Abstract

The Guilford-Zimmerman Temperament Survey (GZTS) is a widely used personality inventory; however, its length (300 items) poses a significant drawback in many assessment contexts. This paper presents two studies that employed Item Response Theory (IRT) to develop a psychometrically robust short form of the GZTS (GZTS-SF), specifically designed for university students. Study 1 involved 850 students who completed the full version of the GZTS. Using the 2-Parameter Logistic (2PL) IRT model, items were selected based on optimal discrimination and difficulty parameters, ensuring comprehensive coverage across all ten GZTS traits. Items exhibiting differential item functioning (DIF) across gender were removed to enhance measurement fairness.Study 2 evaluated the resulting 100-item GZTS-SF using a separate sample of 400 university students. The short form demonstrated reliability coefficients that were comparable to or better than those reported for existing short forms, high correlations with the corresponding full-scale GZTS scores, and strong convergent and discriminant validity when assessed against the Big Five Inventory (BFI). Exploratory Structural Equation Modeling (ESEM) further supported the ten-factor structure of the GZTS-SF. Overall, the GZTS-SF offers a more efficient yet psychometrically sound method for assessing the ten GZTS traits, making it highly suitable for research and applied contexts involving university populations.

Abstract

This study investigates the cognitive emotion regulation strategies applied by ISIS Iraq attack survivors in general and specific psychological results and effects of war-related trauma. This cross-sectional study intended to investigate gender and age differences in the use of maladaptive and adaptive coping strategies, utilizing the Cognitive Emotion Regulation Questionnaire-Arabic Version (CERQ-AR) among 420 survivors from Mosul, Iraq. Data were analyzed using confirmatory factor analysis (CFA), independent t-tests, and correlational analysis. Results showed that males scored significantly higher than females on rumination, catastrophizing, and other-blame. However, no gender difference was found in the case of adaptive strategies. The finding implies that these differences could be a function of the traditional gender roles in Iraqi society, especially in conservative areas like Mosul. Secondly, age as a variable in how these strategies are adopted: older individuals show a decline in maladaptive coping but an increase in other-blame. The research study ended with the recommendation that such cognitive emotion regulation strategies in post-conflict settings should be pursued through gender- and age-specific interventions.
