Description
This study examined four research questions investigating relationships among the experience of trauma, identity development, distress, and positive change. There were 908 participants in the study, ranging in age from 18 to 24 which is known as the period of emerging adulthood. Participants completed an online survey regarding their exposure to trauma and reactions to these experiences. The first research question examined the experience of trauma for the sample. The second question examined group differences among the participant's identity status, gender, and posttraumatic stress disorder (PTSD) diagnostic status on the hypothesized variables. In general, comparisons among the four identity status groups found participants who experienced greater identity exploration (diffused and moratorium) experienced more distress, whereas the identity status groups that reported greater identity commitments (foreclosed and achieved) were associated with positive change. Similar findings were found for PTSD diagnostic status indicating more distress and identity exploration for participants with the diagnosis and more positive change and identity commitments for participants without the diagnosis. Female participants were found to experience more PTS symptoms, centrality of the trauma event, and positive growth than males. Examination of the relationships between trauma severity and posttraumatic growth revealed an inverted U-shaped relationship (quadratic) that was a significant improvement from the linear model. An S-shaped relationship (cubic) was found for the relationship between trauma exposure and posttraumatic growth. Regression analyses found the centrality of the trauma event to one's identity predicted identity distress above and beyond the experience of trauma. In addition, identity distress and the centrality of the trauma contributed to the variance for identity exploration, while only identity distress contributed to identity commitments. Finally, identity development significantly predicted positive change above and beyond, identity distress, centrality of the trauma event, and the experience of trauma. Collectively, these results found both distress and growth to be related to the experience of trauma. Distress within one's identity can contribute to difficulties in the psychosocial stage of identity development among emerging adults. However, the resolution of identity exploration towards commitments to goals, roles, and beliefs, can help trauma survivors experience resilience and growth after stressful experiences.

Over recent decades, euthanasia has been a topic of increasing debate. With legalization of euthanasia in the states of Oregon and Washington and attempted reform in several other U.S. states and nations worldwide, it has become increasingly important to understand the roles and values of helping professionals who might be working with clients considering this option. The current study targeted 85 undergraduate students, 54 doctoral students in counseling psychology, and 53 doctoral-level professionals in psychology to assess both their personal values regarding euthanasia and their willingness to allow a client the autonomy to make a decision about euthanasia. Several factors were analyzed in regards to their relation to client autonomy and attitudes toward euthanasia, including age of client and sex of client. These variables were manipulated in vignettes to create four scenarios: a 24 year old male, 24 year old female, 80 year old male, 80 year old female. Other factors included level of education of the participant, spirituality and strength of religiosity of the participant, and personal experiences with deaths of friends or family members. Results indicated that more education was associated with greater support for euthanasia and that stronger religiosity and spirituality were related to less support for euthanasia. This study also found that participants did not exhibit differential levels of support based solely on the age or the sex of the client depicted in the vignette. Results further indicated that for doctoral students and professionals the loss of a loved one, regardless of cause of death, did not have a significant effect on their attitudes toward euthanasia. It is important for training programs to be aware of these findings in order to monitor trainees in terms of personal biases in the therapy relationship. With objectivity a high priority while working with clients, it is necessary to be aware of outside factors potentially influencing one's work with clients surrounding this value-laden issue.

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.

ABSTRACT
While the cross-cultural literature on body dissatisfaction among Mexican and Mexican-American women has continued to grow, the traditional Latino female gender role of marianismo, sociocultural factors related to ethnic culture and mainstream/American culture ideal perceived discrepancies in body size, and one’s romantic relationship have not been explored with this population in relationship to body satisfaction. The current study included 227 female participants predominantly from a large southwestern university in the United States and a large university in northern Mexico. The study examined differences in marianismo and body satisfaction between 120 Mexican and 107 Mexican-American women, investigated the role of marianismo as a mediator between weight-related teasing and body satisfaction, and explored the relationship between marianismo, Partner Ideal Discrepancy, Ethnic Culture Ideal Discrepancy, Mainstream/American Culture Ideal Discrepancy, Perceived Weight-Related Criticism/Teasing, Relationship Support, Relationship Depth, and Relationship Conflict to overall body satisfaction. Results indicated Mexican-American women endorsed less overall body satisfaction than did their Mexican counterparts suggesting that Mexican American women may be more influenced by societal messages about thinness and beauty than are Mexican women. The findings also revealed a possible trend for marianismo as a mediator between weight-related criticism and body satisfaction. Marianismo and weight-related teasing were found to have a negative relationship with body satisfaction. Multiple regression analyses revealed that Partner Ideal and Mainstream/American Culture Ideal discrepancies accounted for significant variance in body satisfaction. Relationship Conflict accounted for a smaller but still significant amount of the variance in body satisfaction. Ethnic Culture Discrepancy, Relationship Support, and Relationship Depth were not significant predictors. These findings from this study suggest that both cultural variables and romantic relationship variables are related to the body image of Mexican American and Mexican women. These findings have important implications for the adaptation of current etiological models explaining body satisfaction among Mexican and Mexican-American women as well as highlighting the need to consider the role of both cultural and relationship variables in designing clinical interventions for Mexican American and Mexican women coping with body image concerns.
