Changes in Cognitive Errors Over the Course of Cognitive Therapy for Depression

What Do People Really Think of Me? Evaluating Bias in Interpersonal Predictions Over the Course of Cognitive-Behavioral Therapy of Depression

Cognitive behavioral therapy (CBT) of depression is hypothesized to achieve its effects by correcting negative biases. However, little research has tested how biases change over the course of CBT. We focus on biases in interpersonal judgments and examine whether changes in biases occur in CBT and are associated with symptom improvements. A sample of 126 adults (60% women, mean age 31.7, 83% White) participated in CBT of depression. Observers provided ratings of patients participating in two interpersonal tasks on three occasions. Patients were asked to predict observers' ratings. In a thin slice (TS) task, observers evaluated how patients came across in a brief segment in which patients talked about themselves. In a Standard Interaction Task (SIT), observers rated the social skills patients displayed in challenging role plays. The difference between patient predictions and observer ratings provided measures of bias in these interpersonal judgments. TS and SIT bias became significantly less pessimistic and more realistic over the course of CBT. Improvements in TS bias were associated with a faster reduction in symptoms, whereas there was a non-significant trend for improvement in SIT bias being associated with faster symptom reduction. Consistent with the CBT model, negative interpersonal biases became more realistic throughout a course of CBT for depression and at least some of the changes in bias were related to therapeutic outcomes. We encourage future researchers to continue examining for whom and under which conditions correcting such biases produces the greatest benefits.

Hoarding among older people: an evaluative review

While there is considerable evidence that the factors involved in hoarding typically begin to manifest early in life (mostly in adolescence), the majority of those sampled in research studies are in their later years. As so much of our understanding of the psychological factors involved in hoarding is derived from those who are older and more chronically affected, the core hoarding psychopathology may have been masked, overlaid or even disregarded in previous research and in our approaches to clinical intervention. That is, factors relating primarily to chronicity of the problem and feelings of demoralization, hopelessness, loss and the extent of the damage caused to the person's life may swamp the processes which led to and maintain the problem. The present review examines the extent to which this is so and considers theoretical and clinical implications. The literature relevant to hoarding in later life was reviewed evaluatively in relation to a number of questions placing hoarding in a lifespan developmental context. Many studies relied on purely descriptive methodologies, meaning that typical case presentations and case histories are well documented, with less attention paid to underlying causal and maintaining mechanisms. Efforts to identify and control for factors relating to age or problem chronicity were minimal. A key future direction is the identification of younger samples of people who hoard in order to identify more clearly the processes which drive acquisition and retention of excessive amounts of material.
