Design outcomes
Primary
| Measure | Time frame |

| Expected outcome 1: The intervention was expected to improve psychological well-being;Outcome found 1: An improvement in psychological well-being was observed, using the Goldberg General Health Questionnaire (GHQ) and the Positive and Negative Affect Scale (PANAS) psychological protocols, although these did not show statistical significance;Expected outcomes 6: The study aimed to evaluate the influence of inhaling Citrus sinensis (L.) Osbeck essential oil (high limonene content) and Citrus aurantium Lineu essential oil (high linalool and linalyl acetate content) on the psychobiological, psychopharmacological, and psychological profile, and on symptoms related to anxiety, stress, and depression, in human volunteers after 12 months of study | — |

| Expected outcomes 7: The results of biochemical analyses were expected for the parameters melatonin, ghrelin, serotonin, chromogranin A (CgA), testosterone, prolactin, growth hormone (GH), adrenocorticotropin (ACTH), and neuropeptide K (NPK);Outcome found 7: The parameters melatonin, ghrelin, and serotonin were analyzed; however, the equipment readings fell below the sensitivity limit, so these parameters were not included in the manuscript. The parameters chromogranin A (Cg A), testosterone, prolactin, growth hormone (GH), adrenocorticotropin (ACTH), and neuropeptide K (NPK) could not be analyzed due to a lack of analysis kit for the equipment and insufficient saliva sample volume to perform the analysis;Expected outcomes 2: The intervention was expected to reduce anxiety symptoms;Outcome found 2: A decrease in anxiety symptoms was observed, using the Beck Anxiety Inventory (BAI), State-Trait Anxiety Inventory (STAI) psychological protocols and biochemical analyses of Dopamine and Leptin. The results of the State-Trait Anxiety Inventory (STAI) and Leptin showed statistical significance;Expected outcomes 3: The intervention was expected to reduce stress symptoms;Outcome found 3: A decrease in stress symptoms was observed, using the Lipp Stress Symptom Inventory for Adults (ISSL) psychological protocol and Cortisol biochemical analysis. The results of the Lipp Stress Symptom Inventory for Adults (ISSL) showed statistical significance;Expected outcomes 4 The intervention was expected to reduce symptoms of depression;Outcome found 4: A decrease in depression symptoms was found, as measured by the Beck Depression Inventory (BDI) and biochemical analysis of Dopamine, although these did not show statistical significance;Expected outcomes 5: The intervention was expected to strengthen the immune system;Outcome found 5: Strengthening of the immune system was found, through biochemical analyses of interleukins IL-2, IL-6, IL-10, TNF-alpha, and Leptin.
