El trastorn per dèficit d’atenció amb hiperactivitat (TDAH) en la infància: l’estudi IMAT

El present treball té un doble objectiu. D’una banda, es fa una revisió sobre què és i què significa el TDAH i, d’altra banda, se centra en l’estudi IMAT que aporta dades de la sospita de prevalença del TDAH en la població infantil de la illa de Mallorca. Les dades assenyalen que el trastorn pot presentar taxes de prevalença similars a les esperades (entre el 3%-5%), sense diferències rellevants per sexes, edat, tipus de centre o zona sociodemogràfica.A les conclusions s’analitzen les limitacions i les implicacions d’aquestes dades per a la nostra comunitatEl presente trabajo tiene un doble objetivo.

Feasibility of a virtual reality program to treat children with fear of darkness with nonexpert therapists

Fear of darkness is highly prevalent and stable in children and often ends up becoming a specific situational phobia. The aim of this study is to analyze the feasibility of adapting and applying it through a Virtual Reality (VR) tool by nonexpert therapists. A pre-experimental study was carried out with six participants between the ages of 8 and 12 years old using pre- and posttreatment scales for assessing the fear of darkness. Statistically significant differences with large effects were found in all posttreatment measures: EMO (Roshenthal’s r = 0.64), WCDAN (r = 0.52), and Global item of current fear of darkness (r = 0.59). Using the Reliable Change Index (RCI) as a measure of clinically significant change, four participants improved satisfactorily, one acceptably, and the other did not improve. The results support the feasibility of using an adapted VR program to treat fear of darkness without being an expert therapist. However, more detailed experimental studies need to be carried out in order to analyze its efficacy.Viabilidad de un programa de realidad virtual para tratar niños con miedo a la oscuridad con terapeutas no expertos. El miedo a la oscuridad es muy frecuente y estable en los niños y, a menudo, termina convirtiéndose en una fobia situacional específica. El objetivo de este estudio es analizar la viabilidad de adaptarlo y aplicarlo a través de una herramienta de realidad virtual (RV) por terapeutas no expertos. Se ha llevado a cabo un estudio pre-experimental con seis participantes de 8 a 12 años de edad utilizando escalas de pre y postratamiento para evaluar el miedo a la oscuridad. Se han encontrado diferencias estadísticamente significativas con tamaños del efecto grandes en todas las medidas posteriores al tratamiento: EMO (Roshenthal’s r = 0.64), WCDAN (r = 0.52), e ítem global del miedo actual a la oscuridad (r = 0.59). Al usar el Índice de Cambio Fiable (ICF) como una medida del cambio clínicamente significativo, cuatro participantes mejoraron satisfactoriamente, uno aceptablemente, y el otro no mejoró. Los resultados apoyan la viabilidad de utilizar un programa de RV adaptado para tratar el miedo a la oscuridad sin necesidad de un terapeuta experto. Sin embargo, se necesitan estudios experimentales más detallados para analizar su eficacia

A randomized controlled trial to examine the posttreatment efficacy of neurofeedback, behavior therapy, and pharmacology on ADHD measures

Objective: To examine the efficacy of neurofeedback (NF), behavior therapy (BT), and pharmacology (PH) on the improvement of ADHD-related symptoms. Method: Fifty-nine children with ADHD (M = 8.80 years, SD = 1.92 years) were randomly assigned to one of the three treatments in a pre/post assessment design. Mother- and teacher-rated ADHD scales and children were assessed using The Integrated Visual and Auditory Continuous Performance Test (IVA/CPT). Results: The three treatments were effective on the IVA/CPT, but with different trends. BT and especially NF achieved improvement on response control and attention, and PH mainly in visual attention. On the rating scales, BT improved all measures, and NF and PH had a minor but interesting influence. Conclusion: From a global perspective, behavior therapy had the most extensive results, but PH had the greatest capacity to improve overall attention. NF was able to improve both control response and inattention. Clinical implications are discussed.Plan Nacional i+d+i PSI2008–06008-C02–0

Structural Equation Modeling of Multiple-Indicator Multimethod-Multioccasion Data: A Primer

We provide a tutorial on how to analyze multiple-indicator multi-method (MM) longitudinal (multi-occasion, MO) data. Multiple-indicator MM-MO data presents specific challenges due to (1) different types of method effects, (2) longitudinal and cross-method measurement equivalence (ME) testing, (3) the question as to which process characterizes the longitudinal course of the construct under study, and (4) the issue of convergent validity versus method-specificity of different methods such as multiple informants. We present different models for multiple-indicator MM-MO data and discuss a modeling strategy that begins with basic single-method longitudinal confirmatory factor models and ends with more sophisticated MM-MO models. Our proposed strategy allows researchers to identify a well-fitting and possibly parsimonious model through a series of model comparisons. We illustrate our proposed MM-MO modeling strategy based on mother and father reports of inattention in a sample of N = 805 Spanish children

Examining Quadratic Relationships Between Traits and Methods in Two Multitrait-Multimethod Models

Multitrait-multimethod (MTMM) analysis is one of the most frequently employed methods to examine the validity of psychological measures. Confirmatory factor analysis (CFA) is a commonly used analytic tool for examining MTMM data through the specification of trait and method latent variables. Most contemporary CFA-MTMM models either do not allow estimating correlations between the trait and method factors or they are restricted to linear trait-method relationships. There is no theoretical reason why trait and method relationships should always be linear, and quadratic relationships are frequently proposed in the social sciences. In this article, we present two approaches for examining quadratic relations between traits and methods through extended latent difference and latent means CFA-MTMM models (Pohl et al., 2008; Pohl and Steyer, 2010). An application of the new approaches to a multi-rater study of the nine inattention symptoms of attention-deficit/hyperactivity disorder in children (N = 752) and the results of a Monte Carlo study to test the applicability of the models under a variety of data conditions are described
