Summary
Individuals with homonymous visual field defects (iwHs) face reading challenges. A new questionnaire, the Hemianopia Reading Questionnaire (HRQ), effectively measures these reading difficulties for better rehabilitation outcomes.
Area of Science:
- Neuroscience
- Ophthalmology
- Psychometrics
Background:
- Reading is crucial for daily functioning.
- Homonymous visual field defects (iwHs) following brain injury often cause significant reading impairments.
- Existing tools may not fully capture the diverse reading difficulties experienced by individuals with iwHs.
Purpose of the Study:
- To introduce and validate the Hemianopia Reading Questionnaire (HRQ), a novel self-report measure for reading difficulties in individuals with iwHs.
- To assess the psychometric properties of the HRQ, including its factor structure, reliability, and validity.
- To provide a tool that can aid in the reading rehabilitation of individuals with iwHs.
Main Methods:
- Development of a 24-item HRQ with input from clinical experts and individuals with lived experience.
- Testing of the HRQ's factor structure, reliability, and validity in a large community sample (N=998) representative of stroke survivors.
- Analysis using two competing hypothesized models, with a three-bifactor model showing a good fit.
Main Results:
- A three-bifactor model provided a good fit for the HRQ data.
- The HRQ demonstrated good reliability across its three subscales (omega range 0.93-0.99).
- Convergent and divergent validity were supported, with 9 out of 12 correlations meeting expectations.
Conclusions:
- The Hemianopia Reading Questionnaire (HRQ) is a psychometrically sound instrument for measuring reading difficulties in individuals with iwHs.
- The HRQ is suitable for use in clinical settings and research, particularly for guiding reading rehabilitation efforts.
- Further psychometric research on the HRQ is warranted to explore its full potential.

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.
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...
01:22Self-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.
01:28Self-Esteem
Self-esteem, a core aspect of psychological well-being, reflects an individual's positive and negative self-evaluation in terms of worth, competence, and overall value. It is both a stable trait and a dynamic process, influenced by experiences and social interactions across the lifespan. While global self-esteem offers a general assessment, research highlights that self-esteem is multidimensional and varies across specific life domains.Domain-Specific Self-EsteemResearchers have delineated...
01:27Sources of Self-Esteem III: Social Comparison
Social comparison plays a fundamental role in the evaluation of personal success and self-worth. Rather than assessing our achievements in isolation, we interpret their significance relative to personal goals and critically in comparison to the performance of others. A grade of B in a mathematics exam might elicit pride if one's expectation was a C, yet result in disappointment if an A was anticipated or if peers achieved superior results. These comparative evaluations illustrate how both...
01:27Halo Effect
The halo effect is a cognitive bias in which an individual's overall impression influences judgments about their specific traits. This psychological phenomenon leads people to associate positive characteristics with those they perceive as generally good and negative characteristics with those they view as bad. This effect is particularly influential in social perception, professional evaluations, and decision-making processes.The Psychological Basis of the Halo EffectThe halo effect is rooted...
