Examining reward-seeking, negative self-beliefs and over-general autobiographical memory as mechanisms of change in classroom prevention programs for adolescent depression.

Background: Effective methods to prevent adolescent depressive symptoms could reduce suffering and burden across the lifespan. However, psychological interventions delivered to adolescents show efficacy only in symptomatic or high-risk youth. Targeting causal risk factors and assessing mechanistic change can help devise efficacious universal or classroom based prevention programs.

A longitudinal high-risk study of adolescent anxiety, depression and parent-severity on the developmental course of risk-adjustment.

Background: Adolescence is associated with developments in the reward system and increased rates of emotional disorders. Familial risk for depression may be associated with disruptions in the reward system. However, it is unclear how symptoms of depression and anxiety influence the development of reward-processing over adolescence and whether variation in the severity of parental depression is associated with hyposensitivity to reward in a high-risk sample.

A sense of embodiment is reflected in people's signature size.

Background: The size of a person's signature may reveal implicit information about how the self is perceived although this has not been closely examined.

Methods/results: We conducted three experiments to test whether increases in signature size can be induced. Specifically, the aim of these experiments was to test whether changes in signature size reflect a person's current implicit sense of embodiment.

A direct method of assessing underlying cognitive risk for adolescent depression.

An enduring tendency towards negative thinking is thought to increase vulnerability for future depression. However, it has not been possible to assess this tendency in non-depressed mood states. We examined if response latency to endorse dysfunctional attitudes is associated with depressive outcomes in a longitudinal study.

A longitudinal study of processes predicting the specificity of autobiographical memory in the adolescent offspring of depressed parents.

Deficits in specific autobiographical memory retrieval are closely associated with depression. The ability to retrieve specific autobiographical memories develops throughout childhood and adolescence and is associated with adolescent depression within and across time. Studying young samples before they first experience depression provides an approach for testing processes that underlie reduced autobiographical memory specificity.

Examining overgeneral autobiographical memory as a risk factor for adolescent depression.

Objective: Identifying risk factors for adolescent depression is an important research aim. Overgeneral autobiographical memory (OGM) is a feature of adolescent depression and a candidate cognitive risk factor for future depression. However, no study has ascertained whether OGM predicts the onset of adolescent depressive disorder.

Effects of analytical and experiential self-focus on stress-induced cognitive reactivity in eating disorder psychopathology.

Previous research suggests distinct modes of self-focus, each with distinct functional properties: Analytical self-focus appears maladaptive, with experiential self-focus having more adaptive effects on indices of cognitive-affective functioning (e.g., Watkins, Moberly, & Moulds, 2008).

Can basic risk research help in the prevention of childhood and adolescent depression? Examining a cognitive and emotional regulation approach.

This paper aims to highlight ways in which basic research findings in the field of childhood and adolescent depression can help to inform and refine preventive intervention efforts. We selectively review basic research evidence from community, clinical, and high-risk populations that identifies cognitive mechanisms (thought processes and reactions to negative affect) and emotional regulation as key processes involved in the onset and maintenance of depression. We focus on cognitive and emotional mechanisms in order to allow comparability with the majority of current preventive interventions.

Rumination, experiential avoidance, and dysfunctional thinking in eating disorders.

The majority of research in eating disorders (ED) has investigated the content of disorder-specific thoughts, while few studies have addressed underlying cognitive-affective processes. A better understanding of processes underpinning ED may have important implications for treatment development. Two studies were conducted that investigated levels of rumination, beliefs about rumination, experiential avoidance, and aspects of schematic thinking in individuals with eating pathology.

An exploratory study of cognitive style in performance on matched and mismatched tasks.

Researchers have suggested that task performance is often dependent upon the congruence of cognitive style and task. To explore this suggestion, 44 female and 4 male undergraduates were administered the Cognitive Style Analysis, the Closure Flexibility, the Composite Gestalt Completion Test, and the Vocabulary subtest from the WAIS. Specifically, four hypotheses were tested: (1) that participants with an analytic style will perform better than those with a wholistic style on the Closure Flexibility; (2) that participants with a wholistic style will perform better than those with an analytic style on the Composite Gestalt Completion Test; (3) that participants with an intermediate style will outperform persons with an analytic style on the Composite Gestalt Completion Test; and (4) that intermediate scorers would perform better than those with a wholistic style on Closure Flexibility.
