Three types of individual drug abuse counseling were investigated in a private methadone clinic in order to replicate and extend previous work on node-link mapping techniques (two dimensional graphic approaches for visualizing problems and solutions). Standard counseling, enhanced counseling with free-form maps (f-maps), and enhanced counseling with both f-maps and guide-maps (g-maps) were compared at six and 12 months of treatment. Also assessed were differential effects of these counseling conditions on clients with low and high levels of behaviors related to attention deficit hyperactivity disorder (ADHD; low-problem versus high-problem clients). Dependent variables included the number of scheduled sessions attended per month, counselor ratings of session characteristics (e.g., powerful, valuable), client psychological status ratings (i.e., self-esteem, depression, and anxiety) and treatment retention (i.e., the number of months clients remained in treatment). Findings replicate and extend prior work indicating the positive impact of using node-link maps in individual drug abuse counseling. Particular benefits were found for clients with high levels of ADHD-related problems
