Baseline Recovery Capital and Substance Use History as Determinants of Recovery Residence Length of Stay

Plain-Language Summary

How long someone stays in a recovery residence matters, because longer stays are consistently linked to better outcomes. This study asked what can be known on day one about who is likely to stay and who is at risk of leaving early. Drawing on data from 2,534 residents across 61 recovery residences in the United States between 2019 and 2023, the researchers examined how recovery capital, substance use history, and personal circumstances at admission related to length of stay. Residents who were older, reported higher quality of life, participated more in recovery groups, or had criminal legal system involvement tended to stay longer. Residents with a history of cannabis use, drug use in the 90 days before admission, or an unmet drug treatment need tended to leave sooner.

The analysis also identified nine distinct groups of residents with median stays ranging from 29 to 91 days. The groups who left earliest carried lower recovery capital, more unmet service needs, and more recent substance use, while the longest-staying groups showed higher quality of life and stronger engagement with support structures. The practical message: people arriving with recent drug use or unmet treatment needs may benefit from proactive support in their very first days, while peer engagement and structured support pathways help extend stays. The authors are careful to note that these patterns should shape adaptive, equity-conscious services, not be used to label individual residents as risks.
