Study: Oppositional Defiant Disorder, ADHD Tied to Unemployment, Income Disparities
Young adults with comorbid ADHD and ODD are more likely to be unemployed, take sick days, and earn less than their neurotypical peers, suggests new research from Finland.

Adolescents exhibiting comorbid ADHD and ODD (oppositional defiant disorder) symptoms face higher unemployment rates, sick days, and lower incomes in adulthood than do their neurotypical peers, suggests new research from Finland. 1
The longitudinal study, published in the Journal of Attention Disorders, identified 6,985 participants (aged 15 to 16) from the Northern Finland Birth Cohort 1986. 2 The researchers sorted participants into groups based on symptom presentation — ADHD, ODD, comorbid ADHD and ODD, or the control group. Researchers analyzed sick and unemployed days from 2006 to 2010 (when participants were 20 to 24 years old) and from 2011 to 2019 (when participants were 25 to 33).
Between the ages of 25 and 33, males from all symptomatic groups experienced more unemployment and sick days than did their neurotypical peers, but those symptoms did not directly impact their income levels. During the same age range, females with symptoms of ADHD and comorbid ADHD and ODD reported higher rates of unemployment. However, the study found that younger females (between the ages of 20 and 24) among all symptomatic groups were likelier to report sick days than the controls. (The study did not include participants identified as non-binary or transgender.)
The researchers pointed to previous studies suggesting that “symptoms of ODD and ADHD are associated with substance use disorder, different types of injuries, and an increased risk of undergoing psychiatric hospitalization during one’s life” as likely causes of increased sick leave from work. 3, 4, 5
The ADHD-ODD Link
ODD is highly comorbid with ADHD. Studies estimate that ODD co-occurs with ADHD in approximately 50% to 60% of population-based samples. 6, 7
“Oppositional defiant disorder is characterized by persistent patterns of anger and irritability, argumentative behaviors, and vindictiveness toward others,” said William Dodson, M.D., LF-APA, during the 2021 ADDitude webinar, “How Oppositional Defiant Disorder Ruptures Families — and How You Can Learn to Manage It.” “ODD is listed as a childhood disorder, but it commonly persists into adult life and continues to be highly impairing with symptoms impacting a person’s functioning and causing significant distress to family, friends, and educators.”
Income Disparities
The study also identified income disparities among the study participants. Male and female participants with comorbid ADHD and ODD consistently had lower annual incomes compared to all other symptomatic groups. Interestingly, participants with ADHD reportedly earned more than the control group between the ages of 20 and 24. Those results flipped by age 30.
“Young adults with ADHD symptoms tend to enter the labor market more quickly than their peers without ADHD symptoms, potentially explaining these results,” the researchers wrote. “Individuals without ADHD typically delay entering the workforce at 20 years of age, as they often pursue higher education.”
The results of a 2020 ADDitude survey of nearly 1,450 adults with ADHD painted a slightly different picture. Almost one-third of respondents had an annual household income of $100,000 or higher, and more than half exceeded the U.S. median income ($74,580 in 2022). Though some studies do indicate that young adults with ADHD are less likely to enroll in college, 72% of respondents completed an undergraduate degree, and more than one-third have an advanced degree.
To the researchers’ knowledge, this was the first study underscoring the importance of early recognition of ADHD and oppositional defiant disorder symptoms due to their long-term impact on employment and income in adulthood.
Many ADDitude readers said in a recent survey that they relate to the study’s results.
“I spent a lifetime failing at every job I ever tried,” said Lester, from Idaho. “I was either fired, lost interest, or was injured and had to quit.”
“I am currently unemployed and looking for gainful employment,” said Lindsey, from Indiana. “I’m a single mom with ADHD, and my kids have it, too. I had to work part-time and stay home with my kids for a few years. Now it’s harder than ever to get hired since I took time off.”
Natalie, from Texas, said, “I have had a hard time holding down a job due to my inconsistent attendance and performance. I have been driving for Uber and Lyft for the last few years. It worked out on the first year, but now I’m drowning because I have zero motivation.”
Accommodating ADHD and ODD in the Workplace
Early diagnosis and treatment of ADHD and ODD symptoms during adolescence may improve employment prospects and financial stability later in life.
It also helps when employers foster more inclusive and supportive workplace environments.
“There is plenty that companies can do right now — from shifting perspectives to changing workplace policies — to support neurodivergent employees and those with invisible differences,” said Jessica Hicksted, Ph.D., said during the 2023 ADDitude webinar “Invisible’ Disabilities at Work: How to Foster Neurodivergent Advocacy and Acceptance.”
“All employees benefit when a company embraces multiple methods and processes for getting things done,” she continued. “Whether it’s allowing employee-set schedules, remote work, or non-disruptive changes to the office environment, flexibility can make or break an employee’s experience. A company culture built on flexibility can allow neurodivergent employees to really shine and get work done without battling standards that don’t consider the non-neurotypical experience.”
