Maladaptive functional relations in client verbal behavior.

The paper looks at tough client talk through Skinner's verbal operants. It calls lying a broken tact, demands a short-view mand, and obsessing a runaway intraverbal.

No new data were collected. The goal is to give clinicians a clear map for spotting why some words keep hurting the client.

When you sort clinical talk into tacts, mands, echoics, and intraverbals, the same patterns show up again and again.

Seeing these patterns lets you pick targets that match how language really works, not just how it feels.

Salzinger (2003) keeps the verbal focus but swaps Skinner's box for Relational Frame Theory. The move keeps the idea that words are behavior, yet adds derived relations.

Barnes-Holmes et al. (2018) go further. They use the MDML lens to look at whole stories, not single words. The 1983 paper is the base layer; the 2018 paper stacks narrative on top.

Belisle et al. (2022) fold the same RFT ideas into ACT. They keep the 1983 spirit of watching what words do, but add psychological flexibility as the new payoff.

Next time a client says "I can't" or spins a wild story, ask which verbal operant is paying off. Then swap the payoff. Turn a lying tact into an accurate one. Shape a bossy mand into a polite request. Cut a looping intraverbal by teaching a replacement chain. The paper gives you the sorting hat; later RFT work gives you the drill-down tools. Use both and your language interventions get sharper.
