ABSTRACT

Objectives: The effects of sex and handedness on financial capacity performance remain unexplored both in healthy older adults and in patients with amnestic mild cognitive impairment (aMCI). Methods: The aim of this study was to study the effect of the above factors (sex, handedness, and health condition), following a factorial experimental design; hence, eight groups (each with ten individuals) with similar demographic characteristics (age and education level) were formed consisting of right/left-handed, women/men and healthy/not healthy (with a diagnosis of aMCI) older adults. Mini-Mental State Examination (MMSE) was administered as a measure of general cognitive ability, and Legal Capacity for Property Law Transactions Assessment Scale (LCPLTAS) was used as an indicator of financial capacity; moreover, GDS-15 was used to assess depressive symptomatology. Self-reports of hand preference were also included. Results: Although as expected healthy men and women regardless of their handedness outperformed aMCI patients on MMSE and LCPLTAS, performance on cash transactions, bank statement management, bill payment, financial decision making, and knowledge of personal assets from LCPLTAS is significantly higher for right-handed aMCI women compared with left-handed aMCI women. Conclusions: Future research should further elucidate the reasons for this left-handed female patient with aMCI profile in larger groups of patients. This is an exploratory study, and the small sample size limits the strength of conclusions; further studies on this topic are needed.

ABSTRACT

This study aims to validate the Greek version of the 54-item Reflective Functioning Questionnaire (RFQ), a measure designed to assess an individual's capacity for understanding themselves and others based on internal mental states. This capacity, also known as Reflective Functioning (RF) or mentalizing, is believed to play a significant role in both typical and atypical development. The validation process examined the factor structure of the RFQ and its relationship with a variety of psychosocial and clinical constructs that have theoretical and empirical links to RF. Additionally, this research investigated the factor structure's invariance across gender and age groups to determine the robustness of the instrument. A unique contribution of this work lies in examining the application of the RFQ to attachment classifications through the use of cluster analysis. The sample consisted of 875 Greek adults from the general community with a mean age of 28.5 and a median age of 22. Participants completed the Greek RFQ along with a series of self-report questionnaires assessing psychosocial constructs, including attachment, epistemic trust, emotion regulation, and psychological mindedness, as well as clinical variables such as anxiety, depression, and borderline personality traits. Our findings suggest that a shorter, 31-item version of the questionnaire provides a robust three-factor structure across a non-clinical Greek adult population. The three identified subscales are (a) excessive certainty, (b) interest/curiosity, and (c) uncertainty/confusion, all demonstrating satisfactory reliability and construct validity. The uncertainty subscale was found to be associated with insecure attachment styles, epistemic mistrust and credulity, emotional suppression, and low psychological mindedness. In contrast, the certainty and curiosity subscales were linked to secure attachment, epistemic trust, emotion reappraisal, and psychological mindedness. Uncertainty was further shown to differ significantly across probable clinical and non-clinical groups, as distinguished by cut-off scores for anxiety, depression, and borderline personality disorder (BPD). However, the certainty and interest/curiosity subscales only varied between the two BPD groups. Our results provide the first evidence supporting the use of a 31-item version of the RFQ with three validated subscales to reliably assess reflective functioning in the Greek population, demonstrating stronger psychometric properties compared to other RFQ versions reported in previous studies. Findings suggest that impaired mentalizing capacity, as measured by the RFQ, is linked to insecure attachment, epistemic mistrust and credulity, poor emotion regulation, and low psychological mindedness, and potentially plays a role in adult mental health symptoms.

ABSTRACT

Attention deficit hyperactivity disorder (ADHD) results in various functioning impairments in children's lives and families. Parents of children with ADHD report high levels of parenting stress, low levels of parental self-efficacy, and use of more authoritarian and/or permissive parenting practices than parents of typically developing children. Intervention programs need to address both children's and parents' needs and multimodal intervention programs could cover this demand. The aim of this study was to examine the efficacy of "Child ViReal Support Program"-a multi-level evidence-based comprehensive program-on parenting stress, parental self-efficacy, parenting practices, and the core symptoms of children's ADHD. Families with a child diagnosed with ADHD (n = 16) were randomly allocated to two groups (PC and CP; P = parent training, C = child training), and a cross-over design was utilized. Participating parents completed, in four different times during the study, the Parenting Stress Index-Short Form, the Parenting Sense of Competence Scale, the Parenting Styles and Dimensions Questionnaire-Short Version, and the parent form of the ADHD Rating Scale-IV. Parents from both groups, after their participation in the parent training, demonstrated reduced parenting stress, enhanced parental self-efficacy, and increased the employ of democratic parenting practices. More than that, they reported decreased levels of inattention and impulsivity/hyperactivity for their children. Evidence-based multi-level intervention programs could produce positive effects on parents and children by incorporating effective methods and tools in accordance with the needs and the demands of the family context.

ABSTRACT

The existence of items not susceptible to the event of interest is of both theoretical and practical importance. Although researchers may provide, for example, biological, medical, or sociological evidence for the presence of such items (cured), statistical models performing well under the existence or not of a cured proportion, frequently offer a necessary flexibility. This work introduces a new reparameterization of a flexible family of cure models, which not only includes among its special cases, the most studied cure models (such as the mixture, bounded cumulative hazard, and negative binomial cure model) but also classical survival models (ie, without cured items). One of the main properties of the proposed family, apart from its computationally tractable closed form, is that the case of zero cured proportion is not found at the boundary of the parameter space, as it typically happens to other families. A simulation study examines the (finite) performance of the suggested methodology, focusing to the estimation through EM algorithm and model discrimination, by the aid of the likelihood ratio test and Akaike information criterion; for illustrative purposes, analysis of two real life datasets (on recidivism and cutaneous melanoma) is also carried out.

ABSTRACT

International studies focus on the successful transition into higher education, which is considered crucial for both the students and the educational institution in the context of students' learning and adjustment in higher education. The aim of the current study was to identify student profiles that include cognitive, metacognitive, and motivational aspects of learning, but also aspects of resilience, emotion dysregulation, and anxiety. The sample consists of 316 Greek undergraduate students (18.7% males and 81.3% females). The results showed four different (meta)-cognitive-emotional learner profiles: the emotionally stable and highly adaptive learner; the emotionally dysregulated and at risk learner; the emotionally dysregulated and highly adaptive learner; the emotionally stable and at risk learner. Emotionally dysregulated and at risk learner has a lower GPA than the emotional stable and highly adaptive learner, the emotionally dysregulated and highly adaptive learner and the emotionally stable and at risk learner.

ABSTRACT

The aim of this study was to investigate the sensory aroma profiles of white wines of the indigenous Greek grape varieties Assyrtiko, Malagousia, Moschofilero, and Roditis. Twenty-three panelists evaluated 17 wines of the aforementioned varieties using the frequency of attribute citation method. Three indices were calculated to assess panel performance in terms of reproducibility. Correspondence analysis and cluster analysis were employed to investigate the sensory space of the wines. Samples of the Roditis variety were characterized mainly by Banana and Vanilla odors; Assyrtiko samples had Earthy, Mushroom, and Nutty odors, as well as Lemon and Honey for some of the samples. Malagousia wines were described as having Lemon, Grapefruit, and Citrus blossom character, and they shared some descriptors with Assyrtiko wines, such as Mushroom and Earthy, and some with Moschofilero samples, i.e., floral and citrus notes. All Moschofilero wines exhibited a floral odor profile: specifically, Rose, Jasmine, or more Citrus blossom-like. Moreover, some Moschofilero samples also revealed a Grapefruit, Lemon, and/or Earthy character, while others expressed Honey notes. In conclusion, despite common characteristics found within varieties, some samples of different varieties exhibited overlapping profiles, and in some cases, samples of the same variety were quite different from each other.

ABSTRACT

In this paper, we propose a generalization of the mixture (binary) cure rate model, motivated by the existence of a zero-modified (inflation or deflation) distribution, on the initial number of causes, under a competing cause scenario. This non-linear transformation cure rate model is in the same form of models studied in the past; however, following our approach, we are able to give a realistic interpretation to a specific class of proper transformation functions, for the cure rate modeling. The estimation of the parameters is then carried out using the maximum likelihood method along with a profile approach. A simulation study examines the accuracy of the proposed estimation method and the model discrimination based on the likelihood ratio test. For illustrative purposes, analysis of two real life data-sets, one on recidivism and another on cutaneous melanoma, is also carried out.
