Client ratings of the credibility of prescriptive and exploratory therapies were compared, and correlated with clinical improvement. Both expectancies and outcomes favoured prescriptive therapy in the first, but not the second, period of a cross-over design, and modest correlations were obtained between credibility and improvement. Regression analysis suggested that the impact of expectancy on outcome was secondary to the treatment effect rather than its cause.
比较了患者对指导性疗法和探索性疗法可信度的评级，并将其与临床改善情况相关联。在交叉设计的第一个阶段（而非第二个阶段），期望和结果均有利于指导性疗法，并且在可信度与改善之间获得了适度的相关性。回归分析表明，期望对结果的影响是治疗效果的次要因素而非其原因。
