Differences between early and late drop-outs from treatment for obsessive-compulsive disorder Academic Article uri icon

abstract

  • To examine characteristics of drop-outs from treatment for obsessive–compulsive disorder (OCD), we studied 121 participants who underwent exposure or cognitive treatment, either alone or with fluvoxamine. OCD symptoms were assessed at pre-treatment, post-treatment, and at every session. No differences in attrition were found between treatment conditions. Drop-outs from treatment (n = 31) were divided into early (before session 6) and late (session 6 or after) drop-outs. We found that early drop-outs had more severe OCD symptoms at termination compared to completers, whereas late drop-outs did not differ from treatment completers. Higher levels of depressive symptoms were associated with early drop-outs, and lower levels with completers. These findings suggest that individuals with high levels of pretreatment depression are at risk for early drop-out with elevated OCD symptoms. Conversly, late drop-outs may be treatment responders who drop out after experiencing substantial improvement. Implications for allocation of resources for attrition prevention are discussed.
