Depression vulnerable and nonvulnerable smokers after a failure experience: examining cognitive self-regulation and motivation.

The team brought smokers into a clinic and asked them to quit for a day. After the day ended, they told every smoker the same thing: "You failed."

Some smokers had a history of depression. Others did not. The researchers then asked everyone how motivated they felt to keep trying and how bad they felt.

Smokers with depression history said they felt worse and wanted to quit less. Yet when the team looked at how much each person actually smoked next, both groups lit up the same number of cigarettes.

In other words, the bad feelings did not match real behavior. The depression-vulnerable group only looked more defeated inside their heads.

Spriggs et al. (2016) saw a similar split in college students caught with cannabis. Students who could not handle distress used more and cared less about changing, just like the smokers here.

Garey et al. (2016) found that homeless smokers who felt high stress also reported poorer health. Together these studies show that feeling bad—whether from depression, distress, or stress—can drain motivation across different drugs and settings.

Kraijer (2000) warns us not to trust self-efficacy alone. Mood can widen the gap between what clients think they can do and what they expect to achieve. The 2008 data prove this point: mood dropped even when real smoking skill stayed flat.

When a client lapses, ask how they feel before you accept their "I can’t do this" story. A depression screen or quick mood check can show you who needs extra emotional repair, not more lectures about quitting. Target the feeling first, then rebuild the plan.
