As relationships change and people change the kinds of support they provide, name generators that collect information about ties that provide particular kinds of support at repeated points of time may not effectively capture ties that are active but whose roles have changed. This article shows that a significant minority of network members change the kinds of support they provide. They either discontinue a support previously provided or provide a new type of support. We examine the implications of this finding for longitudinal studies of support networks based on single name generators and show that this practice can result in frequent misperceptions of network membership change.

关系变化、网络变化和单一名称生成器在社会支持纵向研究中的使用

随着关系的变化和人们改变他们提供的支持类型，收集有关在重复时间点提供特定类型支持的关系的信息的名称生成器可能无法有效地捕获活跃但角色发生变化的关系。本文表明，极少数网络成员改变了他们提供的支持类型。他们要么停止先前提供的支持，要么提供一种新型的支持。我们研究了这一发现对基于单一名称生成器的支持网络纵向研究的影响，并表明这种做法可能导致对网络成员身份变化的频繁误解。
