In a follow-up study (first investigation: KIRSCHBAUM u. GISTL, arch. Psychol. 1973, 125, 263-273) fifteen patients with psychiatric or neurological disorders were examined for correlations between anxiety (clinical rating), scores from MAS and MMQ, and EEG-Alpha-percentage alterations during an unspecific relaxation training with or without Alpha-Biofeedback. Clinically and psychometrically high anxious patients (n = 10) showed under both conditions significant diminuation of Alpha-percentage in contrast to earlier examined students whose Alpha-rates had increased (significantly). Theoretical explanations of these results are discussed.
在一项后续研究中（首次调查：基尔希鲍姆和吉斯特尔，《心理学文献》，1973年，第125卷，第263 - 273页），对15名患有精神或神经疾病的患者进行了检查，以探究在进行有或没有α波生物反馈的非特异性放松训练期间，焦虑（临床评定）、MAS和MMQ得分与脑电图α波百分比变化之间的相关性。临床和心理测量显示为高焦虑的患者（n = 10）在两种情况下α波百分比均显著降低，这与早期检查的学生不同，那些学生的α波率（显著）增加。对这些结果的理论解释进行了讨论。
