Commitment, Relational Uncertainty, and the Investment Model

Based on Rusbult’s investment model and Knobloch and Solomon’s conceptualization of relational uncertainty, this study investigated how uncertainty in romantic relationships affected satisfaction, quality of alternatives, investments, and commitment. 343 adults in romantic relationships completed measures of relational uncertainty, satisfaction, investment size, quality of alternatives, and commitment. Results indicated that relational uncertainty was negatively related to satisfaction, investment, and commitment, and positively related to quality of alternatives. Relational uncertainty moderated the relationship between satisfaction and commitment. The satisfaction-commitment relationship was quite strong at low levels of relational uncertainty, but as relational uncertainty increased the satisfaction-commitment relationship weakened and eventually become nonsignificant.

本研究以拉斯布尔特（Rusbult）投资模型以及诺布洛克与所罗门（Knobloch and Solomon）提出的关系不确定性（relational uncertainty）概念框架为基础，探讨了浪漫关系中的不确定性对满意度、替代选择质量、关系投入及关系承诺的影响。本研究招募343名处于浪漫关系中的成年人，令其完成关系不确定性、满意度、投入规模、替代选择质量及关系承诺相关量表的填写。研究结果表明，关系不确定性与满意度、关系投入及关系承诺呈负相关，与替代选择质量呈正相关。关系不确定性对满意度与关系承诺间的关联具有调节作用：当关系不确定性处于低水平时，满意度与关系承诺间的关联较强；随着关系不确定性升高，二者间的关联逐渐减弱，最终不再具有统计学显著性。
