This study examined the effects of appraisal of sexual stimuli on sexual arousal in women with superficial dyspareunia (n = 50) and sexually functional women (n = 25). To elicit different appraisals of an erotic film fragment, participants received an instruction prior to viewing it, with a focus on genital pain or on sexual enjoyment. A neutral instruction served as a control condition. Assignment to instruction condition was randomized. Genital arousal (vaginal pulse amplitude) and self-report ratings of affect and genital sensations were obtained in response to the erotic stimulus. As predicted, appraisal of the erotic stimulus affected genital responding, albeit marginally significant. Follow-up tests indicated that women who received the genital pain instruction responded with marginally significant lower genital arousal levels than women who received the sexual enjoyment instruction (d = 0.67). A significant instruction effect for negative affect was found, signifying that negative affect ratings were highest after the genital pain instruction and lowest after the sexual enjoyment instruction (d = 0.80). A marginally significant group by instruction interaction effect was observed for positive affect, indicating that women with dyspareunia reported significantly less positive affect than controls after the sexual enjoyment instruction (d = 1.48). Whereas women with dyspareunia reported overall marginally significant more negative affect than controls (d = 0.48), there were no differences in genital responsiveness between groups. These results provided preliminary evidence for the modulatory effects of appraisal of sexual stimuli on subsequent genital responding and affect in women with and without sexual complaints.

本研究在50例浅表性性功能障碍妇女和25例性功能正常妇女中检验性刺激对性唤醒的影响。为了引发对色情电影片段的不同评价，参与者在观看之前接受了一项指导，重点是生殖器疼痛或性享受。作为控制条件的一条中性指令。对指令条件的分配是随机的。生殖器唤醒(阴道脉搏幅度)和情感和生殖器感觉的自我报告评级是对性爱刺激的反应。正如预测的那样，对性刺激的评估影响了生殖器的反应，尽管影响不大。后续测试表明，接受生殖器疼痛指导的女性与接受性享受指导的女性相比，生殖器唤醒水平略低(d=0.67)。对负性情感的指导作用显著，即负性情感评分在生殖器疼痛指导后最高，在性享受指导后最低(d=0.80)。在积极情感方面，按指导分组交互效应略显着，表明性爱指导后，性交困难妇女报告的积极情感明显低于对照组(d=1.48)。虽然性交困难的妇女报告总体上比对照组的负面影响略显著(d=0.48)，但不同组之间的生殖器反应性没有差异。这些结果为性刺激评估对有和无性主诉的女性随后的生殖器反应和影响的调节作用提供了初步证据。
