Psychometric properties of the Portuguese version of the State-Trait Anxiety Inventory applied to college students: factor analysis and relation to the Beck Depression Inventory

The psychometric properties of the Portuguese version of the trait form of the State-Trait Anxiety Inventory (STAI-T) and its relation to the Beck Depression Inventory (BDI) were evaluated in a large Brazilian college student sample containing 845 women and 235 men. STAI-T scores tended to be higher for women, singles, those who work, and subjects under 30 years. Factor analysis of the STAI-T for total sample and by gender yielded two factors: the first representing a mood dimension and the second being related to worrying or cognitive aspects of anxiety. In order to study the relation between anxiety and depression measures, factor analysis of the combination of the 21 BDI items and the 20 STAI-T items was also carried out. The analysis resulted in two factors that were analyzed according to the tripartite model of anxiety and depression. Most of the BDI items (measuring positive affectivity and nonspecific symptoms of depression) were loaded on the first factor and four STAI-T items that measure positive affectivity. The remaining STAI-T items, all of them measuring negative affect, remained in the second factor. Thus, factor 1 represents a depression dimension and factor 2 measures a mood-worrying dimension. The findings of this study suggest that, although widely used as an anxiety scale, the STAI-T in fact measures mainly a general negative affect.

Validation of the Beck Depression Inventory for a Portuguese-speaking Chinese community in Brazil

The objective of the present study was to investigate the psychometric properties and cross-cultural validity of the Beck Depression Inventory (BDI) among ethnic Chinese living in the city of São Paulo, Brazil. The study was conducted on 208 community individuals. Reliability and discriminant analysis were used to test the psychometric properties and validity of the BDI. Principal component analysis was performed to assess the BDI's factor structure for the total sample and by gender. The mean BDI score was lower (6.74, SD = 5.98) than observed in Western counterparts and showed no gender difference, good internal consistency (Cronbach's alpha 0.82), and high discrimination of depressive symptoms (75-100%). Factor analysis extracted two factors for the total sample and each gender: cognitive-affective dimension and somatic dimension. We conclude that depressive symptoms can be reliably assessed by the BDI in the Brazilian Chinese population, with a validity comparable to that for international studies. Indeed, cultural and measurement biases might have influenced the response of Chinese subjects.

Anxiety, Depression, and General Psychological Distress in Patients with Coronary Slow Flow

AbstractBackground:The relationship between psychiatric illness and heart disease has been frequently discussed in the literature. The aim of the present study was to investigate the relationship between anxiety, depression and overall psychological distress, and coronary slow flow (CSF).Methods:In total, 44 patients with CSF and a control group of 50 patients with normal coronary arteries (NCA) were prospectively recruited. Clinical data, admission laboratory parameters, and echocardiographic and angiographic characteristics were recorded. Symptom Checklist 90 Revised (SCL-90-R), Beck Depression Inventory (BDI), and Beck Anxiety Inventory (BAI) scales were administered to each patient.Results:The groups were comparable with respect to age, sex, and atherosclerotic risk factors. In the CSF group, BAI score, BDI score, and general symptom index were significantly higher than controls (13 [18.7] vs. 7.5 [7], p = 0.01; 11 [14.7] vs. 6.5 [7], p = 0.01; 1.76 [0.81] vs. 1.1[0.24], p = 0.01; respectively). Patients with CSF in more than one vessel had the highest test scores. In univariate correlation analysis, mean thrombolysis in myocardial infarction (TIMI) frame counts were positively correlated with BAI (r = 0.56, p = 0.01), BDI (r = 0.47, p = 0.01), and general symptom index (r = 0.65, p = 0.01). The psychiatric tests were not correlated with risk factors for atherosclerosis.Conclusion:Our study revealed higher rates of depression, anxiety, and overall psychological distress in patients with CSF. This conclusion warrants further studies.

Sexual dysfunction and dissatisfaction in chronic hepatitis C patients

IntroductionThe prevalence of sexual dysfunction (SD) and dissatisfaction with sexual life (DSL) in patients with chronic hepatitis C virus infection (CHC) was jointly investigated via a thorough psychopathological analysis, which included dimensions such as fatigue, impulsiveness, psychiatric comorbidity, health-related quality of life (HRQL) and sociodemographic and clinical characteristics.MethodsMale and female CHC patients from an outpatient referral center were assessed using the Brief Fatigue Inventory, the Barrat Impulsiveness Scale, the Beck Depression Inventory (BDI), the Hospital Anxiety and Depression Scale, the Hamilton Anxiety Scale (HAM-A), and the World Health Organization Quality of Life Scale-Brief Version (WHOQOL-BREF). Structured psychiatric interviews were performed according to the Mini-International Neuropsychiatric Interview. SD was assessed based on specific items in the BDI (item 21) and the HAM-A (item 12). DSL was assessed based on a specific question in the WHOQOL-BREF (item 21). Multivariate analysis was performed according to an ordinal linear regression model in which SD and DSL were considered as outcome variables.ResultsSD was reported by 60 (57.1%) of the patients according to the results of the BDI and by 54 (51.4%) of the patients according to the results of the HAM-A. SD was associated with older age, female gender, viral genotype 2 or 3, interferon-α use, impulsiveness, depressive symptoms, antidepressant and benzodiazepine use, and lower HRQL. DSL was reported by 34 (32.4%) of the patients and was associated with depressive symptoms, anxiety symptoms, antidepressant use, and lower HRQL.ConclusionsThe prevalence of SD and DSL in CHC patients was high and was associated with factors, such as depressive symptoms and antidepressant use. Screening and managing these conditions represent significant steps toward improving medical assistance and the HRQL of CHC patients.

Modalidade de terapia renal substitutiva como preditora de sintomas depressivos

Objetivos Comparar a ocorrência de sintomas depressivos entre dois grupos homogêneos de pacientes em diálise, um em hemodiálise (HD) e outro em diálise peritoneal (DP), verificando o possível papel preditor do método, assim como avaliar a influência de variáveis sociodemográficas e clínicas no diagnóstico deste transtorno. Métodos Amostra envolveu dois grupos homogêneos de pacientes em TRS, 30 em HD e 30 em DP. Aplicou-se o Beck Depression Inventory (BDI), escala que avalia a presença e intensidade de sintomas depressivos. Resultados Os grupos apresentavam características sociodemográficas e clínicas semelhantes, exceto quanto à escolaridade. A média de pontos do BDI no grupo HD foi maior que no grupo DP: 12,53 versus 11,13 (p = 0,352). A presença de sintomas depressivos no grupo em HD ocorreu em 36,7% dos pacientes contra apenas 23,3% do grupo DP (OR 1,9 [IC 0,61 – 5,86]). Não houve diferenças quanto às variáveis, exceto escolaridade. Dos pacientes com ensino fundamental I, 52,9% apresentaram sintomas. Nos pacientes com ensino médio ou superior, a ocorrência de sintomas depressivos foi 20% (p = 0,051). Conclusão Houve tendência à ocorrência de sintomas depressivos em pacientes em HD quando comparados aos pacientes em DP. O risco dessa ocorrência foi quase duas vezes maior nos em HD. Menor escolaridade associou-se à ocorrência de sintomas. As médias da pontuação do BDI nos dois grupos não foram significantes.

Factors associated with depressive symptoms in a sample of Brazilian medical students

OBJECTIVES: 1 - Verify the prevalence of depressive symptoms in first to fourth-year medical students using the Beck Depression Inventory (BDI). 2 - Establish correlations between target factors and higher or lower BDI scores. 3 - Investigate the relationship between the prevalence of depressive symptoms and the demand for psychological care offered by the Centro Universitário Lusíada. METHOD: Cross-sectional study of 290 first to fourth-year medical students; implementation of the BDI, socio-demographic survey, and evaluation of satisfaction with progress. RESULTS: The study sample was 59% female and 41% male. Mean BDI was 6.3 (SD 5.8). Overall prevalence of depressive symptoms was 23.1%. The following associations were statistically significant (p<0.05): among students for whom the course failed to meet original expectations, who were dissatisfied with the course, or who came from the interior of the State (20.5%, 12.5%, and 24.4% of the total sample, respectively), for 40%, 36.1% and 36.4%, respectively, the BDI was consistent with some degree of depression. CONCLUSION: The study showed that there is higher prevalence of depressive symptoms in medical students than in the general population

Prevalência de Síndromes Funcionais em Estudantes e Residentes de Medicina

RESUMO O curso universitário é gerador de estresse, e, de acordo com a literatura, há elevada prevalência de sintomas depressivos e transtornos emocionais em até metade dos universitários. Cerca de um terço das pessoas com síndromes funcionais ou síndromes somáticas funcionais (SSF) sofre de ansiedade ou depressão. Percebe-se, assim, a associação das SSF com fatores psicossociais e estresse. Objetivo Verificar a prevalência de síndrome funcional em estudantes e residentes de Medicina. Métodos Foram entrevistados 200 estudantes da Faculdade de Medicina da Universidade Federal de Minas Gerais (UFMG) que cursavam o quinto, sexto, nono e décimo períodos, sendo 25 homens e 25 mulheres de cada período, bem como 27 residentes de várias especialidades do Hospital das Clínicas da UFMG (11 homens e 16 mulheres). Os voluntários responderam aos questionários Beck Depression Inventory (BDI) e Stait-Trait Anxiety Inventory (Stai), ambos validados no Brasil para avaliação da depressão e ansiedade, e a questionário para verificar a presença de síndromes funcionais. Resultados Oitenta e sete indivíduos (38,3%) tiveram o diagnóstico de síndrome somática e funcional (SSF), sendo prevalente nos residentes (48,1%) e nos alunos do quinto ano (43%) e menor nos alunos do terceiro ano (30%). Mulheres e seguidores da religião espírita foram os que apresentaram maior associação com SSF (p < 0,05), assim como os que possuíam maiores pontuações no questionário de avaliação de depressão e aqueles em período de formação mais avançado no curso médico. A SSF foi mais encontrada em estudantes com idade menor que 24 anos (39,4%), com renda inferior a dez salários mínimos (53,2%), casados (46,7%), com filhos (80%), entre os que possuíam parentesco médico (40,8), em tabagistas e alcoolistas (58,5%) e em estudantes com traços de ansiedade alta (45,6%). Conclusão As síndromes funcionais são frequentes entre os estudantes e residentes de Medicina. Elas ocorrem mais no sexo feminino e em deprimidos em períodos de maior tensão emocional.

Sexualidade e depressão em gestantes com aborto espontâneo de repetição

OBJETIVO: Comparar os sintomas de depressão e o comportamento sexual de gestantes com histórico de aborto espontâneo de repetição (AER) com gestantes que não vivenciaram AER.MÉTODOS: Trata-se de um estudo prospectivo caso-controle. O primeiro grupo é formado por mulheres que apresentaram AER e o segundo, por primigestas. Foram utilizados o Beck Depression Inventory (BDI), o Female Sexual Function Index (FSFI) e mais um questionário desenvolvido pelos autores sobre aspectos emocionais decorrentes da relação sexual na gravidez. Para comparar as variáveis quantitativas, com distribuição normal, utilizou-se o teste t de Student, e as variáveis categóricas foram comparadas com base no teste do χ2 ou no teste exato de Fisher. A significância estatística foi considerada para valores de p<0,05.RESULTADOS: O BDI indicou frequência aproximadamente duas vezes maior de depressão no Grupo AER (19,9 versus 10,0%, respectivamente). Quanto à função sexual, os escores médios do FSFI foram de 21,1 e 16,4 (p<0,05), respectivamente nos Grupos AER e Controle, embora apenas no âmbito do desejo (média: 3,4±1,3 para o Grupo AER e 3,7±1,1 para o Grupo Controle) não houvesse diferença significante (p=0,1). Observamos que, independentemente de a gestante ter ou não histórico de AER, quanto maior o escore de depressão, menor o escore de sexualidade (r=-0,3).CONCLUSÕES: Gestantes do Grupo AER apresentam depressão com frequência duas vezes mais elevada e função sexual mais comprometida. Há associação inversa entre depressão e função sexual.

Negative emotions affect postoperative scores for evaluating functional knee recovery and quality of life after total knee replacement

This study aimed to determine whether psychological factors affect health-related quality of life (HRQL) and recovery of knee function in total knee replacement (TKR) patients. A total of 119 TKR patients (male: 38; female: 81) completed the Beck Anxiety Inventory (BAI), Beck Depression Inventory (BDI), State Trait Anxiety Inventory (STAI), Eysenck Personality Questionnaire-revised (EPQR-S), Knee Society Score (KSS), and HRQL (SF-36). At 1 and 6 months after surgery, anxiety, depression, and KSS scores in TKR patients were significantly better compared with those preoperatively (P<0.05). SF-36 scores at the sixth month after surgery were significantly improved compared with preoperative scores (P<0.001). Preoperative Physical Component Summary Scale (PCS) and Mental Component Summary Scale (MCS) scores were negatively associated with extraversion (E score) (B=-0.986 and -0.967, respectively, both P<0.05). Postoperative PCS and State Anxiety Inventory (SAI) scores were negatively associated with neuroticism (N score; B=-0.137 and -0.991, respectively, both P<0.05). Postoperative MCS, SAI, Trait Anxiety Inventory (TAI), and BAI scores were also negatively associated with the N score (B=-0.367, -0.107, -0.281, and -0.851, respectively, all P<0.05). The KSS function score at the sixth month after surgery was negatively associated with TAI and N scores (B=-0.315 and -0.532, respectively, both P<0.05), but positively associated with the E score (B=0.215, P<0.05). The postoperative KSS joint score was positively associated with postoperative PCS (B=0.356, P<0.05). In conclusion, for TKR patients, the scores used for evaluating recovery of knee function and HRQL after 6 months are inversely associated with the presence of negative emotions.

Desesperança, ideação suicida e depressão em pacientes renais crônicos em tratamento por hemodiálise ou transplante

Introdução: Sintomas de desesperança, ideação suicida e depressão influenciam na qualidade e expectativa de vida de doentes renais crônicos. Objetivo: Avaliar se existe diferença nos sintomas de desesperança, ideação suicida e depressão entre pacientes renais crônicos em hemodiálise ou transplantados. Analisamos também se variáveis sociodemográficas como atividade laboral, ter dependentes, sexo e estado civil interferem nesses sintomas. Métodos: Estudo comparativo, de corte transversal, em que 50 pacientes em hemodiálise crônica e 50 transplantados renais, clinicamente estáveis, sem psicopatologias, pareados por sexo e idade, foram selecionados aleatoriamente. Instrumentos -Beck Hopelessness Scale (BHS), Beck Scale for Suicide Ideation (BSI) e Beck Depression Inventory (BDI). Resultados: BHS: 2% de cada grupo tiveram escore > 8 (p = 1,00). BSI: 4% em hemodiálise e 6% dos transplantados tinham escore > 1 (p = 1,00). BDI: 20% em hemodiálise e 12% dos transplantados apresentaram escore > 14 (p = 0,275). Não houve relação entre as variáveis testadas e os sintomas de desesperança e ideação suicida. Não exercer atividade laboral implicou mais sintomas depressivos (escore médio BDI: 10,5 vs. 7,3, p = 0,027). Transplantados de doadores falecidos apresentaram mais sintomas depressivos comparados aos receptores de doadores vivos (escore médio BDI: 11,0 vs. 6,7, p = 0,042). Conclusão: Não houve diferença na intensidade dos sintomas de desesperança, ideação suicida e depressão entre pacientes estáveis em hemodiálise e transplantados. Não exercer atividade laboral e receber transplante de doador falecido levou a mais sintomas depressivos. A prevalência de ideação suicida e sintomas depressivos, nas duas modalidades, merece atenção e indica a necessidade de monitorização e cuidados nesses pacientes.

Effects of type of physical exercise and leisure activities on the depression scores of obese Brazilian adolescent girls

Several studies have indicated that depressive states may lead to hypokinesia with diminished metabolic rate and energy use. Hypokinesia associated with certain eating behaviors may lead to an unfavorable energy balance that can contribute to the emergence and prevalence of obesity among children and adults. The purpose of the present study was to examine the possibility of reducing depression inventory scores in female adolescents with third-degree obesity while testing the effectiveness of different exercise programs in reducing anxiety and depression scores. The sample consisted of 40 female subjects (mean age 16 ± 1.56 years) divided into 4 groups (aerobic training, anaerobic training, leisure activities, and control). Subjects had a body mass index of 95% or more in relation to the 50th percentile. The aerobic program consisted of three ergometric bicycle sessions per week over a 3-month period (12 weeks) and the activities were prescribed after determining the anaerobic ventilatory threshold (VO2 threshold). Anaerobic training was based on the Wingate anaerobic power test. The leisure program consisted of a varied range of activities (games, exercises, etc.). A nutritionist interviewed the members of these two groups and the control group every week in order to adapt them to the nutritional guidelines proposed for the study. The study showed that all three programs (aerobic exercise, anaerobic exercise and leisure activities) were effective in reducing body mass. However, we found a significant reduction when analyzing the depression scores only for aerobic exercise (18.9 ± 9.33 to 10.6 ± 9.56 or 43.9%) but no significant alterations for anaerobic exercise (11.36 ± 5.23 to 9.63 ± 4.78 or 15.22%) and leisure (17.28 ± 7.55 to 15.07 ± 7.54 or 12.78%), thus indicating that in principle this type of activity could be included to improve emotional well-being of obese adolescent girls.

Anxiety and depression symptoms in recurrent painful renal lithiasis colic

Several studies have reported that symptoms of anxiety and depression are significantly associated with diseases characterized by painful crises. However, there is little information about the psychological aspects of recurrent painful episodes of renal stone disease. Our objective was to evaluate the association of symptoms of anxiety, depression and recurrent painful renal colic in a case-control study involving 64 subjects (32 cases/32 controls) matched for age and sex. Cases were outpatients with a confirmed diagnosis of nephrolithiasis as per their case history, physical examination, image examination and other laboratory exams. Patients had a history of at least two episodes within a 3-year period, and were currently in an intercrisis interval. The control group consisted of subjects seen at the Ophthalmology Outpatient Clinic of this University Hospital with only eye refraction symptoms, and no other associated disease. Symptoms of anxiety were evaluated by the State-Trait Anxiety Inventory and symptoms of depression by the Beck Depression Inventory. Statistically significant differences were observed between patients with nephrolithiasis and controls for anxiety state (P = 0.001), anxiety trait (P = 0.005) and symptoms of depression (odds ratio = 3.74; 95%CI = 1.31-10.62). The Beck Depression Inventory showed 34.5% of respondents with moderate and 6% with severe levels of depression. There was a significant linear correlation between symptoms of anxiety (P = 0.002) and depression (P < 0.001) and the number of recurrent colic episodes (anxiety-state: P = 0.016 and anxiety-trait: P < 0.001). These data suggest an association between recurrent renal colic and symptoms of both anxiety and depression.

Anxiety and depression in parents of a Brazilian non-clinical sample of attention-deficit/ hyperactivity disorder (ADHD) students

Higher prevalence rates of anxiety and depression have been reported in parents of children with attention-deficit/hyperactivity disorder (ADHD). The interaction between the burden of ADHD in offspring, a higher prevalence rate of this highly inherited disorder in parents, and comorbidities may explain this finding. Our objective was to investigate levels of ADHD, anxious and depressive symptomatology, and their relationship in parents of ADHD children from a non-clinical sample using a dimensional approach. The sample included 396 students enrolled in all eight grades of a public school who were screened for ADHD using the SNAP IV rating scale. Positive cases were confirmed through a semi-structured interview. Parents of all 26 ADHD students and 31 paired controls were enrolled. A sample of 36 parents of ADHD children (21 mothers, 15 fathers) and 30 parents of control children (18 mothers, 12 fathers) completed the Adult Self Report Scale, State-Trait Anxiety Inventory, and Beck Depression Inventory in order to investigate anxious and depressive symptomatology. Probands' mothers presented a higher level of ADHD symptomatology (with only inattention being a significant cluster). Again, mothers of ADHD children presented higher depressive and anxiety levels; however, these did not correlate with their own ADHD symptomatology. Only trait-anxiety levels were higher in ADHD mothers. Our findings suggest that: 1) anxious and depressive symptoms might be more prevalent in mothers of ADHD students; 2) anxious and depressive symptomatology might be independent of impairment associated with ADHD symptoms; 3) anxious and depressive symptoms are independent of the presence of ADHD.

Atuação multiprofissional e a saúde mental de gestantes

OBJETIVO: Identificar os transtornos afetivos não psicóticos em gestantes, intervir com grupos psicoprofiláticos e avaliar as possíveis alterações após intervenção. MÉTODOS: Foram atendidas 103 gestantes (71 adultas e 32 adolescentes) em programa comunitário no bairro Paraisópolis, na capital do Estado de São Paulo. Utilizaram-se os instrumentos: Self Reporting Questionnaire e Beck Depression Inventory. Foram realizados 10 encontros semanais, de duas horas de duração com abordagem no vínculo mãe/feto, em temas relacionados à gestante e ao bebê e esclarecimentos de dúvidas das gestantes. Para comparação da saúde mental antes e após intervenção, usou-se o teste do qui-quadrado (chi2), aceitando-se como significante p<0,05. RESULTADOS: Transtornos afetivos foram observados em 45 (43,7%) das gestantes antes da intervenção, e após, em 23 (22,3%). O impacto da intervenção sobre os transtornos afetivos foi estatisticamente significante (p=0,001). Já para a presença de depressão, antes da intervenção 21 (20,4%) gestantes apresentavam depressão, e após, 13 (12,6%), entretanto sem diferenças estatísticas significantes (p=0,133). CONCLUSÕES: A atuação multiprofissional no grupo de gestantes, tanto em adultas como em adolescentes, previne, detecta e trata transtornos afetivos presentes no período gravídico.

Depressive symptoms and harmful alcohol use in hepatitis C patients: prevalence and correlates

Introduction It is important to understand the characteristics and vulnerabilities of people who have hepatitis C because this disease is currently an important public health problem. The objective of this study was to estimate the prevalence of depressive symptoms and harmful alcohol use in patients with hepatitis C and to study the association between these outcomes and demographic, psychosocial and clinical variables. Methods This cross-sectional, descriptive and analytical study involved 82 hepatitis C patients who were being treated with pegylated interferon and ribavirin at a public university hospital. The primary assessments used in the study were the Alcohol Use Disorders Identification Test and the Beck Depression Inventory. Bivariate analyses were followed by logistic regression. Results The prevalence of depressive symptoms was 30.5% (n=25), and that of harmful alcohol use was 34.2% (n=28). Logistic regression analysis showed that individuals who were dissatisfied with their social support (OR=4.41; CI=1.00-19.33) and were unemployed (OR=6.31; CI=1.44-27.70) were at a higher risk for depressive symptoms, whereas harmful alcohol use was associated with the male sex (OR=6.78; CI=1.38-33.19) and the use of illicit substances (OR=7.42; CI=1.12-49.00). Conclusions High prevalence rates of depressive symptoms and harmful alcohol use were verified, indicating vulnerabilities that must be properly monitored and treated to reduce emotional suffering in this population.
