Summary
This study found patient self-assessment of voice problems correlates with loudness and glottic closure issues, not frequency control. Objective voice measures partially align with subjective ratings, aiding dysphonia assessment.
Area of Science:
- Otolaryngology
- Speech and Language Pathology
- Acoustic Analysis
Background:
- Effective voice disorder assessment requires both subjective and objective measures.
- Comparing these measures is crucial for understanding their utility in evaluating dysphonia.
Purpose of the Study:
- To investigate the correlation between objective voice measurements and patients' subjective self-assessment of their voice problems.
Main Methods:
- 100 patients with voice complaints underwent a protocol including auditory perceptual assessment, acoustic voice analysis, aerodynamic measures, and the Voice Problem Self-Assessment Scale (VPSS).
Main Results:
- Variable correlations were observed between VPSS functional/emotional clusters and dysphonia grade.
- The Dysphonia Severity Index (DSI) showed moderate correlation with VPSS total and emotional scores.
- Acoustic parameters (Shimmer, APQ, NHR) and Maximum Phonation Time (MPT) correlated with VPSS total and emotional scores; subglottic pressure predicted phonasthenic cluster scores.
Conclusions:
- Patient self-perception of voice issues is linked to difficulties with loudness control and glottic closure.
- The findings suggest that subjective voice assessments are influenced by specific objective parameters related to vocal fold function.

03:00Self-Evaluation: Self-Enhancement and Self-Verification
Social psychologists have documented that feeling good about ourselves and maintaining positive self-esteem is a powerful motivator of human behavior (Tavris & Aronson, 2008). In the United States, members of the predominant culture typically think very highly of themselves and view themselves as good people who are above average on many desirable traits (Ehrlinger, Gilovich, & Ross, 2005). Often, our behavior, attitudes, and beliefs are affected when we experience a threat to our...
01:24Strategies of Self-Presentation III: Self-Monitoring
Self-monitoring is a central construct in understanding individual differences in self-presentation strategies across social contexts. It refers to how individuals observe, regulate, and control their expressive behavior and self-presentation following situational cues. Self-monitoring reflects a person's sensitivity to social appropriateness and willingness to adapt behavior to fit varying interpersonal demands.High vs. Low Self-Monitoring IndividualsIndividuals high in self-monitoring are...
01:30Social Foundations of Self III: Self-Evaluation
Self-evaluation is the process by which individuals assess their abilities, behaviors, and characteristics based on feedback from others. Charles H. Cooley observed that a person’s self-perception is primarily influenced by how others see and judge them. He suggested that individuals form their identities based on their interpretations of others' reactions. As a result, social interactions play a crucial role in shaping self-esteem and personal identity. These external evaluations often blend...
01:29Self-Evaluation Maintenance Model
The Self-Evaluation Maintenance (SEM) model offers a psychological framework to understand how individuals’ self-esteem is influenced by the achievements of others, particularly those with whom they share close personal bonds. The SEM model operates when personal rather than social identity guides individuals. Central to this model is the notion that individuals have an inherent desire to preserve a favorable self-image, which is continuously shaped by interpersonal comparisons and...

Assessment of Ventilation
A Ventilation assessment is critical for monitoring a patient's health status. Respiration, one of the most accessible vital signs, provides insights into the function of numerous body systems and can indicate serious health issues, such as brainstem injuries from head trauma.

01:22Self-Report Tests of Personality
Self-report inventories are objective personality assessments that use multiple-choice items or numbered scales, typically ranging from 1 (strongly disagree) to 5 (strongly agree). They are often called Likert scales after Rensis Likert. These inventories are widely used due to their ease of administration and cost-effectiveness. One of the most prominent examples is the Minnesota Multiphasic Personality Inventory (MMPI), initially developed in the 1940s to assess abnormal personality traits.
