Description
Depressive disorders are common among the general populations but are present at an even higher rate among college students. Some research suggests that new stressors during the transition to college may place young adults at increased risk of depressive disorders. In addition, depression in college students has been linked to a variety of risky behaviors such as alcohol use and risky sexual activity. Fortunately, research suggests that religiosity may act as a buffer and lead to lower levels of depressive symptoms and risky behavior. Current research has not adequately examined the relationship between religiosity, depression, and risky behavior among college students. In this study, depressive symptoms were measured using the 20-item Center for Epidemiological Studies Depression scale, while risky behaviors were measured using the section on risky sexual behavior from the Youth Risk Behavior Surveillance survey and the section on alcohol consumption from the Behavioral Risk Factor Surveillance System survey, both developed by the Centers for Disease Control and Prevention. Four questions frequently used in literature to measure critical behaviors and attitudes were used to assess participants' religiosity. It was predicted that engagement in risky behaviors would be associated with higher levels of depressive symptoms while increased religiosity would be associated with lower levels. Additionally, increased religiosity would be associated with lower levels of engagement in risky behavior. Multiple regression analyses revealed that risky behavior were not significantly associated with higher depressive symptoms, while higher church attendance was associated with lower depressive symptoms. Although not considered a risky behavior, ever being forced to have sex was associated with higher depressive symptoms. Linear regression analyses revealed that increased religiosity was associated with increased engagement in risky behavior. These findings suggest that while depressive symptoms and risky behaviors are prevalent among college students, religiosity may act as a buffer and lead to lower levels of depression and risky behavior. Limitations, implications, and future research are discussed.

Description
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.

Description
Researchers have found inconsistent effects (negative or positive) of social relationships on self-control capacity. The variation of findings may depend on the aspects of social relationships. In this study, rather than examining overall social relationships and self-control, characteristics in social relationships were clearly defined, including social support, social connection and social conflict, to determine their specific effects on self-control. An online survey study was conducted, and 292 college students filled out the survey. For data analysis, path analysis was utilized to examined the direct effect and indirect effect from social relationships to self-control. Results showed social connection and social conflict may indirectly associate with self-control through stress, but social support does not. It may suggest, in traditional stress buffering model, it is the social connection in social support that really reduce the stress. Concerning the direct effects, social support and social connection were significantly associated with self-control directly, but social conflict does not. This result may support the Social Baseline Theory that positive social relationships have direct regulating effects. Results are good for guidance of experimental manipulation of social relationships in study of social influences of self-control.

Description
As many as one-third of OEF/OIF soldiers and combat veterans may be struggling with less visible psychological injuries. Military/veteran students may face heightened difficulties as they are not only adjusting to civilian life but also transitioning to college life. University administrators and staff have been charged to address their transitional needs and to promote their academic success. Despite significant influx in enrollment with the passing of the Post-9/11 GI Bill, research on OEF/OIF service members and veterans in higher education remains limited. Utilizing self-report measures, the current study examined the psychosocial functioning of 323 military/veteran students enrolled at Arizona State University who served at least one combat deployment as part of OEF/OIF. The study further investigated whether enlisting for educational benefits and utilizing campus programs/services were associated with more positive academic persistence decisions. Participants were also asked to rate ASU's programming for military/veteran students as well as suggest campus programs/services to promote their academic success. More PTSD symptoms, depression, anxiety, and anger/aggression were found to be associated with less cultural congruity and lower perceived social support. Cultural congruity and social support were significant predictors of academic persistence decisions. Participants who reported utilizing more campus programs/services also tended to endorse more positive persistence decisions. No significant differences in persistence decisions were found between participants who enlisted in the military for education benefits and those who enlisted for non-educational reasons. Approximately two-thirds reported utilizing academic advising services and Veteran Benefits and Certifications. Library services, financial aid services, and ASU sporting events were the next most frequently utilized. More than 91% rated ASU's programming satisfactory or better. Over 71% of participants indicated that increasing recognition of their military experience would facilitate their academic success. Nearly 40% recommended a military/veteran student lounge and improvements to VA education benefits counseling. Another 30% recommended that ASU provide professional development for faculty/staff on military/veteran readjustment issues, improve the re-enrollment process following deployment/training, offer a veteran-specific orientation, and establish a department or center for military/veteran programming. Findings are discussed in light of Tinto's interactionist model of college student attrition, and implications for university mental health providers are presented.

Description
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.

Description
Literature was reviewed about how synchrony occurs in infant-parent dyads, in emotion, and physiologically in couple dyads. Social baseline theory suggests that both conversation and interpersonal touch confer benefits by reducing burden on the participants through coregulatory processes. The current study examined how affectionate touch and positive conversation influenced physiological synchrony, a potential mechanism of physiological coregulation, in couples. Because synchrony is believed to occur within the autonomic nervous system, in the present study, physiological synchrony was measured using cardiac interbeat interval (IBI) as an indicator of autonomic nervous system activation. Couples were assigned to one of four conditions: interpersonal touch with positive conversation, interpersonal touch without conversation, positive conversation with no interpersonal touch, and neither interpersonal touch nor conversation. We hypothesized that 1) IBI synchrony between spouses within the real data would be significantly higher than within a phase-shuffled version of the data; and 2) synchrony would be strongest in the touch-talk condition, followed by the touch-no talk condition, followed by the talk-no touch- condition, and finally by the no touch-no talk condition. We also investigated whether there was a tendency for husbands or wives to serve as leader or follower in the four conditions. Using windowed lagged cross-correlations, we found that synchrony within the real data was stronger than synchrony within the shuffled data, suggesting that it reflects an ongoing interpersonal process. Next, we found that there was significantly greater synchrony in the touch-talk than in the touch-no talk condition, marginally greater synchrony in the touch-no talk condition than in the no touch-talk condition, and significantly greater synchrony in the no touch-talk than in the no touch-no talk conditions, suggesting that talk, rather than touch, was driving these synchrony levels. We also found that the only condition with a significant level of leading-following pattern was the no touch-talk condition. More husbands than wives led the covariation in IBI when couples were conversing but not touching. When touch was included this effect did not occur. Future research should include potential moderators such as marital satisfaction and investigate whether seeing one’s partner influences synchrony.

Description
The rates of anxiety, depression, and attempted suicide for transgender individuals are extremely elevated relative to the general population. Yet, little research has been conducted about the transgender population regarding social transition (an individual presenting as their authentic/true gender, one different than the gender they were assigned at birth, in the context of everyday life) and parental acceptance. Both of which have been shown to impact the mental health of transgender individuals. The purposes of this study were: (1) To characterize a sample of transgender adults on their age of awareness of their authentic gender identity and their age of social transition. (2) Examine whether age of social transition, (3) parental acceptance, and (4) the gap in time between age of awareness and age of social transition (awareness-transition gap) were related to mental health. (5) Examine whether parental acceptance was related to age of social transition or to awareness-transition gap. (6) Examine whether age of social transition or awareness-transition gap interact with parental acceptance as correlates of mental health. The sample consisted of 115 transgender adults, ages 18 to 64. Measures were separated into 7 subheadings: demographics, transgender
on-cisgender identity, age of awareness, age of social transition, primary caregiver acceptance, secondary caregiver acceptance, and mental health. Hypotheses were partially supported for age of social transition with mental health, parental acceptance with mental health, and awareness-transition gap with parental acceptance. This study investigated under studied concepts of social transition and parental acceptance that appear to have an effect on the mental health of transgender adults.

Description
The goal of my study is to test the overarching hypothesis that art therapy is effective because it targets emotional dysregulation that often accompanies significant health stressors. By reducing the salience of illness-related stressors, art therapy may improve overall mood and recovery, particularly in patients with cancer. After consulting the primary literature and review papers to develop psychological and neural mechanisms at work in art therapy, I created a hypothetical experimental procedure to test these hypotheses to explain why art therapy is helpful to patients with chronic illness. Studies found that art therapy stimulates activity of multiple brain regions involved in memory retrieval and the arousal of emotions. I hypothesize that patients with chronic illness have a reduced capacity for emotion regulation, or difficulty recognizing, expressing or altering illness-related emotions (Gross & Barrett, 2011). Further I hypothesize that art therapy improves mood and therapeutic outcomes by acting on the emotion-processing regions of the limbic system, and thereby facilitating the healthy expression of emotion, emotional processing, and reappraisal. More mechanistically, I propose art therapy reduces the perception or salience of stressors by reducing amygdala activity leading to decreased activation of the hypothalamic-pituitary-adrenal (HPA) axis. The art therapy literature and my hypothesis about its mechanisms of action became the basis of my proposed study. To assess the effectiveness of art therapy in alleviating symptoms of chronic disease, I am specifically targeting patients with cancer who exhibit a lack of emotional regulation. Saliva is collected 3 times a week on the day of intervention: morning after waking, afternoon, and evening. Stress levels are tested using one-hour art therapy sessions over the course of 3 months. The Perceived Stress Scale (PSS) assesses an individual's perceived stress and feelings in past and present situations, for the control and intervention group. To measure improvement in overall mood, 10 one-hour art sessions are performed on patients over 10 weeks. A one-hour discussion analyzing the participants' artwork follows each art session. The Spielberger State-Trait Anxiety Inventory (STAI) assesses overall mood for the intervention and control groups. I created rationale and predictions based on the intended results of each experiment.

Description
Sibling interactions are natural contexts for learning about the appropriate expression of emotions. The emotionally charged nature of sibling interactions creates a convenient context to explore emotional reactivity and regulation. The purpose of this study was to examine the relations among parent-reported sibling relationship quality, observed sibling prosocial and antisocial behaviors displayed when playing a competitive marble game, and children's emotions coded from videotape. The sample consisted of 58 twin children who are currently participating in the longitudinal Arizona Twin Project. Parents completed the Sibling Relationship Questionnaire online at 5 and 8 years. Additionally, a competitive marble game interaction between the siblings took place in the home at 8 years and was videotaped for objective coding of prosocial, antisocial, and control behavior. Facial expressions were also coded from videotape using Emotient FACET software across the marble game interaction. Three mean composites of emotion were created, including positive and negative emotional facial expressions. Results showed that parent reported warmth did not predict the occurrence of positive emotions during the sibling interaction. However, siblings with high conflict showed less fear during the interaction. Parent reports of warmth predicted the extent to which siblings differed on emotion expression, however conflict did not. Parent ratings of conflict and warmth did not predict the extent to which the sibling dyad was emotionally intense. Findings regarding genetic and environmental effects were in line with previous reports of genetic influence on prosocial behavior and negative emotion, and expressions of joy being influenced by the environment. This study investigated noteworthy aspects of the sibling relationship that appear to promote children's adaptive development.

Description
It is a well-established finding in memory research that spacing or distributing information, as opposed to blocking all the information together, results in an enhanced memory of the learned material. Recently, researchers have decided to investigate if this spacing effect is also beneficial in category learning. In a set of experiments, Carvalho & Goldstone (2013), demonstrated that a blocked presentation showed an advantage during learning, but that ultimately, the distributed presentation yielded better performance during a post-learning transfer test. However, we have identified a major methodological issue in this study that we believe contaminates the results in a way that leads to an inflation and misrepresentation of learning levels. The present study aimed to correct this issue and re-examine whether a blocked or distributed presentation enhances the learning and subsequent generalization of categories. We also introduced two shaping variables, category size and distortion level at transfer, in addition to the mode of presentation (blocked versus distributed). Results showed no significant differences of mode of presentation at either the learning or transfer phases, thus supporting our concern about the previous study. Additional findings showed benefits in learning categories with a greater category size, as well as higher classification accuracy of novel stimuli at lower-distortion levels.
