Effect of Fordyce Happiness Model on depression, stress, anxiety, and fatigue in patients with multiple sclerosis.

Purpose: This study was conducted to investigate the effect of Fordyce Happiness Model (FHM) on depression, stress, anxiety, and fatigue in MS patients.

Methods: In this clinical trial, 140 MS patients assigned to experimental and control groups. Depression, anxiety, stress, and fatigue were measured by Depression Anxiety Stress Scale-21 and Piper Standard Scale before and immediately and three months after the implementation of FHM. The data were analyzed by SPSS 18.

Results: Independent t-test indicated that total scores of stress, depression, and fatigue of the two groups were not significantly different before the intervention but were significantly different after the intervention (P˂0.05). Moreover, anxiety scores of the two were not significantly different after the intervention (P˃0.05).

Conclusion: FHM can assist MS patients to manage their disease and associated problems in life. Besides that, since FHM is efficient and costless, it can be incorporated into the health interventions for MS patients.
