Objective:

To examine the longitudinal associations of resting heart rate (RHR) and heart rate variability (HRV) with self-reported stress, anxiety, and depressive symptoms among individuals in substance use disorder (SUD) treatment.

Approach:

Key Findings:

• 39% of participants with decreased RHR reported decreased stress.
• 42% of participants with decreased RHR reported decreased anxiety.
• 39% of participants with decreased RHR reported improved depressive symptoms.
• 39% of participants with increased HRV reported decreased stress.
• 39% of participants with increased HRV reported improved anxiety.
• 41% of participants with increased HRV reported reduced depressive symptoms.

Interpretation:

Changes in physiological and mental health metrics during the first month of treatment varied among participants, indicating the need for integrated monitoring.

Limitations:

• Small sample size (N = 59) may limit generalizability.
• Short duration of monitoring (first month of treatment) may not capture long-term trends.

Conclusion:

The study highlights the importance of integrating physiological measures with self-reported mental health assessments to better understand changes during SUD treatment.
