Overserving at licensed premises in Stockholm: effects of a community action program.

OBJECTIVE: The aim of this research was to study the sustainable effects of a community action program on alcohol service to intoxicated patrons at licensed premises. METHOD: Since 1996, the hospitality industry and authorities in Stockholm, Sweden, have been cooperating to reduce problems related to alcohol consumption at licensed premises. The intervention has included community mobilization, training in responsible beverage service (RBS) and enforcement. A pretest in 1996 and follow-ups in the 1999 and 2001 designs were used to study licensed premises in Stockholm. Male actors portraying intoxicated patrons visited the licensed premises and attempted to order beer. Observers were present at each visit. At the pretest, 92 licensed premises were visited, 47 in north central Stockholm and 45 in south central Stockholm. In 1999, 103 establishments were visited, 61 in north central Stockholm and 42 in south central Stockholm. At the latest follow-up in 2001, 100 licensed premises were visited, 56 in north central Stockholm and 44 in south central Stockholm. RESULTS: The results from the latest follow-up in 2001 showed a statistically significant improvement over those of earlier measures, with a refusal rate of 70% compared with 47% in 1999 and 5% in 1996. There were improvements in both study areas (i.e., north and south central Stockholm). CONCLUSIONS: There has been a significant improvement in the rate of refusal of alcohol service at licensed premises in Stockholm during the project period. The reason for this is probably a combination of the intervention efforts: community mobilization, RBS training and a more efficient monitoring of alcohol service by authorities.

When children die: a seminar series for pediatric residents.

OBJECTIVE: Our goals were to assist residents in acquiring skills needed to care for children at the end of life and to increase their comfort level regarding critical aspects of caring for dying children. METHODS: We designed and implemented a 6-part seminar series for pediatric residents in their postgraduate year-2 at the University of Arizona Pediatric Residency Program. The series consisted of small group sessions regarding medical and legal issues facing physicians at the time of a pediatric patient's death, symptom management in dying children, approaches to limitation of care and discussion of impending death of a child, cultural and developmental factors impacting on the care of children at the end of life, parent and sibling bereavement after the death of a child, and physician's personal responses to the death of pediatric patients. The sessions were conducted on weekday evenings away from patient care settings and included input from community-based individuals as well as academic pediatric subspecialists. To promote active discussion, size was limited to 12 participants. Pretests and posttests were used to evaluate the success of this program. Residents' level of comfort with important issues in end-of-life care was measured using a 5-point Likert scale. RESULTS: Although most of the residents taking part in the seminar series had previously participated in discussions of limitation of care of a child and/or had performed advanced life support measures on a child, few had any previous training in end-of-life care. Responses of the 8 participants who completed both the pretests and posttests were evaluated for assessment of changes in comfort level in areas pertinent to end-of-life care. We found that on completion of this program, residents were significantly more comfortable with logistic issues and symptom management, discussing death and limitation of medical care with families, discussing end-of-life care with colleagues and families, handling conflicts within the health care team, working with families of varying ethnic backgrounds, guiding developmentally appropriate discussions of death, identifying and seeking out advice from a role model regarding end-of-life care, and coping with their own responses to a child's death. Costs of this seminar series were minimal. CONCLUSIONS: An inexpensive, discussion-based seminar series successfully provided pediatric residents with basic information regarding end-of-life care and significantly increased their confidence as clinicians caring for seriously ill and dying children.

Translation, adaptation and validation of the Roland-Morris questionnaire--Brazil Roland-Morris.

The purpose of the present study was to translate the Roland-Morris (RM) questionnaire into Brazilian-Portuguese and adapt and validate it. First 3 English teachers independently translated the original questionnaire into Brazilian-Portuguese and a consensus version was generated. Later, 3 other translators, blind to the original questionnaire, performed a back translation. This version was then compared with the original English questionnaire. Discrepancies were discussed and solved by a panel of 3 rheumatologists and the final Brazilian version was established (Brazil-RM). This version was then pretested on 30 chronic low back pain patients consecutively selected from the spine disorders outpatient clinic. In addition to the traditional clinical outcome measures, the Brazil-RM, a 6-point pain scale (from no pain to unbearable pain), and its numerical pain rating scale (PS) (0 to 5) and a visual analog scale (VAS) (0 to 10) were administered twice by one interviewer (1 week apart) and once by one independent interviewer. Spearman's correlation coefficient (SCC) and intraclass correlation coefficient (ICC) were computed to assess test-retest and interobserver reliability. Cross-sectional construct validity was evaluated using the SCC. In the pretesting session, all questions were well understood by the patients. The mean time of questionnaire administration was 4 min and 53 s. The SCC and ICC were 0.88 (P<0.01) and 0.94, respectively, for the test-retest reliability and 0.86 (P<0.01) and 0.95, respectively, for interobserver reliability. The correlation coefficient was 0.80 (P<0.01) between the PS and Brazil-RM score and 0.79 (P<0.01) between the VAS and Brazil-RM score. We conclude that the Brazil-RM was successfully translated and adapted for application to Brazilian patients, with satisfactory reliability and cross-sectional construct validity.

Development of an instrument to measure beliefs and attitudes from heart valve disease patients.

The objective of this study was to verify content validity and reliability of "CAV-Instrument" -- an instrument to measure beliefs and attitudes of heart valve disease patients concerning their illness and treatment. The instrument was analyzed by three judges (using predetermined criteria) and submitted to the pretest (n = 17 subjects). The majority of the items were evaluated as adequate regarding their pertinence, clearness and significance regarding the analyzed questions. The pretest showed the necessity for small changes in some statements, which optimized instrument comprehension by the patients. The restructured instrument was applied to 46 patients to verify internal consistency. The whole instrument and most of its scales presented satisfactory internal consistency. It is concluded that the instrument has content validity and is internally consistent, ratifying the adequacy of its application to measure the strength of association among the researched variables.

Antenatal voluntary counseling and testing for HIV in Barbados. Success and barriers to implementation.

OBJECTIVE: To determine the success of voluntary counseling and testing (VCT) for HIV and to identify the barriers to implementation when VCT is offered as a package integrated with antenatal care. METHODS: In this descriptive study we investigated antenatal VCT and HIV testing in all post-parturient women at the Queen Elizabeth Hospital, Bridgetown, Barbados, who gave birth between April and September 2002. Data were collected retrospectively from the antenatal care record and by recall during one-on-one interview. RESULTS: Of 1 342 women surveyed, 954 (71.1%) received antenatal counseling and were offered an HIV test. Of the 954 women offered HIV test after counseling, 914 (95.8%) agreed to have the test. Among the women surveyed, 1 106 (82.4%) had a documented HIV test, 914 (85.7%) were tested after documented pretest counseling, and another 192 (14.3%) were tested without documented pretest counseling. Overall, 822 of the 1 342 women surveyed (61.2%) had a documented HIV test result in their antenatal case record at the time of delivery. Of the 1 106 women who had a documented HIV test, the test results were unavailable at the time of delivery in only 284 (21.2%). Among the reasons for unavailability of a documented HIV test result, the most common (45.0%) was that no test was done, followed by unclear documentation of the result. CONCLUSIONS: Twenty-nine percent of surveyed women failed to receive antenatal VCT and this is a cause of concern, for both the high coverage and good quality counseling are key to the overall success and cost effectiveness of the VCT program. Fourteen percent of the women surveyed who did not receive VCT were tested for HIV, a situation that is undesirable because some women may be tested without understanding the full implication of this policy, and as a result the overall impact of VCT may be reduced.

Randomized controlled trial of kangaroo care: cardiorespiratory and thermal effects on healthy preterm infants.

PURPOSE: To determine the safety and effects on healthy preterm infants of three continuous hours of kangaroo care (KC) compared to standard NICU care by measuring cardiorespiratory and thermal responses. DESIGN: Randomized controlled trial-pretest-test-posttest control group design. SAMPLE: Twenty-four healthy preterm infants (33-35 weeks gestation at birth) nearing discharge. Eleven of the infants received KC; 13 received standard NICU care. MAIN OUTCOME VARIABLES: Heart rate, respiratory rate, oxygen saturation, and abdominal skin temperature were manually recorded every minute. Apnea, bradycardia, periodic breathing, and regular breathing were captured continuously on a pneumocardiogram printout. Three consecutive interfeeding intervals (three hours each) on one day constituted the pretest, test, and posttest periods. RESULTS: Mean cardiorespiratory and temperature outcomes remained within clinically acceptable ranges during KC. Apnea, bradycardia, and periodic breathing were absent during KC. Regular breathing increased for infants receiving KC compared to infants receiving standard NICU care.

Cost as a barrier to condom use: the evidence for condom subsidies in the United States.

OBJECTIVES: This study sought to determine the impact of price on condom use. METHODS: A program based on distribution of condoms at no charge was replaced with one providing low-cost condoms (25 cents). Pretest and posttest surveys asked about condom use among persons reporting 2 or more sex partners. RESULTS: At pretest, 57% of respondents had obtained free condoms, and 77% had used a condom during their most recent sexual encounter. When the price was raised to 25 cents, the respective percentages decreased to 30% and 64%. CONCLUSIONS: Cost is a barrier to condom use. Free condoms should be distributed to encourage their use by persons at risk for HIV and other sexually transmitted diseases.

Evaluation of a dutch educational "Driving While Intoxicated (DWI)" prevention program for driving schools.

A DWI prevention program for driving schools consisting of a videotape, slides, a textbook, and a manual was developed and evaluated. Effects of the program on knowledge, attitude, behavior intention, and self-reported DWI behavior were measured by means of a pretest, posttest, one-year follow-up evaluation design. Two-hundred and eight driving school students followed the program and participated in all three measurements. A control group of 228 pupils followed a traditional curriculum without the DWI program and also participated in all three measurements. Principal findings were that knowledge improved, attitudes and behavior intentions were already positive at pretest, DWI was equally reported by both groups, and there was a positive effect on riding with an intoxicated driver.

Short-term substance abuse prevention in jail: a cognitive behavioral approach.

This article describes a cognitive-behavioral program for substance abusers which was first implemented in the Baltimore City Jail in 1987. Similar but separate programs are provided for male and female inmates, consisting of twelve to sixteen contact hours over three to four weeks. In addition to conventional drug and alcohol information (physiologic and psychological effects, treatment options), the program emphasizes cognitive and behavioral skills which can prevent substance abuse, including training in consequential thinking, and stress and anger management. Over a two-year period, 607 males and 131 females were served, of whom 429 (59%) completed the entire program. Both males and females showed statistically significant improvement from pretest to posttest in all knowledge areas. Inmates gave high ratings to the program and group leaders reported substantial change in client attitudes toward drug and alcohol use. Knowledge scores at the end of the program were highest for those who scored higher at pretest, rated their group leader higher, and were rated by their group leader as more active participants. Client participation was the strongest predictor of program outcome.

Investigation of the effect of acepromazine on intravenous glucose tolerance tests in dogs.

OBJECTIVE: To investigate the effects of administration of acepromazine on IV glucose tolerance tests (IVGTTs) in dogs. ANIMALS: 8 male mixed-breed dogs. PROCEDURE: With a 1-week interval between tests, each dog underwent (in random order) an IVGTT with or without pretest administration of acepromazine maleate (0.1 mg/kg, SC, 30 minutes prior to the start of the IVGTT). Food was withheld from the dogs for 14 hours prior to each test. Blood samples were obtained at 20, 10, and 1 minute prior to and at 2, 3, 4, 5, 6, 8, 10, 12, 14, 16, 19, 22, 25, 30, 40, 50, 60, 70, 80, 90, 100, 120, 140, 160, and 180 minutes after administration of glucose. RESULTS: There were no significant differences in the baseline (ie, after food was withheld) plasma glucose, lactate, and insulin concentrations between dogs undergoing the IVGTT and acepromazine-IVGTT; however, lower baseline free fatty acid concentration was observed in acepromazine-treated dogs. Analysis of data via the application of Bergman's minimal model of glucose kinetics revealed no differences in insulin sensitivity, acute insulin response to glucose, disposition index, or glucose effectiveness between dogs treated or not treated with acepromazine before testing. CONCLUSIONS AND CLINICAL RELEVANCE: Results indicated that in dogs undergoing IV glucose tolerance testing, pretest administration of small doses of acepromazine can be used as a means of chemical restraint without interfering with results of the glucose metabolism assessment.

Suppression of visual observing by rhesus monkeys produced by conditioned aversive visual stimuli.

Nine rhesus monkeys were tested in a visual observing situation to determine the influence of conditioned aversive visual stimulation. A set of meaningless visual stimuli was selected on the basis of cumulative frequency and cumulative duration of observing during a pretest phase of the experiment. Three subsets of stimuli (low, medium, high) were formed indicating level of observing during pretesting. A portion of the "medium" category of slides then served as conditioned stimuli in a classical conditioning procedure by being paired with electric shock. Following conditioning the entire set of stimuli was again presented in a visual observing situation. The results showed a significant decrease in both frequency and duration of observing of the slides with conditioned aversive qualities, relative to non-shock control slides. These findings support an aversion-produced suppression of observing relatively unconfounded by methodological, procedural, and other differences existing among previous reports on the role of fear or anxiety in this context.

Effect of practice and training in spatial skills on embedded figures scores of males and females.

The effect of practice and training in spatial skills on scores obtained by male and female students on the Embedded Figures Test was examined. Forms A and B were administered 6 wk. apart to three groups of subjects (ns = 28, 27, 27) enrolled in drafting, mathematics, and liberal arts courses. During the pretest-posttest period the drafting students received training while the other two groups served as controls. Analysis indicated (1) no initial sex difference in test scores; (2) liberal arts students differed significantly from drafting and mathematics students, but there was no significant difference between the last two groups; (3) all groups improved with practice; (4) women receiving training improved more than women who did not; (5) there was a trend toward women receiving spatial training scoring more poorly than males receiving training on the pretest, but there was no significant difference on the posttest. These results suggest that sex differences in embedded-figures scores found by many previous experimenters may have been associated with differences in prior experience in spatial skills and by a confounding of sex with area of academic study.

Enhancement of visual perception under conditions of short-term exposure to sensory isolation: a comparison of procedures for altering vigilance.

An experiment was conducted to determine the pre- and posttest performance of subjects on a signal-detection task for the following three experimental conditions: sensory isolation, sensory alertness, and sensory relaxation. All subjects were assessed on 36 pretest and 36 posttest trials. Each block of 36 trials consisted of 12 "strong signals," 12 "weak signals," and 12 "no signals." Exposure durations for each experimental condition lasted for one hour. Analyses showed significant improvements in hits from the pretest trials to the posttest trials on the "strong" and "weak signals" for the sensory isolation condition. Moreover, on the posttest "weak signal" trials, subjects in the sensory isolation condition scored a significantly greater number of hits than did those in the sensory alertness or sensory relaxation conditions. It was concluded that sensory isolation produces perceptual enhancement, as measured by a signal-detection task.

Effects of variable practice on retention and motor schema development in Down syndrome subjects.

Portions of Schmidt's schema theory, the effects of variable practice on retention and ability to learn a novel motor task, were tested using Down syndrome subjects. 23 subjects ranged in mental and chronological ages from 3.0 to 5.1 yr. and 4.6 to 22 yr., respectively. IQs ranged from 32 to 62. The two throwing tasks were closed, discrete movements requiring no feedback or error detection during movement. Subjects were randomly assigned to a specific-practice, variable-practice, or control group. Specific group subjects practiced 100 trials from the test-target location. Variable-practice subjects also practiced 100 trials but from four different practice locations. The control group practiced an unrelated kicking activity. All subjects participated in identical pretests, posttests, and retention tests to assess accuracy on these throwing tasks. A standard archery target was used to score tosses. To examine the effects of practice on a novel task, two target conditions, or tasks, were employed. On Task A the subject tossed a bean bag at the archery target placed flat on the floor. For Task B, the novel task, the target was placed upright on the wall. Subjects were assigned higher scores for tosses landing closer to the center of the target. Analysis of variance indicated no significant differences between groups on Task A pretest or posttest. Significance was detected for the main effect of group for Task B. However, the Scheffé post hoc test indicated that the simple main effects were nonsignificant. This research did not support Schmidt's schema theory.(ABSTRACT TRUNCATED AT 250 WORDS)

Locus of control and alcohol placebo effects on performance in a driving simulator.

Performance in a driving simulator was evaluated as a function of locus of control, perceived alcohol ingestion (no alcohol versus a no-alcohol placebo), and sex. Using a pretest-posttest design, an analysis of covariance was performed using the pretest performance on a driving simulator as the covariate. There were 10 men and 10 women in each of four groups. As predicted, the external-scoring placebo subjects made more posttest errors than did the internal-scoring placebo group or either of the no-alcohol control groups. This indicated that the external-scoring placebo subjects were more affected by what they expected to happen than their actual physiological state warranted. A difference was also found in which external-scoring women made more errors than did any other group. This was an unexpected finding which, being inconsistent with previous findings involving sex, warrants further research.

Effect of educational kinesiology upon simple response times and choice response times.

The purpose of this study was to determine whether Educational Kinesiology integration movements or repatterning in conjunction with the integration movements affect the response times of college students to a visual stimulus. Ten men and ten women were randomly assigned to each of the three conditions: control, Edu-K movement, or repatterned Edu-K movements. Each subject was pretested on simple and choice response-time tasks. Following the pretest, subjects in the control group sat quietly for 10 minutes. The movement group utilized seven Brain Gym activities. Subjects in the repatterned group experienced Dennison's Laterality Repatterning prior to doing the same Brain Gym activities. All subjects were then retested to assess changes in performance using 30 trials of each task. Statistical analyses indicated significant differences in improvement between the groups on the 4-choice task, with the repatterned group showing greater change than the Edu-K movement-only group, who in turn showed greater improvement than the control group. The groups improved by 6%, 3 1/2%, and 1%, respectively. No group differences were significant on the simple task, although a similar trend was indicated. Men responded faster than women on both tasks; however, the amount of improvement was similar for both.

Influence of ball weight on junior high school girls' volleyball performance.

This study was designed to investigate the influence of a lighter ball (Tachikara Volley Lite) on 72 seventh-grade girls' tournament game play and pretest-to-posttest improvement for a 16-day volleyball practice period. Two intact classes were randomly assigned to groups, one of whom used lighter balls during skills progressions while a second used regulation balls. All students used regulation balls during tournament game play and skills tests. Both groups significantly improved the forearm pass from pretest to posttest. Analysis of covariance indicated no significant differences between groups on posttest means for any skill. A 2 x 6 (treatment x game day) analysis of variance indicated that the group practicing with lighter balls had significantly more correct sets and a higher average daily success rate for the set and underhand serve on game days than the group using a regulation ball.

Improvements in horizontality performance as a function of type of training.

90 undergraduates with low spatial perceptual ability were assigned to one of three groups of control, learner-guided instructions, and tutor-guided instructions. The groups differed in amount and type of spatial training administered in a laboratory setting. Participants completed horizontality and vertically spatial perceptual tasks immediately after pretesting and again one month later. Both groups given training showed more accurate performance at posttest than at pretest. In addition, the learner-guided instruction group outperformed the tutor-guided instruction group and control group at posttest and on novel but related tasks. Gender differences in posttest performance favoring males (n = 35) were obtained in the tutor-guided performance group and control group but not in the learner-guided instruction group. The number of hints the latter needed during training was predictive of posttest performance. Implications for assessment and remediation of undergraduates' spatial perceptual abilities are discussed.
