目的：强光疗法治疗季节性情感障碍(SAD)已被广泛研究。然而，对亚综合征季节性情感障碍(SSAD)或在工作场所使用强光的关注很少。许多使用明亮灯箱的患者抱怨使用不便。这种不便很大程度上涉及通常建议的强光疗法的早期时机。已经有觉醒困难的患者，往往在醒来后不久就在上班前使用强光疗法有困难。如果在工作场所能够有效地使用强光，治疗将更加方便；改善的便利性可能会改善遵从性。方法：对30例亚综合征季节性情感障碍患者采用工作场所强光治疗，比较上午和下午的强光治疗效果。结果：早晚强光均能显著降低患者的抑郁评分，改善主观情绪、精力、警觉性和工作效率评分。而强光照射两次给药后，上述指标均无显著差异。两种强光治疗均耐受性良好。结论：在工作场所给予强光可以改善SSAD受试者的情绪、能量、警觉性和生产力的主观评分。上午和下午的强光导致了类似程度的改善。
Objective: Bright light therapy in seasonal affective disorder (SAD) has been studied extensively. However, little attention has been given to subsyndromal seasonal affective disorder (SSAD) or the use of bright light in the workplace. Many patients using bright light boxes complain of the inconvenience of use. Much of this inconvenience involves the often-recommended early timing of the bright light therapy. Patients, who already have difficulty awakening, often have difficulty using the bright light therapy soon after awakening before going to work. If bright light could be used effectively in the workplace, the treatment would be more convenient; the improved convenience would probably improve compliance. In this study, we studied the effectiveness of bright light therapy in subjects with SSAD in the workplace, comparing morning bright light with afternoon bright light.Method: Morning and afternoon bright light treatment (2500 lux) were compared in 30 subsyndromal seasonal affective disorder patients using the bright light therapy in the workplace. Hamilton Depression Ratings and subjective measures of mood, energy, alertness and productivity were assessed before and after 2 weeks of light therapy.Results: Both morning and evening bright light significantly decreased the depression ratings and improved the subjective mood, energy, alertness and productivity scores. However, there were no significant differences between the two times of administration of the bright light treatment. Both bright light treatments were well tolerated.Conclusion: Bright light given in the workplace improves subjective ratings of mood, energy, alertness and productivity in SSAD subjects. Morning and afternoon bright lights resulted in similar levels of improvement.
