Test whether three mediating processes of Self-Determination Theory are involved in intervention effects on quality of life for breast cancer patients.
A randomized clinical trial recruited newly diagnosed breast cancer patients for 6 months of (1) Internet training and access, (2) access to an integrated eHealth system for breast cancer (CHESS), (3) a series of phone conversations with a Human Cancer Information Mentor, or (4) both (2) and (3).
This paper reports results after the initial 6 weeks of intervention, at which point patients in the combined condition had higher quality of life scores than those in the other three conditions. All three Self-Determination Theory constructs (autonomy, competence, and relatedness) mediated that effect as hypothesized. In addition, the single-intervention groups were superior to the Internet-only group on relatedness, though perhaps this was too soon for that to carry through to quality of life as well.
The SDT constructs do mediate these interventions' effects.
Intervention design can profitably focus on enhancing autonomy, competence and relatedness.
检验自我决定理论的三个中介过程是否参与了乳腺癌患者生活质量干预的效果。
一项随机临床试验招募了新诊断的乳腺癌患者，进行 6 个月的（1）互联网培训和访问，（2）访问综合电子健康系统（CHESS），（3）与人类癌症信息导师进行一系列电话交谈，或（4）同时（2）和（3）。
本文报告了干预最初 6 周后的结果，此时联合组的患者生活质量评分高于其他三组。所有三个自我决定理论结构（自主性、能力和关联性）都如假设的那样介导了这种影响。此外，单一干预组在关联性方面优于仅互联网组，尽管这可能为时过早，无法对生活质量产生同样的影响。
SDT 结构确实介导了这些干预的效果。
干预设计可以从增强自主性、能力和关联性方面受益。
