New Jersey Mental-Health Statistics: Prevalence, Access, and Co-Occurring Needs
New Jersey mental-health statistics separate lifetime diagnoses, current screening results, treatment use, county indicators, and co-occurring substance use so unlike measures are not presented as one prevalence rate.

New Jersey mental-health data distinguish lifetime diagnoses, current screening results, treatment use, and county indicators. These measures answer different questions. A positive screen is not a diagnosis, a county prevalence estimate is not a provider count, and treatment use does not prove that care was timely or clinically appropriate.
What did the 2023 New Jersey adult mental-health survey find?
The state survey found that 23.3% of adults reported at least one lifetime mental-health diagnosis, 11.4% screened positive for current anxiety, and 8.7% screened positive for current depression. The survey also identified moderate or severe psychological distress in 9.0%, suicidal thoughts during the prior year in 3.8%, and a suicide attempt in 0.6% of respondents.
Rutgers-Robert Wood Johnson Medical School collected 22,200 responses from October 2022 through August 2023 for DMHAS. Lifetime diagnosis estimates asked whether a medical professional had diagnosed a condition. Current symptom estimates used the PHQ-4 screening instrument, which combines two anxiety items and two depression items covering the prior two weeks.
| Measure | Estimate | Time frame |
|---|---|---|
| At least one professional diagnosis | 23.3% | Lifetime |
| Positive anxiety screen | 11.4% | Prior two weeks |
| Positive depression screen | 8.7% | Prior two weeks |
| Moderate or severe distress | 9.0% | Prior two weeks |
| Suicidal thoughts | 3.8% | Prior 12 months |
| Suicide attempt | 0.6% | Prior 12 months |

- Lifetime diagnosis: whether a medical professional had ever diagnosed the respondent with a named condition.
- Positive anxiety or depression screen: whether recent PHQ-4 responses met the survey threshold for follow-up.
- Psychological distress: the combined PHQ-4 score, categorized separately from either subscale.
- Suicidal thoughts or attempts: self-reported events during the prior 12 months, not a prediction of future behavior.
How do New Jersey county mental-health indicators differ?
NJSHAD's 2021–2023 county depression indicator estimates the age-adjusted percentage of adults ever told by a health professional that they had a depressive disorder. It does not measure current symptoms, severity, treatment need, or the number of available appointments. County comparisons should retain the survey question, date range, denominator, and confidence interval.
Differences between counties can reflect population age, survey response, health-care access, and diagnosis history. A point estimate with a wide confidence interval does not establish that one county has a meaningfully higher prevalence than another.
What do New Jersey youth mental-health statistics measure?
Youth reports use age- and setting-specific measures, so they cannot be generalized to all New Jersey children or adults. Emergency-department diagnosis shares describe visits, while school surveys describe responding students and screening results. Each denominator must remain attached to the statistic.

What does the survey show about mental-health treatment access?
In the 2023 survey, 15.9% of all adults reported mental-health treatment during the prior year, compared with 44.3% of adults screening with moderate or severe distress and 54.8% of adults reporting a lifetime diagnosis. Treatment included reported mental-health services during the survey period; the percentages do not measure appointment availability, clinical fit, or treatment quality.
Among adults with moderate or severe distress, reported past-year treatment varied by race and ethnicity, education, employment, and income. DMHAS also lists crisis services, outpatient programs, case management, supportive housing, supported employment, and other community resources. Safety, symptoms, functioning, medical needs, and available support determine the appropriate route.
Adults whose symptoms interfere with work, relationships, sleep, or basic functioning can receive a clinical evaluation through outpatient mental-health treatment in New Jersey when emergency or inpatient care is not required.

How are mental health and substance use related in New Jersey?
In the same state survey, adults with moderate or severe distress screened positive for alcohol abuse or dependence at 10.2% versus 2.9% among adults with normal or mild distress. Drug abuse or dependence screens were 7.4% versus 1.3%. These associations do not prove that one condition caused the other.

An assessment should examine timing, withdrawal, prescribed medication, trauma, mood, anxiety, sleep, safety, and functioning across both domains. When stable adults have interacting psychiatric and substance-use needs, integrated dual-diagnosis treatment addresses both conditions in one plan. Immediate danger, inability to maintain safety, or a suspected overdose requires emergency help instead.
Frequently asked questions
Does a positive PHQ-4 screen mean someone has a diagnosis?
No. A positive screen identifies recent symptoms that warrant further evaluation; a licensed clinician establishes a diagnosis using a broader assessment.
Can county statistics identify the county with the greatest need?
Not by themselves. County indicators need context about population, survey methods, access, and uncertainty.
Does treatment utilization prove that care was available when needed?
No. A reported treatment encounter does not measure wait time, eligibility, modality, insurance coverage, continuity, or clinical fit.
