Abstract

Background: The reward deficiency syndrome (RDS) integrates psychological, neurological, and genetic factors of addictive, impulsive, and compulsive behaviors. However, to date, no instrument has been validated to assess the RDS construct.

Aims: The present study developed and tested a tool to assess RDS.

Methods: Data were collected on two college and university samples. Exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) were performed on Sample 1 (N = 1726), and confirmatory analysis was conducted on an independent sample (N = 253). Impulsivity and sensation-seeking were assessed.

Results: Based on EFAs, a 29-item Reward Deficiency Syndrome Questionnaire (RDSQ-29) was developed, containing four subscales (lack of sexual satisfaction, activity, social concerns, and risk-seeking behavior). CFA indicated good fit (comparative fit index (CFI) = 0.941; Tucker-Lewis index (TLI) = 0.933; root mean square error of approximation (RMSEA) = 0.068). Construct validity analysis showed strong relationship between sensation-seeking and the RDS scale.

Conclusion: The RDSQ-29 is an adequate scale assessing psychological and behavioral aspects of RDS. The RDSQ-29 assesses psychological and behavioral characteristics that may contribute to addictions generally.

奖励缺乏综合症问卷(RDSQ-29)的编制与验证。

背景:奖励缺乏综合征(RDS)综合了成瘾、冲动和强迫行为的心理、神经和遗传因素。然而，到目前为止，还没有一种工具被验证来评估RDS结构。目的:本研究开发并测试了一种评估RDS的工具。方法:收集两所高校的调查数据。对样本1 (N = 1726)进行探索性因子分析(EFA)和验证性因子分析(CFA)，对独立样本(N = 253)进行验证性分析。对冲动性和寻求刺激进行了评估。结果:在EFAs的基础上，编制了一份包含29个条目的奖励缺乏综合征问卷(RDSQ-29)，包含4个分量表(性满意度缺乏、主动性、社会关注和风险寻求行为)。CFA表示拟合良好(比较拟合指数(CFI) = 0.941;Tucker-Lewis指数(TLI) = 0.933;均方根近似误差(RMSEA) = 0.068)。构念效度分析显示，感觉寻求与RDS量表有较强的相关性。结论:RDSQ-29量表能较好地评价RDS的心理和行为方面。RDSQ-29评估可能导致成瘾的心理和行为特征。
