Prospective Evaluation Of A Cognitive Vulnerability-Stress Model For Depression: The Interaction Of Schema Self-Structures And Negative Life Events., Pamela M Seeds, David J A Dozois

Psychology Publications

This study tested the diathesis-stress component of Beck's (1967) cognitive theory of depression. Initially, participants completed measures assessing cognitive organization of the self-schema and depressive symptoms. One year later, participants completed measures assessing cognitive organization of the self-schema, depressive symptoms, and negative life events. Hierarchical multiple regression analyses, controlling for initial depression, indicated that more tightly interconnected negative content was associated with greater elevations in depressive symptoms following the occurrence of life events. More diffusely interconnected positive content for interpersonal self-referent information also interacted with life events to predict depressive symptoms. Cognitive organization dimensions showed moderate to high stability across …

Somatic Symptom Overlap In Beck Depression Inventory-Ii Scores Following Myocardial Infarction., Brett D Thombs, Roy C Ziegelstein, Louise Pilote, David J A Dozois, Aaron T Beck, Keith S Dobson, Samantha Fuss, Peter De Jonge, Sherry L Grace, Donne E Stewart, Johan Ormel, Susan E Abbey

BACKGROUND: Depression measures that include somatic symptoms may inflate severity estimates among medically ill patients, including those with cardiovascular disease.

AIMS: To evaluate whether people receiving in-patient treatment following acute myocardial infarction (AMI) had higher somatic symptom scores on the Beck Depression Inventory-II (BDI-II) than a non-medically ill control group matched on cognitive/affective scores.

METHOD: Somatic scores on the BDI-II were compared between 209 patients admitted to hospital following an AMI and 209 psychiatry out-patients matched on gender, age and cognitive/affective scores, and between 366 post-AMI patients and 366 undergraduate students matched on gender and cognitive/affective scores.

RESULTS: Somatic symptoms …

Seasonal Hippocampal Plasticity In Food-Storing Birds., David F Sherry, Jennifer S Hoshooley

Psychology Publications

Both food-storing behaviour and the hippocampus change annually in food-storing birds. Food storing increases substantially in autumn and winter in chickadees and tits, jays and nutcrackers and nuthatches. The total size of the chickadee hippocampus increases in autumn and winter as does the rate of hippocampal neurogenesis. The hippocampus is necessary for accurate cache retrieval in food-storing birds and is much larger in food-storing birds than in non-storing passerines. It therefore seems probable that seasonal change in caching and seasonal change in the hippocampus are causally related. The peak in recruitment of new neurons into the hippocampus occurs before birds …
