The use of four-point physical restraints on a single occasion or repeatedly in psychiatric inpatients was followed prospectively during 1993 in Beer Sheva Mental Health Center. Mood-disordered patients had significantly more restraints per patient than did schizophrenic and schizoaffective patients. The monthly rates of restraints of mood-disordered and schizophrenic patients were found to be negatively correlated with the duration of the daily photoperiod, which was phase-advanced by a month. The findings suggest that seasonality (the duration of the daily photoperiod) should be taken into account in attempts to predict the potential dangerousness of psychiatric patients.
1993年，贝尔谢巴精神卫生中心对精神科住院患者单次或多次使用四点身体约束进行了前瞻性跟踪研究。与精神分裂症和分裂情感性障碍患者相比，心境障碍患者人均受约束的次数明显更多。研究发现，心境障碍患者和精神分裂症患者的每月约束率与每日光照期时长呈负相关，而每日光照期时长提前了一个月。研究结果表明，在试图预测精神科患者的潜在危险性时，应考虑季节性因素（每日光照期时长）。
