Text messages may sustain post-counseling gains in behavioral improvements and reduce HIV/STI incidence. However, their effectiveness may depend on the messages' time perspective and characteristics of the individual. We evaluated the impact of time perspective on a text messaging intervention designed to maintain improvements in safer sex practices among drug-using and non-drug-using female sex workers (FSWs) in Tijuana (n = 141) and Cd. Juarez (n = 129), Mexico. FSWs received the efficacious Mujer Segura intervention, and were randomized to receive safer sex maintenance text messages with either a short-term or future-oriented time perspective. The outcome was HIV/STI incidence rate over 6-month follow-up. In Tijuana, combined HIV/STI incidence density was lower among FSWs in the FUTURE group (31.67 per 100 py) compared to women in the SHORT-TERM group (62.40 per 100 py). Conversely, in Cd. Juarez, HIV/STI incidence density was lower (although non-significant) among FSWs in the SHORT-TERM group (19.80 per 100 py) compared to those in the FUTURE group (35.05 per 100 py). These findings suggest that future-oriented text messages may sustain post-counseling improvements in sexual risk behavior among FSWs, but findings may vary by FSWs' characteristics (e.g., drug use), and by region and context.
短信可能会维持咨询后的行为改善，并降低 HIV/性传播感染的发生率。然而，其效果可能取决于信息的时间视角和个体的特点。我们评估了时间视角对短信干预的影响，该干预旨在维持蒂华纳（n=141）和华雷斯城（n=129）墨西哥的吸毒和非吸毒女性性工作者（FSW）的安全性行为改善。FSW 接受了有效的 Mujer Segura 干预，并被随机分配接受具有短期或未来导向时间视角的安全性行为维持短信。结果是 6 个月随访期间的 HIV/性传播感染发生率。在蒂华纳，未来组的 FSW 中 HIV/性传播感染综合发生率密度（31.67 每 100 人年）低于短期组（62.40 每 100 人年）。相反，在华雷斯城，短期组的 FSW 中 HIV/性传播感染发生率密度（尽管不显著）较低（19.80 每 100 人年），而未来组的 HIV/性传播感染发生率密度较高（35.05 每 100 人年）。这些发现表明，未来导向的短信可能会维持咨询后 FSW 性风险行为的改善，但发现可能因 FSW 的特点（如吸毒）以及地区和背景而异。
