摘要:

Discussions in the nursing literature about the usefulness of Kohlberg's theory of moral reasoning for women and nurses, and assertions about the level of moral reasoning scores of nurses have been clouded by inaccuracies and misperceptions. In this article, theoretical and measurement issues related to moral reasoning are clarified and a critical review of the literature is provided about the moral reasoning of nursing students and nurses as measured by the Defining Issues Test (DIT). The review indicates the need for greater rigor in studies of moral reasoning among nurses and the need for accuracy in interpreting and reporting moral reasoning scores. The data show that the moral reasoning of nurses, like that of other groups, tends to increase with formal education. Nurses' scores are usually comparable to, and sometimes higher than, scores of their academic peers.

摘要:

The purposes of this study were to factor analyze the 25-item Personal Resource Questionnaire (PRQ) 85-Part II, a social support measure, and to establish construct validity for the instrument among adolescents by testing two hypotheses derived from theoretical propositions by Weiss (1974) concerning the relational provisions of social support. The purposes were accomplished using a sample of 325 adolescents, aged 12 to 21. According to the criteria used in this study, a four-factor structure, resulting from a principal components analysis with an oblique rotation, best represented the multidimensionality of the PRQ85-Part II in adolescents. A second-order factor analysis indicated that the four first-order factors correlated to form one factor, which consisted of 17 items and was labeled Perceived Social Support. Evidence in support of construct validity for both the 17-item and 25-item PRQ85-Part II was provided by statistically significant correlations found between the two scales and the theoretically relevant variables of perceived health status and symptom patterns. The contributions of this study to the psychometric properties of the PRQ85-Part II can be used in future research concerning social support in adolescents.

摘要:

Caldwell's Home Observation for Measurement of the Environment (HOME) was developed to provide specific and sensitive information about the home and maternal environment as a stimulus to infant learning and development. The use of the HOME scale was examined in a sample of 118 middle- and lower-income mothers and their low-birth-weight (LBW) or very-low-birth-weight (VLBW) infants. The analysis of data demonstrated limited variability in the HOME scale total scores within each income group, and income alone was found to account for 41% of the variance in the sample. These findings raise questions about the effectiveness of the HOME scale in making useful discriminations about family functioning within an income group.

摘要:

The purpose of this study was to examine the concurrent validity of the Whitney strain gage for the measurement of nutritive sucking in preterm infants. Ten preterm infants were studied continuously during at least one entire bottle feeding per week, from admission into the study until discharge from the nursery. Sucking was measured simultaneously by an adapted nipple and the Whitney gage. The two instruments were compared on the following measures: number of sucking bursts, number of sucks per burst, and duration of bursts and pauses between bursts. Total percent agreement for the occurrence of a sucking burst was 99.3% (K = .99). Sucks per burst varied from 2 to 113, with 89.3% of the pairs of sucking bursts differing by ≤ 1 suck per burst. The mean absolute difference between the two instruments for the duration of sucking bursts and pauses was .64 s and .72 s, respectively. These results demonstrate the concurrent validity of the Whitney gage for measurement of sucking events in preterm infants.

摘要:

Self-efficacy has been documented as a strong predictor of health behaviors. Unfortunately, availability of reliable and valid measures of self-efficacy for a range of health behaviors is still limited. This study validated two measures of cardiac risk factor self-efficacy; the Cardiac Diet Self-Efficacy Instrument (CDSEI) and the Cardiac Exercise Self-Efficacy Instrument (CESEI). A sample of 370 cardiac rehabilitation participants provided data for principal factor analyses showing the unidimensionality of each instrument. Known groups construct validity was supported by a comparison of CDSEI and CESEI scores for cardiac rehabilitation participants and marathon runners. The value of CDSEI and CESEI scores in predicting subsequent exercise and diet performance was demonstrated with a third group of cardiac rehabilitation participants. Stability and internal consistency estimates in the .80s and .90s, respectively, support the scales' reliabilities.

摘要:

Factors that influence school achievement in very-low-birth-weight (< 1,500 g) children were investigated at the completion of first grade. The subjects were 71 children and their primary caregivers. Thirty-nine children were very low birth weight (VLBW) and 32 were normal birth weight (NBW). After controlling for birth weight status, over one third of the variance in children's school achievement was accounted for by the age of the child's mother when she began childbearing. Birth weight status accounted for significant amounts of variance in information processing skills. Significantly more children in the VLBW group required special services and fewer were promoted to second grade, although the difference was not significant.

摘要:

Thirty-eight women with breast cancer were studied to determine the psychological distress they experienced at the completion of adjuvant treatment. Measures were completed at the start of adjuvant chemotherapy, one week after chemotherapy was completed, and following completion of radiotherapy. Approximately 30% of the women reported the termination of treatment was upsetting. For the group as a whole, depression scores decreased significantly from the first to the last measurement. Those who were most upset by termination of treatment had been more depressed since the onset of treatment, tended to view their illness as chronic rather than acute, and had more side effects during their last cycle of chemotherapy. Some women stated they were upset by the termination of treatment perse, but many other problems were reported including side effects that had continued after treatment ended.

摘要:

The purpose of this study was to learn how women experiencing preterm labor come to know a health deviation exists, and what they do when faced with such a problem. Grounded theory methodology was used as the research approach. Extensive interviews were conducted with 28 women about their care-seeking experiences with preterm labor. Ambiguous symptoms, absence of a meaningful label to attach to symptoms, and the context of pregnancy with its expected discomforts come together to create a situation of diagnostic confusion. Appropriate action to take in response to the diagnostic confusion is not self-evident. Deliberate and protracted efforts to make sense of and deal with symptoms of preterm labor are attempted. Making sense consists of three subprocesses: comparing, gathering data, and seeking information. Strategies used to deal with the symptoms include self-treating, ignoring, positive thinking, and waiting. Recourse to a professional is used as the strategy of last resort when symptoms can no longer be contained.
