    Diseños de observación longitudinales: cambio intra-individual y diferencias inter-individuales observados durante la infancia
    (Murcia: Universidad de Murcia, Editum, 2015-05) Escolano-Pérez, Elena; Blanco-Villaseñor, Ángel
    El estudio del cambio en estudios de medidas repetidas o estudios longitudinales (cross-sectional y/o cross sequential) constituye un área de notable interés en el ámbito de la Psicología del Desarrollo. Las medidas (cualitativas/cuantitativas) que tomamos de participantes, bien intraindividualmente bien interindividualmente, permiten capturar cambios del desarrollo cognitivo. Mediante un estudio empírico de desarrollo cognitivo infantil, comprobaremos si los diseños longitudinales (cross-sectional/cross-sequential) pueden utilizarse o no indistintamente con técnicas de análisis de datos uni- o multivariables. Metodológicamente es posible tratar datos longitudinales en alguna de las soluciones aportadas, uni o multivariable. Sin embargo, y aún cumpliendo los requisitos estadísticos necesarios, los resultados y la interpretación de los mismos pueden ser diferentes. Entendemos que hay soluciones en los programas estadísticos actuales que permiten la utilización de técnicas que aseguren si realmente hay diferencias significativas o no en los datos, independientemente de si son tratados con estructuras uni- o multivariables. Los resultados de bebés estudiados en tres momentos temporales (18, 21 y 24 meses) mediante medidas repetidas muestran que la interpretación afecta de igual manera a datos de la variabilidad intra/interindividual.

    Objective: During the pandemic, there has been a slight increase in obsessive- compulsive symptoms in both clinical and non-clinical samples. Three years after the pandemic, we conducted the first systematic review of prospective cohort studies assessing temporal changes in obsessive-compulsive symptoms and their extent in both patients with obsessive-compulsive disorder (OCD) and community samples, regardless of age or socio-cultural background, during any phase of the pandemic. Method: Prospective cohort studies were included if validated self-report questionnaires or standardized interviews for obsessive-compulsive symptoms were used. Studies that enrolled OCD patients were included if OCD was diagnosed before the outbreak of the pandemic. The following were our exclusion criteria: cross- sectional and case-control studies, single case studies, editorials, commentaries, and reviews. Studies assessing the effectiveness of an intervention were excluded. Results: 15 studies were included. Overall, studies showed a small upsurge in obsessive-compulsive symptoms, especially washing/contamination symptoms, during the coronavirus outbreak. The severity of symptoms seemed to follow the pattern of restriction measures and the increase in the number of COVID-19 cases. Conclusions: Factors contributing to the worsening of obsessive-compulsive symptoms during the pandemic were discussed.

    Severity and changes in OCD dimensions during COVID-19: a two-year longitudinal study
    (MDPI, 2023-07-31) Rosa Alcázar, Ángel; Parada Navas, José Luis; García Hernández, María Dolores; Pozza, Andrea; Tondi, Paolo; Rosa Alcázar, Ana Isabel; Personalidad, Evaluación y Tratamiento Psicológicos
    Background: The COVID-19 pandemic appears to be associated with a worsening of obsessive-compulsive symptoms in both young people and adults with OCD and it is necessary to analyze the variables involved in this worsening over time. The main aim of this study was to examine long-term changes in total severity and obsessive-compulsive dimensions in obsessive–compulsive patients during the COVID-19 pandemic. Method: A total 250 OCD patients were selected from various associations, clinical centers and hospitals. We discarded 75 as they did not meet the inclusion criteria. A total of 175 obsessive-compulsive participants aged between 16 and 58 years old (M = 33.33, SD = 9.42) were evaluated in obsessive–compulsive symptom severity and dimensions OCD assessed using the Y-BOCS and D-YBOCS scales in T1 (April–June 2020) and in T2 (March–April 2022). The evaluation was carried out through an online survey and face-to-face with a professional clinician at both time points. Results: Intragroup differences in severity were observed, reaching higher scores for patients with contamination, somatic, aggressive and religious. Some patients changed their main dimension, increasing the percentage of patients with contamination and somatic obsessions. Conclusions: COVID-19 was associated with both changes in severity and also affected some dimensions more than others, particularly those related to the virus itself (contamination and somatic).
