The present study examined the effects of sudden gains on treatment outcome in a randomized controlled trial including individual cognitive therapy (CT) and interpersonal therapy (IPT) for social anxiety disorder (SAD).
Participants were 67 individuals with SAD who received 16 treatment sessions. Symptom severity at each session was assessed using the Social Phobia Weekly Summary Scale (Clark et al., 2003).
Results indicate that 22.4% of participants experienced a sudden gain during treatment. Individuals with sudden gains had significantly lower social anxiety symptoms at post-treatment and follow-up compared to individuals without sudden gains. Sudden gains in CT and IPT had similar magnitudes, frequencies, and timings. However, sudden gains resulted in lower levels of post-treatment symptoms in CT compared to IPT. Cognitive changes did not precede sudden gains, but sudden gains resulted in cognitive changes.
Sudden gains in CT and IPT for SAD are predictive of long-term outcome. In addition, the effect of sudden gains may be greater in CT compared to IPT.
本研究通过一项随机对照试验，考察了突然获益对个体认知疗法（CT）和人际治疗（IPT）治疗社交焦虑障碍（SAD）的疗效的影响。
67 名 SAD 患者参与了这项研究，他们接受了 16 次治疗。在每次治疗时，使用社交恐惧症每周总结量表（Clark 等人，2003）评估症状严重程度。
结果表明，治疗期间有 22.4%的参与者经历了突然获益。与没有突然获益的参与者相比，突然获益的参与者在治疗后和随访时的社交焦虑症状明显减轻。CT 和 IPT 中的突然获益具有相似的幅度、频率和时间。然而，与 IPT 相比，CT 中的突然获益导致治疗后症状水平更低。认知变化并未先于突然获益发生，但突然获益导致了认知变化。
SAD 中 CT 和 IPT 的突然获益是长期疗效的预测因素。此外，与 IPT 相比，CT 中的突然获益效果可能更大。
