mHealth interventions have shown promise for helping people sustain healthy behaviors such as weight loss. However, few have assessed treatment fidelity, that is, the accurate delivery, receipt, and enactment of the intervention. Treatment fidelity is critical because the valid interpretation and translation of intervention studies depend on treatment fidelity assessments. We describe strategies used to assess treatment fidelity in mobile health (mHealth) interventions aimed at sustaining healthy behaviors in weight loss. We reviewed treatment fidelity recommendations for mHealth-based behavioral interventions and described how these recommendations were applied in three recent weight loss studies. We illustrate how treatment fidelity can be supported during study design, training of providers, treatment delivery, receipt of treatment, and enactment of treatment skills. Pre-planned strategies to ensure the treatment fidelity of mHealth interventions will help counter doubts concerning valid conclusions about their effectiveness and allow investigators and clinicians to implement robustly efficacious mobile health programs.

移动健康干预措施已显示出有助于人们维持健康行为（如减肥）的前景。然而，很少有研究评估治疗保真度，即干预措施的准确实施、接受和执行情况。治疗保真度至关重要，因为干预研究的有效解释和转化依赖于治疗保真度评估。我们描述了用于评估移动健康（mHealth）干预措施中治疗保真度的策略，这些干预措施旨在维持减肥过程中的健康行为。我们回顾了基于移动健康的行为干预措施的治疗保真度建议，并描述了这些建议在最近三项减肥研究中的应用情况。我们举例说明了在研究设计、提供者培训、治疗实施、治疗接受以及治疗技能执行过程中如何支持治疗保真度。预先制定的确保移动健康干预措施治疗保真度的策略将有助于消除对其有效性得出有效结论的疑虑，并使研究人员和临床医生能够实施强有力的有效移动健康计划。
