To assess the efficacy of group psychotherapy (GTP) and/or sildenafil for psychogenic erectile dysfunction (ED).
A randomized controlled single-blind trial was performed at the Institute of Psychiatry of the Medical School of at Universidade de São Paulo, São Paulo, Brazil. In all, 30 men with mild and moderate psychogenic ED were randomized to receive for 6 months: GPT plus 50 mg sildenafil on-demand, or 50 mg sildenafil on-demand exclusively, or GPT exclusively. Changes in score from baseline for three questions of the Erectile Dysfunction Inventory of Treatment Satisfaction (EDITS) were evaluated at endpoint and after 3-months follow-up.
Satisfaction with the treatment, confidence and 'naturalness' increased in the GPT plus sildenafil and GPT exclusively groups (P= 0.001) from baseline to endpoint. The treatment-by-time comparison was not significant at endpoint vs the 3-month follow-up, in the three groups. There was no difference in the sildenafil group in the three study periods (P > 0.05)
Men with mild and moderate psychogenic ED had higher treatment satisfaction, confidence and naturalness in engaging in sexual activity when receiving GPT plus sildenafil or GP exclusively, when compared with sildenafil exclusively, as assessed by these three EDITS questions after 6-months treatment.
评估团体心理治疗（GTP）和/或西地那非治疗心因性勃起功能障碍（ED）的疗效。
这项随机对照单盲试验在巴西圣保罗大学医学院精神病学研究所进行。共有 30 名轻度和中度心因性 ED 男性患者被随机分为三组，接受为期 6 个月的治疗：GTP 联合按需服用 50mg 西地那非、仅按需服用 50mg 西地那非或仅接受 GTP。在终点和 3 个月随访时，使用勃起功能障碍治疗满意度问卷（EDITS）的三个问题评估从基线开始的评分变化。
从基线到终点，GTP 联合西地那非组和 GTP 组的治疗满意度、信心和“自然性”均增加（P=0.001）。三组在终点与 3 个月随访时的治疗与时间比较无统计学差异。在三个研究期间，西地那非组的评分均无差异（P>0.05）。
与仅接受西地那非治疗相比，接受 GTP 联合西地那非或 GTP 治疗的轻度和中度心因性 ED 男性在 6 个月治疗后，通过这三个 EDITS 问题评估，在参与性行为时具有更高的治疗满意度、信心和自然性。
