to analyze the relationship between sense of coherence and sociodemographic data, remote physical work environment, and self-perception of symptoms, vocal handicap and vocal fatigue in teachers.
Seventy eight teachers pertaining to the municipal education network of a Brazilian capital city participated in the study, during the period of social isolation by COVID-19. An online questionnaire was applied with sociodemographic and physical remote work environment questions, the Sense of Coherence Scale (SOC-13), the Brazilian Dysphonia Screening Tool (Br-DST), the Vocal Fatigue Index (VFI), and the Vocal Handicap Index (VHI-10). Descriptive analysis, bivariate and multivariate Logistic regression models were performed to check the proportion of teachers with high and low SOC among the different categories of independent variables. Student's t test and Mann Whitney test were used to compare SOC, IDV, and VFI scores between the groups, and Hedge's g test was used to access the effect size. The total scores of SOC, VHI and VFI were correlated using Pearson's Correlation Coefficient. All tests adopted a 5% significance level.
Male teachers and those over 45 years old were, respectively, 6.79 (95%CI = 1.16-39.58) and 5.27 (95%CI = 1.40-19.76) times more likely to present a high SOC. The variables associated with a lower chance of presenting high SOC were vocal restriction (OR = 0.21; 95%CI = 0.06-0.79) and voice-related physical discomfort (OR = 0.13; 95%CI = 0.02-0.78). Regarding the remote work environment, in bivariate analysis, teachers who were dissatisfied with air quality (OR = 0.08; 95%CI = 0.01-0.65), temperature (OR = 0.11; 95%CI = 0.01-0.92), and noise (OR = 0.25; 95%CI = 0.61-0.99) were less likely to have high SOC. Higher values of SOC are associated with lower self-perception of vocal fatigue and voice handicap (P < 0,001).
The way individuals face stressful situations interferes with the self-perception of their voice and their work environment. The relationship between the sense of coherence and voice perception is relevant to favor programs to promote vocal health and stress management in teachers.
分析连贯感与社会人口学数据、远程物理工作环境以及教师症状自我认知、嗓音障碍和嗓音疲劳之间的关系。
78名来自巴西一座首府城市市立教育网络的教师在因新冠疫情而社会隔离期间参与了本研究。应用了一份在线问卷，其中包含社会人口学和远程物理工作环境问题、连贯感量表（SOC-13）、巴西嗓音障碍筛查工具（Br-DST）、嗓音疲劳指数（VFI）和嗓音障碍指数（VHI-10）。进行描述性分析、双变量和多变量逻辑回归模型，以检查不同类别自变量中高SOC和低SOC教师的比例。使用学生t检验和曼-惠特尼检验比较各组之间的SOC、IDV和VFI分数，并使用赫奇斯g检验评估效应大小。使用皮尔逊相关系数对SOC、VHI和VFI的总分进行相关性分析。所有检验均采用5%的显著性水平。
男性教师和45岁以上的教师出现高SOC的可能性分别是其他教师的6.79倍（95%置信区间=1.16-39.58）和5.27倍（95%置信区间=1.40-19.76）。与出现高SOC可能性较低相关的变量有声带受限（比值比=0.21；95%置信区间=0.06-0.79）和与嗓音相关的身体不适（比值比=0.13；95%置信区间=0.02-0.78）。关于远程工作环境，在双变量分析中，对空气质量不满意（比值比=0.08；95%置信区间=0.01-0.65）、温度不满意（比值比=0.11；95%置信区间=0.01-0.92）和噪音不满意（比值比=0.25；95%置信区间=0.61-0.99）的教师出现高SOC的可能性较小。较高的SOC值与较低的嗓音疲劳和嗓音障碍自我认知相关（P<0.001）。
个体面对压力情况的方式会影响他们对嗓音和工作环境的自我认知。连贯感与嗓音认知之间的关系对于支持促进教师嗓音健康和压力管理的项目具有重要意义。
