Objective.
To investigate the effects of bright light treatment for secondary outcome measures and to explore and validate empirically derived subgroups and treatment effects in subgroups.
Methods.
A descriptive design.
A sample of forty-nine persons (mean age of 45.8) with clinically assessed seasonal affective disorder (SAD) or subsyndromal SAD (S-SAD) participated in a two-group clinical trial evaluating the effects of treatment with bright light therapy.
A person-oriented cluster analysis was applied to study treatment effects in subgroups.
Results.
For the merged group, sleepiness (Epworth Sleepiness Scale), fatigue (fatigue questionnaire), and health-related quality of life (SF-36) were improved at posttreatment, and results were maintained at the one-month followup.
Three distinct subgroups had a high level of fatigue in common, while the level of excessive daytime sleepiness and depressed mood differed between the subgroups.
Over time, all subgroups improved following ten days treatment in a light room.
Conclusion.
Fatigue, excessive daytime sleepiness, and health-related quality of life improve in a similar way as depressed mood following treatment with bright light.
The treatment was effective irrespective of the severity of the disorder, that is, for persons with SAD and subsyndromal SAD.
