Psychometric evaluation of the Swedish Multidimensional Psychological Flexibility Inventory (MPFI).

Psychiatric disorders are common, and reliable measures are crucial for research and clinical practice. A cross-diagnostic construct that can be used to index treatment outcomes as well as prevalence of psychological ill health is psychological flexibility. The aim of this study was to validate a Swedish version of the Multidimensional Psychological Flexibility Inventory (MPFI). The MPFI has 12 subscales, six of which measure flexibility, and six that measure inflexibility. Using confirmatory factor analysis in a community sample of 670 participants, we found that a model with two higher order factors had satisfactory fit (CFI = .933) and a 12-factor model had the best fit to the data (CFI = .955). All 12 subscales showed adequate reliability (CRs = .803-.933) and the factor structure was similar across age groups and gender. Findings suggest that the Swedish version of the MPFI is a reliable instrument that can be used to index psychological flexibility. Potential areas for improvement of the instrument are discussed.

An integer programming model to assign patients based on mental health impact for tele-psychotherapy intervention during the Covid-19 emergency.

The Covid-19 pandemic challenges healthcare systems worldwide while severely impacting mental health. As a result, the rising demand for psychological assistance during crisis times requires early and effective intervention. This contributes to the well-being of the public and front-line workers and prevents mental health disorders. Many countries are offering diverse and accessible services of tele-psychological intervention; Ecuador is not the exception. The present study combines statistical analyses and discrete optimization techniques to solve the problem of assigning patients to therapists for crisis intervention with a single tele-psychotherapy session. The statistical analyses showed that professionals and healthcare workers in contact with Covid-19 patients or with a confirmed diagnosis had a significant relationship with suicide risk, sadness, experiential avoidance, and perception of severity. Moreover, some Covid-19-related variables were found to be predictors of sadness and suicide risk as unveiled via path analysis. This allowed categorizing patients according to their screening and grouping therapists according to their qualifications. With this stratification, a multi-periodic optimization model and a heuristic are proposed to find an adequate assignment of patients to therapists over time. The integer programming model was validated with real-world data, and its results were applied in a volunteer program in Ecuador.

[Measurement of pain-related experiential avoidance: analysis of the Acceptance and Action Questionnaire-II-Pain in patients with chronic pain]. / Messung von schmerzbezogener Erlebensvermeidung: Analyse des Acceptance and Action Questionnaire-II-Pain bei Patienten mit chronischem Schmerz.

INTRODUCTION AND OBJECTIVE: Experiential avoidance is a core process variable in the concept of Acceptance and Commitment Theory (ACT) and has been connected to various disorders. A widely used instrument for the measurement of experiential avoidance is the Acceptance and Action Questionnaire II (AAQ-II). Recently, a pain-specific version for chronic pain patients was introduced in the Netherlands (AAQ-II­P). High scores indicate strong pain-related experiential avoidance. The aim of the current study was to measure pain-related experiential avoidance in a sample of chronic pain patients using the German translation of the AAQ-II­P and to analyze its psychometric qualities. METHODS: After a forward-backward translation procedure of the AAQ-II and adaptation to the pain context, a sample of N = 168 patients from a multidisciplinary pain center answered the German version of the AAQ-II­P. Additional questionnaires were administered to measure specific constructs of interest: chronic pain grade (CPG), pain catastrophizing (PCS), health-related quality of life (SF-12), psychopathology (HADS-D), personality (BFI­K) and mindfulness (KIMS-S). Reliability, factorial validity and construct validity of the AAQ-II­P were identified. RESULTS: The AAQ-II­P had high internal consistency (α = 0.89) and the one-factor solution explained 61% of the total variance. Correlations to personality and mindfulness subscales were low (maxima: r = 0.44 with neuroticism and r = -0.43 with acceptance). High correlations were shown for catastrophizing (r = 0.75), depression (r = 0.73) and anxiety (r = 0.66). Also, there was a substantial correlation to health-related quality of life, specifically the psychological total scale (r = -0.58). DISCUSSION AND CONCLUSION: The German AAQ-II­P has good reliability. Regarding factorial structure and construct validity, it is highly comparable to the original version. Direction and magnitude of the relationship to adjacent constructs mostly measure up to our expectations. Chronic pain patients inclined to pain-related experiential avoidance tend to indicate more pain catastrophizing and show restricted quality of life regarding psychological variables. Apparently, pain-related experiential avoidance can be relevant for popular target variables in psychotherapy.

Swedish Acceptance and Action Questionnaire (SAAQ): a psychometric evaluation.

Psychological inflexibility and experiential avoidance are equivalent (with somewhat different connotations) concepts and refer to an unwillingness to remain in contact with particular private events. This concept is most often measured by the Acceptance and Action Questionnaire (AAQ-II) and is strongly related to psychopathology and behavioral effectiveness. In this study, the preliminary psychometric properties of the Swedish version of the AAQ-II (Swedish Acceptance and Action Questionnaire-SAAQ) are presented. The study is done in two steps. In the first step, the 10-item version of the AAQ-II is investigated through principal component analysis (n = 147). Secondly, due to problems with the component structure, the instrument is reduced to a six-item version and its validity and internal consistency are investigated (n = 154). The six-item version shows good concurrent and convergent validity as well as satisfying internal consistency (α = .85). Furthermore, the Swedish six-item version of the AAQ-II showed one strong component. Test-retest reliability was satisfactory (r = .80; n = 228). In future research, predictive and external validity would be important to investigate in order to further ensure that the SAAQ is a useful measure for clinical research. In conclusion, the SAAQ has satisfactory psychometric properties, but more data need to be gathered to further explore the possibilities for the instruments in Swedish contexts.

Increasing psychological flexibility is associated with positive therapy outcomes following a transdiagnostic ACT treatment.

Objectives: Increasing psychological flexibility is considered an important mechanism of change in psychotherapy across diagnoses. In particular, Acceptance and Commitment Therapy (ACT) primarily aims at increasing psychological flexibility in order to live a more fulfilling and meaningful life. The purpose of this study is to examine 1) how psychological flexibility changes during an ACT-based treatment in a transdiagnostic day hospital and 2) how this change is related to changes in symptomatology, quality of life, and general level of functioning. Methods: 90 patients of a psychiatric day hospital participated in the study. Psychological flexibility, symptomatology, and quality of life were assessed at three measurement time points (admission, discharge, and 3-month follow-up). The level of functioning was assessed at admission and discharge. Differences in psychological flexibility were tested via two-sided paired samples t-tests. Correlations of residualized change scores were calculated to detect associations between changes in psychological flexibility and other outcomes. Results: Psychological flexibility increased significantly from pre-treatment to post-treatment (d = .43, p <.001) and from pre-treatment to follow-up (d = .54, p <.001). This change was significantly correlated to a decrease in symptomatology (r = .60 -.83, p <.001) and an increase in most dimensions of quality of life (r = -.43 - -.75, p <.001) and general level of functioning (r =-.34, p = .003). Discussion: This study adds further evidence for psychological flexibility as a transdiagnostic process variable of successful psychotherapy. Limitations are discussed.

Experiential Avoidance in Primary Care Providers: Psychometric Properties of the Brazilian "Acceptance and Action Questionnaire" (AAQ-II) and Its Criterion Validity on Mood Disorder-Related Psychological Distress.

BACKGROUND: A sizeable proportion of Brazilian Primary Care (PC) providers suffer from common mental disorders, such as anxiety and depression. In an effort to cope with job-related distress, PC workers are likely to implement maladaptive strategies such as experiential avoidance (EA). The Acceptance and Action Questionnaire (AAQ-II) is a widely used instrument that evaluates EA but has shown questionable internal consistency in specific populations. This study assesses the psychometric properties of the AAQ-II among Brazilian PC providers, evaluates its convergence and divergence with self-criticism and mindfulness skills, and explores its criterion validity on anxiety and depressive symptoms. METHODS: A cross-sectional design was conducted in Brazilian PC services, and the sample included 407 PC workers. The measures evaluated EA, self-criticism, mindfulness, depression, and anxiety. RESULTS: The one-factor model of the AAQ-II replicated the original version structure. The AAQ-II presented good internal consistency among Brazilian PC providers. A multiple regression model demonstrated higher relationships with self-criticism than mindfulness skills. The criterion validity of the AAQ-II on anxiety and depression was stronger in the context of more severe symptoms. CONCLUSIONS: The AAQ-II is an appropriate questionnaire to measure the lack of psychological flexibility among Brazilian PC workers in the sense of EA.

A Taxometric Analysis of Experiential Avoidance.

Experiential avoidance, a trait-like construct referring to the tendency to rigidly avoid or change unpleasant internal experiences stemming from an unwillingness to experience them, is believed to contribute to the development and maintenance of various forms of psychopathology. Despite significant research on this construct, it remains unclear whether experiential avoidance is dimensional or categorical at the latent level. The current study examined the latent structure of experiential avoidance using three taxometric analytic approaches (MAXimum Eigenvalue, Mean Above Minus Below A Curve, Latent-Mode Factor Analysis) applied to data from two independent samples and using three widely used measures of experiential avoidance. The first sample (n = 922) completed the Multidimensional Experiential Avoidance Questionnaire (Gámez, Chmielewski, Kotov, Ruggero, & Watson, 2011), while the second sample (n = 615) completed the Brief Experiential Avoidance Questionnaire (Gámez et al., 2014) and Acceptance and Action Questionnaire-II (Bond et al., 2011). Across both samples and all three measures, experiential avoidance exhibited a dimensional structure. The clinical and research implications of this finding for experiential avoidance are discussed.

Psychological Flexibility and Depression in Advanced CKD and Dialysis.

RATIONALE & OBJECTIVE: Depression is prevalent and highly associated with mortality among patients with chronic kidney disease (CKD). Psychological flexibility can be captured as acceptance in psychology, and its improvement by behavioral therapy is associated with reduced depression in some clinical settings. However, no study has been reported on patients with CKD. This study aimed to examine the association between psychological flexibility and depression in patients with CKD. STUDY DESIGN: Cohort study. SETTING & PARTICIPANTS: This multicenter study of 5 hospitals in Japan included patients with nondialysis stage 3-5 CKD or stage 5D CKD receiving hemodialysis or peritoneal dialysis. PREDICTOR: Psychological flexibility measured using the 7-item Acceptance and Action Questionnaire (AAQ-II). OUTCOMES: The prevalence and incidence of depression after 1 year, which was defined by a score ≥ 16 points on the Center for Epidemiologic Studies Depression (CES-D) questionnaire. ANALYTICAL APPROACH: Gamma regression was used in the examination of correlates of the psychological flexibility value. Modified Poisson regression models were fit for the prevalence and incidence of depression. RESULTS: The cross-sectional and longitudinal analyses included 433 and 191 patients, respectively. Lower (ie, worse) psychological flexibility levels were associated with hemodialysis and peritoneal dialysis. Higher (ie, better) psychological flexibility levels were associated with lower prevalence of depression (per 5-point increase; adjusted prevalence ratio, 0.75; 95% CI, 0.70-0.80) and lower incidence of depression (per 5-point increase; adjusted risk ratio, 0.72; 95% CI, 0.61-0.85). LIMITATIONS: Depression was assessed using the CES-D questionnaire. Cultural differences may exist in the interpretation of AAQ-II scores. CONCLUSIONS: Better psychological flexibility was associated with lower prevalence and incidence of depression in patients with CKD. Further studies are warranted to determine the possible prevention and treatment of depression by the development of behavioral interventions to improve psychological flexibility.

Measuring Experiential Avoidance and Posttraumatic Stress in Families.

Experiential avoidance (EA) is receiving attention as an emotion regulation strategy and critical factor in the development and maintenance of posttraumatic stress disorder (PTSD) Evidence suggests that EA explains co-varying relationships among topographically dissimilar problem behaviors. The transmission of emotion regulatory strategies is important to understanding the development of these problems. EA may be a learned response style. This conceptual framework was used to test parent EA as a predictor of young adult/older adolescent (offspring) EA, posttraumatic stress symptoms (PTSS), and problem behaviors in a university context as well as to test the best predictors of these outcomes individually for parents and offspring. Two measures of experiential avoidance, the unwillingness to be in contact with distressing emotions, thoughts, and memories were used to predict the outcomes of interest. The Acceptance and Action Questionnaire-II (AAQ-II) was the strongest and only statistically significant predictor of PTSS and problem behaviors for parents and offspring above and beyond trauma history, while the Multidimensional Experiential Avoidance Questionnaire (MEAQ) remained non-significant. Implications regarding measurement discrepancies, PTSS, and harmful behavior trajectories are discussed.

Abstract Objective. To analyze AAQ-II psychometric properties on the Ecuadorian people. Method. In this study, the psychometric properties of the Acceptance and Action Questionnaire-II (AAQ-II) were evaluated in an Ecuadorian population. A total of 450 people between 18 and 53 years of age, 46.7% of whom were women, participated. Results. The confirmatory factor analysis found a three-dimensional structure: memory avoidance, emotional avoidance, and lack of self-control. An analysis of invariance between men and women revealed that the scale is invariant by sex. The scale was found to have good internal consistency (α = .90). The validity of the AAQ-II as a tool to assess experiential avoidance in an Ecuadorian adult population is discussed.

Experiential Avoidance: An Examination of the Construct Validity of the AAQ-II and MEAQ.

Experiential avoidance (also referred to as acceptance or psychological flexibility) is a core construct of third-wave behavior therapies. It is the tendency to avoid uncomfortable thoughts or feelings, even when doing so has negative long-term consequences. In order for developments in experiential avoidance and third-wave behavior therapies to continue, it is imperative to examine the construct validity of the most widely used measures of this construct, the Acceptance and Action Questionnaire-II (AAQ-II) and the Multidimensional Experiential Avoidance Questionnaire (MEAQ). In Amazon's Mechanical Turk (N = 1,052) and college (N = 364) samples, we evaluated the construct validity of these measures. The AAQ-II demonstrated suboptimal patterns of convergent and discriminant validity with measures of neuroticism/negative affect (Big Five Inventory, Big Five Aspects Scale, Positive and Negative Affect Schedule), the MEAQ, and mindfulness (Five Factor Mindfulness Questionnaire). In contrast, the MEAQ demonstrated optimal convergent and discriminant validity. Factor analyses at the scale, subscale, and item levels demonstrated that the AAQ-II loads with indicators of neuroticism/negative affect and not with other constructs at the core of third-wave behavior therapies. In contrast, the MEAQ loads on factors with mindfulness or forms its own factors. These findings suggest the AAQ-II functions as a measure of neuroticism/negative affect, whereas the MEAQ functions as an indicator of experiential avoidance. These findings have substantial implications for research on experiential avoidance and third-wave behavior therapies. Therefore, in order to improve the theory, research, and practice of third-wave behavior therapies, we recommend using the MEAQ to assess experiential avoidance.

Measuring Experiential Avoidance: Evidence toward Multidimensional Predictors of Trauma Sequelae.

The current study sought to investigate measurement discrepancies in self-report assessment of experiential avoidance (EA). Recent research indicates that EA may be more appropriately conceptualized as a multidimensional construct, operationally defined in terms of specific avoidance strategies. To test this notion, EA was measured using two self-report assessment instruments, the Acceptance and Action Questionnaire-II (AAQ-II) and the Multidimensional Experiential Avoidance Questionnaire (MEAQ) in a convenience sample of university students. Measurement differences across measures and unique contributions to prediction of posttraumatic stress symptoms (PTSS) and engagement in problematic behaviors were evaluated. Both the AAQ-II and MEAQ were found to significantly mediate the effect of childhood trauma exposure on PTSS. However, when levels of PTSS were dummy coded into dichotomies of those with a likely PTSD diagnosis and those without, the MEAQ was a stronger predictor symptoms of those with a likely PTSD diagnosis than AAQ-II did. These results provide initial support for the discriminant validity of the MEAQ, which appears to be a more specific predictor of trauma-related symptoms.

What does the Acceptance and Action Questionnaire (AAQ-II) really measure?

The present study seeks to investigate the extent to which the Acceptance and Action Questionnaire (AAQ-II) is successful in discriminating between experiential avoidance/psychological flexibility on the one hand and the supposed outcomes in terms of psychological well-being of having this trait on the other. This was done using exploratory factor analysis on an item pool containing the AAQ-II items, and items designed for the present study to measure distress and acceptance/non-acceptance, to see what factors are identified and on which factor(s) the AAQ-II items had the highest factor loadings. Interestingly, the analysis found the items of the AAQ-II to be more strongly related to items designed to measure distress than items designed to measure acceptance/nonacceptance with minimal references to functional outcomes. The results of the study are interpreted and discussed in relation to the widespread use of the AAQ in both clinical and scientific contexts and given the centrality of the measure in empirically validating the ACT model of psychopathology and treatment.
