Background/Description
The Interpersonal Behaviors Questionnaire (IBQ) is a self-report measure that assesses individual differences in interpersonal behavior. It was developed by William G. Graziano and Joseph A. Raulin in the late 1980s. The IBQ is a 96-item questionnaire that assesses four dimensions of interpersonal behavior: assertiveness, expressiveness, likability, and sociability. These four dimensions are thought to be the key components of interpersonal behavior.
Assertiveness is the extent to which an individual is willing to assert their own rights and interests while also respecting the rights and interests of others. Expressiveness is the extent to which an individual is able to communicate their thoughts, feelings, and emotions effectively. Likability is the extent to which an individual is perceived as friendly, approachable, and likable by others. Sociability is the extent to which an individual is comfortable interacting with and being around other people.
Each item on the IBQ is rated on a 5-point Likert scale, where 1 indicates “strongly disagree” and 5 indicates “strongly agree.” The IBQ has been found to have high levels of reliability and validity, and has been widely used in research on interpersonal behavior and communication. It has been used in studies of personality, social cognition, and interpersonal communication, as well as in applied settings such as education and therapy.
Scoring
The Interpersonal Behaviors Questionnaire (IBQ) is scored by summing the ratings for each item on the questionnaire. Each item is rated on a 5-point Likert scale, where 1 indicates “strongly disagree” and 5 indicates “strongly agree.” The scores for each item are then totaled to obtain a total score for each of the four dimensions of interpersonal behavior: assertiveness, expressiveness, likability, and sociability.
It’s important to note that the scores for each dimension are not directly comparable, as they are based on different numbers of items. Therefore, it is common to standardize the scores by converting them to percentiles or T-scores. These scores can then be used to compare individuals and to identify patterns of interpersonal behavior.
Another way of scoring the IBQ is to use the scores to create group profiles, in which the average scores for a group of individuals are calculated for each dimension. This can be used to compare the interpersonal behavior of different groups of people, such as different cultures or genders, or to assess changes in interpersonal behavior over time.
It’s also important to note that the IBQ is a self-report measure, therefore the scores are subject to biases and limitations of self-reported data. A professional should interpret the results and combine it with other information to form a more complete assessment.
Reliability and Validity
Reliability refers to the consistency of the scores obtained from a measure, while validity refers to the extent to which a measure actually measures what it is intended to measure.
The Interpersonal Behaviors Questionnaire (IBQ) has been found to have high levels of reliability. Studies have reported high internal consistency coefficients for the four dimensions of the IBQ, indicating that the items on the questionnaire are measuring the same construct. Test-retest reliability has also been found to be high, indicating that scores on the IBQ are consistent over time.
The validity of the IBQ has also been well-established. Studies have found that scores on the IBQ are related to other measures of interpersonal behavior and personality in expected ways. For example, high scores on the assertiveness dimension of the IBQ have been found to be associated with high scores on measures of self-esteem and self-confidence, while high scores on the likability dimension have been found to be associated with high scores on measures of social skills and agreeableness.
Additionally, studies have found that the IBQ is able to differentiate between groups of people who are known to differ in their interpersonal behavior. For example, studies have found that men tend to score higher on assertiveness than women, and that people who are high in extraversion tend to score higher on sociability than people who are low in extraversion.
In summary, the IBQ has been found to be a reliable and valid measure of interpersonal behavior and has been widely used in research on interpersonal behavior and communication.
Available Versions
The Interpersonal Behaviors Questionnaire (IBQ) is available in several versions. The original version is the 96-item IBQ, which assesses four dimensions of interpersonal behavior: assertiveness, expressiveness, likability, and sociability.
A short version of the IBQ, called the IBQ-44, which contains 44 items and assesses the same four dimensions of interpersonal behavior as the original IBQ. This shorter version is useful for research and applied settings where time and resources are limited.
A child version of the IBQ, called the Child IBQ, is also available. This version is designed for use with children and adolescents, and assesses the same four dimensions of interpersonal behavior as the adult version of the IBQ.
A version for research with a specific population is also available called the Chinese IBQ, which is translated and adapted for use with Chinese samples.
It’s important to note that translations should be done by professional translators to ensure the accuracy and reliability of the results obtained from the questionnaire.
