The IDRLabs Toxic Positivity Test (IDR-TPT), Validation Study in Lebanon (SBS thesis, Haigazian University)https://doi.org/10.62811/th.0257https://haigrepository.haigazian.edu.lb/handle/123456789/299Toxic Positivity is a newly emerging construct that has captured the attention of mental health professionals (Quintero & Long, 2019; Goodman, 2022). It refers to the overgeneralization of a cheerful, optimistic state across all contexts, resulting in the nullification and invalidation of unpleasant experiences (Quintero & Long, 2019). According to Hensley (2021), negating said experiences will leave them unprocessed, which will lead them to be stored in a dysfunctional manner and to become aggravated when the triggers are evoked (Hensley, 2021). Toxic Positivity may force an individual to display socially desirable “positive emotions” and mask / hide their authentic emotions. This inability to be true to oneself can increase the feeling of inauthenticity (Simpson & Stroh, 2004) and lead the person to feel shame and guilt (Goodman, 2022). Since Toxic Positivity can possibly have potent consequences on well-being, it is crucial for the scientific community to be able to examine it. Given the recent development of the construct, little empirical research exists and only one measure has been developed to assess it, namely the Toxic Positivity Test (TPT) published by the IDRLabs (IDRLabs - TPT) with limited knowledge on its validity and reliability. As such, the aim of this study was to examine the psychometric properties of the IDR-TPT by employing a survey design. In the process, the factor structure of the tool was tested using confirmatory factor analysis and convergent and validity was assessed in relation to emotional intelligence dimensions and surface acting behavior. A total of 223 adult, English speaking participants were recruited using convenient sampling. The results of the CFA revealed that the model was a good fit for the data. Moreover, partially supporting the theoretically expected relationship TPT was related to Authenticity, Perceived Emotional Distress and this supports convergent validity. However, and nonaligned with the current study’s hypotheses the relationship between TPT, Emotional Intelligence and Surface Acting this could be explained through the choice of the tool for Emotional Intelligence (SEIS) and the level of insight and intentionality for Surface Acting. Finding suggests that further research is needed to fully understand the relationships between Toxic positivity, Emotional Intelligence, and Surface Acting.
