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.

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.

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.

Background:

Inter-rater agreement is vital for clinical trials relying on interviews.
Assessing the reliability of instruments like the Brief Suicide Questionnaire is crucial.

Purpose of the Study:

To evaluate inter-rater agreement for the Brief Suicide Questionnaire.
To determine the efficiency of multiple ratings for assessing instrument reliability.

Main Methods:

32 psychiatrists rated a videotaped suicidal behavior interview.
The DOMENIC method identified discordant items and raters.

Main Results:

Inter-rater agreement varied from poor to excellent across different scales.
Agreement was appropriate for the Brief Suicide Questionnaire and overall scores.

Conclusions:

The study design efficiently assesses inter-rater agreement in one session.
The Brief Suicide Questionnaire demonstrated appropriate inter-rater reliability.
