Psychosocial factors associated with treatment preference in mental health.

BACKGROUND: Studies examining the effects of incorporating patients' preferences into treatment outcomes highlight their impact on crucial aspects such as reduced dropout rates and enhanced effectiveness. Recognizing individuals' rights to participate in decisions about their treatments underscores the importance of studying treatment preferences and the factors influencing these choices. AIM: This study aims to identify treatment preferences (psychological, pharmacological, or combined) among a sample of patients and to discern the psychosocial and clinical factors influencing these preferences. METHODS: A total of 2,133 individuals receiving care at a community mental health unit completed assessments on anxious-depressive symptoms, social and occupational adjustment, and their treatment preference. Data analysis was conducted using SPSS, with descriptive statistics, Chi-square tests, and one-way ANOVA applied. RESULTS: Preferences for treatments were distributed as follows: Combined (49.8%), psychological (33%), and pharmacological (10.6%). Factors such as diagnosis, severity of depressive and anxious symptoms, and functional impact were related to treatment preference with a moderate effect size. Meanwhile, various sociodemographic factors correlated with the selected treatment, though with a weak effect size. CONCLUSIONS: There is a pronounced preference for combined treatments. The significance of psychological treatments is evident, as four out of five participants favored them in their choices. Addressing these preferences calls for an exploration within the broader context of prescription freedom in mental health.

Systemic neurophysiological signals of auditory predictive coding.

Predictive coding framework posits that our brain continuously monitors changes in the environment and updates its predictive models, minimizing prediction errors to efficiently adapt to environmental demands. However, the underlying neurophysiological mechanisms of these predictive phenomena remain unclear. The present study aimed to explore the systemic neurophysiological correlates of predictive coding processes during passive and active auditory processing. Electroencephalography (EEG), functional near-infrared spectroscopy (fNIRS), and autonomic nervous system (ANS) measures were analyzed using an auditory pattern-based novelty oddball paradigm. A sample of 32 healthy subjects was recruited. The results showed shared slow evoked potentials between passive and active conditions that could be interpreted as automatic predictive processes of anticipation and updating, independent of conscious attentional effort. A dissociated topography of the cortical hemodynamic activity and distinctive evoked potentials upon auditory pattern violation were also found between both conditions, whereas only conscious perception leading to imperative responses was accompanied by phasic ANS responses. These results suggest a systemic-level hierarchical reallocation of predictive coding neural resources as a function of contextual demands in the face of sensory stimulation. Principal component analysis permitted to associate the variability of some of the recorded signals.

Sources of social support and clinical and functional evolution of people with schizophrenia.

PURPOSE: The impact of social support on comprehensive measures of results (clinical and functional) of the course of schizophrenia was studied, understood and evaluated as a multidimensional construct differentiating sources of support (family vs. nonfamily). METHODS: One hundred fifty-two patients diagnosed with schizophrenia were assessed with the Mannheim Interview on Social Support (MISS) and the Social Functioning Scale (SFS). The hypotheses were explored in a prospective longitudinal design, using a causal correlational analysis for their evaluation by applying structural equation models. RESULTS: The only explanatory factor of social functioning was Nonfamily social support, while the only explanatory factor of clinical result measurements was Family social support, observing a clearly differentiated impact of the different sources of support on the schizophrenia result measurements. It was also found that while Family social support explained 6.8% of the variance in the clinical result measurements, Nonfamily social support explained 13.7% of the variance in social functioning. CONCLUSION: The results confirmed the differential importance of social support variables (family vs. nonfamily) in the clinical and functional result measurements of people with schizophrenia.

Survival of patients with severe mental disorders: Influence of social functioning.

BACKGROUND: Patients with severe mental disorders have a high risk of premature death due to the interaction of various factors. Social functioning is a strategic functional factor in understanding the course of psychotic disorders. AIM: Analyze the relationship between social functioning and its various dimensions and survival during a 10-year follow-up. METHOD: The Social Functioning Scale (SFS) was administered to 163 close relatives of patients under treatment at a Community Mental Health Unit. Survival was described by Kaplan-Meier analysis and any differences in survival by level of social functioning were found by long-rank analysis. Finally, Cox regression was used to predict premature mortality. RESULTS: Significant differences in mortality were identified in the interpersonal behavior dimension of social functioning, while there were no significant gender or diagnostic differences in the rest of the dimensions. The interpersonal behavior dimension and age were found to be factors predicting premature death. CONCLUSION: These findings show the protective effect of social functioning retained by patients with psychotic disorders on their survival, and the need to apply evidence-based psychotherapy focused on recovery of social functioning in the early stages of the disorder.

Personal Beliefs about Illness Questionnaire-Revised (PBIQ-R): Spanish adaptation in a clinical sample with psychotic disorders.

BACKGROUND: The way people with psychosis psychologically adapt and manage the diagnosis of such a mental disorder has been considered a key factor that contributes to the emergence and aggravation of emotional problems. These beliefs about illness can be very important due to their possible association with stigma and its implications in terms of loss of roles and social status. Given the importance of these personal beliefs about the specific diagnosis of psychosis, the Personal Beliefs about Illness Questionnaire (PBIQ) and PBIQ-R have been developed. AIMS: The present study aims to explore the psychometric characteristics of the Spanish version of the PBIQ-R in a sample of patients with a diagnosis of psychosis-related disorders. METHOD: Participants were 155 patients (54.8% male) of the Public Health Service in Andalusia (Spain). Those who consented to participate filled in the PBIQ-R, the Social Comparison Scale, and the PHQ-9 and GAD-7 to measure emotional symptoms. RESULTS: All dimensions showed adequate internal consistency values: Cronbach's alpha extends between .81 and .88; and McDonald's omega ranges between .87 and .92. The temporal reliability for an interval of 3-4 weeks was high. The correlations between the PBIQ-R dimensions and the other variables included in the study were significant and in the expected direction. The factor analysis of the principal components of the PBIQ-R dimensions revealed a single factor in each of the dimensions that explained 64-74%. CONCLUSIONS: The results support the reliability and validity of the Spanish version of the PBIQ-R.

Ten-year follow-up of social functioning and behaviour problems in people with schizophrenia and related disorders.

BACKGROUND: In recent years, several variables in the course of schizophrenia and related psychotic disorders have been studied. However, an instrumental analysis of the evolution of social functioning and behaviour problems has scarcely been explored. AIM: To analyse the evolution of social functioning and behaviour problems and find any diagnosis or gender differences. METHOD: The Social Functioning Scale (SFS) and the Behaviour Problems Inventory (BPI) were administered in Stages I (2003-2007) and II (2014-2017) to 100 close relatives of patients under treatment at a Community Mental Health Unit. A related samples t-test, analysis of variance and multivariate analysis of variance were performed to study the evolution and differences in social functioning and behaviour problems. Then a stepwise multiple linear regression analysis was done to predict the evolution of social functioning. RESULTS: No deterioration in the evolution of social functioning or behaviour problems was observed, and schizophrenia patient scores were lower. Women scored higher in withdrawal/social engagement, interpersonal behaviour, independence-performance, independence-competence and total social functioning, with no significant differences in behaviour problems. Previous social functioning, underactivity/social withdrawal and education are predictive factors in the evolution of social functioning. Conclusion: The results show the need for implementing psychosocial intervention programs that promote functional recovery and keep problems from becoming chronic.

Description of characteristics and outcomes of a cohort of patients with severe and enduring eating disorders (SE-ED).

OBJECTIVE: To describe the characteristics of the patients, as well as the treatment outcomes for the people treated in an Endocrinology and Nutrition unit with a diagnosis of SE-ED (> 7 years evolution despite evidence-based conventional treatment). METHODS: A descriptive observational study was conducted. Patients with a diagnosis of SE-ED (anorexia nervosa and bulimia nervosa) treated in the Endocrinology and Nutrition service of the Virgen del Rocío University Hospital between 2014 and 2019 were included. RESULTS: 67 patients were contacted and accepted to participate in the study. 95.5% were women. 67.2% were diagnosed with AN (anorexia nervosa) and 32.8% with BN (bulimia nervosa). Their median ages (years) at the onset of symptoms, beginning of follow-up and at present were 17, 32 and 42.5 respectively. Their median time of follow-up was 9 years. 73.1% had mental comorbitidy and AN patients had more osteoporosis (48.9% vs 22.7%, p = 0.04) and hypogonadotropic hypogonadism (31.1% vs. 4.5%, p = 0.014). DISCUSSION: The SE-ED patients in our sample began treatment years after the onset of symptoms, which may have led to their chronification. This emphasizes the importance of an early diagnosis in eating disorders. They presented with a high rate of physical complications and mental comorbidity. In the current sample, it was determined that patients with AN presented with higher rates of osteoporosis and hypogonadotropic hypogonadism than patients with BN. LEVEL OF EVIDENCE: Level III: Evidence obtained from well-designed cohort or case-control analytic studies. At present, the criteria for severe and enduring eating disorders (SE-ED) are not sufficiently clearly defined. It has been calculated that approximately 20% of patients with anorexia nervosa (AN) and 10% of patients with bulimia nervosa (BN) suffer a chronification. We evaluated the characteristics of the patients, as well as the treatment outcomes for the people treated in an Endocrinology and Nutrition unit with a diagnosis of SE-ED (which was made based on an evolution greater than 7 years despite conventional treatment). The SE-ED patients in our sample began treatment years after the onset of symptoms, which may have led to their chronification. They presented with a high rate of physical complications and mental comorbidity. In the current sample, it was determined that patients with AN presented with higher rates of osteoporosis (health condition that weakens bones, making them fragile and more likely to break) and hypogonadotropic hypogonadism (illness in which testes or ovaries produce little or no sex hormones due to a problem in the pituitary gland) than patients with BN.

Work and Social Adjustment Scale (WSAS): psychometric characteristics of a Spanish adaptation in a clinical population.

BACKGROUND: The Work and Social Adjustment Scale (WSAS) is an instrument that can be easily applied for routine evaluation of the impact of mental disorders on patient functioning. In spite of the interest in its use, there is very little information available on its psychometric characteristics and even less in Spanish. AIMS: The objective of this study was to analyse its psychometric characteristics. METHOD: The sample consisted of 441 patients treated in a community mental health unit. They filled out the WSAS and two psychopathology measures, one for anxiety and the other for depression. Fifty-five of them, chosen at random, were asked to fill out the scale again a second time to explore its temporal reliability. RESULTS: The scale showed high internal consistency, a single factor that explained 60.4% of the variance, and temporal reliability of .78 for the total score. Significant correlations were found between the WSAS scores and the psychopathological measures, as well as significant differences between those working and those on leave. CONCLUSIONS: The results confirm the validity and reliability of the scale and support its possible use for routine evaluation of the functional impact of mental disorders.

Spanish Validation of the Recovery Assessment Scale (RAS-24).

BACKGROUND: Recovery is an essential construct in healthcare treatment for patients diagnosed with severe mental illnesses (SMI). Of all the psychometric instruments available for measuring recovery, the 41-item Recovery Assessment Scale (RAS) is the most widely used. Several brief versions have been proposed, including the 24-item version. In this study, the RAS-24 was adapted to European Spanish and validated in a clinical sample. METHOD: Participants ( N = 309) diagnosed with SMI were recruited from a community mental health center and a work guidance center. The participants completed the RAS-24 and the Social Functioning Scale (SFS), both self-reported and family-reported versions. RESULTS: The results showed good indices of fit for the original five-factor structure, acceptable internal consistency (α = .93; ω = .95), temporal reliability ( ICC = .89, p <.01), and significant correlation with most of the SFS scales (total SFS self-report r = .50, p <.01; total SFS family reported r =.49, p <.01). CONCLUSIONS: These data support the use of this Spanish version as a measure of recovery in the Spanish clinical population.

Gender influence on severe mental disorders: relationship between behavior problems and family burden / Influencia del género en trastornos mentales graves: relación entre problemas de comportamiento y carga familiar

Gender differences in behavior problems and their relationship with family burden in severe mental disorders were analyzed. The Behavior Problems Inventory (BPI) and two items related to family burden (FB 1: "Do you feel able to endure the illness or disorder and the problems it causes?" and FB 2: "How often are you overwhelmed by these behavior/illness problems?") were administered to 235 key informants under treatment in a community mental health unit. The results show that men presented more behavior problems and family burden, with significant differences in impulse dyscontrol and severe behavior problems. A positive correlation was found between behavior problems and family burden, where the inactivity/social withdrawal dimension was the best predictor of family load for men and women. We conclude that men have more behavior problems and that the inactivity/social withdrawal dimension has the most explanatory power for family burden in both men and women. (AU)

Se analizan las diferencias de género en problemas de conducta y su relación con la carga familiar en trastornos mentales graves. El Inventario de Problemas de Conducta (BPI) y dos ítems relativos a la carga familiar ("¿Se siente usted capaz de sobrellevar la enfermedad o trastorno y los problemas que ocasiona?" y "¿Con qué frecuencia se ve usted desbordado/a por estos problemas de comportamiento/enfermedad?") se administraron a 235 informantes clave de pacientes en tratamiento en una unidad de Salud Mental Comunitaria. Los hombres presentaban mayores problemas de conducta y carga familiar, existiendo diferencias significativas en descontrol de impulsos y en problemas de comportamiento graves. Se halla una correlación positiva entre problemas de comportamiento y carga familiar, siendo la dimensión inactividad/aislamiento social la mejor predictora de carga familiar. Respecto a la carga familiar, es la dimensión inactividad/aislamiento social la que posee mayor capacidad explicativa en hombres y mujeres. (AU)

Anxious Thoughts Inventory (AnTI). Psychometric characteristics of an adaptation to the Spanish clinical population / Inventario de Pensamientos Ansiosos (AnTI). Características psicométricas de una adaptación en población clínica española

OBJECTIVE: This study shows the psychometric characteristics and factor structure of the Spanish adaptation to a clinical population of an instrument for measuring anxious worry, the Anxious Thought Inventory (AnTI). METHOD: Participants were 731 adults treated at a community mental Health Center in Spain with different clinical diagnoses. RESULTS: The adaptation of the AnTI scale to the Spanish clinical population confirms the three original dimensions, social worry, health worry and meta-worry, with adequate fit. High internal consistency (from .83 to .86) was found for the three subscales, and test-retest reliability after a period of 8-10 weeks was high (r = .71). Furthermore, significant correlations were found with other worry, anxiety and general psychopathology scales. CONCLUSIONS: This Spanish adaptation of the AnTI in a clinical population is a reliable, valid measure of anxious worry. Therefore, it is a useful instrument for use in care contexts

OBJETIVO: El presente estudio muestra las características psicométricas y estructura factorial de la adaptación española en población clínica de un instrumento de medida de las preocupaciones ansiosas: el Anxious Thought Inventory (AnTI). MÉTODO: Los participantes fueron 731 adultos tratados en un centro de salud mental comunitario español, con diferentes diagnósticos clínicos. RESULTADOS: Se confirman las tres dimensiones originales, preocupación social, preocupación por la salud y meta-preocupación con un adecuado ajuste. Se obtuvo una alta consistencia interna (.83-.86) para las tres subescalas, y la fiabilidad test-retest tras un período de 8-10 semanas fue alta (r = .71). Por otra parte, se obtuvieron correlaciones significativas con otras medidas de preocupación, de ansiedad, así como de psicopatología general. CONCLUSIONES: La presente adaptación española del AnTI en población clínica es una medida fiable y válida de las preocupaciones ansiosas. Por ello se trata de un instrumento de utilidad para su uso en distintos contextos asistenciales

Validation of a spanish version of the brief experiential avoidance questionnaire (beaq) in clinical population / Validación de la versión española del Cuestionario Breve de Evitación Experiencial (BEAQ) en población clínica

Background: The Brief Experiential Avoidance Questionnaire (BEAQ) has been suggested as the most appropriate instrument for measuring experiential avoidance. However, no Spanish validation has been published. The aim of this study was to validate a Spanish version of the BEAQ in a clinical sample treated at a community mental health unit. Methods: Participants (N = 332) completed the BEAQ as well as other self-report measures of experiential avoidance and psychopathology. Results: Internal consistency was satisfactory (α = .82). No statistically significant gender differences were found in the BEAQ scores. The data also showed high test-retest reliability after four to six weeks, acceptable concurrent validity with another experiential avoidance measure and acceptable convergent validity with the psychopathology measure. The principal component analysis, forcing the one factor solution proposed in the original scale, produced indicators similar to the English version of the BEAQ. Conclusions: These results firmly support the reliability and validity of this Spanish validation, stressing its usefulness as a measure of experiential avoidance in clinical populations

Antecedentes: el Cuestionario Breve de Evitación Experiencial (BEAQ) ha sido propuesto como el instrumento más adecuado para medir la evitación experiencial. Sin embargo, todavía no ha sido publicada ninguna validación en español. Por lo tanto, el objetivo del presente estudio ha sido la validación de una versión española del BEAQ, en una muestra clínica atendida en un Centro de Salud Mental Comunitario. Método: los participantes (N = 332) completaron el BEAQ, así como otras medidas de autoinforme de evitación experiencial y psicopatología. Resultados: la consistencia interna fue satisfactoria (α = .82). No se encontraron diferencias de género estadísticamente significativas en las puntuaciones del BEAQ. Los datos también mostraron una alta fiabilidad test-retest en un intervalo de cuatro a seis semanas, validez concurrente aceptable con otra medida de evitación experiencial y validez convergente aceptable con la medida de psicopatología. El análisis de componentes principales forzando a la solución de un factor, como se propuso en la escala original, obtuvo unos indicadores similares a los obtenidos en dicha versión inglesa. Conclusiones: los resultados confirman la adecuada fiabilidad y validez de la presente versión española del BEAQ, destacando su utilidad como medida de la evitación experiencial en población clínica

Social support and clinical and functional outcome in people with schizophrenia.

PURPOSE: The impact of Social Support (SS) on the clinical and functional evolution of patients diagnosed with schizophrenia was studied from a multidimensional concept of SS in the framework of the vulnerability-stress model. METHODS: In total, 152 patients diagnosed with schizophrenia according to the International Classification of Diseases, Tenth Edition (ICD-10) treated in a Community Mental Health Unit were assessed using the Mannheim Interview on Social Support (MISS) and the Brief Psychiatric Rating Scale (BPRS). Then they were followed up for 3 years with a final assessment for the period using the Social Functioning Scale. The impact of SS was explored in clinical and functional measurements with a multiple regression analysis in a 3-year longitudinal prospective design. RESULTS: The quality of Global Social Support (GSS) and satisfaction with GSS appeared to be protective factors from frequency and duration of hospital admissions, with explanatory intensity varying from 9% in survival time to relapse to 13% in number of relapses. Concerning functional measurements, GSS quantity, quality and satisfaction showed an explanatory power for several different dimensions of social functioning, varying from 12% in isolation to 20% in communication. CONCLUSION: The results confirm SS as a protective factor in the evolution of schizophrenia patients and enable the SS variables with the most explanatory power in their clinical and functional evolution to be identified.

Behavior Problems Inventory (BPI): Psychometric characteristics of an instrument for routine assessment of persons with psychoses and related disorders.

This study explores the psychometric characteristics of the Behavior Problems Inventory (BPI), an instrument for routine clinical assessment of behavior problems in outpatients with psychosis based on information provided by key family informants. Six hundred and twenty-one patients diagnosed with psychosis and bipolar affective disorder (ICD-10 F20-F31) attended at Community Mental Health Units were evaluated in routine reviews using the BPI and the Social Functioning Scale (SFS). Twenty-five subjects were simultaneously administered the Social Behavior Schedule (SBS) and 28 were again administered the BPI eight weeks later. The instrument shows adequate psychometric characteristics with high internal consistency and robust temporal reliability, as well as satisfactory concurrent and construct validity. Factor analysis identified three factors: Underactivity/Social Withdrawal, Active Problems and Lack of Impulse Control, with adequate saturation of the items on each of the factors. The BPI is easy to apply, reliable and valid, takes up little of valuable clinical time, allowing routine assessment in public service contexts for persons diagnosed with psychosis and bipolar affective disorder for whom key family informants are available.

Predictors in use of mental health resources: The role of behaviour problems in patients with severe mental illness.

BACKGROUND: In recent years, more variables are being included in the use of mental health resource prediction models. Some studies have shown that how well the patient can function is important for this prediction. However, the relevance of a variable as important as behaviour problems has scarcely been explored. AIM: This study attempted to evaluate the effect of behaviour problems in patients with severe mental illness on the use of mental health resources. METHOD: A total of 185 patients at a Community Mental Health Unit were evaluated using the Behaviour Problem Inventory. Later, a bivariate logistic regression was done to identify what behaviour problems could be specific predictors of use of mental health resources. RESULTS: The results showed that the general index of behaviour problems predicts both use of hospitalization resources and outpatient attention. Underactivity/social withdrawal is the best predictor of all the different areas. CONCLUSION: These results confirm the role of behaviour problems as predictors of the use of mental health resources in individuals with a severe mental illness.

Relationship between behavioural problems and use of mental health services in patients with severe mental illness and the mediating role of the perceived burden of care.

Mental health models proposed for predicting more use of mental health resources by patients with severe mental illness are including a wider variety of predictor variables, but there are still many more remaining to be explored for a complete model. The purpose of this study was to enquire into the relationship between two variables, behaviour problems and burden of care, and the use of mental health resources in patients with severe mental illness. Our hypothesis was that perceived burden of care mediates between behaviour problems of patients with serious mental illness and the use of mental health resources. The Behaviour Problem Inventory, which was filled out by the main caregiver, was used to evaluate 179 patients cared for in a community mental health unit. They also answered a questionnaire on perceived family burden. A structural equation analysis was done to test our hypothesis. The results showed that both the behaviour problems and perceived burden of care are good predictors of the use of mental health resources, where perceived burden of care mediates between behaviour problems and use of resources. These variables seem to be relevant for inclusion in complete models for predicting use of mental health resources.

Social functioning as a predictor of the use of mental health resources in patients with severe mental disorder.

Previous studies have tried to determine the factors causing greater use of health resources by patients with mental disorders. These studies have essentially focused on socio-economic variables. Nevertheless, many other variables, such as social functioning, have not yet been explored. This study aims to assess the effect of social functioning on mental health service use in a sample of patients with severe mental disorder (schizophrenia, other psychotic disorders or bipolar affective disorder) in an area of Spain. The Social Functioning Scale (SFS) was administered to 172 family members of patients with a severe mental disorder who were receiving care at a community mental health unit. Analysis of bivariate logistic regression identified specific areas as predictors of the use of mental health resources over a 12-month follow-up period. The overall social functioning score predicted need for hospital admissions. In addition, interpersonal behaviour had a major role in the number of outpatient visits, while social isolation significantly predicted the need for hospitalization. These results point out the necessity for including psychosocial variables, such as social functioning in current mental health resource use models.

Beck anxiety inventory: psychometric characteristics in a sample from the clinical Spanish population

Even though the Beck Anxiety Inventory (BAI) is one of the most popular instruments to assess anxiety today, only limited data is available about its psychometric characteristics and normative values in clinical Spanish populations. A study was conducted to test the psychometric characteristics of a Spanish adaptation of the Beck Anxiety Inventory (BAI) in a sample of 918 outpatients being treated at a community mental health center in Spain. Results confirmed the adaptation’s high internal consistency (∝ = .91), substantial test-retest reliability at 8-10 weeks (r = .84, p < .01), and satisfactory convergent validity with the Anxiety (r = .86, p < .01), Somatization (r = .81, p < .01), Obsessive compulsive (r = .60, p < .01), and Phobic Anxiety (r = .63, p < .01) dimensions of the SCL-90-R, and with the Anxious Thoughts Inventory (r = .57, p < .01). Gender differences in BAI scores did occur, so normative values appear separately for each gender (AU)
