International application of the "Multidimensional Intervention for Social Anxiety" (MISA) program: II. Treatment effectiveness for social anxiety-related problems

This study is part of the I+D+i project with reference RTI2018-093916-B-I00, funded by MCIN/AEI/10.13039/501100011033/and FEDER "A way of doing Europe". Support from the Foundation for the Advancement of Clinical Behavioral Psychology (FUNVECA) is also acknowledged.In a previous work (Caballo et al., 2021) we tested the effectiveness of the Multidimensional Intervention for Social Anxiety (MISA) program in reducing social anxiety symptoms. In this quasi-experimental study, with pre/post-treatment and follow-up measures, we examined the impact of the MISA program on other problems related to social anxiety. 57 people diagnosed with social anxiety disorder (SAD), according to DSM-5, were assessed with a diagnostic interview and questionnaires measuring social skills, depression, avoidant personality disorder symptoms, alcoholism, self-esteem, personal sensitivity, worries, and quality of life. Different therapists carried out the treatment in Ecuador, Spain, and Paraguay. The results showed significant improvements at post-treatment in virtually all measures assessing the above variables, improvements that were maintained at six months. Effect sizes on treatment effectiveness ranged from medium to large. The MISA program was also compared with individual cognitive behavioral therapy and pharmacological treatment, with favorable results for the MISA program. In conclusion, this new program for the treatment of social anxiety has a significant impact on other problems usually related to SAD.In a previous work (Caballo et al., 2021) we tested the effectiveness of the Multidimensional Intervention for Social Anxiety (MISA) program in reducing social anxiety symptoms.

Psychometric properties of the Liebowitz Social Anxiety Scale in a large cross-cultural Spanish and Portuguese speaking sample

[EN]Two groups of participants were included: a non-clinical sample involving 31,243 community subjects and a clinical sample comprising 529 patients with a diagnosis of social anxiety disorder (SAD). Exploratory factor analysis (EFA), confirmatory factor analysis (CFA) and exploratory structural equation modeling (ESEM) were used in order to determine the psychometric properties of the LSAS-SR. EFA identified five factors with eigenvalues greater than 1.00 explaining 50.78% of the cumulative variance. CFA and ESEM supported this 5-factor structure of the LSAS-SR. The factors included: 1) speaking in public; 2) eating/drinking in front of other people; 3) assertive behaviors; 4) working/writing while being observed; and 5) interactions with strangers. Other psychometric properties such as inter-factor correlations, invariance, reliability, and validity of the scale were also foun

Moral Disengagement Mechanisms, Sex Differences, and Clinical Predictors in Adolescents: An Exploratory Study

La desconexión moral es un constructo útil para explicar el comportamiento disruptivo en la adolescencia, evidenciando diferencias entre hombres y mujeres. Sin embargo, no existen estudios respecto de la asociación de factores clínicos y psicológicos y el uso de mecanismos de desconexión moral. Por tal motivo, este estudio analizó las diferencias de sexo y predictores clínicos de los mecanismos de desconexión moral en adolescentes. Se utilizó una metodología cuantitativa, no experimental, transversal y explicativa, con la participación de 354 adolescentes entre 14 y 18 años (M = 15,58, DE = 1,22) de dos instituciones educativas de Manizales, Colombia. Se utilizó el cuestionario de desconexión moral (MMDS) y las escalas de autoestima (RSES), impulsividad (BIS-11), desesperanza (BHS), ansiedad (BAI) y depresión (BDI). Una prueba t de Student mostró que los hombres presentan puntuaciones más altas que las mujeres en todos los mecanismos de desconexión moral. Un análisis de regresión lineal múltiple por sexo también reveló que la impulsividad tuvo un efecto sobre la desconexión moral en hombres, mientras que las variables impulsividad, desesperanza y ansiedad evidenciaron los efectos más altos que explican la desconexión moral en mujeres. El modelo de regresión lineal múltiple evidenció que la impulsividad y el sexo presentaron los efectos más altos en la predicción de la desconexión moral y sus mecanismos. Se considera que los resultados aportan explicaciones teóricas novedosas en una línea de investigación que pretende relacionar las perspectivas psicológicas, clínicas y cognitivo-sociales con implicaciones importantes para la intervención psicosocial en adolescentes.Moral disengagement is a useful construct for explaining disruptive behavior in adolescents, revealing differences between men and women. However, no research has been conducted on the association between clinical and psychological factors and the use of moral disengagement mechanisms. For this reason, this study analyzed sex differences and clinical predictors of moral disengagement mechanisms in teenagers. A quantitative, non-experimental, cross-sectional, and explanatory methodology was used. The participants were 354 adolescents between 14 and 18 years of age (M = 15.58, SD = 1.22) from two educational institutions in Manizales, Colombia. The moral disengagement scale (MMDS) was used along with self-esteem (RSES), impulsivity (BIS-11), despair (BHS), anxiety (BAI), and depression scales (BDI). A Student's t-test showed that men scored higher than women on all moral disengagement mechanisms. A multiple linear regression analysis by sex also revealed that impulsivity had an effect on moral disengagement in men, whereas the variables impulsivity, despair, and anxiety showed the highest effects explaining moral disengagement in women. The multiple linear regression model showed that impulsivity and sex had the strongest effects on the prediction of moral disengagement and its mechanisms. The results are considered to offer innovative theoretical explanations in a line of research aimed at linking psychological, clinical, and cognitive-social perspectives, with major implications for psychosocial intervention in adolescents.Universidad Católica Luis Amigó, Colombi

En cuanto a la estabilidad temporal, no se observó ningún cambio en el grupo control. Con respecto a la sensibilidad al cambio, el grupo experimental presentó mayor autoeficacia a lo largo del seguimiento. Conclusiones: Los resultados preliminares mostraron niveles adecuados de validez y fiabilidad, demostrando ser una escala útil para evaluar la autoeficacia relacionada a la alimentación.Introduction: The aim of this study was to describe the preliminary psychometric properties of the “Self-Efficacy to Regulate Eating Habits (SEREH)”. Material and Methods: Participated in a randomized clinical trial for lifestyle modification 135 subjects with metabolic syndrome, who were divided into two groups (e.g., experimental and control), in a 18-months follow-up. The evaluation included anthropometric, clinical, psychological and lifestyle data. To verify the validity and reliability, a factorial analysis was performed, as well as analyses of the internal consistency, temporal stability, sensitivity to change, and convergent validity. Results: A solution with two factors was extracted, which explained 60.97% of the variance of the SEREH. The internal consistency for the total score was 0,971 - Cronbach’s alpha. Regarding temporal stability, no changes were observed during the follow-up in the control group. With regard to sensitivity to change, the experimental group showed greater self-efficacy than did the control group during the follow-up. Conclusions: These preliminary results showed adequate psychometric properties of the scale, demonstrating that this is a valid and reliable scale for assessing self-efficacy related to food behaviors.El presente trabajo ha sido financiado por el Ministerio de Educación de Brasil (Fundación Capes) [beca número 5566- 10-0]

Scales for social support for eating habits and exercise: psychometric properties

Fundamentos: El apoyo social puede introducir cambios favorables en el estilo de vida de cara a reducir el riesgo cardiovascular. El objetivo de este estudio fue verificar dichos cambios en la población clínica que participó en el mismo y presentar las propiedades psicométricas de dos escalas de apoyo social: los hábitos alimentarios y el ejercicio. Ambas fueron aplicadas en pacientes con síndrome metabólico (SM). Métodos: Participaron 135 sujetos en un programa de modificación de estilo de vida. Las medidas sociodemográficas, psicológicas y de estilo de vida fueron tomadas en el Hospital Universitario Virgen de las Nieves (HUVN) de Granada (España) durante 2013 y 2014. Se realizaron los siguientes análisis: análisis factorial confirmatorio (AFC), de la consistencia interna, de la sensibilidad al cambio y de la estabilidad temporal. Resultados: El AFC confirmó la estructura original de ambas escalas, excepto por la exclusión del factor 2 (familia) de la escala de apoyo social para el ejercicio. Para la escala de apoyo social, el ajuste local, todos los ítems presentaron altos valores de cargas factoriales y fiabilidades individuales (λ≥0,64 y R2≥0,41, respectivamente). Para la escala de ejercicio, el ajuste local, los ítems presentaron altos valores de cargas factoriales y fiabilidades individuales (λ≥0,62 y R2≥0,38, respectivamente). Los valores de consistencia interna resultaron entre adecuados y excelentes, con cifras de alfa de Cronbach entre 0,714 y 0,864. En cuanto a la sensibilidad al cambio, el grupo experimental aumentó la percepción del apoyo social para la alimentación y para el ejercicio. El grupo de control no presentó diferencias significativas. Conclusiones: Los resultados muestran niveles adecuados de validez y fiabilidad, demostrando que las escalas son adecuadas para evaluar el apoyo social en pacientes con SM.Background: Social support can introduce favorable changes in lifestyle to reduce the cardiovascular risk. The aim of this study was to verify these changes in the clinical population participating in this study and present the psychometric properties of the scales of social support for ‘Eating Habits’ and ‘Exercise’ in patients diagnosed with metabolic syndrome. Methods: 135 participants attending a programme for changing lifestyle habits. Sociodemographic, psychological, and lifestyle variables were assessed at the Hospital Universitario Virgen de las Nieves (HUVN) in Granada (Spain) between 2013 and 2014. The following procedures were used: Confirmatory factor analysis (CFA), internal consistency, sensibility to change and temporal stability. Results: The AFC confirmed the original structure of both scales, except for the exclusion of factor 2 (family) from the social support scale for the year. For the social support scale, the local adjustment, all items presented high values of factor loads and individual reliability (λ≥0.64 and R2≥0.41, respectively). For the exercise scale, the local adjustment, the items presented high values of factor loads and individual reliability (λ≥0.62 and R2≥0.38, respectively). Internal consistency values were between adequate and excellent, with Cronbach’s alpha figures between 0.714 and 0.864. Regarding sensitivity to change, the experimental group increased the perception of social support for food and exercise. The control group did not show significant differences. Conclusions: Our results show adequate indices for validity and reliability of the measures. Both measures appeared to be useful to assess social support in patients diagnosed with metabolic syndrome

Validez y fiabilidad de la escala de autoeficacia para el ejercicio físico en pacientes con síndrome metabólico

Self-efficacy refers to beliefs in individuals’ own capac-ities to do something. With the intent of evaluate the validity and reliability, we investigated the psychometric properties of the Self-Efficacy to Regulate Exercise Scale (SERES) in patients with metabolic syndrome (MetS).Methods: 135 participants with medical diagnosis of MetS took part in the study (Mage=55.5, SD=7.6). We investigated sociodemographic, psycho-logical, and life-style variables. Participants were recruited at the Hospital Universitario Virgen de las Nieves (HUVN) in Granada (Spain) between 2013 and 2014. In order to characterise the sample, descriptive statistics were used. Factorial analysis, internal consistency and convergent reliability of the SERES were also calculated. Group differences were investigated using Student’s t test.Results: A solution with two factors was extracted, which explained 72.7% of the variance of the SERES. The internal consistency values for the total score of the SERES were (0.925 and 0.864) according to the values of Cronbach’s alpha and Guttman’s two halves, respectively. Significant corre-lations of the SERES were detected for with physical exercise, assertiveness, stress, anger, and active life-style (e.g., renouncing to sedentary behaviours) Conclusions: This was the first study to report on psychometric prop-erties of the SERES. Results supported the adequacy of the measure for use with patients with MetS. SERES seemed to be useful in evaluating self-ef-ficacy in relation to physical exercise, psychosocial, and lifestyle variables.Fundamentos: La autoeficacia percibida se refiere a la creencia en la propia capacidad para hacer algo. El objetivo de este trabajo fue obtener la validez y la fiabilidad de la escala de autoeficacia para el ejercicio físico (AEEF) en pacientes con síndrome metabólico (SM) y para ello fueron veri-ficadas las propiedades psicométricas de la misma. Métodos: Participaron en el estudio 135 sujetos con una edad media de 55,5 años (DT=7,6) que cumplían los criterios diagnósticos para el SM. Se tomaron medidas sociodemográficas, psicológicas y de estilo de vida de los mismos. Los sujetos fueron reclutados en el Hospital Universitario Virgen de las Nieves (HUVN) de Granada (España) durante los años de 2013 a 2014. La caracterización de la muestra fue realizada a través de análisis descriptivos. Se realizó el análisis factorial, de la consistencia interna y de validez convergente del AEEF; las diferencias intra e intergrupales fueron evaluadas a través de la prueba t de Student. Resultados: Extrajimos una solución de 2 factores que explicaron el 72,7% de la varianza común. Los valores de consistencia interna para la puntuación total de la AEEF fueron de (0,925 y 0,864) según los valores del alfa de Cronbach y del método de las dos mitades de Guttman, respec-tivamente. Las correlaciones de la AEEF con la frecuencia de la práctica de ejercicios, la renuncia al sedentarismo, la asertividad, el estrés y la ira fueron estadísticamente significativasConclusiones: Este es el primer estudio sobre las propiedades psi-cométricas de la versión española de la AEEF. Los resultados mostraron niveles aceptables de validez y fiabilidad en pacientes con SM. La escala demostró ser útil para evaluar la asociación de la autoeficacia relativa al ejercicio físico con distintas variables psicosociales y de estilo de vida

The Northern ROSAT All-Sky (NORAS) Galaxy Cluster Survey I: X-ray Properties of Clusters Detected as Extended X-ray Sources

In the construction of an X-ray selected sample of galaxy clusters for cosmological studies, we have assembled a sample of 495 X-ray sources found to show extended X-ray emission in the first processing of the ROSAT All-Sky Survey. The sample covers the celestial region with declination $\delta \ge 0\deg$ and galactic latitude $|b_{II}| \ge 20\deg$ and comprises sources with a count rate $\ge 0.06$ counts s$^{-1}$ and a source extent likelihood of 7. In an optical follow-up identification program we find 378 (76%) of these sources to be clusters of galaxies. ...Comment: 61 pages; ApJS in press; fixed bug in table file; also available at (better image quality) http://www.xray.mpe.mpg.de/theorie/NORAS

Pre-Flight Calibration of the Mars 2020 Rover Mastcam Zoom (Mastcam-Z) Multispectral, Stereoscopic Imager

The NASA Perseverance rover Mast Camera Zoom (Mastcam-Z) system is a pair of zoomable, focusable, multi-spectral, and color charge-coupled device (CCD) cameras mounted on top of a 1.7 m Remote Sensing Mast, along with associated electronics and two calibration targets. The cameras contain identical optical assemblies that can range in focal length from 26 mm (25.5∘×19.1∘ FOV) to 110 mm (6.2∘×4.2∘ FOV) and will acquire data at pixel scales of 148-540 μm at a range of 2 m and 7.4-27 cm at 1 km. The cameras are mounted on the rover’s mast with a stereo baseline of 24.3±0.1 cm and a toe-in angle of 1.17±0.03∘ (per camera). Each camera uses a Kodak KAI-2020 CCD with 1600×1200 active pixels and an 8 position filter wheel that contains an IR-cutoff filter for color imaging through the detectors’ Bayer-pattern filters, a neutral density (ND) solar filter for imaging the sun, and 6 narrow-band geology filters (16 total filters). An associated Digital Electronics Assembly provides command data interfaces to the rover, 11-to-8 bit companding, and JPEG compression capabilities. Herein, we describe pre-flight calibration of the Mastcam-Z instrument and characterize its radiometric and geometric behavior. Between April 26thth and May 9thth, 2019, ∼45,000 images were acquired during stand-alone calibration at Malin Space Science Systems (MSSS) in San Diego, CA. Additional data were acquired during Assembly Test and Launch Operations (ATLO) at the Jet Propulsion Laboratory and Kennedy Space Center. Results of the radiometric calibration validate a 5% absolute radiometric accuracy when using camera state parameters investigated during testing. When observing using camera state parameters not interrogated during calibration (e.g., non-canonical zoom positions), we conservatively estimate the absolute uncertainty to be 0.2 design requirement. We discuss lessons learned from calibration and suggest tactical strategies that will optimize the quality of science data acquired during operation at Mars. While most results matched expectations, some surprises were discovered, such as a strong wavelength and temperature dependence on the radiometric coefficients and a scene-dependent dynamic component to the zero-exposure bias frames. Calibration results and derived accuracies were validated using a Geoboard target consisting of well-characterized geologic samples
