Ambivalence¶
Definition¶
Ambivalence is the simultaneous, contradictory holding of reasons both for and against a change — wanting to quit drinking and wanting to keep drinking, wanting to exercise and wanting to rest, at the same time and about the same behavior. Rosengren treats it as normal rather than pathological: "if changes were so obviously needed and so easily accomplished, they would've happened already" (paraphrased from Chapter 2). MI's own definition names ambivalence as the thing to be explored and resolved, not diagnosed and cured.
In the Book¶
Chapter 2 introduces ambivalence as a foundational premise of MI: readiness to change is not static, and clients are "failed self-changers" (citing DiClemente) who have already tried and struggled, which is why mixed feelings persist. The book returns to it directly in Chapter 8, working through the case of Carrie, a child-services supervisor who stalls a required meeting — evasive about scheduling, but, the coach knows from prior conversation, deeply committed to the welfare of the families she serves. Rather than reading her scheduling resistance as opposition, the coach treats it as ambivalence and works within it, which produces a workable 45-minute meeting instead of a standoff.
Chapter 8 also corrects a common misreading: MI does not resolve ambivalence via a "decisional balance" exercise that weighs pros and cons of both sides equally. Miller and Rollnick moved away from that technique because eliciting sustain talk (arguments for the status quo) alongside change talk turns out to work against change — DiClemente estimates that roughly two-thirds of people considering a change feel strongly ambivalent about it, and how a practitioner handles that ambivalence measurably shifts outcomes.
Why It Matters¶
Treating ambivalence as normal rather than as denial, resistance, or a character flaw changes what an intervention looks like: instead of trying to argue a person out of their doubts, you work with the fact that both sides of the argument are already present in them. This reframe generalizes past therapy — anywhere someone is stuck between two things they genuinely want (a team that wants stability and wants disruption, a customer who wants to switch vendors and wants to avoid the switching cost), naming the ambivalence as the actual terrain, rather than treating one side as the "real" position and the other as an obstacle, opens a different set of moves.
