The religious faith item of the Spanish Posttraumatic Growth Inventory (PTGI) and its Short Form (PTGI-SF): challenges and solutions.

Background: The Posttraumatic Growth Inventory (PTGI) and its Short Form (PTGI-SF) are two instruments highly used in research on posttraumatic growth. They include a religious growth item that has been demonstrated to be problematic in cultures that are not very religious. Previous research has addressed this issue in other countries, but no attention has been paid to this critical problem in Spanish samples.Objective: Our aim is to address the psychometric issues presented by the religious growth item in Spain.Method: To do so, we reviewed several studies conducted with various populations in Spain.Results: The scores of the religious growth item in Spain present very low means and standard deviations, as well as high skewness and kurtosis, all of which point to a floor effect. The item scores show low item-test correlations, and it has failed to load on a specific dimension in factor analyses, thus casting doubts about its validity.Conclusions: The inventory does not seem to work properly in its current form in Spain. The inappropriateness of the item measuring religious growth in Spain may be due to cultural reasons. We recommend using the PTGI expanded version (PTGI-X) instead of the PTGI and exploring the possible substitution of the religious growth item in the PTGI-SF for an alternative item. In both cases, ascertaining the psychometric properties of the scores in Spain will be necessary.

The religious growth item in the PTGI and the PTGI-SF show serious psychometric validity issues in Spain. The PTGI Expanded version (PTGI-X) should be used instead of the PTGI in Spain. For the PTGI-SF, the religious item needs to be substituted.

Trauma exposure and psychometric properties of the life events checklist among adults in South Africa.

Background: Trauma exposure is widespread and linked to chronic physical and mental health conditions including posttraumatic stress disorder. However, there are major gaps in our knowledge of trauma exposure in Africa and on the validity of instruments to assess potentially life-threatening trauma exposure.Objective: The Life Events Checklist for the DSM-5 (LEC-5) is a free, widely used questionnaire to assess traumatic events that can be associated with psychopathology. As part of a case-control study on risk factors for psychosis spectrum disorders, we used the LEC-5 to examine the frequency of traumatic events and to assess the questionnaire's factor structure in South Africa (N = 6,765).Method: The prevalence of traumatic events was measured by individual items on the LEC-5 across the study sample, by case-control status, and by sex. Cumulative trauma burden was calculated by grouping items into 0, 1, 2, 3, and ≥4 traumatic event types. Psychometric properties of the LEC-5 were assessed through exploratory and confirmatory factor analyses.Results: More than 92% of the study sample reported experiencing ≥1 traumatic event; 38.7% reported experiencing ≥4 traumatic event types. The most endorsed item was physical assault (65.0%), followed by assault with a weapon (50.2%). Almost 94% of cases reported ≥1 traumatic event compared to 90.5% of controls (p < .001) and 94% of male participants reported ≥1 traumatic event compared to 89.5% of female participants (p < .001). Exploratory factor analysis revealed a 6-factor model. Confirmatory factor analyses of three models found that a 7-factor model based on the South African Stress and Health survey was the best fit (standardized root mean square residual of 0.024, root mean square error of approximation of 0.029, comparative fit index of 0.910).Conclusion: Participants reported very high exposure to traumatic events. The LEC-5 has good psychometric priorities and is adequate for capturing trauma exposure in South Africa.

Trauma exposure was extremely prevalent in this South African sample, with less than 8% of participants reporting zero exposure to traumatic events.This was the first time the factor structure of the LEC-5 was assessed in South Africa.A confirmatory factor analysis using a 7-factor model based on a previous study of trauma exposure, the South African Stress and Health study (SASH), was the best fit for the LEC-5.
