Science education research is, in many ways, involved with exploring relational aspects of diverse elements that affect students’ learning outcomes; at one end, the elements may be concepts to be learned, and at the other end, the relations between students in different types of learning settings and environments and, ultimately, how such elements may interact [...]

Suggestions for revised scoring of the Tower of Hanoi test

2000

Detailed time and error analyses of the Tower of Hanoi (TOH) test was performed using four repeated assessments of eight children (ages 9-12 years), who had perceptual and problem solving deficits. The time before each move was measured. In addition to the traditionally counted time scores, new, relative time scores were computed in order to separate the planning time from the general reaction speed. New error scores were defined and sum scores of serious errors (perserative moves, illegal moves, and wrong results) and mild errors (self-corrected moves, almost performed moves, and interrupted trials) were computed. The relative planning time correlated positively with the achieved score, a…

Is Small Still Beautiful for the Strengths and Difficulties Questionnaire? Novel Findings Using Exploratory Structural Equation Modeling.

2020

Article first published online: June 17, 2018 During the present decade a large body of research has employed confirmatory factor analysis (CFA) to evaluate the factor structure of the Strengths and Difficulties Questionnaire (SDQ) across multiple languages and cultures. However, because CFA can produce strongly biased estimations when the population cross-loadings differ meaningfully from zero, it may not be the most appropriate framework to model the SDQ responses. With this in mind, the current study sought to assess the factorial structure of the SDQ using the more flexible exploratory structural equation modeling approach. Using a large-scale Spanish sample composed of 67,253 youths ag…

Rolling Psychodynamic Group for Cocaine Use Disorder: A Single-Group Study Using Multilevel Models

2017

Cocaine disorder has been shown to have an important impact on the success of treatments because it is often associated with social or occupational impairment, high relapse incidences and poor trea...

Developing professional identity through group experiential learning: A Group-Analytic experiential training approach for use with postgraduate clini…

2019

This article describes a Group-Analytic, experiential and non-directive training approach taken with postgraduate clinical psychology students in training. Based on median/large group settings, it is aimed at promoting the development of psychology students’ professional identities. It uses a particular form of experiential learning beyond the rational and cognitive aspects of traditional didactic teaching in order to stimulate students’ own involvement in the integration of their thoughts, feelings and attitudes. From a Group-Analytic perspective, the group is conceived of as an organic entity. The convenor takes up a less intrusive and non-directive role in comparison to a traditional sem…

Group Analysis and the Self: The Political-Environmental-Transpersonal

1996

In this paper the authors try to put the basis for a new sense of group analysis, meant as the psychology of the field and the future, able to unblock saturated sets of meanings. Their work with groups has shown that there is a time in the group analytic process in which the individual explores the possibility of changeover. That time is also the space for the foundation of a new Self: the space for the difference, the space for the fight for giving and receiving'.

Prevalence os sending, receiving and forwarding sexts among youths: A three-level meta-analysis.

2020

Alttes ajuts: Conselleria d'Educació, Investigació, Cultura i Esport DOGV No. 7943, ACIF, 837 2017 By systematic review with a three-level, mixed-effects meta-analysis, this paper examines the prevalence of sexting experiences among youths aimed at analyzing conceptual and methodological moderators that might explain its heterogeneity. A search was conducted of five bibliographic databases and grey literature up until February 2020. The risk of bias in primary studies was assessed. A total of seventy-nine articles met the set inclusion criteria. Mean prevalences for sending, receiving and forwarding sexts were.14 (95% CI:.12,.17),.31 (95% CI:.26,.36) and.07 (95% CI:.05,.09), respectively, e…

The Symptom in the Group Situation

1996

Group analysis is a methodology that localizes the interactions arising from patients' symptoms and personality disorders. This marks the passage from a clinical-character aspect to a direct vision of the conflictual and unconscious borders between Ego and Superego. Thus the traumatic personal history of the individual is relatively freed from the constrictions of the repetition compulsion present in the symptomatic structures. The author maintains that combined therapy (a weekly group session and a weekly individual session) reduces cases of abandonment of the group caused by the deepest resistances of the id.

2019

Background The SCL-K-9 is the latest short version of the multidimensional Symptom-Checklist 90-R. Up to now, its psychometric properties have not been clarified sufficiently as the nine items have not yet been presented exclusively in a representative sample. Therefore, psychometric properties, model fit values as well as norm-values were analyzed. Methods For the sample, N = 2,507 participants aged 14 to 92, n = 1,379 women and n = 1,128 men, and a mean age of 48.79 (SD = 17.91), were selected from the general population by random-route sampling. Confirmatory factor analyses applying full information maximum likelihood (FIML) tested the model fit. The reliability estimations and effect si…

Cross-cultural measurement invariance of the General Health Questionnaire-12 in a German and a Colombian population sample

2017

While the General Health Questionnaire, 12-item version (GHQ-12) has been widely used in cross-cultural comparisons, rigorous tests of the measurement equivalence of different language versions are still lacking. Thus, our study aims at investigating configural, metric and scalar invariance across the German and the Spanish version of the GHQ-12 in two population samples. The GHQ-12 was applied in two large-scale population-based samples in Germany (N = 1,977) and Colombia (N = 1,500). To investigate measurement equivalence, confirmatory factor analyses were conducted in both samples. In the German sample mean GHQ-12 total scores were higher than in the Colombian sample. A one-factor model …
