CONTEXT: Sleep issues are prevalent and affect health and well-being. The aspects of well-being that are impacted by sleep interventions have not been well studied.
OBJECTIVES: To investigate the impact of lavender and sleep hygiene (LSH) compared to sleep hygiene (SH) alone on well-being as measured by the Self-assessment of Change questionnaire (SAC) at post-intervention and two-week follow-up, and secondarily to compare the SAC sleep item to results from standardized sleep surveys.
DESIGN: Secondary analysis of a randomized controlled trial (RCT) where one group received a lavender inhalation patch and practiced sleep hygiene (LSH) and the other group received a placebo inhalation patch and practiced sleep hygiene (SH) for five consecutive nights.
SETTING: Usual sleep setting.
PARTICIPANTS: Seventy-nine college students with self-reported sleep issues.
MAIN OUTCOME MEASURES: The SAC was completed at post-intervention and follow-up.
RESULTS: Exploratory analysis showed significantly improved well-being for the LSH group at post-intervention for well-being domains of sleep, energy, and vibrancy (P = .01, .03, and .05, respectively) and an overall trend of improved well-being in comparison to the SH group at post-intervention and follow-up. The SAC sleep item showed a similar pattern of change to the standardized sleep surveys with a statistically significant improvement in sleep for the LSH group at follow-up (P = .02).
CONCLUSIONS: Findings demonstrate the positive impact of the lavender intervention on three domains of self-assessed well-being are energy, vibrancy, and sleep. SAC results extend and complement prior findings of improved sleep quality.
