This study examined the relationships between coping and positive affect and sex differences in those relationships, focusing on emotional expression as an emotion-focused coping strategy. Undergraduates (193 men and 225 women) completed the Center for Epidemiologic Studies-Depression to assess positive affect by using the Positive Affect subscale and the General Coping Questionnaire for measurement of coping. Analysis showed a positive relationship between positive affect and both problem-solving and cognitive reinterpretation, but only for men, while a positive relation between positive affect and emotional expression was found only for women. Also there were no interactions of emotional expression and other coping strategies, such as problem-solving, cognitive reinterpretation, and emotional support-seeking, on positive affect. These findings provide evidence to suggest that the relationship between positive affect and coping should be examined by sex.

Using a national sample of business professionals, the relationship between two measures of perceived organizational ethics and individuals' overall skepticism about women's employment were examined. After controlling for several demographic factors, analysis of responses from a 9% return suggested that persons working for companies believed to have strong ethical practices are less likely to have negative perceptions of women's employment.

To identify sex differences in boredom proneness, 146 undergraduates (66 men and 80 women) were asked to complete the Boredom Proneness Scale. An independent groups t test indicated a statistically significant mean difference in boredom proneness as men scored significantly higher than women.

This study examined relationships between academic cheating behaviors by using self-reports of past cheating behavior, providing a situational experiment with the opportunity to cheat, and evaluating defense mechanisms and object relations as measured by the Defense Mechanisms Inventory. Subjects included 75 female and 8 male university students ranging in age from 18 to 51 years (M = 25.5, SD = 6.9). Analysis showed variations in students' self-reported cheating history relative to their measured object relations status and type of defense mechanisms. Actual cheating in the experimental setting was not significantly related to any of these variables. Findings are discussed based on a critique of heterogeneity of the cheating construct.

This study examined the underlying dimensions of the Pay Satisfaction Questionnaire to test whether the robust 4-factor structure (Pay Level, Benefits, Raises, and Structure or Administration) often established in the United States can be generalized to other countries and cultures as well. Data of 4 samples (for-profit employees, nonprofit nurses, cultural centre employees, and nonprofit teachers) were analysed with confirmatory factor analyses. The results for the first 3 samples yielded support for the original 4-factor structure of the Pay Satisfaction Questionnaire. In the teachers' sample, the irrelevant Benefits items were excluded from the analysis, resulting in a 3-factor structure of pay satisfaction.

The hallucinogenic “designer drug” known as Foxy or Methoxy Foxy and formally know as 5-Methoxy-N,N-di(iso)propyltryptamine hydrochloride (5-MeO-DIPT) is rapidly gaining popularity among recreational users. However, little is known about the consequences of its use on neuropsychological development or behavior. During one of two adolescent periods, the rats were given repeated injections of either saline or 5 mg/kg of 5-MeO-DIPT. Once the animals reached 80 days of age, they were trained and tested on a number of tasks designed to assess the effects of 5-MeO-DIPT, if any, on memory tasks with spatial components that presumably involve declarative memory systems and on a nonspatial task that is considered sensitive to disruptions in nondeclarative memory. With one exception, both the 5-MeO-DIPT-and saline-treated rats were able to master the spatial navigation tests at comparable rates. However, the performance of the drug-treated rats was markedly inferior to that of the control animals on a response-learning task, suggesting a lack of flexibility in adapting their responses to changing task demands. This could indicate reductions in serotonin activity in the forebrain similar to the effects of studied drugs such as methylenedioxymethamphetamine (MDMA), suggesting 5-MeO-DIPT may act as a toxin compromising serotoninergic systems in the brain.

Several studies have suggested there is a developmental link between executive functions and theory of mind. However, the developmental order driving the relationship is not well understood. The main reason is that the development of executive function parallels the development of theory of mind in normally developing children. In this paper, a case (H.Y.) is reported. H.Y. had lived in a persistent vegetative state for 6 years after encephalitis at the age of 10. He showed a developmental order driving the relationship between executive functions and theory of mind. These findings are consistent with recent suggestions that development of executive function might be important as a predecessor of either the ability to understand false beliefs or the ability to express that understanding.

Consistent with evidence from several recent geographical (cross-national and within-nation) studies (by Lester and by Voracek), a positive ecological (aggregate-level) correlation of regional intelligence and suicide rate was found across the seven major geographical regions of Denmark.

The association of total study time, number of events, time per event ratio, study strategies, and course grades across the semester were examined by linking students' study logs to course performance. There were 37 upper-division and 109 lower-division participants. Students earning As and Bs studied more frequently at the end of the semester but for shorter periods of time than students earning lower grades. Results are discussed in terms of providing college students and faculty with recommendations about learning strategies and time spent studying.

“What makes your life meaningful?” is a question previous researchers explored with people of various ages, but not of individuals who have significant physical impairments. In this study, 26 individuals with physical disabilities were asked to describe what makes their lives meaningful. Analysis showed human relationships were the most frequently reported source of meaning in life, the sources being family members, friends, and people in the community. The second most frequently cited meaning was service, specifically, helping and educating others, such as other people with physical disabilities.

Moral reasoning should not be clearly associated with measures of personality traits. Although this assumption pervades the moral reasoning literature, it may not always be true. This paper provides evidence that moral reasoning, as assessed with P scores of the Defining Issues Test, is indeed positively associated with five traits from the California Psychological Inventory: Achievement via Independence, Intellectual Efficiency, Tolerance, Responsibility, and Capacity for Status. Such relationships make conceptual sense, shed light on the meaning and implications of moral reasoning, call into question prevailing assumptions in the literature, and may encourage investigators to broaden the types of research questions asked in the context of moral reasoning.

This study investigated the relationship between body-esteem and self-esteem among 215 young men and women (ages 18 to 25 years). It was expected that concern with weight and shape would be strongly associated with women's self-esteem, while men's self-esteem would be more closely linked to concerns about their fitness. Multiple regression analyses indicated that perceived attractiveness and the salience of weight and shape were significant predictors of self-esteem among women. Among men, the significant predictors of self-esteem were perceived attractiveness, body disparagement, and perceived strength and fitness.

Prior attempts to condition a one-celled organism, paramecium, by either classical or instrumental procedures have yielded both positive and negative results. As the results of those studies may be subject to several interpretations other than one indicating learning, it was decided to use a more traditional technique for the present study. This experiment was designed to assess whether aversive electric shock could be used to train paramecia on a brightness discrimination task, a procedure that has been used in animal learning research. The results indicated that such learning may have occurred.

Death anxiety was assessed in two groups, one during the civil war in Lebanon (1986) and one after the cessation (1991). For two samples (n₁ = 673, n₂ = 616) of Lebanese male and female secondary school and university students no significant mean between-group (time) differences were found. However, the females had higher mean scores on death anxiety in all comparisons

The Visual Similes Test II was designed to measure the construct of arousal. This study investigated its factor structure with scores from a sample of 154 African-American elementary school children (7 to 10 years). The initial factor structure was examined using principal axis factor analysis with the promax rotation. Confirmatory factor analysis was then used to evaluate the model-fit of the data with the hypothesized hierarchical model. Results provided support for the two-factor structure in the principal axis factor analysis and the model-fit of the hypothesized model in the confirmatory factor analysis.

This study examined the validity of Experiential and Reflective Self-knowledge Scales in a sample of Iranian factory workers. Both scales were administered to 321 male and 12 female workers (M age = 35.6 yr., SD = 8.9) along with the Basic Need Satisfaction at Work Scales, the Work Climate Questionnaire, and measures of Perceived Stress and Self-esteem. Scores on the two self-knowledge measures correlated with all other variables consistent with the claim of Self-determination Theory that self-insight is associated with a more complete satisfaction of basic needs. In a number of multiple regression analyses, Reflective and Experiential Self-knowledge combined to explain variance in other measures. These data further supported the validity of the two new Self-knowledge Scales.

In a sample of 112 Kuwaiti college students, approval of physician-assisted suicide was not significantly correlated with scores on trait anxiety, death depression, or death obsession.

The study examined the relationship between ethnic identity and risky health behaviors in 1,892 Mexican-American students (M age=14.6, SD = 1.35; 50.3% male) in South Texas. The Ethnic Identity Scale assessed ethnic identity and questions from the Youth Risk Behavior Survey measured risky health behaviors (mixed use of alcohol and drugs, heavy drinking, driving under the influence, regular marijuana use, regular cigarette smoking, lack of regular exercise, not eating breakfast regularly, and carrying a gun or knife to school). Logistic regression tested the relationships between ethnic identity and report of risky health behaviors controlling for potential confounders (sex, free school lunch status, grade, and self-reported school grade). Adjusted odds ratio (AOR) and confidence intervals were calculated. Results indicated that being associated with Mexican-American cultural identity was significantly associated with a decreased mixed use of alcohol and drugs (AOR=.97), heavy drinking (AOR=.98), and regular marijuana use (AOR=.97). A stronger ethnic identity was protective against engaging in risky health behaviors among these Mexican-American adolescents.

Participants, taking classes that met general learning requirements, were 133 men and 240 women from two private, Catholic, liberal arts college campuses. The sample consisted of 131 first-year students, 91 sophomores, 70 juniors, and 81 seniors. The sample was 95.2% Euro-American, consistent with the populations of these campuses, and 98.1% were between 18 and 22 years old. There were five different survey packets. One packet asked participants to report how they coped with a self-selected situation from their own past (Standard Condition). The other four packets asked participants how they would cope with one of four vignettes developed by the researchers. Two vignettes described common social situations, and two described common academic situations a college student would find stressful. The packets were randomly distributed among participants. Several significant correlations between perfectionism and coping strategies were found for the 4 vignettes, but none were found under the Standard Condition. Were there a self-serving bias in participants' reports of past situations in which they remember coping successfully, correlations would be diminished between coping and perfectionism in the Standard Condition.

To understand better students' preferences for enrollment in distance education over face-to-face courses, the individual difference variables of sex, age category, class level, work status, number of distance education courses taken, frequency of computing technology usage, comfort with course management software, and comfort with computing technology were examined. Analysis indicated that older students, women, and those who work full time were more likely to enroll in distance education courses. Those who had taken the most distance education courses in the past and women were more likely to express a stated preference for distance education over face-to-face classes.

The study examined the judgments made by four seventh-grade mathematics teachers of their 107 students' competence in solving mathematics problems. Simultaneously, the 107 students made self-efficacy judgments about their capability in solving mathematics problems. The two sets of judgments were tested for predicting students' mathematics performance. Also, students' prior mathematics achievement was studied for its influence on both teachers' and students' judgments and students' mathematics performance. Teachers were asked to make judgments of each student for every mathematics problem solved. Results were consistent with prior research indicating that students' mathematics self-efficacy beliefs were highly predictive of their performance. Path analysis indicated that the mathematics teachers' judgments were also highly predictive of students' performance and self-efficacy. In turn, these variables predicted students' postperformance judgments. Combining students' self-efficacy judgments and teachers' judgments of students increased predictiveness for students' mathematics performance. Educational implications were also discussed.

In this study the detection of feigned memory impairments was investigated using a forced-choice task with Chinese words as stimuli. Task difficulty on accuracy and response time and the faking strategies employed were examined for 85 participants, 42 men and 43 women, who were administered the experimental task. Following a simulation design, all participants performed under control and faking conditions. Their accuracy of performance and response times were measured. Analysis indicated significant differences on both outcome measures for the two conditions. Further, a significant difference in accuracy, but not in response time, among levels of task difficulty was observed. For classification accuracy, using the cut-off score criterion seemed more effective than using the below-chance criterion or response time. Implications for relying on chance criterion to identify deception are discussed.

This study analyzed the demographic characteristics and psychiatric diagnoses of 90 consecutive patients who visited a sleep disorder clinic in Taiwan with complaints of insomnia (difficulty initiating or maintaining sleep, or nonrestorative sleep) or hypersomnia (excessive sleepiness as evidenced by either prolonged sleep episodes or daytime sleep episodes that occur almost daily). All subjects were interviewed using a sleep disturbance questionnaire and the structured Mini-International Neuropsychiatric Interview supplemented by the DSM-IV criteria for psychiatric diagnoses. Among 90 patients, 79 were classified as having insomnia and 11 had hypersomnia. 53 patients also had psychiatric diagnoses other than sleep disorders. Patients with insomnia had a significantly higher rate of comorbidities with other psychiatric diagnoses (65.8%) than did subjects with hypersomnia (9.1%). These results emphasize the importance of psychiatric evaluation of patients with complaints of sleep disturbance.

As part of an ongoing investigation, data were collected on behaviors and attitudes about substance abuse and general knowledge about substances for high school students (N = 1,103) during the 2002–2003 and 2003–2004 academic years. In preliminary analyses no meaningful sex differences were found for type or frequency of use, attitudes about substance use, or knowledge about substances. Lack of meaningful sex differences were evident even when comparisons by sex group were made within this ethnic minority population as well as within school Grades 10, 11, and 12. It is suggested that being a boy or a girl may have little to do with the American middle-class adolescents' choice to use substances. Findings should be understood to suggest possible cohort effects.

The reliabilities of Helms' People of Color Racial Identity Attitude Scale and White Racial Identity Attitude Scale when used with a sample of master's counseling students were explored for modified versions. Reliabilities were assessed using Cronbach alpha as a measure of internal consistency, and temporal stabilities were measured. Results were consistent with previous findings, with coefficients alpha ranging from .67 to .77 for the modified People of Color Racial Identity Attitude Scale, and from .36 to .84 for the modified White Racial Identity Attitude Scale. Analyses also identified items that may suppress internal consistencies in responding by this sample.

Buying and selling items on eBay was predicted in a sample of 386 undergraduate students from two institutions by computer or Internet skills, year and, for buying items on eBay, sex.

As some authors have noticed in fields other than psychology, level of measurement and distributional characteristics of count data are commonly not taken into account, so that they are analysed as normally distributed continuous variables, and therefore some general linear model is applied. In this work, we review a random sample of 457 articles published in the last four years in journals with the highest impact factor in the Journal Citation Reports (JCR Social Sciences Edition) of the Institute for Scientific Information. The goals are to know how often count variables appear in psychological applied research and which data analyses are used when dealing with count response variables. Examination showed that there is a notable presence of count variables, especially in some topics in psychology and a remarkable misapplication of the general linear model. One deals with causes and consequences of this approach to data analysis and suggests the use of specific models to analyse count data.

The 1996 Beck Depression Inventory-II was administered to 120 outpatients diagnosed with DSM-IV-TR bipolar I disorders who had recently experienced manic, mixed, or depressed episodes. A focused contrast supported the hypothesis that the mean Beck-II total score for the 40 patients with depressed episodes (M = 34.1, SD = 13.2) was higher than the mean Beck-II total score for the 40 patients with mixed episodes (M = 25.9, SD = 13.6) which was, in turn, higher than the mean Beck-II total score for the 40 patients with manic episodes (M = 11.7, SD = 7.8, p <.001). The Beck Depression Inventory-II appears to be useful for measuring self-reported depression in patients with bipolar I disorders.

A sample of 528 successive admissions to the Phoenix Program, a voluntary inpatient treatment program for sex offenders, was studied in regards to serum prolactin levels. Serum prolactins were obtained as part of a battery of endocrine tests. A substantial number of patients had prolactin levels above the normal range, i.e., 21.0 μg/L. In this sample, fully 10.0% of the men showed elevated prolactin levels (the maximum being 41.0 μg/L), compared with an expected 2.5% according to laboratory norms. None of these individuals had clinical manifestations of prolactinoma. The significance of this increased rate of hyperprolactinemia in this sample of sexual offenders is unclear. There was a negative correlation with age and no correlation with other endocrine tests.

This study assessed differences in response rates to a mailed health survey by adults in two neighboring rural midwestern counties with differential incentives, of $2.00 and $5.00. Potential respondents in each county were randomly selected from a commercial database of residents' addresses. County “F” respondents (n = 541) which were 57% female and 95% Euro-American having a mean age of 47.3 yr. (SD = 16.9), received the $5 incentive. County “H” respondents (n = 514) were 63% female, 95% Euro-American, had a mean age of 49.0 yr. (SD = 14.7), and received a $2 incentive. The response rates were 71% using the $2 incentive and 73% using the $5 incentive. These were not significantly different by chi-square test. The more cost-effective incentive for increasing the response rate of adults in this rural midwestern sample was to code the envelopes and use a $2.00 rather than $5.00 incentive, a cost per returned survey of $5.24 versus $9.13, respectively. The findings support Dillman's principle of diminishing returns as the size of the incentive goes up.

59 art collectors (30 men, 29 women) were given the Gregorc Style Delineator to classify them by thinking styles and a questionnaire regarding their art preferences. Their ages ranged from 33 to 99 years (M = 59.5 yr.). Abstract art was preferred by 34% of the sample. Representational art, such as Dutch Masters and Impressionism, was preferred by 66% of the sample. Of the collectors who preferred nonobjective abstract paintings, such as works by color field artists like Mark Rothko, and Abstract Expressionist paintings, such as works by Jackson Pollock, 62% had scores on the Gregorc Style Delineator by which they were classified as showing abstract thinking styles. Of the collectors who preferred representational painting, 86% were classified as showing concrete thinking styles.

Moriguchi and Itakura (2005) compared 3-yr.-old children's performance on the standard version of the Dimensional Change Card Sort with performance on a new, No Conflict version. Here, it is noted that the children's successful performance on the No Conflict version is consistent with existing theoretical interpretations of children's performance on the standard version.

This study investigated the relationship between scores of college students (N = 210, 114 women, 95 men, 1 unidentified; M age = 19.3 yr., SD = 2.8) on Machiavellianism and their motives for communicating with their instructors in the classroom. Students' Machiavellianism scores were positively but weakly related to three motives of Functional (r = .22, p <.01), Excuse-making (r = .16, p <.05), and Sycophancy (r = .17, p <.05).

A permutation method is presented to calculate resampling probability values for differences between two independent indices of ordinal variation and consensus.

The MMPI-2 Restructured Clinical scales rest on the common behavioral assumption that consistent items can be added to assess all psychopathologies. This may be the case for some unitary symptoms such as anxiety or anger, but not for complex diagnostic conditions such as Hysteria, Post Traumatic Stress Disorder, and Borderline Personality Disorder. These are better understood with a psychodynamic formulation. Psychodynamic theory assumes that internal conflicts and contradictions are a significant feature of many psychopathologies. For example, the new MMPI-2 Restructured Clinical scales eliminated a measure of hysteria. The RC3 Cynicism scale is not an improvement over the MMPI-2 Hysteria scale, as the new scale serves as an example of a failure of the behaviorism to account for complex psychopathology. Making scales more internally consistent and distinct from each other has not produced more external validity and useful measures for many of the psychopathologies found in clinical practice.

The data obtained with two forms of the Impact of Event Scale were compared, one referring to a BRCA1/2 test result (IES-T) and another to cancer (IES-C). The sample consisted of 272 women with a family history suggestive of a BRCA1/2 mutation who underwent genetic testing and received results: noncarrier, carrier, or inconclusive. Globally, mean scores on the IES-C form were higher than those obtained on the IES-T form. Among carriers of a BRCA1/2 mutation, mean scores on the two forms were similar and agreement was good, as measured by the in-traclass correlation coefficient (.83; 95% 95% CI = .72, .91). Agreement between the forms was poor to fair among noncarriers (ICC = .38; CI = .15, .57) and women with an inconclusive result (ICC = .40; 95% CI = .26, 52). Having had cancer increased total scores but had little influence on agreement between scores on forms. These findings highlight the importance of carefully selecting the form of the Impact of Event Scale in the context of genetic testing for breast cancer susceptibility.

This study estimated the relationship between followers' locus of control and organizational citizenship behaviors for a sample of 375 government employees, whose M age was 46 yr. 53% were women; 42% earned bachelor's degrees. Analyses showed a significant positive correlation of .35 between followers' locus of control and their organizational behaviors. More complex models and research designs are necessary to generalize.

In a procedure similar to that used in Asch's classic studies in 1946, 125 college students (54 men and 71 women, M age = 20.9 yr., SD =4.8) rated their impression of a hypothetical man or woman who was described by seven stimulus traits. This list included one of four central traits which appeared in the middle of the list: warm, cold, serious, or foolish. The dependent measures were factor scores derived from participants' ratings of 20 traits on social desirability and intellectual desirability. As hypothesized, warm and cold, prototypes of social desirability and undesirability, were associated with judgments of social but not intellectual desirability, and serious and foolish, prototypes of intellectual desirability and undesirability, were associated with judgments of intellectual but not social desirability. In addition, there was evidence of a subtle sex bias: ratings of “foolish” women were higher on social desirability than ratings of “foolish” men.

Researchers have suggested there may be sex differences in attitudes towards credit card possession and use. Undergraduates, 41 men and 41 women, completed a survey regarding their attitudes towards credit, credit card use, and repayment. Analysis indicated sex played a significant moderating role between number of credit cards used and the importance of paying off monthly balances. Women possessed more credit cards than men and engaged in more frequent shopping. Number of credit cards increased with paying off of monthly balances. Data are discussed in terms of the importance of managing credit card debt in an increasingly cashless society.

This study examined the roles of metacognitive experiences in the self-regulation process before problem-solving. 260 Japanese undergraduate students participated. To investigate the role of metacognitive experiences, a structural equation model was constructed to examine the relations among Self-efficacy, Goal Setting, Metacognitive Experiences, and Performance. Analysis showed that Metacognitive Experiences mediated the influence of Self-efficacy on Goal Setting and Performance. In addition, these experiences were related to Performance to some extent. Finally, these results are discussed in relation to those obtained in previous studies.

This paper clears up some misunderstandings of Woodard's Phenomenological and Perceptual Research Methodology presented by Beshai in a recent critique. Beshai's critique helps demonstrate and validate a number of themes in Woodard's Perceptually Oriented Hypnosis. First, for each of us, our historical learnings provide the basis for scientific progress but at the same time may impede new views and even a more comprehensive understanding of hypnosis. Second, hypnosis is fundamentally a process of differentiating personal meanings that can be vastly different for various individuals. Third, Beshai uses a quantitatively based approach to understanding phenomenon different from Woodard's qualitative research process. Last, holistic understanding of hypnosis is impeded when aspects of the phenomenal field are taken quantitatively out of context.

The Gregorc Style Delineator was administered to 26 full-time, professional engineers, all women. Participants preferred concrete thinking styles. This tendency is similar to scores on other measures in much larger samples of engineers for whom sex was not specified.

Sageman's (2004) and Pape's (2005) arguments for the development of Al'Qaeda members and suicide terrorism are examined statistically. Presence of foreign occupying troops and foreign support for disliked local regimes appeared to be related to either the number of Al'Qaeda suicide terrorists (Pape) or the number of known Al'Qaeda members (Sageman) reported within 34 predominately Sunni nations. Results support the theory that nationalism fuels much of Middle Eastern resentment against allied nations.

The present study supplemented the limited 1999 psychometric data by Lewis, et al. on the Czech translation of the Satisfaction With Life Scale by examining the temporal stability of the measure over a 1-wk. period for 64 Czech undergraduate university students. Analysis indicated stability across the two administrations was very high (r = .90), and there was no significant change between Time 1 (M = 23.7, SD = 5.1) and Time 2 (M = 24.1, SD = 5.5). Short-term test-retest reliability of this Czech translation is supported.

The Kuwait University Anxiety Scale was administered to 138 American college students and three meaningful factors identified, somewhat different from those identified by Abdel-Khalek in 2000.

The association of political attitudes of conservatives and reports of their having had a dream was investigated. 48 female graduate students in counseling psychology were given the KJP Dream Inventory and the Kerlinger Social Attitude Scale II. Scores on conservative political attitudes were positively correlated with having had Dreams of Falling (.40), Dream Discontentedness (.31), Dreams of Being Chased (.40), and Dreams of Being Famous (.30). Negative correlations were observed between scores showing a conservative political tendency and scores on Openness (−.35), and Uninhibitedness (−.50), as well as incidence of Dreams of Sex (−.29). The character of conservative dreaming is discussed along with the study's relevance to past and subsequent issues in research.

Currently, individuals tend to encounter many unavoidable, painful events and hardships in the process of growth and development. To lead one's life adapting to these social conditions, it is necessary to maintain one's mental health even while experiencing challenging events; in other words, resilience is required. This study of 130 undergraduates focused on the Adolescent Resilience Scale which assesses capacity for successful adaptation despite challenging or threatening circumstances and examined correlations with scores on the Big Five Personality Inventory. A significant negative correlation of –.59 (p <.001) was noted for scores on the Adolescent Resilience Scale and the Neuroticism dimension of the Big Five Personality Inventory, accounting for 35% of the variance, and positive values with the Extraversion, Openness, and Conscientiousness dimensions (rs = .37, .40, .48, accounting for 14, 16, and 18% of the variance, respectively. Personalities of adolescents who have psychological traits leading to resilience may be partially predicted using these results.
