A Meta-Analysis of the Diagnostic Accuracy of the SCOFF

Juan Botella; Ana R. Sepulveda; Huiling Huang; Hilda Gambara

A meta-analysis was conducted to reach a pooled estimate of the diagnostic accuracy of the SCOFF. The 15 selected studies represented a total of 882 cases and 4350 controls. The main criterion for inclusion was that the primary study had provided diagnostic classification with both a diagnostic reference and with the SCOFF (with five items and a cut-off point of two). The pooled estimates were .80 (sensitivity) and .93 (specificity). The moderator variables gender and type of measure for the diagnostic reference (interview versus psychometric tests) account for part of the observed variability. For diagnostic references based on interviews the estimate of the efficacy improves significantly. For the studies that match this criterion the sensitivity is .882 and the specificity .925 (diagnostic odds ratio, 92.19). The main conclusion was that the five questions of the SCOFF constitute a very useful screening tool, in several languages; it is highly recommended for screening purposes.

Psychological Treatments to Improve Quality of Life in Cancer Contexts: A Meta-Analysis

Alejandro de la Torre-Luque; Hilda Gambara; E. López; Juan Antonio Cruzado

This study aimed to analyze the effects of psychological treatments on quality of life among cancer patients and survivors. Additionally, it was explored the moderating influence of some medical- and treatment-related features on these effects. Scientific studies published between 1970 and 2012 were analyzed. Seventy-eight studies were included in a meta-analysis. Concerns related to samples, interventions, and standard of methodological evidence were explored across the studies. A significant overall effect size of psychological interventions was revealed (g = .35). Clinical state and use of adjuvant psychological treatment for managing medical side effects moderated this result (p < .05). Furthermore, a meta-regression model was showed significant (R2 = .30) so as to explain the quality of life change associated with psychological interventions. The psychotherapeutic benefits on depressive symptomatology were included as a moderating factor. To sum up, quality of life is improved by psychological interventions, especially when patients have to cope with medical treatment or with adjustment after the disease is treated. Psychological treatments tend to promote better outcomes when depressive symptomatology is managed. These findings support that providing psychological treatments should be considered as crucial for the patients health in cancer contexts.

Tiempo vacío y tiempo lleno. Un meta-análisis sobre los cambios en la percepción del tiempo en la edad

Hilda Gambara; Juan Botella; Y René Gempp

Resumen Para estudiar si la duración subjetiva del tiempo cambia con el paso de los años se procedió a la realización de un meta-análisis. En él se analizan algunas variables moderadoras metodológicas y contextuales. Los resultados indican que, en general, la ratio entre duración subjetiva y objetiva es superior en los mayores que en los jóvenes. Sin embargo, este resultado queda matizado cuando se consideran el método que los participantes utilizan para estimar el tiempo (el método de estimación verbal produce mayores tamaños del efecto que los métodos de producción y reproducción). Pero el resultado más novedoso encontrado originariamente en este meta-análisis ha sido el efecto significativo del empleo de intervalos vacíos frente a llenos. Se encontraron tamaños del efecto y ratios del juicio de duración en direcciones contrarias, indicando que se produce una sobreestimación de las duraciones temporales en tareas vacías, pero una infraestimación en tareas llenas. Cuando los participantes estiman lo que dura un intervalo temporal en el que hay estimulación o realizan alguna tarea durante su trascurso, los más mayores infraestiman el tiempo subjetivo.

El efecto del marco en diferentes contextes

Adelson Piñón; Hilda Gambara

Resumen A pesar de la vasta investigación que ha generado el efecto del marco desde su definición en 1981 por Tversky y Kahnemann, pensamos que en ocasiones se han confundido los tipos de marcos estudiados. En este trabajo se revisa este efecto y se justifica empíricamente, con los datos de un meta-análisis previo, la distinción entre el marco de riesgo, el marco de atributo y el marco de objetivo. Los autores profundizan en cada uno de los tipos de marcos propuestos, y analizan las limitaciones conceptuales con el fin de aclarar la investigación en este campo.
