    Input: Dynamic systems theory provides a conceptual framework for the study of change in psychotherapy that is consistent with that used in other sciences . A dynamic systems model of change was proposed and evaluated in the context of cognitive therapy for depression . Consistent with this model , less client protection and more destabilization of depressive patterns  predicted more improvement at the end of treatment . Less protection was associated with more therapist support/stabilization . More destabilization was associated with more affective intensity in the session and with more of a therapist focus on the historical antecedents of current problems , exposure to multiple sources of corrective information , and repeated practice of new skills . Although preliminary , this pattern of findings is consistent with the model proposed and with principles of dynamic systems from other sciences I. H. Gotlib and C.L. Hammen 's ( 1992 ) psychopathology model of depression was used as a conceptual framework for study ing the process of change in an effective course of cognitive therapy ( CT ) for depression . Archived CT transcripts from 30 depressed out patients in the Cognitive-Pharmaco-therapy Treatment project ( S. D. Hollon et al. , 1992 ) were studied . An observational coding system was used to assess whether therapists focused on the cognitive , interpersonal , and developmental vulnerabilities of depression and whether these interventions were associated with symptom reduction . Therapists maintained a primarily cognitive focus , but it was interventions that addressed the interpersonal and developmental domains that were associated with improvement . A developmental focus also predicted a longer time of recovery and better global functioning over the 24-month followup period . These findings are consistent with recent theoretical developments in cognitive therapy and with the psychopathology research on depression 
    Output:
    
The 10 included articles showed that supportive and exploratory statements and addressing aspects in the therapeutic relationship were perceived as positive regarding symptom outcome .
Negative effects were particularly evident with controlling and challenging statements of the therapist .
Regarding the therapeutic alliance , both positive and negative as well as nonsignificant results were obtained .
