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.

Abstract PDF
Background:

The purpose of this study was to examine the effects of monetary motivation on the relationship between pain-related fear and avoidance behavior.

Methods:

Eighty healthy volunteers were randomly assigned to one of four groups in accordance with task conditions of pain-related fear (high or low) and monetary motivation (high or low).

Results:

The autonomic nervous system was more active in the high pain-related fear group than in the low pain-related fear group as the participants watched a video and performed a task. Also, pain-related fear and monetary motivation had a significant interaction effect on avoidance behavior. High monetary motivation was associated with a shorter delay time during task performance in the high pain-related fear group. No significant difference was observed in the delay time in the low pain-related fear group.

Conclusions:

This study provides empirical evidence supporting the modified fear-avoidance model and experimentally proves the activation of the goal shielding mechanism.
