Description
Using a sample of 931 undergraduate students, the current study examined the influential factors on undergraduate students' academic performance, satisfaction, and intentions to persist in their enrolled major. Specifically, the current study investigated the salience of interest-major match in predicting academic success. Interest-major match has been found to be one of the most influential determinants of academic and occupational success. However, support for this relationship has been equivocal and modest at best. The present study was designed to improve upon the current understanding of this relation by examining the moderating effect of gender and employing a longitudinal design to investigate the reciprocal relation between interest-major match and academic outcomes. Correlational results suggested that women reported greater interest-major match and results of the path analyses demonstrated a moderating effect of gender. Although a reciprocal relation was not supported, the findings indicated that a student’s level of academic satisfaction may influence the degree of fit between his or her interest and academic major. The results also highlight the tendency for students further along in their academic tenure to persist to graduation despite poor fit. Implications for educators and administrators are discussed.

Description
Sociopolitical involvement has been previously shown to be associated with experiences of discrimination. Lesbian, gay, and bisexual (LGB) racial/ethnic minorities have faced multiple levels of discrimination from the mainstream community, racial/ethnic minority communities, and LGB communities. However, not many studies have investigated the association between intersectional forms of discrimination and sociopolitical involvement. The present study examines differences in perceptions of racism in the LGB community, sociopolitical involvement in racial/ethnic communities, and sociopolitical involvement in LGB communities among LGB racial/ethnic minorities (N = 203, MAge = 27.25). The sample included 107 (52.7%) men and 96 (47.3%) women; 41 (20.2%) lesbians, 89 (43.8%) gay men, and 73 (36.0%) bisexuals; 47 (23.2%) African Americans, 50 (24.6%) Asian Americans, 64 (31.5%) Latinos/as, and 42 (20.7%) from another race/ethnicity or mixed race. This study also looks at the association between perceptions of racism in the LGB community and sociopolitical involvement in racial/ethnic communities and/or LGB communities. Asian American participants reported perceiving higher levels of racism in the LGB community than Latino/a participants. No other differences in perceptions of racism in the LGB community were found between sexual orientation or by racial/ethnic group. No differences between racial/ethnic group or sexual orientations were found in sociopolitical involvement in racial/ethnic or LGB communities. When controlling for sexual orientation, gender, and race/ethnicity, perceptions of racism in the LGB community predicted sociopolitical involvement in racial/ethnic and LGB communities. By exploring correlates of discrimination from an intersectional perspective, this study provides a better understanding of the experiences of LGB racial/ethnic minorities.

Description
Given the continued increase in obesity rates in the United States, there has been growing research regarding factors related to obesity. Researchers have examined biological factors, such as set point theory, as well as various psychological factors such as motivation, self-efficacy, and eating styles. Taster-type, defined as how an individual experiences the perception of taste (particularly bitterness), is a recent area of research that has explored the potential relationship between this phenomenon and obesity. The current study examined whether taster-type impacted weight loss, along with secondary measures of BMI, waist circumference, and food neophobia, as well as taster-type’s impact on these measures over time. This study also examined the potential role of taster-type as a predictor of weight loss, independent of the psychological variables of motivation, self-efficacy, and eating styles. Ninety adult participants, consisting of 64 females and 19 males were recruited for this study. They were asked to diet for four weeks; 60 finished the full four weeks and completed psychosocial measures over two time periods. They were asked to record their food using an online food journal, attend weekly meetings for weigh-ins, and were given psychoeducational materials regarding factors affecting weight loss. The results indicated that taster-type was not a significant factor in BMI or waist circumference, but taster-type did interact with time to reveal that supertasters consistently lost weight across the four week dieting period while nontasters leveled off after Week 2. Additionally, both groups increased in food neophobia from the start of the dieting period to the end of Week 4. Consistent with previous research, motivation and self-efficacy predicted weight loss; however, taster-type did not increase the prediction of weight loss across the dieting period. This effect only occurred at Week 2. By Week 4, no psychosocial variables were significant predictors of weight loss.

Description
Despite the evidence that suicide risk assessment training is necessary only 40-50% of psychology programs offer risk assessment training (Granello & Juhnke, 2010). In the present study an online suicide risk assessment and safety plan training workshop for graduate students in the field of psychology was investigated. Participants were randomly assigned to the control condition (lecture) or the treatment condition (lecture + demonstration). Measures of declarative knowledge of suicide risk and protective factors, application to clinical scenarios, and risk assessment and management self-efficacy scales were administered before and after completion of the workshop. Two way repeated measures ANOVA's were conducted with repeated time measures to evaluate the Time X Condition interaction. While there was a significant main effect of time on all three dependent variables, there was no significant time X condition interaction. In contrast to predictions, the added component of a demonstration did not result in greater improvements in application to clinical scenario multiple choice questions or risk assessment and management self-efficacy. Post hoc moderation analysis revealed demonstration enhanced the effects of knowledge acquisition and assessment of clinical scenarios for individuals who reported the training was less relevant to their current work. Implications of findings and directions of further research are discussed.

Description
Positive psychology focuses on the promotion of well-being (Seligman, & Csikszentmihalyi, 2000). Positive psychology interventions (PPIs) have been developed to help facilitate the development of skills needed to flourish and current research suggests that PPIs can help individuals improve their happiness, reduce stress, and become more resilient (Lyubomirsky, King, & Diener, 2005). National surveys highlight that students in higher education are in dire need of interventions aimed at helping them cope with the negative impact of stress (Douce & Keeling, 2014; Marks & Wade, 2015). Research among the graduate student population is scant even though they report high levels of stress and work even more hours than undergraduate students (Wyatt & Oswalt, 2013). PPIs implemented in the graduate student population focus heavily on psychologically-based programs, like psychology and social work, whose students may already be receiving assistance in self-care (Botta, Cadet, & Maramaldi, 2015; Burkhart, 2014; Nelson, Dell'Oliver, Koch, & Buckler, 2001). Thus, this current study is a randomized controlled trial testing an online PPI, adapted from Achor's work in the business industry (2012, 2014), compared with an online informative stress group and a wait list control group among graduate students from various disciplines at a large, public university in the Southwest. Participants were administered pre-, post-, and three-month follow-up tests to determine the impact of the interventions on their levels of perceived stress, happiness, and resilience. A multivariate analysis of covariance (MANCOVA) was used with covariates of age, gender, race, program of study, and graduate level of study (masters versus doctoral). The main findings of the study included: the students in the PPI group reported significantly higher resilience at the end of the three weeks than did the students in the informative stress or wait list control groups, even though measures of happiness or perceived stress were not impacted; and students from psychologically based programs received the most benefit from treatment, especially from the PPI intervention. All findings, implications, and suggestions for future directions are discussed.

Description
Previous research indicates that survivors of Intimate Partner Violence (IPV) are at a greater risk of developing Posttraumatic Stress Disorder (PTSD) symptomatology. IPV survivors often use maladaptive coping strategies in response to IPV that place them at a higher risk for PTSD. Cultural gender roles/beliefs have been known to influence coping methods. Marianismo, a Latino/a gender role belief, has not been investigated in relation to IPV, coping strategies, and PTSD among Latinas. This study examined whether physical, psychological, or sexual abuse by a romantic partner, coping strategies, and Marianismo were associated with PTSD symptomatology among 157 college-aged Latinas. The participants completed an on-line survey that assessed IPV frequency, disengaged and engaged coping, Marianismo, and PTSD symptomatology. Hierarchical multiple regressions revealed that, regardless of IPV type, more IPV and disengaged coping strategies were the best predictors of PTSD symptomatology. Marianismo did not significantly moderate the relation between coping and PTSD. However, the strong zero-order correlation between disengaged coping and Marianismo indicated they were highly correlated variables. The study findings are consistent with previous research that suggested that coping strategies are culturally dependent on beliefs and gender role expectations. Latinas may use more disengaged coping strategies because these methods may be deemed more culturally appropriate and reflect Marianismo beliefs. Psychologists working with Latina IPV survivors need to develop culturally sensitive approaches to psychoeducation on IPV and coping strategies that empower these women within their cultural belief systems and reduce their PTSD symptomatology.

Description
Training for law enforcement on effective ways of intervening in mental health crises is limited. What is available tends to be costly for implementation, labor-intensive, and requires officers to opt-in. DEFUSE, an interactive online training program, was specifically developed to train law enforcement on mental illness and de-escalation skills. Derived from a stress inoculation framework, the curriculum provides education, skills training, and rehearsal; it is brief, cost-effective, and scalable to officers across the country. Participants were randomly assigned to either the experimental or delayed treatment control conditions. A multivariate analysis of variance yielded a significant treatment-by-repeated-measures interaction and univariate analyses confirmed improvement on all of the measures (e.g., empathy, stigma, self-efficacy, behavioral outcomes, knowledge). Replication dependent t-test analyses conducted on the control condition following completion of DEFUSE confirmed significant improvement on four of the measures and marginal significance on the fifth. Participant responses to BPAD video vignettes revealed significant differences in objective behavioral proficiency for those participants who completed the online course. DEFUSE is a powerful tool for training law enforcement on mental illness and effective strategies for intervening in mental health crises. Considerations for future study are discussed.

Description
Cancer survivors engaged in either six-week Internet-delivered mindfulness training or a usual-care control and were compared on the following outcome battery: The Hospital Anxiety and Depression Scale, the Profile of Mood States, the Pittsburgh Sleep Quality Index, and the Fatigue Symptom Inventory. Assessments were conducted before and after treatment and intervention compliance was monitored. Mindfulness treatments were delivered at a time and on a computer of the participants’ choosing. Multivariate analysis indicated that mindfulness training produced significant benefits on all measures (p < .05). Online mindfulness instruction represents a widely-accessible, cost-effective intervention for reducing psychological distress and its behavioral manifestations in cancer survivors, especially those who are unable to participate in in-person training.

Description
Although women of color have increased their presence in the workplace, many obstacles restricting career opportunities still exist. It is important that mental health professionals contribute in providing interventions to increase career opportunities for women of color. The purpose of this research is to add to the repertoire of interventions by studying the irrational career beliefs of Black women. This research utilizes the Believe It! program, an online career development program that focuses on altering irrational/maladaptive career beliefs that can prevent young females from pursuing career opportunities. An early study of Believe It! found it to be effective for Caucasian females, however the effects for minority females were less clear. The current study re-examined the effectiveness of Believe It! for minorities by altering the appearance of the animated character within the program. It was hypothesized that young African American women interacting with African American animated agents would display greater rationality in terms of career beliefs compared to young African American women interacting with Caucasian animated agents. Forty-four African American girls between the ages of eleven to fifteen were pre-tested with a battery of assessment devices addressing the irrationality of the girls' career beliefs. The measures included the Career Myths Scale, the Career Beliefs Inventory, the Occupational Sex-role Questionnaire, and the Believe It! measure. Four to eight days later, participants engaged in the online Believe It! Program; they were randomly assigned to either a matched condition (viewing the program with an African American animated agent) or a mismatched condition (viewing the program with a Caucasian animated agent). After completion of the intervention, participants were post-tested with the same assessment battery. MANCOVA and ANCOVA analyses showed that participants in the matched condition consistently benefitted from the matched intervention. Implications for this research are discussed.

Description
Adolescence is a tumultuous time, and for those with risk factors, it can be even more difficult. This study examined the relationships among intrinsic and extrinsic protective factors such as high self-esteem, high self-efficacy, mattering to others, positive sense of identity, and healthy peer relationships in female adolescents. Additionally, the current study assessed the impact of a positive youth development intervention designed for this particular population. The potential sample consisted of adolescent girls who were students at an alternative high school in the Southwestern region of the United States. Of the 25 girls at the school, 12 participated in the study and completed pre-test instruments measuring self-esteem, self-efficacy, mattering to friends and parents, identity distress, and relational aggression. The instruments were administered before and after a positive youth development intervention of which 10 of the 12 participants attended. The intervention, Girls Circle, consisted of activities designed to foster self-acceptance, identity formation, healthy friendships, and goal setting in adolescent girls. While the study's intervention did not result in significant changes over time, several important findings emerged. Self-esteem was positively related to both mattering to friends and mattering to parents. Likewise, a negative correlation was found between relational aggression and mattering to parents. Girls who felt they were more important to friends and family had higher self esteem and were less likely to engage in covert aggression tactics such as spreading rumors and maliciously excluding peers from their social groups. These results support the literature and highlight the important interconnection of social relationships and subjective well-being. Teachers, counselors, social workers, and other helping professionals who work with adolescents need to understand these relationships and use this understanding to design and implement interventions that will best serve at-risk girls, such as those in this study.
