The Development and Validation of an Integrated Assessment of Irrational Beliefs Concerning Basic Psychological Needs: The Rational Emotive Self-Determination Scale for Workers
(Frontiers Media Sa, 2025) Artiran, Murat; Tinaz, Pinar; Simsek, Omer Faruk; Miller, Anthony; Vione, Katia Correa; Turner, Martin James
Introduction Recently a new approach to understanding human behaviour has emerged that integrates rational emotive behaviour therapy (REBT) from the cognitive behavioural tradition, and self-determination theory (SDT) from the humanistic tradition. In the current study, we develop a psychometric that conceptualizes this new approach in organisational settings; the rational emotive self-determination scale for work (RESD-W). The RESD-W assesses respondents' irrational beliefs (from REBT) concerning the basic psychological needs (from SDT), namely perceptions of autonomy, competence, and relatedness within their work life. The RESD-W builds on initial validations of the RESD in adolescent populations (RESD-A).Methods In the current paper, the psychometric properties of the 16-item RESD-W were examined across five studies, in which the factor structure, the reliability of the scale, and construct and criterion-oriented validity of the RESD-W were assessed.Results Analyses confirmed theoretical expectations and yielded good psychometric properties. Scores in the RESD-W were associated with anxiety and depression, and negative emotions in the workplace.Discussion The results are discussed regarding practice, highlighting that work related psychological wellbeing may be predicated on the integration of irrational beliefs and basic psychological needs.
A Theoretical Model Test of Emotional and Cognitive Reactions to Sexual Trauma

Peri- and post-trauma emotional and cognitive reactions play a pivotal role in PTSD. Illuminating the complex relationship among them necessitates a sound theoretical and statistical approach that ensures valid measurement and theory testing. Taking such an approach this study examined the relationships among peri-trauma sense of control and emotional reactions, post-trauma fear, helplessness, shame and guilt responses, and PTSD in 601 women with a history of perceived sexual trauma exposure. Participants completed an online survey involving reliable and valid measures of perceived severity of sexual trauma, post-trauma fear due to a sense of ongoing threat to safety, and sense of helplessness in life, trauma-related shame, and guilt cognitions. A theoretical model was tested using Structural Equation Modeling. The measurement and structural models provided a good fit to the data. Levels of sense of control during trauma predicted peri-trauma distress levels. Peri-trauma emotions had direct effects on post-trauma fear, helplessness, and shame, but not on guilt cognitions. Fear, sense of helplessness, and shame had direct effects on PTSD and mediated the association between peri-trauma emotions and PTSD. Although guilt cognitions had direct effects on PTSD, they were not mediators. These findings suggested that peri-trauma emotions play a role in PTSD as long as they induce chronic fear for safety, a sense of helplessness in life, and shame. Trauma-focused psychological interventions designed to overcome fear and shame, reduce helplessness, and restore a sense of control over one's life would be effective in improving PTSD in survivors of sexual violence.
