The factor structure of the posttraumatic growth inventory: A comparison of five models using confirmatory factor analysis

Journal of Traumatic Stress, 2008

There are different views about the dimensions of the positive changes resulting from the struggle with traumatic events. Using Posttraumatic Growth Inventory (PTGI) data reported by participants (N = 926) experiencing a variety of traumatic events, five models of the underlying structure of the PTGI were tested via confirmatory factor analyses to examine whether the PTGI comprises three domains (Changed Perception of Self, Changed Interpersonal Relationships, and Changed Philosophy of Life), five factors (Relating to Others, New Possibilities, Personal Strength, Spiritual Change, and Appreciation of Life), or a unitary dimension. Results indicated an oblique 5-factor model best fit the data, thus revealing the PTGI was multidimensional. Present findings offer implications for understanding the nature of posttraumatic growth.

A Systematic Review of the Factors Associated with Post-Traumatic Growth in Parents Following Admission of Their Child to the Intensive Care Unit

Journal of Clinical Psychology in Medical Settings

This systematic review aims to identify the demographic, clinical and psychological factors associated with post-traumatic growth (PTG) in parents following their child’s admission to the intensive care unit (ICU). Papers published up to September 2021 were identified following a search of electronic databases (PubMed, Medline, Web of Science, PsycINFO, CINAHL, PTSDpubs and EMBASE). Studies were included if they involved a sample of parents whose children were previously admitted to ICU and reported correlational data. 1777 papers were reviewed. Fourteen studies were eligible for inclusion; four were deemed to be of good methodological quality, two were poor, and the remaining eight studies were fair. Factors associated with PTG were identified. Mothers, and parents of older children, experienced greater PTG. Parents who perceived their child’s illness as more severe had greater PTG. Strong associations were uncovered between PTG and post-traumatic stress, psychological well-being a...

A psychometric evaluation of hierarchical and oblique versions of five variants of the Posttraumatic Growth Inventory

Psychiatry research, 2016

The Posttraumatic Growth Inventory (PTGI; Tedeschi and Calhoun, 1996) is the most commonly used measure of posttraumatic growth. Although the original five factor structure has extensive psychometric support, evidence exists for alternate PTGI models. The current study assessed the validity of oblique and hierarchical factor structures of five PTGI models. Confirmatory factor analyses were performed among a heterogeneous community sample with a diverse trauma history. The oblique models provided a better fit to the data compared with their respective hierarchical models. Three oblique variants provided good fit to the data on two fit indices and all five oblique variants met the recommended criteria for at least one fit index. The 10-item model demonstrated the lowest Expected Cross-Validation Index (ECVI) values and is a brief and useful measure when examining PTGI total scores; however, current results suggest that consideration of the specific subscales may be more meaningful tha...

Posttraumatic Growth Inventory: Factor Structure in the Context of DSM-IV Traumatic Events

ISRN Psychiatry, 2012

Studies examining the dimensionality of the Posttraumatic Growth Inventory (PTGI) have yielded varying results. To date, no study has investigated the measure's factor structure in the context of DSM-defined traumatic events. The present study examined the structure in an undergraduate student sample (N=379) reporting DSM-IV Criterion-A potentially traumatic events. Confirmatory factor analysis (CFA) did not support the original five-factor structure. Follow-up exploratory factor analysis and CFA on random halves of the sample showed poor model fit for 1-, 3-, and 7-factor models. Results suggest that the PTGI factor structure is unclear amongst individuals with DSM-IV traumatic events, and continued use of the total score is most appropriate. Future directions including the utility of the PTGI factors are discussed.

Posttraumatic growth and its measurement: A closer look at the PTGI’s psychometric properties and structure

2021

Despite its negative connotation, surviving trauma can result in improvements in some of the domains of one’s life. This phenomenon is known as posttraumatic growth and is usually measured using the Posttraumatic Growth Inventory (PTGI). Given the ambiguous results of the existing validation studies, the present study aimed to verify the psychometric properties of the Slovak version of the (PTGI) in a representative sample of Slovak citizens. Although the results suggest that a modified one-factor structure fitted the data best, other issues such as extremely high correlations between the latent factors, related to the PTGI’s factor structure were observed. It is likely that the application of the latent variable model does not represent the essence of PTG adequately and the network approach thus appears to be a far more suitable conceptualization of PTG. More detailed information on between-person differences and within-person changes in PTG could help to tailor more effective inte...
