Abstract. In this five-study paper, we developed and validated the Questionnaire of ethical Leadership (QueL). We examined the factor structure of QueL using Exploratory and Confirmatory Factor Analysis, along with measurement invariance techniques, using data from more than 1,200 leaders and subordinates working in Greece. Exploratory analysis indicated two latent highly-correlated factors that were labeled “Telos” and “Ethos.” Confirmatory analysis verified a bifactor solution. The bifactor QueL showed configural, metric, and scalar invariance across independent samples of leaders and subordinates. QueL was found to be a reliable measure across time and occupational groups (leaders and subordinates). We found criterion correlations in the expected direction with other ethical leadership scales, related constructs (i.e., integrity, trust, ethical climate), as well as workplace attitudes and behaviors (i.e., burnout, organizational commitment, organizational citizenship behaviors, deviant behaviors), leadership characteristics (transformational and transactional leadership, abusive supervision, personality), and socio-demographics (i.e., educational level and gender). We conclude that the new measure is a valuable tool for measuring workplace ethical leadership.

Abstract. The Greek version of the Oldenburg Burnout Inventory (OLBI), used to assess exhaustion and disengagement from work, was analyzed using item response theory analyses to investigate the dimensionality and the psychometric properties of the measure’s items. The OLBI was administered to 617 Greek employees, of whom 314 also participated in the validation study. The results indicated that four negatively keyed items from the original measure exhibited excellent psychometric properties (item/test information functions) and were used for the construction of a shorter version of the OLBI. The scr-OLBI, composed of the first letters of the word “screening,” was tested for differential item functioning between male and female employees; no bias was detected in relation to gender. Our results reveal that the scr-OLBI is a reliable and valid indicator of work-related burnout, which appears to be functionally equivalent to the original version both theoretically and empirically, yet exhibits the advantages of a short measure.

Cancer patients’ quality of life (QoL) and distress are affected by dispositional factors such as attachment anxiety or avoidance. In this review, we aimed to provide a thorough overview of the relationship between attachment dimensions and QoL and distress among early-stage breast cancer patients. Following PRISMA guidelines, we conducted a systematic search using PubMed, PsycINFO, Scopus, Cinahl, Google Scholar, and PMC Europe. We reviewed 8 eligible studies describing 1180 patients. Insecure attachment appeared to be related to poorer QoL and higher distress levels. Avoidant attachment was more frequent and was more often associated with more negative outcomes. Healthcare providers should consider investigating modifiable personality traits in the immediate post diagnosis period to identify patients more vulnerable to mental health problems, deliver personalized care, and reduce emotional burden.
