Description

The Modified Fatigue Impact Scale (MFIS) is a tool used to assess the impact of fatigue on an individual’s functionality and quality of life. It is a modified version of the Fatigue Impact Scale (FIS), designed to better evaluate fatigue in various clinical conditions such as multiple sclerosis (MS), chronic illnesses, and psychological disorders.

Analysis

The MFIS evaluates fatigue across three key domains:
Physical Functioning: Assesses how fatigue affects physical capacity and daily functioning.
Cognitive Functioning: Measures the impact of fatigue on cognitive performance, including issues with concentration and memory.
Social and Emotional Functioning: Evaluates how fatigue affects social interactions and emotional well-being.

Objective

The main goals of the Modified Fatigue Impact Scale (MFIS) are:
Fatigue Assessment: To provide a comprehensive evaluation of fatigue and its effects on different aspects of an individual’s life.
Monitoring Changes: To track the progression of fatigue and the effectiveness of therapeutic interventions.
Diagnosis and Treatment Planning: To aid in diagnosing fatigue-related issues and in developing treatment strategies to manage fatigue.

Scoring

The scoring process for the MFIS includes:
Questionnaire Completion: The patient or individual fills out a questionnaire that includes items related to fatigue and its impact on their life.
Response Analysis: Responses are analyzed to determine the level of fatigue and which areas of functioning are affected.
Scores and Interpretation: Total scores are calculated for each domain and for overall fatigue, providing a clear picture of how fatigue affects the individual.
