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.

Cochran's Q Test

Cochran's Q Test

Cochran's Q Test is a nonparametric statistical test used to determine if there are potential differences in the outcomes of three or more related groups on a binary (yes/no) or dichotomous outcome. It is essentially an extension of the McNemar Test, which is limited to two related samples - Cochran's Q test can handle three or more related samples, making it more versatile in scenarios where subjects are measured under multiple conditions. The test statistic follows a Chi-Square distribution,...

Area of Science:

Psychiatry and Behavioral Sciences
Public Health
Survey Methodology

Background:

Quantitative instruments often lack psychometric validation for specific populations like homeless individuals with mental disorders.
Supported housing interventions require reliable measurement tools to assess outcomes effectively.

Purpose of the Study:

To evaluate the relevance, comprehension, and acceptability of questionnaire items using cognitive interviewing.
To identify necessary modifications for instruments used in a supported housing trial for homeless adults with mental disorders.

Main Methods:

Cognitive interviewing was employed with 30 homeless adults with mental disorders across three Canadian sites.
Trained interviewers tested selected questionnaire items focusing on physical/mental health, housing, service use, and community integration.
Findings were collated, and conclusions validated by interviewers.

Main Results:

Many questionnaire items lacked relevance for the homeless population.
Comprehension varied significantly, highlighting the need for understanding checks and aids, especially for those with cognitive impairment or acute symptoms.
Item acceptability varied, underscoring the importance of the "how you ask" aspect of data collection.

Conclusions:

Cognitive interviewing is a valuable method for refining measurement tools for unique populations.
Pretesting instruments is crucial for interviewer training, enhancing measurement, and ensuring accurate interpretation of findings in trials involving vulnerable groups.
Adapting survey instruments is essential for valid and reliable data collection among homeless individuals with mental disorders.
