“…Nine studies examined the impact of concurrent use of any psychotropic medication on symptom improvement in CBT, and all found that use of psychotropic medication did not predict improvement at post-treatment (Aaronson et al, 2008;Arch & Craske, 2007;Arntz, 2002;Côté, Gauthier, Laberge, Cormier, & Plamondon, 1994;Hecker, Losee, Fritzler, & Fink, 1996;Kenardy et al, 2003;McLean et al, 1998;Rufer, Albrecht, Zaum et al, 2010;Steketee et al, 2001; see Table 1), though Arch and Craske found that use of medication marginally predicted decreased improvement on one of two outcome measures. In three of these nine studies, patients were prohibited from changing their medication or dosage during treatment (Hecker et al, 1996;Kenardy et al, 2003;McLean et al, 1998;Steketee et al, 2001), indicating that these null findings cannot be attributed to a lack of predictive power due to changes in medication during treatment.…”
