The impact of pre-employment integrity testing on employee turnover and inventory shrinkage losses 总被引:1,自引:0,他引:1

A major home improvement chain located primarily in the western United States initiated the use of thePersonnel Selection Inventory, a written integrity test, as part of its pre-employment hiring process. For two years only, those job applicants who passed this test and other pre-employment criteria were hired by the chain. Following the introduction of the inventory, there was: (1) a 50% reduction in the number of employee terminations for theft, illegal drug use, and violence over a five year period and (2) a savings in shrinkage losses that amounted to over two million dollars over a two year period. 相似文献

Clinical staff’s attributions about diabetes management were measured using newly developed scales. Eighty-five physicians
and nurses provided data to investigate the psychometric properties of the scales and to examine the patterns of attributions
made. Alpha coefficients for the 7 six-item scales were satisfactory, ranging from .51 to .73. A comparison between attributions
for positive and negative outcomes of diabetes management produced examples of self-serving bias. Comparisons were made with
data from 286 insulin-dependent diabetes patients. Staff tended to rate patients as having less personal control over positive
outcomes (t=2.94;df=338;p<.01) and tended to emphasize chance to a greater extent than did the patients (t=−4.32;df=338;p<.001). There was a tendency for staff to rate negative outcomes as being more foreseeable by the patients than the patients
did themselves (t=−3.11;df=346;p<.01). Both patients and staff demonstrated bias towards dispositional attributions. The implications of between and within
group differences in attribution patterns are discussed.

A social skills training program was evaluated with emotionally disturbed adolescent inpatients. The targeted social skills required an action or reaction within six skill areas. The program was adapted from a commercially available social skills training game that features the use of response specific feedback, self-monitoring, individualized reinforcers, and individualized performance criteria. A peer conducted the baseline and posttraining sessions while the training was conducted by an adult who had no previous interactive history with the subjects. A multiple baseline design across groups demonstrated that the program increased appropriate responding in all skill areas and that these effects generalized during the posttraining peer conducted sessions. A generalization test indicated that the subjects used their newly learned skills with a novel adult outside the training setting. The program appears quite applicable to emotionally disturbed adolescents since it targets skills in a variety of areas and employs standardized procedures to enhance replicability. 相似文献

Among a sample of American college students, body image and the degree of desired weight change were associated with academic self-rankings, with social and psychological well-being, and with the development of eating difficulties. The effects of body image and desired weight change on eating disorders were generally found to be greater for women than for men, and their effects on student self-rankings of academic ability, social, and psychological traits were more pervasive for women than for men. The less attractive a woman perceived herself to be and the more weight she wanted to lose, the greater was her overall sense of academic, social, and psychological impairment. Women who had poor body images and who desired to lose weight were more likely to report eating difficulties. 相似文献

A one-semester course in statistics and research design is described. All computations are carried out by a Macintosh computer. No hand calculation is expected of the students, and little class time is spent on computational procedure. The course covers much more statistical content than is the norm for a one-semester course, and student understanding of the logic of the material and its application is enhanced. 相似文献

A rationale for a simple method for determining the inter-relatedness of two discrete fears was developed and subjected to experimental test. A system for making such distinctions proved to be satisfactory, but we found no relationship between the person's own estimation of the similarity of the two fears and the index of independence that was derived experimentally. Possible uses of the method are suggested. 相似文献

The purpose of this study was to ascertain which sex education topics parents of preadolescents regarded as appropriate for their children. The sample was comprised of 146 respondents randomly selected from a class list of sixth graders in a suburban school district. A mailed, self-administered questionnaire listing 48 possible topics was used to elicit parental response. Pretesting found the questionnaire to be highly reliable (Cronbach's alpha = .95). Overall, parents strongly supported the inclusion of a broad range of sex education topics regardless of parental age, sex, marital status, income, education, or child's sex. Moreover, parents were largely in agreement with the inclusion of sensitive topics in addition to those which were more physiological or behavioral. Catholics more often than Protestants agreed with the inclusion of birth control, abortion, and sterilization even after controlling for income and education. Thus, the findings suggest that parents of sixth graders find a broad sex education program in the school appropriate. To this end, school officials and sex educators should not overlook the needs of preadolescents for sex education solely on the basis of perceived parental opposition. 相似文献

The purpose of this study is to examine the interrelationships among coping statements, a self-report measure of anxiety and maladaptive overt behavior in a real-life stressful situation. Measures of these variables (interviews using TAT-like cards, State-Trait Anxiety Inventory for Children, Behavior Profile Rating Scale) were taken from 23 adolescents prior to and during their dental visit. Results indicated that as disruptive "in-chair" overt behavior increased, so did the percentage of coping statements. In addition, as self-report levels of anxiety increased, the percentage of coping statements significantly decreased. Interestingly, there was no significant relationship between self-report levels of anxiety and disruptive in-chair behavior. It was also noted that the subjects' self-report levels of anxiety significantly decreased following their opportunity to verbalize their coping/noncoping statements via the TAT-like procedure. The implications of these interrelationships to cognitive-behavioral theory are discussed. 相似文献

This study measured students' attitudes toward a university's student health services (SHS) and identified factors that were related to their attitudes. A questionnaire surveying students' attitudes was administered to a sample of 150 students at the Oxford Campus of the University of Mississippi. Analysis of the data revealed that students' attitudes had a statistically significant correlation with the following variables: perceived medical care cost, amount of health information/education received during medical encounters, time spent in the waiting room of the SHS, sex of the student, and income of the student. There was no significant relationship between attitude and age. 相似文献

Physiognomic color responses in perception, imagery, and affect were investigated. Maluma and taketa, nonsense stimuli defined by many investigators as physiognomic, were utilized as prototypical physiognomic stimuli, along with eight other stimuli of various sorts. In Experiment 1, 22 subjects matched the colors of the stimuli; in Experiment 2, 27 subjects reported their imagery to the stimuli; and in Experiment 3, 16 subjects gave their color preferences for the stimuli. The Munsell sets of colors were employed throughout. Significant differences between the physiognomic and other stimuli were found on the brightness and saturation of color matches, images, and preferences. Other differences (e.g., the latency of color images) were also present. Distinctions were also noted between the two physiognomic stimuli. These results support the priority of innate and perceptual processes in physiognomy over those of learning and memory, although some ambiguities still remain. 相似文献
