Used a measure of reduction in experienced control to investigate two aspects of the learned helplessness model of depression. Consistent with this model, psychiatric inpatients who reported reduced control over life events prior to hospitalization were significantly more depressed than individuals who reported no such reductions. Locus of control (IE) was not related to depression scores, and it was suggested, in light of previous research, that future research on the antecedents of depression employ more specific measures of control rather than measures of generalized expectancies. Additionally, depressive as a diagnostic group reported greated reduced control than chronic schizophrenics, paranoid schizophrenics, and patients with personality disorder diagnoses. These results were interpreted as supporting the specificity of learned helplessness to depression. It was suggested that research on learned helplessness and depression, which has relied on college student analogues, can be complemented profitably by studies of reduced experience control within clinical populations.
采用经验性控制降低的测量方法来研究抑郁习得性无助模型的两个方面。与该模型一致,报告称住院前对生活事件控制降低的精神科住院患者比未报告此类降低的个体明显更抑郁。控制点(内控/外控)与抑郁得分无关,并且根据先前的研究表明,未来关于抑郁先兆的研究应采用更具体的控制测量方法,而非广义预期的测量方法。此外,作为一个诊断组,抑郁症患者报告的控制降低程度大于慢性精神分裂症患者、偏执型精神分裂症患者和人格障碍诊断患者。这些结果被解释为支持习得性无助对抑郁症的特异性。有人认为,依赖大学生类似情况的习得性无助和抑郁症研究,可以通过对临床人群中经验性控制降低的研究得到有益补充。
