Pre-Experiment.

Background
We aimed to explore the influence of solution-focused approach (SFA) on anxiety and depression, sleep quality, quality of life and clinical pregnancy rate among women aged 35 or over undergoing in vitro fertilization-embryo transfer (IVF-ET).
Methods
The study was performed at the reproductive center in a public hospital in Lanzhou city. Totally, 112 women were enrolled in this study, and were divided into group SFA (n = 56) and group control (n = 56). The patients in the group SFA completed five sessions (30 minutes/turn), and patients in the group control received routine care.
Results
The intervention group showed a significant decrease in anxiety (t =  11.906, P <  0.001) and depression scores (t =  14.991, P <  0.001), as well as PSQI scores (t =  7.055, P <  0.001), and increased FertiQoL scores (t =  -2.828, P <  0.001). Comparing the two groups after the intervention, the intervention group demonstrated significantly lower SAS scores (t =  -10.348, P <  0.001), SDS scores (t =  -8.416, P <  0.001), and PSQI scores (t =  -5.087, P <  0.001), while FertiQoL scores were higher than the control group (t =  2.389, P =  0.019). The intervention group reported a satisfaction rate of 96.2% to 100% with the SFA.
Conclusions
SFA can help relieve anxiety and depression, improve sleep quality and reproductive life quality. Improvement in psychological distress might not contribute to increasing female fecundity. Patients in the group SFA were satisfied with the intervention.
