To describe trajectories in melanoma survivors' adherence to monthly total skin self-examination (TSSE) over 12 months, and to investigate whether adherence trajectories can be predicted from demographic, cognitive or emotional factors at baseline.
A longitudinal observational study nested within the intervention arm of the ASICA (Achieving Self-Directed Integrated Cancer Aftercare) randomised controlled trial.
Follow-up secondary care in Aberdeen and Cambridge UK.
n=104 adults (48 men/56 women; mean age 58.83 years, SD 13.47, range 28-85 years; mean Scottish Index of Multiple Deprivation score 8.03, SD 1.73, range 2-10) who had been treated for stage 0-IIC primary cutaneous melanoma in the preceding 60 months and were actively participating in the intervention arm of the ASICA trial.
All participants were using the ASICA intervention-a tablet-based intervention designed to support monthly TSSE.
The primary outcome was adherence to guideline recommended (monthly) TSSE over 12 months. This was determined from time-stamped TSSE data recorded by the ASICA intervention app.
Latent growth mixture models identified three TSSE adherence trajectories (adherent -41%; drop-off -35%; non-adherent -24%). People who were non-adherent were less likely to intend to perform TSSE as recommended, intending to do it more frequently (OR=0.21, 95% CI 0.06 to 0.81, p=0.023) and were more depressed (OR=1.31, 95% CI 1.06 to 1.61, p=0.011) than people who were adherent. People whose adherence dropped off over time had less well-developed action plans (OR=0.78, 95% CI 0.63 to 0.96, p=0.016) and lower self-efficacy about TSSE (OR=0.92, 95% CI 0.86 to 0.99, p=0.028) than people who were adherent.
Adherence to monthly TSSE in people treated for melanoma can be differentiated into adherent, drop-off and non-adherent trajectories. Collecting information about intentions to engage in TSSE, depression, self-efficacy and/or action planning at outset may help to identify those who would benefit from additional intervention.

描述黑色素瘤幸存者在 12 个月内每月进行全身皮肤自我检查（TSSE）的依从轨迹，并探讨在基线时，依从轨迹是否可以从人口统计学、认知或情绪因素预测。
嵌套在 ASICA（实现自我导向的综合癌症康复）随机对照试验干预臂中的纵向观察研究。
英国阿伯丁和剑桥的二级保健。
n=104 名成年人（48 名男性/56 名女性；平均年龄 58.83 岁，标准差 13.47，范围 28-85 岁；平均苏格兰多维贫困指数得分 8.03，标准差 1.73，范围 2-10），他们在过去 60 个月内接受了 0-IIC 期原发性皮肤黑色素瘤的治疗，并且正在积极参与 ASICA 试验的干预臂。
所有参与者均使用 ASICA 干预措施-一种旨在支持每月 TSSE 的基于平板电脑的干预措施。
主要结果是在 12 个月内遵循指南推荐的（每月）TSSE。这是通过 ASICA 干预应用程序记录的时间标记的 TSSE 数据确定的。
潜在增长混合模型确定了三种 TSSE 依从轨迹（依从者-41%；下降者-35%；不依从者-24%）。不依从者不太可能按照建议进行 TSSE，他们打算更频繁地进行 TSSE（OR=0.21，95%CI 0.06 至 0.81，p=0.023），而且抑郁程度更高（OR=1.31，95%CI 1.06 至 1.61，p=0.011），依从者。随着时间的推移，依从性下降的人行动计划发展得较差（OR=0.78，95%CI 0.63 至 0.96，p=0.016），对 TSSE 的自我效能感较低（OR=0.92，95%CI 0.86 至 0.99，p=0.028），而依从者。
在接受黑色素瘤治疗的人群中，每月进行 TSSE 的依从性可以分为依从、下降和不依从轨迹。在开始时收集关于参与 TSSE 的意图、抑郁、自我效能和/或行动计划的信息，可能有助于确定那些需要额外干预的人。
