后来的一项研究也对成年精神病人进行了进一步的支持，结果发现积极事件的归因是通过减少绝望的中介作用来预测抑郁症状减轻的(Johnson, Han, Douglas, Johannet， & Russell, 1998)。另一项选择直接调查康复模式的研究是Voelz、Haeffel、Joiner和Wagner(2003)对住院精神病儿童的研究。然而，与之前的研究不同的是，他们的研究还考虑了增强和消极认知风格对事件的相互作用，他们预期这些相互作用会对抑郁症的恢复产生影响。不幸的是，他们的研究未能发现这两种认知方式之间的相互作用，并不能像他们假设的那样，成为抑郁症症状减轻的预测因素。然而，他们确实发现，这两种认知方式都是无望结局的预测因素，这与恢复模型是一致的。他们的研究还发现，在整个样本中，对积极事件的认知风格提高程度越高的儿童，出院时的绝望程度越适中，无论他们对消极事件的认知风格有多低。这些结果为恢复模型提供了进一步的支持，因为增强对积极事件的认知风格似乎是缓冲绝望，这是已知的抑郁症的一个主要因素。然而，Voelz和他的同事(2003)也发现了与恢复模型有些违背直觉的现象。在整个样本中，他们发现那些对生活事件的积极和消极认知风格都很低的孩子是绝望感最低的.
A later study that was also done with the adult psychiatric patients further supported the recovery model, with results that found attributions of positive events to be a predictor of decreased depressive symptoms through the mediating role of decreased hopelessness (Johnson, Han, Douglas, Johannet, & Russell, 1998). Another study that also chose to directly investigate the recovery model was Voelz, Haeffel, Joiner, and Wagner (2003) study with inpatient psychiatric children. However, unlike previous studies, their study also wanted to take into account the interaction of both enhancing and negative cognitive styles for events and they anticipated that there would interactions effects on recovery to depression. Unfortunately, their study was unable to find the interaction of both cognitive styles as predictors of decreased depressive symptoms as they had hypothesized. They did, however, find that both cognitive styles were predictors of hopelessness outcomes which was consistent with the recovery model. Their study also found that within the entire sample, the children with higher levels of an enhancing cognitive style towards positive events had moderate levels of hopelessness upon discharge whether or not they had any level of a negative cognitive style towards negative events. These results served as further support of the recovery model as enhancing cognitive style towards positive events seemed to be buffer hopelessness which is known to be a major contributor towards depression. However, Voelz and his colleagues (2003) also had findings that were somewhat counterintuitive to the recovery model. Within the entire sample, they found that the children who had low levels of both a positive and negative cognitive style towards life events were the ones with the lowest level of hopelessness..
