This study investigated the long-term efficacy of three 45-minute sessions of live graded exposure, computer-aided vicarious exposure, or progressive muscle relaxation placebo for the treatment of spider phobia, and is a follow-up of the results previously reported by Gilroy, Kirkby, Daniels, Menzies, and Montgomery (2000). Forty-two out of 45 participants were assessed, using both subjective and behavioral assessments, at a mean of 33 months after completing treatment. The assessor was unaware of treatment group. Results showed significant improvement from pretreatment to 33-month follow-up across a range of measures in all treatment groups, although the group by time interaction was not statistically significant. Between 3-month and 33-month follow-up, no significant change was observed in any group, indicating sustained long-term improvement. The results support previous reports of the long-term efficacy of live graded exposure and indicate similar durable treatment outcome effects for computer-aided vicarious exposure. |
