The primary purpose of this study was to examine the underlying latent factor structure of the Trauma Inventory for Partners of Sex Addicts (TIPSA), a 53-item assessment designed to assess for Post-Traumatic Stress Disorder (PTSD) in the context of sexual addiction. It was theorized that the factor structure mirrored the 5 core criteria for PTSD as constituted in DSM-5. Data were gathered from 3,199 self-selected respondents (ages 21 to 55) who completed an online version of the TIPSA. Confirmatory Factor Analysis (CFA) was performed utilizing Mplus in order to confirm the hypothesized factor structure of the TIPSA. Several modifications were …

An Examination Of The Psychometric Properties Of The Trauma Inventory For Partners Of Sex Addicts (Tipsa), Steven Scott Stokes
Theses and Dissertations
This study examined the psychometric properties of the Trauma Inventory for Partners of Sex Addicts (TIPSA). Using the Nominal Response Model (NRM), I examined several aspects of item and option functioning including discrimination, empirical category ordering, and information. Category Boundary Discrimination (CBD) parameters were calculated to determine the extent to which respondents distinguished between adjacent categories. Indistinguishable categories were collapsed through recoding. Empirically disordered response categories were also collapsed through recoding. Findings revealed that recoding solved some technical functioning issues in some items, and also revealed items (and perhaps option anchors) that were probably poorly conceived initially. In addition, nuisance …
