Fibromyalgia (FM) is a chronic musculoskeletal disorder characterized by widespread pain, fatigue, and a variety of other comorbid physiological and psychological characteristics, including a deficit of positive affect. Recently, the focus of research on the pathophysiology of FM has considered the role of a number of genomic variants. In the current manuscript, case-control analyses did not support the hypothesis that FM patients would differ from other chronic pain groups in catechol-O-methyltransferase (COMT) and mu-opioid receptor (OPRM1) genotype. However, evidence is provided in support of the hypothesis that functional single nucleotide polymorphisms on the COMT and OPRM1 genes would be associated with risk and resilience, respectively, in a dual processing model of pain-related positive affective regulation in FM. Forty-six female patients with a physician-confirmed diagnosis of FM completed an electronic diary that included once-daily assessments of positive affect and soft tissue pain. Multilevel modeling yielded a significant gene X environment interaction, such that individuals with met/met genotype on COMT experienced a greater decline in positive affect as daily pain increased than did either val/met or val/val individuals. A gene X environment interaction for OPRM1 also emerged, indicating that individuals with at least one asp allele were more resilient to elevations in daily pain than those homozygous for the asn allele. In sum, the findings offer researchers ample reason to further investigate the contribution of the catecholamine and opioid systems, and their associated genomic variants, to the still poorly understood experience of FM.

Research has suggested that lonely people demonstrate distinct differences from nonlonely people in their behaviors, mood, and interpersonal experiences. Lonely people who are also enduring a chronic pain condition may be at an especially high risk for negative outcomes because of simultaneous issues such as stigma, mood disturbances, and pain-related disability. The current study examined chronic and transitory loneliness in a sample of 123 chronic pain patients. Participants completed daily diaries assessing the occurrence of positive and negative interpersonal events, appraisals of interpersonal events, pain, and mood. Multilevel modeling was used to examine effects of being a lonely person as well as having a lonely episode on daily life. Results indicated that both chronic and transitory loneliness were associated with more frequent negative and less frequent positive interpersonal events, higher levels of pain, more negative and less positive affect, and more stress and less enjoyment from social interactions. Loneliness did not affect reactivity to negative interpersonal events, but did influence responsivity to positive interpersonal events such that lonely people had greater boosts in enjoyment when experiencing more positive interpersonal events than usual. These findings suggest that both lonely people and individuals experiencing a lonely episode experience more negative consequences in their daily lives than nonlonely people. However, they can benefit from engaging in more frequent positive interpersonal events, which can help to inform future clinical interventions for lonely, chronic pain patients.

In rehabilitation settings, activity limitation can be a significant barrier to recovery. This study sought to examine the effects of state and trait level benefit finding, positive affect, and catastrophizing on activity limitation among individuals with a physician-confirmed diagnosis of either Osteoarthritis (OA), Fibromyalgia (FM), or a dual diagnosis of OA/FM. Participants (106 OA, 53 FM, and 101 OA/FM) who had no diagnosed autoimmune disorder, a pain rating above 20 on a 0-100 scale, and no involvement in litigation regarding their condition were recruited in the Phoenix metropolitan area for inclusion in the current study. After initial questionnaires were completed, participants were trained to complete daily diaries on a laptop computer and instructed to do so a half an hour before bed each night for 30 days. In each diary, participants rated their average daily pain, benefit finding, positive affect, catastrophizing, and activity limitation. A single item, "I thought about some of the good things that have come from living with my pain" was used to examine the broader construct of benefit finding. It was hypothesized that state and trait level benefit finding would have a direct relation with activity limitation and a partially mediated relationship, through positive affect. Multilevel modeling with SAS PROC MIXED revealed that benefit finding was not directly related to activity limitation. Increases in benefit finding were associated, however, with decreases in activity limitation through a significant mediated relationship with positive affect. Individuals who benefit find had a higher level of positive affect which was associated with decreased activity limitation. A suppression effect involving pain and benefit finding at the trait level was also found. Pain appeared to increase the predictive validity of the relation of benefit finding to activity limitation. These findings have important implications for rehabilitation psychologists and should embolden clinicians to encourage patients to increase positive affect by employing active approach-oriented coping strategies like benefit finding to reduce activity limitation.

Cognitive reappraisal, or redefining the meaning of a stressful circumstance, is useful in regulating emotional responses to acute stressors and may be mobilized to up- or down- regulate the stressors’ emotional salience. A conceptually-related but more targeted emotion regulation strategy to that offered by cognitive reappraisal, termed positive cognitive shift, was examined in the current study. Positive cognitive shift (“PCS”) is defined as a point of cognitive transformation during a chronic, stressful situation that alters the meaning and emotional salience of the situation for the individual. Key aspects of the PCS that differentiate it from the broader reappraisal construct are that it 1) is relevant to responses to chronic (versus acute) aversive events, 2) is deployed when there is a mismatch between coping and stressors, and 3) involves insight together with redefinition in meaning of the situation generating stress. The current study used qualitative and quantitative analyses to 1) examine whether PCS is an observable, reliable, and valid experience in response to a stressful event that occurred in the past year, and 2) test whether PCS moderates the relations between the number of past-year stressful life circumstances and subsequent emotional well-being and functional health. A community sample of 175 middle-aged individuals were interviewed regarded a past chronic stressor and completed questionnaires regarding number of past year stressors and health outcomes. Theory-based coding of interviews was conducted to derive reliable scores for PCS, and findings indicated that PCS was evident in 37.7 % of participant responses. Furthermore, PCS scores were related positively to openness, personal growth from one’s most difficult lifetime event, and affect intensity-calm, in line with predictions. Also in line with prediction, PCS moderated the relations between number of past-year life events and health outcomes, such that the deleterious relations between past year stressful events and cognitive functioning, wellbeing, positive affect, and negative affect were weaker among individuals higher versus lower in PCS. Of note, PCS moderation effects diminished as the number of stressful events increased.

Introduction: The current study aimed to explore the prevalence rates of binge-eating and weight compensatory behaviors across sexual minority undergraduate men and women. Methods: The sample included 3411 undergraduate men and women from a large public university. Participants completed a self-report online questionnaire regarding various personality, social networking, and health behaviors. Results: Analyses showed no difference in binge-eating for women, but statistically significant differences across sexual orientation groups for weight compensatory behaviors. Analyses for men showed statistically significant differences between sexual orientation groups for objective-binge eating and self-induced vomiting. There were no differences among men for other behaviors. Discussion: These findings demonstrate both statistically and clinically significant differences across sexual orientation groups indicating that gender as well as sexual orientation bear a correlation to the propensity to engage in certain disordered eating behaviors.

In this study, potential differences in the manifestation and rates of eating disorders and symptoms (body dissatisfaction, weight and shape concerns, food restriction, and compensatory behaviors) in college women across sexual orientations were examined. The sociocultural model of eating disorders was also examined for these women across sexual orientations. The participants were organized into three different sexual orientation groups for analysis: heterosexual (group 1), bisexual, pansexual, and polysexual (group 2), and lesbian, gay, queer, transsexual, asexual, and other (group 3). Using cross-sectional data, it was revealed that there were significant group differences when comparing the three sexual orientation groups on loss of control over eating, but no significant group differences on body dissatisfaction, thin ideal internalization, and weight-related eating pathology, and total eating disorder symptoms scores. The sociocultural model was not predictive of eating disorder symptoms among non-heterosexual groups. Longitudinal analyses revealed that the sociocultural model of eating disorders prospectively predicts eating disorder symptoms among heterosexual women, but not non-heterosexual women. Both cross-sectional and longitudinal analyses indicate that non-heterosexual women may be protected from societal pressure to subscribe to the thin ideal and its subsequent internalization. However, the comparison group of heterosexual women in our study may not have been completely representative of undergraduate women in terms of total eating disorder symptoms or eating pathology. Additionally, regardless of sexual orientation, our sample reported more total eating disorder symptoms and emotional eating than previous studies. These findings have both clinical and research implications. Future research is needed to determine what risk factors and treatment target variables are relevant for non-heterosexual women.

The relationship of attachment style to both the selection and efficacy of emotion management strategies in adult dyadic contexts is not well elucidated. In non-romantic contexts, the interplay between emotion management and individual attachment style may provide a better understanding of how affect can be mitigated in daily life. The present study investigated these interactions by studying 56 pairs of college age women who were close friends. Participants were asked to have a conversation about a current source of concern/distress to one partner, while seated in the laboratory. After the conversation, participants were asked to report their subjective experience of several emotions during the conversation, such as ‘sadness,’ ‘joy,’ and ‘fear.’ Participants were also asked to complete a questionnaire assessing adult attachment style, specifically attachment anxiety and avoidance. Behavior during the conversation was coded for co-rumination and co-cognitive reappraisal by the “listener.” Listener attachment insecurity showed a trending association with increased use of co-detached reappraisal, for both avoidance (p=0.14) and anxiety (p=0.14). Listener attachment insecurity also predicted lower use of co-rumination, for both anxiety (p=0.10) and avoidance (p=0.02). Speaker attachment insecurity moderated the relationship between co-detached reappraisal and speaker emotion. Greater co-detached reappraisal predicted higher reports of non-fear negative and positive emotions, but only for high-avoidance speakers. Greater co-detached reappraisal also predicted greater non-fear negative emotions among speakers high, but not low, on attachment anxiety. Greater listener use of co-positive reappraisal was associated with higher reports of speaker fear; this effect was not moderated by speaker attachment style. These findings are discussed in relation to theoretical conceptions of attachment style, and in terms of the impact of context on emotion.

Social Networking Sites (SNSs), such as Facebook and Twitter, have continued to gain popularity worldwide. Previous research has shown differences in online behaviors at the cultural level, namely between predominantly independent societies, such as the United States, and predominantly interdependent societies, such as China and Japan. In the current study I sought to test whether self-construal was correlated with different ways of using SNSs and whether there might be SES differences within the US that were analogous to previously observed cross-cultural differences in SNS use. Higher levels of interdependence were linked with using SNSs to keep in touch with family and friends, and providing social support to others. Interdependence was also correlated with Facebook addiction scale scores, using SNSs in inappropriate situations, and overall SNS use. Implications for assessing risk for Internet addiction, as well as understanding cultural variations in prevalence of Internet addiction are discussed.

The Information Measurement Theory proposes that Type A people are perceptive and Type A people are capable of quicker change/adaptation. This study evaluated how transparency with past and present environments predicts their ability to grow and change in their current environment. People responded to a survey based on statements about personal life, specifically their relationship to their parents and the effect their parents have on their personal life. If a participant answered a certain way on the survey, they were asked for a further interview to evaluate IMT beliefs and environment beliefs more closely and specifically. The answers were evaluated using correlations, linear regression and a t-test. The results implicated that transparency is indicative of growth in Type C personalities but not necessary for growth in Type A personalities. The results also implicated that non-profit organizations are beneficial to growth in society.

A prior experiment by Li and colleagues found that when participants rated same sex faces in physical attractiveness, their self-reports of religiosity were higher in comparison to those that rated opposite sex faces. Could this be due to participants feeling their sexuality was threatened or misunderstood? In the current experiment, we attempted to replicate these findings and extend them by using a pseudo personality test that presented false feedback to participants. This feedback explained that their personalities were similar to homosexual or heterosexual people. Four hundred and fifty participants from Amazon Mturk were randomized into these conditions. We also measured homophobia, moral values, and the believability of the experiment. Results displayed no replication of the original findings. Men were more homophobic than women, while displaying lower moral values and religiosity. Those that self-reported being more homophobic also reported being more religious and moral. In conditions of sexual threat (homosexual personality, same sex faces) and sexual comfort (heterosexual personality, opposite sex faces), self-reports of moral values increased. Participants that reported believing the feedback displayed higher religiosity in both sexual threat and sexual comfort conditions. For a more concrete understanding of the relationship between religiosity, mating goals, and threats to sexuality, more research needs to be performed.
