Publicación Psychometric properties of the spanish version of the Valuing Questionnaire in Colombian clinical and nonclinical samples(Wiley, 2022) Ruiz Vegas, Francisco Javier; Segura Vargas, Miguel Ángel; Gil Luciano, Bárbara; Suárez Falcón, Juan CarlosObjective: To examine the psychometric properties of the Spanish version of the Valuing Questionnaire (VQ) in Colombian clinical and nonclinical samples. Method: The VQ was administered to a total sample of 1820 participants, which included undergraduates (N = 762), general population (N = 724), and a clinical sample (N = 334). The questionnaire packages included measures of experiential avoidance, cognitive fusion, mindfulness, life satisfaction, and psychological difficulties. Results: Across the different samples, internal consistency was good (global Cronbach’s alpha of .83 for Progress and .82 for Obstruction). Measurement invariance was found across samples and gender, and the two-factor model obtained a good fit to the data. The latent means of Progress and Obstruction of the clinical sample were lower and higher, respectively, than the latent means of the nonclinical samples. Correlations with other variables were in the expected direction. Conclusion: The Spanish version of the VQ showed good psychometric properties.Publicación Psychometric properties and measurement invariance across gender and age-group of the Perseverative Thinking Questionnaire–Children (PTQ-C) in Colombia(SAGE Publications, 2020) Ruiz Vegas, Francisco Javier; Peña Vargas, Andrés; Salazar, D. M.; Ehring, T.; Barreto Zambrano, M. L.; Gómez Barreto, Maria P.; Suárez Falcón, Juan CarlosRecent research has found that repetitive negative thinking (RNT) is an important transdiagnostic process both in adult and child psychopathology. This finding has led some authors to design content-independent measures of RNT that can be administered across disorders. One of these instruments is the Perseverative Thinking Questionnaire (PTQ) and its version for children (PTQ-C). This study presents the Spanish translation of the PTQ-C and its psychometric analysis in a sample of 1,127 Colombian children and adolescents (8-18 years old). All items obtained good discrimination indexes, and internal consistency was excellent (.93). A cross-validation study was conducted to analyze the factor structure of the PTQ-C, which strongly supported the one-factor structure. Measurement invariances across gender and age-group (8-12 and 13-18 years old) were also found. The PTQ-C scores for older boys were lower than for younger boys, whereas the inverse pattern was found for girls. The PTQ-C showed strong correlations with measures of pathological worry, emotional symptoms, and psychological inflexibility. In conclusion, the Spanish translation of the PTQ-C appears to be a valid and reliable measure of RNTPublicación Acceptance and commitment therapy in parents of children with cancer at psychosocial risk: A randomized multiple baseline evaluation(Elsevier, 2023) Bautista, Ana B.; Ruiz Vegas, Francisco Javier; Suárez Falcón, Juan CarlosDeveloping and testing psychological interventions for primary caregivers of children with cancer at significant psychosocial risk is still needed. One psychological factor contributing to their emotional distress is repetitive negative thinking (RNT). This study conducted a randomized, multiple-baseline evaluation of the effect of an individual, online, 2-session, RNT-focused ACT intervention in 12 parents. Participants responded to daily measures of emotional symptoms, RNT, and progress in values during baseline, intervention, and the 2-month follow-up. These measures have shown adequate psychometric properties at the individual level in this study. All 12 participants completed the intervention. A Bayesian hierarchical model indicated that most participants showed reductions in emotional symptoms and RNT (10 of 11), and 8 of 12 participants showed increases in valued living. The design-comparable standardized mean difference was computed to estimate the intervention effect overall. The effect sizes were large for all variables (PHQ-4: d = 0.83, 95% CI [0.27, 1.40]; RNTQ-3: d = 0.81, 95% CI [0.34, 1.28]; VQ-3: d = 1.07, 95% CI [0.22, 1.91]). Participants evaluated the intervention as useful at the 2-month follow-up. In conclusion, a brief and online RNT-focused intervention showed promising results in parents of children with cancer at significant psychosocial risk.Publicación Efficacy of a two-session repetitive negative thinking-focused acceptance and commitment therapy (ACT) protocol for depression and generalized anxiety disorder: A randomized waitlist control trial(American Psychological Association, 2020) Ruiz Vegas, Francisco Javier; Peña Vargas, Andrés; Ramírez Riveros, Eduar S.; García Martín, María B.; García Beltrán, Diana Milena; Henao, Ángela M.; Monroy Cifuentes, Andrea; Sánchez, Pili D.; Suárez Falcón, Juan CarlosThis parallel randomized controlled trial aimed to evaluate the effect of acceptance and commitment therapy (ACT) focused on disrupting repetitive negative thinking (RNT) versus a waitlist control (WLC) in the treatment of depression and generalized anxiety disorder (GAD). Forty-eight participants with a main diagnosis of depression and/or GAD were allocated by means of simple randomization to a 2-session RNT-focused ACT intervention or to the WLC. The primary outcomes were emotional symptoms as measured by the Depression, Anxiety, and Stress Scales–21. Process outcomes included ACT- and RNT-related measures: general RNT, experiential avoidance, cognitive fusion, values, and generalized pliance. At the 1-month follow-up, linear mixed effects models showed that the intervention was efficacious in reducing emotional symptoms (d = 2.42, 95% confidence interval [1.64, 3.19]), with 94.12% of participants in the RNT-focused ACT condition showing clinically significant change in the Depression, Anxiety, and Stress Scales–21 total scores versus 9.09% in the WLC condition (70% vs. 8% in intention-to-treat analysis). The intervention effects were maintained at the 3-month follow-up. No adverse events were found. A very brief RNT-focused ACT intervention was highly effective in the treatment of depression and GAD.

A., Peña-Vargas, A., Henao, A. M., Ávila-Campos, J. E. (2020). Development and initial validation of the Generalized Tracking Questionnaire. PLOS ONE, 15(6), e0234393. doi: https://doi.org/10.1371/journal.pone.0234393(Public Library of Science, 2020) Ruiz Vegas, Francisco Javier; García Martín, María B.; Bedoya Valderrama, L.; Segura Vargas, Miguel Ángel; Peña Vargas, Andrés; Henao, Ángela M.; Ávila Campos, J. E.; Suárez Falcón, Juan CarlosThe concept of rule-governed behavior (RGB) has been used in the behavior-analytic literature as a way to analyze complex human behavior, including thinking and problem-solving. Relational frame theory suggests the existence of two main functional types of RGB termed pliance and tracking. In this paper, we describe the development of the Generalized Tracking Questionnaire (GTQ) and the preliminary evaluation of its psychometric properties and validity through three studies, with a total of 1155 participants. In Study 1, a pool of items describing the main characteristics of generalized tracking was designed and evaluated by experts on the RFT account of RGB. The resulting 11 items were administered to 460 undergraduates to examine the understandability and psychometric quality of the items. The exploratory factor analysis indicated that the GTQ can be seen as a unidimensional scale, with all items exhibiting high factor loadings and corrected item-total correlations. In Study 2, the GTQ was administered online to a sample of 464 non-clinical participants and a clinical sample of 125 participants. The one-factor model of the GTQ obtained a good fit in the conducted confirmatory factor analysis. The GTQ showed measurement invariance across gender and clinical and nonclinical participants. It also obtained excellent internal consistency and correlated in theoretically coherent ways with other constructs. In Study 3, the GTQ and a neuropsychological battery of executive functions were administered to 105 participants. The GTQ showed statistically significant, medium-size correlations with working memory tests, verbal fluency, planning, and behavioral inhibition. In conclusion, the GTQ seems to be a promising measure to advance in the empirical analysis of functional classes of RGB.
