Description
Fibromyalgia (FM) is a chronic pain condition characterized by debilitating fatigue. This study examined the dynamic relation between interpersonal enjoyment and fatigue in 102 partnered and 74 unpartnered women with FM. Participants provided three daily ratings for 21 days. They rated their fatigue in late morning and at the end of the day. Both partnered and unpartnered participants reported their interpersonal enjoyment in the combined familial, friendship, and work domains (COMBINED domain) in the afternoon. Additionally, partnered participants reported their interpersonal enjoyment in the spousal domain. The study was guided by three hypotheses at the within-person level, based on daily diaries: (1) elevated late morning fatigue would predict diminished afternoon interpersonal enjoyment; (2) diminished interpersonal enjoyment would predict elevated end-of-day fatigue; (3) interpersonal enjoyment would mediate the late morning to end-of-day fatigue relationship. In cross-level models, the study explored whether individual differences (between-person) in late morning fatigue and afternoon interpersonal enjoyment would moderate within-person relations from late morning fatigue to afternoon interpersonal enjoyment, and from afternoon interpersonal enjoyment to end-of-day fatigue. Furthermore, it explored whether the hypothesized relationships at the within-person level would also emerge at the between-person level (between-person mediation models). Multilevel structural equation modeling and multilevel modeling were employed for model testing, separately for partnered and unpartnered participants. Within-person mediation models supported that on high fatigue mornings, afternoon interpersonal enjoyment was dampened in the spousal and combined domains in partnered and unpartnered samples. Moreover, low afternoon interpersonal enjoyment in both the spousal and combined domains predicted elevated end-of-day fatigue. Afternoon interpersonal enjoyment mediated the relationship of late morning to end-of-day fatigue in the combined domain but in not the spousal domain. Cross-level moderation analyses showed that individual differences in afternoon spousal enjoyment moderated the day-to-day relation between afternoon spousal enjoyment and end-of-day fatigue. Finally, the mediational chain was not observed at the between-person level. These findings suggest that preserving interpersonal enjoyment in non-spousal relations limits within-day increases in FM fatigue. They highlight the importance of examining domain-specificity in interpersonal enjoyment when studying fatigue, and suggest that targeting enjoyment in social relations may improve the efficacy of existing treatments.

Description
Accumulating evidence implicates exposure to adverse childhood experiences in the development of hypocortisolism in the long-term, and researchers are increasingly examining individual-level mechanisms that may underlie, exacerbate or attenuate this relation among at-risk populations. The current study takes a developmentally and theoretically informed approach to examining episodic childhood stressors, inherent and voluntary self-regulation, and physiological reactivity among a longitudinal sample of youth who experienced parental divorce. Participants were drawn from a larger randomized controlled trial of a preventive intervention for children of divorce between the ages of 9 and 12. The current sample included 159 young adults (mean age = 25.5 years; 53% male; 94% Caucasian) who participated in six waves of data collection, including a 15-year follow-up study. Participants reported on exposure to negative life events (four times over a 9-month period) during childhood, and mothers rated child temperament. Six years later, youth reported on the use of active and avoidant coping strategies, and 15 years later, they participated in a standardized psychosocial stress task and provided salivary cortisol samples prior to and following the task. Path analyses within a structural equation framework revealed that a multiple mediation model best fit the data. It was found that children with better mother-rated self-regulation (i.e. low impulsivity, low negative emotionality, and high attentional focus) exhibited lower total cortisol output 15 years later. In addition, greater self-regulation in childhood predicted greater use of active coping in adolescence, whereas a greater number of negative life events predicted increased use of avoidant coping in adolescence. Finally, a greater number of negative events in childhood predicted marginally lower total cortisol output, and higher levels of active coping in adolescence were associated with greater total cortisol output in young adulthood. Findings suggest that children of divorce who exhibit better self-regulation evidence lower cortisol output during a standardized psychosocial stress task relative to those who have higher impulsivity, lower attentional focus, and/or higher negative emotionality. The conceptual significance of the current findings, including the lack of evidence for hypothesized relations, methodological issues that arose, and issues in need of future research are discussed.

Description
Type 1 Diabetes Mellitus (T1DM) is a chronic disease that requires maintaining tight metabolic control through complex behavioral and pharmaceutical regimens. Subtle cognitive impairments and stress response dysregulation may partially account for problems negotiating life changes and maintaining treatment adherence among emerging adults. The current study examined whether young adults with T1DM physiologically respond to psychological stress in a dysregulated manner compared to non-diabetic peers, and if such individuals also demonstrated greater cognitive declines following psychological stress. Participants included 23 young adults with T1DM and 52 non-diabetic controls yoked to T1DM participants based on age, gender, ethnicity, participant education, and maternal education. Participants completed a laboratory-based social stressor, pre- and post-stressor neurocognitive testing, provided fingerstick blood spots (for glucose levels) and salivary samples (for cortisol levels) at five points across the protocol, and completed psychosocial questionnaires. Related measures ANOVAs were conducted to assess differences between T1DM participants and the average of yoked controls on cortisol and cognitive outcomes. Results demonstrated that differences in cortisol reactivity were dependent on T1DM participants' use of insulin pump therapy (IPT). T1DM participants not using IPT demonstrated elevated cortisol reactivity compared to matched controls. There was no difference in cortisol reactivity between the T1DM participants on IPT and matched controls. On the Stroop task, performance patterns did not differ between participants with T1DM not on IPT and matched controls. The performance of participants with T1DM on IPT slightly improved following the stressor and matched controls slightly worsened. On the Trail Making Test, the performance of participants with T1DM was not different following the stressor whereas participants without T1DM demonstrated a decline following the stressor. Participants with and without T1DM did not differ in patterns of performance on the Rey Verbal Learning Task, Sustained Attention Allocation Task, Controlled Oral Word Association Task, or overall cortisol output across participation. The results of this study are suggestive of an exaggerated cortisol response to psychological stress in T1DM and indicate potential direct and indirect protective influences of IPT.

Description
Although anxiety may be developmentally appropriate, it can become problematic in some youth. From an ecological perspective, social systems, like family and friendships, are theorized to influence developmental trajectories toward (mal)adjustment, but empirical evidence is scant with regard to the relative impact of subjective satisfaction with family and friendship on anxiety problem development. This thesis study used a subsample of approximately 50% Hispanic/Latino clinic-referred youth (n = 71, ages 6-16 years). Overall, results suggest that the effect of friendship satisfaction on anxiety varied as a function of age but not ethnicity, such that there was a significant negative relationship between child-reported friendship satisfaction and anxiety levels for older children (approx. 9 years and older) but not for younger children. The effect of family satisfaction on anxiety also varied as a function of age, such that older children showed a positive relation between child reported family satisfaction and parent reported anxiety. Furthermore, a positive relation between family satisfaction and anxiety was found only for the H/L children. Post hoc analyses regarding cultural underpinnings of this finding and implications for future research are discussed, as are the results regarding differences between parent and child reports of anxiety.

Description
The use of bias indicators in psychological measurement has been contentious, with some researchers questioning whether they actually suppress or moderate the ability of substantive psychological indictors to discriminate (McGrath, Mitchell, Kim, & Hough, 2010). Bias indicators on the MMPI-2-RF (F-r, Fs, FBS-r, K-r, and L-r) were tested for suppression or moderation of the ability of the RC1 and NUC scales to discriminate between Epileptic Seizures (ES) and Non-epileptic Seizures (NES, a conversion disorder that is often misdiagnosed as ES). RC1 and NUC had previously been found to be the best scales on the MMPI-2-RF to differentiate between ES and NES, with optimal cut scores occurring at a cut score of 65 for RC1 (classification rate of 68%) and 85 for NUC (classification rate of 64%; Locke et al., 2010). The MMPI-2-RF was completed by 429 inpatients on the Epilepsy Monitoring Unit (EMU) at the Scottsdale Mayo Clinic Hospital, all of whom had confirmed diagnoses of ES or NES. Moderated logistic regression was used to test for moderation and logistic regression was used to test for suppression. Classification rates of RC1 and NUC were calculated at different bias level indicators to evaluate clinical utility for diagnosticians. No moderation was found. Suppression was found for F-r, Fs, K-r, and L-r with RC1, and for all variables with NUC. For F-r and Fs, the optimal RC1 and NUC cut scores increased at higher levels of bias, but tended to decrease at higher levels of K-r, L-r, and FBS-r. K-r provided the greatest suppression for RC1, as well as the greatest increases in classification rates at optimal cut scores, given different levels of bias. It was concluded that, consistent with expectations, taking account of bias indicator suppression on the MMPI-2-RF can improve discrimination of ES and NES. At higher levels of negative impression management, higher cut scores on substantive scales are needed to attain optimal discrimination, whereas at higher levels of positive impression management and FBS-r, lower cut scores are needed. Using these new cut scores resulted in modest improvements in accuracy in discrimination. These findings are consistent with prior research in showing the efficacy of bias indicators, and extend the findings to a psycho-medical context.

Description
Although social learning and attachment theories suggest that parent-adolescent relationships influence adult romantic relationships, research on this topic is limited. Most research examining relations between mother-adolescent and father-adolescent relationship quality and young adult romantic relationship quality has found significant effects of mother-adolescent relationship quality. Findings on fathers have been less consistent. These relations have not been examined among youth who experienced parental divorce, which often negatively impacts parent-child relationships and romantic outcomes. Further, no prior studies examined interactive effects of mother-adolescent and father-adolescent relationship quality on romantic attachment. The current study used longitudinal data from the control group of a randomized controlled trial of a preventative intervention for divorced families to examine unique and interactive effects of mother-adolescent and father-adolescent relationship quality on young adult romantic attachment. The 72 participants completed measures of mother-adolescent relationship quality and father-adolescent relationship quality during adolescence (ages 15-19), and completed a measure of romantic attachment (anxiety and avoidance) during young adulthood (ages 24-28). Findings revealed significant interactive effects of mother-adolescent and father-adolescent relationship quality on young adult romantic anxiety. The pattern of results suggests that having a high quality relationship with one's father can protect children from negative effects of having a low quality relationship with one's mother on romantic anxiety. These results suggest the importance of examining effects of one parent-adolescent relationship on YA romantic attachment in the context of the other parent-adolescent relationship. Exploratory analyses of gender revealed that father-adolescent relationship quality significantly interacted with gender to predict romantic avoidance; this relation was stronger for males. These results suggest that nonresidential fathers play an important role in adolescents' working models of relationships and their subsequent romantic attachment.

Description
The present study examined the association of pain intensity and goal progress in a community sample of 132 adults with chronic pain who participated in a 21 day diary study. Multilevel modeling was employed to investigate the effect of morning pain intensity on evening goal progress as mediated by pain's interference with afternoon goal pursuit. Moderation effects of pain acceptance and pain catastrophizing on the associations between pain and interference with both work and lifestyle goal pursuit were also tested. The results showed that the relationship between morning pain and pain's interference with work goal pursuit in the afternoon was significantly moderated by a pain acceptance. In addition, it was found that the mediated effect differed across levels of pain acceptance; that is: (1) there was a significant mediation effect when pain acceptance was at its mean and one standard deviation below the mean; but (2) there was no mediation effect when pain acceptance was one standard deviation above the mean. It appears that high pain acceptance significantly attenuates the power of nociception in disrupting one's work goal pursuit. However, in the lifestyle goal model, none of the moderators were significant nor was there a significant association between pain interference with goal pursuit and goal progress. Only morning pain intensity significantly predicted afternoon interference with lifestyle goal pursuit. Further interpretation of the present findings and potential explanations of those inconsistencies are elaborated on discussion. Limitations and the clinical implication of the current study were considered, along with suggestions for future studies.

Description
The population of older adults and the percentage of people living in urban areas are both increasing in the U.S. Finding ways to enhance city-dwelling, older adults' social integration, cognitive vitality, and connectedness to nature were conceptualized as critical pathways to maximizing their subjective well-being (SWB) and overall health. Past research has found that gardening is associated with increased social contact and reduced risk of dementia, and that higher levels of social support, cognitive functioning, mindfulness, and connectedness to nature are positively related to various aspects of SWB. The present study was a pilot study to examine the feasibility of conducting a randomized, controlled trial of community gardening and to provide an initial assessment of a new intervention--"Mindful Community Gardening," or mindfulness training in the context of gardening. In addition, this study examined whether community gardening, with or without mindfulness training, enhanced SWB among older adults and increased social support, attention and mindfulness, and connectedness to nature. Fifty community-dwelling adults between the ages of 55 and 79 were randomly assigned to one of three groups: Traditional Community Gardening (TCG), Mindful Community Gardening (MCG), or Wait-List Control. The TCG and MCG arms each consisted of two groups of 7 to 10 participants meeting weekly for nine weeks. TCG involved typical gardening activities undertaken collaboratively. MCG involved the same, but with the addition of guided development of non-judgmental, present-focused awareness. There was a statistically significant increase in different aspects of mindfulness for the TCG and the MCG arms. The interventions did not measurably impact social support, attention, or connectedness to nature in this small, high functioning, pilot sample. Qualitative analysis of interview data from 12 participants in the TCG and MCG groups revealed that both groups helped some participants to better cope with adversity. It was concluded that it is feasible to conduct randomized, controlled trials of community gardening with urban older adults, and considerations for implementing such interventions are delineated.

Description
The beginning of college is a period in which increased alcohol use often coincides with greater involvement in romantic relationships. Existing literature yields inconsistent findings regarding the influence of different relationship statuses on drinking behavior, perhaps because these studies have not accounted for recent changes in the way college students engage in dating/sexual relationships. In the current college environment, many students who define themselves as non-daters are nonetheless sexually active, a phenomenon referred to as the 'hook up' culture. The present study sought to address this issue by examining the effects of both relationship status and sexual activity on heavy episodic drinking (HED) among 1,467 college students over the course of their first three semesters. Results indicated that the effects of relationship status depended on whether or not an individual was sexually active. Non-dating but sexually active students reported rates of heavy drinking comparable to students who defined themselves as casual daters, but non-dating students who were not sexually active reported drinking behavior similar to those involved in committed relationships. Further, transitions between low and high risk relationship/sexual activity statuses were associated with corresponding changes in HED. Transitioning into a high risk status was associated with greater levels of heavy episodic drinking, whereas transitioning into a low risk status was associated with decreases in this behavior. Together, results indicate that engaging in nonexclusive dating or sexual relationships may play an important role in the development of problematic patterns of alcohol use during the early college years. These findings have potentially important implications both for future research and for prevention and intervention efforts targeting high risk college drinkers.

Description
This study examined whether cognitive behavioral therapy and mindfulness interventions affect positive (PA) and negative affect (NA) reports for patients with rheumatoid arthritis (RA) before, during, and after stress induction. The study also investigated the effects of a history of recurrent depression on intervention effects and testing effects due to the Solomon-6 study design utilized. The 144 RA patients were assessed for a history of major depressive episodes by diagnostic interview and half of the participants completed a laboratory study before the intervention began. The RA patients were randomly assigned to 1 of 3 treatments: cognitive behavioral therapy for pain (P), mindfulness meditation and emotion regulation therapy (M), or education only attention control group (E). Upon completion of the intervention, 128 of the RA patients participated in a laboratory session designed to induce stress in which they were asked to report on their PA and NA throughout the laboratory study. Patients in the M group exhibited dampened negative and positive affective reactivity to stress, and sustained PA at recovery, compared to the P and E groups. PA increased in response to induced stress for all groups, suggesting an "emotional immune response." History of recurrent depression increased negative affective reactivity, but did not predict reports of PA. RA patients who underwent a pre-intervention laboratory study showed less reactivity to stressors for both NA and PA during the post-intervention laboratory study. The M intervention demonstrated dampened emotional reactions to stress and lessened loss of PA after stress induction, displaying active emotion regulation in comparison to the other groups. These findings provide additional information about the effects of mindfulness on the dynamics of affect and adaptation to stress in chronic pain patients.
