Effect of group motivational interviewing method versus feedback-oriented training method on fatigue and self-efficacy of patients with cancer undergoing chemotherapy: a randomized clinical trial

To assess the effect of group motivational interviewing method versus feedback-oriented training method on fatigue and self-efficacy of patients with cancer undergoing chemotherapy

This is a randomized clinical trial with control group, phase III, in which 96 eligible patients with cancer undergoing chemotherapy will be randomly assigned through the block randomization to the intervention and control groups

This study will be performed in the Beheshti Hospital in Hamadan city on 96 eligible patients with cancer undergoing chemotherapy. The patients will be randomly assigned to the intervention and control groups through the block randomization. Blinding is not possible in this study.

Inclusion criteria: Age 18 to 60 years Having a cancer undergoing chemotherapy Persian language Ability to make phone calls Information about his/her illness Receiving at least three chemotherapy courses Exclusion criteria: Impaired consciousness or dementia Mental disorder Severe anemia Malnutrition

Intervention group 1: Routine treatment plus a motivational interview for 45 to 60 minutes once a week for 5 weeks (including teaching and practicing the stages of change, brainstorming about the strengths and weaknesses of behavior and its relationship with fatigue and self-efficacy reduction, identifying and prioritizing values, providing recommendations to improve fatigue) Intervention group 2: Routine treatment plus feedback-oriented training for 45 to 60 minutes once a week for 5 weeks (including explanations about cancer and its common treatments, explaining the side effects of drugs, the effect of fatigue on life, improving nutritional status, improving sleep quality) Control group: Just routine treatment

Primary outcome: Fatigue; self-efficacy

The patients will be randomly assigned to intervention and control groups using block randomization. For this purpose, we will prepare six sheets of paper, writing on two sheets the name of the intervention 1 and on two other sheets the name of the intervention 2 and on the third two sheets the name of the control. The paper sheets will be pooled, placed in a container, and randomly drawn one at a time for each patient without replacement until all six sheets are drawn. The six paper sheets will be then placed back into the container, and this action repeated until the sample size is reached.
