Two months into a new job, your stomach hurts every morning and you can't sleep at night. Things that never bothered you now bring tears, and you wonder if you're the only one who can't adjust. Struggling after a big change is common, but when the struggle is bigger or lasts longer than expected, it may be called adjustment disorder. Here is what it is, how it differs from depression or ordinary stress, and how to work through it.

What does adjustment disorder mean? #

Adjustment disorder is emotional or behavioral difficulty that arises in response to an identifiable stressor, such as a job change, a breakup, a move or an illness. The American Psychiatric Association's DSM-5 describes symptoms that begin within three months of the event, with distress out of proportion to its severity or trouble at work, in relationships or in daily life. It is not used when another mental disorder fits better or for normal grief, and symptoms do not last more than six months after the stressor or its consequences end.

The World Health Organization's ICD-11 frames it a little differently. Symptoms usually start within one month of the event, and the core features are preoccupation with the event and its consequences (rumination, excessive worry, distressing thoughts that keep coming back) and failure to adapt, where sleep or concentration problems make daily life hard to manage. Symptoms are expected to resolve within about six months unless the stressor continues. Studies using newer tools have found a rate of about 2% in the general population, and much higher rates among people who recently lost their jobs (27%) or were bereaved (18%), according to a 2019 review by O'Donnell and colleagues.

Adjustment disorder symptoms: what it can look like #

Adjustment disorder looks different for different people. If several of the following started after the event and have lasted for weeks, it is worth paying attention. A diagnosis is made in a clinical visit.

• Getting stuck on the event: it keeps coming to mind all day, and the same thoughts go around in circles.
• Low mood and tears: you feel down easily and cry for no clear reason.
• Anxiety and tension: small things make you restless, and worries pile up.
• Disrupted sleep and focus: you have trouble falling or staying asleep and can't concentrate on work or study.
• Body signals: stomachaches, headaches or chest tightness before work or school.
• Avoiding or snapping: you dodge messages and put off plans, or you get angry more easily than usual.

Even when these feel like stress, physical symptoms such as pain or shortness of breath can have other causes. If they are new or getting worse, have your body checked first.

How is adjustment disorder different from depression and ordinary stress? #

The three can look alike and are hard to tell apart on your own. Below is a rough guide to what sits at the center of each.

Adjustment disorder is the name used when the criteria for depression are not met. So something that starts as adjustment disorder may later be seen as depression if symptoms deepen and last. In a study that followed 826 seriously injured patients for a year (O'Donnell et al., 2016), 19% had adjustment disorder at three months and 16% at twelve months, and those who had it at three months were more likely to meet criteria for another mental disorder at twelve months. That is a reason to take care of it early rather than brushing it off. If your mood has been low for more than two weeks, see early signs of depression.

Common triggers: a new job, a new school, a breakup, military service #

The trigger is not always a bad event. Even a wanted change, such as a new job, a marriage or a new baby, can leave the mind struggling to catch up when it reshapes daily life. Common triggers include the following.

• Work changes: starting a job, changing jobs, a transfer or promotion, losing a job or a contract ending
• School changes: starting school, transferring, moving up a level, beginning dorm life
• Relationship changes: a breakup or divorce, a serious conflict with someone close, relationships strained by a move
• Military service and discharge: unfamiliar rules and a cut-off life, then returning to civilian life
• Health and life changes: a serious diagnosis, an accident, caring for a family member

If work is the trigger, see work stress relief. If a breakup is the trigger, see recovering after a breakup.

Adjustment disorder treatment: psychotherapy comes first #

The core of treatment for adjustment disorder is psychotherapy. Of the 29 studies gathered in a 2018 systematic review (O'Donnell et al.), more than half tested psychological therapies, and more than half of those included cognitive behavioral therapy (CBT) components. A Cochrane review of workers on sick leave with adjustment disorder (Arends et al., 2012) found that problem-solving therapy shortened the time to partial return to work at one-year follow-up. Treatment research is still limited, and researchers call for more studies.

In counseling, you usually sort out together what feels heaviest right now and separate what can change from what has to be accepted. Problems that can change are broken into small steps and worked through one at a time (problem solving), and you check whether your thoughts about the event are heavier than the facts (CBT). Getting sleep and daily rhythm back on track is part of the work too. Whether medication is needed is decided with a doctor. To learn about different kinds of therapy, see types of psychotherapy.

Five things you can try on your own #

1. Write down what changed: putting a day before and after the change side by side turns a vague weight into a few concrete problems.
2. Pick one thing and make it small: choose one thing you can act on now and shrink it to something doable this week.
3. Keep sleep and meals steady: fixing your wake-up time and mealtimes first gives a shaken day something to hold on to.
4. Set aside worry time: if the event keeps coming to mind, pick a short time each day to think it through, and come back to what you were doing the rest of the day.
5. Ask for support: tell someone you trust, or someone who went through the same change, how you are really doing. Counseling services at school or work are an option too.

For everyday habits that ease built-up tension, see stress relief. For ways to handle thoughts that keep circling, see overthinking.

Medical certificates and workers' compensation in Korea #

A medical certificate for adjustment disorder is issued by the psychiatrist who treated you, based on interviews and how symptoms have developed. Whether it can be used for leave from work or school depends on each workplace's or school's rules, so check in advance. If you are worried about records, see does a psychiatry visit stay on your record.

On workers' compensation in Korea: the Industrial Accident Compensation Insurance Act treats illness caused by work-related mental stress, such as workplace harassment under the Labor Standards Act or verbal abuse from customers, as an occupational illness (Article 37). The Act's Enforcement Decree also lists adjustment disorder or a depressive episode caused by events such as violence or verbal abuse from customers, or stress directly related to them, among its criteria for occupational illness. A substantial causal link between the work and the illness is required, so check the application process and eligibility with the Korea Workers' Compensation and Welfare Service. If you are experiencing harassment, keeping a dated record helps.

How heavy has it been lately? The K10 check #

The CareOps psychological distress check (K10) is not an adjustment disorder test. It is a ten-item check on how heavy things have felt over the past 30 days, not limited to depression or anxiety. You can take it right away, with no login.
