Rumination, distraction, and mindful self-focus in depressed patients

Rumination has been proposed as a cognitive risk factor for the onset and maintenance of depression. In parallel, mindfulness interventions have shown to reduce the risk for recurrence of depressive episodes. This study aimed to investigate effects of short periods of induced rumination, distraction, and mindful self-focus on sad mood in depressed patients and to assess possible moderator effects of habitual variables on respective mood changes. Seventy-six depressed patients 3.5 years after discharge from inpatient treatment were subjected to negative mood induction and subsequently randomly assigned to a rumination, distraction, or mindful self-focus induction. Habitual aspects of rumination, distraction, and mindfulness were assessed by questionnaires. Compared to rumination, the induction of a mindful self-focus and of distraction showed clear beneficial effects on the course of negative mood. While habitual distraction predicted better mood outcomes across all conditions, patients high in habitual mindfulness tended to show stronger negative mood reduction specifically after the induction of a mindful self-focus. This study indicates that - similar to distraction - an experimentally induced mindful self-focus is able to reduce negative mood in depressed patients. Implications regarding possible subgroups of patients who might particularly benefit from mindfulness-based interventions are discussed.     

The development of an attentional bias for angry faces following Pavlovian fear conditioning

Although it is well documented that fear responses develop following aversive Pavlovian conditioning, it is unclear whether fear learning also manifests in the form of attentional biases for fear-related stimuli. Boschen, Parker, and Neumann (Boschen, M. J., Parker, I., & Neumann, D. L. (2007). Changes in implicit associations do not occur simultaneously to Pavlovian conditioning of physiological anxiety responses. Journal of Anxiety Disorders, 21, 788-803.) showed that despite the acquisition of differential skin conductance conditioned responses to angry faces paired (CS+) and unpaired (CS−) with an aversive shock, development of implicit associations was not subsequently observed on the Implicit Association Test. In the present study, participants (N = 76) were assigned either to a Shock or NoShock group and completed a similar aversive Pavlovian conditioning procedure with angry face CS+ and CS− stimuli. Participants next completed a visual probe task in which the angry face CS+ and CS− stimuli were paired with angry face control stimuli and neutral faces. Results confirmed that differential fear conditioning was observed in the Shock group but not in the NoShock group, and that the Shock group subsequently showed a selective attentional bias for the angry face CS+ compared with the CS− and control stimuli during the visual probe task. The findings confirm the interplay between learning-based mechanisms and cognitive processes, such as attentional biases, in models of fear acquisition and have implications for treatment of the anxiety disorders.     

Sensationalising sex offenders and sexual recidivism: Impact of the Serious Sex Offender Monitoring Act 2005 on media reportage

Differences in extent and nature of newspaper media reporting before and after the introduction of the Serious Sex Offender Monitoring Act 2005 in Victoria were investigated, critically exploring the interface between psychological, media and criminological disciplines. Forty‐three news items before the Act and 90 after the Act were analysed using a thematic and discursive framework. A significant increase in the number of items was found after the Act but other discursive and thematic findings were mixed. Several indicators of sensationalism such as headline size, tone, and theme did not differ between time frames, while there was a significant increase in the incidence of case‐based and high‐profile case reporting after the introduction of the Act. Hence, although the discourse and frames within which serious sex offenders are reported has remained similar over time, the introduction of the Act has dramatically impacted on the frequency of reporting in such cases. The findings are congruent with the extant literature on the newsworthiness of child sexual offending, indicating a need for media outlets to be more responsible in their reporting, and for legislators to enact legislation based upon empirical evidence.     

Öst's (2008) methodological comparison of clinical trials of acceptance and commitment therapy versus cognitive behavior therapy: Matching Apples with Oranges?

Öst (2008) recently compared the methodological rigor of studies of acceptance and commitment therapy (ACT) and traditional cognitive behavior therapy (CBT). He concluded that the ACT studies had more methodological deficiencies, and thus the treatment did not qualify as an “empirically supported treatment.” Although Öst noted several important limitations that should be carefully considered when evaluating early ACT research, his attempt to devise an empirical matching strategy by creating a comparison sample of CBT studies to bolster his conclusions was itself problematic. The samples were clearly mismatched in terms of the populations being treated, leading to differences in study design and methodology. Furthermore, reanalysis showed clear differences in grant support favoring CBT compared with ACT studies that were not reported in the original article. Given the actual mismatch between the samples, Öst's methodological ratings are difficult to interpret and provide little useful information beyond what could already be gathered by a qualitative review of ACT study limitations. Such limitations are characteristic of the earlier randomized controlled trials of any emerging psychotherapeutic approach.     

Failure to loose fear: The impact of cognitive load and trait anxiety on extinction

Exposure therapy is an effective technique for fear reduction. However, whether effective exposure requires attentional allocation to the feared situation remains a debated clinical issue. In the present study, the impact of attention allocation in extinction was investigated in an experimental conditioning study. Through a between-subjects manipulation of cognitive load, we created a condition in which participants could allocate their attention to the feared stimulus during extinction (low load condition), and a condition in which attentional allocation was impaired (high load condition). The influence of cognitive load on extinction was examined by comparing electrodermal responses and verbal ratings for the conditioned stimuli in the two extinction load conditions. The results show less successful extinction in the high load condition than in the low load condition. However, this effect was found only in low anxious participants, and it was prominent only on the skin conductance responses. The present results suggest that extinction is not automatic but requires cognitive resources.     

Improving psychological adjustment following a first episode of psychosis: A randomised controlled trial of cognitive therapy to reduce post psychotic trauma symptoms

There are few evaluated psychological interventions or theoretical approaches which are specifically aimed at reducing problems related to adjustment and adaptation following a first episode of psychosis. The present study tests the efficacy of a form of CBT (Cognitive Recovery Intervention; CRI) in reducing trauma, depression and low self esteem following a first episode of psychosis, in a single-blind randomised controlled trial. A total of 66 patients who had recently experienced a first episode of psychosis were randomly assigned to CRI or treatment as usual (TAU) and followed up at 6 and 12 months. People receiving CRI tended to have lower levels of post-intervention trauma symptoms and demonstrated greater improvement than those receiving TAU alone. This was especially the case at 6 months for those with high pre-treatment levels of trauma. There was, however, no advantage for the CRI group with regards to reduced depression or improved self esteem. In conclusion, CRI appears to be an effective intervention to help young people adapt to the traumatic aspects of a first episode of psychosis although further evaluation in a larger study is warranted.     

Effect of dichotomous thinking on the association of depression with BMI and weight change among obese females

This study tested whether a dichotomous thinking style moderates the association of depression with body mass, and investigated the effect of dichotomous thinking and depression on weight loss during a cognitive behavioural therapy (CBT) intervention.Overweight and obese females (n = 76) participated in CBT for weight management for 12 weeks. Before treatment, dichotomous thinking moderated the association of depression with BMI, such that depression was positively associated with BMI among those with low dichotomous thinking, but was not associated among those with high dichotomous thinking. Weight loss was negatively associated with pre-treatment depression and frequency of treatment attendance, but not with dichotomous thinking. Females who regard their weight as unacceptably high and who think dichotomously may experience high levels of depression irrespective of their actual weight, while depression may be proportionate to the degree of obesity among those who do not think dichotomously. Depression, but not dichotomous thinking, is likely to interfere with the ability to adhere to short-term weight loss strategies.     

Utilizing Family Strengths and Resilience: Integrative Family and Systems Treatment with Children and Adolescents with Severe Emotional and Behavioral Problems

Community mental health agencies are consistently challenged to provide realistic and effective home-based family-centered treatment that meets local needs and can realistically fit within available budget and resource capabilities. Integrated Family and Systems Treatment (I-FAST) is developed based on existing evidence-based approaches for working with at-risk children, adolescents, and families and a strengths perspective. I-FAST identified 3 evidence-based, core treatment components and integrated them into a coherent treatment protocol; this is done in a way that builds on and is integrated with mental health agencies' existing expertise in home-based treatment. This is an intervention development study in which we conducted an initial feasibility trial of I-FAST for treating families with children at risk of out-of-home placement. The outcomes of the study provide initial empirical evidence that supports the effectiveness of I-FAST. Findings indicate that there were significant improvements in child behavior, significant increases in parental competency, and significant increases in the level of cohesion and adaptability in these families. All observed changes were significant from pre- to posttreatment with the families able to maintain these positive changes at 6-month follow-up. A more rigorous and robust research design, however, will be needed to establish definitive evidence of the effectiveness of I-FAST.     

A developmental examination of the conceptual structure of animal, artifact, and human social categories across two cultural contexts

Previous research indicates that the ontological status that adults attribute to categories varies systematically by domain. For example, adults view distinctions between different animal species as natural and objective, but view distinctions between different kinds of furniture as more conventionalized and subjective. The present work (N = 435; ages 5-18) examined the effects of domain, age, and cultural context on beliefs about the naturalness vs. conventionality of categories. Results demonstrate that young children, like adults, view animal categories as natural kinds, but artifact categories as more conventionalized. For human social categories (gender and race), beliefs about naturalness and conventionality were predicted by interactions between cultural context and age. Implications for the origins of social categories and theories of conceptual development will be discussed.     

Concept-procedure interactions in children's addition and subtraction

A 3-week problem-solving practice phase was used to investigate concept-procedure interactions in children’s addition and subtraction. A total of 72 7- and 8-year-olds completed a pretest and posttest in which their accuracy and procedures on randomly ordered problems were recorded along with their reports of using concept-based relations in problem solving and their conceptual explanations. The results revealed that conceptual sequencing of practice problems enhances children’s ability to extend their procedural learning to new unpracticed problems. They also showed that well-structured procedural practice leads to improvement in children’s ability to verbalize key concepts. Moreover, children’s conceptual advances were predicted by their initial procedural skills. These results support an iterative account of the development of basic concepts and key skills in children’s addition and subtraction.
