The language of people helping people

plain-language definitions of the words behind peer support. no jargon, no medical gatekeeping — just what these terms actually mean and why they matter when you’re looking for somewhere to put it.

What is peer support?

Peer support is emotional and practical help exchanged between people who share lived experience of a problem, rather than help delivered by a clinician to a patient.

What is emotional support?

Emotional support is the experience of being heard, validated, and accompanied by another person in a feeling — as distinct from being advised, fixed, or evaluated.

What is a support group?

A support group is a set of people who meet regularly to share experience and encouragement around a common struggle, usually without a clinician directing treatment.

What is active listening?

Active listening is attending fully to another person to understand their meaning and feeling — reflecting it back — rather than listening only to prepare your reply.

What is social isolation?

Social isolation is an objective shortage of social contact and relationships — distinct from loneliness, which is the subjective feeling of lacking connection.

What is co-regulation?

Co-regulation is the process of settling your own nervous system through connection with another calm, present person — the interpersonal basis of emotional regulation.

What is mutual aid?

Mutual aid is a form of voluntary, reciprocal exchange of resources and support among people, organized on the principle of solidarity rather than top-down charity.

What is anonymous support?

Anonymous support is emotional or practical help exchanged without participants revealing their real-world identity, lowering the social cost of honesty.

Boxed warning (black box warning)

The FDA's strongest label warning — text in a black border at the top of a drug's prescribing information, reserved for risks that are serious or life-threatening.

Off-label use

Prescribing an approved drug for a condition, dose, or age group the FDA never approved it for — legal for doctors, illegal for manufacturers to promote.

Discontinuation syndrome

The physical and psychological symptoms that can follow stopping or rapidly reducing an antidepressant — real, common with abrupt stops, and not the same thing as relapse or addiction.

Half-life

The time it takes your body to eliminate half of a drug — the single number that best predicts how hard a drug is to stop abruptly.

Pivotal trial

The clinical trials a drug approval actually rests on — usually short, placebo-controlled, and much briefer than real-world use.

Open-label extension

A follow-on study where trial participants keep taking the drug with everyone knowing it — useful for safety data, weak for proving long-term benefit.

Effect size

How big a difference a treatment actually makes, on a standard scale — the number that separates statistically significant from worth taking.

Number needed to treat (NNT)

How many people must take a treatment for one additional person to benefit versus placebo — the most honest single number in medicine.

Placebo response

The improvement people show on the inert comparator in trials — large in depression studies, and the reason 'I felt better on it' and 'it works better than placebo' are different claims.

FAERS (FDA adverse event reporting system)

The FDA's public database of side-effect reports — invaluable for detecting signals, useless for calculating how often anything happens.

Bioequivalence

The standard a generic must meet — releasing the same drug into the blood at the same rate and extent as the brand. usually true; famously, once, not.

Recall classes (class I, II, III)

The FDA's severity scale for drug recalls: class I means reasonable probability of serious harm or death; most recalls are routine class II quality issues.

MDL (multidistrict litigation)

The federal system that gathers similar lawsuits from around the country before one judge for pretrial work — how most drug injury cases are actually processed.

Bellwether trial

A test case tried early in mass litigation so both sides can see how juries react — a pricing mechanism, not a final answer.

Settled vs. adjudicated

The distinction this entire library is built on: a settlement resolves claims without deciding them; only adjudication decides anything.

Dual-eligible (medicare under 65)

People on medicare before age 65 — there through disability, often also on medicaid, among the sickest populations in american healthcare, and not a stand-in for ordinary adults.

Pay-for-delay

A settlement where a brand manufacturer compensates a generic maker to stay off the market — every refill during the delay is bought at brand prices.

REMS (risk evaluation and mitigation strategy)

A restriction program the FDA can attach to a drug whose risks need more active management than label warnings — certified prescribers or pharmacies, mandatory monitoring, or restricted settings of use.

Relative vs absolute risk

Relative risk compares two rates as a ratio ("twice the risk"); absolute risk states the actual difference ("from 1% to 2%"). The same result can sound alarming in one form and modest in the other.

Intention-to-treat vs per-protocol

Intention-to-treat analyzes everyone as randomized, whether or not they completed treatment; per-protocol analyzes only those who did. ITT preserves the fairness of randomization; per-protocol answers a different, easier question.

Wait-list control

A control condition in which the comparison group receives usual care while waiting to get the intervention after the trial — common where a placebo is impossible, and known to produce larger apparent effects than active controls.

Warning letter (FDA)

A formal, public FDA notice that the agency believes a company violated the law — a demand to correct, not a court finding, sitting above an untitled letter and below enforcement action.

Complete response letter (CRL)

The FDA's formal notice that it will not approve a drug application in its current form, listing the deficiencies a resubmission must address.

Sentinel surveillance

A monitoring design that collects detailed data from a selected network of sites and projects national estimates from them — faster and richer than a census, and only as representative as the network.

Survey response rate

The share of people invited to a survey who actually completed it. As it falls, the risk grows that responders differ from non-responders in ways that bend the results — nonresponse bias.

Confidence interval

The range published around a study estimate expressing its statistical precision — a 95% CI is the range that would contain the true value in 95% of identical repeated studies.
