<jats:title>Abstract</jats:title><jats:sec><jats:title>Objective</jats:title><jats:p>Research has shown that rumination and negative affect are elevated in patients with anorexia nervosa (AN), but the underlying origins remain unclear. Drawing from the theoretical framework of the Goal Progress Theory of rumination, we propose that heightened feelings of “inefficiency” (i.e., low self‐efficacy) in AN might play an important role in these dysfunctional cognitive‐affective processes.</jats:p></jats:sec><jats:sec><jats:title>Method</jats:title><jats:p>Thirty‐two weight‐recovered participants with a history of AN and 32 healthy control participants filled out questionnaires regarding rumination and affect six times a day over a period of 2 weeks via ecological momentary assessment in real‐life.</jats:p></jats:sec><jats:sec><jats:title>Results</jats:title><jats:p>Analyses via hierarchical as well as conceptual process modeling suggest that while inefficiency is generally associated with more rumination and negative affect, additional amplifying mechanisms between these variables exist specifically in recovered participants with a history of AN.</jats:p></jats:sec><jats:sec><jats:title>Discussion</jats:title><jats:p>Inefficiency as a core aspect of AN appears to trigger dysfunctional cognitive‐affective processes which may contribute to vulnerability for AN.</jats:p></jats:sec>
