Abstract

The purpose of this study was to both provide additional evidence of the psychometric properties of the Trauma Inventory for Partners of Sex Addicts (TIPSA), and add empirical evidence for the application of betrayal trauma theory outside the context of complex and/or historical trauma. It was hypothesized that reliability coefficients for TIPSA would exceed 0.70; TIPSA and PTSD Checklist for DSM 5 (PCL-5) scores would be significantly positively correlated; TIPSA and Composite Codependency Scale (CCS) scores would not be significantly correlated; and neither Adverse Childhood Experiences (ACE) nor Benevolent Childhood Experiences (BCE) scores would be significantly correlated with, or have a significant effect on, TIPSA or PCL-5 scores. All reliability estimates were above 0.70, and correlation between TIPSA and PCL-5 produced a Pearson’s r of 0.851 (p = 5.541 E-55), which indicated a large effect size. Correlations with additional measures produced statistically significant, yet small to weak, effect sizes (CCS: r = 0.292; ACE: r = −0.173; BCE: r = 0.244). This evidence established convergent validity of TIPSA as a measure of trauma symptoms, divergent validity of TIPSA as a measure of codependency, and added empirical evidence for utilizing betrayal trauma theory in this context.

摘要

这项研究的目的是提供性伴侣伴侣创伤量表（TIPSA）的心理计量学性质的其他证据，并为复杂和/或历史性创伤背景之外的背叛性创伤理论的应用提供经验证据。假设TIPSA的可靠性系数将超过0.70；DSM 5（PCL-5）分数的TIPSA和PTSD清单将显着正相关；TIPSA和综合共依赖性量表（CCS）得分不会显着相关；而不良儿童经历（ACE）或仁慈儿童经历（BCE）分数均不会与TIPSA或PCL-5分数显着相关或具有显着影响。所有可靠性估计都在0.70以上，并且TIPSA和PCL-5之间的相关性使Pearson的r为0。851（p = 5.541 E-55），表示效果较大。与其他措施的相关性产生统计上显着但小到弱的效应大小（CCS：r = 0.292； ACE：r = -0.173； BCE：r = 0.244）。该证据确定了TIPSA作为创伤症状的度量的收敛效度，TIPSA作为共依赖性的度量的分歧效度，并为在这种情况下利用背叛创伤理论提供了经验证据。
