Effects of daily events on mood states in major depressive disorder

Major depressive disorder (MDD) is characterized by high negative affect (NA) and low positive affect (PA), but little is known about emotional reactivity in daily life. The authors used experience sampling methodology to investigate changes in NA and PA following minor daily events in MDD compared with healthy participants. Contrary to expectation, MDD participants did not report more frequent negative events, although they did report fewer positive events. Multilevel regression showed that both NA and PA responses to negative events were blunted in the MDD group, whereas responses to positive events were enhanced. NA responses to negative events persisted longer in MDD participants. Depressed participants with a positive family history or longer current episodes showed relatively greater NA responses to negative events.     

Developmental dyslexia in different languages: language-specific or universal?

Most of the research on developmental dyslexia comes from English-speaking countries. However, there is accumulating evidence that learning to read English is harder than learning to read other European orthographies (Seymour, Aro, & Erskine, 2003). These findings therefore suggest the need to determine whether the main English findings concerning dyslexia can be generalized to other European orthographies, all of which have less irregular spelling-to-sound correspondences than English. To do this, we conducted a study with German- and English-speaking children (n=149) in which we investigated a number of theoretically important marker effects of the reading process. The results clearly show that the similarities between dyslexic readers using different orthographies are far bigger than their differences. That is, dyslexics in both countries exhibit a reading speed deficit, a nonword reading deficit that is greater than their word reading deficit, and an extremely slow and serial phonological decoding mechanism. These problems were of similar size across orthographies and persisted even with respect to younger readers that were at the same reading level. Both groups showed that they could process larger orthographic units. However, the use of this information to supplement grapheme-phoneme decoding was not fully efficient for the English dyslexics.     

Signing enhances memory like performing actions

In three experiments, we investigated the influence of the overt performance of signs on memory. Deaf and hearing participants studied lists of action phrases (Experiment 1) or nouns (Experiment 2) under standard verbal instruction, under the instructions to sign the verbal phrase, to symbolically perform the denoted action, or to carry out a prototypical action corresponding to each noun. Higher recall and recognition performances were observed when actions were performed than in the verbal encoding condition, and signing was as effective for memory as was enactment. Thus, overt signing can induce an enactment effect. In contrast, Experiment 3 demonstrated that performing an unrelated action did not. A unique but unrelated action was not memory efficient.     

A social relations variance partitioning of dyadic behavior

The authors investigate the relative importance of actor and interaction partner as determinants of dyadic behavior. Using the social relations model (D. A. Kenny, 1994a; D. A. Kenny & L. La Voie, 1984), the authors estimate the variance attributable to each determinant plus the reciprocity of behavioral responses from 7 studies. The authors find evidence for moderate behavioral consistency in a person's behavior across interaction partners, little or no evidence that people consistently engender the same behavioral response from others, and preliminary evidence of unique responding to particular partners. They also consider several methodological issues concerning behavioral measurement as well as the implications of the results for the study of accuracy.     

Daily interpersonal experiences, context, and alcohol consumption: crying in your beer and toasting good times

The authors explored a multidimensional view of drinking, whereby social and solitary drinking represent distinct behaviors associated with positive and negative experiences, respectively. Using daily diary methodology and multilevel analytic strategy, the authors examined, over 30 days, the within-person association of negative and positive experiences and alcohol consumption in different contexts and focused on interpersonal experiences. On days with more negative interpersonal experiences, participants engaged in more solitary drinking (i.e., drinking at home and alone), whereas on days with more positive interpersonal experiences they drank more in social contexts. The authors also demonstrated that individuals high on neuroticism drank more in solitary contexts on days with more negative interpersonal experiences, relative to those with lower neuroticism. These findings lend support to models linking daily drinking motivation and context-dependent drinking behavior.     

Validation of the URICA-S in Group Therapy: Associations of Stages of Change with Therapeutic Factors and Treatment Outcome

Stages of change could be driving forces to activate the realization of therapeutic factors and symptom change. Consequently, the aims of the present study were to investigate whether the stages of change concept is valid in group therapy settings shown by factor analysis, internal consistencies, and criterion validity. A total of 377 patients completed measures of stages of change, symptom change, and therapeutic factors. A confirmatory factor analysis replicated the stages of change factors for group therapy. Related to the criterion validity, stages of change demonstrated only low, non-significant associations with symptom change, but some stages of change were significant predictors of certain therapeutic factors. Further research is needed to explore whether a stronger focus on motivational stages of change could help to intensify the realization of therapeutic factors in group therapy.     

A comparison of cognitive restructuring and cognitive defusion as strategies for resisting a craved food

The present study investigated the effectiveness of two cognitive strategies for resisting a craved food. One-hundred-and-ten self-identified chocolate cravers were randomised to a waiting list control condition or to receive a 60-minute standardised group intervention on cognitive restructuring (CR) or cognitive defusion (CD). All participants were provided with a bag of chocolates which they were instructed to carry with them for seven days and try to resist eating; uneaten chocolates were returned at the end of the study period. Measures included chocolate consumption and other behavioural, cognitive and evaluative self-reported outcomes. Overall, the odds of abstinence from chocolate were 3.26 times higher for participants in the CD than the CR condition. The effect of the interventions depended on baseline cognitive distress levels; for individuals at high levels of cognitive distress the CD condition led to significantly more restraint from chocolate than both the CR and control conditions. In addition, CD led to greater self-reported improvements in eating behaviours during the study period and was rated significantly easier to use and apply than CR. CD is discussed as a simple and efficient approach to manage food cravings and, potentially, other behavioural contributors to obesity.     

Construct validity of the Anxiety Sensitivity Index-3 in clinical samples

Using two clinical samples of patients, the presented studies examined the construct validity of the recently revised Anxiety Sensitivity Index-3 (ASI-3). Confirmatory factor analyses established a clear three-factor structure that corresponds to the postulated subdivision of the construct into correlated somatic, social, and cognitive components. Participants with different primary clinical diagnoses differed from each other on the ASI-3 subscales in theoretically meaningful ways. Specifically, the ASI-3 successfully discriminated patients with anxiety disorders from patients with nonanxiety disorders. Moreover, patients with panic disorder or agoraphobia manifested more somatic concerns than patients with other anxiety disorders and patients with nonanxiety disorders. Finally, correlations of the ASI-3 scales with other measures of clinical symptoms and negative affect substantiated convergent and discriminant validity. Substantial positive correlations were found between the ASI-3 Somatic Concerns and body vigilance, between Social Concerns and fear of negative evaluation and socially inhibited behavior, and between Cognitive Concerns and depression symptoms, anxiety, fear of negative evaluation, and subjective complaints. Moreover, Social Concerns correlated negatively with dominant and intrusive behavior. Results are discussed with respect to the contribution of the ASI-3 to the assessment of anxiety-related disorders.     

Assessing the Level of Structural Integration Using Operationalized Psychodynamic Diagnosis (OPD): Implications for DSM-5

A key ingredient in the current proposal of the DSM-5 Work Group on Personality and Personality Disorders is the assessment of overall severity of impairment in personality functioning: the Levels of Personality Functioning Scale (LPFS). The aim of this article is to contribute a conceptual and empirical discussion of the LPFS from the perspective of the Operationalized Psychodynamic Diagnosis (OPD) system (OPD Task Force, 2008 ). First, we introduce the OPD Levels of Structural Integration Axis (OPD-LSIA), a measure of individual differences in severity of personality dysfunction that is rooted in psychodynamic theory. We show that the OPD-LSIA is reliable, valid, and highly associated with observer ratings of personality disorders. In the second part, we present results from an OPD expert consensus study exploring potential limitations of the current LPFS item set from the perspective of the OPD-LSIA. We conclude with highlighting implications for future revisions of the DSM-5 proposal.     

Effects of individual aerobic performance on finish time in mountain running

It was hypothesized that for each mountain running competition, there is a certain individual performance level below which running times increase dramatically. The running times of 869 finishers of 3 international mountain running competitions have been analysed. A hyperbolic association was demonstrated between finish times in mountain running competitions and individual performance at the anaerobic threshold (VO2AT(Race)). Due to the non-linear association, there is an increasing effect on both the finish time and the change of finish time with decreasing aerobic performance. In all three competitions, the change of finish time is about 7 times more pronounced in mountain runners with the lowest VO2ATL,, compared to those with the highest values of VO2AT(Race). Both athletes and organizers should keep in mind these effects of decreasing aerobic performance on running times and potentially associated risks.
