What researchers measure

Primary outcomes

  1. Change in fatigue level assessed by the Multidimensional Fatigue Inventory (MFI-20)

    Fatigue level will be assessed using the Multidimensional Fatigue Inventory (MFI-20), a validated self-report questionnaire. Prior to the initiation of the aromatherapy intervention, baseline MFI-20 data will be collected through face-to-face interviews conducted by Assessor 1. Following the completion of the four-week intervention period, the MFI-20 will be re-administered through face-to-face interviews by Assessor 2. The primary outcome will be the mean change in total MFI-20 score from baseline to post-intervention. Comparisons will be conducted between the intervention groups and the placebo control group.

    Time frame: Baseline and at the end of the 4-week intervention period

  2. Change in insomnia complaints and sleep quality assessed by the Basic Insomnia and Sleep Quality Scale (BaSIQS)

    Insomnia complaints and sleep quality will be assessed using the Basic Insomnia and Sleep Quality Scale (BaSIQS), a validated self-report questionnaire. Baseline measurements will be collected through face-to-face interviews conducted by Assessor 1 prior to the initiation of the aromatherapy intervention. Following the completion of the four-week intervention period, the BaSIQS will be re-administered through face-to-face interviews by Assessor 2. The primary outcome will be the mean change in total BaSIQS score from baseline to post-intervention. Comparisons will be made between the aromatherapy intervention groups and the placebo control group.

    Time frame: Baseline and at the end of the 4-week intervention period

Secondary outcomes

  1. Change in quality of life assessed by the Older People's Quality of Life Questionnaire-Brief (OPQOL-Brief)

    Quality of life will be assessed using the Older People's Quality of Life Questionnaire-Brief (OPQOL-Brief), a validated self-report instrument. Baseline measurements will be collected through face-to-face interviews conducted by Assessor 1 prior to the initiation of the aromatherapy intervention. Following the completion of the four-week intervention period, the OPQOL-Brief will be re-administered through face-to-face interviews by Assessor 2. The primary outcome will be the mean change in total OPQOL-Brief score from baseline to post-intervention. Comparisons will be made between the aromatherapy intervention groups and the placebo control group.

    Time frame: Baseline and at the end of the 4-week intervention period
