Genetic and environmental contributions to the co-occurrence of depressive personality disorder and DSM-IV personality disorders

One of the main controversies with regard to depressive personality disorder (DPD) concerns the co-occurrence with the established DSM-IV personality disorders (PDs). The main aim of this study was to examine to what extent DPD and the DSM-IV PDs share genetic and environmental risk factors, using multivariate twin modeling. The DSM-IV Structured Interview for Personality was applied to 2,794 young adult twins. Paranoid PD from Cluster A, borderline PD from Cluster B, and all three PDs from Cluster C were independently and significantly associated with DPD in multiple regression analysis. The genetic correlations between DPD and the other PDs were strong (.53-.83), while the environmental correlations were moderate (.36-.40). Close to 50% of the total variance in DPD was disorder specific. However, only 5% was due to disorder-specific genetic factors, indicating that a substantial part of the genetic vulnerability to DPD also increases the vulnerability to other PDs.     

Relationship quality,divorce, and well-being: Findings from a three-year longitudinal study

Recent studies indicate that divorce sometimes is positive for subjective well-being, but we lack knowledge about the circumstances under which this is the case. Further, we lack knowledge about the possible different associations between divorce and life satisfaction (LS) vs. positive affect (PA). The current study is based on the Norwegian Mother and Child Cohort Study (MoBa). Change in LS and PA over a three-year period was examined in women who divorced and women who did not divorce (N > 37,000). Relationship quality and relationship status at follow-up were included in the models. The results indicated that divorce predicted higher LS and PA when initial relationship quality was poor. Furthermore, divorce predicted higher PA for women who, after divorce, reported being in a new romantic relationship. The associations between relationship quality and LS and PA were stronger among not-divorced than divorced women, indicating that relationship quality affects LS and PA.     

The possible benefits of difficulty: how stress can increase and decrease subjective well-being

This study explores the effects of stress, trauma, coping and growth orientation on subjective well-being. Based on cognitive stress theory, it was hypothesized that adversity may contribute to increased or decreased well-being, depending on the subsequent meaning these experiences are given. Survey data from Norwegian UN/NATO veterans (N= 142) showed that stress and well-being were negatively associated (r=-0.20, p < 0.05) at the level of zero-order correlations. However, a full structural equation model revealed that the effect of stress on well-being was mediated positively through a problem-focused coping process combined with a growth component. Stress was negatively mediated through an avoidant-focused coping process and a distress component. The effect from stress was fully mediated in the model. The hypothesis that stress can produce both increased and decreased subjective well-being was confirmed.     

Underlying correlation structures of parental stress, general health and anxiety

A partial least square regression (PLSR) was performed on the Swedish Parenthood Stress Questionnaire (SPSQ) sum score and subscales on incompetence, role restriction, social isolation, spouse relationship and health problems, using 42 items from the General Health Questionnaire (GHQ) and 20 items from the State Anxiety Inventory (STAI-X1). The dataset contained 227 fathers and 301 mothers of children aged 1.0-6.6 years from a population-based study on parental psychological distress in the general Norwegian population, and all items correlated positively with SPSQ. Subscales on spouse relationship, incompetence, social isolation and role restriction related to items on state anxiety and depression. The SPSQ subscale on health problems related to GHQ items on somatic symptoms and social dysfunction. The STAI-X1 item "not feeling rested" had a particularly important effect on parental stress. Underlying correlation structures between parental stress and items from STAI-X1 and GHQ were explored, but only the SPSQ sum score could be acceptably predicted. PLSR as a statistical methodology was found useful for health and psychometric data.     

The role of working memory capacity in autobiographical retrieval: Individual differences in strategic search

Remembering previous experiences from one's personal past is a principal component of psychological well-being, personality, sense of self, decision making, and planning for the future. In the current study the ability to search for autobiographical information in memory was examined by having college students recall their Facebook friends. Individual differences in working memory capacity manifested itself in the search of autobiographical memory by way of the total number of friends remembered, the number of clusters of friends, size of clusters, and the speed with which participants could output their friends' names. Although working memory capacity was related to the ability to search autobiographical memory, participants did not differ in the manner in which they approached the search and used contextual cues to help query their memories. These results corroborate recent theorising, which suggests that working memory is a necessary component of self-generating contextual cues to strategically search memory for autobiographical information.     

Researching crisis—Recognizing the unsettling experience of emotions

Based on ethnographic research from Sri Lanka on post-tsunami recovery and displacement due to war, this article examines how emotions may have impacted on the research process and how the research participants (researcher, affected people, and partners) construct knowledge in crisis situations. The author discloses her own emotions while researching crisis and also explores the emotions that prevail among research participants in collaborations. Emotions are understood as mental and cultural constructions which unfold in the interaction between individuals and the world. A key driver for the author has been her commitment to those who suffer, which explains her willingness to take risk. It is argued that researchers who make themselves vulnerable to emotions not only make research more engaging and intelligible, but also provoke reflections. In places of crisis, both fluidity and pervasiveness of disillusionment prevail. Building on emotionally sensed knowledge of the research participants in such places, additional insights may be gained and new methods of discovery may be developed. A prerequisite for such a research agenda is a high level of trust and honesty among participants during fieldwork and beyond.     

Can a Happy Relationship Predict a Happy Life? A Population-Based Study of Maternal Well-Being During the Life Transition of Pregnancy,Infancy, and Toddlerhood

The association between overall life satisfaction (LS) and relationship satisfaction (RS) was investigated longitudinally among mothers (N=67,355), using data from the Norwegian Mother and Child Cohort Study (MoBa), conducted by the Norwegian Institute of Public Health. Data were collected twice during pregnancy, and at 6 and 36 months postpartum. Satisfaction increased during pregnancy, with RS decreasing immediately following birth and LS showing an initial increase followed by a decrease postpartum. The results showed that LS and RS levels were quite stable over time (.46-.75), as was their cross-sectional associations (.42-.59). Structural equation modeling using a cross-lagged longitudinal model evidenced cross-concept cross-time effects for both LS and RS. The strengths of the cross-effects were asymmetrical and life-phase specific, with RS predicting change in LS more than LS predicted changes in RS during pregnancy and infancy. Having a satisfying romantic relationship is important for retaining and increasing future life satisfaction.     

Injustice for All or Just for Me? Social Value Orientation Predicts Responses to Own Versus Other's Procedures

In two experiments, the authors investigated how differences in social value orientation predict evaluations of procedures that were accorded to self and others. Proselfs versus prosocials were either granted or denied an opportunity to voice an opinion in a decision-making process and witnessed how someone else was either granted or denied such an opportunity. Consistent with the hypothesis, procedural evaluations of both proselfs and prosocials were influenced by own procedure when other was granted voice, but only proselfs were influenced by own procedure when other was denied voice. These findings were particularly attributable to prosocials' tendency to evaluate a situation where no-voice procedures are applied consistently between persons more positively than proselfs. It is concluded that proselfs are focused on procedural justice and injustice for self more than prosocials, whereas prosocials value equality in procedures more than proselfs-even when equality implies injustice for all.     

Negative affectivity,coping, immune status,and disease progression in hiv iwected individuals

Abstract

The primary goal of the study was to assess the relationship between personality dispositions, coping styles, immune markers, clinical status, and subjective somatic symptoms in a mixed sample of HIV positive individuals. Specifically, the prognostic value of psychological and immunological measures in HIV progression was emphasized. Subjects (n = 104) were recruited from a cohort of 422 HIV positive individuals enrolled in the Oslo HIV Cohort Study. The partkipants were given self-administered questionnaires assessing behavioral, psychological, and psychdal variables. Clinical assessment and immunological tests were performed at regular follow-up visits. Clinical status was assessed according to the Centers for Disurse Control criteria. The immune markers used were CD4 T cell counts, beta2-microglobulin concentration, sewn levels of HIV-1 p24 core protein, and levels of antibodies to core protein. In addition, subjective somatic symptoms were assessed.

The results showed that measure-s of negative affectivity (NA; e.g. anxiety, distress, tension) were consistently related to subjective somatic symptoms and passivedefensive coping style. However, no amistent association between NA measures and immune markers was found. Individuals who developed AIDS in the study period had significantly lower initial CD4 cell counts as well as lower scores on measures of active-pmblem related wping (e.g. Positive reappraisal, Seeking social support) and passivedefensive coping (i.e. Escape-Avoidance, Self-control).

The results suggest (1) that coping styles may merit a specific focus in future research of psychological factors and medical outcomes in HIV infection, and (2) because of associations of NA measures with symptom reports studies of the relationship between e.g. stress, depression and HIV outcome should consider these variables as confounders.     

Measuring Postural Sway in Sitting: A New Segmental Approach

Global measures of trunk sway are traditionally used even though the trunk comprises a multiple number of segments. The authors’ aim was to measure the seated sway of typically developing children using a multisegment approach. Twenty typically developing children divided into 2 groups, older and younger than 10 years old, participated in this study. The children sat unsupported for 30 s while their posture and sway were quantified using stereophotogrammetry. The tendency in both age groups was to sit with a backward tilted pelvis and a kyphotic trunk. The sitting position was most varied in the younger group. Marker sway amplitude and velocity in sitting were age dependent, with reduced sway amplitude and velocity with increased age for all segments. Anteroposterior intersegmental angular sway was not age dependent. The difference in marker sway in the anteroposterior direction for the younger group appeared to result from an equally stable trunk supported on a less stable pelvis. Mediolateral marker sway and intersegmental angular sway showed a clearer age dependency. Trunk postural control does not appear to differ between children older and younger than 10 years old, but sagittal plane pelvic stability can explain the increased sway reported in younger children.
