Treating chronic tinnitus: comparison of cognitive-behavioural and habituation-based treatments

Using a randomized control group trial the long-term efficacy of a habituation-based treatment as conceived by Jastreboff, and a cognitive-behavioural tinnitus coping training were compared. An educational intervention was administered as a control condition. Both treatments were conducted in a group format (habituation-based treatment, 5 sessions; tinnitus coping training, 11 sessions). Educational intervention was delivered in a single group session. Patients were categorized according to their level of disability due to tinnitus (low, high), age and gender and then randomly allocated to the treatment conditions (habituation-based treatment, n = 30; tinnitus coping training, n = 27; educational intervention, n = 20). Data assessment included follow-ups of up to 21 months. Several outcome variables including disability due to tinnitus were assessed either by questionnaire or diary. Findings reveal highly significant improvements in both tinnitus coping training and habituation-based treatment in comparison with the control group. While tinnitus coping training and habituation-based treatment do not differ significantly in reduction of tinnitus disability, improvement in general well-being and adaptive behaviour is greater in tinnitus coping training than habituation-based treatment. The decrease in disability remains stable throughout the last follow-up in both treatment conditions.     

Physiological and behavioral parameters of infants' categorization: changes in heart rate and duration of examining across trials

This report investigates the relations between duration of examining and heart rate (HR) across several trials of an object-examination task. A total of N= 20 11-month-olds were familiarized with a sequence of 10 different exemplars from the same global category (animals or furniture) before they received an exemplar from the contrasting category at test. Consistent with previous findings, HR was lower during states of focused attention (i.e. examining) than during states of casual attention (i.e. looking) or non-looking. Over the familiarization trials, examining stayed about the same, while mean HR increased. At test, examining increased and mean HR decreased, indicating that infants focused their attention on the out-of-category object. Psychophysiological and behavioral measures of attention were systematically related over trials, suggesting that heart rate provides a suitable objective measure to study infants' categorization performance in object-examination tasks.     

Affect regulation and food intake in bulimia nervosa: emotional responding to food cues after deprivation and subsequent eating

Emotional responding to salient food cues and effects of food deprivation and consumption were investigated in 32 women with bulimia and 32 control women. One half of each group was food deprived before viewing unpleasant, neutral, pleasant, and food-related pictures. Then participants could eat from a buffet before viewing a parallel picture set. Women with bulimia showed a substantial potentiation of startle responses during viewing of food cues relative to control women. This startle potentiation was attenuated by food deprivation and augmented by increased food consumption. These data support the affective regulation model suggesting that food cues prompt negative affective states in women with bulimia, who are overwhelmed by fasting. The resulting deprivation increases the incentive value of food cues and may thus trigger binge eating.

Precueing imminent conflict does not override sequence-dependent interference adaptation

Interference effects are largely reduced after cognitive conflicts in previous trials. This sequence-dependent interference adaptation is often seen as a consequence of strategic executive control. We sought to investigate whether sequential modulations are comparable with cue-induced strategic adjustments in spatial interference tasks. If so, reliable cues indicating the next compatibility condition should override effects caused by prior events. To this end, cues were introduced in a spatial stimulus-response compatibility task and a Simon task that either indicated the upcoming trial compatibility (rule cues) or the target position, which was not related to the S-R rule (position cues). The proportion of valid cues was either completely or predominantly valid. In both tasks cueing benefits for absolutely reliable rule cues were clearly present. Remarkably, sequential modulations were not influenced by effective rule cueing and vice versa. Even absolutely reliable information about prospective control demands did not cancel out sequence-dependent interference adaptation. In addition, the contingent negative variation—an event-related brain potential in the cue-target interval that is related to response preparation and readiness—showed additive effects of preceding compatibility and cue reliability. The present results indicate that processes underlying sequence-dependent interference adaptation differ from cue-induced strategic processes of cognitive control.     

A disgust mood state causes a negative interpretation bias, but not in the specific domain of body-related concerns

The present study was designed to examine the effects of a disgust mood state on negative interpretation bias, in particular in the domain of body and weight concerns. Participants (N = 120) were randomly assigned to one of four mood induction groups (i.e., disgust, anxiety, happy, and neutral) and were afterwards asked to respond to various types of ambiguous scenarios to index general threat interpretations, negative body-related interpretations, and neutral/positive interpretations. Results demonstrated that both the anxiety and disgust mood induction groups displayed higher levels of negative interpretations of the ambiguous threat scenarios than the neutral and happy groups. However, no evidence was obtained for a negative interpretation bias in the body-related domain for these negative mood groups, and this conclusion was also true for participants scoring high on a scale of eating disorder symptoms. Altogether, these findings suggest that disgust does not play a role in eating pathology by inducing a negative interpretation bias in the specific domain of body and weight concerns.     

Executive function and weight status in children: A one-year longitudinal perspective

There is considerable evidence for an association between obesity and impaired executive function (EF) in adolescents and adults. However, little research has examined EF in overweight or obese children. Furthermore, data on EF in underweight individuals is lacking. In addition, there is no consensus on the directionality of the relationship between Body Mass Index (BMI) and EF, and longitudinal studies are rare. Thus, the present study examined whether children differ in their performance on a battery of EF tasks depending on their weight status (underweight, normal-weight, overweight), and investigated the longitudinal cross-lagged associations between EF and BMI. Hot EF (delay of gratification, affective decision-making), cool EF (attention shifting, inhibition, working memory [WM] updating), and BMI were assessed in 1,657 German elementary-school children at two time points, approximately one year apart. Overweight children exhibited slightly poorer attention shifting, WM updating, and affective decision-making abilities as compared to normal-weight children. Unexpectedly, they did not show any deficits in inhibition or delay of gratification. EF levels of underweight children did not differ significantly from those of normal-weight children. Furthermore, poor attention shifting and enhanced affective decision-making predicted a slightly higher BMI one year later, and a higher BMI also predicted poorer attention shifting and WM updating one year later. The latter association between BMI and subsequent EF scores, however, diminished when controlling for socioeconomic status. Results indicate that hot and cool EF plays a role in the weight development of children, and might be a promising factor to address in preventive interventions.     

Erfassung der sozialen Ungleichheit in empirischen Untersuchungen

Background

The interrelationship between social inequality and health problems is well known. This paper evaluates how current empirical studies in the context of social psychiatry, psychosomatics and medical sociology respond to this issue in terms of taking characteristics of socio-economic status (SES) into account.

Material and methods

All empirical studies published in the German journals Psychotherapie, Psychosomatik und Medizinische Psychologie and Psychiatrische Praxis in 2005 and 2006 were evaluated regarding the use of characteristics of SES.

Results

Of the 113 studies examined, 70 (62%) covered characteristics of the SES. The majority included characteristics of both formal and professional education, but often in only few categories. Some studies used a combination of formal and professional education. Half of the studies included categories of occupational status or gainful employment, also often in few categories and 11% of studies included net family income. Three studies formed an index of social class using the categories lower class, middle class and upper class.

Conclusion

Determination of characteristics of SES can be improved both quantitatively and qualitatively. Comparability of population studies can be improved by an increased orientation on demographic standards.
