Quality of life analysis of teachers in a primary school in Chengdu

Abstract

Objective:To investigate the prevalence of voice disorder and quality of life in the primary school teachers in a certain district of Chengduand examine the correlation between two voice-specific questionnaires.Method:Random sampling survey included 389 teachers from a certain district of Chengdu.Twelve item general health questionnaire(GHQ-12),voice handicap index 10(VHI-10) and voice-related quality of life (V-RQOL) were investigated and routine examination of throat with electronic fiber laryngoscopy were carried out for teachers.Result:There were 189 teachers who had voice disorders(voice disorders group),and 200 teachers who did not have voice disorders(control group).②The total score's difference of V-RQOL and VHI-10,functional(F) and emotion(E) dimensions in VHI-10 between two groups were statistically significant(P<0.05),however,there were no statistically significant difference of GHQ-12 between two groups. The total score of GHQ-12 was positively correlated with VHI-10(r=0.194,P <0.05),while the total score of V-RQOL was negatively correlated with GHQ-12(r=-0.209,P<0.05) and VHI-10 (r=-0.586, P <0.05).Conclusion:Voice disorders can affect teachers' psychology and voice related quality of life.Although the VHI-10 and V-RQOL had correlation,the correlation is not strong.So it is recommended combine VHI-10 and V-RQOL when the quality of life of voice disorders is evaluated.
