中文摘要：

在前期访谈并结合国内外已有研究的基础上，编制网络成瘾领域的利弊权衡问卷（Internet Addiction Decisional Balance Questionnaire，简称IDBQ）。被试为选自北京市7所高校的1166名大学生，按大约2：3的方式将被试随机分成两组（N1＝441，N2=725）分别用于探索性因素分析和验证性因素分析。结果表明IDBQ由好处分问卷和代价分问卷组成，其中好处分问卷维度包括放松心情、获取知识、方便交流和获得成就感；代价分问卷维度包括空虚苦恼、荒废学业、人际受损、浪费金钱。IDBQ具有良好的信度和效度指标，可以作为我国大学生网络使用利弊权衡的测量工具。
