在咨询了苏格兰四家癌症家庭诊所的临床医生后，制作了一段关于乳腺癌遗传易感性的介绍性信息视频。128名新被转介接受乳腺癌风险咨询的女性被随机分配到咨询前(n=66)或咨询后(n=62)接受视频。在临床随机分组之前收集数据，并在1个月时通过邮寄随访收集数据。视频前组与乳房外科医生的会诊时间较短(平均值=11.8min+/-5.4vs 14.6+/-7.2)。两组之间在咨询后风险估计的准确性上没有差异，尽管在自我报告方面，视频之前组得分更高(Z=3.65，D.F.=1，P<；0.01)和客观评估理解(Z=2.91，D.F.=1，P<；0.01)。在1个月的随访中，先于视频组不太可能低估他们的风险估计(38%比18%；chi2=4.62，D.F.)。=1，P<；0.05)，但两组之间在主观或客观认识上没有差异。视频的使用与增加的痛苦(GHQ，斯皮尔伯格状态焦虑)无关，而与对诊所提供的信息更满意有关。这项研究支持了录像带作为一种为女性准备乳腺癌风险咨询提供信息的方法的价值。对误解和痛苦的观察强调，这段视频应该被视为诊所沟通的帮助，而不是替代品。
A video of introductory information about inherited susceptibility to breast cancer was made in consultation with clinicians in four Scottish cancer family clinics. One hundred and twenty-eight women, newly referred for breast cancer risk counselling were randomized to receive the video before (n = 66) or after (n = 62) counselling. Data were collected before randomization at clinic and by postal follow-up at 1 month. The Video Before group had shorter consultations with the breast surgeon (mean = 11.8 min+/-5.4 vs 14.6+/-7.2 for the Video After group). There was no difference between the groups in the accuracy of their risk estimate after counselling, although the Video Before group scored higher for self-reported (Z= 3.65, d.f. = 1, P < 0.01) and objectively assessed understanding (Z= 2.91, d.f. = 1, P < 0.01). At 1 month follow-up, the Video Before group were less likely to underestimate their risk estimate (38% vs 18%; chi2 = 4.62, d.f. = 1, P< 0.05), but there was then no difference between the groups in subjective or objective understanding. Use of the video was not associated with increased distress (GHQ, Spielberger State Anxiety) and was associated with greater satisfaction with the information given at the clinic. This study supports the value of videotape as a method of giving information to prepare women for breast cancer risk counselling. Observations of misunderstandings and distress emphasize the video should be seen as an aid to, not a substitute, for communications at the clinic.
