Background:

According to the fear-avoidance model, pain becomes chronic when it is related to fear and avoidance behavior. When a pain-related threat occurs, humans instinctively use avoidance behavior strategies. However, the support of significant others is likely to inhibit avoidance behavior even with the same pain-related threat stimulus. Thus, in this study, we examined the effects of pain-related threats and social support of romantic partner on avoidance behavior inhibition.

Methods:

Participants consisted of 80 pairs of healthy undergraduate couples, and were randomly assigned to one of four group conditions in a 2×2 factorial design, with threat level (high/low) and social support (presence/absence) as factors.

Results:

The results of the experiment indicated a significant interaction between threat level and social support. Specifically, in the high-threat condition, when social support was provided, task delay time was significantly shorter than when no social support was provided. On the other hand, in the low-threat condition, the time delay difference between high- and low- social support group was not significant. Moreover, social support did not affect fear reduction.

Conclusions:

These results indicate that avoidance behaviors, which are instinctive responses to pain, can be inhibited by social support. This result would enhance understanding of the factors that have not been described in the fear-avoidance model in the pain-chronicization process, and will help expand and improve the model. We also discuss possible limitations of the study and scope for further studies.
