Psychometric properties of the Reward Probability Index in a Colombian sample / Propiedades psicométricas del Índice de Probabilidad de Recompensa en una muestra Colombiana

Introduction: This study analysed the psychometric properties of the Reward Probability Index (RPI) in an online Colombian sample with 1129 participants. Method: To conduct a cross-validation study, the sample was randomly divided into two subsamples. An exploratory factor analysis was conducted with the first subsample yielding a two-factor structure. Then, the fit of this two-factor model was tested on the second subsample by conducting a confirmatory factor analysis. Results: This model obtained a good fit to the data and measurement invariance across gender was observed. The RPI also showed good internal consistency according to both Cronbach's alpha and McDonald's omega, scoring .88 in both cases. The RPI demonstrated convergent construct validity given its correlations with other related measures such as the Environmental Reward Observation Scale (r = .81), and the full version of the Behavioral Activation Scale for Depression (r = .71). Conclusions: The RPI showed good psychometric properties in this Colombian sample.

Conclusiones: el RPI mostró buenas propiedades psicométricas en esta muestra colombiana.

Psychometric properties and measurement invariance of the Work-Related Acceptance and Action Questionnaire (WAAQ) in a Colombian sample

The Work-Related Acceptance and Action Questionnaire (WAAQ) is a self-report instrument that measures psychological flexibility at work. Although this scale has been validated in some languages, its psychometric properties in Colombia are unknown, making it challenging to assess work-related psychological flexibility in this country. The present study analyzed the psychometric properties and factor structure of the WAAQ in a sample of 985 Colombian workers. The internal consistency of the WAAQ measured through coefficient alpha was .88. The one-factor model with correlated error terms between items 4 and 7 showed a very good fit to the data (RMSEA= 0.033, CFI= .998, NNFI= .997, SRMR= 0.018). The WAAQ showed metric and scalar invariance across gender, age group, socioeconomic stratum, and hierarchical level. Furthermore, it correlated negatively with psychological inflexibility, psychological distress, emotional exhaustion, and cynicism and positively with professional efficacy, work engagement, and job satisfaction. In conclusion, the WAAQ seems to be a valid self-report of work-related psychological flexibility in Colombian samples (AU)

Acceptance and Commitment Therapy for improving the performance of chess players suffering from anxiety disorders

Previous research has suggested that brief protocols based on acceptance and commitment therapy (ACT) are efficacious in improving elite chess players' performance without clinical problems. These promising results warranted the examination of the effect of longer ACT interventions with chess players suffering from emotional difficulties. This study advances in this direction by presenting two case studies of elite chess players experiencing anxiety disorders. Each participant was matched to a control participant with similar characteristics. The ACT interventions were conducted in 5 sessions and with occasional follow-ups during the following year. The primary dependent variable was an objective measure of chess performance (ELO Performance). Data analysis was conducted using the JZS+AR Bayesian hypothesis testing for single-case designs and the nonparametric Tau-U statistic. Control participants did not significantly improve their chess performance during the follow-up, but chess players who received the intervention showed significant increases in their performance. Both treated participants experienced clinically significant reductions in symptomatology and improved valued living after the intervention. This study provides empirical evidence regarding the potential benefit of applying ACT to improve chess performance in players with clinical problems (AU)

Psychometric properties of the Valuing Questionnaire in a Spaniard sample and factorial equivalence with a Colombian sample.

BACKGROUND: The Valuing Questionnaire (VQ) is considered as one of the most psychometrically robust instruments to measure valued living according to the acceptance and commitment therapy model. It consists of 10 items that are responded to on a 7-point Likert-type scale and has two factors: Progression and Obstruction. The Spanish version of the VQ showed good psychometric properties in Colombian samples. However, there is no evidence of the psychometric properties of the VQ in Spaniard samples. This study aims to analyze the validity of the VQ in a large Spaniard sample and analyze the measurement invariance with a similar Colombian sample. METHOD: The VQ was administered to a Spaniard sample of 846 adult participants from general online population. Cronbach's alpha and McDonald's omega were computed to analyze the internal consistency of the VQ. The fit of the VQ's two-factor model was tested through a confirmatory factor analysis with a robust maximum likelihood (MLR) estimation method. Afterward, we analyzed the measurement invariance across countries and gender. Convergent construct validity was analyzed with a package of questionnaires that evaluated experiential avoidance (Acceptance and Action Questionnaire-II, AAQ-II), emotional symptoms (Depression Anxiety and Stress Scale-21, DASS-21), life satisfaction (Satisfaction with Life Scale, SWLS), and cognitive fusion (Cognitive Fusion Questionnaire, CFQ). RESULTS: The internal consistency across samples was adequate (alphas and omegas were .85 for VQ-Progress and .84 for VQ-Obstruction). The two-factor model obtained a good fit to the data (RMSEA = 0.073, 90% CI [0.063, 0.083], CFI = 0.98, NNFI = 0.97, and SRMR = 0.053). The VQ showed strict invariance across countries and gender and showed theoretically coherent correlations with emotional symptoms, life satisfaction, experiential avoidance, and cognitive fusion. In conclusion, the Spanish version of the VQ demonstrated good psychometric properties in a large Spaniard sample.

Psychometric properties of the spanish version of the Valuing Questionnaire in Colombian clinical and nonclinical samples.

OBJECTIVE: 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 0.83 for Progress and 0.82 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.

Psychometric Properties and Measurement Invariance of the Maslach Burnout Inventory-General Survey in Colombia.

The Maslach Burnout Inventory-General Survey (MBI-GS) is a widely used scale that measures burnout in the general professions. Debate persists regarding the factor structure of the MBI-GS, and there is scarce empirical evidence about the reliability, validity, and measurement invariance of the MBI-GS in Spanish-speaking samples. Moreover, the psychometric properties of the MBI-GS have not been analyzed in Colombia. This study aimed to analyze the internal consistency, factor structure, measurement invariance, and convergent validity of the MBI-GS in a large sample of Colombian workers. The MBI-GS was administered to a total sample of 978 workers from three private companies in Bogotá (66.9% males, 32.7% females, 0.4% other). All subscales showed adequate internal consistency (alphas ranging from 0.72 to 0.86). The three-factor model demonstrated a very good fit to the data (root mean square error of approximation - RMSEA = 0.05, comparative fit index - CFI = 0.99, non-normed fit index - NNFI = 0.98, and standardized root mean square residual - SRMR = 0.06). The measurement invariance both at a metric and scalar level was supported across gender, age group, and socioeconomic status. The MBI-GS subscales showed the expected correlations with job satisfaction, work engagement, psychological distress, and psychological inflexibility. In conclusion, the Spanish version of the MBI-GS demonstrated good psychometric properties in a Colombian sample.

Psychometric properties of the Automatic Thoughts Questionnaire-8 in two Spanish nonclinical samples.

BACKGROUND: The ATQ is a widely used instrument consisting of 30 items that assess the frequency of negative automatic thoughts. However, the extensive length of the ATQ could compromise its measurement efficiency in survey research. Consequently, an 8-item shortened version of the ATQ has been developed. This study aims to analyze the validity of the ATQ-8 in two Spanish samples. METHOD: The ATQ-8 was administered to a total sample of 1,148 participants (302 undergraduates and 846 general online population). To analyze convergent construct validity, the questionnaire package also included the Dysfunctional Attitude Scale-Revised (DAS-R), Depression Anxiety and Stress Scale-21 (DASS-21), Acceptance Action Questionnaire-II (AAQ-II), Cognitive Fusion Questionnaire (CFQ), Generalized Pliance Questionnaire (GPQ), and Satisfaction with Life Scale (SWLS). To analyze internal consistency, we computed Cronbach's alpha and McDonald's omega. A confirmatory factor analysis was conducted to test the one-factor structure of the ATQ-8. In so doing, a robust diagonally weighted least square estimation method (Robust DWLS) was adopted using polychoric correlations. Afterward, we analyzed measurement invariance across samples, gender, groupage, and education level. Lastly, we evaluated convergent construct validity by computing Pearson correlations between the ATQ-8 and the remaining instruments. RESULTS: The internal consistency across samples was adequate (alpha and omega = .89). The one-factor model demonstrated a good fit to the data (RMSEA = 0.10, 90% CI [0.089, 0.112], CFI = 0.98, NNFI = 0.97, and SRMR = 0.048). The ATQ-8 showed scalar metric invariance across samples, gender, groupage, and education level. The ATQ-8 scores were significantly associated with emotional symptoms (DASS-21), satisfaction with life (SWLS), dysfunctional schemas (DAS-R), cognitive fusion (CFQ), experiential avoidance (AAQ-II), and generalized pliance (GPQ). In conclusion, the Spanish version of the ATQ-8 demonstrated adequate psychometric properties in Spanish samples.

Development and initial validation of the Generalized Tracking Questionnaire.

The 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.

Psychometric properties and measurement invariance of the Generalized Tracking Questionnaire-children

Self-report measures of generalized patterns of rule-following are being developed in the last years including the Generalized Pliance Questionnaire (GPQ) and the Generalized Tracking Questionnaire (GTQ). Specifically, the GTQ is a 11-item self-report developed for adults that has shown excellent psychometric properties, a one-factor structure, and criterion validity in view of its positive correlations with executive functions tests. This study aims to develop the children's version of the GTQ (i.e., Generalized Tracking Questionnaire-Children, GTQ-C). In so doing, we adapted the vocabulary of some of the GTQ items and added an additional item (i.e., the GTQ-C consisted of 12 items). Afterward, the GTQ for children (i.e., GTQ-C) was administered to a sample of 730 Colombian children and adolescents from 7 to 17 years. A cross-validation study was conducted to analyze the factor structure of the questionnaire. The analysis showed that a one-factor structure showed a good fit to the data. All items of the GTQ-C showed good discrimination indexes and the whole questionnaire showed adequate internal consistency. The GTQ-C showed measurement invariance across gender and age group. In conclusion, the GTQ-C seems to be a valid and reliable measure of generalized tracking for children that might be used to analyze the developmental trajectories of tracking and its relationship with other relevant behavioral processes

A Multiple-Baseline Evaluation of Acceptance and Commitment Therapy Focused on Repetitive Negative Thinking for Comorbid Generalized Anxiety Disorder and Depression.

Repetitive negative thinking (RNT) is a core feature of generalized anxiety disorder (GAD) and depression. Recently, some studies have shown promising results with brief protocols of acceptance and commitment therapy (ACT) focused on RNT in the treatment of emotional disorders in adults. The current study analyzes the effect of an individual, 3-session, RNT-focused ACT protocol in the treatment of severe and comorbid GAD and depression. Six adults meeting criteria for both disorders and showing severe symptoms of at least one of them participated in the study. A delayed multiple-baseline design was implemented. All participants completed a 5-week baseline without showing improvement trends in emotional symptoms (Depression Anxiety and Stress Scale - 21; DASS-21) and pathological worry (Penn State Worry Questionnaire; PSWQ). The ACT protocol was then implemented, and a 3-month follow-up was conducted. Five of the six participants showed clinically significant changes in the DASS-21 and the PSWQ. The standardized mean difference effect sizes for single-case experimental design were very large for emotional symptoms (d = 3.34), pathological worry (d = 4.52), experiential avoidance (d = 3.46), cognitive fusion (d = 3.90), repetitive thinking (d = 4.52), and valued living (d = 0.92 and d = 1.98). No adverse events were observed. Brief, RNT-focused ACT protocols for treating comorbid GAD and depression deserve further empirical tests.

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.

This 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.

Psychometric Properties and Measurement Invariance Across Gender and Age-Group of the Perseverative Thinking Questionnaire-Children (PTQ-C) in Colombia.

Recent 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 RNT.

Single-case experimental design evaluation of repetitive negative thinking-focused acceptance and commitment therapy in generalized anxiety disorder with couple-related worry

Young adults suffering from generalized anxiety disorder (GAD) show high levels of worry about different domains, with couple relationships being the most frequent one. Excessive worry in this domain might lead to couple dysfunction, which is associated with lower outcomes of cognitive behavioral therapy. The current study analyzes the effect of an individual, 3-session, acceptance and commitment therapy (ACT) protocol focused on repetitive negative thinking (RNT) in the treatment of GAD with couple relationship as the main worry domain. Three young adults with GAD participated in this study. A delayed multiple-baseline design was implemented. All participants completed a 5 to 7-week baseline without showing improvement trends in couple-related worry (Experiences in Close Relationships -Anxiety; ECR-A) and general pathological worry (Penn State Worry Questionnaire; PSWQ). Afterwards, they received the ACT protocol, and a 3-month follow-up was conducted. All 3 participants showed evidence of intervention effects on the ECR-A and PSWQ. The standardized mean difference effect sizes for single-case experimental design were very large for the ECR-A (g= 5.93) and PSWQ (g= 3.19). No adverse events were found. Brief, RNT-focused ACT protocols for treating GAD with couple relationship as the main worry domain deserve further empirical tests

Validity of the Satisfaction with Life Scale in Colombia and factorial equivalence with Spanish data / Validez de la Escala de Satisfacción con la Vida en Colombia y equivalencia factorial con datos españoles

Abstract The Satisfaction with Life Scale (SWLS) is a widely used, 5-item, 7-point Likert-type scale that measures life satisfaction. The current study aims to explore the validity of the SWLS in Colombia and its factorial equivalence with Spanish samples. The SWLS was administered to a total of 1,587 Colombian participants, including a sample of undergraduates, a sample from the general population, and a clinical sample. The internal consistency across the different samples was good (overall alpha of .89). The one-factor model found in the original scale showed a very good fit in the overall Colombian sample (RMSEA = .052, 90% CI [.034, .073]; CFI = .99; NNFI = .99). SWLS scores are significantly related to measures of valued living, emotional symptoms, negative thoughts, experiential avoidance, and cognitive fusion. The clinical sample's mean score on the SWLS was significantly lower than the scores of the nonclinical samples. Three additional Spanish samples (N = 1057) were obtained to analyze the factorial equivalence of the SWLS in Colombia and Spain. Metric and scalar invariance were observed between countries and between Colombian males and females. In conclusion, the SWLS showed good psychometric properties in Colombia and factorial equivalence with Spanish samples.

Resumen La Escala de Satisfacción con la Vida (SWLS) es una escala ampliamente utilizada para medir satisfacción vital. Consta de 5 ítems que se responden en una escala tipo Likert de 7 puntos. El objetivo de este artículo es explorar la validez del SWLS en Colombia y la equivalencia factorial con muestras españolas. Se administró el SWLS a 1587 participantes colombianos, incluyendo una muestra de universitarios, una de población general y una muestra clínica. La consistencia interna a través de muestras fue buena (alfa global de .89). El modelo unifactorial encontrado en la escala original mostró muy buen ajuste en las muestras colombianas (RMSEA = .052, 90% CI [.034, .073]; CFI = .99; NNFI = .99). Las puntuaciones del SWLS estuvieron relacionadas significativamente con medidas de vida valiosa, síntomas emocionales, pensamientos negativos, evitación experiencial y fusión cognitiva. La puntuación promedio de la muestra clínica fue significativamente menor que las de las muestras no clínicas. Se obtuvieron tres muestras españolas (N = 1057) para analizar la equivalencia factorial del SWLS en Colombia y España. Se observó invarianza métrica y escalar entre países y entre género en Colombia. En conclusión, la SWLS mostró buenas propiedades psicométricas en Colombia y equivalencia factorial con muestras españolas.

Psychometric properties of the generalized pliance questionnaire-children

Empirical research on pliance, a functional class of rule-governed behavior, has been scarce in children. This study aims to develop a children version of the Generalized Pliance Questionnaire (GPQ), a self-report developed for adults that has shown excellent psychometric properties, a one-factor structure, and criterion validity. In so doing, we adapted the vocabulary of some the GPQ items and eliminated the items with content typical of adult life. Afterwards, the GPQ for children (i.e., GPQ-C) was administered to a sample of 797 Colombian children from 8 to 13 years. All items of the GPQ-C showed good discrimination indexes and the whole questionnaire showed adequate internal consistency. A cross-validation study was conducted to analyze the factor structure of the questionnaire. The analysis showed that a one-factor structure showed a good fit to the data. The GPQ-C showed measurement invariance across gender and age group. Girls obtained higher scores than boys on the GPQ-C. Also, the GPQ-C scores seemed to decrease with age. The GPQ-C strongly correlated with measures of psychological inflexibility, repetitive negative thinking, pathological worry, and emotional symptoms. In conclusion, the GPQ-C seems to be a valid and reliable measure of generalized pliance for children

General Health Questionnaire-12 validity in Colombia and factorial equivalence between clinical and nonclinical participants.

The General Health Questionnaire - 12 (GHQ-12) is a widely used screening self-report for emotional disorders among adults. However, there is little evidence concerning the validity of the GHQ-12 in Colombia and its factorial invariance between nonclinical and clinical samples. Accordingly, the current study aims to explore the GHQ-12 validity in Colombian nonclinical and clinical samples. The GHQ-12 was administered to a total of 1641 participants, including a sample of undergraduates, one of general population, and a clinical sample. The internal consistency of the GHQ-12 across samples was good (overall alpha of .90). The one-factor model showed a good fit to the data and was considered theoretically more coherent than the two-factor model with positive and negative items loading in separate factors. Metric and scalar invariance were observed across nonclinical and clinical samples. The GHQ-12 scores were strongly and positively related to emotional symptoms and experiential avoidance, and negatively related to life satisfaction. According to the receiver operating characteristic (ROC) curves, a threshold score of 11/12 was optimal to identify emotional disorders. In conclusion, the GHQ-12 is a valid screening self-report in Colombia that provides scores that can be compared across clinical and nonclinical participants.

Psychometric properties and factor structure of the Ruminative Responses Scale-Short Form in Colombia

The Ruminative Response Scale (RRS) is the most used measure of rumination in response to depressive mood. The RRS consists of 22 items that are responded on a 4-point Likert-type scale. A 10-item version of the RRS (RRS-SF) has been developed by removing the items that overlap with items of depression measures. The RRS-SF contains two subscales (Brooding and Reflection) that showed acceptable psychometric properties in the original and Spanish version. However, the psychometric properties and factor structure of the RRS-SF have not been tested in Colombia. After warranting validity content of the Spanish version of the RRS-SF, it was administered to a total of 604 participants including a nonclinical and clinical sample. The internal consistency of both subscales was acceptable and similar to the original version. The two-factor model showed a good fit to the data and measurement invariance across samples. The clinical sample’s mean scores on the RRS-SF subscales were significantly higher than scores of the nonclinical sample. Brooding and Reflection scores were significantly related to measures of pathological worry, emotional symptoms, psychological distress, experiential avoidance, and cognitive fusion. The Spanish version of the RRS-SF showed good psychometric properties in Colombia (AU)

Psychometric properties of the Cognitive Fusion Questionnaire in Colombia / Propiedades psicosométricas del Cuestionario de Fusión Cognitiva en Colombia

Abstract The Cognitive Fusion Questionnaire (CFQ) is a recently published measure of cogni tive fusion - a key construct in the model of psychopathology of acceptance and commitment therapy (ACT). This study presents the psychometric properties and factor structure data of a Spanish translation of the CFQ in Colombia. Three samples with a total of 1,763 participants were analyzed. The Spanish CFQ showed psychometric properties very similar to the ones obtained in the original version. Internal consistency across the different samples was good (Cronbach's alpha between .89 and .93). The one-factor model found in the original scale showed a good fit to the data. Measurement invariance was also found across sample and gen-der. The mean score of the clinical sample on the CFQ was significantly higher than the scores of the nonclinical samples. CFQ scores were significantly related to experiential avoidance, emotional symptoms, mindfulness, and life satisfaction. The CFQ was sensitive to the effects of a 1-session ACT intervention. This Spanish version of the CFQ shows good psychometric properties in Colombia.

Resumen El Cuestionario de Fusión Cognitiva (CFQ) es una medida de fusión cognitiva recientemente publicada; un constructo clave en el modelo de psicopatología de la terapia de aceptación y compromiso. El presente estudio muestra las propiedades psicométricas y estructura factorial de una traducción al español del CFQ en Colombia. Se analizaron tres muestras con Fusión cognitiva; Flexibilidad psicológica un total de 1763 participantes. La versión en español del CFQ mostró resultados muy similares a los obtenidos en la versión original. La consistencia interna a través de las distintas muestras fue buena (alfa de Cronbach entre .89 y .93). El modelo unifactorial encontrado en la escala original mostró un buen ajuste a los datos. Se encontró invarianza de la medida a través de muestras y sexo. La puntuación media de la muestra clínica en el CFQ fue significativamente mayor que las puntuaciones de las muestras no clínicas. Las puntuaciones en el CFQ estuvieron significativamente correlacionadas con evitación experiencial, síntomas emocionales, mindfulness y satisfacción vital. El CFQ fue sensible a los efectos de una intervención de terapia de aceptación y compromiso de una sesión. Esta versión en español del CFQ mostró buenas propiedades psicométricas en Colombia.

The Hierarchical Factor Structure of the Spanish Version of Depression Anxiety and Stress Scale -21

The Depression Anxiety and Stress Scale-21 (DASS-21) is one of the most widely used self-reports for the measurement of emotional symptoms. However, some controversy remains concerning its factor structure. Additionally, more data of the psychometric properties of the Spanish version of the DASS-21 are needed. The aim of this study was to explore the hierarchical factor structure of the DASS-21 and to further analyze its psychometric properties in Spain and Colombia. Four samples with a total of 2980 participants completed the Spanish version of the DASS-21. Two of the samples were composed of undergraduates of each country and the other two samples were recruited online. The results strongly supported a hierarchical factor structure of the DASS-21 consisting of three first-order factors (depression, anxiety, and stress) and one second-order factor (emotional symptoms). Initial evidence of measurement invariance was found for country (Spain vs. Colombia) and sample (undergraduates vs. online). The DASS-21 showed good psychometric properties in all samples. The DASS-21 seems to be a good option to measure emotional symptoms in Spain and Colombia, and its hierarchical factor structure indicates that it provides general and specific measures of emotional symptoms that are theoretically meaningful (AU)
