Do So

Little prior research has empirically examined anonymity in learning. In this study, we manipulated learner identity by experimentally assigning learners to participate in online discussion either anonymously or using their actual name, crossed with learning medium (OpenSim/Second Life vs. real-time chat), with the goal of determining if anonymous discussion in multi-user virtual environments (MUVE) provides unique value to learning (a 2x2 between-subjects design). Results from a quantitative hierarchical multiple regression analysis revealed both main effects: participants who were anonymous scored lower (d = -0.46) and participants discussing in a MUVE scored lower (d = -0.47) on the learning measure without interactive effect, suggesting that anonymizing participants during content-related discussion may reduce learning under certain circumstances. The authors suggest instructors encourage learners to represent themselves authentically in any VEs to maximize learning and also discourage instructors from adopting MUVEs if their only reason to do so is to host synchronous discussion.

Positive Correlations

Positive psychological characteristics and executive function are correlated with gratitude, satisfaction with life, and forgiveness. The goal of this study was to replicate these findings while examining two additional constructs, namely, hope and optimism. 113 students (25 men, 88 women) between the ages of 17 to 24 years ( M = 19.4, SD = 1.5) volunteered to participate. Positive correlations between executive function and gratitude were found but mixed results were obtained for forgiveness and satisfaction with life. Hope and optimism correlated positively with executive function and hierarchical multiple regression analysis indicated that they contributed significantly to the explanation of executive functioning. Further investigation into relationships between executive functioning, its neurobiological substrates, and positive psychological attributes is recommended.

Stratified Sample

Correlates of sexual satisfaction were identified in a sample of older married women. A 70-item questionnaire was mailed to an age-stratified sample of 5,000 married persons, including 1,000 married women over the age of 50. Usable questionnaires were received from 148 participants (14.8% return rate). Hierarchical multiple regression analysis, using sexual satisfaction as the dependent variable, yielded five predictor variables that accounted for a significant portion of the variation in sexual satisfaction (Cumulative R2 = .73). These results serve as a reminder that sexual interactions cannot be compartmentalized but must be considered within the context of the overall marriage relationship. Given the low return rate, interpretations should be limited until replication with an adequate sample has been completed.

Revised Neo Personality Inventory

The hypothesis that the MMPI–2 Psychopathology–5 scales are better predictors of personality disorders than the Revised NEO Personality Inventory scales was tested using Personality Adjective Checklist personality disorder scales with a 9-point response format. The three inventories were completed by 258 introductory psychology students (113 men and 145 women) for partial course credit. Hierarchical multiple regression analysis was performed for predicting each Personality Adjective Checklist scale by entering the Revised NEO Personality Inventory scales as a set in the first step and the Psychopathology–5 scales as a set in the second step. Incremental validity of the Psychopathology–5 scales over the Revised NEO Personality Inventory scales for predicting each Personality Adjective Checklist scale was measured by the R2 change at the end of the second step in the hierarchical multiple regression analysis. Incremental validity values ranged from .01 to .09, with a median of .03, and were significant for only five Personality Adjective Checklist scales. Such results provided very little support for the hypothesis of relative superiority of the Psychopathology–5 scales over the Revised NEO Personality Inventory domain scales for predicting personality disorders.

Willingness To Forgive

43 graduate students' willingness, within a hypothetical situation, to forgive a friend whose negligent actions negatively affected their chances of getting a job was examined. Self-actualization, age, and general interpersonal closeness were proposed as possible variables related to these students' ratings of willingness to forgive while-controlling for sex. A hierarchical multiple regression analysis showed this model predicted 23% of the variability in Forgiveness scores using self-actualization and age as significantly related to forgiveness in a positive direction, but with sex and general interpersonal closeness showing no significant relation.

Cue Words

Specificity and categoric descriptions of autobiographical memories (AM) are reported to be psychological trait markers for vulnerability for depression. Thus, they should permit the prediction of future affective changes. Fifty pregnant women were tested for their recall of AM as well as twice—during pregnancy and 3 months after delivery—with the Edinburgh Postnatal Depression Scale (EPDS; Cox, Holden & Sagovsky, 1987 ). The main scope of the study was the evaluation of the potential of AM in predicting affective changes in a nonclinical sample of women following childbirth. Using a hierarchical multiple regression analysis, categoric descriptions in response to negative cue words allowed a significant prediction of affective changes.

Tattooing has become more acceptable in the mainstream American culture in recent years. Based on a survey with face-to-face interviews of 335 nontattooed adults randomly selected from a city with a population of 444,000, this study explored the relationship of individuals' demographic variables, attitudes toward religion, and their perceptions of tattoos. The hierarchical multiple regression analysis showed that age and attitude toward religion were associated with individuals' perception of tattoos.

The Relationship

Despite the advocacy of a confidence-enhancing function of mental imagery, the relationship between confidence and imagery has received little attention from sport researchers. The primary purpose of the present study was to identify the specific image content of confident athletes. Fifty-seven elite competitive rollerskaters completed the Movement Imagery Questionnaire-Revised (MIQ-R), the Sport Imagery Questionnaire (SIQ), and the State Sport Confidence Inventory (SSCI). Results revealed that high sport-confident athletes used more mastery and arousal imagery, and had better kinesthetic and visual imagery ability than low sport-confident athletes did. A hierarchical multiple regression analysis revealed that mastery imagery accounted for the majority of variance in SSCI scores (20%). The results of this study suggest that when it comes to sport confidence, the imaged rehearsal of specific sport skills may not be as important as the imagery of sport-related mastery experiences and emotions.

Perceptions Of Safety

Abstract Background Hospital accreditation programs can positively affect nurses’ perceptions of patient safety culture. However, no previous research has identified the association between experience of hospital accreditation and nurses’ perception of patient safety culture in general hospitals. This study aims to examine 1) the level of perception of each area of patient safety culture in nurses working in general hospitals and 2) the relationship between experience of hospital accreditation and nurses’ overall perceptions of safety in Korean general hospitals. Methods A cross-sectional survey design was used, with a convenience sample of 310 nurses from six general hospitals. Nurses were asked to complete the self-reported Korean version of the Hospital Survey on Patient Safety Culture and the experience of hospital accreditation. A hierarchical multiple regression analysis was used to examine the associations between hospital accreditation experience and perception of patient safety culture. Results The patient safety composites with the highest positive response were the frequency of events reported (90.6) and supervisor/manager expectations promoting patient safety (69.4%). The composites with the lowest scores were non-punitive responses to errors (22.9%) and organizational learning/continuous improvement (35.5%). Hierarchical multiple regression analysis showed that the experience of hospital accreditation had a very small increase on overall perceptions of safety (β = 0.097, p = 0.023). Conclusions This study found that general hospital nurses’ experience of hospital accreditation had very weak relationship with their overall perceptions of patient safety. Therefore, a longitudinal study is needed to confirm the influence of hospital accreditation on nurses’ patient safety culture in general hospitals.
