Substantial evidence suggests that rumination is an important vulnerability factor for adolescent depression. Despite this, few studies have examined environmental risk factors that might lead to rumination and, subsequently, depression in adolescence. This study examined the hypothesis that an adverse family environment is a risk factor for rumination, such that the tendency to ruminate mediates the longitudinal association between a negative family environment and adolescent depressive symptoms. It also investigated adolescent gender as a moderator of the relationship between family environment and adolescent rumination. Participants were 163 mother-adolescent dyads. Adolescents provided self-reports of depressive symptoms and rumination across three waves of data collection (approximately at ages 12, 15, and 17 years). Family environment was measured via observational assessment of the frequency of positive and aggressive parenting behaviors during laboratory-based interactions completed by mother-adolescent dyads, collected during the first wave. A bootstrap analysis revealed a significant indirect effect of low levels of positive maternal behavior on adolescent depressive symptoms via adolescent rumination, suggesting that rumination might mediate the relationship between low levels of positive maternal behavior and depressive symptoms for girls. This study highlights the importance of positive parenting behaviors as a possible protective factor against the development of adolescent rumination and, subsequently, depressive symptoms. One effective preventive approach to improving adolescent mental health may be providing parents with psychoeducation concerning the importance of pleasant and affirming interactions with their children.

Despite considerable past interest in distinguishing the patterns of attentional bias that characterise vulnerability to anxiety and to depression, little research has yet sought to delineate the attentional correlates of two affective dimensions that differentially contribute to these alternative forms of emotional vulnerability—negative and positive affectivity. In the present study, we employ a novel variant of the attentional probe task to examine selective attentional engagement with, and disengagement from, negative words, in participants whose heightened emotional vulnerability reflects either elevated negative affectivity, or attenuated positive affectivity. Elevated negative affectivity was found to be associated with both increased attentional engagement with, and impaired attentional disengagement from, negative information, especially when this was anxiety relevant. In contrast, attenuated positive affectivity was associated with facilitated attentional disengagement from negative information,...

Research in healthy controls has found that mood influences cognitive processing via level of action identification: happy moods are associated with global and abstract processing; sad moods are associated with local and concrete processing. However, this pattern seems inconsistent with the high level of abstract processing observed in depressed patients, leading Watkins (2008, 2010) to hypothesise that the association between mood and level of goal/action identification is impaired in depression. We tested this hypothesis by measuring level of identification on the Behavioural Identification Form after happy and sad mood inductions in never-depressed controls and currently depressed patients. Participants used increasingly concrete action identifications as they became sadder and less happy, but this effect was moderated by depression status. Consistent with Watkins' (2008) hypothesis, increases in sad mood and decreases in happiness were associated with shifts towards the use of more concrete action identifications in never-depressed individuals, but not in depressed patients. These findings suggest that the putatively adaptive association between mood and level of identification is impaired in major depression.

In a replication and extension of Watkins, Teasdale, and Williams (2003), a scrambled sentences paradigm was used to test whether prompting contextual processing of negative cognitive primes would limit the activation of dysphoric mood. Participants were divided into two groups and, after a dysphoric mood induction procedure, were asked to unscramble sentences that either did or did not emphasise the contextual aspects of moods. Consistent with Watkins et al., participants' despondency decreased significantly more in the contextual group than in the neutral group. This effect could not be accounted for by variations in the way sentences were unscrambled.

Two experiments are reported in which nondysphoric participants, not prone to excessive levels of rumination in everyday life, were asked to retrieve autobiographical memories using the Williams and Broadbent ( 1986 ) procedure (AMT). In the first experiment, two variants of a self-related category fluency task were interleaved among sets of autobiographical memory cues. In one variant (blocked) a normal model of analytic rumination was induced by grouping prompts on a single superordinate theme together. In the other (intermixed) prompts from several different themes were grouped together. It was predicted that the blocked variant would reduce the number of specific memories recollected and increase the number of categoric memories relative to the intermixed variant. This prediction was confirmed and provides the first demonstration of a bidirectional causal influence of analytic rumination on the balance between specific and categoric retrievals. A second experiment showed no alteration in this balance when the same fluency manipulation involved animal-related categories rather than self-related ones. The results support a two component model of autobiographical retrieval being driven in part by the extent to which an analytic mode of processing is adopted in the short term and in part by the level of differentiation in self-related schematic models.

This paper describes the limited availability of resources for common mental disorders and the unmet need for treatment for both anxiety and depression. A specific focus is to consider whether a self-referral approach to Stress can be adapted to meet the unmet need for treatment of people with depression. Results indicate that the take-up for a self-referral Depression workshop is much lower than that for the Stress workshops, particularly between the enquiry and the Introductory Talk stage. Additionally, those who came to the Introductory Talks for the Depression workshops were very similar to psychology service referrals. Over 90% had previously been to see their GP, been diagnosed and referred on to the specialist mental health services. It was concluded that the self-referral mechanism was not successful in meeting the unmet needs of those with depression who had not been previously referred. Suggestions are made about improving take-up and engagement for this group.
