About this project

Shared infrastructure for SDT synthesis

MetaSDT is a living meta-analysis platform for self-determination theory. It is a perpetually updating, open-science infrastructure designed to host SDT synthesis in a single citable source. This shared infrastructure is designed to grow with the field.

The platform is organised into data modules each representing systematic reviews. The current version contains a comprehensive systematic review of basic psychological needs research, and is supported with data from prior published meta-analyses on autonomy support, aspirations, and regulation types (Bradshaw et al., 2023; Bureau et al., 2022; Howard et al., 2017, 2021, 2024; Slemp et al., 2018, 2024; Van den Broeck et al., 2021).

Comprehensive systematic coverage of the remaining SDT literature is planned.
