Excess body weight, especially obesity, is a problem of increasing social significance, and weight gain is often correlated with age. Because physical activity can both decrease current body weight and prevent weight gain, it is an especially suitable target for behavioral intervention. A package intervention consisting of self‐monitoring, goal setting, and feedback was used to increase the physical activity of healthy adults. A combined multiple‐baseline and reversal design was arranged to evaluate the effects of the intervention on the number of steps taken each day by participants, as recorded by a pedometer. The intervention increased the number of steps taken across participants, but there were no changes in participant body weight during the intervention. The results suggest that a relatively simple and low‐cost intervention can be used to increase the physical activity of some adults. Copyright © 2008 John Wiley & Sons, Ltd.  相似文献

ObjectivesA lifestyle physical activity intervention in women based on the transtheoretical model and social–cognitive theory effectively increased physical activity. The aim of the present study was to examine possible mediators (perceived benefits and barriers of physical activity, self-efficacy, processes of change, and social support) of these physical activity changes.MethodsMembers of four units of a women's organization followed a six-month minimal-contact physical activity program. The intervention program included one group meeting, a self-help booklet and five monthly reminder letters. Members of two other units served as control group. Physical activity (accelerometer counts), and psychosocial constructs (self-report questionnaires) were assessed at baseline (pretest) and directly after the intervention (posttest). Women who completed all measurements (n = 101) were included in the mediation analyses.ResultsParticipants in the intervention group reported significantly greater increases in the use of behavioral processes from pretest to posttest than participants in the control group. None of the proposed psychosocial constructs showed a mediating effect on changes in physical activity.ConclusionsThe mechanisms proposed by the transtheoretical model and social–cognitive theory could not explain the positive effect of the intervention on physical activity. Identifying the working components of an intervention remains a challenging and necessary step in the development of effective low-cost and high-reach physical activity interventions.  相似文献

The biomotometer, an electronic device which simultaneously measures motor activity and provides auditory feedback, was used in combination with material reinforcers in an experiment to reduce children's activity level in a classroom setting. Subjects were nine boys and two girls, aged 9–13, from a day hospital program for emotionally disturbed children. After five baseline trials, each child had five contingent reinforcement trials in which he/she received feedback “beeps” from the biomotometer and was given toy or candy rewards after each trial in which activity fell at least 20% below mean baseline level. Then five noncontingent reinforcement trials were run in which children received rewards for wearing the apparatus without the feedback attachment. Results indicated that the intervention “package,” including instructions, feedback, and contingent reinforcement, was successful in all five trials for 8 of 11 children. Activity levels increased during the final noncontingent phase.  相似文献

Research demonstrates that exercise can decrease depressive symptoms, yet it is infrequently prescribed as an intervention. Self-management techniques offer an effective and cost-efficient approach to increase engagement in physical activity. The purpose of this study was to evaluate the efficacy of goal setting, self-monitoring, and feedback for increasing daily step count in university students (N = 4) reporting depressive symptoms. The treatment was efficacious for increasing steps for three participants with varying levels of consistency. All participants showed a decrease in some depression symptoms on the University Student Depression Inventory. Expert ratings on the Clinical Global Impression Scale indicated improvement in global functioning for three participants. Additional research is needed to determine the efficacy of this intervention package for increasing daily steps and the relation to depression symptoms.  相似文献

PROBLEM: Physical activity has been promoted as a means of enhancing self-concept, yet the evidence for this connection is far from compelling. In particular, experimental research investigating this association during adolescence, a period during which many youth struggle to maintain a positive self-image, is noticeably lacking. This study investigates the impact on self-concept of a 9-month physical activity intervention among sedentary adolescent females. METHOD: Female adolescents who were sedentary at baseline were assigned either to an exercise intervention or a comparison group as part of the controlled trial. The intervention was school-based, and assignment to groups was based on school attended. Intervention participants engaged in supervised activity 4 times per week and received didactic instruction promoting activity outside of school 1 day per week. Self-concept, physical activity participation, and cardiovascular fitness were assessed before, mid-way through, and after the 9-month intervention. RESULTS: The intervention had a significant positive impact on participation in vigorous activity and cardiovascular fitness. The intervention did not significantly influence any of the self-concept dimensions overall. There was, however, a three-way interaction such that there was an increase in global physical self-concept among those intervention participants who increased cardiovascular fitness. CONCLUSIONS: These findings indicate that a physical activity intervention among sedentary adolescent females enhanced global physical self-concept for a subset of intervention participants who manifested positive changes in fitness.  相似文献

We evaluated a staff training and management package for increasing accuracy of recording frequency of problem behavior in a residential care facility. A multiple baseline design across the first and second work shifts showed that 2 of 8 participants increased their accuracy following in-service training, and all 8 improved during a condition with supervisor presence and feedback. Improvements were maintained when feedback was removed and generalized to activity periods when neither supervisor presence nor feedback was provided. Other staff behavior was not adversely affected by the intervention package.  相似文献

The study investigated the effectiveness of an intervention package consisting of self‐monitoring and video modeling to increase on‐task behavior during independent seatwork time in math. Four students in either the second or third grade, identified as displaying high rates of off‐task behavior by their classroom teacher, were included in the study. Results showed immediate, large, and durable changes in on‐task behavior for each of the four participants. At baseline, on‐task behavior of the participants while working on independent math assignments was displayed in 47% of the intervals observed. During the intervention, the participants' average rate of on‐task behavior increased to 85% of the intervals observed. Mean Busk and Serlin (1994) effect size for all four participants was 5.60, with a percentage of non‐overlapping data points effect size of 100%. Observations of the participants 3 weeks following the termination of the study showed that the gains in on‐task behavior were maintained. Both teacher and participant feedbacks concerning the use and effectiveness of the intervention package were positive. Results of the investigation suggest that the intervention package may be an effective and socially valid method for addressing off‐task behaviors of students within the classroom.

Peer interactions are among the greatest challenges experienced by children who have severe emotional and behavioral problems. This study evaluated an intervention package designed to increase the ratio of these children's desirable to undesirable interactions. The package included three principal components: (a) observation of videotapes following regularly scheduled peer activity sessions; (b) self-evaluation of the children's peer interactions observed on the videotapes; and (c) delayed feedback and reinforcement for desirable peer interactions. Five students from two elementary schools participated. Multiple baseline designs and one reversal were used to evaluate the effects of the intervention package. The results showed that the intervention produced lower levels of undesirable peer interactions and higher ratios of desirable to undesirable interactions for all participants. The results are discussed in regard to their conceptual and applied implications and in terms of specific directions for future research.  相似文献

Abstract

The purpose of the study was to assess the effectiveness of a goal-setting package on objective and subjective measures of speed skating performance. Participants were four female skaters ranging in age from 12–17 years. A single-subject design, the multiple baseline across individuals, was used to evaluate the intervention package. One participant remained at baseline for the duration of the study to control for training effects. The results provide support for utilizing a goal-setting package in an athletic setting. During practices, laps and drills completed increased, while off-task behaviors decreased. Racing times obtained in practice and competitions improved for all three experimental participants. A social validity assessment provided further support for the effectiveness of the intervention.  相似文献

The objectives were a) to test whether a Processes of Change (POC)-personalized Transtheoretical model (TTM)-based intervention could increase physical activity (PA) among inactive adults, and b) to examine whether the intervention increased the level of TTM theoretical constructs. The following hypotheses were formulated: 1) PA levels will be significantly higher during and after the intervention in comparison to baseline measures; 2) the level of targeted POCs will increase during the intervention; 3) non targeted POCs will stay stable, and 4) self-efficacy and decisional balance levels will increase during the intervention. A series of N-of-1 with A (1 to 2-week)-B(10-week)-A'(2-week) design were conducted with 12 inactive adults. Behavioral counselors used behavior change techniques to target TTM constructs and supervise PA. Interventions were individualized based on the 5 POCs with the lowest pre-intervention level. Device-based and subjective PA along with TTM measures were collected weekly online. PA data were analyzed with piecewise linear models. A visual analysis was run to examine the TTM constructs. Device, self-reported and TTM data were available for five, seven and five participants, respectively. A significant self-reported PA increase for six participants was found during the phase B and A2. A significant device-measured PA increase was observed in two participants during the study. A substantial increase of targeted POC from baseline for all participants with available data was observed. This study provides the first evidence of behavioral and psychological effects of a POC-personalized TTM-based intervention in inactive adults.  相似文献

A Social Stories intervention package was used to teach 2 students with autism to read Social Stories, answer comprehension questions, and engage in role plays. Appropriate social behaviors increased and inappropriate behaviors decreased for both participants, and the effects were maintained for up to 10 months. This intervention package appears to be useful in inclusive classroom environments and does not require intensive supervision of the child's behavior.  相似文献

Past research has demonstrated that health behavior is correlated with time perspective: long-term thinkers are more likely than short-term thinkers to engage in health protective behaviors and less likely to engage in health damaging behaviors. To date, however, no research has experimentally demonstrated that time perspective is causally related to health behavior. We designed a brief (three 1/2-h weekly sessions) time perspective intervention to enhance long-term thinking about physical activity and examined its efficacy among two samples of young adults who signed up for fitness classes at a university recreational facility. Participants were assigned to one of three conditions: time perspective intervention, goal-setting control intervention, and no-treatment control. In Study 1, physical activity levels were assessed at preintervention, at postintervention (3 weeks later), and at 10-week follow-up (7 weeks after completion of the intervention). Controlling for preintervention physical activity levels, time perspective participants reported increased levels of physical activity relative to both other groups at postintervention, and relative to the no-treatment group at 10-week follow-up. This study provides the first experimental evidence that the effects of health behavior interventions may be enhanced by increasing participants’ long-term time perspective, and that time perspective is causally associated with health behavior. Study 2 replicated some of the effects of Study 1 using a larger sample, a six-month follow-up interval, and improved measurement of outcome. Together Studies 1 and 2 suggest that time perspective is an important ingredient in interventions designed to promote physical activity.  相似文献

We measured changes in physical activity in 2 obese preschool children when a package intervention was evaluated in a reversal design. Physical activity was measured via direct observation and pedometers. Although the intervention produced only modest increases in activity, the results provide preliminary concurrent validation for the dependent measures used, in that the two measures covaried and a similar degree of change was observed with each across baseline and intervention phases.  相似文献

OBJECTIVE: Given that only 25% of Americans meet physical activity recommendations, there is a need to develop and disseminate effective, evidence-based interventions to promote physical activity. The authors tested 2 delivery channels, telephone and print, to determine whether one was more effective in promoting physical activity. DESIGN: The authors randomly assigned 239 healthy, sedentary adults to (a) telephone-based individualized feedback, (b) print-based individualized feedback, or (c) contact control. Both intervention arms were guided by a motivationally tailored, theoretically driven computer expert system. MAIN OUTCOME MEASURES: Physical activity as measured by the 7-day Physical Activity Recall interview. RESULTS: At 6 months, both telephone and print arms significantly increased in minutes of moderate intensity physical activity compared with control, with no differences between the intervention arms. At 12 months, print participants reported a significantly greater number of moderate intensity minutes than both telephone and control participants, who did not differ. CONCLUSION: Results suggest that both telephone and print enhance the adoption of physical activity among sedentary adults; however, print interventions may be particularly effective in maintaining physical activity in the longer term.  相似文献

The purpose was to examine the effectiveness of a physical activity intervention which combined behavior-change strategies with a variety of physical activities for 30 sedentary adults in a 12-wk. intervention that included behavior-change strategy sessions and supervised physical activity. Before and after the intervention, psychological and physiological variables were measured. Statistically significant changes right after the intervention included (1) an increase in physical activity participation, (2) an increase in muscular endurance, flexibility, and predicted VO2 max, and (3) a decrease in the number of barriers to physical activity. Changes in physical self-perception, a psychological variable often linked to increased physical activity, were not statistically significant, but effect sizes were large. The use of behavior-change strategies in conjunction with a variety of physical activities may be useful in improving physical and psychological well-being in previously sedentary adults. Stability of change requires study.  相似文献

Objective: Physical activity is a key factor for healthy ageing, yet many older people lead a sedentary lifestyle. Traditional physical activity interventions do not consider the specific needs and views of older adults. As views on ageing are known to be related to health behaviours, the current study evaluates the effectiveness of prompting positive views on ageing within a physical activity intervention.

Design: Randomised controlled trial with three groups aged 65+: Intervention for physical activity with ‘views-on-ageing’-component (n?=?101; IGVoA), and without ‘views-on-ageing’-component (n?=?30; IG), and active control intervention for volunteering (n?=?103; CG).

Main outcome measures: Attitudes towards older adults and physical activity were assessed five weeks before intervention, two weeks, six weeks and 8.5?months after the intervention.

Results: Compared to the IG and CG, positive attitudes towards older adults increased in the IGVoA after the intervention. For IGVoA, the indirect intervention effect on change in activity via change in attitudes towards older adults was reliable.

Conclusion: A ‘views-on-ageing’-component within a physical activity intervention affects change in physical activity via change in views on ageing. Views on ageing are a promising intervention technique to be incorporated into future physical activity interventions for older adults.  相似文献

This article reports the development and exploratory testing of a school-based intervention programme designed to enhance levels of physical activity in adolescents. The intervention is based on social cognitive theory (SCT), self-regulation theory (SRT) and planning as evidence-based mediators of physical activity changes. Two classes, paired on socio-economic variables, were selected from each of eight Portuguese schools and randomly assigned to an intervention or control group (N = 291). Primary outcome was ‘moderate to vigorous physical activity’ (International Physical Activity Questionnaire) measured pre and post intervention and at three and nine months follow-up. SCT, SRT and planning variables were secondary outcomes measured pre and post intervention. At post test, participants in the intervention group reported 18 min per week more physical activity (PA), adjusted for pre-intervention, age and sex, than those in the control group (95% confidence interval ?10 to 46; p = 0.249). This difference increased to 33 min (95% CI–4 to 71; p = 0.082) at three months and to 57 min (95% CI 13 to 101, p = 0.008) at nine month follow-up. Moreover, the intervention resulted in changes of some of the theoretical target variables, including outcome expectancies and coping planning. However, no evidence was found for the changes in theoretical moderators to mediate the intervention effects on behaviour. Implications for theory and for future research are discussed.  相似文献

This study evaluated the year-round effectiveness of need-supportive physical activity counseling on various dimensions of subjective well-being. Flemish adults who did not attain the recommended level of physical activity were assigned to an intervention (n?=?92) or a control condition (n?=?34). Participants of the intervention condition received a four-month physical activity coaching based on the Self-Determination Theory. The coaching was limited to five individual contact moments with a bachelor in kinesiology specializing in health-related physical activity counseling. Self-reports on various intensities of physical activity and physical and psychological well-being were completed before (i.e. pre-test), immediately after (i.e. post-test) and 1 year after (i.e. follow-up-test) the intervention. Repeated measurements ANOVAs showed significant time by condition interaction effects with respect to physical well-being. More specifically, physical well-being significantly increased in the intervention condition from pre- to post-test and from pre- to follow-up-test, whereas no changes occurred in the control condition. Bootstrapping mediation analyses revealed that the changes in physical well-being were mediated by changes in strenuous intensity physical activity. The findings demonstrate the year-round effectiveness of need-supportive physical activity counseling with a limited number of contact moments on (physical) well-being and suggest its potential as a public health initiative.  相似文献

The purpose of this study was to examine how an early literacy intervention, Kindergarten Peer-Assisted Learning Strategies (K-PALS; Mathes et al. Kindergarten peer-assisted literacy strategies (K-PALS): Sopris West, 2001), can be intensified to extend the positive outcomes to students who do not initially demonstrate an adequate response to intervention. K-PALS was intensified by incorporating a self-monitoring package that included self-graphing. An alternating treatment design was used to compare the effectiveness of K-PALS with self-graphing alone and K-PALS with a self-monitoring package to baseline/K-PALS for the purpose of increasing student performance on the early literacy measure of phonemic awareness. The results of the study indicate that while the self-monitoring package was the more effective intervention for two of the three student participants, the self-graphing alone intervention also resulted in positive outcomes for both of these participants. There was no change in the phonemic awareness performance for the third participant throughout the alternating treatment phase. Implications for intensifying academic interventions within the context of a Response to Intervention framework are discussed.
