RESUMEN
Objetivo: La soledad se asocia a la discapacidad funcional en la población mayor, aunque se sabe poco sobre el papel de la afectividad en esta relación. Nos proponemos explorar el efecto mediador de la afectividad en la relación entre funcionalidad y soledad, controlando el efecto de las variables relevantes. Métodos: Se administró la Escala de Soledad de la Universidad de California-16, la Escala de Funcionalidad Geriátrica, las Escalas de Afecto Positivo y Negativo-14 y la Escala de Depresión Geriátrica-8 a 489 adultos mayores (65100 años), 428 de residencias geriátricas y 61 de la comunidad. Resultados: Los residentes en una institución, mujeres, viudos, con baja educación, más discapacidad funcional, más afecto negativo, menos afecto positivo y más síntomas depresivos reportaron más soledad. Controlando el efecto de los síntomas depresivos, género, situación residencial, estado civil y educación, solo el afecto positivo medió, parcialmente, la relación entre funcionalidad y soledad. Conclusión: Se sugieren intervenciones para aumentar la concienciación por parte de los adultos mayores en los perfiles personalizados de afecto positivo, aliviando así los sentimientos de soledad en los que sufren limitaciones funcionales (especialmente mujeres, con síntomas depresivos, viudos, residiendo en una institución y con bajo nivel educativo).(AU)
Objective: Research has shown that loneliness is associated with functional disability in the older population. However, little is known about the role of affectivity in this relationship. The present study explored a mediation model in which affectivity was hypothesized to mediate the re-lationship between functionality and loneliness, controlling for the effect of relevant variables.Methods:The University of California Loneliness Scale-16 items, Geriatric Functionality Scale, Positive and Negative AffectSchedule-14, and Geriatric Depression Scale-8 were administered to 489 old adults (65100 years old), 428 from social care homes (SCH), and 61 from the community.Results:Those from SCH, women, widowed, withlow education, more functional disability, more negative affect, less posi-tive affect, and more depressive symptoms reported more loneliness. Con-trolling for the effect of depressive symptoms, gender, residential status, marital status, and education, only positive affect mediated, partially, the relationship between functionality and loneliness.Conclusion:We suggest implementing interventions that increase older adults' insights in personal-ized patterns of positive affect and, consequently, ease feelings of loneli-ness in older people suffering from functional limitations (especially wom-en, with depressive symptoms, widowed, residing in an institution, and with low educational level).(AU)

Background: The Mini-Addenbrooke's Cognitive Examination (M-ACE) is a valid and reliable tool that accurately differentiates various types of cognitive impairment from Normal-cognition assessed in multiple settings. However, its validity among older individuals in long-term care (LTC) was not yet established. Therefore, we sought to assess the Portuguese M-ACE's validity, reliability, and accuracy in detecting cognitive impairment no-dementia (CIND) in LTC users. Methods: A comprehensive assessment was performed on 196 LTC Portuguese users aged ≥ 60 years, among whom 71 had Normal-cognition, and 125 had CIND. Results: The M-ACE was found to be reliable (McDonald's ω = .86, Cronbach's α = .85) and consistent over time (r = .72; ICC = .83) and between raters (k = .92). Strong correlations with related measures supported construct validity (both r = .67). The M-ACE accurately distinguished CIND from Normal-cognition with a cut-off of 17 points (AUC = 0.81, Sensitivity = 81.7%, Specificity = 74.4%). Conclusion: Our findings suggest that the Portuguese M-ACE is a valid and reliable cognitive assessment tool for LTC users, allowing for accurate differentiation between CIND and Normal-cognition. Thus, the M-ACE's use could contribute to the early detection and intervention of cognitive disorders, especially among older adults in LTC.
RESUMEN
OBJECTIVES: The abbreviated 16-item version of the Difficulties with Emotion Regulation Scale (DERS-16) is widely used to assess individuals' perceived challenges in regulating their emotions, a central aspect of psychological symptoms commonly experienced in old age. However, its psychometric properties have yet to be tested in this population. Furthermore, a shorter version of the DERS-16 could further minimize the assessment burden on older individuals. Thus, we aimed to test the DERS-16's psychometric performance and determine if any items were redundant to develop a psychometrically sound shorter version. METHODS: We enrolled 302 Portuguese older adults (Mage = 75.22; SD = 8.99 years) in a cross-sectional study. RESULTS: Exploratory factor analyses indicated a one-factor structure and a four-factor solution with eight items (69.3%-81.9% of the variance observed). The four-factor-8-item solution presented an interpretable structure and demonstrated good reliability values (> 0.70) and construct validity with the Twenty-Item Toronto Alexithymia Scale, Eight-Item Geriatric Depression Scale, and Geriatric Anxiety Inventory (r = 0.66, 0.40, 0.52; p < 0.001). CONCLUSION: The robust psychometric properties of DERS-8 make it a valuable tool for clinical and longitudinal studies, facilitating targeted interventions in older adults and allowing for precise emotion dysregulation screening.

Loneliness is a prevalent set of negative feelings associated with unsatisfactory and reduced social interactions, inadequate social support, poor satisfaction with life and health, negative emotions, and economic burden. Thus, its measurement is of foremost importance. Therefore, this study aimed (i) to devise the Portuguese version of the three-Item Loneliness Scale (T-ILS), which is ideal for epidemiological studies, and (ii) to evaluate its psychometric properties. Three hundred forty-five community-dwelling Portuguese adults with a mean age of 54.6 ± 19.5 years, 61.7% women, recruited door-to-door, were assessed with the Portuguese versions of T-ILS, Satisfaction With Life Scale-SWLS, Lubben Social Network Scale 6-items-LSNS-6, a question regarding Happiness/Unhappiness, and a sociodemographic questionnaire. The T-ILS showed good psychometric properties and correlated moderately with SWLS and LSNS-6, and happiness, and weakly with the number of people in the household. The Portuguese version of the T-ILS proved to be a valid and reliable instrument, easy and quick to administer. It proved to be a valuable tool in screening loneliness in Portugal, being potentially useful to the identification of lonelier people in need of intervention.
RESUMEN
Background: Emotion dysregulation has been consistently linked to psychopathology, and the relationship between disability and depressive symptomatology in old age is well-known. Objective: To examine the mediational role of emotional dysregulation in the relationship between perceived disability and depressive symptomatology in older adults. Methods: Two hundred eighty-three participants, aged 6096 years (M±SD=74.22±8.69; 62.9% women; 29.0% with long-term care support [LTC-S] and 71.0% community residents without LTC-S), were assessed with the Geriatric Depression Scale-8 (GDS-8), the World Health Organization Disability Assessment Schedule-2 (WHODAS-2), and the Difficulties in Emotion Regulation Scale-16 (DERS-16). Results: A mediation model was established, which revealed: (1) a moderate association between WHODAS-2 and GDS-8 (β=0.20; p<.001); (2) DERS-16 partially and weakly mediated the relationship between WHODAS-2 and GDS-8 (β=0.003; p<.01). The model explained 31.9% of the variance of depressive symptoms. An inconsistent mediation model was obtained in the LTC-S group. Conclusions: Globally, our findings indicate that disability has an indirect relationship with depressive symptomatology through emotional dysregulation (except for those in the LTC-S). Accordingly, we present suggestions for the treatment of depressive symptoms and for the inclusion of other emotion regulation variables in the study of the disability-depressive symptom link in future studies with older people in the LTC-S.

Antecedentes: La desregulación de las emociones se ha relacionado sistemáticamente con la psicopatología, y es bien conocida la relación entre la discapacidad y la sintomatología depresiva en la edad avanzada. Objetivo: Examinar el papel mediador de la desregulación emocional en la relación entre la discapacidad percibida y la sintomatología depresiva en los adultos mayores. Materiales y métodos: Doscientos ochenta y tres participantes, entre 60-96 años de edad (M±DE=74,22±8,69; 62,9% mujeres; 29% con apoyo de cuidados de larga duración [A-CLD] y 71% residentes en la comunidad sin A-CLD), fueron evaluados con la Geriatric Depression Scale-8 (GDS-8), el World Health Organization Disability Assessment Schedule-2 (WHODAS-2) y la Difficulties in Emotion Regulation Scale-16 (DERS-16). Resultados: Se estableció un modelo de mediación que reveló: (1) una asociación moderada entre el WHODAS-2 y el GDS-8 (β=0,20; p<0,001); (2) el DERS-16 medió parcial y ligeramente la relación entre el WHODAS-2 y el GDS-8 (β=0,003; p<0,01). El modelo explicó el 31,9% de la varianza de los síntomas depresivos. Se ha obtenido un modelo de mediación inconsistente en el grupo A-CLD. Conclusiones: Globalmente, nuestros hallazgos indican que la discapacidad tiene una relación indirecta con la sintomatología depresiva a través de la desregulación emocional. En consecuencia, presentamos sugerencias para el tratamiento de los síntomas depresivos y para la inclusión de otras variables de regulación de las emociones en el estudio del vínculo discapacidad-síntomas depresivos en futuros estudios con personas mayores en el A-CLD.

OBJECTIVE: Assessing sleep in later life is essential for diagnosing and treating sleep problems and their consequences. We aimed to test a short questionnaire specifically designed to assess the subjective sleep quality in older people, the Geriatric Sleep Questionnaire (GSQ). METHOD: The GSQ was validated in a Portuguese sample of older people (N = 443; 65-100 years; M = 80.02; SD = 6.95). We analyzed reliability, factor validity, convergent validity with other theoretical similar constructs, discriminant validity with a theoretically divergent measure, and predictive power to detect sleep problems (ROC analysis). RESULTS: A six-item version was obtained with good reliability (Cronbach's α = 0.79), and adequate convergent and divergent validity (p < 0.01). ROC analysis revealed a sensitivity of 80.0% and a specificity of 66.7% in detecting sleep problems with a cutoff point of 16 (AUC = 0.72). Older people in social care, low education, and living in rural areas reported worse sleep quality. CONCLUSION: The GSQ-6 is a brief instrument with good psychometric characteristics to assess the subjective sleep quality in older people. The GSQ-6 seems to be a valuable tool for future investigations on the relationship of sleep quality with mental health and well-being in older people.

OBJECTIVES: Depressive symptoms are common in older adults in institutional contexts; however, there is a lack of validated measures for these settings. Identifying depressive symptoms can help clinicians to manage them and to prevent or delay their complications. This study aimed to validate the Geriatric Depression Scale (GDS) in an institutionalized sample of older adults. METHOD: 493 institutionalized older people (73% women) aged 60 or over were evaluated through the GDS, the Mini International Neuropsychiatric Interview (MINI) (depression vs. no depression = 11% vs. 89%), the Geriatric Anxiety Inventory (GAI), the Positive Affect (PA) and Negative Affect (NA) Schedule, and the Satisfaction with Life Scale (SWLS). Test-retest reliability was assessed with 57 older adults. RESULTS: An 8-item version presented a Cronbach's alpha value of .87 with a single factor explaining its variance. The correlations (p < .01) attested the concurrent validity (GAI: r = .76; PA: r = -.22; AN: r = .62; SWLS: r = -.32). Test-retest reliability (6.51 months) was adequate (r = .52). ROC analysis (AUC = .82; sensitivity = 80%; specificity = 77%) and Youden index revealed a cutoff of 5/6 for the diagnosis of depression. CONCLUSION: Results support the validity and the screening capacity of a short version of GDS in institutional contexts. Short screening instruments for depressive symptoms may facilitate their identification, allowing for timely clinical interventions in institutional settings.

Resumo Com o objetivo de efetuar o rastreio do perfil cognitivo dos residentes em Estruturas Para Idosos no Concelho de Miranda do Corvo, avaliaram-se 174 participantes recorrendo ao Mini-Mental State Examination (MMSE) (n=96) e ao diagnóstico de demência reportado nos prontuários dos pacientes (n=78). Verificou-se, através do MMSE, que 41,7% dos inquiridos apresentavam pontuações sugestivas de déficit cognitivo. Adicionando a este resultado o diagnóstico de demência reportado nos prontuários dos pacientes, a percentagem subiu para 67,8% (n=118). A comparação dos nossos resultados com os obtidos a nível nacional revelou que essa percentagem foi significativamente superior (p<0,001). A escolaridade foi um fator preditivo da pontuação do MMSE (p=0,001). Conclui-se que a elevada prevalência de suspeita de déficit cognitivo e de demência revelada no nosso estudo deve remeter para a reflexão sobre a adequação dos cuidados prestados e sobre a ausência/escassez de programas de estimulação cognitiva nas estruturas residenciais para idosos. Nesse sentido, torna-se imperativo implementar avaliação cognitiva regular e instituir programas de intervenção que promovam a conservação e melhoria do funcionamento cognitivo em pessoas idosas institucionalizadas de zonas desfavorecidas.
Abstract This study aimed to screen the cognitive profile elderly people living in long-term care institutions in the municipality of Miranda do Corvo by evaluating 174 participants with the Mini Mental State Examination (MMSE) (n=96) and the clinical dementia diagnosis (n=78). According to the MMSE, 41.7% of respondents had scores suggestive of cognitive impairment. The percentage rose to 67.8% (n=118) by adding the diagnosis of dementia reported in individual medical records to this result. The comparison of our results with those obtained nationwide showed that this proportion was significantly higher (p<0.001). The educational level was a predictive factor for MMSE scores (p=0.001). We can conclude that the high prevalence of suspected cognitive impairment and dementia revealed in our study should lead us to reflect on the quality of care provided and on the lack/scarcity of cognitive stimulation programs in long-term care institutions for seniors. Thus, it is imperative to implement regular cognitive assessment and to apply intervention programs for the preservation and improvement of the cognitive functioning of institutionalized elderly of deprived areas.

The Edinburgh Handedness Inventory (EHI) is persistently the most used inventory to evaluate handedness, being neuropsychological investigation and clinical practice. Despite this, there is no information on how this instrument functions in a Portuguese population. The objective of this study was therefore to examine the sociodemographic influences on handedness and establish psychometric properties of the EHI in a Portuguese sample. The sample consisted of 342 adults (157 men and 185 women), assessed with a battery of neuropsychological tests. The mean EHI Laterality Quotient was 63.52 (SD = 38.00). A much high percentage of ambiguous-handedness compared to left-handedness was detected. An inconsistency was found between the preference for formal education activities (writing-drawing-using scissors) and the remaining EHI activities. From sociodemographic variables, only age, area, and regions of residence showed significant influence on EHI scores. The reliability and temporal reliability of EHI were adequate. Confirmatory factor analysis indicated a one-factor model (χ2/df = 2.141; TLI = 0.972; CFI = 0.979; RMSEA = 0.058). The inconsistency between formal education and nonformal activities could be an indicator of social pressure. The present data give support for the notion that handedness measured by EHI is potentially sensitive to sociodemographic and cultural influences.

Objetivos : Constatando que a depressão é comum em idosos institucionalizados, associando-se à solidão, à ansiedade e à afetividade, pretendemos descrever a evolução da depressão durante dois anos e verificar que fatores se associam a essa evolução. Métodos : Em um estudo de coorte prospectivo em dois momentos (2011 e 2013), avaliamos 83 idosos institucionalizados, com idade no primeiro momento entre os 60 e os 100 anos, sendo 79,5% mulheres, 86,7% sem companheiro(a), e 72,3% com algum grau de escolaridade. Usamos a Escala Geriátrica da Depressão (GDS), a Escala de Solidão (UCLA-L), o Inventário Geriátrico de Ansiedade (GAI) e a Lista de Afetos Positivos e Negativos (PANAS). Resultados: Verificamos que 59,0% mantiveram a depressão e 10,8% desenvolveram depressão. Os idosos com depressão tiveram significativamente piores resultados na UCLA, GAI e PANAS, e os não depressivos tiveram afetos positivos mais altos. Quanto à evolução da depressão, os idosos que mantiveram depressão tiveram inicialmente pontuações elevadas no GDS, GAI, UCLA e na subescala PANAS negativo e pontuações baixas na subescala PANAS positivo. Esses idosos apresentaram associadamente um agravamento dos sentimentos de solidão, dos sintomas ansiosos e do afeto negativo ao longo dos dois anos. Os que desenvolveram depressão tiveram, no primeiro momento, pontuações elevadas na UCLA. Conclusões: Os sintomas de depressão com ou sem solidão no momento inicial, o agravamento da solidão, a ansiedade, o afeto negativo e o baixo afeto positivo poderão ser fatores de risco para a manutenção da depressão. A solidão poderá ainda ser um fator de risco para o desenvolvimento de depressão. .
Objectives : Knowing that depression is common in institutionalized elderly and associated with loneliness, anxiety, and affectivity, we want to describe the evolution of depression over two years and identify which factors are associated with the development of depression. Methods: In this prospective cohort study, that encompassed two evaluation moments (2011 and 2013), 83 institutionalized elders were inquired, with age at baseline between 60 and 100 years, 79.5% women, 86.7% single and 72.3% with some type of education. The instruments included the Geriatric Depression Scale (GDS), Loneliness Scale (UCLA-L), Geriatric Anxiety Inventory (GAI) and List of Positive and Negative Affects (PANAS). Results: Fifty-nine percent of the subjects maintained depression, and 10.8% developed depression. Elderly patients with depression had significantly worse outcomes in the UCLA, GAI and PANAS, and those who were not depressed had a higher positive affect. Regarding the evolution of depression, elders that maintained depression had high scores on the GDS, GAI, UCLA, and negative PANAS subscale, and low scores on the PANAS positive subscale at baseline. These elders showed an increase in the feelings of loneliness, anxiety symptoms, and negative affect over the two years. Those who developed depression had higher scores on the UCLA-L at baseline. Conclusions: We conclude that depression symptoms with or without loneliness at baseline, the worsening of loneliness, anxiety, and of the positive and negative affects may all be risk factors for the maintenance of depression. Loneliness may also be a risk factor for the development of depression. .
RESUMEN
OBJECTIVE: The Dissociative Experiences Scale (DES) is a widely used screening tool for dissociative symptoms. The aim of the present study was to evaluate the validity and internal consistency of a Portuguese version and determine if it accurately identified dissociative pathology. METHOD: The original DES underwent a "forward-backward" translation process. The translated form was used on 570 participants divided into 3 subgroups: 113 patients with dissociative symptoms, 233 psychiatric patients with various psychopathological disorders, and 224 normal individuals. RESULTS: A principal components analysis with all of the participants yielded 4 factors that accounted for 56.3% of the variance. Reliability as measured by Cronbach's alpha was .94. The receiver operating characteristic curve applied to the cutoff analysis revealed a value of 30 comparing the 2 clinical groups and contrasting the dissociative-based group with the nonclinical group. The ability of the DES to correctly classify those with and without the disease was very good. Sensitivity was 65.0% and specificity was 86.0% with the cutoff score of 30 from the comparison between dissociative symptomatic disorders and the other psychopathological disorders. Comparing the dissociative symptomatic group with the nonclinical group, we found that sensitivity was 65.0% and specificity was 100%. The mean DES scores for the 3 subgroups were significantly different. CONCLUSION: These findings are in some degree analogous to those in other studies and suggest that the DES is a reliable and valid screen for the Portuguese population.

OBJECTIVE: Conversion, dissociation and somatization are historically related in the long established concept of hysteria. Somewhere along the way they were separated due to the Cartesian dualistic view. The aim of the present study was to compare these pathologies and investigate whether symptoms of these pathologies overlap in their clinical appearance in a Portuguese sample. METHOD: Twenty-six patients with conversion disorder, 38 with dissociative disorders, 40 with somatization disorder, and a comparison group of 46 patients having other psychiatric disorders answered questions about dissociation (Dissociative Experiences Scale), somatoform dissociation (Somatoform Dissociation Questionnaire), and psychopathological symptoms (Brief Symptom Inventory). RESULTS: Dissociative and somatoform symptoms were significantly more frequent in dissociative and conversion disorder than in somatization disorder and controls. There were no significant differences between dissociative and conversion patients. CONCLUSIONS: Conversion disorder is closely related to dissociative disorders. These results support the ICD-10 categorization of conversion disorder among dissociative disorders and the hypothesis of analogous psychopathological processes in conversion and dissociative disorders versus somatization disorder.

Pathological dissociation has been extensively studied in many countries; however, little is known about it in Portugal. This research examined the role of demographic variables and mental health on dissociation in Portugal. We assessed 505 participants from 6 samples consisting of dissociative patients (n = 37), conversive patients (n = 26), somaticizing patients (n = 59), posttraumatic stress disorder patients (n = 50), other psychiatric patients (n = 174), and nonclinical subjects (n = 159). Dissociation was measured by Portuguese versions of the Dissociative Experiences Scale and Somatoform Dissociation Questionnaire; the LEAD procedure and subscales of the Brief Symptom Inventory indicated mental health. Pathological psychological dissociation was significantly more frequent in women, in the youngest of the participants, and in those with less education. Multiple logistic regression revealed that psychoticism, paranoid ideation, and depression symptoms made both men and women more vulnerable to psychological dissociation. Furthermore, psychological dissociation was more probable in men having symptoms of obsession and paranoid ideation and in women having symptoms of psychoticism and paranoid ideation. Pathological somatoform dissociation was significantly more probable in women with less education. Moreover, somatoform dissociation was more likely in women with somatization symptoms and more likely in men with symptoms of somatization and psychoticism. Even though significant associations were found, causal relations could not be established because the study was cross-sectional.

OBJECTIVE: The Somatoform Dissociation Questionnaire is a self-report questionnaire that has proven to be a reliable and valid instrument. The objectives of this study were to validate the Portuguese version and to determine its capability to distinguish patients with dissociative disorders from others with psychopathological disorders. METHOD: 234 patients answered the translated version of Somatoform Dissociation Questionnaire. The Portuguese Dissociative Disorders Interview Schedule was used to validate clinical diagnosis. Patients with dissociative disorder (n = 113) were compared to a control group of 121 patients with various anxiety and depression disorders. RESULTS: Reliability measured by Cronbach's a was 0.88. The best performance of the Portuguese form was at a cut-off point of 35, which distinguishes between dissociative disorder and neurotic disorders with a good diagnostic efficacy (sensitivity = 0.73). The somatoform dissociation was significantly more frequent in dissociative disorder patients, conversion disorder patients and post-traumatic stress disorder patients. CONCLUSIONS: These findings suggest that dissociative disorders can be differentiated from other psychiatric disorders through somatoform dissociation. The Portuguese version of the Somatoform Dissociation Questionnaire has fine psychometric features that sustain its cross-cultural validity.
