Reliability Generalization of the School Attitude Assessment Survey‑Revised: A Meta‑Analytic Structural Equation Modeling Approach
(Sage Publications, 2025-06-09) López López, José Antonio; López Nicolás, Rubén; Sandoval Lentisco, Alejandro; Sánchez Meca, Julio; Veas Iniesta, Alejandro; Psicología Evolutiva y de la Educación; Facultad de Psicología y Logopedia
The School Attitude Assessment Survey-Revised (SAAS-R) is a popular scale for assessing attitudinal and motivational aspects of students’ academic achievement. However, evidence on key psychometric properties of the SAAS-R such as reliability remains limited. We conducted a reliability generalization study of the SAAS-R using meta-analytic structural equation modeling (MASEM). We included studies reporting an application of the SAAS-R and providing correlation coefficients between the SAAS-R subscales. We searched ERIC, PsycINFO, Academic Search Premier, Supplemental Index, and Web of Science from database inception to July 2023. Analyses were based on 18 independent matrices from 13 studies examining 8712 participants. Our main results, based on a one-stage, correlation-based MASEM approach and with omega total as the reliability measure, yielded an overall reliability estimate of 0.795 (95% CI 0.778–0.811). This suggests that the SAAS-R offers good score reliability for research and practice purposes. Applications using adapted versions obtained on average higher score reliabilities than the original ones. We discuss the implications of these results, which need to be interpreted with caution given the important reporting limitations of the primary studies included.

Reproducibility of Published Meta-Analyses on Clinical-Psychological Interventions
(SAGE Publications, 2024-02-05) López Nicolás, Rubén; Lakens, Daniel; López López, José Antonio; Rubio Aparicio, María; Sandoval Lentisco, Alejandro; López-Ibáñez, Carmen; Blázquez-Rincón, Desirée; Sánchez Meca, Julio; Psicología Básica y Metodología; Facultad de Psicología y Logopedia
Meta-analysis is one of the most useful research approaches, the relevance of which relies on its credibility. Reproducibility of scientific results could be considered as the minimal threshold of this credibility. We assessed the reproducibility of a sample of meta-analyses published between 2000 and 2020. From a random sample of 100 articles reporting results of meta-analyses of interventions in clinical psychology, 217 meta-analyses were selected. We first tried to retrieve the original data by recovering a data file, recoding the data from document files, or requesting it from original authors. Second, through a multistage workflow, we tried to reproduce the main results of each meta-analysis. The original data were retrieved for 67% (146/217) of meta-analyses. Although this rate showed an improvement over the years, in only 5% of these cases was it possible to retrieve a data file ready for reuse. Of these 146, 52 showed a discrepancy larger than 5% in the main results in the first stage. For 10 meta-analyses, this discrepancy was solved after fixing a coding error of our data-retrieval process, and for 15 of them, it was considered approximately reproduced in a qualitative assessment. In the remaining meta-analyses (18%, 27/146), different issues were identified in an in-depth review, such as reporting inconsistencies, lack of data, or transcription errors. Nevertheless, the numerical discrepancies were mostly minor and had little or no impact on the conclusions. Overall, one of the biggest threats to the reproducibility of meta-analysis is related to data availability and current data-sharing practices in meta-analysis.

A Meta-Analysis of the Reliability of Four Field-Based Trunk Extension Endurance Tests
(MDPI, 2020-04-29) de Ste Croix, Mark; Vera-García, Francisco J; Ayala Rodríguez, Francisco; Martínez Romero, María Teresa; Sainz de Baranda Andújar, Pilar; Santonja Medina, Fernando; Sánchez Meca, Julio; Actividad Física y Deporte
This meta-analysis aimed to estimate the inter- and intra-tester reliability of endurance measures obtained through trunk extension field-based tests and to explore the influence of the moderators on the reliability estimates. The reliability induction rate of trunk extension endurance measures was also calculated. A systematic search was conducted using various databases, and subsequently 28 studies were selected that reported intraclass correlation coeﬃcients for trunk extension endurance measures. Separate meta-analyses were conducted using a random-eﬀects model. When possible, analyses of potential moderator variables were carried out. The inter-tester average reliability of the endurance measure obtained from the Biering-Sorensen test was intraclass correlation coeﬃcient (ICC)= 0.94. The intra-session reliability estimates of the endurance measures recorded using the Biering-Sorensen test, the prone isometric chest raise test, and the prone double straight-leg test were ICC= 0.88, 0.90, and 0.86, respectively. The inter-session average reliability of the endurance measures from the Biering-Sorensen test, the prone isometric chest raise test, and the dynamic extensor endurance test were ICC= 0.88, 0.95, and 0.99, respectively. However, due to the limited evidence available, the reliability estimates of the measures obtained through the prone isometric chest raise, prone double straight-leg, and dynamic extensor endurance tests should be considered with a degree of caution. Position control instruments, tools, and familiarization session demonstrated a statistical association with the inter-session reliability of the Biering-Sorensen test. The reliability induction rate was 72.8%. Only the trunk extension endurance measure obtained through the Biering-Sorensen test presented suﬃcient scientific evidence in terms of reliability to justify its use for research and practical purposes.

Reliability generalization meta‑analysis: comparing different statistical methods
(Springer, 2024-01-22) López‑Ibáñez, Carmen; López Nicolás, Rubén; Blázquez‑Rincón, Desirée M.; Sánchez Meca, Julio; Psicología Básica y Metodología; Facultad de Psicología y Logopedia
Reliability generalization (RG) is a kind of meta-analysis that aims to characterize how reliability varies from one test application to the next. A wide variety of statistical methods have typically been applied in RG meta-analyses, regarding statistical model (ordinary least squares, fixed-effect, random effects, varying-coefficient models), weighting scheme (inverse variance, sample size, not weighting), and transformation method (raw, Fisher’s Z, Hakstian and Whalen’s and Bonett’s transformation) of reliability coefficients. This variety of methods compromise the comparability of RG meta-analyses results and their reproducibility. With the purpose of examining the influence of the different statistical methods applied, a methodological review was conducted on 138 published RG meta-analyses of psychological tests, amounting to a total of 4,350 internal consistency coefficients. Among all combinations of procedures that made theoretical sense, we compared thirteen strategies for calculating the average coefficient, eighteen for calculating the confidence intervals of the average coefficient and calculated the heterogeneity indices for the different transformations of the coefficients. Our findings showed that transformation methods of the reliability coefficients improved the normality adjustment of the coefficient distribution. Regarding the average reliability coefficient and the width of confidence intervals, clear differences among methods were found. The largest discrepancies were found between the different strategies for calculating confidence intervals. Our findings point towards the need for the meta-analyst to justify the statistical model assumed, as well as the transformation method of the reliability coefficients and the weighting scheme.

The association between maternal exposure to intimate partner violence and emotional and behavioral problems in Spanish children and adolescents
(Springer, 2016-09-15) López Soler, Concepción; Alcántara López, María Vicenta; Castro Sáez, Maravillas; Sánchez Meca, Julio; Fernández Fernández, María Visitación; Psicología Evolutiva y de la Educación; Facultad de Psicología y Logopedia
This correlational cross-sectional study was designed to investigate whether the intimate partner violence (IPV) suffered by mothers (physical and psychological maltreatment), the neglect suffered by children, and the maltreatment (physical and psychological) directly suffered by children are statistically associated with an increase in the probability of the child’s suffering psychopathological problems. The sample consisted of 189 Spanish children aged 6 to 17 and their mothers, recruited from Centers of Specialized Assistance for Women Victims of IPV. The results of a canonical correlation analysis showed that the most significant problems suffered by the children were both externalizing and internalizing ones. In girls, the maltreatment suffered by their mothers was directly related to a larger frequency of somatic complaints than in boys. In addition, physical maltreatment to the mother and emotional maltreatment suffered by the child exhibited a statistically significant relationship with aggressive behaviour, thought problems, rule-breaking behaviour, attention problems, and withdrawn-depressed.

Background: The Dimensional Obsessive-Compulsive Scale (DOCS) is a well-established tool for assessing obsessive-compulsive symptomatology. A reliability generalization meta-analysis was conducted to estimate the average reliability of DOCS scores and how reliability estimates vary according to the composition and variability of samples, to identify study characteristics that can explain its variability, and to estimate the reliability induction rate. Method: A literature search produced 86 studies that met the inclusion criteria. Results: For the DOCS total scores, an average alpha coefficient of .925 was found (95% CI [.920,.931]), as well as mean alphas of .881, .905, .913, and .914 for Contamination, Responsibility, Unacceptable Thoughts, and Symmetry subscales, respectively. Moderator analysis showed that internal consistency fell signifi cantly the more clinical and subclinical participants there were in the sample, and the larger the mean score in the sample for the total scores. The most important moderator variables for the subscales were the standard deviation and the mean of the scores. Conclusions: The DOCS scores exhibited excellent internal consistency reliability for both total score and subscale scores and DOCS is suitable both for research and clinical purposes.

Differential profile of PTSD in Spanish children 2 exposed to IPV and other types of maltreatment
(MDPI, 2017) Castro Sáez, Maravillas; Alcántara López, María Vicenta; Martínez Pérez, Antonia María; Fernández Fernández, María Visitación; Sánchez Meca, Julio; López Soler, Concepción; Psicología Evolutiva y de la Educación; Facultades de la UMU::Facultad de Psicología y Logopedia
This correlational cross-sectional study was designed to investigate whether the intimate partner violence (IPV) suffered by mothers (physical and psychological maltreatment), child eyewitness of psychological and physical maltreatment suffered by the mother, the neglect suffered by children, and the maltreatment (physical and psychological) directly suffered by children are statistically associated to post-traumatic stress disorder (PTSD) symptoms exhibited by the child. In addition, the prevalence of child PTSD wasestimated, as well as the concordance between the PTSD symptoms assessed by the Child PTSD Symptom Scale (CPSS) and the Diagnostic and Statistical Manual of Mental Disorders, fourth Edition, Text Revision (DSM-IV-TR) criteria for child PTSD. The sample consisted of 152 Spanish children aged 8 to 17 and their mothers, who were recruited from Centers of Specialized Assistance for Women Victims of IPV. PTSD prevalence was 20.4%. The results of a canonical correlation analysis showed that the two types of maltreatment with the largest contribution to the canonical variable were physical maltreatment directly suffered by the child, and child eyewitness of physical maltreatment suffered by the mother. The potential developmental pathway of PTSD when both children and mothers suffer severe maltreatment needs to be examined, and this will contribute to the choice of the most effective type of specialized intervention.

Transparency in Cognitive Training Meta-analyses: A Meta-review
(Springer Nature, 2024-04-19) López Nicolás, Rubén; Sandoval Lentisco, Alejandro; Tortajada Gomariz, Miriam; López López, José Antonio; Sánchez Meca, Julio; Psicología Básica y Metodología; Facultad de Psicología y Logopedia
Meta-analyses often present flexibility regarding their inclusion criteria, outcomes of interest, statistical analyses, and assessments of the primary studies. For this reason, it is necessary to transparently report all the information that could impact the results. In this meta-review, we aimed to assess the transparency of meta-analyses that examined the benefits of cognitive training, given the ongoing controversy that exists in this field. Ninety-seven meta-analytic reviews were included, which examined a wide range of populations with different clinical conditions and ages. Regarding the reporting, information about the search of the studies, screening procedure, or data collection was detailed by most reviews. However, authors usually failed to report other aspects such as the specific meta-analytic parameters, the formula used to compute the effect sizes, or the data from primary studies that were used to compute the effect sizes. Although some of these practices have improved over the years, others remained the same. Moreover, examining the eligibility criteria of the reviews revealed a great heterogeneity in aspects such as the training duration, age cut-offs, or study designs that were considered. Preregistered meta-analyses often specified poorly how they would deal with the multiplicity of data or assess publication bias in their protocols, and some contained non-disclosed deviations in their eligibility criteria or outcomes of interests. The findings shown here, although they do not question the benefits of cognitive training, illustrate important aspects that future reviews must consider.
