Patients seeking psychotherapy often spend time on waitlist (WL), the effect of which is largely unknown. WL patients may forego alternative non-psychotherapeutic assistance and thus do more poorly than had they not been placed on a WL. The course of symptoms might also be influenced by use of antidepressant medication (ADM), an issue that remains unexplored in the literature.
In a naturalistic setting, WL symptom change before inpatient psychotherapy (mean weeks of waiting = 22.6) was assessed in a sample (N = 313) of chronically depressed patients.
Using the Beck Depression Inventory-II, patients' symptoms were tracked at assessment, when admitted to treatment (i.e., after WL), at posttreatment and 1-year follow-up. Multilevel growth curve analysis was used to examine waitlist change for the whole sample as well as for ADM users and nonmedicated patients.
Symptoms were reduced significantly from assessment to admittance (Cohen's d = 0.47). Symptoms reduced less for ADM users (d = 0.39) than for nonmedicated patients (d = 0.65).
The findings indicate that chronically depressed patients experience a decrease in symptoms during WL, quite likely due to treatment expectations. We discuss whether less symptom improvement for ADM users could be attributed to iatrogenic comorbidity and a higher degree of demoralization in this group.
