The role of negative self-statements during exposure in vivo. A process study of eight panic disorder patients with agoraphobia.
Stop exposure when negative thoughts hit zero—this predicts success better than heart-rate calm.
01Research in Context
What this study did
Eight adults with panic disorder and agoraphobia went through in-vivo exposure. Each person walked or drove their own feared route while saying aloud every thought they had.
Researchers counted negative self-statements minute-by-minute. They also tracked heart rate and anxiety levels to see which measure best predicted who got better.
What they found
People who ended exposure with zero negative thoughts improved the most. Heart rate and anxiety habituation did not predict outcome.
Negative self-talk dropped before heart rate settled. Waiting for heart-rate calm often ended sessions too early.
How this fits with other research
Last et al. (1984) saw no link between cognitive change and outcome. The key difference: they added separate cognitive lessons. Rojahn et al. (1994) only measured thoughts that showed up during exposure.
Emmelkamp et al. (1986) already showed exposure beats cognitive therapy alone. The new finding tells us why: the critical piece is the drop in scary thoughts inside the real task, not a later worksheet.
Gustavson et al. (1985) found therapist chatter had little impact. Together the papers say: focus on the client's moment-to-moment thoughts, not your own talk.
Why it matters
End exposure when the client reports zero negative thoughts, not when heart rate flattens. This simple rule gives you a clearer finish line and may shorten sessions. Track thoughts out loud each minute; keep the task running until the count hits zero. Use this with any adult avoidance hierarchy you already run.

03Original abstract
The purpose of this study was to evaluate the pattern of cognitive change, and in particular the role of negative self-statements, in relation to improvement during an in vivo exposure treatment. Eight panic disordered patients with agoraphobia, of whom 4 were most and 4 were least improved on a composite measure, were exposed to standardized agoraphobic situations. During the exposure, heart rate, self-statements, and subjective anxiety were registered throughout the sessions. Fixed criteria were set for habituation of heart rate and reduction of subjective anxiety within a session. Results showed that the total frequency of negative self-statements at the start, during, as well as at the end of treatment differentiated best between the most and least improved patients. These results suggest that it may be therapeutically wise to continue exposure therapy not only until habituation of anxiety (subjectively and physiologically) is achieved, but also until the frequency of negative self-statements is reduced until zero.
