There is a consensus in the literature indicating that patients with Bipolar Disorder (BD) show cognitive impairments, especially in executive function, during both acute episodes and euthymia.1 An emerging body of knowledge indicates the importance of promoting functional recovery and improving cognitive deficits to achieve an adequate treatment of BD. However, the trajectories of cognitive deficits are still unclear. The neuroprogression hypothesis suggests that BD may present a progressive course with cognitive and functioning decline, which may be associated with mood episodes, length of the illness, early trauma,2 and biological rhythms disturbance, which may be a feature of BD.3 However, most of the evidence in this field came from cross-sectional studies, and the few existing longitudinal studies bring contrary results.4 A small number of studies assess the patient's perception of their cognitive function, which might be highly relevant to their everyday life.5 Therefore, the ideal study to assess the progression of cognition in BD might include objective as well as subjective measures from a longitudinal perspective.Thus, the purpose of the present study was to evaluate longitudinal cognitive performance in a sample of individuals with BD at baseline and after six years. All patients were in a depressive episode at baseline and euthymic at follow-up. We assessed subjective and objective cognitive difficulties in both points. We also investigated the relationship between psychosocial functioning, biological rhythms, and childhood trauma to cognition and the course of the illness. As far as we know, this is the first report using specific instruments to measure the relationship between these aspects to objective and subjective cognitive difficulties in a longitudinal BD sample.

Objective: As the older population increases, it is important to identify factors that may reduce the risks of dementia in the general population. One such factor is the concept of cognitive reserve (CR). The present study analyzed the psychometric properties of the Cognitive Reserve Assessment Scale in Health (CRASH) in the Brazilian population. This scale was originally developed to measure CR in individuals with severe mental illness. We also investigated the relationship between the CRASH and clinical or sociodemographic variables. Methods: This study was conducted with 398 individuals. We assessed sociodemographic variables and depression, anxiety, and stress symptoms (Depression, Anxiety and Stress Scale [DASS-21]) using a web-based survey. We constructed a confirmatory factor analysis (CFA) model in order to test the goodness of fit of the factor structure proposed in the original CRASH study. Results: The McDonald's hierarchical ω for CRASH using CFA parameters was 0.61, and the Cronbach's alpha coefficient indicated good internal consistency when considering all items (alpha = 0.7). Conclusions: Our results suggest that CRASH can be used to assess CR in the general population in Brazil.
RESUMEN
INTRODUCTION: The impact of restrictive measures during the COVID-19 pandemic resulted in negative effects on the Quality of Life (QoL). It is important to evaluate this measure in a specific region with a homogeneous profile and with high rates of transmission during the pandemic in a developing nation as Brazil. OBJECTIVES: The objective of this study was to assess through an online self-reported questionnaire the impact of COVID-19 pandemic on QoL in a specific region in the South of Brazil, called "Vale do Taquari", in the initial stage of the COVID-19 outbreak. METHODS: This study was conducted with 325 individuals. We assessed sociodemographic variables and depression, anxiety, stress symptoms (Depression, Anxiety and Stress Scale-21 (DASS-21), sleep quality (The Pittsburgh Sleep Quality Index PSQI), post-traumatic stress symptoms (Impact of Event Scale-IES-R scale) and QoL (The World Health Organization quality of life assessment (WHOQOL-bref). RESULTS: Reduced psychological symptoms, better sleep quality, shorter duration of social isolation, not experiencing stressful situations during the pandemic, higher education and older age were associated with increased QoL. CONCLUSION: Our results could be used as a historical reference and help assist local authorities to define future intervention strategies, since we will probably need to deal with the deleterious effects of the pandemic even after its complete control.(AU)

Abstract Introduction Social isolation has been associated with poor sleep quality and mental health problems during the COVID-19 pandemic. However, most studies have investigated heterogeneous samples subjected to varying social distancing policies and did not focus on a single local profile subject to homogeneous prevention policies. Objective To evaluate the impact of the COVID-19 pandemic on mental health and sleep quality in a specific region in the South of Brazil where the populations have similar culture and local governments have adopted similar social distancing policies. Methods This study was conducted with 327 individuals aged 18-72 years, living in the Vale do Taquari area, Brazil. We assessed sociodemographic variables with a standardized protocol, symptoms of depression, anxiety, and stress with the Depression, Anxiety and Stress Scale-21 (DASS-21), sleep quality with the Pittsburgh Sleep Quality Index (PSQI), and post-traumatic stress symptoms with the Impact of Event Scale (IES-R), using a web-based online survey. Results Our results showed that sleep dysfunction moderated the effects of age on psychological symptoms, indicating that younger participants who had poorer sleep quality had worse mental health. Furthermore, participants with more perceived stress during the pandemic and more sleep dysfunction reported more symptoms of anxiety and post-traumatic stress. Conclusion Psychological symptoms were not related to social isolation duration but were related to the subjective perception that the pandemic interfered with life and generated stressful situations. These results may help governments make important decisions about protection and isolation measures in future waves of COVID-19 infection.
RESUMEN
The notion that schizophrenia is a neuroprogressive disorder is based on clinical perception of cumulative impairments over time and is supported by neuroimaging and biomarker research. Nevertheless, increasing evidence has indicated that schizophrenia first emerges as a neurodevelopmental disorder that could follow various pathways, some of them neuroprogressive. The objective of this review is to revisit basic research on cognitive processes and neuroimaging findings in a search for candidate keys to the intricate connections between neurodevelopment and neuroprogression in schizophrenia. In the complete panorama, schizophrenia is a neurodevelopmental disorder, possibly associated with an additional burden over the course of the disease through pathologically accelerated aging, and cognitive heterogeneity may explain the different trajectories of each patient.
RESUMEN
Abstract Objective To investigate associations between body mass index (BMI), white matter fractional anisotropy (FA), and C-reactive protein (CRP) in a group of individuals with bipolar disorder (BD) during euthymia and compare them with a control group of healthy subjects (CTR). Methods The sample consisted of 101 individuals (BD n = 35 and CTR n = 66). Regions of interest (ROI) were defined using a machine learning approach. For each ROI, a regression model tested the association between FA and BMI, controlling for covariates. Peripheral CRP levels were assayed, correlated with BMI, and included in a mediation analysis. Results BMI predicted the FA of the right cingulate gyrus in BD (AdjR2 = 0.312 F(3) = 5.537 p = 0.004; β = -0.340 p = 0.034), while there was no association in CTR. There was an interaction effect between BMI and BD diagnosis (F(5) = 3.5857 p = 0.012; Fchange = 0.227 AdjR2 = 0.093; β = -1.093, p = 0.048). Furthermore, there was a positive correlation between BMI and CRP in both groups (AdjR2 = 0.170 F(3) = 7.337 p < 0.001; β = 0.364 p = 0.001), but it did not act as a mediator of the effect on FA. Conclusion Higher BMI is associated with right cingulate microstructure in BD, but not in CTR, and this effect could not be explained by inflammatory mediation alone.
RESUMEN
In a pandemic, it is necessary to understand who is at higher risk for psychological difficulties. Thus, we aim to investigate psychological symptoms in a Brazilian sample during the COVID-19 pandemic and their associations with sociodemographic, health, and pandemic-related variables. We included 1358 individuals assessed via an online survey through a questionnaire that included sociodemographic and other questions related to the pandemic and the SRQ-20. The results showed that younger adults and women were at a higher risk for minor mental disorders. An investigation about subgroups revealed three clusters representing symptom's severity. The cluster with most symptoms was younger people, had their income most impacted by the pandemic, and had more frequent diagnoses of mental disorders. The subgroups were discriminated mostly due to cognitive-emotional symptoms. We discussed the determinants that can contribute to mental health vulnerability and highlighted the need for state actions for those more vulnerable.
Em uma pandemia, é necessário entender quem possui maior risco de dificuldades psicológicas. O objetivo deste estudo foi investigar os sintomas psicológicos mais prevalentes em uma amostra brasileira, durante a pandemia da COVID-19 e associações com variáveis sociodemográficas, de saúde e pandêmicas. 1.358 indivíduos responderam a um survey online por meio de questionário, que incluiu questões sociodemográficas e relacionadas à pandemia, e o SRQ-20. Os resultados mostraram que mais jovens e mulheres estão em maior risco de transtornos mentais menores (MMD). Uma investigação sobre subgrupos revelou três grupos que representam a gravidade dos sintomas. O cluster com mais sintomas era mais jovem, teve sua renda mais impactada pela pandemia e tinha diagnósticos de transtornos mentais mais frequentemente. Os subgrupos foram discriminados principalmente devido a sintomas cognitivo-emocionais. Discutimos os determinantes que podem contribuir para a vulnerabilidade em saúde mental e destacamos a necessidade de ações estatais para os mais vulneráveis.

For years, the management of schizophrenia has represented a challenge for clinicians, with antipsychotic treatments usually resulting in relapses and new hospitalizations. Clozapine has been shown to be an effective medication for treatment-resistant schizophrenia (TRS), but is currently underused due to its potential side effects. Nevertheless, research has suggested that clozapine reduces future hospitalizations in patients with TRS. This study aims to verify the rates of hospitalizations in patients with TRS under long-term use of clozapine. We retrospectively analyzed clinical data from 52 individuals with TRS before and after the use of clozapine. The mean duration of treatment with and without clozapine was 6.6 (± 3.9) and 8.5 years (± 6.6), respectively. Patients had a median of 0.5 (0.74) hospitalizations per year before the use of clozapine and 0 (0.74) hospitalizations after it (p = 0.001). Therefore, the use of clozapine resulted in an expected reduction in the number of hospitalizations per year in individuals with TRS. (AU)

Abstract Background Emotional memory is an important type of memory that is triggered by positive and negative emotions. It is characterized by an enhanced memory for emotional stimuli which is usually coupled with a decrease in memory of neutral preceding events. Emotional memory is strongly associated with amygdala function and therefore could be disrupted in neuropsychiatric disorders. To our knowledge, there is no translated and culturally adapted instrument for the Brazilian Portuguese speaking population to assess emotional memory. Objective To report the translation and cross-cultural adaptation of a Brazilian Portuguese version of the Emotional Memory Scale, originally published by Strange et al. in 2003. Methods The author of the original scale provided 36 lists with 16 words each. Translation was performed by three independent bilingual translators. Healthy subjects assessed how semantically related each word was within the list (0 to 10) and what the emotional valence of each word was (-6 to +6). Lists without negative words were excluded (negative selection), most positive and most unrelated words were excluded (positive and semantic selection, respectively), and lists with low semantic relationship were excluded (semantic assessment). Results Five lists were excluded during negative selection, four words from each list were excluded in positive and semantic selection, and 11 lists were excluded during semantic assessment. Finally, we reached 20 lists of semantically related words; each list had one negative word and 11 neutral words. Conclusion A scale is now available to evaluate emotional memory in the Brazilian population and requires further validation on its psychometrics properties.
Resumo Introdução Memória emocional é um tipo importante de memória que é acionado por emoções positivas e negativas. Ela é caracterizada por um aumento de memória para estímulos emocionais que normalmente está associado a um prejuízo de memória para eventos neutros que os precedem. Memória emocional é fortemente relacionada à função da amígdala e, portanto, pode estar alterada em transtornos neuropsiquiátricos. Pelo nosso conhecimento, não existe instrumento traduzido e adaptado culturalmente para a população falante de português brasileiro para avaliar memória emocional. Objetivo Descrever a tradução e adaptação transcultural para o português brasileiro da Escala de Memória Emocional, originalmente publicada por Strange et al. em 2003. Métodos O autor da escala original forneceu 36 listas com 16 palavras cada. A tradução foi feita por três tradutores bilíngues e independentes. Sujeitos saudáveis foram selecionados para avaliar o quanto cada palavra era semanticamente relacionada dentro da lista (0 a 10) e qual era a valência emocional de cada palavra (-6 a +6). Listas sem palavras negativas foram excluídas (seleção negativa), palavras mais positivas e menos relacionadas de cada lista foram excluídas (seleções positiva e semântica, respectivamente) e listas com relação semântica fraca foram excluídas (avaliação semântica). Resultados Cinco listas foram excluídas durante a seleção negativa, quatro palavras de cada lista foram excluídas nas seleções positiva e semântica, e 11 listas foram excluídas na avaliação semântica. Por fim, chegamos em 20 listas de palavras semanticamente relacionadas; cada lista com uma palavra negativa e 11 palavras neutras. Conclusão Uma escala está disponível para avaliar memória emocional na população brasileira e requer posterior validação de suas propriedades psicométricas.

Abstract Introduction The Internet has seen rapid growth in the number of websites focusing on mental health content. Considering the increased need for access to accurate information about mental health treatment, it is important to understand the promotion of this information online. Objective To analyze BuzzFeed's Mental Health Week (BFMHW) interactions on its own website and in related social media platforms (Facebook, Twitter and YouTube) using metrics of information delivery in mental health topics. Methods We extracted social media metrics from the 20 posts with the highest number of BuzzFeed interactions on the BFMHW website and from 41 videos available on the BFMHW playlist created by the BuzzFeed Video profile on YouTube. We analyzed the format and content used in BuzzFeed's publishing methods as well as the following social media metrics: exposure (presence online, views and time online), influence (likes) and engagement (comments, shares, replies and BuzzFeed interactions). Results Analysis of the variables revealed that audience engagement is associated with the number of medias in which the content is published: views on YouTube and shares on Facebook (0.71, p<0.001), total interactions on Facebook (0.66, p<0.001) and BuzzFeed number of total interactions (0.56, p<0.001). Conclusions Our results suggest that videos on YouTube may be an important information channel, including activity and engagement on other medias such as Facebook. Information may be more effective in reaching the audience if it is delivered in more than one media and includes personal experiences, some humor in content and detailed information about treatment.
Resumo Introdução O número de sites com foco em conteúdo de saúde mental vem crescendo rapidamente. Considerando a necessidade crescente de acesso a informações precisas sobre tratamento em saúde mental, é importante entender a promoção dessas informações on-line. Objetivo Analisar as interações da Semana de Saúde Mental do BuzzFeed (BuzzFeed's Mental Health Week - BFMHW) em seu próprio site e em plataformas de mídia social relacionadas (Facebook, Twitter e YouTube) usando métricas de entrega de informações em tópicos de saúde mental. Métodos Extraímos métricas de mídias sociais das 20 postagens com o maior número de interações no site da BFMHW e de 41 vídeos disponíveis na playlist da BFMHW criada pelo perfil BuzzFeed Video no YouTube. Analisamos o formato e o conteúdo usados nos métodos de publicação do BuzzFeed, bem como as seguintes métricas de mídias sociais: exposição (presença on-line, visualizações e tempo on-line), influência (curtidas) e engajamento (comentários, compartilhamentos, respostas e interações do BuzzFeed). Resultados A análise das variáveis revelou que o envolvimento do público está associado ao número de mídias em que o conteúdo é publicado: visualizações no YouTube e compartilhamentos no Facebook (0,71, p <0,001), interações totais no Facebook (0,66, p <0,001) e número de interações totais no BuzzFeed (0,56, p <0,001). Conclusões Nossos resultados sugerem que o YouTube pode ser um importante canal de informações, incluindo atividades e envolvimento em outras mídias, como o Facebook. As informações podem alcançar o público de forma mais eficaz se forem exibidas em mais de uma mídia e incluírem experiências pessoais, algum humor no conteúdo e informações detalhadas sobre o tratamento.

Objective: To assess cognitive performance and psychosocial functioning in patients with bipolar disorder (BD), in unaffected siblings, and in healthy controls. Methods: Subjects were patients with BD (n=36), unaffected siblings (n=35), and healthy controls (n=44). Psychosocial functioning was accessed using the Functioning Assessment Short Test (FAST). A sub-group of patients with BD (n=21), unaffected siblings (n=14), and healthy controls (n=22) also underwent a battery of neuropsychological tests: California Verbal Learning Test (CVLT), Stroop Color and Word Test, and Wisconsin Card Sorting Test (WCST). Clinical and sociodemographic characteristics were analyzed using one-way analysis of variance or the chi-square test; multivariate analysis of covariance was used to examine differences in neuropsychological variables. Results: Patients with BD showed higher FAST total scores (23.90±11.35) than healthy controls (5.86±5.47; p < 0.001) and siblings (12.60±11.83; p 0.001). Siblings and healthy controls also showed statistically significant differences in FAST total scores (p = 0.008). Patients performed worse than healthy controls on all CVLT sub-tests (p < 0.030) and in the number of correctly completed categories on WCST (p = 0.030). Siblings did not differ from healthy controls in cognitive tests. Conclusion: Unaffected siblings of patients with BD may show poorer functional performance compared to healthy controls. FAST scores may contribute to the development of markers of vulnerability and endophenotypic traits in at-risk populations.

Objectives: Depressive symptoms are associated with worse outcomes in patients with bipolar disorder (BD). However, scarce data are available regarding neurocognitive profiles across different areas of functioning among BD patients with moderate and severe depression. Our objective was to assess cognition and global functioning in a group of patients with bipolar depression. Methods: Data were available for 100 patients with bipolar depression (78% female) and 70 controls (64% female) paired by age and education level. Cognitive function was assessed with a neuropsychological test battery. Functioning was assessed with the Functioning Assessment Short Test. Results: In patients, severe depression was associated with poorer cognitive performance on measures of executive function. Patients with severe depression showed worse global functioning than those with moderate depression (z = 2.54, p = 0.011). In patients with severe depression, lower global functioning was associated with lower scores in working memory (r = -0.200, p = 0.010), and executive function (r = -0.210, p = 0.007; and r = 0.293, p < 0.001). Conclusion: Our findings suggest cognitive impairment and global functioning impairment are associated with the severity of depressive symptoms in bipolar depression. Intensive treatment of depressive symptoms in patients with BD is crucial to improve cognitive functioning and, consequently, functional outcomes.

INTRODUCTION: Schizophrenia is frequently associated with a debilitating course and prominent impairment in social and occupational functioning. Although the criteria for classification into stages have not been defined in the literature, illness duration and functioning seem to be good candidates. OBJECTIVE: To compare functioning of patients with schizophrenia at different stages of the disease (early vs. late) and healthy sex- and age-matched controls. METHODS: This double-blinded, case-controlled study included 79 individuals: 23 patients with schizophrenia diagnosed up to 5 years earlier; 19 patients with schizophrenia diagnosed at least 20 years earlier; and healthy matched controls. Diagnoses were established using the Structured Clinical Interview for Diagnostic and Statistical Manual of Mental Disorders, 4th edition (DSM-IV) Axis I Disorder. Functioning was assessed using the Functioning Assessment Short Test (FAST). RESULTS: Patients in the early stage had significantly higher scores than healthy controls in total FAST and in autonomy, occupational functioning, cognitive functioning and interpersonal relationships. Individuals in the late stage had significantly poorer functioning than controls in all domains. The comparison of functioning between the two groups of patients revealed no significant differences, except in occupational functioning, in which late stage patients had a poorer performance. CONCLUSION: Functioning impairment in schizophrenia tends to remain stable despite illness duration. Therefore, functioning should be effectively assessed at an early stage, as illness duration alone may not be the most reliable criterion to stage patients with schizophrenia (AU)
INTRODUÇÃO: A esquizofrenia está frequentemente associada a um curso debilitante e a um importante comprometimento no funcionamento social e ocupacional. Embora os critérios para classificação em diferentes estágios ainda não tenham sido definidos, a duração da doença e a funcionalidade têm sido apontadas como bons candidatos. OBJETIVO: Comparar a funcionalidade de indivíduos com esquizofrenia no estágio inicial e final com controles saudáveis correspondentes em idade e sexo. MÉTODOS: Neste estudo caso-controle, duplo-cego, foram incluídos 79 pacientes: 23 com diagnóstico de esquizofrenia feito até 5 anos atrás (estágio inicial); 19 diagnosticados há pelo menos 20 anos (estágio final); e controles saudáveis pareados. O diagnóstico foi estabelecido pela Entrevista Clínica Estruturada para Transtornos do Eixo I do Manual Diagnóstico e Estatístico de Transtornos Mentais, 4ª edição (DSM-IV). A funcionalidade foi avaliada através da escala Teste Breve de Avaliação Funcional (FAST). RESULTADOS: Os pacientes em estágio inicial tiveram escores significativamente maiores do que controles saudáveis na escala FAST (escore total e domínios autonomia, funcionamento ocupacional, funcionamento cognitivo e relações interpessoais). Os indivíduos em estágio final apresentaram funcionalidade pior que os controles em todos os domínios. A comparação entre os dois grupos não mostrou diferenças, exceto no funcionamento ocupacional, em que os pacientes em estágio final apresentaram um desempenho pior. CONCLUSÃO: O prejuízo da funcionalidade na esquizofrenia tende a permanecer estável ao longo da doença. Portanto, a funcionalidade deve ser avaliada nos estágios iniciais da doença, já que a duração da doença por si só pode não ser o critério mais confiável para definir o estágio de pacientes com esquizofrenia (AU)

OBJECTIVE: Summarize data on metabolic syndrome (MS) in bipolar disorder (BD). METHODS: A systematic review of the literature was conducted using the Medline, Embase and PsycInfo databases, using the keywords "metabolic syndrome", "insulin resistance" and "metabolic X syndrome" and cross-referencing them with "bipolar disorder" or "mania". The following types of publications were candidates for review: (i) clinical trials, (ii) studies involving patients diagnosed with bipolar disorder or (iii) data about metabolic syndrome. A 5-point quality scale was used to assess the methodological weight of the studies. RESULTS: Thirty-nine articles were selected. None of studies reached the maximum quality score of 5 points. The prevalence of MS was significantly higher in BD individuals when compared to a control group. The analysis of MS subcomponents showed that abdominal obesity was heterogeneous. Individuals with BD had significantly higher rates of hypertriglyceridemia than healthy controls. When compared to the general population, there were no significant differences in the prevalence of low HDL-c in individuals with BD. Data on hypertension were also inconclusive. Rates of hyperglycemia were significantly greater in patients with BD compared to the general population. CONCLUSIONS: The overall results point to the presence of an association between BD and MS, as well as between their subcomponents.

Introdução: Alterações nos ritmos circadianos tem sido frequentemente observadas entre pacientes com Transtorno do Humor Bipolar (THB). No entanto, existem poucos instrumentos para medi-las e a maioria deles mede exclusivamente distúrbios do sono. A escala BRIAN, validada para adultos com THB, avalia a regularidade dos ritmos biológicos em quatro diferentes aspectos: sono, atividades, social e padrão de alimentação. O objetivo deste estudo-piloto foi adaptar a escala BRIAN para uma população de crianças e adolescentes (BRIAN-K) e avaliar se o novo instrumento é capaz de detectar diferenças entre pacientes e controles saudáveis. Métodos: Foram avaliados 20 pacientes com THB entre 8-16 anos e 32 controles pareados por sexo e idade. Os sujeitos foram avaliados por meio de entrevista clínica, K-SADS-PL e testagem cognitiva. A BRIAN-K foi aplicada em ambos os grupos. Resultados: O grupo de pacientes com THB apresentou escores mais altos de alterações em seus ritmos circadianos pelo escore total da BRIAN-K, quando comparados com o grupo controle (p=0,022). Particularmente, maior irregularidade foi observada no domínio atividades no grupo de pacientes (p=0,001). Nossos resultados também mostraram uma correlação positiva entre a idade de diagnóstico e o domínio sono da BRIAN-K (r=0,485; p=0,03). Conclusões: Estes dados preliminares sugerem que a versão BRIAN-K, recentemente adaptada para crianças e adolescentes, é capaz de discriminar pacientes com THB e controles. Futuros estudos com maior tamanho amostral são necessários para determinar a confiabilidade, a validade interna e externa do presente instrumento.
Background: Alterations in the circadian rhythms have been frequently observed in patients with Bipolar Disorder (BD). However, there are few instruments to measure these changes, and most of them only assess sleep disorders. The BRIAN scale validated for adults with BD, evaluates the regularity of the biological rhythms in four different aspects: sleep, activities, social rhythm, and eating pattern. The objective of this pilot study was to adapt the BRIAN scale to a sample of children and adolescents (BRIAN-K) and to evaluate if the new instrument is capable of detecting differences among patients and healthy controls. Methods: Twenty patients with BD, aged between 8 and 16 years, and 32 controls matched for gender and age were included. Participants were assessed using the clinical interview Schedule for Affective Disorders and Schizophrenia for School Aged Children (K-SADS-PL) and cognitive testing. The BRIAN-K was administered to both groups. Results: The group of patients with BD had higher scores of alterations in the circadian rhythms according to the BRIAN-K total score when compared to the control group (p=0.022). Particularly, more irregularity was found in the activitiesdomain in the group of patients (p=0.001). Our results have also showed a positive correlation between the age at diagnosis and the sleep domain of the BRIAN-K(r=0.485; p=0.03). Conclusions: These preliminary data suggest that the BRIAN-K version, recently adapted for children and adolescents, can differentiate patients and controls. Future studies with a larger sample size are necessary to determine the reliability, as well as the internal and external validity of the present instrument.
