The objective of this study was to (1) assess the effects of a group intervention called Siblings Coping Together on siblings' psychosocial adjustment compared with controls; (2) explore the potential moderating effect of siblings' gender; and (3) investigate whether the intervention was more effective for siblings with more depressive symptoms at baseline.
This was a repeated measure, parallel randomized controlled trial (RCT) with two groups. Seventy-five healthy siblings (7-16 years old, 41 males) participated. Both groups had 8 weekly 2-hr sessions. Intervention sessions had psychoeducational, social, and therapeutic problem-solving goals taught through games and crafts (n = 41); controls (n = 34) had games and crafts only. Self-reported symptoms of depression (Children's Depression Inventory, CDI) and self- and proxy-reported quality of life (QOL) (Pediatric Quality of Life Inventory, PedsQL) were obtained at baseline, postintervention, and 3 months later. Multivariable analyses with a mixed effects model were performed.
No significant main group effect or group × time interactions were found for any of the scales assessed. Significant improvement over time was found for total CDI (p < .01) and proxy-reported PedsQL total (p < .001) in both groups, which may have been attributable to the passage of time.
No sufficient evidence was obtained for the efficacy of the intervention in the current study. Future research may examine conducting a larger RCT comparing sibling support group to no treatment control group.
本研究旨在：（1）评估一种名为“兄弟姐妹共同应对”的小组干预措施对兄弟姐妹心理社会适应的影响，并与对照组进行比较；（2）探讨兄弟姐妹性别差异的潜在调节作用；（3）探究该干预措施对于基线时抑郁症状更严重的兄弟姐妹是否更为有效。
这是一项具有两组的重复测量、平行随机对照试验（RCT）。共有 75 名健康兄弟姐妹（7-16 岁，41 名男性）参与。两组均接受 8 周每周 2 小时的 8 次干预。干预组通过游戏和手工艺进行心理教育、社交和治疗性问题解决目标的教学（n=41）；对照组（n=34）仅进行游戏和手工艺活动。在基线、干预后和 3 个月后，使用儿童抑郁量表（CDI）和儿童生活质量量表（PedsQL）自我报告和代理报告评估抑郁症状（儿童抑郁量表，CDI）和自我和代理报告的生活质量（儿科生活质量量表，PedsQL）。采用混合效应模型进行多变量分析。
在评估的任何量表上，均未发现主要组间效应或组间×时间交互作用。两组的总分 CDI（p<0.01）和代理报告的 PedsQL 总分（p<0.001）均随时间显著改善，这可能归因于时间的推移。
本研究未获得干预措施有效性的充分证据。未来的研究可以检验比较兄弟姐妹支持小组与无治疗对照组的更大规模 RCT。
