Friends' Closeness and Intimacy From Adolescence to Adulthood: Art Captures Implicit Relational Representations in Joint Drawing: A Longitudinal Study.

This longitudinal study, employing a mixed-methods explanatory design, explored the power of art to express aspects of one's inner world using the joint drawing technique, which allows for observation and treatment of implicit representations of relationships. At Time 1 (T1, 1977-1978), 200 adolescents created a joint drawing with either a good friend or with a classmate who was not a friend and filled out the Intimate Friendship Scale (IFS) in relation to their best friend. In 2014 (T2), 36 women and 21 men from the original cohort completed the IFS with regard to a good friend and with regard to their spouse.
