Investigated was the relationship between pain catastrophizing and pain intensity in adolescents suffering from chronic pain (n = 38) and the extent to which they expressed communicative pain and pain-related protective behaviours. Adolescents were observed on video performing a 2-Min Walk Test (2MWT). Behaviours were coded on videotape. The adolescents' verbalizations about the 2MWT were also rated by their parents. Analyses revealed that higher levels of catastrophic thinking about pain were associated with higher levels of facial pain expressions and verbalizations about their pain experience, beyond the effects of age, gender, pain duration and pain intensity. Pain-related protective behaviours did not vary with the adolescents' level of pain catastrophizing, but varied with pain intensity. The findings corroborate the functional distinctiveness of different types of pain behaviours. The results are discussed in terms of the processes linking (1) catastrophizing to communicative pain behaviours and (2) pain to pain-related protective behaviours.
本研究调查了慢性疼痛青少年（n = 38）的疼痛灾难化与疼痛强度之间的关系，以及他们表达交流性疼痛和疼痛相关保护行为的程度。通过视频观察青少年进行2分钟步行测试（2MWT）。行为在录像带上进行编码。青少年关于2MWT的言语表达也由他们的父母进行评分。分析表明，除了年龄、性别、疼痛持续时间和疼痛强度的影响外，对疼痛的灾难化思维水平越高，面部疼痛表情和关于疼痛经历的言语表达水平越高。疼痛相关保护行为并不随青少年的疼痛灾难化水平而变化，但随疼痛强度而变化。这些发现证实了不同类型疼痛行为的功能独特性。从将（1）灾难化与交流性疼痛行为联系起来以及（2）疼痛与疼痛相关保护行为联系起来的过程方面对结果进行了讨论。
