    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.

    Psychological Correlates of Performance-Enhancing Drug Use: Emotional, Cognitive, and Social Functioning in Long-Term and Short-Term Users
    (Frontiers Media SA, 2025) Cinaroglu, Metin; Yilmazer, Eda
    Introduction Performance-enhancing drug (PED) use-particularly anabolic-androgenic steroids (AAS)-has expanded from competitive sport into mainstream fitness settings. Although PED use is associated with emotional, cognitive, and social difficulties, less is known about how duration of use or psychosocial factors shape these outcomes. Understanding these dynamics is essential for identifying individuals at greater risk for psychological impairment.Methods A total of 285 adult gym-goers (87 long-term users, 95 short-term users, 103 non-users) completed validated measures of depression (BDI-II), anxiety (BAI), muscle dysmorphia (MDDI), self-efficacy (GSE), social support (MSPSS), and social functioning (SASS), along with the Stroop test assessing executive function. Group comparisons, multiple regressions, and PROCESS-based mediation and moderation analyses were conducted, controlling for demographic covariates.Results Long-term PED users reported significantly higher depression, anxiety, and muscle dysmorphia than short-term users and non-users, and showed poorer Stroop interference performance. Mediation analysis revealed that depression and anxiety partially explained the link between PED use and poorer social functioning. Moderation results indicated that stronger self-efficacy and higher perceived social support buffered depressive and anxious symptoms among users.Discussion Chronic PED use is associated with heightened emotional distress and reduced executive functioning, which in turn contribute to impaired social functioning. However, psychosocial resources such as self-efficacy and social support may mitigate these adverse effects. These findings underscore the need for routine psychological assessment and the development of supportive, prevention-oriented interventions for individuals engaged in PED use.

    Volumetric and Cortical Thickness Alterations in Alcohol Dependence: Evidence of Accelerated Brain Aging and Clinical Correlations
    (Frontiers Media SA, 2025) Cinaroglu, Metin; Yilmazer, Eda; Ulker, Selami Varol; Tacyildiz, Kerime; Tarlaci, Sultan
    Background: Chronic alcohol dependence is associated with structural brain changes that resemble premature aging, particularly in frontal, parietal, and subcortical regions. This study examined brain volume, cortical thickness, and brain-predicted age in individuals with alcohol dependence and assessed associations with clinical symptoms. Methods: Thirty-one alcohol-dependent patients (mean age = 37.8 +/- 7.3 years) and 26 age-matched healthy controls (mean age = 35.0 +/- 8.5 years) underwent high-resolution T1-weighted MRI scanning. Brain structural analyses, including regional volumetry and cortical thickness estimation, were conducted using the validated volBrain platform. The system also provided individualized brain-predicted age estimates via its machine learning-based Brain Structure Ages (BSA) pipeline. Clinical assessments included the Michigan Alcoholism Screening Test (MATT), Penn Alcohol Craving Scale (PENN), Beck Depression and Anxiety Inventories (BDI-II, BAI), and detailed alcohol use history. Results: Alcohol-dependent participants showed significant reductions in total white matter, right frontal lobe, inferior frontal gyrus, bilateral postcentral gyri, and left superior occipital gyrus volumes (p < 0.05), along with widespread cortical thinning. Brain-predicted age was on average 11.5 years greater in patients than in controls (p < 0.001), especially in white matter and basal ganglia structures. Higher MATT scores correlated with reduced right precentral gyrus and left caudate volumes. PENN scores were positively associated with occipital volumes; however, this association weakened after controlling for age. Depression was linked to reduced frontal pole and increased amygdala volume, while anxiety was associated with smaller orbitofrontal and angular gyrus volumes. Conclusions: Alcohol dependence is marked by diffuse brain atrophy and accelerated brain aging. Structural alterations correspond to addiction severity, craving, and mood symptoms, highlighting brain-predicted age as a potential biomarker of cumulative alcohol-related neurodegeneration.
