Reliability and Validity

Reliability 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.

Social Proof

Social proof is a form of persuasion based on comparison and conformity. People compare their behavior and actions to what others are doing and will change to conform to do what their peers do.

Barriers to Effective Communication II

Barriers to Effective Communication II

The barriers to effective communication also include cultural barriers, semantic barriers, gender barriers, and time constraints.
Cultural barriers:
Differences in values, beliefs, religion, knowledge, and tradition can significantly impact communication. Awareness of nonverbal cues is critical, especially when conversing with a patient from a different culture. What appears appropriate in one culture may be inappropriate in another.
Semantic barriers:
As a result of their tendency to use...

Self-Report Tests of Personality

Self-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.

Barriers to Effective Communication I

Barriers to Effective Communication I

A communication barrier is any distortion or interruption during a conversation, resulting in miscommunication of the message. A good communicator should know these barriers and continuously check for the listener's understanding by obtaining feedback.
Communication barriers include the following:
Physiological barriers: They are limitations caused by a person's health condition or disability, such as hearing loss, poor eyesight, illness, or unconsciousness. An example to overcome this barrier...

Surveys

Surveys

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.

Summary

The Communicative Effectiveness Survey (CES) shows construct validity for individuals with Parkinson's disease (PD) and dysarthria. PD patients rated their communication effectiveness lower than healthy individuals, highlighting the need for comprehensive assessment.

Area of Science:

Speech-language pathology
Neurology
Psychometrics

Background:

Idiopathic Parkinson's disease (PD) often leads to dysarthria, impacting communication.
Assessing communicative effectiveness in PD is crucial for patient well-being and treatment.
The Communicative Effectiveness Survey (CES) is a tool to measure perceived communication ability.

Purpose of the Study:

To establish preliminary construct validity of the CES for individuals with PD and dysarthria.
To evaluate the CES's utility in differentiating communication effectiveness between PD patients and controls.
To explore the relationship between CES ratings and objective speech measures in PD.

Main Methods:

A prospective, quasi-experimental study with 75 participants in three groups: PD with dysarthria, non-PD without dysarthria, and PD significant others (SOs).
CES ratings were compared between the PD and non-PD groups, and between PD patients and their SOs.
Multiple linear regression analyzed predictors of CES ratings, including sentence and spontaneous speech intelligibility.

Main Results:

The PD group reported significantly lower CES ratings than the non-PD group.
PD patients rated their own communication effectiveness higher than their SOs rated them.
Speech intelligibility scores did not predict CES ratings; however, Hoehn and Yahr PD staging explained 47% of CES variability in the PD group.

Conclusions:

The study provides initial evidence supporting the construct validity of the CES for individuals with PD and dysarthria.
Clinicians and researchers assessing PD communication should consider incorporating the CES alongside traditional measures like speech intelligibility.
The CES offers valuable insights into the patient's perceived communicative effectiveness, complementing objective assessments.
