Friendship Quality Questionnaire – Revised (FQQ-R, Parker & Asher, 1993). I have no experience with this scale, but I have read an article where it was used and it seemed psychometrically adequate. The scale consists of 40 statements that characterize one’s best (or closest) friendship.Children were asked to rate how true each statement is for his or her best friendship on a 5-point scale. The FQQ-R yields six subscales that pertain to different qualitative aspects of friendship: Validation and Caring, Conflict Resolution, Conflict and Betrayal, Help and Guidance, Companionship and Recreation, and Intimate Exchange (alphas ranging from .73 to .90).
This scale is one of the most used instruments with adolescents: Armsden, G., & Greenberg, M (1987). The inventory of parent and peer attachment: Individual differences and their relationship to psychological well-being in adolescence. Journal of Youth and Adolescence, 16, 427-454.
In my opinion, to develop a short, reliable questionnaire regarding the quality of peer relationships perceived by young people / children, it is necessary to:
1. On the basis of previous didactic experience, define the key problems related to the issues of peer relationships perceived by young people / children, such as cooperation, teamwork, mutual respect, help, competition, but also occurring situations of aggression and problem solving methods, teaching methods used in work with children and young people.
2. Identify classic situations, describe typical situations related to defined issues in point 1.
3. Transform the descriptions of typical situations related to defined issues from point 2 to the questions and answers used in the survey.
4. Questions and answers from point 3 should be drawn or presented in the form of photos, rebuses, simple logic puzzles, etc. and thus develop a survey form in a comic-like version.
5. Conduct the survey using the method developed in item 4 survey forms, a form developed in the form of a comic, in a graphic version. This graphic survey form can be posted on the internet and encourage children and young people to take this survey through social media portals.
