ABSTRACT The current study examined the relation between two sets of survey scale measures of adult sibling relationships. The first set of three scales assesses what adult siblings feel about, think about, and how they behave toward their siblings. These three subscales of the Lifespan Sibling Relationship Scales have established validity and reliability, with those psychometric properties confirmed in the current sample of 262 adults. The second set of nine survey items assess adult sibling comfort communicating with siblings about potentially sensitive issues and were developed by the authors for a larger longitudinal study, therefore had not been previously examined psychometrically. An exploratory factor analysis revealed two factors, comfort talking with siblings about family and life issues, both factors showed acceptable reliability. Those two factors were then used in structural equation models to explore associations with the three Riggio subscales. The final model revealed acceptable fit, = 907.51, df = 467, p <.01; RMSEA =.06, C.I. =.05.-07; CFI =.93, IFI =.93, TLI =.91, and indicated that what adults feel about and how they behave toward their siblings was predictive of what they think about their siblings, which was in turn was predictive of their reported comfort communicating with their siblings about sensitive family and life topics.

衡量成年兄弟姐妹对敏感问题的沟通舒适度

摘要 本研究考察了两组成人兄弟姐妹关系调查量表之间的关系。第一组三个量表评估成年兄弟姐妹的感受、想法以及他们对兄弟姐妹的行为方式。寿命兄弟关系量表的这三个分量表已经确定了有效性和可靠性，这些心理测量特性在当前的 262 名成年人样本中得到证实。第二组九个调查项目评估成年兄弟姐妹与兄弟姐妹交流潜在敏感问题的舒适度，并由作者开发用于更大的纵向研究，因此之前没有进行心理测量学检查。探索性因素分析揭示了两个因素，与兄弟姐妹谈论家庭和生活问题的舒适度，这两个因素都显示出可接受的可靠性。然后在结构方程模型中使用这两个因素来探索与三个 Riggio 分量表的关联。最终模型显示可接受的拟合，= 907.51，df = 467，p <.01；RMSEA =.06，CI =.05.-07；CFI =.93, IFI =.93, TLI =.91，并指出成年人对兄弟姐妹的感受和行为方式可以预测他们对兄弟姐妹的看法，这反过来又可以预测他们报告的交流舒适度与他们的兄弟姐妹谈论敏感的家庭和生活话题。
