quality early childhood education and care, and workplaces that genuinely accommodate caring responsibilities. asserted
that → need → responsibilities
It should help families share care, not simply make it easier for women to carry paid and unpaid work at the same time. asserted
women → help → time
