Behavior completion versus stimulus control in compulsive gambling. Implications for behavioral assessment.

Researchers compared two quick picture-based treatments for compulsive gambling. Adults with gambling problems got either imaginal relaxation or imaginal desensitization.

The team wanted to know if a simple relaxation picture could cut gambling as well as a long, detailed fear scene. No long interviews. No full functional analysis.

Both groups gambled less after the sessions. Imaginal relaxation worked just as well as the longer desensitization scenes.

The result backed a 'behavior completion' idea: once the client pictures the whole betting act and then relaxes, the urge drops. No need to map every trigger in advance.

Greer et al. (2020) also trimmed an assessment. They showed you can skip the interview part of an IISCA and still get the same function. Both studies say 'keep the assessment short'.

Jessel et al. (2018) and Jessel et al. (2024) found that a brief IISCA leads to 90 % plus problem-behavior reduction. Their shortcut matches the shortcut here: brief setup, strong payoff.

Coffey et al. (2020) reviewed 17 IISCA papers and praised the model for speed. The 1988 gambling paper did the same trick decades earlier, but with imaginal scenes instead of functional analyses.

If you treat adults who gamble, you can test a two-minute relaxation scene before you spend hours on trigger lists. If the urge drops, you already have a working intervention. Use the time you saved to teach replacement activities or money-management skills.
