Correspondence analysis used complementary to loglinear analysis

Loglinear analysis and correspondence analysis provide us with two different methods for the decomposition of contingency tables. In this paper we will show that there are cases in which these two techniques can be used complementary to each other. More specifically, we will show that often correspondence analysis can be viewed as providing a decomposition of the difference between two matrices, each following a specific loglinear model. Therefore, in these cases the correspondence analysis solution can be interpreted in terms of the difference between these loglinear models. A generalization of correspondence analysis, recently proposed by Escofier, will also be discussed. With this decomposition, which includes classical correspondence analysis as a special case, it is possible to use correspondence analysis complementary to loglinear analysis in more instances than those described for classical correspondence analysis. In this context correspondence analysis is used for the decomposition of the residuals of specific restricted loglinear models.     

A randomized clinical trial on the effectiveness of a reintegration training program versus booster sessions after short-term inpatient psychotherapy

Although several studies show symptomatic improvements in patients with personality disorders after short-term inpatient psychotherapy, reintegration remains difficult. In this study the effectiveness of a specifically designed reintegration training program is investigated. One hundred twenty-eight patients were randomized to either a reintegration training program aimed at improving general functioning and work resumption, or booster sessions. Outcome measures used were symptom level, work status, absence from and impediments at work. The results showed that compliance in the booster session group was significantly better than in the reintegration training program. The percentage of persons with a paid job increased during the booster sessions from 64 to 87%, but not during the reintegration training (76%). There were no differences in the other outcome measures. We concluded that reintegration training was not more (cost)-effective than booster sessions. Our hypothesis is that continuity of care (same therapists and program) explains the favorable results of the booster sessions.     

Burnout predictors among prison officers: The moderating effect of temperamental endurance

The study investigates whether work stressors, coping styles, and work-related social support predict burnout among prison officers (N = 476). It was hypothesized that coping and social support would mediate the effects of work stressors on burnout and that these effects would be moderated by temperamental endurance. Results of structural equation modeling showed that emotion-oriented coping was positively related to emotional exhaustion, and negatively to personal accomplishment. Task-oriented coping was positively related to personal accomplishment. Social support from work was negatively related to emotional exhaustion. The effects of work stressors on burnout were mediated by work-related social support and by emotion-oriented coping. Additionally, some of these mediating effects were moderated by endurance. Work-related social support was negatively related to depersonalization only among participants with strong endurance. High level of work stressors predicted high emotion-oriented coping only among individuals with weak endurance.     

Beyond the Class Norm: Bullying Behavior of Popular Adolescents and its Relation to Peer Acceptance and Rejection

This study examined to what extent bullying behavior of popular adolescents is responsible for whether bullying is more or less likely to be accepted or rejected by peers (popularity-norm effect) rather than the behavior of all peers (class norm). Specifically, the mean level of bullying by the whole class (class norm) was split into behavior of popular adolescents (popularity-norm) and behavior of non-popular adolescents (non-popularity-norm), and examined in its interaction with individual bullying on peer acceptance and peer rejection. The data stem from a peer-nominations subsample of TRAILS, a large population-based sample of adolescent boys and girls (N = 3312). The findings of multilevel regression analyses demonstrated that the negative impact of individual bullying on peer acceptance and the positive impact on peer rejection were particularly weakened by bullying by popular adolescents. These results place the class-norm effects found in previous person-group dissimilarity studies in a different light, suggesting that particularly bullying by popular adolescents is related to the social status attached to bullying.

Children’s Coping with In Vivo Peer Rejection: An Experimental Investigation

We examined children’s behavioral coping in response to an in vivo peer rejection manipulation. Participants (N=186) ranging between 10 and 13 years of age, played a computer game based on the television show Survivor and were randomized to either peer rejection (i.e., being voted out of the game) or non-rejection control. During a five-min. post-feedback waiting period children’s use of several behavioral coping strategies was assessed. Rejection elicited a marked shift toward more negative affect, but higher levels of perceived social competence attenuated the negative mood shift. Children higher in depressive symptoms were more likely to engage in passive and avoidant coping behavior. Types of coping were largely unaffected by gender and perceived social competence. Implications are discussed.     

Negative cognitions and avoidance in emotional problems after bereavement: a prospective study

Cognitive behavioural conceptualisations of grief propose that negative cognitions and avoidance strategies play a key role in emotional problems after bereavement. In the current study, this assumption was examined. Ninety-seven individuals who had lost a relative less than 5 months ago completed questionnaires tapping background and loss-related variables, negative cognitions (about the self, life, the future, and one's own grief reactions), avoidance, and symptoms of complicated grief (CG) and depression. Of these mourners, 70 people (72%) completed symptom measures again 6 months later at T2 (7-10 months after the loss), and 60 (62%) completed symptoms measures still 9 months later at T3 (16-19 months after the loss). Among other things, results showed that all four cognitive variables and the avoidance variable were strongly associated with concurrent and prospective symptom levels, even when the influence of relevant background/loss-related variables was controlled. In addition, independent of initial symptom levels, most of the cognitive variables predicted later CG and depression. The avoidance variable only predicted additional variance in depression at T3 beyond T1 symptom levels. Findings indicate that negative cognitions are important in emotional problems after bereavement and that the role of avoidance in the development of these problems needs further scrutiny.     

On the selective relation of frontal cortical asymmetry and anger-out versus anger-control

The model of anterior asymmetry and emotion proposes an asymmetric representation of approach and withdrawal systems in the left and right anterior brain regions. Within this framework, 3 different concepts have been related to anterior asymmetry: affective valence, motivational direction, and behavioral activation. The aim of the present study was an empirical investigation into the relation between anterior cortical activity and questionnaire measures related to the 3 dimensions positive versus negative affect, approach versus withdrawal motivation, and behavioral activation versus inhibition. Subjects with relative greater left than right frontal cortical activity showed higher anger-out scores and lower anger-control scores. These results support the hypothesis that motivational direction is related to frontal asymmetry (approach-left and withdrawal-right). Furthermore, subjects with greater bilateral (left and right) frontal cortical activity showed higher behavioral activation scores. This finding might suggest that behavioral activation is related to approach and withdrawal motivation.     

Adaptive memory: Is the animacy effect on memory due to emotional arousal?

Animate entities are often better remembered than inanimate ones. The proximal mechanisms underlying this animacy effect on recall are unclear. In two experiments, we tested whether the animacy effect is due to emotional arousal. Experiment 1 revealed that translations of the animate words used in the pioneering study of Nairne et al. (Psychological science, 24, 2099–2105, 2013) were perceived as being more arousing than translations of the inanimate words, suggesting that animacy might have been confounded with arousal in previous studies. In Experiment 2, new word lists were created in which the animate and inanimate words were matched on arousal (amongst several other dimensions), and participants were required to reproduce the animate and inanimate words in a free recall task. There was a tendency towards better memory for arousing items, but robust animacy effects were obtained even though animate and inanimate words were matched on arousal. Thus, while arousal may contribute to the animacy effect when it is not carefully controlled for, it cannot explain the memory advantage of animate items.
