Summary
The Fatigue Severity Scale (FSS) reliably measures fatigue in obese women undergoing weight loss treatment. The scale demonstrated high reliability, confirming its utility in obesity research and treatment programs.
Area of Science:
- Obesity research
- Clinical psychology
- Health psychology
Background:
- The Fatigue Severity Scale (FSS) is a validated self-report measure for assessing fatigue.
- Historically normed on multiple sclerosis patients, FSS has been applied to conditions like obstructive sleep apnea and in exercise studies.
- Obesity is often associated with increased fatigue, impacting daily functioning.
Purpose of the Study:
- To evaluate the utility and reliability of the Fatigue Severity Scale (FSS) in obese individuals.
- To assess the impact of a 16-week obesity treatment program on fatigue levels using the FSS.
- To determine the FSS's pre- and post-test reliability within this specific population.
Main Methods:
- A cohort of 118 obese females (average age 45.24) participated in a 16-week obesity treatment program.
- The Fatigue Severity Scale (FSS) was administered before and after the intervention period.
- Statistical analysis focused on the reliability of FSS scores and correlation with weight loss outcomes.
Main Results:
- The Fatigue Severity Scale (FSS) demonstrated high pre- and post-test reliability in obese females.
- Significant weight loss was observed in the participants following the 16-week program.
- The FSS effectively captured changes in fatigue levels related to the obesity treatment.
Conclusions:
- The Fatigue Severity Scale (FSS) is a reliable instrument for assessing fatigue in obese women.
- The FSS can be effectively utilized in obesity treatment research and clinical practice.
- Fatigue levels in obese individuals may be influenced by weight management interventions.
