About this project
Shared infrastructure for SDT synthesis
MetaSDT is a living meta-analysis platform for self-determination theory, created in partnership with the Center for Self-Determination Theory. It will be perpetually updating so that it grows alongside the field. Data will be made publicly available soon, and the website will exist as open-science infrastructure.
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.
Basic needs ↔ wellbeing
Pooled effect sizes across 7,460 correlations, for the three needs as both satisfaction and frustration. Random-effects multilevel estimates (Fisher-z; effects nested in samples within studies), with 95% CIs. Hover any cell for full details.
