This report presents data from a telephone survey of a randomly selected sample of 292 marriage and family therapists (MFTs) who were Clinical Members of the American Association for Marriage and Family Therapy. The study, designed to better understand the current state of the field of MFT, provides descriptive data on the demographic characteristics, training, clinical practices, and treatment of substance abuse disorders by MFTs. Participants reported they most commonly treat marital and couple difficulties, depression, anxiety, and problems of children and adolescents. It was also found that MFTs commonly assess for substance abuse problems, but these problems represent a relatively small percentage of their caseload. The data support the continued maturation and growth of the field. Implications for the field and comparisons to other national data are addressed.
