- Description: The experiences in close relationships revised (ECR-R) is widely used to assess romantic attachment dimensions. Investigating cultural limitations in its applicability is imperative. This study aims to examine the instrument’s: (1) factor structure in two large and normative samples of Greek (N = 1706, M age = 16.16; SD = 2.16; 49.7% male) and Cypriot (N = 1279; M age = 15.54; SD = 0.65; 44.9% male) adolescents; (2) measurement invariance between these groups, accounting for potential gender and age effects. Results supported the two-factor structure and indicated partial invariance of the constructs between Greek and Cypriot adolescents. Findings support limitations in the use of instruments adapted for Greece in Cyprus.

- Description: Objective: This study examined the bifactor models of ADHD in three groups: adolescents from the general community (n = 214), adults from the general community (n = 366), and a clinic sample (n = 245). Method: For the adolescent sample, mothers provided ratings of the ADHD symptoms, and their teachers provided ratings for Emotional Symptoms, Conduct Problems, Hyperactivity, Peer Problems, and Prosocial Behavior. For the adult sample, all adults completed self-ratings of the ADHD symptoms and measures for depression, anxiety, and stress. For the clinic-referred sample, mothers provided ratings of the ADHD symptoms, and they were diagnosed for ADHD, Conduct Disorder/Oppositional Defiant Disorder, anxiety disorders, and depression disorders. Results: The findings for all samples supported the bifactor model, and there were differences in the way the general and specific factors correlated with the external variables. Conclusion: The findings support the validity of the bifactor model. (J. of Att. Dis. 2013; XX(X) 1-XX).

- Description: The graded response model (GRM) was used to evaluate the item response theory properties of the ADHD inattention and hyperactivity/impulsivity symptoms in the Disruptive Behavior Rating Scale-Self Report (DBRS-SR). This measure was completed by 363 adolescents, between 12 and 17. years of age. The findings showed that all symptoms were generally good for discriminating their respective latent traits. For most symptoms, their threshold values suggested that they were good at representing the appropriate traits from the mean trait levels, and their information values began to increase substantially from around -1. SD from the mean. These findings indicate good psychometric properties for the DBRS-SR. The practical and clinical implications of the findings are discussed. © 2012 Elsevier Ltd.

- Description: Confirmatory factor analytic procedures were used to examine the factor structure of Carver and White's BIS/BAS Scales, and also its invariance across adults and adolescents. This measure, developed originally for adult use, has four scales: one for the Behavioural Inhibition System, and three for the Behavioural Approach System. To accomplish the aims, 631 adults and 300 adolescents completed the measure. The findings provided good support for the 4-factor structure, and for between-group invariance for the measurement (configural and metric) and structural (factor variances and covariances) models. These results mean that data obtained on the BIS/BAS Scales from early adolescents are directly comparable to scores from adults. © 2006 Elsevier.

- Description: The study used the mean and covariance structure analysis approach to test for gender invariance for the five-factor model of personality. The participants were 220 female and 218 male adolescents, between 15 and 17 years of age. All participants completed a five-factor model self-rating questionnaire, which had five items for each factor. The results supported configural invariance. All the extraversion, conscientiousness, and emotional stability items, and all but one agreeableness item showed metric and scalar invariance. For openness, three items failed to show metric and scalar invariance. Apart from openness, all the other four latent factors showed invariance for latent variances. All the mean scores for the latent factors showed invariance. Overall, therefore, there was fairly good support for gender invariance for the five-factor model. © 2006.
