RESUMEN

There are no assessment and screening tools for Autism Spectrum Disorders (ASD) validated for the Portuguese population. The Social Communication Questionnaire (SCQ) is an useful screening tool of ASD diagnosis. The main objectives of our study were to produce a Portuguese version of the SCQ (SCQ-PF), study its internal consistency, sensitivity and specificity in order to evaluate its validity as a screening instrument for ASD. We also wanted to study the impact of intellectual disability and verbal impairment and other mental disorders on SCQ-PF psychometric properties. The study included 211 children and adolescents, aged 4-17, divided in three groups: ASD Group (n = 96), Other Mental Disorders Group (OMD) (n = 63) and No Mental Disorders (NMD) Group (n = 52). Parents or other primary caregiver provided information on the SCQ items. The SCQ-PF score was significantly higher in the ASD group than in the other groups (p < 0.001). As to internal consistency, Cronbach's alpha was 87%. ASD subjects were distinguished from subjects without ASD (OMD and NMD Groups) and the area under the curve (AUC) was 0.897 (95% Confidence Interval: 0.852-0.943), for a cutoff of 14, which yielded the highest AUC, with values of sensitivity and specificity 0.76 and 0.93, respectively. These findings show that SCQ- PF with a cutoff of 14 is an acceptable and useful screening tool for ASD in the Portuguese population.

RESUMEN

Automatic lesion segmentation in mammography images assists in the diagnosis of breast cancer, which is the most common type of cancer especially among women. The robust segmentation of mammography images has been considered a backbreaking task due to: i) the low contrast of the lesion boundaries; ii) the extremely variable lesions' sizes and shapes; and iii) some extremely small lesions on the mammogram image. To overcome these drawbacks, Deep Learning methods have been implemented and have shown impressive results when applied to medical image segmentation. This work presents a benchmark for breast lesion segmentation in mammography images, where six state-of-the-art methods were evaluated on 1692 mammograms from a public dataset (CBIS-DDSM), and compared considering the following six metrics: i) Dice coefficient; ii) Jaccard index; iii) accuracy; iv) recall; v) specificity; and vi) precision. The base U-Net, UNETR, DynUNet, SegResNetVAE, RF-Net, MDA-Net architectures were trained with a combination of the cross-entropy and Dice loss functions. Although the networks presented Dice scores superior to 86%, two of them managed to distinguish themselves. In general, the results demonstrate the efficiency of the MDA-Net and DynUnet with Dice scores of 90.25% and 89.67%, and accuracy of 93.48% and 93.03%, respectively. Clinical Relevance--- The presented comparative study allowed to identify the current performance of deep learning strategies on the segmentation of breast lesions.

RESUMEN

The loss or death of a beloved pet creates a grief reaction comparable to that of the loss of a family member and may lead to the development of symptoms consistent with a diagnosis of persistent complicated grief disorder. Nevertheless, society does not always recognize it as a significant loss, which may contribute to bereaved owners feeling isolated and ashamed when coping with it, as well as not resorting to mental health professionals when necessary. The development of instruments to assess these reactions may contribute to improving the understanding of this suffering. This study aimed to adapt the Pet Bereavement Questionnaire for European Portuguese speakers. A non-probabilistic convenience sample of 169 adults who had a pet that died answered a battery of questionnaires, which included the Portuguese version of the Pet Bereavement Questionnaire. This version resulted from a consensus translation prepared by two translators and subsequently subjected to a cognitive debriefing. The Portuguese version of the instrument demonstrated good reliability (good internal consistency for the total questionnaire and for its subscales) and good external validity (negative correlation with well-being measures and positive correlation with psychopathology measures), as well as reasonable internal validity and sensitivity.

RESUMEN

BACKGROUND: Type 2 diabetes Mellitus is a chronic disease, and one of its complications may result in amputation. The goal of this study was to evaluate the impact of psychosocial variables, over time, on quality of life (QoL) of caregivers of patients (N = 110) who had undergone a recent amputation. METHOD: A longitudinal design was employed: (T1) 1 month after the patient's surgery; (T2) 7 months after; and (T3) 10 months after. Burden Assessment Scale, Family Assessment Device, Revised Impact of Events Scale, Family Disruption from Illness Scale, and Short Form Health Survey were used. A path analysis model was tested. RESULTS: Burden, perception of family functioning, and traumatic symptoms at T1 showed a positive impact on the perception of family functioning, at T2. Traumatic symptoms, at T1, predicted traumatic symptoms at T2 being also a mediator between those symptoms (T1) and physical QoL (T3). Physical and traumatic symptoms, at T1 predicted physical symptoms, at T2 affecting both mental and physical QoL (T3), being also a mediator in these relationships. Burden (T1) also had a direct effect on mental QoL (T3) and at T2 had an impact on physical QoL (T3) mediating also the relationship between burden/physical symptoms at T1 and physical QoL, at T3. CONCLUSION: Intervention should focus on physical and traumatic symptoms as well as burden since they were both mediators regarding mental and physical QoL.

RESUMEN

BACKGROUND: The 'funnel effect' of Fibromyalgia (FM) assumes that as patients access healthcare services, they present greater severity and a more complex clinical situation than individuals with FM from the general population, but the studies comparing patients treated in different levels of healthcare are scarce. The aim of this study was to analyse the 'funnel effect' hypothesis by comparing patients from secondary and tertiary healthcare services. METHODS: A cross-sectional sample of female patients was selected in secondary (rheumatology practices - RP) and in tertiary healthcare (chronic pain clinics - CPC). Information about sociodemographic, clinical and psychological characteristics was collected and health related quality of life (HRQL) was assessed. RESULTS: In total, 55 patients from RP and 60 patients from CPC were included in the comparison. Patients from CPC revealed a worst clinical status (higher number of tender points, medical visits and comorbidity), more somatic symptoms (pain and daytime dysfunction levels) and worst emotional status (more anxiety) than patients from RP. Patients attending CPC also revealed a worst HRQL than RP patients although this difference was mediated by the differences in clinical and psychological variables. CONCLUSIONS: Our study supports the 'funnel effect' hypothesis among patients of different healthcare levels, with patients from tertiary healthcare services revealing worst clinical status, more somatic and psychological symptoms, and worst HRQL than patients from secondary healthcare services. SIGNIFICANCE: The worst clinical and psychological status and poorer quality of life in the patients from tertiary healthcare (chronic pain clinics) in relation to the patients from secondary healthcare (rheumatology practices) must be taken into account to design studies that assess any of these aspects, to a proper analysis and interpretation of the data, and to define the scope of its generalization, as data from different clinical settings are not directly comparable.

RESUMEN

The Mental Health Continuum-Short Form (MHC-SF) is a self-report questionnaire that allows the assessment of positive mental health, including three well-being components-emotional, psychological and social-as well as the categorical diagnosis of the presence or absence of mental health. The purpose of this study is to describe the adaptation and validation of the Portuguese version of MHC-SF and to examine whether this is an adequate measure of positive mental health for the Portuguese context. The participants included 1448 respondents between the ages of 18 and 94 (M = 33.15; SD = 16.3), 70.1% of which were females. Results confirm the reliability (α = .93), tripartite factor structure, and the external and internal validity of the MHC-SF. Data also supported the two-continuum model, with positive mental health and mental illness belonging to two correlated but distinct dimensions. These findings indicated that the Portuguese MHC-SF is valid instrument to measure well-being and positive mental health.

RESUMEN

Objective: Lower limb amputation (LLA) leads to several emotional and physical sequelaes that have a negative impact on individuals` life. The objectives of this study were: 1) to analyze the relationship between emotional reactions (anxiety, depression and traumatic stress symptoms) and functionality level, before and after a LLA due to diabetic foot ulcer, and mental/physical quality of life; and 2) to analyze the mediator role of social support between emotional reactions and mental/physical quality of life. Method: A multicenter, longitudinal study with four time assessments: before the surgery, one month, six months, and ten months after surgery, including 206 individuals hospitalized with diabetic foot ulcer indicated for a LLA. The instruments used were the following: Revised Impact of Event Scale; Barthel Index; Hospital Anxiety and Depression Scale and SF-36. Results: Anxiety symptoms before surgery and depression symptoms one month after surgery contribute to Mental Component Score (MCS) ten months after surgery. The level of functionality before and one month after surgery, traumatic stress symptoms one month after surgery as well as satisfaction with social support six months after surgery contribute to the Physical Component Score (PCS), ten months after surgery. Social support was a mediator between traumatic stress symptoms one month after surgery and PCS ten months after surgery. Conclusion: Identifying risk variables and the extent to which and when they affect mental/physical quality of life, will help to develop appropriate psychological interventions to promote quality of life in this population.

RESUMEN

Objective: Human papilloma virus (HPV) is the world's most common causative agent in sexually transmitted viral infections; thus requiring clinical guidance, before and after treatment, to promote better quality of life in women diagnosed with HPV. The HPV Impact Profile (HIP) is a comprehensive instrument used to assess the psychosocial impact of HPV and related interventions in a wide range of domains. The main purpose of this study was to validate the HIP in Portuguese women, so that it can be used in this population, both in research and in clinical settings. Methods: A sample of 178 Portuguese women infected with HPV were assessed with the following instruments: Index of Sexual Satisfaction, Hospital Anxiety and Depression Scale and HPV Impact Profile. Results: The results of the confirmatory factor analysis showed some changes to the original model, which resulted in an adapted version with six domains, compared to the seven domains of the original model. The final model showed a good fit to the data. All Cronbach's alphas were higher than 0.79 indicating a high level of internal consistency of the subscales. As in the original HIP questionnaire, the exception was sexual impact, with a lower, but acceptable, Cronbach's alpha. Convergent and discriminant validities of the instrument were also assessed. Conclusions: The Portuguese version of the HIP presents good psychometric properties, allowing its use in clinical trials as well as in clinical practice in order to evaluate quality of life in women with HPV.

RESUMEN

PURPOSE: Multiple sclerosis (MS) is a long-lasting disabling disease with psychological implications. Hospital Anxiety and Depression Scale (HADS) is a questionnaire developed to screen anxiety and depression among patients in hospital settings. The objective of this report was to study the metric properties of the Portuguese version of HADS regarding MS. MATERIALS AND METHODS: This was a cross-sectional study. Three hundred and eighty individuals with a diagnosis of MS, according to the revised McDonald criteria, were recruited from an outpatient Neuroimmunology Clinic of the city of Porto. Participants had a mean age of 40.04 years (SD =10.86), 63.9% of them were female. HADS consists of two subscales - anxiety and depression - scored separately, with seven items each. RESULTS: The results of our study show the appropriateness of HADS for the identification of mood changes in people with MS and show good metric properties. CONCLUSION: It seems to be a useful tool for the scrutiny of mood disorders in Portuguese patients with MS. The questionnaire is also sensitive to disease when compared to people with other severe illnesses, and with people without the disease.

RESUMEN

OBJECTIVE: This longitudinal multisite study examined the influence of demographic characteristics, psychological reactions, functionality, coping strategies, and social support on psychosocial adjustment to lower limb amputation 10 months after surgery. METHOD: Of an initial referral of 206 Portuguese patients, a sample of 86 patients who underwent a lower limb amputation due to Diabetes Mellitus Type II were evaluated during the hospitalization that preceded surgery (t0) and at inpatient follow-up consultations, 1 (t1), 6 (t2), and 10 months (t3) after surgery. RESULTS: Higher levels of anxiety symptoms and functionality at presurgery were associated with lower social adjustment to amputation and with higher adjustment to the limitations (t3) respectively. Traumatic stress symptoms (t1) were negatively associated with general and social adjustment, and with the adjustment to the limitations (t3). Perceived social support (t2) mediated the relationship between traumatic stress symptoms (t1) and adjustment to the limitations (t3). Male gender was associated with a higher anxiety and depression symptoms (t0) and with a higher level of functionality (t1). Male gender was associated with functionality at presurgery and postsurgery, and with anxiety and depression symptoms of presurgery. IMPLICATIONS: Results support the need to improve psychological screening and early treatment of anxiety symptoms before the surgery, as well as depression and traumatic stress symptoms after a lower limb amputation, and the promotion of social support over time, in order to promote psychosocial adjustment to amputation. This set of psychosocial variables should be included when planning postamputation rehabilitation and psychosocial intervention programs for this target population. (PsycINFO Database Record

RESUMEN

In people with schizophrenia several factors are associated with poor quality of life (QoL), namely, lifestyle-related factors and psychological factors. However, there has been little research on the impact of these factors on QoL. Therefore, the relation between lifestyle-related factors, psychological factors, and QoL in people with schizophrenia was assessed. A cross-sectional study was conducted among 115 patients (25% women, 50% inpatients). QoL was measured by World Health Organisation Quality of Life- Brief Version. Lifestyle-related factors were assessed, namely physical activity (International Physical Activity Questionnaire- Short Form), sleep quality (Pittsburgh Sleep Quality Index) and dietary intake (Mediterranean Diet score). Psychological factors such as self-esteem (Rosenberg Self-Esteem Scale) and autonomous motivation (Behavioural Regulation Questionnaire- version 3) were also measured. Regression analyses were performed to identify significant predictors of QoL. Results showed that self-esteem predicted better global, physical, psychological and environmental QoL. Physical activity predicted better global and physical QoL, while sedentary time predicted poor social and environmental QoL. Identifying predictors of QoL has implication for the effective design and delivery of lifestyles interventions, including physical activity, dietary education and smoking cessation in people with schizophrenia. Adopting healthy lifestyles may lead to improved physical health, psychological well-being and QoL in this population.

RESUMEN

AIM: Being physically active is a complex behaviour in patients with schizophrenia. Several factors were identified as barriers to achieving active behaviours in this population. Therefore, the purpose of this study was to investigate among a number of barriers what predicts the most on physical activity (PA) in patients with schizophrenia. METHODS: A total of 114 patients (28♀) with schizophrenia were included. Body mass index (BMI) was calculated. Autonomous and controlled motivation (Behavioural Regulation in Exercise Questionnaire - 3), self-esteem (Rosenberg Self-esteem scale), quality of life (World Health Organization Quality of Life Scale - Brief version) and functional exercise capacity (6-minute walk test - 6MWT) were evaluated. Multiple Regression Analysis was applied to assess the effect of these variables on Total PA per week (International Physical Activity Questionnaire - short version). RESULTS: Autonomous motivation and domains of quality of life were positively correlated with Total PA per week. Stepwise multiple regression analyses showed that of all the candidate factors to predict PA, autonomous motivation and global domain of quality of life were found as significant predictors. CONCLUSION: Our findings help to understand the importance of autonomous motivation and quality of life for PA in patients with schizophrenia. Knowledge about these predictors may provide guidance to improve PA behaviour in this population.

RESUMEN

PURPOSE: People with schizophrenia have low physical activity levels that can be explained by the restriction in motivation. The Behavioural Regulation in Exercise Questionnaire-2 is a 19-item scale commonly used to assess five different motivational subtypes for physical activity. However, there are limited psychometric analyses of this version in the schizophrenia context. Moreover, there is a lack of information related to the psychometric properties of version 3 of this questionnaire, with 24 items and six different motivational subtypes. The aim of this study was to examine the construct validity of both Portuguese versions in people with schizophrenia. METHODS: A total of 118 persons with schizophrenia were included (30 women). Cronbach's alpha was used for internal consistency, Pearson's correlation for the retained motivation-types, confirmatory factor analysis for the structural validity of version 2 and exploratory factor analysis for the factor structure of version 3. RESULTS AND CONCLUSIONS: Analyses of version 2 provided an adequate fit index for the structure of the five factors. Exploratory analyses suggested retaining 2 factors of version 3. The results of this study suggest that version 3 was an appropriate measure to assess controlled and autonomous motivation for physical activity in people with schizophrenia and support its use in clinical practice and research. Implications for Rehabilitation This study supports the need to identify the reasons why people with schizophrenia practice physical activity. For that purpose, it is important to use valid and cost-effective instruments. The Portuguese version of BREQ-2 confirmed a 5-factor model and showed adequate fit for the application in people with schizophrenia. However, the incremental indices values were lower than expected. The Portuguese version of BREQ-3 showed acceptable psychometric properties to assess controlled and autonomous motivation for physical activity in people with schizophrenia.

RESUMEN

OBJECTIVE: optimism is an important variable that has consistently been shown to affect adjustment to quality of life in chronic diseases. This study aims to clarify if dispositional optimism exerts a moderating or a mediating influence on the personality traits-quality of life association, in Portuguese chronic patients. METHODS: multiple regression models were used to test the moderation and mediation effects of dispositional optimism in quality of life. A sample of 729 patients was recruited in Portugal's main hospitals and completed self-reported questionnaires assessing socio-demographic and clinical variables, personality, dispositional optimism, quality of life (QoL) and subjective well-being (SWB). RESULTS: the results of the regression models showed that dispositional optimism did not moderate the relationships between personality traits and quality of life. After controlling for gender, age, education level and severity of disease perception, the effects of personality traits on QoL and in SWB were mediated by dispositional optimism (partially and completely), except for the links between neuroticism/openness to experience and physical health. CONCLUSION: dispositional optimism is more likely to play a mediating, rather than a moderating role in personality traits-quality of life pathway in Portuguese chronic patients, suggesting that "the expectation that good things will happen" contributes to a better quality of life and subjective well-being.

Objetivo: o otimismo tem sido demonstrado como uma variável importante no ajustamento da qualidade de vida de pessoas com doenças crônicas. O estudo tem como objetivo verificar se o otimismo exerce um efeito moderador ou mediador entre os traços de personalidade e a qualidade de vida, em portugueses com doenças crônicas. Métodos: os modelos de regressão linear múltipla foram usados para avaliar o efeito de moderação e mediação do otimismo na qualidade de vida. A amostra, constituída por 729 doentes, recrutados nos principais hospitais de Portugal responderam a questionários de autorresposta avaliando questões sócio-demográficas e clínicas, personalidade, otimismo disposicional, qualidade de vida e bem-estar subjetivo. Resultados: os resultados encontrados mostraram que o otimismo disposicional não exerce um papel moderador entre os traços de personalidade e a qualidade de vida. Controlando por idade, sexo, nível de escolaridade e percepção da severidade da doença, o efeito dos traços de personalidade na qualidade de vida e no bem-estar subjetivo foi mediado pelo otimismo (parcial e total), expecto para as associações, neuroticismo/abertura à experiência e à saúde física. Conclusão: o otimismo disposicional exerce apenas um papel mediador entre os traços de personalidade e qualidade de vida, em pessoas com doenças crônicas, sugerindo que 'a expectativa de que coisas boas vão acontecer' contribui para uma melhor qualidade de vida e melhor bem-estar subjetivo. .

RESUMEN

Living with obesity is an experience that may affect multiple aspects of an individual's life. Obesity is considered a relevant public health problem in modern societies. To determine the comparative efficacy of different treatments and to assess their impact on patients' everyday life, it is important to identify factors that are relevant to the quality of life of obese patients. The present study aims to evaluate, in Portuguese obese patients, the simultaneous impact of several psychosocial factors on quality of life. This study also explores the mediating role of stigma in the relationship between positive/negative affect and quality of life. A sample of 215 obese patients selected from the main hospitals in Portugal completed self-report questionnaires to assess sociodemographic, clinical, psychosocial, and quality of life variables. Data were analysed using structural equation modeling. The model fitted the data reasonably well, CFI = 0.9, RMSEA = 0.06. More enthusiastic and more active patients had a better quality of life. Those who reflect lower perception of stigma had a better physical and mental health. Partial mediation effects of stigma between positive affect and mental health and between negative affect and physical health were found. The stigma is pervasive and causes consequences for psychological and physical health.

RESUMEN

BACKGROUND: Chronic illnesses are diseases of long duration and generally of slow progression. They cause significant quality of life impairment. The aim of this study was to analyse psychosocial predictors of quality of life and of subjective well-being in chronic Portuguese patients. METHODS: Chronic disease patients (n = 774) were recruited from central Portuguese Hospitals. Participants completed self-reported questionnaires assessing socio-demographic, clinical, psychosocial and outcome variables: quality of life (HRQL) and subjective well-being (SWB). MANCOVA analyses were used to test psychosocial factors as determinants of HRQL and SWB. RESULTS: After controlling for socio-demographic and clinical variables, results showed that dispositional optimism, positive affect, spirituality, social support and treatment adherence are significant predictors of HRQL and SWB. Similar predictors of quality of life, such as positive affect, treatment adherence and spirituality, were found for subgroups of disease classified by medical condition. CONCLUSIONS: The work identifies psychosocial factors associated with quality of life. The predictors for the entire group of different chronic diseases are similar to the ones found in different chronic disease subgroups: positive affect, social support, treatment adherence and spirituality. Patients with more positive affect, additional social support, an adequate treatment adherence and a feel-good spirituality, felt better with the disease conditions and consequently had a better quality of life. This study contributes to understanding and improving the processes associated with quality of life, which is relevant for health care providers and chronic diseases support.

RESUMEN

BACKGROUND: Mood disorders, namely depression and anxiety, have been well documented in patients with Multiple Sclerosis (MS). However, the putative associations between clinical features and mood disorders have not been well established. OBJECTIVES: To detect anxiety and depression in MS patients; and to investigate possible associations with clinical factors. SUBJECTS AND METHODS: 325 consecutive patients with MS and 183 healthy subjects answered the Hospital Anxiety and Depression Scale (HADS), a self-rating questionnaire. Multiple Regression Analysis and Multivariate Analysis of Covariance were applied to assess the effect of demographic and clinical factors on HADS' anxiety and depression scores, using age and disease duration as covariates. Logistic Regression Analysis was used to study the influence of these factors on anxiety and depression, as defined by two different cut-off scores (i.e., 8 and 11). RESULTS: Levels of anxiety and depression were significantly higher (p<0.001) for MS patients group than healthy subjects. Age, disease duration, age at onset, Kurtzke Expanded Disability Status Scale, and Multiple Sclerosis Severity Scale were positively associated with depression scores. Low education (i.e., <9 years) in MS was significantly associated with more anxiety and depression symptoms. CONCLUSIONS: The study findings support a close linkage between depressive mood and physical manifestations of MS.
