  • Trait Hostility is Associated with Systemic Inflammation in Married Couples: An Actor-Partner Analysis.

    Biological Psychology

    Trait anger and hostility predict the development of coronary heart disease, and systemic inflammation may partly mediate this association. In a sample of 94 middle-aged and older married couples, we replicate research showing a within individuals (i.e., actor effect) association of trait hostility with high sensitivity C-reactive protein (hsCRP). As a novel extension of that research, the present study also examined the association of individuals' trait hostility with their partners' hsCRP (i.e., partner effect). Controlling for potential confounds, trait hostility, measured with the Buss-Perry Aggression Questionnaire, was significantly associated with both participants' own hsCRP, b=.0528 (SE=.0196), p=.008 and their partners' levels b=.0473 (SE=.0194), p=.016. Hence, the inflammatory correlates of trait hostility occur not only within individuals but between them, as well. The effects of unhealthy personality traits may extend to intimate partners and possibly other social network members.

  • A Cross-Sectional Analysis of the Association Between Perceived Network Social Control and Telomere Length

    Health Psychology

    Social control in the health domain refers to attempts by social network members to get an individual to modify their health behaviors. According to the dual effects model of social control, having one's health behavior controlled by others should be related to healthier behavioral change, but might arouse psychological distress as one may resent being controlled. Despite potential healthy behavior change, the stress of social control may thus be detrimental as interpersonal stress has been related to negative health outcomes. In the present study, the association between perceived social control and telomere length was tested to examine its association to biological outcomes.

  • Dispositional optimism and sleep quality: a test of mediating pathways.

    Journal of Behavioral Medicine

    Dispositional optimism has been related to beneficial influences on physical health outcomes. However, its links to global sleep quality and the psychological mediators responsible for such associations are less studied. This study thus examined if trait optimism predicted global sleep quality, and if measures of subjective well-being were statistical mediators of such links. A community sample of 175 participants (93 men, 82 women) completed measures of trait optimism, depression, and life satisfaction. Global sleep quality was assessed using the Pittsburgh Sleep Quality Index. Results indicated that trait optimism was a strong predictor of better PSQI global sleep quality. Moreover, this association was mediated by depression and life satisfaction in both single and multiple mediator models. These results highlight the importance of optimism for the restorative process of sleep, as well as the utility of multiple mediator models in testing distinct psychological pathways.

  • Loving-Kindness Meditation Improves Relationship Negativity and Psychological Well-Being: A Pilot Study

    Psychology

    Most interventions on relationships and health have focused on altering positive aspects of relationship such as social support. Given the separability of positive and negative aspects of relationships it is less clear if such interventions can also influence relationship negativity. This pilot study of 9 individuals tested the influence of a novel 6-week loving-kindness meditation (LKM) intervention on changes over time in social support, social negativity, depression, and life satisfaction. Consistent with past work, LKM participants showed increases in perceived support and decreases in depression. Extending prior work, LKM participants also showed decreases in social negativity, which was more closely linked to changes in depression compared to social support. These data suggest the feasibility of using LKM to increase relationship positivity, decrease relationship negativity, and enhance psychological well-being.

  • 100 million strong: A case study of group identification and deindividuation on Imgur.com

    New Media & Society

    Online groups can become communities, developing group identification and fostering deindividuation. But is this possible for very large, anonymous groups with low barriers to entry, highly constrained formats, and great diversity of content? Applying social identity theory and social identification and deindividuation effects theory, this study assesses influences on group identification and deindividuation in the case of Imgur.com. Respondents reported slightly positive levels of the three forms of group identification, but mixed levels of two forms of deindividuation. As argued by proponents of computer-mediated communication, demographics play only a minor role on these outcomes. More involved usage, such as direct access and commenting on images, is more associated with these outcomes, while more basic usage, such as total hours and reading comments, has little influence. Deindividuation is positively associated with group identification.

  • Social Relationships and Sleep Quality

    Annals of Behavioral Medicine

    Abstract BACKGROUND: The quality of social relationships and social support appears to be associated with physical health outcomes and sleep quality. Almost all previous research in this area focuses on positive aspects of relationships. PURPOSE: The present study thus intended to examine the links between supportive, aversive, ambivalent, and indifferent network ties and sleep quality. METHODS: Relationship data, Pittsburgh Sleep Quality Index (PSQI)-assessed sleep quality, and depression were examined in 175 middle-aged and older adults. RESULTS: Consistent with hypotheses, supportive ties were positively related to sleep quality, while aversive ties predicted worse sleep quality, associations that were primarily seen for close relationships. Ambivalent and indifferent ties were not significant predictors of sleep quality. Importantly, depression was found to mediate the link between relationship quality and sleep quality. CONCLUSIONS: These data suggest the more specific types of social relationships that may be linked to poor sleep quality and that depression appears to underlie these associations.

  • Dispositional optimism and sleep quality: a test of mediating pathways.

    Journal of Behavioral Medicine

    Dispositional optimism has been related to beneficial influences on physical health outcomes. However, its links to global sleep quality and the psychological mediators responsible for such associations are less studied. This study thus examined if trait optimism predicted global sleep quality, and if measures of subjective well-being were statistical mediators of such links. A community sample of 175 participants (93 men, 82 women) completed measures of trait optimism, depression, and life satisfaction. Global sleep quality was assessed using the Pittsburgh Sleep Quality Index. Results indicated that trait optimism was a strong predictor of better PSQI global sleep quality. Moreover, this association was mediated by depression and life satisfaction in both single and multiple mediator models. These results highlight the importance of optimism for the restorative process of sleep, as well as the utility of multiple mediator models in testing distinct psychological pathways.

  • Loving-Kindness Meditation Improves Relationship Negativity and Psychological Well-Being: A Pilot Study

    Psychology

    Most interventions on relationships and health have focused on altering positive aspects of relationship such as social support. Given the separability of positive and negative aspects of relationships it is less clear if such interventions can also influence relationship negativity. This pilot study of 9 individuals tested the influence of a novel 6-week loving-kindness meditation (LKM) intervention on changes over time in social support, social negativity, depression, and life satisfaction. Consistent with past work, LKM participants showed increases in perceived support and decreases in depression. Extending prior work, LKM participants also showed decreases in social negativity, which was more closely linked to changes in depression compared to social support. These data suggest the feasibility of using LKM to increase relationship positivity, decrease relationship negativity, and enhance psychological well-being.

  • 100 million strong: A case study of group identification and deindividuation on Imgur.com

    New Media & Society

    Online groups can become communities, developing group identification and fostering deindividuation. But is this possible for very large, anonymous groups with low barriers to entry, highly constrained formats, and great diversity of content? Applying social identity theory and social identification and deindividuation effects theory, this study assesses influences on group identification and deindividuation in the case of Imgur.com. Respondents reported slightly positive levels of the three forms of group identification, but mixed levels of two forms of deindividuation. As argued by proponents of computer-mediated communication, demographics play only a minor role on these outcomes. More involved usage, such as direct access and commenting on images, is more associated with these outcomes, while more basic usage, such as total hours and reading comments, has little influence. Deindividuation is positively associated with group identification.

  • Social Relationships and Sleep Quality

    Annals of Behavioral Medicine

    Abstract BACKGROUND: The quality of social relationships and social support appears to be associated with physical health outcomes and sleep quality. Almost all previous research in this area focuses on positive aspects of relationships. PURPOSE: The present study thus intended to examine the links between supportive, aversive, ambivalent, and indifferent network ties and sleep quality. METHODS: Relationship data, Pittsburgh Sleep Quality Index (PSQI)-assessed sleep quality, and depression were examined in 175 middle-aged and older adults. RESULTS: Consistent with hypotheses, supportive ties were positively related to sleep quality, while aversive ties predicted worse sleep quality, associations that were primarily seen for close relationships. Ambivalent and indifferent ties were not significant predictors of sleep quality. Importantly, depression was found to mediate the link between relationship quality and sleep quality. CONCLUSIONS: These data suggest the more specific types of social relationships that may be linked to poor sleep quality and that depression appears to underlie these associations.
