Özet

Objective: This study examines the Turkish validity, reliability and diagnostic performance of the Voice Handicap Index-Partner (VHI-P-TR), which is used to obtain the perceptions of communication partners of individuals with dysphonia about the functional, physical and emotional handicap resulting from the patient experiencing dysphonia. Method: The study included 160 individuals with dysphonia and their communication partners. First, translation, back translation, expert validity and pilot study were performed in the scale adaptation process. Then, a confirmatory factor analysis (CFA) was conducted to assess the construct validity of the VHI-P-TR. Correlations between the VHI-P-TR and Voice Handicap Index (VHI-TR) scores of dysphonic individuals were examined to evaluate the concurrent validity of the VHI-P-TR. To assess the reliability of the VHI-P-TR, a test-retest analysis was performed, and internal consistency coefficients (α) were calculated. A receiver operating characteristic (ROC) analysis was conducted to determine the cut-off point for the VHI-P scores. Results: A high positive correlation was found between the participants’ VHI-P-TR and VHI-TR total and subscales mean scores (r's > 0.782; p < 0.01). The VHI-P-TR had high internal consistency regarding for its subscales and total score (α's > 0.94; p < 0.01). Factor loadings of all VHI-P-TR items were higher than 0.30 and their error variances were lower than 0.90. In addition, factor loadings were statistically significant for all the items (p < 0.05). The data fit the model well according to all CFA indices except for GFI (scale = 0.69). An adequate sensitivity and specificity were achieved for the VHI-P-TR, and the cut-off point was found as 11.50 for the total score and ranged from 2.50 to 5.50 for the subscales. Conclusion: The VHI-P-TR is a valid and reliable measurement tool with high diagnostic performance in all subscales and total score, and has high levels of agreement with the VHI-TR.
