Improving Quality of Life and Reducing Behavioral Problems of People With Intellectual and Developmental Disabilities Through Deinstitutionalization.

ANTECEDENTS: People with intellectual and developmental disability (IDD) with extensive support needs are more likely to live in segregated and highly institutionalized environments. The aim of this study was to analyze changes in functioning and quality of life for people with IDD and extensive support needs after transitioning to ordinary homes in the community. METHOD: The sample included 54 adults with IDD and extensive support needs, who were assessed at three time points: before transition, six months later, and one year after transition. The Resident Choice Scale, San Martin Quality of Life Scale, Active Support Participation Measure, and the Behavior Problem section of the Inventory for Client and Agency Planning were administered. Partial least squares-structural equation modeling (PLS-SEM) and t-tests for repeated measures were carried out. RESULTS: There were significant improvements in decision-making, participation and independence in daily activities and quality of life, as well as a reduction in the presence and intensity of behavioral problems. CONCLUSIONS: The benefits found in this study support transformation processes towards more inclusive services and professional practices that foster people's rights and feeling of belonging to the community.

Construction and Validation of a Scale to Assess Social Judgments Toward Sex Work from the Stereotype Content Model.

Sex workers (SW) are subject to social judgment and the associated attitudes, ranging from admiration to contempt. The presence of stereotypical attitudes toward SW is common and can be analyzed using the Stereotype Content Model (SCM), where the concepts of warmth and competence play a central role. The interweaving of both dimensions allows the identification of four emotions and corresponding political positions toward SW: admiration (non-interventionism), pity (abolitionism), contempt (prohibitionism), and fear (regulationism). From the SCM framework, this study offers the construction, validation and performance of a 25-item scale with a snowball sample of 1,543 participants residing in Spanish-speaking countries. The four-factor hypothesized model yielded adequate values. Internal consistency was sufficient on all factors, as was model-based reliability and convergent validity. The scale also showed measurement invariance between gender and age groups, suggesting that the measure is interpreted in a conceptually similar manner by respondents representing different genders or ages. Further analysis revealed that male participants scored significantly higher on admiration. Baby boomers showed less pity and contempt while Millennials showed more fear and less admiration. SW and those who know or work with SW showed less fear and pity and more admiration. The SCM and the process of developing social judgments offer us a way to understand the differences that underlie irreconcilable policy positions. Overcoming these differences requires mutual understanding from scientific frameworks instead of from ideological perspectives.

Q-Herilearn: Assessing heritage learning in digital environments. A mixed approach with factor and IRT models.

The assessment of heritage learning in digital environments lacks instruments that measure it with sufficient guarantees of accuracy, validity, and reliability. This study attempts to fill this gap by developing an instrument that has shown solid metric qualities. The process of design and calibration of a scale applied to 1,454 participants between 19 and 63 years of age is presented in this article. Exploratory factor analysis (Exploratory Structural Equation Modeling ESEM) and Item Response Theory models (Graded Response Model GRM) were used. Sufficient evidence of both reliability and validity based on content and internal structure was obtained. Invariance of scores as a function of gender and age of participants has also been demonstrated. The discrimination parameters of the items have been found to be high, and the test information curves have shown that the subscales measure with sufficient precision wide ranges of the respective latent variables. The instrument presents wide possibilities of application to various areas of Heritage Education (e.g., design of programs in HE, definition and planning of teaching objectives, evaluation of programs, etc., in virtual environments).

Detecting non-content-based response styles in survey data: An application of mixture factor analysis.

It is common for some participants in self-report surveys to be careless, inattentive, or lacking in effort. Data quality can be severely compromised by responses that are not based on item content (non-content-based [nCB] responses), leading to strong biases in the results of data analysis and misinterpretation of individual scores. In this study, we propose a specification of factor mixture analysis (FMA) to detect nCB responses. We investigated the usefulness and effectiveness of the FMA model in detecting nCB responses using both simulated data (Study 1) and real data (Study 2). In the first study, FMA showed reasonably robust sensitivity (.60 to .86) and excellent specificity (.96 to .99) on mixed-worded scales, suggesting that FMA had superior properties as a screening tool under different sample conditions. However, FMA performance was poor on scales composed of only positive items because of the difficulty in distinguishing acquiescent patterns from valid responses representing high levels of the trait. In Study 2 (real data), FMA detected a minority of cases (6.5%) with highly anomalous response patterns. Removing these cases resulted in a large increase in the fit of the unidimensional model and a substantial reduction in spurious multidimensionality.

Micronuclei and nuclear buds in amniotic tissue of rats treated with cyclophosphamide.

Fetal development can be altered by DNA damage caused by maternal exposure to chemical, physical, or biological agents during gestation. One method of assessing genotoxicity is to detect micronuclei (MNs) and/or nuclear abnormalities. This can be performed in vivo and requires only frequently dividing tissues, such as amniotic tissue (AT), which is in contact with the fetal environment and is composed of very thin layers of cells. This study evaluated the presence of MNs, nucleoplasmic bridges, and nuclear buds (NBs) in the fetal AT following maternal exposure to cyclophosphamide (CP) during pregnancy. Pregnant Wistar rats were divided into a negative control group and an experimental group that was orally administered CP (10 mg/kg). Daily blood smears were obtained from pregnant rats on days 14-19 of gestation. The rats were dissected, and fetal ATs were obtained on the 19th day of gestation. The MN and NB frequencies in AT cells were analyzed using a fluorescence microscope (100 ×). Micronucleated erythrocytes in the peripheral blood of the control rats were also assessed. Micronucleated polychromatic erythrocyte frequencies were significantly higher than those in the controls. Polychromatic erythrocyte frequencies were lower in CP-treated rats than in controls at 48-120 h. Fetuses in the CP-treated group also showed a significant increase in MNs and NBs in AT cells. In conclusion, AT could be used for analyzing MNs and NBs in rats following maternal exposure to a genotoxic agent and as a viable alternative for analyzing the integrity of fetal DNA during gestation.

Effective intravenous delivery of adenovirus armed with TNFα and IL-2 improves anti-PD-1 checkpoint blockade in non-small cell lung cancer.

Lung cancer remains among the most difficult-to-treat malignancies and is the leading cause of cancer-related deaths worldwide. The introduction of targeted therapies and checkpoint inhibitors has improved treatment outcomes; however, most patients with advanced-stage non-small cell lung cancer (NSCLC) eventually fail these therapies. Therefore, there is a major unmet clinical need for checkpoint refractory/resistant NSCLC. Here, we tested the combination of aPD-1 and adenovirus armed with TNFα and IL-2 (Ad5-CMV-mTNFα/mIL-2) in an immunocompetent murine NSCLC model. Moreover, although local delivery has been standard for virotherapy, treatment was administered intravenously to facilitate clinical translation and putative routine use. We showed that treatment of tumor-bearing animals with aPD-1 in combination with intravenously injected armed adenovirus significantly decreased cancer growth, even in the presence of neutralizing antibodies. We observed an increased frequency of cytotoxic tumor-infiltrating lymphocytes, including tumor-specific cells. Combination treatment led to a decreased percentage of immunosuppressive tumor-associated macrophages and an improvement in dendritic cell maturation. Moreover, we observed expansion of the tumor-specific memory T cell compartment in secondary lymphoid organs in the group that received aPD-1 with the virus. However, although the non-replicative Ad5-CMV-mTNFα/mIL-2 virus allows high transgene expression in the murine model, it does not fully reflect the clinical outcome in humans. Thus, we complemented our findings using NSCLC ex vivo models fully permissive for the TNFα and IL-2- armed oncolytic adenovirus TILT-123. Overall, our data demonstrate the ability of systemically administered adenovirus armed with TNFα and IL-2 to potentiate the anti-tumor efficacy of aPD-1 and warrant further investigation in clinical trials.

An oncolytic adenovirus coding for a variant interleukin 2 cytokine improves response to chemotherapy through enhancement of effector lymphocyte cytotoxicity, fibroblast compartment modulation and mitotic slippage.

Pancreatic ductal adenocarcinoma (PDAC) is a highly treatment-resistant cancer. Currently, the only curative treatment for PDAC is surgery, but most patients are diagnosed with metastatic disease and thus outside the scope of surgery. The majority of metastatic patients receive chemotherapy, but responses are limited. New therapeutics are thus urgently needed for PDAC. One major limitation in treating PDAC has been the highly immunosuppressive tumor microenvironment (TME) which inhibits anti-cancer immune responses. We have constructed an oncolytic adenovirus coding for a variant the interleukin 2 molecule, Ad5/3-E2F-d24-vIL2 (also known as TILT-452, and "vIL-2 virus"), with preferential binding to IL-2 receptors on the surface of effector lymphocytes over T regulatory cells (T regs). In the present study this virus was evaluated in combination with nab-paclitaxel and gemcitabine chemotherapy in Panc02 mouse model. Ad5/3-E2F-d24-vIL2 showed marked PDAC cell killing in vitro, alongside induction of mitotic slippage and immunogenic cell death in PDAC cell lines, when combined with chemotherapy. Increased survival was seen in vivo with 80% of animals surviving long term, when compared to chemotherapy alone. Moreover, combination therapy mediated enhanced tumor growth control, without observable toxicities in internal organs or external features. Survival and tumor control benefits were associated with activation of tumor infiltrating immune cells, downregulation of inhibitory signals, change in fibroblast populations in the tumors and changes in intratumoral cytokines, with increased chemokine amounts (CCL2, CCL3, CCL4) and anti-tumor cytokines (IFN-γ and TNFα). Furthermore, vIL-2 virus in combination with chemotherapy efficiently induced tumor protection upon rechallenge, that was extended to a previously non-encountered cancer cell line. In conclusion, Ad5/3-E2F-d24-vIL2 is a promising immunotherapy candidate when combined with nab-paclitaxel and gemcitabine.

The ephemeral nature of wording effects.

This article explores the analysis and interpretation of wording effects associated with using direct and reverse items in psychological assessment. Previous research using bifactor models has suggested a substantive nature of this effect. The present study uses mixture modeling to systematically examine an alternative hypothesis and surpass recognized limitations in the bifactor modeling approach. In preliminary supplemental Studies S1 and S2, we examined the presence of participants who exhibited wording effects and evaluated their impact on the dimensionality of Rosenberg's Self-Esteem and the Revised Life Orientation Test, confirming the ubiquity of wording effects in scales containing direct and reverse items. Then, after analyzing the data for both scales (n = 5,953), we found that, despite a significant association between wording factors (Study 1), a low proportion of participants simultaneously exhibited asymmetric responses in both scales (Study 2). Similarly, despite finding both longitudinal invariance and temporal stability of this effect in three waves (n = 3,712, Study 3), a small proportion of participants was identified with asymmetric responses over time (Study 4), reflected in lower transition parameters compared to the other patterns of profiles examined. In both cases, we illustrate how bifactor models capitalize on the responses of individuals who do not even exhibit wording effects, yielding spurious correlations suggesting a substantive nature of the wording effect. These findings support the notion of an ephemeral nature underlying wording effects. The discussion focuses on alternative hypotheses to understand these findings and emphasizes the utility of including reverse items in psychological assessment.

A community living experience: Views of people with intellectual disability with extensive support needs, families, and professionals.

BACKGROUND: Despite the benefits of community living for people with intellectual disabilities (ID) and extensive support needs, they remain highly institutionalized. AIMS: To qualitatively analyze the perceptions of people with ID, including those with extensive support needs, professionals, and family members six months after the implementation of 11 community homes for 47 people in different regions of Spain METHODS: Thematic analysis of 77 individual interviews conducted with 13 people with ID, 30 professionals and 34 family members was performed using Nvivo12. RESULTS: Seven themes were found: (1) "the room as I like it", (2) "sometimes I don't obey", (3) "here I do a bit of everything", (4) "lots of people love me here", (5) "all thanks to them, who have helped me" (6) "I miss my mom", and (7) "I'm happy here". IMPLICATIONS: Transitioning into the community has shown a clear positive change in emotional well-being, opportunities to participate in activities or exercise control over one's life. Nevertheless, certain restrictions were still present in people's lives, which significantly limit their right to independent living. While many of these restrictions may disappear, professional practices typical of a medical model can be recreated in services located in the community.

Development of a Syrian hamster anti-PD-L1 monoclonal antibody enables oncolytic adenoviral immunotherapy modelling in an immunocompetent virus replication permissive setting.

Introduction: Immune checkpoint inhibitors (ICIs) have revolutionized the treatment of cancer, but preclinical testing of hypotheses such as combination therapies has been complicated, in part due to species incompatibility issues. For example, one of few known permissive animal models for oncolytic adenoviruses is the Syrian hamster, for which an ICI, mainly an anti-PD-L1 monoclonal antibody (mAb) was not previously available. In this study, we developed an anti-Syrian hamster PD-L1 mAb to enable the evaluation of safety and efficacy, when combining anti-PD-L1 with an oncolytic adenovirus encoding tumour necrosis factor alpha (TNFα) and interleukin-2 (IL-2) (Ad5/3-E2F-D24-hTNFα-IRES-hIL-2 or TILT-123). Methods: Recombinant Syrian hamster PD-L1 was expressed and mice immunized for mAb formation using hybridoma technology. Clonal selection through binding and functional studies in vitro, in silico and in vivo identified anti-PD-L1 clone 11B12-1 as the primary mAb candidate for immunotherapy modelling. The oncolytic virus (OV) and ICI combination approach was then evaluated using 11B12-1 and TILT-123 in a Syrian hamster model of pancreatic ductal adenocarcinoma (PDAC). Results: Supernatants from hybridoma parent subclone 11B12B4 provided the highest positive PD-L1 signal, on Syrian hamster PBMCs and three cancer cell lines (HT100, HapT1 and HCPC1). In vitro co-cultures revealed superior immune modulated profiles of cell line matched HT100 tumour infiltrating lymphocytes when using subclones of 7G2, 11B12 and 12F1. Epitope binning and epitope prediction using AlphaFold2 and ColabFold revealed two distinct functional epitopes for clone 11B12-1 and 12F1-1. Treatment of Syrian hamsters bearing HapT1 tumours, with 11B12-1 induced significantly better (p<0.05) tumour growth control than isotype control by day 12. 12F1-1 did not induce significant tumour growth control. The combination of 11B12-1 with oncolytic adenovirus TILT-123 improved tumour growth control further, when compared to monotherapy (p<0.05) by day 26. Conclusions: Novel Syrian hamster anti-PD-L1 clone 11B12-1 induces tumour growth control in a hamster model of PDAC. Combining 11B12-1 with oncolytic adenovirus TILT-123 improves tumour growth control further and demonstrates good safety and toxicity profiles.

Intoxicación por metanol por consumo de bebidas alcohólicas adulteradas. Efectos en el sistema nervioso. Reporte de un caso / Methanol Poisoning by Consumption of Adulterated Alcoholic Beverages. Effects on the Nervous System. A Case Report

Resumen La intoxicación por metanol puede ocurrir de forma inadvertida por la ingesta de bebidas alcohólicas adulteradas. Se trata una entidad poco frecuente, sin embargo, se ha reportado un aumento en la incidencia durante la pandemia de COVID-19. La intoxicación con metanol representa una urgencia médica, ya que puede provocar daño severo en el sistema nervioso central y periférico, además de acidosis metabólica, daño renal agudo e incluso la muerte. En este artículo se presenta el caso de un paciente que cursó con intoxicación por metanol de manera inadvertida al consumir bebidas alcohólicas presumiblemente adulteradas. En el encéfalo se demostró necrosis hemorrágica de ambos núcleos putamen, además de cursar con neuritis óptica bilateral y polineuropatía periférica. Fue manejado con pulsos de esteroides intravenosos, con lo cual, mejoró significativamente su función visual, sensitiva y motora. En el presente caso no existieron complicaciones fatales y presentó una buena respuesta al tratamiento, sin embargo, el caso pone de relieve la necesidad de una mejor regulación en la producción y comercialización de bebidas alcohólicas en nuestro país, y, por otro lado, permite hacer a un llamado a los consumidores a tomar más precauciones en el consumo de bebidas alcohólicas de dudosa calidad o procedencia.

Abstract Methanol poisoning can occur unnoticed, by the ingestion of adulterated alcoholic beverages. In general, it is a rare entity, however, an increase in incidence has been reported during the SARS-CoV-2 pandemic. Methanol poisoning represents a medical emergency as it can cause severe damage to the central and peripheral nervous systems, as well as metabolic acidosis, acute kidney injury, and even death. This article presents the case of a patient who inadvertently developed methanol intoxication after consuming presumably adulterated alcoholic beverages. In the brain, hemorrhagic necrosis of both putamen nuclei was demonstrated, in addition to presenting with bilateral optic neuritis and peripheral polyneuropathy. He was managed with intravenous steroid pulses, which significantly improved his visual, sensory, and motor function. In the present case there were no fatal complications and presented a good response to treatment, however, the case highlights the need for better regulation in the production and marketing of alcoholic beverages in our country, and on the other hand, to invite consumers to take more precautions in the consumption of alcoholic beverages of dubious quality or origin.

Oncolytic adenovirus coding for bispecific T cell engager against human MUC-1 potentiates T cell response against solid tumors.

Immunotherapy with bispecific T cell engagers has shown efficacy in patients with hematologic malignancies and uveal melanoma. Antitumor effects of bispecific T cell engagers in most solid tumors are limited due to their short serum half-life and insufficient tumor concentration. We designed a novel serotype 5/3 oncolytic adenovirus encoding a human mucin1 antibody and the human CD3 receptor, Ad5/3-E2F-d24-aMUC1aCD3 (TILT-321). TILT-321 is engineered to replicate only in cancer cells, leading to a high concentration of the aMUC1aCD3 molecule in the tumor microenvironment. Infection and cell viability assays were performed to determine the oncolytic potential of the novel construct. The functionality of the virus-derived aMUC1aCD3 was evaluated in vitro. When TILT-321 was combined with allogeneic T cells, rapid tumor cell lysis was observed. TILT-321-infected cells secreted functional aMUC1aCD3, as shown by increased T cell activity and its binding to MUC1 and CD3. In vivo, TILT-321 treatment led to effective antitumor efficacy mediated by increased intratumoral T cell activity in an A549 and patient-derived ovarian cancer xenograft mouse model humanized with peripheral blood mononuclear cells (PBMC). This study provides a proof of concept for an effective strategy to overcome the key limitations of recombinant bispecific T cell engager delivery for solid tumor treatment.

Diagnosing molecular subtypes of breast cancer by means of Raman spectroscopy.

OBJECTIVES: Raman spectroscopy has been used to discriminate human breast cancer and its different tumor molecular subtypes (luminal A, luminal B, HER2, and triple-negative) from normal tissue in surgical specimens. MATERIALS AND METHODS: Breast cancer and normal tissue samples from 31 patients were obtained by surgical resection and submitted for histopathology. Before anatomopathological processing, the samples had been submitted to Raman spectroscopy (830 nm, 25 mW excitation laser parameters). In total, 424 Raman spectra were obtained. Principal component analysis (PCA) was used in an exploratory analysis to unveil the compositional differences between the tumors and normal tissues. Discriminant models were developed to distinguish the different cancer subtypes by means of partial least squares (PLS) regression. RESULTS: PCA vectors showed spectral features referred to the biochemical constitution of breast tissues, such as lipids, proteins, amino acids, and carotenoids, where lipids were decreased and proteins were increased in breast tumors. Despite the small spectral differences between the different subtypes of tumor and normal tissues, the discriminant model based on PLS was able to discriminate the spectra of the breast tumors from normal tissues with an accuracy of 97.3%, between luminal and nonluminal subtypes with an accuracy of 89.9%, between nontriple-negative and triple-negative with an accuracy of 94.7%, and each molecular subtype with an accuracy of 73.0%. CONCLUSION: PCA could reveal the compositional difference between tumors and normal tissues, and PLS could discriminate the Raman spectra of breast tissues regarding the molecular subtypes of cancer, being a useful tool for cancer diagnosis.

Local delivery of interleukin 7 with an oncolytic adenovirus activates tumor-infiltrating lymphocytes and causes tumor regression.

Cytokines have proven to be effective for cancer therapy, however whilst low-dose monotherapy with cytokines provides limited therapeutic benefit, high-dose treatment can lead to a number of adverse events. Interleukin 7 has shown promising results in clinical trials, but anti-cancer effect was limited, in part due to a low concentration of the cytokine within the tumor. We hypothesized that arming an oncolytic adenovirus with Interleukin 7, enabling high expression localized to the tumor microenvironment, would overcome systemic delivery issues and improve therapeutic efficacy. We evaluated the effects of Ad5/3-E2F-d24-hIL7 (TILT-517) on tumor growth, immune cell activation and cytokine profiles in the tumor microenvironment using three clinically relevant animal models and ex vivo tumor cultures. Our data showed that local treatment of tumor bearing animals with Ad5/3- E2F-d24-hIL7 significantly decreased cancer growth and increased frequency of tumor-infiltrating cells. Ad5/3-E2F-d24-hIL7 promoted notable upregulation of pro-inflammatory cytokines, and concomitant activation and migration of CD4+ and CD8 + T cells. Interleukin 7 expression within the tumor was positively correlated with increased number of cytotoxic CD4+ cells and IFNg-producing CD4+ and CD8+ cells. These findings offer an approach to overcome the current limitations of conventional IL7 therapy and could therefore be translated to the clinic.

Dominance of Three Sublineages of the SARS-CoV-2 Delta Variant in Mexico.

In this study, we analyzed the sequences of SARS-CoV-2 isolates of the Delta variant in Mexico, which has completely replaced other previously circulating variants in the country due to its transmission advantage. Among all the Delta sublineages that were detected, 81.5 % were classified as AY.20, AY.26, and AY.100. According to publicly available data, these only reached a world prevalence of less than 1%, suggesting a possible Mexican origin. The signature mutations of these sublineages are described herein, and phylogenetic analyses and haplotype networks are used to track their spread across the country. Other frequently detected sublineages include AY.3, AY.62, AY.103, and AY.113. Over time, the main sublineages showed different geographical distributions, with AY.20 predominant in Central Mexico, AY.26 in the North, and AY.100 in the Northwest and South/Southeast. This work describes the circulation, from May to November 2021, of the primary sublineages of the Delta variant associated with the third wave of the COVID-19 pandemic in Mexico and highlights the importance of SARS-CoV-2 genomic surveillance for the timely identification of emerging variants that may impact public health.

Psychotropic drugs intake in people aging with intellectual disability: Prevalence and predictors.

BACKGROUND: Psychotropic medication is frequently administered to people with intellectual disability with mental health and/or behavioural problems, instead of other non-pharmacological interventions. This study describes the mental health and behavioural problems of people aging with intellectual disability, their psychotropic medication intake, and the factors contributing to a greater medication intake. METHOD: The sample consisted of 991 people with intellectual disability over 45 years. Descriptive statistics and multinominal logistic regression were carried out. RESULTS: Antipsychotics were the most used psychotropic drug. Older people with mild intellectual disability living in institutions and affected by mental health and behavioural problems were more likely to take larger amounts of psychotropic medication. CONCLUSIONS: Antipsychotics continue to be widely used by people with intellectual disability and mental and behavioural health problems, especially those in institutionalised settings. Future research should consider if medication intake could be reduced providing better supports in the community and non-pharmacological interventions.

Aplicación internacional del programa “Intervención multidimensional para la ansiedad social” (IMAS): II. Eficacia del tratamiento para problemas relacionados con la ansiedad social / [International application of the program "Multidimensional intervention for social anxiety" (IMAS): II. Efficacy of treatment for problems related to social anxiety]

En un trabajo anterior (Caballo et al., 2021) comprobamos la eficacia del programa de Intervención multidimensional para la ansiedad social (IMAS) en la reducción de los síntomas de ansiedad social. En este estudio cuasiexperimental, con medidas pre/postratamiento y seguimiento, hallamos el impacto del programa IMAS en otros problemas relacionados con la ansiedad social. 57 personas diagnosticadas con un trastorno de ansiedad social (TAS), según el DSM-5, contestaron a cuestionarios que medían habilidades sociales, depresión, síntomas del trastorno de la personalidad por evitación, alcoholismo, autoestima, sensibilidad personal, preocupaciones y calidad de vida. Diferentes terapeutas llevaron a cabo el tratamiento en Ecuador, España y Paraguay. Los resultados mostraron importantes mejoras en el postratamiento en prácticamente todos los aspectos evaluados, mejoras que se mantenían a los seis meses. Los tamaños del efecto sobre la eficacia del tratamiento iban de medianos a grandes. Se comparó también el programa IMAS con terapia cognitivo conductual individual y tratamiento farmacológico, con resultados favorables para el programa IMAS. Este nuevo programa para el tratamiento de la ansiedad social tiene un impacto importante en otros problemas relacionados habitualmente con el TAS.

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.

Wording Effects in Assessment: Missing the Trees for the Forest.

This article examines wording effects when positive and negative worded items are included in psychological assessment. Wordings effects have been analyzed in the literature using statistical approaches based on population homogeneity assumptions (i.e. CFA, SEM), commonly adopting the bifactor model to separate trait variance and wording effects. This article presents an alternative approach by explicitly modeling population heterogeneity through a latent profile model, based on the idea that a subset of individuals exhibits wording effects. This kind of mixture model allows simultaneously to classify respondents, substantively characterize the differences in their response profiles, and report respondents' results in a comparable manner. Using the Rosenberg's self-esteem scale data from the LISS Panel (N = 6,762) in three studies, we identify a subgroup of participants who respond differentially according to item-wording and examine the impact of its responses in the estimation of the RSES measurement model, in terms of global and individual fit, under one-factor and bifactor models.The results of these analyses support the interpretation of wording effects in terms of a theoretically-proposed differential pattern of response to positively and negatively worded items, introducing a valuable tool for examining the artifactual or substantive interpretations of such wording effects.

Using Constrained Factor Mixture Analysis to Validate Mixed-Worded Psychological Scales: The Case of the Rosenberg Self-Esteem Scale in the Dominican Republic.

A common method to collect information in the behavioral and health sciences is the self-report. However, the validity of self-reports is frequently threatened by response biases, particularly those associated with inconsistent responses to positively and negatively worded items of the same dimension, known as wording effects. Modeling strategies based on confirmatory factor analysis have traditionally been used to account for this response bias, but they have recently become under scrutiny due to their incorrect assumption of population homogeneity, inability to recover uncontaminated person scores or preserve structural validities, and their inherent ambiguity. Recently, two constrained factor mixture analysis (FMA) models have been proposed by Arias et al. (2020) and Steinmann et al. (2021) that can be used to identify and screen inconsistent response profiles. While these methods have shown promise, tests of their performance have been limited and they have not been directly compared. Thus the objective of the current study was to assess and compare their performance with data from the Dominican Republic of the Rosenberg Self-Esteem Scale (N = 632). Additionally, as this scale had not yet been studied for this population, another objective was to show how using constrained FMAs could help in the validation of mixed-worded scales. The results indicated that removing the inconsistent respondents identified by both FMAs (≈8%) reduced the amount of wording effects in the database. However, whereas the Steinmann et al. method only cleaned the data partially, the Arias et al. (2020) method was able to remove the great majority of the wording effects variance. Based on the screened data with the Arias et al. method, we evaluated the psychometric properties of the RSES for the Dominican population, and the results indicated that the scores had good validity and reliability properties. Given these findings, we recommend that researchers incorporate constrained FMAs into their toolbox and consider using them to screen out inconsistent respondents to mixed-worded scales.
