Marriages and psychological distress among adult offspring of divorce: a Norwegian study

The study compares the likelihood of getting married and of getting divorced among the adult offspring of divorced parents versus the adult offspring of parents who remain married (total N = 37,230). It also compares levels of psychological distress in the two groups (total N= 22,898). Data derive from The Nord‐Trøndelag Health Study (HUNT) and population registries from Norway. Individuals with divorced parents tended to delay marriage or not marry at all. However, among those who married, there were more divorces among the offspring of divorced parents than among offspring of parents who were still married. Offspring of divorce tended to marry other offspring of divorce. These marriages were at especially high risk of dissolution. Parental divorce was particularly influential as a risk factor during the first years of marriage. Both parental divorce and the individuals’ own divorce were risk factors for psychological distress.     

Co-occurrence of personality disorders with mood, anxiety, and substance use disorders in a young adult population

The purpose of this study was to determine the co-occurrence of DSM- III-R personality disorders (PDs) with mood, anxiety, and substance use disorders in a young adult population. The members of the Northern Finland 1966 Birth Cohort Project, living in the city of Oulu with an age of 31 years (N = 1,609) were invited to participate in a two-phase field study. The SCID I and II were used as diagnostic instruments. One hundred and seventy-seven out of 321 interviewed subjects met the criteria for mood, anxiety, or substance use disorders. Altogether 72 (41%) of the subjects with an Axis I disorder met the criteria for at least one PD. The weighted co-occurrence rate of any PD varied from 28% for mood disorders to 47% for anxiety disorders. PDs, especially those in Cluster C, are highly associated with Axis I psychiatric disorders in population.     

Temperament in adults--reliability, stability, and factor structure of the EAS Temperament Survey

We assessed the factor structure and psychometric properties of the Emotionality, Activity, and Sociability (EAS) Temperament Survey (Buss & Plomin, 1984) for adults using a longitudinal sample of adult women. The stability estimates of the EAS instrument were assessed over a period of 3 years. The results indicated an acceptable fit for the basic theoretical EAS model, implying that the scale is functioning satisfactory. However, the results also suggest that the measure could be improved. Across time, latent stability factors explained within-scale covariances. Both latent stability factors and time-specific factors accounted for cross-sectional covariances between subscales. Additional research is warranted to guide the further development of the EAS model.     

Externalizing psychopathology in adulthood: a dimensional-spectrum conceptualization and its implications for DSM-V

Mental disorders involving antisocial behavior and substance use are genetically linked and vary continuously. The authors present a review and integrative conceptualization of these observations in terms of a dimensional and hierarchically organized externalizing spectrum. As a foundation for this conceptualization, the authors introduce a quantitative, model-based approach to comparing categorical and continuous conceptions of psychopathology and apply this approach in an empirical study of patterns of comorbidity among externalizing disorders as defined in the Diagnostic and Statistical Manual of Mental Disorders. The authors present evidence that comorbidity among externalizing disorders is best modeled by an underlying normally distributed continuum of risk for multiple disorders within the externalizing spectrum. The authors conclude by discussing implications of the externalizing spectrum conceptualization for classification of disorders in the upcoming 5th edition of the Diagnostic and Statistical Manual of Mental Disorders.     

Using latent trait modeling to conceptualize an alcohol problems continuum

Recent research points toward the viability of conceptualizing alcohol problems as arrayed along a continuum. Nevertheless, modern statistical techniques designed to scale multiple problems along a continuum (latent trait modeling; LTM) have rarely been applied to alcohol problems. This study applies LTM methods to data on 110 problems reported during in-person interviews of 1,348 middle-aged men (mean age=43) from the general population. The results revealed a continuum of severity linking the 110 problems, ranging from heavy and abusive drinking, through tolerance and withdrawal, to serious complications of alcoholism. These results indicate that alcohol problems can be arrayed along a dimension of severity and emphasize the relevance of LTM to informing the conceptualization and assessment of alcohol problems.     

Happiness and health: environmental and genetic contributions to the relationship between subjective well-being, perceived health, and somatic illness

The aim was to identify genetic and environmental influences on the covariances between subjective well-being (SWB), perceived health, and somatic illness. Analyses were based on 6576 Norwegian twins aged 18-31. Heritabilities ranged from .24 to.66. SWB correlated .50 with perceived health, -.25 with musculoskeletal pain, and -.07 with allergy. Common genetic factors accounted for 45%-60% of associations. SWB and perceived health was to a high extent influenced by the same genes (r(g)=.72 and.82 for males and females, respectively). For SWB and musculoskeletal pain, r-sub(g) =-.29 and -.42 for males and females, respectively. Effects were partly sex specific. Environmental factors shared by twins did not affect the covariances. Results support a differentiated view of SWB-health relations, and imply that both genes and environment play important roles in the associations between well-being and health.     

Zwischen der „Physik des Organischen” und der „Organisierung der Physik”: Überlegungen zu Gegenstand und Methode der Biologie

Between Physics of Organism and Organismic Physics: Object and Method of Biology. In the history of biological theory one can observe an oscillation between two tendencies of thinking, namely the biologistic and the physicalistic point of view. Both aim at a general or unified theory of nature that is relevant for scientific research as well as for philosophical reflection. In terms of a pluralistic approach these two ways of theory-formation must be rejected. Biology e.g. as a specific natural science, characterized by its mid-position between ‘nomothetic’ and ‘idiographic’ thinking (Windelband), is much more than a subordinate branch of physical knowledge. This very autonomy of biology does not only result from a special methodology or from a specific theoretical framework. On the contrary, the methodological and functional autonomy of biology is due to the very features of the phenomena investigated. These features include multitude, individuality and wholeness. This revised version was published online in August 2006 with corrections to the Cover Date.

Perceptual complexity,rather than valence or arousal accounts for distracter-induced overproductions of temporal durations

For humans and other species, the ability to estimate the physical passage of time is of fundamental importance for perceptual, cognitive or motor functions. Despite this importance, any subjective estimation of temporal durations not only depends on the temporal dynamics of the to-be-timed stimulus or event, but also can be distorted by non-temporal perceptual, cognitive, and emotional effects. This study aimed to further explore critical stimulus characteristics modulating distracter-induced distortions in human time-reproduction. To this end, we investigated whether subjectively rated distracter dimensions of arousal and valence (related to levels of emotionality), or rather stimulus complexity, as a confounder, produce distortions in participants' reproduction of a previously trained target interval. Accuracy and precision of time-reproduction have been measured in distracter-trials, and compared to timing performance in baseline-trials without any distraction. Results showed temporal overproductions in a magnitude of less than distracter duration only for complex distracters. Most importantly, arousal level and valence of distracters were not accountable for temporal distortions. Within an internal clock framework, our pattern of results can best be interpreted in the context of attention-, rather than arousal-based mechanisms of timing.
