| Summary: | A proposed strategy for attenuating the return of fear is conducting exposure therapy in multiple contexts (e.g., different locations), which is believed to enhance the generalizability of safety learning. Although conducting exposure in multiple contexts can be differentiated from conducting exposure with multiple stimuli, the two strategies are often conflated. Furthermore, researchers have not yet determined whether one of these strategies, or a combination thereof, is most effective in attenuating fear renewal.
Accordingly, the present treatment-analogue study examined the unique and combined effects of multiple-context and multiple-stimulus imagery-based exposure manipulations on threat expectancy, behavioral approach/anxiety, and attentional bias for threat over Zoom. Community adults (N = 134) who met diagnostic criteria for snake phobia were randomized to exposure to a single snake in multiple environmental contexts (MC), exposure to multiple snakes in a single environmental context (MS), or exposure to multiple snakes in multiple environmental contexts (MS/MC).
Results revealed significant reductions in threat expectancy and behavioral anxiety, but not attentional bias for threat in all three groups. However, behavioral approach declined over the course of exposure in the MS/MC condition but remained stable in the MC and MS conditions. There were no significant group differences in behavioral approach/anxiety or attentional bias at a one-week follow-up. However, participants in the MC condition reported lower threat expectancy at a one-week follow-up than the other groups and this group difference was partially mediated by lower mean distress during exposure.
Implications of these findings for the inhibitory retrieval theory are discussed.
•Unique or combined multiple-context/stimulus exposure may enhance learning.•All groups experienced lower threat expectancy & anxiety on the BAT after exposure.•Behavioral approach decreased for the combined multiple-context/stimulus group.•Attentional bias did not change over the course of the exposure manipulation.•Lower mean distress helps explain differences in threat expectancy among groups. |
