One hundred and nine tinnitus sufferers attending a specialist out-patient clinic completed questionnaires assessing the following: locus of control of behaviour, anxiety (STAI), depression (BDI) and tinnitus severity. Anxiety and depression were found to be correlated with tinnitus severity, as was locus of control, with "internals" reporting their tinnitus to be less severe than "externals." Partial correlations indicated that locus of control did not directly affect tinnitus severity, but rather, this effect was mediated by the effect of locus of control on anxiety and depression.
109名前往专科门诊就诊的耳鸣患者完成了问卷调查，评估内容如下：行为的控制点、焦虑（状态-特质焦虑量表）、抑郁（贝克抑郁量表）和耳鸣严重程度。研究发现，焦虑和抑郁与耳鸣严重程度相关，控制点也与之相关，“内控者”报告其耳鸣严重程度低于“外控者”。偏相关分析表明，控制点并未直接影响耳鸣严重程度，而是通过控制点对焦虑和抑郁的影响起到中介作用。
