The contention that client insight "causes" symptom reduction was examined
for 12 clients who completed 20 sessions of psychotherapy. Clients rated ta
rget complaints before each counseling session and completed the Important
Events Questionnaire (IEQ; A. L. Cummings, J. Martin, E. T. Hallberg, & A.
G. Slemon, 1992) after each counseling session. Counselors rated target com
plaints for their clients after each session. Three judges rated the IEQs u
sing the Insight Rating Scale (IRS; R. W. Morgan, L. Luborsky, P. Crits-Chr
istoph, H. Curtis, & J. Solomon, 1982). Validity of the IRS was established
by examining the relationship between IRS ratings, counselor-judged insigh
t, and counts of client insight statements, Regression analyses showed that
clients had significant linear increases in insight and significant linear
decreases in target complaint distress across the 20 counseling sessions.
Time-series analyses showed that increases in insight led reductions in tar
get complaints. These results support the importance of insight for symptom
reduction.
