MICHAEL R. LIEPMAN M.D. TED D. NIRENBERG Ph.D. RICHARD H. DOOLITTLE M.S.W. Ed.D. ANN M. BEGIN M.A THOMAS E. BROFFMAN M.S.W. L.I.C.S.W. MARK E. BABICH M.A. 《Family process》1989,28(2):239-249
Family functioning of 20 alcoholic male veterans and their female partners was assessed in relation to drinking (wet) and abstinent (dry) intervals. Repeated measures analyses performed on the McMaster Family Assessment Device (FAD) indicated that on all 7 scales of the FAD, alcoholics and their mates perceived family functioning to be better during dry than wet periods. In contrast to their alcoholic mates, female partners gave healthier ratings to all FAD scales except Roles in the dry condition and Affective Involvement in the wet condition. According to published cutoff scores for healthy and unhealthy family functioning, alcoholics as a group viewed their wet and dry family functioning as unhealthy, although the female group regarded the family's dry Problem Solving and Behavioral Control as healthy. These findings suggest that the family functioning of alcohol-involved couples is biphasic, oscillating between drinking and abstinent periods. 相似文献

Enuresis was investigated in the context of different styles of training for bladder control among three Israeli ethnic groups (Jews of Moroccan, Kurdish or Eastern European descent). Semistructured interviews were conducted in ethnically homogeneous agricultural villages with 46 mothers of 248 children between the ages of 3 and 18 years. In contrast to previous British and American studies, no sex differences were found, but there were higher rates of primary enuresis and lower rates of secondary (regressive) enuresis. Enuresis was correlated among siblings in the Kurdish group only and with disorderly sleeping arrangements in the Moroccan group. The Moroccan and Kurdish groups had higher rates of enuresis than the Ashkenazi group. The higher rates appear to be related to differences in the age of onset of training and a lack of age-appropriate changes in the parent-child interaction, which led to chronic enuresis and the inability to seek effective assistance. These results are discussed in terms of a proposed typology for training: an early symbiotic style, a strict toddler style, and a communicative partnership. 相似文献

It has generally been assumed that increases in the concrete outcomes of a procedure will result in judgments of greater procedural and distributive fairness, but research on this topic has been inconsistent. Using a classic procedural justice paradigm (Walker, LaTour, Lind, &. Thibaut, 1974), the experiment tested the effects of four levels of outcome. Forty-eight male and female undergraduates were led to believe that their team had been wrongfully charged with cheating in a business simulation game. An adversary adjudication was held, purportedly to resolve the charge. The outcome of the adjudication was confiscation of all, two thirds, one third, or none of the subject's monetary winnings from the game. Both procedural and distributive fairness measures showed dear nonlinear outcome effects. The relationship between outcomes and both fairness measures showed some evidence of being nonmonotonic as well: A two-thirds loss resulted in less favorable reactions than did a total loss. Ratings on other scales suggest that the nonlinear effects are due to beliefs that the judge did not fully consider the evidence in the two-thirds loss and one-third loss conditions. The discussion focuses on the theoretical implications of the findings for procedural justice and social exchange processes and the practical implications for conflict resolution procedure. 相似文献

This paper demonstrates a method of transferring research data from a remote clinic to a large university mainframe for data manipulation and statistical analysis. Data collected by an Apple //e computer were transferred to an IBM 3031 mainframe by sending data files to an IBM PC by telephone modem or by direct hardwire connection to the PC. The IMB PC performed data-formatting routines and then uploaded the files to the mainframe for storage. Advantages and disadvantages of sending data over telephone lines via a modem are discussed. 相似文献

Single-subject statistics were used to analyze physiological data [electromyographic (EMG) temperature] recorded from two patients receiving computer-assisted biofeedback treatment in a clinic. When the data were analyzed by an ANOVA method or a regression technique, the results demonstrated that both patients learned to significantly reduce EMG levels. The rationale of using single-subject statistics is discussed, and the applicability of the statistical technique to the clinic population is illustrated. 相似文献

Determination of a behavioral transfer function: White-noise analysis of session-to-session response-ratio dynamics on concurrent VI VI schedules 总被引:10,自引:10,他引:0 下载免费PDF全文
Six pigeons were exposed to concurrent variable-interval schedules in which the programmed reinforcer ratios changed from session to session according to a pseudorandom binary sequence. This procedure corresponded to the stochastic identification paradigm (“white-noise experiment”) of systems theory and enabled the relation between log response ratios in the current session and log reinforcer ratios in all previous sessions to be determined. Such dynamic relations are called linear transfer functions. Both nonparametric and parametric representations of these, in the form of “impulse-response functions,” were determined for each bird. The session-to-session response ratios resulting from the session-to-session pseudorandom binary variations in reinforcer ratios were well predicted by the impulse-response functions identified for each pigeon. The impulse-response functions were well fitted by a second-order dynamic model involving only two parameters: a time constant and a gain. The mean time constant was 0.67 sessions, implying that the effects of abrupt changes in log reinforcer ratios should be 96% complete within about five sessions. The mean gain was 0.53, which was surprisingly low inasmuch as it should equal the sensitivity to reinforcement ratio observed under steady-state conditions. The same six pigeons were subjected to a similar experiment 10 months following the first. Despite individual differences in impulse-response functions between birds within each experiment, the impulse-response functions determined from the two experiments were essentially the same. 相似文献
