This study tested whether quantity and quality of social support and two sources of work stress (organizational stressors and job risk) predicted work strain in police officers, a high-risk occupational group. The participants were 135 police officers from a large metropolitan law enforcement agency who responded to questionnaires for assessing work stress, social support, exhaustion, and other strain symptoms. Emotional support and work stressors accounted directly for significant variance in emotional exhaustion, depersonalization, and symptom frequency. Conflicted relationships, which are a source of both work stress and support, also contributed to strain. In contrast to previous findings, a reverse buffering effect for social support did not contribute to predicting strain. Stress management programs for police and other high-stress occupations should target increasing emotional support from supervisors and peers, and reducing conflict in job and family relationships. 相似文献

Recent studies pertaining to an extended class of matched pairs tests based on powers of ranks are discussed. Previous questions regarding the asymptotic properties for this class of tests are clarified and a generalization of this class is described. This generalization raises a previously unanticipated concern about whether or not the analytic comparisons resulting from these tests correspond with an intuitive notion of what is being compared. 相似文献

A comparison of the effects of posted feedback and increased police surveillance on highway speeding
A counterbalanced, reversal design was used to compare the effectiveness of posted feedback and increased police surveillance in reducing speeding on two urban highways. Drivers' speeds were measured using a concealed radar unit. During public posting, a large highway sign, which listed the percentage of drivers not speeding during the preceding week and the best record to date, was erected on each street. Use of the feedback sign alternated with periods of baseline and periods of increased police surveillance and ticketing. During increased police surveillance, highly visible, stationary police radar patrols were established along the highways for either 30 min or 60 min per day, 5 days per week. Results indicated that although public posting was highly effective in reducing the percentage of speeding drivers, increased police surveillance was not. Thus, since the feedback sign required only 30 min per week to maintain, public posting was at least 10 times more efficient in controlling speeding than was police surveillance and ticketing. 相似文献

Seventy convicted young male offenders were videotaped during a 5-min standardized interview with a previously unknown adult. In order to determine the social validity of the behavioral components of social interaction for this population, measures of 13 behaviors were obtained from the tapes. These measures were then correlated with ratings of friendliness, social anxiety, social skills performance, and employability made by four independent adult judges from the same tapes. It was found that measures of eye contact and verbal initiations were correlated significantly with all four criterion rating scales. The frequencies of smiling and speech dysfluencies were both significantly correlated with ratings of friendliness and employability. The amount spoken was found to be a significant predictor of social skills performance whereas the frequency of head movements influenced judgments of social anxiety. The latency of response was negatively correlated with social skills and employability ratings and the frequency of question-asking and interruptions correlated significantly with friendliness, social skills, and employability ratings. Finally, the levels of gestures, gross body movements, and attention feedback responses were not found to influence judgments on any of the criterion scales. The implications of the study for selection of targets for social skills training for adolescent male offenders are discussed. 相似文献

We examined the effects of simulation training on performance of clean intermittent self-catheterization procedures with 2 young girls. Simulation training was conducted, after which independent performance was assessed within a multiple baseline design. The training resulted in increased accuracy and decreased latency for both girls. 相似文献

Interobserver agreement (also referred to here as "reliability") is influenced by diverse sources of artifact, bias, and complexity of the assessment procedures. The literature on reliability assessment frequently has focused on the different methods of computing reliability and the circumstances under which these methods are appropriate. Yet, the credence accorded estimates of interobserver agreement, computed by any method, presupposes eliminating sources of bias that can spuriously affect agreement. The present paper reviews evidence pertaining to various sources of artifact and bias, as well as characteristics of assessment that influence interpretation of interobserver agreement. These include reactivity of reliability assessment, observer drift, complexity of response codes and behavioral observations, observer expectancies and feedback, and others. Recommendations are provided for eliminating or minimizing the influence of these factors from interobserver agreement. 相似文献

Two eight-member equivalence classes of visual stimuli were established during three phases of a training program. In Phase 1, two training arrangements were compared. In one, 3 subjects were taught on different trials to select from a single pair of comparison stimuli (A1, A2) in response to eight sample stimuli that were trained in pairs (B1, B2; C1, C2; D1, D2; E1, E2). In the second arrangement, subjects were taught to select from four pairs of comparisons (B1, B2; C1, C2; D3, D2; E2, E2) in response to two samples (A1, A2). Training with the single pair of comparison stimuli resulted in the development of equivalence relations (B1C1, B2C2, D1B1, D2B2, B1E1, B2E2, C1D1, C2D2, C1E1, C2E2, D1E1, D2E2, and their reciprocals) between the sample stimuli without direct training of these relations. In the other training arrangement, these relations among the comparison stimuli developed in the performance of 1 subject only. In Phase 2, three new pairs of stimuli (F1, F2; G1, G2; H1, H2) were substituted for three of the original pairs (B1, B2; C1, C2; D1, D2) and the training arrangements for the groups were reversed. Following training, the performances that showed equivalence relations on the probes in the first phase also showed equivalence relations in the second phase. If such relations did not develop in the first phase, they did not do so in the second phase. In Phase 3, relations between stimuli across the two previous phases (e.g., B1F1, B2F2, B1G1, B2H2, C1F1, etc.) were investigated. The 4 subjects whose performances showed the development of these relations were taught to select one stimulus from each class (E1 and E2) in response to a verbal label (I1 and I2) and then were tested to see if the verbal label controlled responding to the remaining members of the class (e.g., I1A1, I2A2, I1B1, I2B2, etc.). For 3 subjects, this generalized control occurred; for the 4th, generalization occurred only after verbal training with a second pair of visual stimuli (F1 and F2). In retests several months later, these auditory-visual relations were found to be intact or, if not, were recovered without direct training. 相似文献

The residential burglary deterrent effects of a helicopter patrol procedure were investigated in four separate areas with a multiple baseline technology. The helicopter was flown during an 8:00 a.m. to 4:00 p.m. period in two high density population areas of approximately 9.82 and 14.71 square miles and two low density population areas of 117.49 and 89.97 square miles. The helicopter patrol reduced residential burglaries without crime displacement in the two high density areas but had no deterrent effects in the low density areas. The costs of the helicopter patrol were justified by the benefits that resulted from the reduced home burglaries in the two high density areas. Because the helicopter patrol program is funded by general tax revenues, there is a disparity between those people paying for the procedure (all residents of Nashville) and those citizens that receive the burglary deterrent benefits (only residents of high-density areas). This distribution of benefit limitation suggests two courses of action: (1) The helicopter should be flown only in high population density areas even though the low population density areas are also victimized by high burglary rates. (2) A more comprehensive burglary reduction program must be developed so that effective deterrence can be realized in low density areas. These latter techniques would supplement helicopter patrol strategies and thus form a comprehensive burglary deterrent package that has an equitable benefit distribution. 相似文献
