Summary
The Arabic Voice Activity and Participation Profile (A-VAPP) is a reliable tool for assessing voice disorders in Saudi Arabia. It effectively measures the impact of voice problems on daily life and social participation.
Area of Science:
- Speech and Hearing Sciences
- Clinical Psychology
- Health Services Research
Background:
- Voice disorders significantly impact daily activities and social participation.
- Existing assessment tools may not be culturally or linguistically adapted for Arabic-speaking populations.
- The Voice Activity and Participation Profile (VAPP) is a comprehensive measure of voice disorder impact.
Purpose of the Study:
- To translate the VAPP into Arabic (A-VAPP).
- To validate the A-VAPP for assessing voice disorders in Saudi Arabia.
- To test the reliability and validity of the A-VAPP in Arabic-speaking patients.
Main Methods:
- Forward and backward translation of the VAPP into Arabic.
- Descriptive, questionnaire-based validation study with 120 participants (60 with voice complaints, 60 healthy controls).
- Reliability assessed using Cronbach's alpha and test-retest (ICC); validity assessed using EFA and Mann-Whitney U test.
Main Results:
- The A-VAPP demonstrated excellent reliability (Cronbach's alpha=0.967, ICC > 0.979).
- Significantly higher impact scores were found in voice complaint patients across job, daily communication, social communication, and emotional domains.
- Strong discriminative validity was confirmed (AUC=0.960, sensitivity=84%, specificity=100%).
Conclusions:
- The Arabic VAPP (A-VAPP) is a reliable and valid instrument.
- A-VAPP is suitable for assessing voice disorders in Arabic-speaking patients.
- The tool can be utilized in both clinical practice and research settings.

01:29Reliability and Validity
Reliability and validity are two important considerations that must be made with any type of data collection. Reliability refers to the ability to consistently produce a given result. In the context of psychological research, this would mean that any instruments or tools used to collect data do so in consistent, reproducible ways.
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.

01:29Assessment of Ventilation II: Respiratory Depth and Rhythm
Respiratory Depth
Respiratory depth measures the volume of air inhaled or exhaled during a breath. It can vary from shallow to deep and typically remains consistent when a person is at rest or asleep. Occasionally, individuals will automatically inhale deeply, known as sighing, which inflates the lungs with more air than normal breathing.
To assess respiratory depth, observe the degree of chest excursion or movement:

01:25Assessment of apical radial pulse
Apical-Radial (A-R) Pulse Assessment
The A-R pulse assessment involves simultaneous evaluation of the apical and radial pulses. When the apical and radial pulse rates vary, this assessment helps identify a pulse deficit.

02:16Surveys
Often, psychologists develop surveys as a means of gathering data. Surveys are lists of questions to be answered by research participants, and can be delivered as paper-and-pencil questionnaires, administered electronically, or conducted verbally. Generally, the survey itself can be completed in a short time, and the ease of administering a survey makes it easy to collect data from a large number of people.
