What is gaslighting and what effects does it have on relationship functioning?

• A. Manipulating someone to doubt their reality; undermines self-trust and autonomy, often eroding relationship safety.
• B. Direct physical assault causing fear.
• C. Healthy form of reassurance.
• D. Strengthens autonomy.

Answer: (A)

Gaslighting is a manipulative pattern where one partner tries to make the other doubt their own perceptions, memories, or sanity. It’s an intentional distortion of reality, so the other person second-guesses what they saw, felt, or recall. As this behavior repeats, self-trust and autonomy crumble because the person can no longer rely on their own sense of what’s true. The relationship safety also erodes: honest concerns are dismissed, blamed, or twisted, creating a chilling effect where speaking up feels dangerous or pointless.

This dynamic differs from simply reassuring someone or disagreeing in a healthy way, because gaslighting aims to control by undermining reality, not by offering support or constructive dialogue. It’s also not about physical aggression; the harm here is psychological domination that destabilizes the partner’s sense of self. In short, it’s manipulating someone to doubt their reality, which undermines their confidence, autonomy, and the overall safety and functioning of the relationship.
