BACKGROUND
This study used the social support effectiveness framework to examine whether effective social support buffered the relationship between stressful life events and distress among hematopoietic stem cell transplant (HSCT) survivors and whether that buffering effect depended on the type of caregiver who provided it (partner versus non-partner caregivers).
METHODS
A total of 275 HSCT survivors completed measures of the effectiveness of their caregiver's support-social support effectiveness (SSE)-distress, and stressful life events. Hierarchical linear regression was used to analyze a three-way interaction between stressful life events, caregiver SSE, and caregiver type on distress.
RESULTS
After controlling for covariates, the three-way interaction of stressful life events, caregiver SSE, and caregiver type was significant (b = - 0.21, SE = 0.00, p < 0.001). Among partnered survivors, more stressful life events were associated with greater distress (B = 0.03, SE = 0.01, p = 0.045) when caregiver SSE was low. There was no association between stressful life events and distress when caregiver SSE was average (B = 0.01, SE = 0.01, p = 0.50) or high (B = - 0.01, SE = 0.02, p = 0.61). Among non-partnered survivors, there was a positive association between stressful life events and distress regardless of caregiver SSE.
CONCLUSIONS
Average or highly effective caregiver support buffered effects of stressful life events on distress among partnered survivors. There was no evidence that support at any level of effectiveness buffered stressful life events among non-partnered survivors. Findings highlight the importance of measuring social support effectiveness and source of support among HSCT survivors.
背景
本研究使用社会支持有效性框架，检验有效社会支持是否缓冲了造血干细胞移植（HSCT）幸存者生活压力事件与痛苦之间的关系，以及这种缓冲效应是否取决于提供支持的照顾者类型（伴侣与非伴侣照顾者）。
方法
共有 275 名 HSCT 幸存者完成了照顾者支持有效性-社会支持有效性（SSE）-痛苦和生活压力事件的测量。采用分层线性回归分析生活压力事件、照顾者 SSE 和照顾者类型对痛苦的三向交互作用。
结果
在控制了协变量后，生活压力事件、照顾者 SSE 和照顾者类型的三向交互作用具有统计学意义（b=-0.21，SE=0.00，p<0.001）。在伴侣幸存者中，当照顾者 SSE 较低时，更多的生活压力事件与更大的痛苦相关（B=0.03，SE=0.01，p=0.045）。当照顾者 SSE 处于平均或高水平时，生活压力事件与痛苦之间没有关联（B=0.01，SE=0.01，p=0.50 或 B=-0.01，SE=0.02，p=0.61）。在非伴侣幸存者中，无论照顾者 SSE 如何，生活压力事件与痛苦均呈正相关。
结论
平均或高度有效的照顾者支持缓冲了生活压力事件对伴侣幸存者痛苦的影响。没有证据表明在任何水平的支持都能缓冲非伴侣幸存者生活压力事件的影响。研究结果强调了在 HSCT 幸存者中测量社会支持有效性和支持来源的重要性。
