The American College of Nurse-Midwives' Domestic Violence Education Project: evaluation and results.

From October 1994 through September 1998, the American College of Nurse Midwives conducted a nationwide Domestic Violence Education Project. The project aimed to encourage universal screening for domestic violence among all women being seen for care. A four-pronged set of objectives was used, including policy, basic education, continuing education, and advocacy/activism. A description of the project and the results of the project evaluation, including replicable features, are presented. Process and outcome evaluations were performed using both quantitative and qualitative data. Surveys, interviews, and site visits formed the basis for the evaluation of the policy reform, education program, and advocacy components. Pretests and posttests of training participants formed the basis of the evaluation of the continuing education component. All project objectives were met. Policy reform occurred as expected. Changes were noted in education programs in both didactic content and clinical exposure. Changes in clinical behavior as assessed by the pretests and posttests look promising, although numbers of respondents at 12 and 24 months after training are small. Participants reported an increase in advocacy and activism. The Domestic Violence Education Project seems to be a successful and somewhat replicable model for changing attitudes about a health topic (among providers) with possible implications for clinical practice.

Ice massage for the reduction of labor pain.

The current study investigated the use of ice massage of the acupressure energy meridian point large intestine 4 (LI4) to reduce labor pain during contractions. LI4 is located on the medial midpoint of the first metacarpal, within 3 to 4 mm of the web of skin between the thumb and forefinger. A one-group, pretest, posttest design was chosen, which used 100-mm Visual Analog Scales (VAS) and the McGill Pain Questionnaire (MPQ) ranked numerically and verbally to measure pain levels; the pretest served as the control. Study participants were Hispanic and white Medicaid recipients who received prenatal care at a women's clinic staffed by certified nurse-midwives and obstetricians. Participants noted a pain reduction mean on the VAS of 28.22 mm on the left hand and 11.93 mm on the right hand. The postdelivery ranked MPQ dropped from number 3 (distressing) to number 2 (discomforting). The study results suggest that ice massage is a safe, noninvasive, nonpharmacological method of reducing labor pain.

The influence of concept mapping on critical thinking in baccalaureate nursing students.

This article describes a quasi-experimental study that used a pretest-posttest design with a control group to evaluate the effectiveness of concept mapping in developing critical thinking skills in baccalaureate nursing students. A convenience sample (n = 76) was randomly assigned to experimental (n = 44) and control (n = 32) groups. The experimental group was taught to use concept mapping of patient information to prepare for clinical experiences. The control group was taught to use traditional nursing care plans. Critical thinking skills were measured with the California Critical Thinking Skills Test, which yielded six scores: an overall score and five subscales (analysis, evaluation, inference, deductive reasoning, and inductive reasoning). A significant difference (p <.05) was found between the mean pretest and posttest scores and each subscale. Post hoc tests found differences between groups to be insignificant, while various differences within a group were significant. Experimental-group scores improved significantly (p <.05) on the overall score and the analysis and evaluation subscales, while control-group scores improved significantly only on the evaluation subscale and declined significantly on the inference subscale. The findings suggest that concept mapping is effective in helping students develop critical thinking skills.

Treatment outcome among child psychiatric outpatients in a community mental health center.

The study evaluated the effectiveness of mental health center treatments for children aged 5-12 years. The Child Behavior Checklist (CBCL) was administered before and after treatment to the parents of the treatment group (N = 71). The results were analyzed and compared to the results of the pretest and posttest CBCL administered to the parents of a matched group of comparison subjects (N = 33). The results showed that the treatment subjects significantly improved on both the externalizing and internalizing scales of the CBCL. The controls showed no significant change between pretest and posttest scores. As a result, it appears that clinic treatments can help clients with measurable problems decrease problematic behaviors. More data is needed to determine whether clinic treatments such as the ones described in this study can substantially help the most seriously disturbed school-age children.

Response shift in quality of life measurement in early-stage breast cancer patients undergoing radiotherapy.

In medicine, response shift refers to a change--as a result of an event such as a therapy--in the meaning of one's self-evaluation of quality of life. Due to response shift, estimates of side effects of radiotherapy may be attenuated if patients adapt to treatment toxicities. The purpose of our study was to assess to what extent two components of response shift, scale recalibration and changes in values, occur in early-stage breast cancer patients undergoing radiotherapy and to examine what the implications would be for treatment evaluation. In the week before start of post-operative radiotherapy, 46 patients filled out a questionnaire consisting of quality of life items of the SF-36 and the Rotterdam symptom checklist (RSCL) (pretest). During radiotherapy, patients were asked to fill out the questionnaire twice: a posttest (quality of life at that moment) and a thentest (quality of life before treatment, retrospectively), supposedly using the same internal standard. Changes in values were studied by asking the patients on the two occasions to rate the importance of seven attributes representing various domains of quality of life. Patients were also asked whether their quality of life with respect to the measured aspects had changed since the pretest (subjective transition scores). Significant scale recalibration effects were observed in the areas of fatigue and overall quality of life. When the groups were divided according to their subjective transition scores, significant scale recalibration effects were found in case of worsened quality of life for fatigue and overall quality of life, and in case of improved quality of life for fatigue and psychological well-being. The mean importance ratings remained fairly stable over time, except for 'skin reactions', which obtained less importance at the end of radiotherapy than before. In conclusion, effects of scale recalibration were observed that would have significantly affected quality of life evaluations, in that the impact of radiotherapy on fatigue and overall quality of life would have been underestimated. Changes in internal values were observed only for 'skin reactions'.

An Investigation of the Properties of Computer-Based Case Simulations.

Computer-based case simulations (CCS) require several development iterations, each involving a sizeable investment of time from physician volunteers and test development staff. Hence, a case that fails to demonstrate good measurement properties when administered to examinees at the pretest stage represents a costly loss. An earlier study investigated the relationship of case properties to case difficulty in part to obtain information that would permit (a) better instructions to case developers and (b) identification of problematic cases earlier in the developmental cycle. Some of the best predictors, however, were scoring points typically obtained at the pretest stage, making them inappropriate for meeting these two goals. The objective of this study was to determine if these scoring points could be predicted from cases properties that would be available early in case development. Case description variables and scoring points were available for 28 cases which were analyzed using regression procedures. Three models were identified that predicted the important scoring fairly well. These models differed primarily in the area of medicine: internal medicine, obstetrics/gynecology, or no medical area specified. The results were consistent with those found for predicting difficulty and appeared promising for better understanding of the nature of the simulations.

Teaching sedation and analgesia with simulation.

OBJECTIVE: This study reports on the efficacy of using the anesthesia simulator to teach sedation and analgesia to nurses. This provision of sedation and analgesia to a patient is accomplished with the goal of maintaining the ability of the patient to respond purposefully to auditory or tactile stimuli. METHODS: Nurses working in areas of the hospital where conscious sedation is performed were the participants in this sedation and analgesia training course. Prior to the training session, the participants read the American Society of Anesthesiology Practice guidelines for sedation and analgesia by non-anesthesiologists. At the time of the training session, each participant completed a written pretest, had an introduction to sedation and analgesia with four clinical crisis teaching scenarios using the anesthesia simulator, a practical exam using the simulator, and a written post-test. Each participant was also given the opportunity to complete an evaluation of the session. RESULTS: Twenty nurses completed the training session. The written tests had a maximum possible score of 30. Mean score on the written pretest was 22.9 +/- 3.54, and mean score on the written post-test was 26.0 +/- 4.24 (p < 0.001). Seventeen of the twenty subjects scored higher on the post-test. Mean practical exam score was 5.5 of a possible 6.0. Mean participant rating of the education session was 3.75 (1 = poor, 4 = excellent). All but one participant rated the length of the training session as "about right." CONCLUSIONS: The anesthesia simulator provides an excellent tool for teaching conscious sedation skills to hospital nurses. The participants' test performance improved following the session, and they also rated the educational experience as excellent.

Genetics education for primary care providers in community health settings.

Patients who are in need of genetic services are often inappropriately managed, in part due to inadequate knowledge of genetic issues among primary health care providers. The purpose of this study was to determine the effect of a genetics education program on the knowledge and attitudes of primary care providers in community health settings. A total of one hundred twenty-one primary care providers who work in Texas Public Health Region VIII participated in an educational program designed to provide basic genetics information. A one-group pretest-posttest design was used to assess knowledge and attitudes of subjects, and comparisons were made pre and post intervention. Pretest assessment revealed less than adequate knowledge about basic genetic principles and relatively positive attitudes among the subjects. Following the program, there were statistically significant increases in both knowledge about genetic conditions (P = .001) and attitudes toward provision of genetic services (P = .001). These results indicate that primary health care providers, motivated to learn complex materials and new skills in order to assist their patients, can do so in a relatively short time period.

Daubert, cognitive malingering, and test accuracy.

Daubert v. Merrell Dow Pharmaceuticals (1993) held that trial judges should permit expert scientific testimony only when "the reasoning or methodology underlying the testimony is scientifically valid, and ... properly can be applied to the facts in issue." Vallabhajosula and van Gorp ("V & vG," 2001) have suggested that when the Daubert standard is applied to tests for malingered cognitive deficits, courts should deem admissible only results that meet this mathematical standard: assuming a pretest probability of .3, a "positive" score on the malingering test should yield a posttest probability of at least .8. This paper shows that V & vG's criterion may lead to misunderstandings about the kind of information maligering measures provide. After reviewing cases that have discussed both the Daubert decision and malingered cognitive deficits, this paper uses data from the Test of Memory Malingering (T.N. Tombaugh, 1996) to provide a general characterization of the mathematical properties of malingering measures. The paper then describes how pretest knowledge about malingering is combined with knowledge about a test's performance to generate a posttest probability of malingering. The results can help mental health experts respond to Daubert-inspired challenges to conclusions based on malingering measures.

Reducing adolescents' growth in substance use and delinquency: randomized trial effects of a parent-training prevention intervention.

The relationship between growth in adolescent substance use and delinquency was examined in a longitudinal, randomized controlled study of the Preparing for the Drug Free Years Program (PDFY), a universal family-focused prevention intervention. Latent growth curve modeling was used to analyze 5 waves of data collected from 429 rural adolescents. Results showed that adolescents assigned to the PDFY intervention condition had a slower rate of linear increase over time in both substance use and delinquency compared with adolescents assigned to the control condition. Moreover, pretest level of delinquency was a reliable, positive predictor of growth in substance use, whereas pretest level of substance use did not predict growth in delinquency.

Refractive errors and visual impairment in 900 adults with intellectual disabilities in the Netherlands.

PURPOSE: To collect data on refractive errors and visual impairment in adults with an intellectual disability (ID) in the Netherlands. PATIENTS: A randomized sample of 2100 participants was drawn from a base population of 9000 adults with intellectual disabilities in the Netherlands. This article reports on the first 900 participants. METHODS: All participants underwent a protocol-based on-site ophthalmological assessment carried out by skilled investigators. RESULTS: Co-operation was classified according to the number of tests that could be carried out reliably and was good or excellent in 80% of subjects, average in 13% and poor in 7%. Refraction could be reliably assessed in 505/900 (56%) subjects. There was an increased risk of visual impairment in all subgroups compared to the general Dutch population. Visual acuity (VA) was related to the level of ID, but refractive errors were not. New spectacles were prescribed in 106 cases (12%). Of 374 people in whom both monocular VA and the refractive error of the right eye could be reliably assessed, 153 (41%) had a pretest prescription, 16 (10%) of which we found to be inadequate. Of the 221 participants without a pretest prescription, 41 (19%) benefited from correction. Only 38/84 (45%) subjects aged 50 years or older, who could benefit from correction for near vision, had near spectacles. New correction increased the mean distant VA significantly from 0.44 to 0.65 (p < 0.0005). CONCLUSIONS: With some adaptations, visual screening is feasible in a majority of adults with ID. Visual impairment and refractive errors are much more prevalent in adults with ID than in the normal population. Accurate spectacle correction resulted in significant improvement in distant VA.

Self-instruction to prevent HIV infection among African-American and Hispanic-American adolescents.

This study tested the efficacy of self-instruction intervention to reduce avoidable risks for HIV infection associated with drug use and unsafe sexual activity among African-American and Hispanic adolescents (N = 60). After completing pretests, adolescent participants in the study were randomly divided into three conditions. Participants in one condition received a self-instructional guide about AIDS and its transmission along with group instruction in using the guide. Adolescents in another condition received the guide without group instruction. Participants in the third condition received neither the guide nor group instruction. Outcome findings indicate that participants in the two self-instruction conditions improved more between pretest and posttest assessments on measures of HIV infection risk compared with adolescents in the control condition.

Long-term comparison of brief versus unlimited psychodynamic treatments with children and their parents.

Thirty children and their parents were assigned randomly to either time-unlimited or time-limited (12 sessions) psychodynamically oriented treatments or to a minimal-contact control group. All groups showed significant improvements from pretest to posttest. Comparisons between groups at posttest on parental measures of family functioning showed that changes reported by the minimal-contact control group were significantly greater than those of the time-unlimited group. When assessments from pretest to 4-year follow-up were compared, all groups improved significantly on therapist measures of goal attainment, but only the minimal-contact control group reported significant improvements on severity of target problems and measures of family functioning. The results of this study suggest that long-term therapy does not necessarily provide more effective therapy. These findings have important implications for clinical practice, service delivery, and research, particularly in the present climate of financial restraint in health care.

Randomized trial of brief family interventions for general populations: adolescent substance use outcomes 4 years following baseline.

This study examined the long-term substance use outcomes of 2 brief interventions designed for general population families of young adolescents. Thirty-three public schools were randomly assigned to 3 conditions: the 5-session Preparing for the Drug Free Years Program, the 7-session Iowa Strengthening Families Program, and a minimal contact control condition. The pretest involved 667 6th graders and their families. Assessments included multiple measures of initiation and current use of alcohol, tobacco, and marijuana. Pretest data were collected in the 6th grade and the reported follow-up data were collected in the 10th grade. Significant intervention-control differences in initiation and current use were found for both interventions. It is concluded that brief family skills-training interventions designed for general populations have the potential to reduce adolescent substance use and thus have important public health implications.

Effect of brief training on sex-related differences in visual-spatial skill.

Undergraduate students (N = 83) were pretested on four standard tests of visual-spatial skill. Half were given 3 hours of training relevant to the spatial tasks presented by three of the tests. All subjects were then posttested. The hypothesis that spatial "ability" is susceptible to practice and training effects was strongly supported. Multivariate analysis of variance showed that experimental subjects improved significantly more than control subjects, male and females improved equally and substantially, and training effects generalized to an untrained spatial task. The hypothesis that females score lower on spatial tests because they lack relevant practice was also supported; when female experimental subjects were compared with male control subjects on the posttests, the sex-related pretest difference favoring males was eliminated.

A consciousness-sampling analysis of test anxiety and performance.

In order to evaluate cognitive-interference, reassertion, and reaction-to-performance models of test anxiety, 82 students completed the Test Anxiety Scale, provided state measures of anxiety just before and after a course examination, described their preparation for the test, and reported thought content and state anxiety up to six times during the test. Test Anxiety Scale scores were predictive of pre- and posttest state anxiety but not performance or problem-solving thought frequency during the test. Thought content was significantly but weakly correlated with performance, which was well correlated with posttest state anxiety but not with pretest anxiety. Pretest state anxiety was virtually uncorrelated with posttest state anxiety, with the correlations gradually declining during the test. Question-answering thought content correlated inversely with anxiety during the test. There was no group for whom anxiety appeared to facilitate performance. Preparation correlated only with performance. The pattern of results appears inconsistent with a cognitive-interference interpretation of test anxiety and suggests that in the naturalistic setting used, anxiety is more clearly an effect than a cause of poor performance.

The role of predrug signals in morphine analgesic tolerance: support for a Pavlovian conditioning model of tolerance.

According to a model of morphine tolerance, which emphasizes Pavlovian conditioning principles, tolerance results from an association between predrug environmental cues and the systemic effects of the drug. To assess this model, groups of rats were administered morphine on either three or nine occasions, with a complex environmental stimulus either paired or not paired with each injection. Control groups had equivalent experience with the environmental cue and injection procedure, but the injected substance was physiological saline. Subsequently, the analgesic effect of the opiate was tested in all subjects following administration of the drug in conjunction with the environmental cue. As expected on the basis of the conditioning model of tolerance, subjects with a pretest history of paired morphine administrations displayed analgesic tolerance, but subjects with a pretest history of unpaired administration displayed no evidence of such tolerance. The results suggest that prior demonstrations that the display of morphine tolerance is specific to the drug administration environment may be readily interpreted by a conditioning analysis of tolerance.

Aerobics enhances cardiovascular fitness and agility in preschoolers.

Investigated effects of aerobic exercise on a sample of 24 preschoolers. Thirty minutes of aerobic exercises were provided daily for a period of 8 weeks for a group of 12 children while the remaining 12 children engaged in freeplay on the school playground. The children were given pretests and posttests on the following measures: a submaximal exercise test on a pediatric bicycle (baseline and three workloads), an agility test, a health knowledge test, a self-esteem scale, and an observational measure of their gross-motor activity. Despite comparability on pretests, significant group X repeated measures effects suggested that the aerobic exercise group showed decreases in heart rate at all three workloads as well as increases in agility and self-esteem following the exercise program. These findings suggest that cardiovascular fitness, agility, and self-esteem can be facilitated in preschoolers by an aerobic exercise program.
