Invisible planning and organizing may feel heavier than visible chores, especially when tasks never seem finished.

Mental load is hard to see. It is still work. This paper links it with distress in women and mothers.

Quick summary

• What the study found: In Mental load in women and mothers: Causes of distress, personality traits, and psychopathology, two cross-sectional online surveys found that mothers perceived invisible planning and organizing as especially stressful and unequal; higher mental load was linked with lower positive affect and higher negative affect, anxiety, and depressive symptoms.
• Why it matters: The burden is not only doing chores. It can include remembering, anticipating, scheduling, and feeling responsible for tasks that other people may not notice.
• What to be careful about: These surveys show associations, not cause and effect. Online recruitment also limits how far the findings can be generalized.

Invisible tasks carried a distinct burden

The paper separates visible work, such as household and caregiving tasks people can observe, from invisible work, such as planning, organizing, and keeping track.

In Study 1, 368 women took part. Mothers reported invisible tasks as significantly more stressful and more unequally distributed than visible tasks.

Across both studies, the most common reasons were constantly thinking about tasks and feeling that tasks never appear to be completed. This is the mental equivalent of tabs left open in a browser.

The emotional pattern was not neutral

Higher mental load was significantly linked with lower positive affect. Positive affect means pleasant emotional states, such as feeling interested or upbeat.

It was also linked with higher negative affect, anxiety, and depressive symptoms. The paper does not show that mental load caused these symptoms.

The safer reading is that heavy invisible responsibility and poorer mood tended to travel together in these survey data. That matters because people often dismiss planning as small.

Why the unfinished feeling matters at home

Visible chores can end. A sink gets cleared. A school form gets submitted. Mental load often restarts as soon as the next need appears. The paper’s framing makes that contrast explicit.

That makes the study’s never completed theme important. The strain may come not only from doing tasks, but from keeping a running inventory of them.

For couples and families, this points to a practical distinction: sharing execution is not the same as sharing anticipation, reminders, and decisions.

A safer way to talk about personality

Study 2 surveyed 1,891 mothers. This larger sample focused on mothers. Mental load was positively related to neuroticism and conscientiousness.

Neuroticism refers to a tendency toward emotional sensitivity or distress. Conscientiousness refers to being organized, dutiful, and careful with responsibilities.

These traits should not be read as blame. The link between mental load and neuroticism was moderated by being a single mother, meaning the association differed by single-mother status.

What remains unclear

The evidence is useful but limited. Both studies were cross-sectional online surveys, so timing and direction are unclear. No intervention was tested.

Participants were recruited through university mailing lists, social media, and parent forums. That may limit how widely the findings apply.

The careful takeaway is simple: invisible household and caregiving work deserves to be counted, especially when it is constant, unequal, and emotionally draining.
