A computer interview was developed to collect information about drug use/abuse from high school students. Responses to this interview were compared with those obtained from an identical paper-and-pencil questionnaire given to the same students, in counterbalanced order. Results were comparable for the two methods, but missing data and logically inconsistent answers obtained with the paper-and-pencil questionnaire were not possible with the computer interview. The overwhelming majority of respondents preferred the computer interview as a means of data collection. 相似文献

A sample of 384 husbands and wives were randomly selected and interviewed to investigate the implication of fertility norms and motivations for childbearing on fertility and family planning behavior among Iranian families in urban and rural areas of Iran, after the Islamic Revolution of 1979. The term "fertility behavior" refers to actual family size, which is defined as number of children the respondent has living at the time of the interview. "Family planning behavior" refers to the duration of time that the subject has used any birth control method(s). Rural families demonstrated larger actual and ideal family sizes than urban families. The rural sample had a median actual family size of 3.5 children and a median ideal family size of 4.7 children. For the urban sample these figures were 2.2 and 2.3, respectively. The median number of years married was 12.33 for rural and 13.91 for urban respondents. Urban respondents tended to emphasize the psychological and emotional benefits and liabilities associated with having children while rural respondents tended to emphasize both economic and security related motivations. Both groups endorsed infant mortality as a motivation for having more children. Male and female respondents were remarkably similar in their endorsed motivations. There was a significant positive correlation between desired and ideal family size. The correlations among ideal/desired family size and practicing birth control methods were the same and significant at the .001 level. The relationship between motivations for childbearing and years of practicing birth control methods was also significant at the .001 level. Stepwise regression analyses were performed to examine the important predictors of fertility and family planning behavior. For both actual family size and years on birth control, males and females were very similar in terms of predictor importance. Those respondents with less education and large ideal family size tended to have larger actual family size. Location (urban/rural) and parents, family size was weighted much more heavily for males than for females. Those respondents with greater education and who lived in an urban areas tended to have used birth control for longer periods of time. Ideal family size did not contribute significantly to this regression. Parents' family size and motivations for childbearing made marginal contributions to regressions on either dependent variable. 相似文献

We provide evidence that the capacity of young children to engage in social interaction exceeds that suggested by Piaget (1926). Rather than being collective monologues, the conversations between the subjects of this study (twin boys) were dialogues: the children attended to one another's utterances and provided relevant responses. This was observed for conversations which were referentially based as well as for sound play exchanges. This is not to say that the children experienced no difficulty in sustaining cooperative discourse. It could take a speaker several turns to secure the attention of the coconversationalist and establish a discourse topic. 相似文献

Two experiments investigated free-operant avoidance responding with pigeons using a treadle-pressing response. In Experiment I, pigeons were initially trained on a free-operant avoidance schedule with a response-shock interval of 32 sec and a shock-shock interval of 10 sec, and were subsequently exposed to 10 values of the response-shock parameter ranging from 2.5 to 150 sec. The functions relating response rate to response-shock interval were similar to the ones reported by Sidman in his 1953 studies employing rats, and were independent of the order of presentation of the response-shock values. Shock rates decreased as response-shock duration increased. In Experiment II, a free-operant avoidance schedule with a response-shock interval of 20 sec and a shock-shock interval of 5 sec was used, and shock intensities were varied over five values ranging from 2 to 32 mA. Response rates increased markedly as shock intensity increased from 2 to 8 mA, but rates changed little with further increases in shock intensity. Shock rates decreased as intensity increased from 2 to 8 mA, and showed little change as intensity increased from 8 to 32 mA. 相似文献

Three studies were conducted to evaluate the influence of environmental context and UCS preexposure intensity on the acquisition of a flavor aversion. In the first study, rats were exposed to two UCS-alone presentations at one of three dose levels of LiCl. The rats were given the two UCS preexposures in one of two contexts (familiar or novel). Following the UCS-alone treatment, all of the subjects received two pairings of sucrose and LiCl (1.25 meq) in the familiar context. Animals receiving UCS preexposures in the same context as used during conditioning consumed significantly more sucrose than did saline control animals. In contrast, the influence of prior UCS preexposure was not evident when UCS preexposure was experienced in a context different from that experienced during conditioning. In Experiment 2, all animal received UCS preexposure and conditioning in the novel room. Animals received either two or four preexposures at 0, 1.25, or 3.75 meq dose of LiCl. Two UCS preexposures at 3.75 meq dose produced a stronger UCS preexposure effect than did the 1.25 meq dose. Animals in Experiment 3 received two exposures to either 0-, 1.25-, or 3.75-meq LiCl in one of two contexts, followed by conditioning with the 1.25-meq LiCl dose in the same context as preexposure. Greater UCS interference occurred in animals preexposed to LiCl in the novel rather than familiar environment, with no specific dose effects in either context. These observations are discussed in terms of context blocking and generalization decrement models of the UCS preexposure effect. 相似文献

This study examined the preferred professional treatment approach at a residential treatment center for socially and emotionally maladjusted girls. The dorm child-care workers and the clinical and educational staff responded to a questionnaire composed of statements reflective of three theoretical orientations: psychoanalytic, person-centered, and cognitive-behavioral therapy. No significant differences were found between the three departments (clinical, school, dorm) for each model of therapy. The results also indicated that the professional personnel employed at this treatment facility were all in agreement that the cognitive-behavioral model of therapeutic intervention is the one preferred. Implications of these findings are discussed. 相似文献

WORDS is a computer-oriented system for content analysis designed to elicit major content themes without recourse to a priori categorization systems. The system consists of a number of modular and independent programs that the user can configure in any fashion to process the data to be analyzed. This paper presents current information on WORDS, WORDS programs, WORDS systems logic, and on the availability of the system. 相似文献

The present research examined marital therapy outcome, in a sample of 88 couples and 22 therapists, through the use of multidimensional criteria from multiple perspectives. Three paper-and-pencil patient self-report instruments were used to measure different aspects of the couple relationship. In addition, therapist post-therapy ratings and objective observer ratings of the couple behavior during therapy were obtained. Past debates about what the "right" criteria might be for measuring therapeutic change prompted our strategy. Special attention was focused on those criteria that could be classified as "inside" or "outside" of the couple relationship. Data analysis revealed a significant relationship between the couples' and therapists' ratings of improvement in therapy. Additionally, husband and wife negative acts (behaviors) in therapy were also significantly correlated with therapists' ratings of improvement. Both statistically significant and clinically significant criteria were employed to evaluate the therapy outcome. Improvement due to therapy as measured by the three self-report instruments varied from 38% to 58%. These differences appeared to stem from the different kinds of information yielded by the specific tests. 相似文献
