Abuse subtypes and nonsuicidal self-injury: preliminary evidence of complex emotion regulation patterns.

Research has identified complex relationships between abuse experiences, emotion regulation, and nonsuicidal self-injury (NSSI). Data generally indicate that individuals with an abuse experience, or those with NSSI, have difficulties with emotion regulation. However, it is unknown whether there are specific patterns of emotion regulation difficulties across abuse subtypes that are uniquely associated with engaging in NSSI. Using a sample of 2238 college students (n = 419; 18.1% with NSSI histories), the present study examined differences in emotion regulation difficulties across specific abuse types between those with and without a history of NSSI. Results indicate significantly greater difficulties with emotion regulation among abused and self-injuring participants as well as significant differences on specific emotion regulation problems between self-injuring and noninjuring participants within the physical abuse and combination physical/sexual abuse subtypes. Possible explanations and implications of these findings are discussed.

Learning effects in the block design task: a stimulus parameter-based approach.

Learning effects were assessed for the block design (BD) task, on the basis of variation in 2 stimulus parameters: perceptual cohesiveness (PC) and set size uncertainty (U). Thirty-one nonclinical undergraduate students (19 female) each completed 3 designs for each of 4 varied sets of the stimulus parameters (high-PC/high-U, high-PC/low-U, low-PC/high-U, and low-PC/low-U), ordered randomly within a larger set of designs with mixed stimulus characteristics. Regression analyses revealed significant, although modest, learning effects in all conditions. Negative-logarithmic learning slopes (growth factors) were greatest for high-U/high-PC designs and smallest for low-U/low-PC designs. Comparison of these slopes with known Wechsler Adult Intelligence Scale (3rd ed.; D. Wechsler, 1997; and 4th ed.; D. Wechsler, 2008) BD subtest gain scores demonstrated that presenting novel test items matched on stimulus parameters in multiple administrations reduced learning effects compared with the repeated use of the same test items. The results suggest that repeated administration of novel test items of the BD subtest, matched for PC and U, would result in more accurate assessments of changes in examinees' abilities over time than would the use of the same items. Difficulties inherent in implementing this method are also discussed.

An evaluation of a mixed-gender sexual assault prevention program.

This study evaluated the short-term effectiveness of a mixed-gender sexual assault prevention program developed for college students. Program participants (n = 177) were compared to non-program participants (n = 132) prior to the program and during a 2-week follow-up period on measures of rape myths, victim empathy, perceived negative consequences and estimated likelihood of committing rape, sexual communication, sexual assault awareness, and risky dating behavior. The prevention program was effective at increasing men's victim empathy and decreasing their adherence to rape myths but ineffective at changing women's assault-related knowledge, participation in risky dating behaviors, and sexual communication strategies. Limitations of the study and directions for future research in sexual assault prevention are addressed. Editors' Strategic Implications: This study provides an important example of the limitations of a single session prevention programming approach (even if it is well designed and executed) in addressing a systemic and pervasive problem like sexual assault on college campuses.

Sexual assault prevention with college-aged women: a bibliotherapy approach.

The present research evaluated the efficacy of a skills-based bibliotherapy approach to sexual assault prevention for college-aged women. One hundred and ten participants were followed prospectively for 16 weeks. A self-help book, written by the authors, was compared to a wait-list control on several self-report measures. Results revealed significant differences between groups, with bibliotherapy participants reporting decreased participation in risky dating behaviors and improvement in sexual communication strategies across a variety of dating situations. However, results suggested that the self-help book was no more effective than the wait-list control in reducing rates of sexual victimization. Limitations of the study and directions for future sexual assault prevention research with women are discussed.
