Background: Psychological resilience is a distinct factor that affects mental health outcomes after adversities. This study describes the development, validity and measurement invariance (MI) of a Dutch and English scale on psychological resilience, called the Resilience Evaluation Scale (RES).Methods: Separate online surveys with the Dutch and English version of the RES and hypothesized related measures were distributed in a Dutch- and English-speaking group, both drawn from the general population.Results: Exploratory factor analysis, using data from 522 respondents (n = 296 Dutch, n = 226 English), yielded a two-factor structure for the final 9-item RES. The factors reflected the hypothesized underlying constructs of psychological resilience: self-confidence and self-efficacy. The items and constructs of psychological resilience as measured by the RES were interpreted and conceptualized in the same way by both language groups, with the exception of one item. The RES showed good convergent validity and good internal consistency.Conclusions: The current study establishes sound psychometric properties of a new, brief, and freely available scale on psychological resilience. This study contributes to the identification and measurement of psychological resilience after adversities. The final 9-item RES may serve as a valuable instrument in research and in clinical practice.

Olff (2020) Help in hand after traumatic events: a randomized controlled trial in health care professionals on the efficacy, usability, and user satisfaction of a self-help app to reduce trauma-related symptoms,

Little is known about how age and gender are associated with posttraumatic stress disorder (PTSD) symptoms and traumatic experiences in treatment-seeking police offers. In this study, we examined 967 diagnostic files of police officers seeking treatment for PTSD. Six hundred twelve (63%) of the referred police officers were diagnosed with PTSD (n = 560) or partial PTSD (n = 52). Police officers reported on average 19.5 different types of traumatic events (range 1-43). Those who experienced a greater variety of traumatic events suffered from more PTSD symptoms. Also, women reported more often direct life-threatening or private events as their index trauma than men and suffered from more PTSD symptoms than their male colleagues. Results indicate that police officers experience a considerable number of different traumatic events, which is significantly associated with PTSD symptoms. The results highlight the importance of early detection of PTSD symptoms in the police force.
