Psychometric evidence of the Acceptance and Action Questionnaire-II (AAQ-II): an item response theory analysis in university students from Chile.

BACKGROUND: Experiential avoidance (EA) is a psychological mechanism associated with several mental health disorders and is regarded as a relevant target by third-generation cognitive behavioral therapies. It has been mainly assessed through self-report questionnaires, and the AAQ-II is the most used tool. Its psychometric evidence has been mostly tested through the classical test theory (CTT) and very scarcely assessed through Item Response Theory (IRT). METHODS: We used the Graded Response Model to examine its psychometric properties in Spanish-speaking university students (n = 1503; women = 995 (66.2%), mean age = 19.29, SD = 2.45). We tested whether the empirical data fit the model's predictions and estimated the dispersion of persons and items along the experiential avoidance continuum. Moreover, we examined category probability curves to identify the response probability of each answer. Likewise, an item-person map was made where the measurement of persons and items, both on the same scale and along the experiential avoidance continuum, could be observed jointly. Finally, we tested the gender invariance of the scale. RESULTS: We found that the values of the individuals and the items were in the established range to be considered an adequate measure of EA. Additionally, we observed high discrimination indices for all items. The current version with seven answer options could not be optimal and should be tested in future studies. Finally, we found evidence of differential functioning by gender in one of the seven items of the instrument. CONCLUSIONS: Our results indicate that the AAQ-II is a suitable tool for measuring EA and accurately classifying and differentiating EA levels in university students.

Active and Passive Facilitation Tendencies at Work Towards Sexy and Professional Women: The Role of Stereotypes and Emotions.

Stereotypes have important social consequences, such as promoting female discrimination in the workplace, which depends on how women are categorized. Extending prior work, here we analyze how two important female subgroups, women who are categorized as professional or sexy women, are evaluated on key dimensions of stereotype content (morality, sociability, and competence), positive and negative emotions, and facilitation behavioral tendencies (active and passive). To this end, we adapted a previous scale of facilitation tendencies to the working environment. Furthermore, we aim to explore the mechanism involved in carrying out helping behaviors towards each subgroup of women in the workplace. In order to fulfill these goals, 201 participants (Mage = 28.88, SD = 12.25; 66.2% women) were randomly assigned to evaluate a woman categorized as either sexy or professional on the mentioned variables. Results show that women categorized as sexy are devalued compared to those categorized as professionals. We also found that competence has a driving role in predicting more active facilitation tendencies towards a woman categorized as professional than a woman categorized as sexy via positive emotions. These findings have implications for the career development of women.

Scale of psychological pain: Spanish adaptation of the Psychache Scale in young adults.

INTRODUCTION: Psychological pain is understood as an intolerable and disturbing mental state characterized by an internal experience of negative emotions. This study was aimed at making a Spanish adaptation of the Psychache Scale by Holden and colleagues in a sample of young adults. MATERIAL AND METHODS: The scale evaluates psychological pain as a subjective experience. It is composed of 13 items with a Likert-type response format. Following the guidelines of the International Tests Commission for the adaptation of the test, we obtained a version conceptually and linguistically equivalent to the original scale. Through an online questionnaire, participants completed the psychological pain scale along with other scales to measure depression (BDI-II), hopelessness (Beck's scale of hopelessness) and suicide risk (Plutchik suicide risk scale). The participants were 234 people (94 men, 137 women and three people who identified as a different sex) from 18 to 35 years old. RESULTS: The EFA showed a one-factor solution, and the FCA revealed adequate indexes of adjustment to the unifactorial model. It also showed good reliability of the test scores. The evidence of validity of the scale in relation to the other variables showed high, positive and statistically significant correlations with depression, hopelessness, suicidal ideation and suicidal risk. CONCLUSION: In summary, this Spanish adaptation of the Psychache Scale could contribute to improving the evaluation of both the patient with suicide risk and the effectiveness of psychological therapy, as well as suicidal behaviour prevention and intervention.

[Psychometric properties of the Generalized Anxiety Disorder 7-item (GAD-7) scale in Chilean adolescents]. / Propiedades psicométricas de la escala Generalized Anxiety Disorder 7-Item (GAD-7) en una muestra comunitaria de adolescentes en Chile.

BACKGROUND: The Generalized Anxiety Disorder 7-item (GAD-7) scale is widely used for the assessment of generalized anxiety disorder. AIM: To adapt the GAD-7 to the Chilean adolescent population and to evaluate its psychometric properties. MATERIAL AND METHODS: The GAD-7 was adapted and administered to 2,022 adolescents between 13 and 19 years of age, recruited from eight schools in the northern area of Santiago, Chile. Other self-report instruments were used to assess depressive symptoms and health-related quality of life. The one factor structure and invariance by sex were examined using Confirmatory Factor Analysis. Its reliability and validity based on its relationship with other variables were assessed. RESULTS: The one-factor structure and invariance by sex were confirmed. The results showed an adequate internal reliability (Cronbach's alpha = 0.86, Spearman-Brown coefficient = 0.82). As expected, significant correlations were observed with measures of depressive symptoms and health-related quality of life. Higher scores were observed in women than in men. CONCLUSIONS: The Chilean version adapted for adolescents of the GAD-7 has good psychometric properties. Thus, it may be a useful and valid instrument for the assessment of generalized anxiety disorder in adolescents in Chile.

Psychosocial Variables and Healthcare Resources in Patients with Fibromyalgia, Migraine and Comorbid Fibromyalgia and Migraine: A Cross-Sectional Study.

Fibromyalgia and migraine frequently coexist. We aimed to compare the burden caused by fibromyalgia (FM), migraine (M) and comorbid fibromyalgia and migraine (FM + M) by assessing psychosocial variables and the use of healthcare resources. A survey was posted to the websites of different patients' associations. It included sociodemographic data, the Patient Health Questionnaire-9, the Insomnia Severity Index, the EuroQOL-5D-5L and a questionnaire evaluating the use of healthcare resources during the past six months. In total, 139 FM patients, 169 M patients and 148 FM + M patients participated in the survey. Mean depression and insomnia scores were clinically relevant in every group and significantly higher in FM + M (16.3 ± 5.4 for depression, 18.5 ± 5.6 for insomnia) than in FM (14.3 ± 5.7 for depression, 16.8 ± 5.5 for insomnia) or M (11.7 ± 5.4 for depression, 13.1 ± 5.9 for depression), where p < 0.001 in both cases. Suicidal ideation was frequent in every group, but significantly more frequent in FM + M (63% vs. 45% in FM and 35% in M; p < 0.001). EQ-5D-5L (0.656 ± 0.1 in FM + M, 0.674 ± 0.1 in FM, 0.827 ± 0.1 in M, p < 0.001) and EQ-5D-5L VAS scores (38.2 ± 21.9 in FM + M, 45.6 ± 21.8 in FM, 63.5 ± 23.7 in M, p < 0.00) were lower than the reported mean population values and the lowest in FM + M. FM and FM + M used more healthcare resources than M. It is concluded that the psychosocial burden was high in the three samples. FM and FM + M had a more relevant impact on patients' wellbeing and required more medical attention than M. The burden caused by FM + M was higher than in both individual diseases.

Frustrated interpersonal needs as a motivational moderator in the integrated motivational-volitional model.

A theoretical assumption of the integrated motivational-volitional (IMV) model positions perceived burdensomeness (PB) and thwarted belongingness (TB) as moderators on the entrapment-suicidal ideation/intention relationship. The present study analyzed the expected combined effects of PB × TB on the relationship between entrapment and suicidal ideation/intention. Data were collected using an online questionnaire (N = 644) selected by sex, age, and education level. The PB × TB × Entrapment interaction was statistically significant, according to a moderating effect. A high degree of frustration of interpersonal needs enhances the entrapment-suicidal ideation/intention relationship.

Experiential avoidance mediates the association between paranoid ideation and depressive symptoms in a sample from the general population.

Psychotic experiences are prevalent in the general population and are associated with negative outcomes, including depressive symptoms. The mechanisms underlying this relationship remain unclear, but new insights could be obtained by exploring the role of transdiagnostic processes such as experiential avoidance, defined as a person's attempts or desires to suppress unwanted internal experiences like thoughts, emotions, memories, or bodily sensations. Studies analyzing the link between negative emotional states and psychotic experiences are scant. We explored the association between a specific kind of psychotic experience (paranoid ideation), experiential avoidance, and depressive, anxiety, and stress symptoms in a sample from the general population. We found that experiential avoidance partially mediates the associations between paranoid ideation and stress and anxiety symptoms and that it fully mediates the association between paranoid ideation and depressive symptoms. Our results suggest that the presence of paranoid ideation and the usage of experiential avoidance to cope with it are vulnerability factors associated with psychological distress.

Marital adjustment in patients with fibromyalgia: its association with suicidal ideation and related factors. A cross-sectional study.

OBJECTIVES: Fibromyalgia has been associated with suicidal ideation, suicide attempts and completed suicide. Non-married status is a risk factor for suicidal behaviours but the quality of the marital relationship has been scarcely investigated. The objectives of the present study were to evaluate, in patients with fibromyalgia, the relationship between marital adjustment suicidal ideation and potentially related variables: depression severity, sleep disturbance, perceived burdensomeness, thwarted belongingness, fibromyalgia severity and pain intensity. METHODS: A survey was done in patients with fibromyalgia which collected sociodemographic data and included the following questionnaires: the Locke and Wallace Marital Adjustment Test, the Beck's Depression Inventory II, the Plutchik Suicide Risk Scale, a 10-item version of the Interpersonal Needs Questionnaire, the Insomnia Severity Index, and the Revised Fibromyalgia Impact Questionnaire. Suicidal ideation was assessed with item 9 of the Beck's Depression Inventory, and pain intensity was measured with the VAS scale of the Revised Fibromyalgia Impact Questionnaire. RESULTS: Of 257 participants 71 were single, 107 had a good marital adjustment and 79 a poor marital adjustment. Suicidal ideation was most frequent among patients with poor marital adjustment than among those with good marital adjustment or patients without partner. The poor marital adjustment group showed significantly worse scores in most of the remaining variables with the only exceptions of the FIQR and pain scores. CONCLUSIONS: In patients with fibromyalgia the degree of marital adjustment seems to be a relevant factor for suicidal ideation and related variables.

Adaptación al español de las escalas de derrota y atrapamiento en jóvenes adultos: propiedades psicométricas / Adaptation to spanish of the scales of defeat and entrapment in young adults: psychometric properties

Resumen: Antecedentes: El Modelo Integrado Motivacional-Volitivo contempla la ideación suicida como una reacción psicológica a una situación que se percibe como una derrota junto a la percepción de estar atrapado/a y sin posible escape ni rescate. Objetivo: El presente estudio tiene como objetivo adaptar al contexto español y analizar las propiedades psicométricas de dos escalas, una para medir derrota y otra para medir atrapamiento. Método: Doscientas treinta y cuatro personas de 18-35 años (58,6% mujeres) completaron un cuestionario online. Resultados: El análisis de la estructura interna mostró una solución bifactorial para la escala de derrota y una solución unifactorial para la escala de atrapamiento, ambas con adecuados índices de ajuste. Además, mostraron buena fiabilidad de las puntuaciones de los test y evidencias favorables de validez. Conclusiones: Disponer de ambas escalas adaptadas contribuye a mejorar la evaluación del riesgo suicida, así como a orientar la intervención y realizar aportaciones en el campo de la suicidología.

Abstract: Background: The Integrated Motivational-Volitional Model contemplates suicidal ideation as a psychological reaction to a situation that is perceived as a defeat along with the perception of being trapped and without possible escape or rescue. Aim: The present study aims to adapt to the Spanish context and analyze the psychometric properties of two scales, one to measure defeat and another to measure entrapment. Method: Two hundred and thirty-four people aged 18-35 years (58.6% women) completed an online questionnaire. Results: The analysis of the internal structure showed a bifactorial solution for the scale of defeat and a unifactorial solution for the scale of entrapment, both with adequate adjustment indexes. In addition, they showed good reliability of the test scores and favorable evidence of validity. Conclusions: Having both scales adapted helps to improve the assessment of suicide risk, as well as to guide the intervention and make contributions in the field of suicide.

Experiential Avoidance in the Context of the Integrated Motivational-Volitional Model of Suicidal Behavior.

Background: According to the integrated motivational-volitional model of suicide, the perception of defeat and entrapment are the variables involved in the development of suicidal ideation. However, entrapment is not an inevitable consequence of feeling defeated. This transition is moderated by a set of variables relating to the ability to resolve the state of defeat. Aim: We aimed to study the potential moderating role of experiential avoidance in the relationship between defeat and entrapment in young adults. Method: A sample of 644 participants residing in Spain (51.2% female; Mage = 25.91, SDage = 5.14; range = 18-35 years old), selected by sex, age, and education level quotas, completed an online questionnaire consisting of: Defeat Scale; Entrapment Scale; and Acceptance and Action Questionnaire-II; and other sociodemographic variables. Results: Defeat and experiential avoidance had a statistically significant effect on entrapment. The interaction variable (defeat × experiential avoidance) was also statistically significant according to a moderating effect. Limitations: Due to the cross-sectional design, we could not establish causal associations between the variables. Conclusion: People who experience a high degree of defeat and experiential avoidance are more likely to progress to a state of entrapment, being more vulnerable to having suicidal ideation.

Profiles of patients with cocaine and alcohol use disorder based on cognitive domains and their relationship with relapse.

BACKGROUND: Relapse in drug use constitutes a research topic on addiction that is relevant for understanding both the addictive process and its clinical implications. The objective of this study was to explore if it is possible to identify patient profiles according to their performance on cognitive tasks whilst examining the relationship between such profiles and relapse. METHODS: The sample consisted of 222 patients with dependence on cocaine and / or alcohol, of which 86 % were men. Cognitive domains related to salience, decision- making, and emotional processing were measured. RESULTS: Latent class analysis revealed three patient profiles that differ in terms of performance on cognitive tasks. Two of these profiles are clearly differentiated in terms of their execution of the impulsive decision-making task. The third patient profile, unlike the latter two, is composed of patients with severe alterations in the three domains evaluated. Analysis revealed that patients in Profile 3 are those with the highest rates of relapse in cocaine (Profile 1 = 40.3 %; Profile 2 = 35.6 %; Profile 3 = 69.2 %; Chi2 = 9.169; p < .05) and cocaine and alcohol use (Profile 1 = 55.1 %; Profile 2 = 54.1 %; Profile 3 = 80 %; Chi2 = 6.698; p < .05). CONCLUSIONS: The results support the postulates of the I-RISA model. From a clinical perspective, these findings highlight the need for a comprehensive evaluation of the cognitive domains involved in addiction.

Stigmatizing Beliefs and Attitudes to Depression in Adolescent School Students in Chile and Colombia.

Major depressive disorder (MDD) affects between 4 and 5% of adolescents. However, there is still a huge gap between adolescents who meet criteria for MDD and those who receive mental health care. Stigmatizing attitudes toward depression are among the main barriers to seeking professional help. The aim of this article is to examine the individual characteristics associated with stigmatizing attitudes toward depression in a sample of adolescent school students from Chile and Colombia, and present the adaptation and psychometric properties of the Personal Depression Stigma Scale (DSS-Personal) for both countries. A total of 2971 adolescents, aged 10-19 (M = 14.6, SD = 1.5), who were recruited from eight schools in Santiago, Chile (n = 2022), and eight schools in Medellín, Colombia (n = 949), completed the DSS-Personal, the Patient Health Questionnaire (PHQ-9), and a questionnaire of individual sociodemographic characteristics. Factor structure, internal consistency, and validity of the DSS-Personal were assessed. Multiple linear regression models were used to evaluate the association between DSS-Personal scores and sociodemographic information, depression scores, and the use of health services by country. Confirmatory factor analysis supported the unidimensional structure of the DSS-Personal, while the estimated reliability of its scores was acceptable. Results show that DSS-Personal scores were higher in adolescents in Colombia than in Chile (U = 9.36, p < 0.001). Immigrant status was the only variable significantly related to personal depression stigma in both samples. Being female was associated with lower levels of stigma in adolescents in Chile, while depressive symptoms were associated with lower levels of stigma in adolescents in Colombia. Age, having been diagnosed with depression, and being in pharmacological or psychological treatment were not related to levels of personal depression stigma in either sample. The identified associated factors of personal depression stigma should be considered in the development of anti-stigma campaigns; also, gender differences require special attention. The results of this study suggest that it is important to offer school-based programs to reduce personal stigma, and that specific anti-stigma campaigns should address personal stigma in men and immigrants.

Patterns of pharmacologic and non-pharmacologic treatment, treatment satisfaction and perceived tolerability in patients with fibromyalgia: a patients' survey.

OBJECTIVES: To evaluate the patterns of treatment among patients with fibromyalgia (FM) in Spain and to assess patient satisfaction and perceived tolerability of the treatment received. METHODS: An observational, cross-sectional study was conducted in Spain via internet from September 2015 to March 2017. We recorded sociodemographic and clinical information, including treatment satisfaction evaluated using a 10-point numerical rating scale (NRS) and adverse events. RESULTS: Evaluable subjects (n=915) were predominantly middle-aged, married women who presented with moderate to severe pain, sleep disturbance and affected quality-of-life. The most frequent non-pharmacologic treatments were physical exercise (85%), diet (47%), supplements such as magnesium and vitamins (47%), and psychotherapy (31%). The most frequently prescribed drugs were tramadol (40%), benzodiazepines (30%), duloxetine (22%), pregabalin (19%), amitriptyline (17%) and nonsteroidal anti-inflammatory drugs (NSAIDs; 16%); 7.5% of patients received stronger opioids. After excluding benzodiazepines, NSAIDs, and paracetamol, 46% of patients received ≥2 drugs. Satisfaction with treatment (NRS mean score) was generally poor for pharmacologic treatment (4.1), exercise (4.7), psychotherapy (5.2), diet (5.0), physiotherapy (6.2) and acupuncture (6.3). The increase in the number of drugs prescribed was not associated with an increase in satisfaction, but rather with an increase in adverse events. CONCLUSIONS: Patients with FM in Spain are overtreated with a combination of non-pharmacologic and pharmacologic therapies. Several of these therapies lack adequate support from randomised clinical trials and/or clinical practice guidelines. This overtreatment is not associated with relevant clinical benefits or patient satisfaction and, in the case of pharmacologic treatments, poses tolerability and safety issues.

Suicidal Ideation Profiles in Patients with Fibromyalgia Using Transdiagnostic Psychological and Fibromyalgia-Associated Variables.

Several studies have emphasized the heterogeneity of fibromyalgia patients. Furthermore, fibromyalgia patients are considered a high-risk suicide group. The ideation-to-action framework proposes a set of transdiagnostic psychological factors involved in the development of suicidal ideation. The present study aims to explore the existence of different subgroups according to their vulnerability to suicidal ideation through these transdiagnostic psychological variables and a set of variables typically associated with fibromyalgia. In this cross-sectional study, 151 fibromyalgia patients were assessed through the Revised Fibromyalgia Impact Questionnaire, Beck Depression Inventory-II, Plutchik Suicide Risk Scale, Interpersonal Needs Questionnaire, Defeat Scale, Entrapment Scale, Psychache Scale, and Beck Hopelessness Scale. A K-means cluster analysis identified two clusters, one (45.70%) according to a low vulnerability, and a second (54.30%) with a high vulnerability to suicidal ideation. These clusters showed statistically significant differences in suicidal ideation and suicide risk. However, no differences were observed in most socio-demographic variables. In conclusion, fibromyalgia patients who present a clinical condition characterized by a moderate-high degree of physical dysfunction, overall disease impact and intensity of fibromyalgia-associated symptoms, along with a high degree of perceived burdensomeness, thwarted belongingness, defeat, entrapment, psychological pain and hopelessness, form a homogeneous group at high risk for suicidal ideation.

The evidence of validity of the scale in relation to the other variables showed high, positive and statistically significant correlations with depression, hopelessness, suicidal ideation and suicidal risk. CONCLUSION: In summary, this Spanish adaptation of the Psychache Scale could contribute to improving the evaluation of both the patient with suicide risk and the effectiveness of psychological therapy, as well as suicidal behaviour prevention and intervention.

Perceived burdensomeness, thwarted belongingness and suicidal ideation in patients with fibromyalgia and healthy subjects: a cross-sectional study.

Perceived burdensomeness and thwarted belongingness are key factors in the development of suicidal behaviors that have been frequently observed among patients with fibromyalgia. The aim of the present study was to compare these two factors in patients with fibromyalgia with and without suicidal ideation and healthy subjects. Secondary objectives were to evaluate the relationship between these two factors and the secondary variables included in the study, such as depression, sleep quality or the degree of marital adjustment. Perceived burdensomeness and thwarted belongingness were assessed with the Interpersonal Needs Questionnaire, depression and suicidal ideation with the Patients Health Questionnaire-9, suicidal risk with the Plutchik Suicide Risk scale, sleep with the Insomnia Severity Index, and marital adjustment with the Locke-Wallace Marital Adjustment scale. Questionnaire scores were compared with the Kruskal-Wallis test. 49 healthy subjects, 38 patients with fibromyalgia without suicidal ideation and 15 patients with fibromyalgia and suicidal ideations were included. Perceived burdensomeness scores were significantly higher in patients with suicidal ideation than in patients without suicidal ideation and controls; thwarted belongingness scores were significantly higher in patients with suicidal ideation than in controls. Marital adjustment was also significantly poor in patients with suicidal ideation than in patients without suicidal ideation and controls. Among patients with fibromyalgia, perceived burdensomeness seems to be strongly related with suicidal ideation, whereas thwarted belongingness seems to play a less relevant role at this respect. Poor marital adjustment could be related with depression.

Psychometric properties of the Spanish version of the 12-item Interpersonal Needs Questionnaire in fibromyalgia syndrome patients / Propiedades psicométricas de la versión en español del Cuestionario de Necesidades Interpersonales de 12 ítems en pacientes con síndrome de fibromialgia

According to the interpersonal theory of suicide, thwarted belongingness and perceived burdensomeness are key elements in the development of suicidal ideation. The Interpersonal Needs Questionnaire (INQ) was developed to assess the degree of frustration of these two interpersonal needs related to suicidal ideation. This study aims to analyze the psychometrics properties of a Spanish adaptation of INQ-12 in fibromyalgia patients. Exploratory factor analysis (n = 180) and confirmatory factor analysis (n = 179) were performed in two randomly selected subsamples. The first analysis leads to the elimination of two items, whereas the second one confirmed the fit of the proposed two-factor structure. The reliability estimated using the Cronbach's alpha coefficient and the Spearman-Brown coefficient was adequate. To obtain further validity evidence based on the relationship with other variables three variables were used. Moreover, a control group (n = 99) was used to contrast the means of INQ scores as evidence of validity based on differential scores. These findings support the usefulness of the Spanish version of the INQ-10 for assessing the degree of frustration of these interpersonal needs in patients with fibromyalgia

Según la teoría interpersonal del suicidio, la pertenencia frustrada y la carga percibida son elementos clave en el desarrollo de la ideación suicida. El Cuestionario de necesidades interpersonales (INQ) fue diseñado para evaluar el grado de frustración de estas dos necesidades interpersonales relacionadas con la ideación suicida. El objetivo de este estudio fue analizar las propiedades psicométricas de una adaptación al español del INQ-12 en pacientes con fibromialgia. Un análisis factorial exploratorio (n = 180) y un análisis factorial confirmatorio (n = 179) fueron realizados en dos submuestras seleccionadas al azar. El primer análisis llevó a la eliminación de dos ítems, mientras que el segundo confirmó el ajuste de la estructura propuesta de dos factores. La fiabilidad estimada mediante el coeficiente alfa de Cronbach y el coeficiente Spearman-Brown fue adecuada. Para obtener evidencias de validez basadas en la relación con otros variables, se utilizaron tres variables relacionadas con el suicidio. Además, se utilizó un grupo control (n = 99) para contrastar los promedios de las puntuaciones INQ como evidencia de validez basada en puntajes diferenciales. Estos hallazgos respaldan la utilidad de la versión española del INQ-10 para evaluar el grado de frustración de estas necesidades interpersonales en pacientes con fibromialgia
