Both behavioral inhibition system (BIS) and behavioral approach system (BAS) sensitivity have been proposed to play a role in social anxiety; however, findings concerning the relationship between BAS and social anxiety have been mixed. Moreover, recent evidence suggests that low levels of BAS may only be associated with the social interaction subdimension of social anxiety.
Measures of BIS, BAS, social interaction anxiety, and social observation anxiety were administered to three large analogue samples.
As hypothesized, BAS was inversely related to social interaction anxiety, but was unrelated to social observation anxiety across all three samples. In addition, individuals with generalized social fears were found to report both higher levels of BIS and lower levels of BAS compared to individuals with few or specific social fears.
These findings suggest that a complete motivational account of generalized social anxiety should include both BIS and BAS.
行为抑制系统（BIS）和行为趋近系统（BAS）的敏感性都被认为在社交焦虑中发挥作用；然而，关于 BAS 与社交焦虑之间关系的研究结果却存在差异。此外，最近的证据表明，低水平的 BAS 可能仅与社交焦虑的社交互动子维度相关。
对三个大型模拟样本进行了 BIS、BAS、社交互动焦虑和社交观察焦虑的测量。
正如假设的那样，BAS 与社交互动焦虑呈负相关，但在所有三个样本中与社交观察焦虑无关。此外，与仅有少数或特定社交恐惧的个体相比，患有广泛性社交恐惧的个体报告的 BIS 水平更高，BAS 水平更低。
这些发现表明，对广泛性社交焦虑的完整动机解释应同时包括 BIS 和 BAS。
