Abstract
This study aimed at examining vocal fatigue symptoms in secondary school teachers. The study sample comprised 40 willing premenopausal female secondary school teachers (age range: 22– 45yrs). All participants completed a 16-item vocal fatigue questionnaire with a 4-point rating scale, where, never, sometimes, most of the times, and always which were given numerical values 0, 1,2,3, respectively for the analysis.
The total mean score of vocal fatigue was 11.95 ± 6.5. Symptoms were divided into 2 groups: (1) 7 physical-related symptoms (PRSs) and (2) 9 voice-related symptoms (VRSs).
Of the PRSs, tension in the neck/shoulder, dryness in the throat, and urge for throat clearing were more commonly reported with varying severity (≥65%), and of the VRSs, harshness and breathiness were reported with varying severity (≥65%). Of the VRSs, pitch range affected (72.5%), loudness range affected (72.5%), and harshness (70%) were more commonly reported, and of the PRSs, the urge for coughing was reported by most of the teachers (80%). A significantly high positive correlation was observed between PRSs and VRSs (r= 0.75), whereas no significant correlation was observed between vocal fatigue ratings and age and classes taken per week. Symptoms for which≥60% of the subjects responded with ‘sometimes’ were considered as sensitive indicators of vocal fatigue. These included pain in the throat, dryness in the throat, tightness in the throat, urge for coughing, pitch range affected, loudness range affected, hoarseness, harshness, and pitch breaks. These 9 indicators could be used for the early screening of vocal fatigue.
