- ItemAcesso aberto (Open Access)Autoavaliação do comportamento comunicativo de líderes de diversas profissões ao falar em público(Universidade Federal de São Paulo (UNIFESP), 2017-02-24) Vargas, Aline Cristina Tafarelo [UNIFESP]; Behlau, Mara Suzana [UNIFESP]; http://lattes.cnpq.br/2274436726620746; http://lattes.cnpq.br/8622071356562346; Universidade Federal de São Paulo (UNIFESP)Objective: Understanding how corporate leaders evaluate themselves in situations of public speaking, taking into consideration specific aspects of speech, voice and manifestations of nervousness and anxiety. Methods: Three hundred and twenty-eight individuals participated in this study, being 143 men and 185 women, having corporate leadership positions in various segments, mean age of 41 years old. Three evaluation instruments were applied: a Communication Contexts Questionaire CCQ-R reduced from Questionnaire of Self-Evaluation on Speech and Voice Abilities in Various Communication Contexts – QCC, with 23 questions, the Self-Statements during Public Speaking Scale - SSPS, with 10 questions and the Voice Handicap Index 10 – VHI-10, also with 10 questions. The results were evaluated according to sex and age. Results: Speaking in meetings was the most referred experience of speaking in public (88.4). The participants indicated perceived modifications in the aspects of speech, voice, nervousness and anxiety, with different distribution in relation to sex and age. Perceiving that the speech and voice become different on speaking in public is the most pointed symptom (50.3% and 78.5%, respectively). The majority of leaders feel nervous in this situation (84.4%), being the insecurity about the context the factor which generates more nervousness (69.0%). The majority of the leaders also feel anxious when speaking in public (83.3%), showing the symptom of sweating on the hands (31.3%). Despite the negative manifestations in the researched aspects, the leaders evaluated themselves positively in the situation of speaking in public, according to SSPS. There are fewer occurrences of negative manifestations in speech, voice, nervousness and anxiety in older participants, which can suggest that a positive effect of the experience and the informal learning on this practice. A high percentage of leaders, 14.7%, perceived some vocal disadvantage according to the VHI-10. Conclusion: For the majority of leaders, speaking in public pose a challenge, which can generate negative impacts in communication. Positions of leadership evaluate their communication on speaking in public as good, although they recognize the occurrence of various deviations in speech and voice, including manifestations of nervousness and anxiety in this situation. For both sexes, aging seems to have a positive effect in public speaking situations.
- ItemSomente MetadadadosEfficiency and Cutoff Values of Self-Assessment Instruments on the Impact of a Voice Problem(Mosby-Elsevier, 2016) Behlau, Mara; Madazio, Glaucya; Moreti, Felipe [UNIFESP]; Oliveira, Gisele; Alves dos Santos, Luciana de Moraes; Paulinelli, Bruna Rabelo; Couto Junior, Euro de BarrosObjectives. To evaluate the efficiency of four self-assessment questionnaires that rate the impact of a voice problem on the individual's life: Voice-Related Quality of Life (V-RQOL), the original and reduced versions of the Voice Handicap Index (VHI) and VHI-10, Vocal Performance Questionnaire (VPQ), and Voice Symptom Scale (VoiSS). Methods. Data from 975 subjects, 486 with a diagnosis of dysphonia and 489 vocally healthy individuals, were submitted to the receiver operating characteristic (ROC) curve analysis to obtain the cutoff values that determine the discriminating power of these instruments (presence of dysphonia vs healthy voice). Results. The ROC curve analysis showed that the most efficient questionnaires were the VoiSS and the VHI. Results showed that they presented as a perfect classification based on their efficiency, specificity, and sensitivity values (all three of them = 1). The VHI-10 and the V-RQOL showed excellent classification (VHI-10: efficiency = 0.991
- ItemAcesso aberto (Open Access)Influência de alterações do sono na qualidade vocal(Universidade Federal de São Paulo (UNIFESP), 2017-02-24) Rocha, Bruna Rainho [UNIFESP]; Behlau, Mara Suzana [UNIFESP]; http://lattes.cnpq.br/2274436726620746; http://lattes.cnpq.br/7664517668044679; Universidade Federal de São Paulo (UNIFESP)Objectives: To verify the influence of the sleep quality on the voice. Methods: Self-assessment of the vocal quality, sleep pattern and related data, were collected by an on-line or printed survey. The survey was divided in 3 parts: 1. Demographic data and vocal health aspects, 2. Self-assessment of sleep and vocal quality and the influence that sleep has on voice, 3. Sleep and voice self-assessment tools, which included the Epworth Sleepiness Scale - ESS, Pittsburgh Sleep Quality Index - PSQI and Voice Handicap Index reduced version – VHI-10. 862 people were included (493 women; 369 men), with a mean age of 32 years old (maximum age of 79 years and minimum of 18). Results: The perception of the influence that sleep has on voice showed difference (p<0.050) between sleep and voice self-assessment. In other words, if sleep was self-rated as poor, the voice was also self-rated as bad for individuals who perceived the influence of sleep on voice. There is more risk of presenting alteration on the ESS, PSQI and VHI-10 protocols if sleep and vocal self-assessment are worst, what shows the influence that self-assessment has on the results of these specific tools. The influence of sleep on voice impacts only the VHI-10 score: the greater the perception of this influence, the larger the perceived vocal disadvantage. Sex was not a determinant factor on the outcome regarding the self-assessment instruments. A total of 73 individuals (8.5%) presented deviations for all protocols: ESS, PSQI and VHI-10, while 134 subjects (15.5%) had no deviation for anyone of them. No relationship was found for presence of snoring and vocal quality. The aspects that influence a vocal disadvantage are: voice self-assessment, ESS total score and self-assessment of the influence that sleep has on voice. The absence of daytime sleepiness is a protective factor (OR>1) against vocal disadvantage, meanwhile the presence of daytime somnolence is a damaging factor (OR<1). Conclusion: The sleep quality influences the vocal quality. A bad sleep quality is related to a bad vocal quality. Individuals with vocal disadvantages perceive a greater influence of sleep on voice; the variables that influence these vocal disadvantages are vocal self-assessment, ESS total score, and self-assessment that sleep has on voice. Individuals with daytime somnolence are more likely to have a vocal disadvantage.
- ItemAcesso aberto (Open Access)Qualidade vocal e processamento auditivo em indivíduos com e sem prática musical(Universidade Federal de São Paulo (UNIFESP), 2017-06-29) Paoliello, Karla Barbosa Guarda [UNIFESP]; Behlau, Mara Suzana [UNIFESP]; Pereira, Liliane Desgualdo [UNIFESP]; http://lattes.cnpq.br/0546134611213515; http://lattes.cnpq.br/2274436726620746; http://lattes.cnpq.br/0801816123717692; Universidade Federal de São Paulo (UNIFESP)INTRODUCTION: The relationship between voice and auditory processing is complex and has aroused greater scientific interest in the last decades. However, little is known about the relationship between vocal quality and auditory processing in individuals with and without musical practice. OBJECTIVES: To verify the vocal quality and the physiological mechanisms of selective attention and temporal ordering in individuals with and without musical practice. METHODS: 136 individuals were divided into three groups: G1 = singers, G2 = instrumentalists and G3 = without musical practice, non-singers and non-instrumentalists; The G1 group was subdivided into G1.1 = instrumentalist singers and G1.2 = singers only. The subjects underwent vocal evaluation through auditory perceptual analysis (APA) of the recording of their spoken voices, categorizing them and self - assessment of a possible voice problem through the Vocal Symptom Scale - VoiSS. The participants had their central auditory processing evaluated by the following tests: Pattern Frequency Test (FPT), Random Gap Detection Test (RGDT), Staggered Spondaic World (SSW), Speech in Noise and Synthetic Sentence Identification (SSI). The correlation between voice and auditory abilities was studied. RESULTS: The majority of individuals in all the groups studied did not present vocal deviation, which when it occurred was of a discrete degree; (G1.1 = 46.15% and G2 = 18.18%) and 1 (G1.1 = 46.15% and G2 = 75%). There was no statistically significant association between the various APA levels and the sexes evaluated. G1 reported more vocal symptoms than the other groups with averages above 16 points in the ESV, with G1.2 presenting a mean of 23.86 and G1.1 of 21.70; Women had higher scores on total ESV (20.55) and Limitation (11.25). The G1.1 subgroup showed higher auditory temporal ordering ability in the TPF, both in Humming (OD = 100% and OE = 99.75%), and in Nomination (OD = 96.89% and EO = 97.77 %), with G3 showing the lowest averages; males were better in both TPF (Humming OD = 97.74% and EO = 97.66%, ND = 94.15% and EO = 94.60%), as in RGDT (4.48). Only negligible strength correlations were found between the different central auditory processing tests, the general degree of vocal deviation in the auditory perceptual analysis of vocal quality, and the different scores of the Signals and Vocal Symptoms Scale protocol. CONCLUSION: The vocal quality of musicians and non-musicians correlated with their auditory processing, although with negligible strength. It was found that the singers reported more vocal symptoms in relation to the other groups, due to the probable awareness of their instrument, as well as the women when compared to the men. As for auditory processing, there was great variation in all groups. However, musicians, mainly instrumental singers, demonstrated a better auditory ability of temporal ordering, suggesting that the study and musical experience can be responsible for this performance. For this same aspect, regarding the influence of gender on the auditory abilities, it was verified that the men have better results in the tests of ordering and temporal resolution.
