To investigate the impact of social support on both acute stress symptoms and depression in children and adolescents following a single-incident trauma as well as the potential mediating effects of negative appraisals.
A cross-sectional concurrent design was used.
Ninety-seven children (aged 7-17 years) and a parent of each were recruited through the emergency department or in-patient ward of two metropolitan hospitals. Negative appraisals, child perception of social support, parent availability to provide social support, prior trauma and psychological difficulties, depression and acute stress symptoms were measured within 4 weeks of trauma.
Negative appraisals about the trauma were highly correlated with both acute stress and depression symptoms. Social support was negatively correlated with depression symptoms, but not acute stress symptoms. There was a trend for social support to be negatively correlated with negative appraisals. There was no evidence that negative appraisals mediated the social support-symptoms relationships.
The findings lend support to recent cognitive and developmental models of the aetiology of post-traumatic stress disorder, and the possible shared cognitive vulnerability between trauma symptoms and depression. Clinically, the results indicate that, appraisals, social support, and depression symptoms should be assessed in addition to trauma symptoms following single-incident traumatic events. The findings also suggest that when depression symptoms are present following trauma exposure, it may be useful to ensure children have adequate social support. Future research should also develop trauma specific measures of social support.
调查社会支持对单一创伤后儿童和青少年急性应激症状和抑郁的影响,以及负性评价的潜在中介作用。
采用横断面同期设计。
通过两家大都市医院的急诊室或住院病房招募了 97 名儿童(年龄 7-17 岁)及其家长。创伤后 4 周内测量了负性评价、儿童对社会支持的感知、父母提供社会支持的能力、既往创伤和心理困难、抑郁和急性应激症状。
创伤后的负性评价与急性应激和抑郁症状高度相关。社会支持与抑郁症状呈负相关,但与急性应激症状无关。社会支持与负性评价呈负相关的趋势。没有证据表明负性评价在社会支持与症状的关系中起中介作用。
研究结果支持创伤后应激障碍发病的最近认知和发展模型,以及创伤症状和抑郁之间可能存在的共同认知脆弱性。临床上,研究结果表明,在单一创伤事件后,除了评估创伤症状外,还应评估评估、社会支持和抑郁症状。研究结果还表明,在创伤暴露后出现抑郁症状时,确保儿童有足够的社会支持可能会有所帮助。未来的研究还应开发创伤特异性的社会支持措施。
