Relationship discord is associated with the severity, onset, and course of depression. Consequently, including partner depressed individuals in treatment may be expected to beneficial In this article, we review existing research on couple-based interventions for depression, specifically developed couples experiencing co-occurring depression relationship discord, as well who are not necessarily discordant. We also change processes mediators outcome, predictors outcome. Couple-based have been...

This study examined the extent to which rumination and depression share genetic environmental influences in a community sample of adult twins (N = 663). Twins completed multiple questionnaires, depressive symptoms questionnaire diagnostic interview. Rumination was moderately heritable (h2 .37–.41 for latent variable) substantially influenced by nonshared factors, these results were consistent across different measures. Nonshared on larger women than men. Depressive diagnosis factors...

The current study investigated whether trait anxiety was systematically related to task-set shifting performance, using a task-switching paradigm in which 1 task more attentionally demanding than the other. Specifically, taking advantage of well-established phenomenon known as asymmetric switch costs, we tested hypothesis that association between and is most clearly observed when individuals must away from for it necessary effortfully establish an appropriate set.

Participants ( N = 457 twin pairs) completed measures of events annually from ages 9 16. The same factors influenced across time increased in magnitude during the transition adolescence. Independent were less genetically than boys, but not girls. Shared decreased as youth transitioned into Nonshared mostly age...

We examined the magnitude of genetic and environmental influences on observed negative emotionality at age 14, 20, 24 months. Participants were 403 same-sex twin pairs recruited from Longitudinal Twin Study whose emotional responses to four different situations coded by independent raters. Negative showed significant consistency across settings, there was evidence a latent underlying construct.

Abstract Panic search occurs when the presentation of a fearful facial expression precue, prior to display, improves target detection relative neutral and positive expressions are used. In present study, acted as precues targets were images either or threatening animals. It was predicted that image following precue would be particularly facilitated. first experiment, better than neutral, but cue enhancement did not occur. second type blocked, participants facilitated in responding precues....
