The oral health impact profile and well-being on mothers and preschool children.

OBJECTIVES: to verify the contribution of mothers' oral health impact profile to their children's oral health profile and the contribution of mothers' well-being and the caries index (dmft) to children's well-being. METHODS: This is a cross-sectional observational study. Mothers and pre-school children enrolled in public schools in the municipality of Araraquara-SP took part. The Oral Health Impact Profile Questionnaire (OHIP-14), Satisfaction with Life Scale (SWLS), Early Childhood Oral Health Impact Scale (ECOHIS) and the Autoquestionnaire Qualité de Vie Enfant Imagé (AUQEI) were used. To diagnose caries, a clinical examination was carried out to calculate the dmft index. Path analysis was carried out and the path coefficients were estimated (ß) and evaluated using the z-test (α = 5%). RESULTS: 443 children took part (5.19 ± 0.64 years; 52.4% boys) with an mean dmft of 1.31 ± 2.19. The mean age of the mothers was 33.4 ± 7.01 years. There was a significant impact of dmft and maternal well-being on the child's subjective well-being (s2explained = 43%). The mothers' oral health impact profile and the child's caries experience had a significant influence on both the child (OHIP: ß = 0.22; p < 0.001; dmft: ß = 0.48; p < 0.001) and the family (OHIP: ß = 0.29; p < 0.001; dmft: ß = 0.32; p < 0.001). The child's dmft (ß=-0.10; p = 0.005) and the mothers' subjective well-being (ß=-0.61; p < 0.001) had a significant impact on the child's subjective well-being. CONCLUSION: The mothers' oral health impact profile and the child's caries experience had an impact on both the child and the family. Mothers' subjective well-being and caries experience should be considered when assessing the subjective well-being of Brazilian preschool children.

Social Appearance Anxiety Scale: a psychometric investigation and evaluation of the influence of individual characteristics on social appearance anxiety in Brazilian adults who practice physical exercise.

Introduction: Evaluating signs of anxiety related to body appearance is becoming increasingly important in contemporary society and, in this sense, the Social Appearance Anxiety Scale (SAAS) seems an interesting alternative of measurement. Objectives: To evaluate the psychometric properties of the Portuguese version of the SAAS when applied to Brazilian adults who practice physical exercise and verify the influence of individual characteristics on participants' social appearance anxiety. Methods: This was a cross-sectional study conducted online. The participants completed the SAAS and a demographic questionnaire. The psychometric properties of the SAAS one-factor model were evaluated using confirmatory factor analysis. A structural model was built for men and women to verify the influence of individual characteristics of the participants on social appearance anxiety. Results: 1,495 individuals participated in the study (70.8% women; mean age = 29.5, SD = 8.9 years). The data obtained with the SAAS presented good indicators of validity and reliability for both genders (CFI > 0.97, TLI > 0.97, SRMR = 0.04, α > 0.97, ω > 0.85). For both men and women, greater levels of social appearance anxiety were observed among younger participants, who had a higher body mass index, self-reported an eating disorder, and perceived a change in their body after the onset of the COVID-19 pandemic. For women specifically, higher income and having started physical exercise more recently were associated with greater levels of social appearance anxiety. Conclusion: The findings supported the validity and reliability of the data obtained with the SAAS and revealed that when investigating social appearance anxiety in future research and clinical protocols, specific individual characteristics should be considered.

Aesthetic dental treatment, orofacial appearance, and life satisfaction of Finnish and Brazilian adults.

AIMS: To study the probability of seeking/undergoing aesthetic dental treatment (ADT) and compare self-perception of orofacial appearance (OA) based on sex, age, and monthly income; and to estimate the impact of OA on life satisfaction (LS) among Finnish and Brazilian adults, considering the indirect effect of receiving ADT and the moderating effects of those sociodemographic variables. METHODS: This was an online cross-sectional study. Orofacial Esthetic Scale (OES), Psychosocial Impact of Dental Aesthetics Questionnaire (PIDAQ) and Satisfaction with Life Scale (SWLS) were used. Probability of seeking/receiving ADT was calculated using logistic regression and odds ratio (OR). OA scores were compared according to sociodemographic characteristics (ANOVA, α = 5%). Structural equations models estimated the impact of OA on LS. RESULTS: 3,614 Finns [75.1% female, 32.0 (SD = 11.6) years] and 3,979 Brazilians [69.9% female, 33.0 (SD = 11.3) years] participated in the study. Women were more likely to receive ADT than men in both countries (OR>1.3). However, no statistically or practical significant differences were observed in OA between sexes (p>0.05 or p<0.05, ηp2 = 0.00-0.02). In Finland, demand for ADT (OR = 0.9-1.0) and OA scores (p>0.05) were the same among different ages and monthly income. In Brazil, younger individuals (OR>1.6) and those with higher monthly income (OR>2.7) were more likely to receive ADT, while those with lower income had a greater psychosocial impact of OA (p<0.05; ηp2>0.07). Individuals who were more satisfied with their own OA and had less psychosocial impact from OA had higher levels of LS (ß = 0.31-0.34; p<0.01; explained variance: 9.8-13.1%). CONCLUSION: Demand for ADT is influenced by sociodemographic and cultural factors. Greater societal pressure on physical appearance is observed among women in Western countries. In countries with high socioeconomic inequalities, consumerism and social prestige are involved in this demand. Self-perception of orofacial appearance plays a significant role in individuals' subjective well-being. Therefore, the planning of aesthetic treatments in the orofacial region should consider the patient's perceptions and social context.

Subjective wellbeing of preschool children.

Objective: The aim of the present study was to evaluate the psychometric properties of the Autoquestionnaire Qualité de Vie Enfant Imagé (AUQEI) in pre-school children and estimate the influence of demographic characteristics on their subjective wellbeing. Methods: Construct validity was estimated using confirmatory analysis and the chi-square per degrees of freedom ratio (χ2/df), Comparative Fit Index (CFI), Tucker-Lewis Index (TLI), and Root Mean Square Error of Approximation (RMSEA). Reliability was assessed by the ordinal alpha (α) and omega (ω) coefficients and the factorial invariance by the difference in CFI (ΔCFI). Mean scores for each AUQEI item and the general score were calculated. Results: A total of 443 Preschool children enrolled in public education institutions participated. The original 4-factor AUQEI model showed collinearity between factors and a high correlation between two items. A single factor model was tested, presenting adequate fit to the data (χ2/df = 4.47; CFI = 0.98; TLI = 0.98; RMSEA = 0.08; α = 0.98; ω = 0.93; UniCo > 0.95, EVC > 0.85, and MIREAL < 0.30) and strict model invariance (ΔCFI < 0.01). The AUQEI model proved to be valid in relation to the external variables. Most children (76.7%) had positive subjective wellbeing. Higher scores were observed for items concerning recreation, holidays, and birthdays, and lower scores for those referring to hospitalization, medication, medical consultation, and being away from the family. The relationship between the demographic characteristics of the child or his/her mother and subjective wellbeing was not significant (p > 0.05). Conclusions: The assessment of subjective wellbeing with the single-factor AUQEI model provided valid, reliable, and invariant. Thus, being a relevant and interesting instrument to assess wellbeing in young children.

Handgrip force and bite force in dentulous and edentulous individuals.

BACKGROUND: The literature is unclear about bite force (BF) and handgrip force (HF) in a specific group of different ages and dentate conditions, or even a predictive model for each specific group, using BF and HF as factors. OBJECTIVE: To establish the correlation between HF and BF in female participants with distinct ages and dentate conditions; also create a predictive model of BF as a function of HF. METHODS: Participants were divided into three groups (GI: young natural dentate women, n = 65; GII: adult natural dentate women, n = 67; and GIII: edentulous women users of bimaxillary complete dentures, n = 67) and subjected to an HF measurement test using a digital dynamometer. Subsequently, BF was measured using a digital gnathodynamometer in the molar region. Pearson correlation coefficient (r) and multivariate analysis of variance (α = 0.05) were performed, and simple linear regression was used to obtain a model to predict BF from HF for each group separately (α = 0.05). RESULTS: All groups presented moderate and strong correlations among the variables (GI: r = 0.838; GII: r = 0.714; GIII: r = 0.646). A significant difference in BF was observed (GI > GII > GIII; p < .05). GIII presented a significantly lower HF than the other groups (p < .05). Besides, three equations predicting BF, using HF, were obtained for use in young/adult dentate and edentulous women. CONCLUSION: All groups found a positive and significant correlation between BF, HF and groups. HF can be a simple and efficient method for predicting BF using the predictive models developed for women with good health.

COVID-19 pandemic: Prevalence of depression, anxiety, and stress symptoms among Brazilian psychologists.

Introduction: Symptoms related to mental health disorders became the background of the COVID-19 pandemic, and psychologists had to adapt to the demands, while they themselves were exposed to the pandemic and its stressors. Objectives: To identify demographic and professional characteristics of Brazilian psychologists in different phases of pandemic and their reported care practices, concerns, and symptoms. Methods: This was an observational study conducted online in four independent phases with no pairing among the samples (May/June 2020, n = 263; November/December 2020, n = 131; May/June 2021, n = 378; November/December 2021, n = 222). Depression, Anxiety and Stress Scale was used. The validity and reliability of the data obtained with the DASS-21 were attested to by confirmatory factor analysis. Basic lexographic and similarity analysis were conducted to obtain textual information. Prevalence of variables was estimated and compared between phases using the z-test (α = 5%). Similarity analysis was performed to identify the psychologists' concerns. Results: Most of participants were women and were self-employed or employed. There was rapid adjustment to remote work and more than 70% reported changes in their mental health since the onset of pandemic. One in four participants had a previous mental health disorder, and there was a high prevalence of symptoms such as anxiety, fear, and angst. The prevalence of professionals who reported not caring about their own mental health was significant. In 2020, one cluster (health) of concern was identified, while in 2021 there were three clusters (health, family, and COVID-19). The prevalence of depression, anxiety, and stress symptoms was high and did not change during the pandemic. Conclusions: Psychologists adapted to the demands of the population in the face of the pandemic. However, there was a high prevalence of mental health symptoms and a disregard for self-care among these professionals.

Exercise motives among university students - A Brazil-Portugal transnational study.

Background: Identifying the motives why people exercise is interesting for the planning of effective health promoting strategies. Objectives: To estimate the psychometric properties of the exercise motivations inventory (EMI-2) in Brazilian and Portuguese university students, and to compare motive-related factors for exercise among students. Methods: One thousand Brazilian (randomly splitted into "Test sample" [n = 498] and "Validation sample" [n = 502]) and 319 Portuguese students participated in this cross-sectional study. Motives for exercise were evaluated using EMI-2. Exploratory factor analysis was performed in the test sample. Then, confirmatory factor analysis was performed in the validation and Portuguese samples. The EMI-2 scores were compared according to sex, exercise, and weight status (ANOVA, α = 5%). Results: EMI-2 factor model was explained by 5 factors and presented adequate fit (χ 2/df ≤ 3.2; CFI ≥ 0.9; TLI ≥ 0.9; RMSEA ≤ 0.07; and α ≥ 0.83). The motives for exercising were mainly related to psychological and interpersonal factors for men, health-related factors for women, and body-related factors for overweight and obese individuals. People who practice exercise had higher EMI-2 scores. Conclusion: The 5-factor model is suggested for a comprehensive assessment of motives for exercise. Individual characteristics should be considered for development of tailored protocols.

Relationship between Attention to Body Shape, Social Physique Anxiety, and Personal Characteristics of Brazilians: A Structural Equation Model.

People can develop eating disorders due to excessive body image concerns. The primary objective of this study was to examine the relationship between attention to body shape, social physique anxiety, and personal characteristics in a sample of Brazilians. The secondary objective was to evaluate the correlation of the constructs with the participants' body composition. First, 1795 individuals (70% female; Mage = 25.5 ± 6.6 years) completed the Attention to Body Shape Scale, the Social Physique Anxiety Scale, and a sociodemographic questionnaire. Then, 286 participants (58% female; Mage = 25.3 ± 5.7 years) underwent a bioimpedance exam to identify body composition. Structural equation modeling was used to estimate the relationship between the variables. The greater the attention to body shape, the greater the expectations of negative physical evaluation and the less comfort with physical presentation. Younger age, female gender, consumption of supplements/substances for body change, restrictive diets, physical inactivity, poor self-assessment of food quality, and overweight/obesity were related to negative body concerns. An expectation of negative physical evaluation was positively correlated with body fat and negatively with muscle mass. Comfort with physical presentation was negatively correlated with fat and positively with muscle. These results can support preventive strategies aimed at reducing eating disorders resulting from body image concerns.

Impact of body and orofacial appearance on life satisfaction among Brazilian adults.

AIMS: 1. to elaborate a general model of physical appearance taking into account body image (BI) and orofacial appearance (OA) components; and 2. to evaluate the impact of BI and OA on life satisfaction among Brazilian adults. METHODS: This is a cross-sectional observational study. The cognitive, behavioral, affective, and satisfaction/dissatisfaction aspects of BI, the satisfaction and psychosocial impact of OA, and life satisfaction were evaluated by self-reported psychometric scales. Principal Component Analysis and Parallel Analysis were performed. Structural equation models were elaborated to estimate the impact of BI and OA on life satisfaction. The fit of the models was verified and the significance of the path estimates (ß) was evaluated using z-tests (α = 5%). RESULTS: A total of 1,940 individuals participated in the study (age: mean = 24.8, standard deviation = 5.7 years; females = 70.1%). In the male sample, three physical appearance factors were retained (OA, cognitive and behavioral components of BI, and affective and satisfaction/dissatisfaction components of BI). In the female sample, two factors were retained (OA and all components of BI). All factors had significant impact on life satisfaction (ß = |0.26|-|0.48|, p<0.001) in both samples. Individuals dissatisfied with BI and OA had lower levels of life satisfaction. For men, the affective and satisfaction components of BI had a greater impact on life satisfaction (ß = 0.48, p<0.001) than the other factors (ß =] -0.30;-0.25[, p<0.001). For women, both BI and OA had a similar impact (BI: ß = -0.30, p<0.001; OA: ß = -0.32, p<0.001). CONCLUSION: BI and OA formed distinct clusters in the physical appearance evaluation. Physical appearance was perceived differently by men and women, fostering discussion about the sociocultural construction of the body. BI and OA had a significant impact on life satisfaction and should be considered in assessment and treatment protocols.

Investigating method effects associated with the wording direction of items of the Social Physique Anxiety Scale.

PURPOSE: The use of psychometric instruments to measure latent concepts is common. The development of these instruments usually involves mechanisms to reduce response bias, such as the inclusion of reversed items. The aim of this study was to investigate method effects related to the wording direction of the Social Physique Anxiety Scale (SPAS) items, a one-dimensional instrument that assesses individual's level of anxiety when others observe their body. METHODS: In total, 152 Brazilian adults (65.8% female) answered 2 formats of the SPAS: the original with 12 items (7 regular and 5 reversed); and a new format with all items written in the same direction (i.e., regular). Both formats were filled out at different times and alternately. Differential item functioning analysis (DIF) and confirmatory factor analysis were conducted. RESULTS: The original SPAS did not fit the data, but after allowing covariances between all reversed items, the fit improved. The wording effect was supported by the DIF, indicating a better fit to the data for the new format with all items worded in the same direction. CONCLUSION: The wording of the SPAS items had effect on the psychometric properties of instrument. When the wording of the reversed items was modified, the factor model fitted the data. Future studies should take these findings into account and evaluate the SPAS with all items worded in the same direction in different contexts. LEVEL OF EVIDENCE: Descriptive (cross-sectional) study, Level V.

Authentic Leadership Questionnaire applied to Brazilian nurses: evidence of validity. / Authentic Leadership Questionnaire aplicado a enfermeiros brasileiros: evidências de validade.

OBJECTIVE: to establish the psychometric properties of the Authentic Leadership Questionnaire (ALQ) applied to Brazilian nurses. METHOD: cross-sectional observational study with a non-probabilistic sample. The psychometric properties of the RATER and SELF versions of the ALQ were calculated using confirmatory factor analysis with the WLSMV robust estimation method. The following indices were used to assess the goodness-of-fit of the model: chi-square by degrees of freedom (χ2/df), Tucker-Lewis Index (TLI), Comparative Fit Index (CFI), Root Mean Square Error of Approximation (RMSEA) and Standardized Root Mean Squared Residual (SRMR). Data reliability was analyzed using the ordinal coefficient alpha and composite reliability. RESULTS: 181 nurses participated of the study (female gender: 80.1%; mean age of 34.6 years; working time of less than five years: 76.3%). The complete ALQ RATER and ALQ SELF models did not present an adequate fit. Therefore, the refined models presented a better fit to the sample data (ALQ RATER: χ2/df=2.77; CFI=0.97; TLI=0.97; RMSEA=0.10; SRMR=0.05; ALQ SELF: χ2/df=2.74; CFI=0.94; TLI=0.92; RMSEA=0.10; SRMR=0.08). In the ALQ RATER model, items 1, 7 and 13 were excluded. Due to the high correlation between the factors Relational Transparency and Moral Perspective, a three-factor model based on the combination of the factors mentioned above was proposed. In the ALQ SELF model, items 2, 5, 9 and 10 were excluded. Likewise, a three-factor model based on the combination of two factors, now called Self-Awareness Balance, was proposed. CONCLUSION: the data obtained with the Authentic Leadership Questionnaire with Brazilian nurses were valid and reliable.

Coping Strategies and Their Relationship With Subjective Distress due to the COVID-19 Pandemic in Brazil.

OBJECTIVES: To identify the strategies used by Brazilian adults for coping with the COVID-19 pandemic and to verify the effect of these strategies on subjective distress. METHODS: This was a cross-sectional observational study with online data collection in May/June 2020, November/December 2020, and May/June 2021. The BriefCOPE Inventory and the Impact of Event Scale (IES-R) were used. The prevalence of strategies used at different time points was estimated with a 95% confidence interval and compared with a z-test. A multiple logistic regression model was constructed and the odds ratio (OR, 95%CI) was calculated to verify the probability of subjective distress according to the coping strategy used. RESULTS: Younger individuals had a lower prevalence of adaptive strategies, which increased significantly with age. Participants with higher income levels had a higher prevalence of adaptive strategies, as did those who were never diagnosed with a mental health disorder. The prevalence of using only maladaptive strategies ranged from 6.1% to 5.4% (p > 0.05). The use of problem-centered strategies (Active Coping and Planning), venting of emotions, and substance use increased with time, while acceptance and behavioral disengagement decreased. In general, the population used problem-centered strategies, but the high prevalence of problem avoidance was striking. Positive reinterpretation and acceptance were protective factors for subjective distress, whereas maladaptive strategies increased the chance of distress. The presence of a negative valence component (problem- or emotion-centered) increased the chance of subjective distress, whereas strategies based on Problem Solving acted as a protective factor. CONCLUSION: Coping strategies were significantly associated to subjective distress and have changed since the beginning of the pandemic. Strategies focused on emotion regulation may be relevant to minimize distress.

Self-perception of orofacial appearance: Brazil-Finland cross-national study.

OBJECTIVE: (i) To study the measurement invariance of Orofacial Esthetic Scale (OES) and Psychosocial Impact of Dental Aesthetics Questionnaire (PIDAQ), (ii) to compare the perception of orofacial appearance (OA) and (iii) to study the frequency of individuals who have sought or received aesthetic dental treatment between Brazil and Finland. METHODS: This was a cross-sectional observational study with snowball non-probability sample selection. Students and staff from universities in Finland and Brazil were invited to participate. Data were collected online using a demographic questionnaire, OES and PIDAQ. The samples consisted of 3636 Finns (75.0% female; age: 32.0 years) and 1468 Brazilians (72.6% female; age: 33.2 years). The frequency of receiving aesthetic dental treatment was estimated. If configurational invariance was observed, cross-national measurement invariance was verified by multigroup analysis. When measurement invariance was attested, factor scores were compared using Welch's t-test. RESULTS: OES showed configurational and measurement invariance and no significant difference between the countries. Despite similarity in satisfaction with OA, 71.9% of Brazilians had received aesthetic dental treatment, while 59.4% of Finns had never sought such treatments. PIDAQ did not present configurational invariance between the countries. CONCLUSION: Although there is no difference in satisfaction with OA, seeking and receiving aesthetic dental treatment is significantly greater for Brazilians. Psychosocial impact of OA is perceived differently in the studied countries.

Psychometric investigation of the Attention to Body Shape Scale in Brazilian adults.

The objectives of the study were to develop a Portuguese version of Attention to Body Shape Scale (ABS), estimate the psychometric properties of the ABS for Brazilian data, and compare the ABS scores between the sexes and the different sample characteristics. The Portuguese version was developed following a standardized protocol. The factorial and convergent validity were evaluated using goodness-of-fit parameters and average variance extracted. Composite reliability and ordinal coefficient alpha were calculated. The invariance of the fitted model was investigated across independent subsamples using multigroup analysis. The scores were compared between variables using two-way ANOVA. A total of 1,056 individuals (71% female) with a mean age of 26.1 (SD=6.4) years participated in the study. Item 3 was removed due to low factor loading. The refined model presented good psychometric properties for the data. Different characteristics contributed to greater attention to body shape. The Portuguese version of the ABS will be useful to investigate attention to body shape in Brazil. The validity and reliability of the data supported the adequacy of the refined model. Specific characteristics influenced attention to body shape, and therefore, should be considered in future protocols.

Effect of magnification factor by Galilean loupes on working posture of dental students in simulated clinical procedures: associations between direct and observational measurements.

Objectives: To determine the effect of different levels of Galilean loupe magnification on working posture as measured by compliance with ergonomic posture positions, angular deviation from the neutral position of the neck, and muscle activation in the neck and upper back region during simulated clinical conditions. Methods: An experimental laboratory study was performed in which the dependent variables were compliance with ergonomic posture requirements while performing simulated restorative procedures in Restorative Dentistry, angular deviation from the neutral position of the neck, and muscle activation in the neck and upper back. The independent variable was the level of Galilean loupe magnification, which was tested at four levels (naked eye, 2.5× magnification, 3.0× magnification, and 3.5× magnification). The cavity preparations and Class I composite resin restorations were performed on artificial first molars on a mannequin in a dental chair. The Compliance Assessment of Dental Ergonomic Posture Requirements (CADEP) was used for the postural analysis; as was an analysis of the angular deviation from the neutral position of the neck and surface electromyography. Working posture was recorded on video over the course of the procedure. Participants were filmed from three different angles. The Compliance Assessment of Dental Ergonomic Posture Requirements (CADEP) assessed compliance with ergonomic posture requirements. A locally produced posture assessment software analyzed angular deviation. Surface electromyography bilaterally assessed activation of the sternocleidomastoid, descending trapezius and ascending trapezius muscles. Two-factor analysis of variance (ANOVA) and either Tukey's post-hoc test or the Games-Howell post-hoc test were performed (α = 0.05). Results: During the cavity preparations and restorations, the use of Galilean loupes at all magnifications positively influenced working posture as measured by participants' compliance with ergonomic posture positions (p < 0.01) and neck angulation (p < 0.01); the use of these loupes did not affect muscle activation in the regions evaluated (p > 0.05). Conclusion: The use of Galilean loupes had a positive effect on dental students' working posture during the restoration procedures performed.

Cross-cultural adaptation and psychometric assessment of the Portuguese language version of the Eating and Appraisal due to Emotions and Stress (EADES) Questionnaire in Brazilian adults.

PURPOSES: To develop a Brazilian Portuguese version of the Eating and Appraisal due to Emotions and Stress (EADES) Questionnaire and estimate the psychometric properties of the EADES factorial model for young Brazilian adults and also to assess the association between EADES factors and age, body mass index (BMI), and economic level. METHODS: The cross-cultural adaptation was performed using a standardized protocol. The psychometric properties were assessed separately for each sex. A structural model for each sex was developed to investigate the influence of age, economic level, and BMI on the EADES factors. RESULTS: A total of 1240 participants completed the study [65.8% female, mean age 23.91 (SD = 5.03) years]. The EADES original factorial model did not present good psychometric properties. Then, a factorial model proposed for a Mexican sample was tested and a different model was fitted for each sex. The results showed that younger women have lower self-efficacy and self-confidence and poorer assessment of resources and coping skills. Women with a higher economic level have lower self-efficacy. Higher BMI was associated with lower self-efficacy and self-confidence in both sexes. Younger men have lower self-efficacy and poorer assessment of resources and coping skills. CONCLUSIONS: The Brazilian Portuguese version of the EADES provided valid and reliable data after refinement, and a different model was fitted for each sex. Sex, age, BMI, and economic level were significantly associated with the EADES factors. LEVEL OF EVIDENCE: Level V, descriptive cross-sectional study.

The Psychological Impact of COVID-19 on Individuals With and Without Mental Health Disorders.

OBJECTIVE: To identify people with history of mental health disorders before the COVID-19 pandemic in the Brazilian population and estimate the prevalence of mood swings and the subjective distress of the pandemic among individuals with or without mental health disorders. METHODS: Through an online survey, participants were asked about presence or absence of mental health disorders. In addition, they answered the Brunel Mood Scale and the Impact of Event Scale. The mean percentile of mood swing indicators and psychological impact scores were estimated, and data were analyzed by logistic regression. RESULTS: 13,248 people participated (70.5% women, mean age 35.4 years, 31.2% with history of mental health disorder). Women and younger people were more likely to be diagnosed with mental health disorder. All participants had significant changes in mood due to the pandemic. Anger, depressed mood, mental confusion, and fatigue were higher among individuals with bipolar disorder or with combined disorders. Individuals with mental health disorders had a greater subjective distress, especially the group with bipolar disorder (OR = 4.89 [3.64-6.56]) and combined disorders (OR = 6.89 [5.21-9.10]). CONCLUSION: Individuals previously diagnosed with mental health disorders at some point in life are more vulnerable to psychological impact from the pandemic.

Authentic Leadership Questionnaire aplicado a enfermeiros brasileiros: evidências de validade / Authentic Leadership Questionnaire applied to Brazilian nurses: evidence of validity / Authentic Leadership Questionnaire aplicado a enfermeros brasileños: evidencias de validez

Resumo Objetivo: estimar as propriedades psicométricas do Authentic Leadership Questionnaire (ALQ) aplicado a enfermeiros brasileiros. Método: estudo observacional transversal com amostragem não probabilística. As propriedades psicométricas das versões RATER e SELF do ALQ foram estimadas utilizando-se análise fatorial confirmatória com método de estimação robusto WLSMV. Como índices de qualidade de ajustamento dos modelos, foram utilizados: razão do qui-quadrado pelos graus de liberdade (χ2/gl), Tucker-Lewis Index (TLI), Comparative Fit Index (CFI), Root Mean Square Error of Aproximation (RMSEA) e Standardized Root Mean Squared Residual (SRMR). A confiabilidade dos dados foi analisada por meio do coeficiente alfa ordinal e da confiabilidade composta. Resultados: participaram 181 enfermeiros (sexo feminino: 80,1%; média de idade de 34,6 anos; tempo de trabalho inferior a cinco anos: 76,3%). Os modelos completos da ALQ RATER e ALQ SELF não apresentaram ajustamento adequado. Porquanto, o modelo refinado apresentou melhor ajustamento para a amostra (ALQ RATER: χ2/gl=2,77; CFI=0,97; TLI=0,97; RMSEA=0,10; SRMR=0,05; ALQ SELF: χ2/gl=2,74; CFI=0,94; TLI=0,92; RMSEA=0,10; SRMR=0,08). No modelo ALQ RATER, foram removidos os itens 1, 7 e 13. Devido à alta correlação entre os fatores Transparência Relacional e Perspectiva Moral, foi proposto um modelo trifatorial com base na junção dos fatores acima citados. No modelo ALQ SELF, foram retirados os itens 2, 5, 9 e 10. Do mesmo modo, foi proposto um modelo trifatorial baseado na junção de dois fatores agora denominado Equilíbrio Autoconsciência. Conclusão: os dados obtidos com Authentic Leadership Questionnaire com enfermeiros brasileiros foram válidos e confiáveis.

Abstract Objective: to establish the psychometric properties of the Authentic Leadership Questionnaire (ALQ) applied to Brazilian nurses. Method: cross-sectional observational study with a non-probabilistic sample. The psychometric properties of the RATER and SELF versions of the ALQ were calculated using confirmatory factor analysis with the WLSMV robust estimation method. The following indices were used to assess the goodness-of-fit of the model: chi-square by degrees of freedom (χ2/df), Tucker-Lewis Index (TLI), Comparative Fit Index (CFI), Root Mean Square Error of Approximation (RMSEA) and Standardized Root Mean Squared Residual (SRMR). Data reliability was analyzed using the ordinal coefficient alpha and composite reliability. Results: 181 nurses participated of the study (female gender: 80.1%; mean age of 34.6 years; working time of less than five years: 76.3%). The complete ALQ RATER and ALQ SELF models did not present an adequate fit. Therefore, the refined models presented a better fit to the sample data (ALQ RATER: χ2/df=2.77; CFI=0.97; TLI=0.97; RMSEA=0.10; SRMR=0.05; ALQ SELF: χ2/df=2.74; CFI=0.94; TLI=0.92; RMSEA=0.10; SRMR=0.08). In the ALQ RATER model, items 1, 7 and 13 were excluded. Due to the high correlation between the factors Relational Transparency and Moral Perspective, a three-factor model based on the combination of the factors mentioned above was proposed. In the ALQ SELF model, items 2, 5, 9 and 10 were excluded. Likewise, a three-factor model based on the combination of two factors, now called Self-Awareness Balance, was proposed. Conclusion: the data obtained with the Authentic Leadership Questionnaire with Brazilian nurses were valid and reliable.

Resumen Objetivo: estimar las propiedades psicométricas del Authentic Leadership Questionnaire (ALQ) aplicado a enfermeros brasileños. Método: estudio observacional transversal con muestreo no probabilístico. Las propiedades psicométricas de las versiones RATER y SELF del ALQ se estimaron mediante análisis factorial confirmatorio con el método de estimación robusta WLSMV. Como índices de calidad de ajuste de los modelos se utilizó: razón de chi-cuadrado por grados de libertad (χ2/gl), Tucker-Lewis Index (TLI), Comparative Fit Index (CFI), Root Mean Square Error of Approximation (RMSEA) y Standardized Root Mean Squared Residual (SRMR). La confiabilidad de los datos se analizó mediante el coeficiente alfa ordinal y la confiabilidad compuesta. Resultados: participaron 181 enfermeros (sexo femenino: 80,1%; edad media de 34,6 años; tiempo de trabajo inferior a cinco años: 76,3%). Los modelos completos ALQ RATER y ALQ SELF no mostraron un ajuste adecuado. Por lo tanto, el modelo refinado presentó un mejor ajuste para la muestra (ALQ RATER: χ2/gl=2,77; CFI=0,97; TLI=0,97; RMSEA=0,10; SRMR=0,05; ALQ SELF: χ2/gl=2,74; CFI=0,94, TLI=0,92, RMSEA=0,10, SRMR=0,08). En el modelo ALQ RATER se eliminaron los ítems 1, 7 y 13. Debido a la alta correlación entre los factores Transparencia Relacional y Perspectiva Moral, se propuso un modelo de tres factores basado en la unión de los factores mencionados anteriormente. En el modelo ALQ SELF se eliminaron los ítems 2, 5, 9 y 10. Asimismo, se propuso un modelo trifactorial basado en la unión de dos factores, ahora denominado Equilibrio de Autoconciencia. Conclusión: los datos obtenidos con el Authentic Leadership Questionnaire con enfermeros brasileños fueron válidos y confiables.
