Risk and protective processes and mechanisms associated with depression in youth are discussed within a developmental–ecological framework. Risk factors at the individual (genetics, biology, affect, cognition, behaviour) and broader contextual levels (e.g., family, school, community) are proposed to interact, leading to the development of depression in youth. Transactions between these individual and contextual factors are suggested to be dynamic and reciprocal, and these transactions are expected to change over time and developmental course. The ‘best bet’ for the prevention of depression may be multicomponent and multilevel interventions that address the multiple risk and protective factors associated with depression. Preventive interventions need to focus on building protective factors within young people themselves, as well as creating health-promoting environments at home and at school. These interventions likely need to be long term and geared towards assisting youth across successive periods of development.

Elevated anxiety sensitivity and the tendency to catastrophically misinterpret ambiguous bodily sensations has been demonstrated in people who experience nonclinical levels of panic (Richards, Austin, & Alvarenga, 2001), and anxiety sensitivity has been shown to be associated with insecure attachment in adolescents and young adults (Weems, Berman, Silverman, & Saavedra, 2001). This study investigated the relationship between attachment style, anxiety sensitivity and catastrophic misinterpretation among 11 nonclinical panickers and 58 nonanxious controls aged 18 to 19 years. Participants completed the Brief Bodily Sensations Interpretation Questionnaire (BBSIQ), Anxiety Sensitivity Index (ASI) and an attachment questionnaire. The hypothesis that insecurely attached individuals would demonstrate greater catastrophic misinterpretation and higher anxiety sensitivity than securely attached individuals was not supported; however, nonclinical panickers gave more anxiety-related interpretations of ambiguous internal stimuli than nonanxious controls. Results do not support the notion that attachment style is related to anxiety sensitivity or catastrophic misinterpretation (regardless of panic experience). Results do, however, support the notion that anxiety-related misinterpretation of ambiguous somatic sensations precedes the onset of panic disorder.

Little research has been undertaken to examine the empirical basis of commonly applied methods of posttrauma intervention. We propose that Pennebaker's work on structured disclosure of trauma provides a suitable analogue to explore questions of interest. The present study asks whether avoidance coping is likely to interfere with abbreviated disclosure of traumatic experiences. Subjects were 118 college students randomly allocated to either a one-session or four-session written trauma-disclosure condition. At 2 months postdisclosure, subjects with high avoidance coping within the one-session condition exhibited significantly more trauma-specific and physical symptoms than all other subjects. Avoidance coping significantly predicted trauma-specific symptoms at 2 months. These findings suggest that single session traumatic disclosure may not be useful for individuals with an avoidance style of coping.

Few studies have examined the impact of parenting interventions for families in rural and isolated areas who have children with conduct problems, where access to professional services can be difficult. The present investigation compared the effects of three conditions, two levels of self-directed behavioral family intervention: an enhanced self-directed program that combined a self-help program using written materials and a weekly telephone consultation (ESD), a self-help program (SD) and a waitlist control group (WL). At postintervention the ESD group reported significantly lower levels of disruptive behaviour, and lower levels of dysfunctional parenting than the SD and WL controls, and higher levels of consumer satisfaction. At 6 months follow-up the main effects for the ESD group had been maintained. The SD group continued to evidence improvement from postintervention to follow-up such that 65% of children in the ESD condition and 57% of children in the SD condition showed clinical reliable change on measures of disruptive behaviour. Implications of findings and directions for future research are discussed.

Despite the popular belief that chocolate adversely affects young children's behaviour, there have been no direct investigations into the behavioural response to chocolate consumption. This study investigated the effect of chocolate ingestion on the behaviour of 26 preschool children. Dried fruit was consumed in a separate condition to control for nonspecific factors, such as excitement and novelty, associated with the effects of receiving positive substances. Children were observed while they listened to a short story, immediately before and 30 minutes after they ate chocolate or fruit. The children's behaviours were videotaped and scored by two blind raters who coded their behaviours according to six objective and two subjective measures. There were no significant behavioural changes due to consumption of either chocolate or fruit on subjective and objective ratings. These findings raise questions about the popular perception that chocolate promotes poor attention and increased activity in preschool children.
