We explore changes in self-reported religious/spiritual identity in 313 African American adults over an average period of 2.5 years. Changes in religious and spiritual identity were reported by half of the participants and were associated with age, education, and income. The least stability was observed among respondents identifying as religious/not spiritual at baseline but shifting to religious and spiritual at follow-up. This trend was significant for respondents age 55 and over. Faith-based interventions for African Americans should consider viewing religious and spiritual identity as a fluid rather than fixed characteristic assessing changes in spiritual and religious attributes over time.
