Summary
A new 10-item short form of the Posttraumatic Growth Inventory-Expanded (PTGI-X-SF) effectively measures posttraumatic growth (PTG) across all domains. This validated, brief tool is suitable for diverse research and clinical settings.
Area of Science:
- Psychology
- Clinical Psychology
- Psychometrics
Background:
- The Posttraumatic Growth Inventory (PTGI) and its expanded version (PTGI-X) are established measures of personal growth after trauma.
- The PTGI-X includes spiritual and existential changes, but a shorter version is needed for clinical utility.
Purpose of the Study:
- To develop and validate a short form of the PTGI-X (PTGI-X-SF) that maintains its five core domains.
- To create a brief, psychometrically sound measure for assessing posttraumatic growth (PTG).
Main Methods:
- Analysis of an international sample of 2,093 adults who completed the PTGI-X.
- Confirmatory factor analysis was used to evaluate the factor structure of the proposed short form.
Main Results:
- The developed PTGI-X-SF consists of 10 items, with two items from each of the five PTGI subscales.
- Confirmatory factor analysis supported the model fit, validating the PTGI-X-SF as a brief measure of PTG.
Conclusions:
- The PTGI-X-SF is a concise and psychometrically validated instrument for assessing PTG across all domains.
- This short form is suitable for research and clinical settings, offering an efficient tool for evaluating responses to adversity.

Self-report inventories are objective personality assessments that use multiple-choice items or numbered scales, typically ranging from 1 (strongly disagree) to 5 (strongly agree). They are often called Likert scales after Rensis Likert. These inventories are widely used due to their ease of administration and cost-effectiveness. One of the most prominent examples is the Minnesota Multiphasic Personality Inventory (MMPI), initially developed in the 1940s to assess abnormal personality traits.

Interpersonal psychotherapy (IPT) is a structured, time-limited therapeutic approach initially developed to treat depression. It integrates key concepts from psychodynamic, humanistic, and cognitive-behavioral therapies, making it a uniquely eclectic framework. The therapy is rooted in the interpersonal theories of Adolph Meyer and Harry Stack Sullivan, as well as John Bowlby's attachment theory, and focuses on the interplay between interpersonal relationships and emotional well-being.

Self-esteem, a core aspect of psychological well-being, reflects an individual's positive and negative self-evaluation in terms of worth, competence, and overall value. It is both a stable trait and a dynamic process, influenced by experiences and social interactions across the lifespan. While global self-esteem offers a general assessment, research highlights that self-esteem is multidimensional and varies across specific life domains.Domain-Specific Self-EsteemResearchers have delineated...
