Objective To develop a short, flexible, and comprehensive tool to measure psychological distress in caregivers of malignant mesothelioma (MM) patients: the Mesothelioma Psychological Distress Tool-Caregivers version (MPDT-C). Methods Based on a systematic review of the relevant literature, aspects associated with caregiver distress were derived. Expert researchers/clinicians developed a pool of items for each identified aspect. Content validity was assessed through a multiple mixed-methods approach. A multicenter study was conducted to explore the factorial structure of the 47-item MPDT-C through Bayesian factor analysis. Results The Bayesian exploratory factor analysis revealed an underlying three-factor structure. Factors were labeled Secondary Traumatic Stress, Engagement in Caring, and Meaningful Cognitive Restructuring. All scales showed sufficient reliability and corrected item-total correlations. Females scored higher than males for Engagement in Caring. Conclusions Taking care of malignant mesothelioma patients is a stressful process that influences the caregiver's physical, emotional, and social wellbeing. Our study offers preliminary evidence in support of the adequate psychometric properties of the MPDT-C, and these should now be replicated. Results suggest that the MPDT-C is a reliable tool with which to detect the psychological distress of this traumatized population.

Abstract

Objective To develop a short, flexible, and comprehensive tool to measure psychological distress in caregivers of malignant mesothelioma (MM) patients: the Mesothelioma Psychological Distress Tool-Caregivers version (MPDT-C). Methods Based on a systematic review of the relevant literature, aspects associated with caregiver distress were derived. Expert researchers/clinicians developed a pool of items for each identified aspect. Content validity was assessed through a multiple mixed-methods approach. A multicenter study was conducted to explore the factorial structure of the 47-item MPDT-C through Bayesian factor analysis. Results The Bayesian exploratory factor analysis revealed an underlying three-factor structure. Factors were labeled Secondary Traumatic Stress, Engagement in Caring, and Meaningful Cognitive Restructuring. All scales showed sufficient reliability and corrected item-total correlations. Females scored higher than males for Engagement in Caring. Conclusions Taking care of malignant mesothelioma patients is a stressful process that influences the caregiver's physical, emotional, and social wellbeing. Our study offers preliminary evidence in support of the adequate psychometric properties of the MPDT-C, and these should now be replicated. Results suggest that the MPDT-C is a reliable tool with which to detect the psychological distress of this traumatized population.
