Entrapment and Perceived Status in Graduate Students Experiencing a Recurrence of Major Depression

The present study used a prospective design to test the role of involuntary subordination as a predictor of major depression. Involuntary subordination is a construct derived from social rank theory and has been implicated as a cause of major depression. Its most salient features include feelings of entrapment and unfavourable social comparisons (i.e., low perceived status). An initial sample of 146 graduate students underwent a diagnostic interview to confirm a history of major depression and also completed measures of entrapment and social comparison. After 16 months, participants were assessed for a recurrence of major depression. Participants who experienced a recurrence of depression had significantly higher levels of involuntary subordination (as measured by factor scores of entrapment and social comparison). A logistic regression analysis also showed that involuntary subordination predicted recurrence of depression, even when controlling for current major depression and the number of previous episodes. The present study demonstrates the advantages of adopting a social rank perspective in modeling major depression.
