The short answer
Before acting on mental health advice you find online, check who wrote it, who reviewed it, and who it was written for. A page written for the general public reads very differently from one written for clinicians or for people with a specific diagnosis. Look for an “About Us” page, a named organization or reviewer, and a stated audience or update date before deciding whether the advice applies to you.
Terms to know
- Audience: the group of readers a piece of content is written for — for example, the general public, caregivers, teenagers, or medical professionals. Advice written for one audience may not fit another.
- Source: the organization or person responsible for the content, as opposed to a website that simply republishes or links to it.
- Editorial review: a process where someone with relevant expertise checks content for accuracy before it is published, separate from the person who originally wrote it.
- Population-level information: facts about a large group (for example, “970 million people globally live with a mental disorder,” according to the World Health Organization) as opposed to information about what is true for any one individual.
Why “who it was written for” matters as much as “who wrote it”
According to the National Library of Medicine's MedlinePlus, evaluating health information starts with asking who runs the site, what its purpose is, and who pays for it — because a trustworthy source has one goal: giving accurate information, not selling something or promoting a particular opinion. That same guidance applies directly to mental health content, but there's a second question worth adding: who was this specific piece written for?
A statistic or recommendation aimed at a general audience is often written differently than one aimed at people already diagnosed with a specific condition, or at parents, or at clinicians. The World Health Organization notes that population-level facts — for example, that mental disorders account for roughly 1 in 6 years lived with disability worldwide — describe patterns across large groups. They are not a description of what any one person should expect or do. Content that blurs this line, applying a broad population statistic as if it were personal guidance, is a sign the piece may not have been written carefully for the audience actually reading it.
Comparing common source types
Not all sources publish the same way or for the same reason. Here is how MedlinePlus's evaluation criteria generally map onto the kinds of sites you'll run into when searching for mental health information:
- Federal agencies and medical schools (such as the National Institute of Mental Health or a university health system): MedlinePlus notes these are generally reliable, typically state their purpose clearly, and usually show a review or update date.
- Large nonprofit or professional organizations (such as a national mental health association): often reliable, but check for a named editorial board or review process on their “About Us” page, since not every nonprofit publishes the same way.
- Commercial sites that sell a product or service: MedlinePlus specifically flags that if a business pays for the site, the information may favor that business's own products, so read any claims with that in mind.
- Individual blogs or social media accounts: MedlinePlus points out that a post coming from someone you know is not the same as a reviewed, sourced piece — ask where the information originally came from and why it was posted before treating it as guidance.
The audience-and-source checklist
Use these questions, adapted from MedlinePlus's framework for evaluating health information, before you rely on anything you read about mental health online:
- Who runs the site? Look for an “About Us” page. If you can't find who is responsible for the content, treat the information with caution.
- Who was it written for? Does the piece say, or clearly imply, its intended audience — general readers, people with a specific diagnosis, caregivers, or professionals? If you can't tell, the advice may not be calibrated for your situation.
- What's the purpose? Is the goal to inform, or to sell a product, service, or opinion?
- Who pays for it? If ads or a business fund the site, MedlinePlus advises watching for information that favors that business's own products.
- Is it reviewed? Look for an editorial board, a stated review process, or information about the writer's qualifications.
- Is it current? Check for a “last reviewed” or “last updated” date. Mental health guidance can change as research develops, so undated content is harder to trust.
- Does it match other reliable sources? MedlinePlus recommends checking whether other trustworthy sites say something similar before relying on any single page.
What stays uncertain, and what to do next
Even a well-sourced, clearly-audienced page cannot tell you what applies to your specific situation. General guidance and population statistics describe patterns across large groups, not individual outcomes. MedlinePlus's own advice, after evaluating a source, is to discuss what you found with a health care provider before using it to make decisions about your health — the source can tell you whether information is well-supported, but a provider is better placed to tell you whether it applies to you.
