A new study finds that mental-health responses to repeated adversity vary by event type, challenging the idea that hardship automatically builds resilience.
On October 19, 2026, researchers from the University of Sydney published a study in Psychological Medicine that found no universal pattern in how mental health responds to repeated adversity.
The central finding is that going through something difficult again does not reliably produce the same psychological response across different kinds of hardship. Some repeated events were associated with a larger negative mental-health effect. Others were associated with a smaller effect. Several showed no clear pattern.
That challenges the assumption that experience automatically makes a person tougher. It also challenges the opposite assumption that every additional hardship must have an increasingly damaging effect. The findings point away from a single rule and toward a more context-sensitive understanding of repeated adversity.
For someone managing sustained strain in midlife, that distinction matters. Having faced a difficulty before is not a sound basis for expecting a particular response the next time.
Alexander Chye and colleagues analyzed data from the Household, Income and Labour Dynamics in Australia panel, known as HILDA. The data covered 2001 through 2023 and included 35,594 adults. Of those participants, 23,109 had experienced at least one of the seven adverse events examined.
The researchers followed mental-health responses across repeated occurrences within each event category. Those categories were:
The outcome was the Mental Health Inventory-5, or MHI-5. This five-item questionnaire measures depression and anxiety symptoms on a scale from 0 to 100. Higher scores indicate better mental health.
According to the study, all seven event types were associated with significant negative mental-health effects when they occurred. The difference lay in what happened when people reported the same category of adversity again.
The authors described two patterns that appeared for some event types: sensitisation and habituation. These terms refer to the relative size of the measured response across repeated exposures.
For several event types, the effects appeared to plateau after the second occurrence. They did not keep becoming progressively stronger with every additional event. A plateau describes the pattern across occurrences; it does not mean that the event had become harmless.
The researchers also examined cumulative exposure. More exposure was associated with lower MHI-5 scores. For several event types, that relationship weakened after the analysis accounted for mental health before the event and differences between people.
Together, these findings make a simple hardship tally an incomplete way to understand mental health. The number of events was part of the picture, but it was not a universal explanation for the response.
This was an observational study. It identified associations rather than establishing that repeated adversity caused the measured changes. The MHI-5 is not a diagnosis of a specific disorder or a direct assessment of resilience mechanisms.
The authors also warn against treating habituation as proof of healthy adaptation. A smaller measured response could reflect emotional numbing rather than resilience or personal growth. Less visible distress and greater psychological strength are not interchangeable conclusions.
The researchers could not measure or control for the severity of each event. Experiences within the same category could differ substantially. They also could not directly measure personal meaning or coping responses. Resources and other resilience mechanisms were not directly measured either.
Some comparisons had limited statistical power. This applied particularly to job loss and physical violence, plus the comparison involving property crime experienced twice. The authors advise treating non-significant results as inconclusive rather than evidence of no effect.
Reports in consecutive years could sometimes describe one continuing event rather than separate events. When the researchers excluded consecutive-year reports in a sensitivity analysis, some patterns changed. The Australian adult sample also does not directly establish whether the findings apply to other countries or cultural and socioeconomic settings.
Finally, the paper examined mental-health symptoms after adverse events. It did not test stress-management techniques or treatments. Nor did it assess sleep interventions or show which actions improve recovery.
For an adult aged 35 to 65, the most defensible daily adjustment is a change in self-assessment: stop using previous exposure as a benchmark for how well a current difficulty should be handled.
A familiar thought might be: I have dealt with this before, so why is it affecting me now? The study gives a reason to question the expectation inside that sentence. Repetition did not produce one consistent mental-health pattern across the events examined.
A more proportionate daily question is: What is difficult about the situation I am facing now? This keeps attention on the present experience rather than turning past hardship into a test that must be passed again. It is an editorial application of the finding, not a clinical protocol.
The distinction is practical. When reflecting on a hard day, an adult does not need to decide whether the experience proves strength or weakness. The immediate task can be to describe the strain without assigning it a character judgment.
That might mean recognizing that the current concern involves finances rather than assuming all stress should feel alike. It might mean acknowledging that another illness or separation has its own significance. The study’s event-specific findings support taking those differences seriously without predicting an individual outcome from the group results.
The authors identify personal meaning and available resources as possible parts of the explanation. In everyday reflection, those ideas offer useful questions rather than established answers: What does this event mean in the current circumstances? What support or practical resources are available now?
Those questions should not become another demanding tracking routine. Their purpose here is to replace an unsupported assumption with a more accurate description of the situation. No resilience score is required.
This framing also leaves room for a nonjudgmental conclusion: struggling after repeated difficulties is not evidence of personal failure. A person does not owe anyone a steadily improving response to hardship simply because it has happened before.
Relaxopia’s broader coverage of stress and mental resilience follows that distinction between understanding strain and treating it as a performance problem. Related reading on living with uncertainty offers another place to think about the expectations attached to difficult experiences.
Where decisions concern personal mental-health care, a qualified health professional is the appropriate person to discuss individual options. The study is most useful as a correction to a broad belief about adversity, not as a basis for selecting treatment.
The authors suggest that responses to adversity may depend on context, individual meaning and resources. That points toward a research question more useful than whether hardship makes people stronger in the abstract: which circumstances accompany better outcomes when a similar difficulty happens again?
Future work that directly measures those factors could help clarify why responses differ within the same event category. It could also help researchers distinguish the number of events from the significance of each experience. These are directions for further investigation rather than findings already established by this paper.
For adults in midlife, the immediate value is a less rigid expectation about repeated hardship. Experience is part of a person’s history, not a guarantee about their next response.
Could future research shift long-term approaches to midlife recovery away from counting hardships and toward understanding the circumstances in which people regain their footing?
Interpreting another setback starts with separating lived strain from claims about becoming stronger, a distinction Relaxopia addresses through evidence-based reporting.
