The effect of progressive relaxation exercises on treatment-related symptoms and self-efficacy in patients with lung cancer receiving chemotherapy

Patients with lung cancer receiving chemotherapy experience many symptoms, simultaneously or separately, that limit their daily living activities. This study aimed to determine the effect of progressive relaxation exercises on treatment-related symptoms and self-efficacy in patients with lung cancer receiving chemotherapy. This randomized controlled experimental study was conducted in a university hospital chemotherapy outpatient clinic in Turkey. The study sample consisted of 84 patients, randomly allocated to an experimental group (n = 42) and a control group (n = 42). The experimental group received applied training in progressive relaxation exercises using an MP3 player. The control group received only standard nursing interventions in the chemotherapy unit. Data were collected from patients using a personal information form, a telephone counseling follow-up form, the Memorial Symptom Assessment Scale and the Strategies Used by People to Promote Health Scale. Data collection tools were administered at four different times (at first interview and three times on the seventh day of the end of the chemotherapy cycle) and weekly telephone follow-ups were performed. The symptom scores (frequency, severity and level of distress) significantly decreased in the experimental group, compared with the control group (p = 0.0001). Similarly, self-efficacy scores significantly improved in the experimental group (p = 0.001). Progressive relaxation exercises were potentially effective in promoting symptom management and improving the level of self-efficacy.
