Computer-assisted dieting: Effects of a randomised controlled intervention

In this pilot study, the effects of two computer-assisted dieting (CAD) interventions on weight loss and blood chemistry were examined among overweight and obese adults. Participants (91 community members, average age 42.6 years) were randomly assigned to CAD-only (a single-session introduction and provision of a dieting software, n = 30), CAD plus an additional four-session self-management group training (CAD+G, n = 31) and a waitlist control group whose members were randomised into the two interventions at the 3-month follow-up (n = 30). A three (group)-by-two (time) repeated measures ANOVA revealed no significant group by time interaction during the initial 3-month period. However, the two intervention groups combined showed a significant, though moderate weight loss relative to the control group. Further, although a general improvement was found with regard to the lipid panel results during the first 3 months of the trial, the treatment by time interaction was not significant. A comparison of the developments in the two intervention groups during the 3- to 6-month follow-up time period revealed a tendency towards greater weight regain in the CAD-only condition. The evidence suggests that CAD supports initial weight loss; however, additional self-management training might be necessary to support maintenance.     

Prediction of end-of-life fears in COPD – hoping for the best but preparing for the worst

Objective: The diagnosis of a life-threatening illness can trigger end-of-life fears. Early studies show that end-of-life fears play an important role in chronic obstructive pulmonary disease (COPD). However, predictors of these fears have not yet been identified. This study investigated the relevance of socio-demographic variables, illness severity, psychological distress and disease-specific anxieties as predictors of end-of-life fears in COPD.

Design: A total of 131 COPD patients participated at two time points. Regression and mediation analyses, as well as cross-lagged panel analyses were conducted.

Main outcome measures: The participants completed questionnaires assessing end-of-life fears (Multidimensional Orientation toward Dying and Death Inventory), psychological distress (Hospital Anxiety and Depression Scale), and disease-specific anxieties (COPD Anxiety Questionnaire). Pulmonary function and a 6-min walk test served as measures of illness severity.

Results: Illness severity was not predictive of end-of-life fears. However, gender and psychological distress explained incremental variance. When disease-specific anxieties were included as additional predictors, psychological distress was no longer significant. Cross-lagged panel analyses mostly supported these results. Moreover, disease-specific anxieties mediated the association between psychological distress and end-of-life fears.

Conclusion: Administration and intensity of end-of-life care (especially concerning end-of-life fears) in COPD patients should be based not only on illness severity, but rather on psychological distress and disease-specific anxieties.     

Coping strategies and quality of life in women with advanced breast cancer and their family caregivers

Abstract

This study examines the effects of personal resources of both heart patients and their close social partners on patients' coping and quality of life. Generalized personal resources (self-efficacy beliefs, dispositional optimism, self-regulation competence) and outcomes were assessed by questionnaire 1–3 days before surgery (n = 122) and again six months later (n= 50). Outcome variables were coping styles, social resources (social support and social integration), emotional states, and further measures of quality of life. Patients' personal resources were dominant in the prediction of most of the outcomes. Partners' resources were uniquely related to social support, social integration, and quality of life as perceived by the patients. Further, partners' personality resources predicted changes in patients' loneliness and energy levels during the six-month interval.     

Lobbying for Civil and Religious Rights of Immigrants and Muslims: Desecuritization Strategies of Islamic Umbrella Organizations in Germany

This article discusses how Islamic umbrella organizations advocate for civil rights of immigrants and Muslims in Germany. By focusing on the changing migration and security regimes at the turn of the twenty-first century, it analyzes the political emphasis on perceived “threats” in light of theoretical debates about the “securitization of migration”, and in particular, the role of Islamic organizations as lobbyists which publicly protest against associations being made between the two policy fields. Their public protest is against provisions of the new Nationality Act (2000) and the Immigration Act (2005) that require immigrants to prove German language skills, to be able to support themselves, and to pass naturalization tests as well as against the lack of dual citizenship and local voting rights. In addressing these issues, Islamic umbrella organizations expand their traditional scope of advocacy work to achieve religious rights for Muslim individuals and organizations, such as the official recognition of Islamic umbrella organizations and the introduction of Islamic religious education in public schools.     

Attentional Performance in Children and Adolescents with Tic Disorder and Co-Occurring Attention-Deficit/Hyperactivity Disorder: New Insights from a 2 × 2 Factorial Design Study

The aim of the present study was to investigate the effect of both tic disorder (TD) and attention-deficit/hyperactivity disorder (ADHD) on attentional functions. N = 96 children and adolescents participated in the study, including n = 21 subjects with TD, n = 23 subjects with ADHD, n = 25 subjects with TD+ADHD, and n = 27 controls. Attentional performance was tested based on four computerized attention tasks (sustained attention, divided attention, go/nogo and set shifting). The effect of TD as well as ADHD on attentional performance was tested using a 2 × 2 factorial approach. A diagnosis of TD had no negative impact on attentional functions but was associated with improved performance in the set shifting task. By contrast, regardless of a diagnosis of TD, subjects with ADHD were found to perform worse in the sustained attention, divided attention and go/nogo task. No interaction effect between the factors TD and ADHD was revealed for any of the attention measures. Our results add to findings from other areas of research, showing that in subjects with TD and ADHD, ADHD psychopathology is often the main source of impairment, whereas a diagnosis of TD has little or no impact on neuropsychological performance in most cases and even seems to be associated with adaptive mechanisms.     

Gains and losses in action memory.

Enacting action phrases (SPT for subject-performed task) produces better free recall than only learning the phrases verbally (VT for verbal task). A widespread explanation of the enactment effect is based on the distinction between item-specific and relational information. There is widespread agreement that the main reason is the excellent item-specific encoding by enactment. However, there is little direct evidence in the case of free recall. The role of relational information is less clear. We suggest that content-based relational encoding is better in VTs than in SPTs. In three experiments, in which multiple free recall testing used item gains and losses as indices of item-specific and content-based relational encoding, respectively, these assumptions were confirmed. Consistently more gains (indexing better item-specific encoding) and more losses (indexing poorer relational encoding) were observed in SPTs than in VTs (Experiments 1 and 2). Furthermore, it was demonstrated that the content-based relational information underlying losses is not identical with order-relational information (Experiment 2). In Experiment 3, it was shown that an item-specific orienting task for VTs produced an equivalent number of item gains and losses as did the SPT condition.     

Early tracking of informant accuracy and inaccuracy

Three‐ and four‐year‐old children (N=131) were tested for their sensitivity to the accuracy and inaccuracy of informants. Children were presented with one of three conditions. In the Accurate‐Inaccurate condition, one informant named objects accurately whereas the other named them inaccurately. In the Accurate‐Neutral condition, one informant named objects accurately whereas the other merely drew attention to them. Finally in the Inaccurate‐Neutral condition, one informant named objects inaccurately whereas the other merely drew attention to them. In subsequent test trials, 4‐year‐olds preferred to seek and accept information in a selective fashion across all three conditions, suggesting that they monitor informants for both accuracy and inaccuracy. By contrast, 3‐year‐olds were selective in the Accurate‐Inaccurate and Inaccurate‐Neutral conditions but not in the Accurate‐Neutral condition, suggesting that they monitor informants only for inaccuracy and take accuracy for granted.     

Influence of social support on adaptation to surgery.

The authors investigated the influence of patients' social support on subjective and objective stress indicators before, during, and after surgery. The sample consisted of 42 male and 42 female patients. Social support as perceived by the patients was measured by a surgery-specific inventory with the Emotional Support and Informational Support subscales. Perioperative adaptation was assessed by self-reported anxiety, the amount of narcotics needed for anesthesia induction, and the length of the postoperative stay. Results demonstrated that patients who scored high on social support showed less anxiety, received lower doses of narcotics, and had a shorter hospital stay than did patients with low support. However, gender was a moderator of some of these associations. Compared with men, women exhibited more relationships that were in accordance with the hypotheses.
