McGill Friendship Questionnaire [MFQ-100]

Description and Purpose

The McGill Friendship Questionnaire (MFQ-100) is a psychometric instrument designed to assess the quality, characteristics, and emotional dimensions of friendship relationships. It focuses on how individuals perceive and evaluate their friendships, including aspects such as support, trust, mutual understanding, shared activities, and emotional bonds.

Rather than assessing friendship simply in terms of the number or presence of friends, the MFQ-100 approaches friendship as a multidimensional interpersonal relationship. Particular emphasis is placed on perceived relationship quality, emotional closeness, and the psychological and social benefits individuals derive from their friendships.

Theoretical Background

The MFQ is based on the assumption that friendship quality can be understood through several distinct but interrelated relational experiences and functions.

These include support, trust, mutual understanding, shared experiences, companionship, and emotional connection. Such dimensions provide information not only about whether an individual has friendships but also about the perceived value and quality of those relationships.

This multidimensional approach allows friendship to be examined as an important component of interpersonal and psychosocial functioning.

Structure and Dimensions

According to the provided material, the MFQ-100 consists of 100 items addressing different aspects of friendship experiences.

The principal areas assessed include:

Support: Refers to the extent to which a friend is perceived as available to provide assistance, encouragement, and support when needed.

Trust: Assesses feelings of security, reliability, and confidence within the friendship.

Mutual Understanding: Reflects the extent to which friends are perceived as understanding each other’s thoughts, feelings, experiences, and needs.

Shared Activities: Examines participation in common activities and experiences that contribute to maintaining and strengthening the friendship.

Emotional Bond: Refers to emotional closeness, satisfaction, attachment, and positive feelings associated with the friendship.

Examining these dimensions separately can provide a more detailed profile of friendship quality than relying exclusively on a single overall score.

Objectives

The primary objective of the MFQ-100 is to provide a quantitative and multidimensional assessment of friendship quality.

More specifically, the questionnaire can be used to assess perceived support, trust, mutual understanding, commitment, and emotional connection within friendships.

It may also facilitate comparisons between different types of friendships, such as close versus more superficial relationships, and contribute to research investigating how friendship quality relates to psychological variables such as well-being, self-esteem, and perceived social support.

Administration and Scoring

Participants respond to questions concerning different characteristics of their friendships. According to the provided material, responses generally use Likert-type scales, commonly with five or seven response categories.

Responses can be combined to generate overall and dimension-specific scores, depending on the structure and scoring system of the version being administered.

Higher scores on positively oriented dimensions would generally indicate greater perceived friendship quality or a stronger presence of the corresponding friendship characteristic.

However, the provided material does not specify the exact allocation of the 100 items to individual dimensions, a complete scoring key, reverse-scored items, or a definitive theoretical score range. Therefore, scoring should follow the instructions established for the specific version of the questionnaire.

Data Analysis and Use

MFQ-100 data can be examined at both the overall friendship-quality and individual-dimension levels.

Descriptive statistics such as the mean, standard deviation, median, and score range can be calculated to summarize participants’ responses.

Relationships between friendship quality and other psychological or social variables may be examined using correlation analyses. Relevant variables may include psychological well-being, self-esteem, perceived social support, and family or interpersonal relationships.

Group differences may be investigated using t-tests, ANOVA, or appropriate non-parametric alternatives, depending on the characteristics and distribution of the data.

In psychometric research, Exploratory Factor Analysis (EFA) and Confirmatory Factor Analysis (CFA) may be used to investigate the underlying dimensional structure of the questionnaire.

Validity

The validity of the MFQ-100 concerns the extent to which its scores adequately represent the quality and characteristics of friendship relationships.

Construct validity may be examined through factor-analytic procedures, while convergent and discriminant validity may be investigated by examining relationships with theoretically related or distinct psychological constructs.

Associations with measures of social support, psychological well-being, self-esteem, and interpersonal functioning may provide useful evidence regarding the construct represented by the questionnaire.

Reliability

The internal consistency of the MFQ-100 and its individual dimensions can be evaluated using Cronbach’s alpha.

Higher internal-consistency coefficients indicate that items designed to assess the same friendship dimension demonstrate an adequate degree of consistency.

The provided material does not report specific numerical reliability coefficients. Consequently, a particular Cronbach’s alpha value should not be attributed to the MFQ-100 without additional evidence regarding the specific version and population being assessed.

Applications

The MFQ-100 may be used in research examining friendship, interpersonal relationships, social support, and psychosocial adjustment.

It can contribute to investigations of differences in friendship quality across different demographic, developmental, or social groups and to studies examining relationships between friendship and well-being, self-esteem, social support, and other psychological outcomes.

The questionnaire may also be useful in longitudinal research examining changes in friendship relationships over time and in studies investigating the potential protective role of high-quality interpersonal relationships.

Conclusion

The McGill Friendship Questionnaire [MFQ-100] provides a structured framework for the multidimensional assessment of the quality and nature of friendship relationships.

By examining characteristics such as support, trust, mutual understanding, shared activities, and emotional connection, the questionnaire can contribute to a more comprehensive understanding of the role of friendship in psychological well-being, social functioning, and interpersonal adjustment.
