This study investigated the effect of a weight reduction diet on cognitive performance and psychological well-being among overweight women. A total of 42 women undertook a 12-week weight reduction diet while 21 women maintained their usual diet and exercise habits for 12 weeks.

BACKGROUND A growing body of research suggests that individuals with a history of multiple suicide attempts exhibit more severe psychopathology than individuals with only one or no previous suicide attempts. Given the strong link between diagnoses of major depression and suicide risk, our primary goal was to determine which specific depressive characteristics differentiate multiple attempters f...

The purpose of this study was to evaluate treatment specificity and potential mediators of two online therapies for depressive symptoms. We conducted a randomized controlled trial in which 263 participants were randomized to online cognitive behavioral therapy (CBT), online problem-solving therapy (PST) or a waiting list control group. Both treatments were more effective than the control group ...

Personality and psychopathology have long been associated, however the mechanisms that account for this link are less understood. Stress generation was examined as a potential mechanism to explain the association between personality traits, especially negative emotionality, and depressive symptoms. In addition, the moderating influence of cognitive vulnerabilities to potentiate the relation bet...

Two studies investigated a hypothesis of Dalgleish et al. (2003) that overgeneral memory may arise from matching between task cues and dysfunctional attitudes or schemas. In the first study, 111 euthymic patients with at least two previous major depressive episodes completed the Dysfunctional Attitude Scale: Form A (DAS-A) and the Autobiographical Memory Test (AMT). In the second study, 82 pati...

Three studies investigated the relation between adult attachment security and symptoms of depression. Study l examined the overall magnitude of the association between adult attachment and depression, and Studies 2 and 3 tested whether this relation was mediated by dysfunctional attitudes and low self-esteem. Results from the three studies were consistent with a mediation model. This model sugg...

Results from studies using a behavioral high-risk design and approximations to it generally have corroborated the cognitive vulnerability hypothesis of depression, whereas results from remitted depression studies typically have not. Suspecting that design features of previously conducted remitted designs likely precluded them from detecting maladaptive cognitive patterns, the authors conducted ...

This study examined the interaction of cognitive style (as assessed self-report and information-processing battery) and stressful life events in predicting the clinician-rated depressive and manic symptomatology of participants with Research Diagnostic Criteria lifetime diagnoses of bipolar disorder (n = 49), unipolar depression (n = 97), or no lifetime diagnosis (n = 23). Bipolar and unipolar ...
