The Transtheoretical Model (Prochaska & Marcus, 1994) has been widely used as a framework for understanding exercise behavior change. The purpose of this study was to clarify equivocal research findings reported for model predictions when examining stage movement over time rather than static stages and to provide some evidence of the construct validity of transitional stages. Participants were female (n = 285) and male (n = 243) undergraduates (M age = 19.9 years, SD = 2.7) who completed previously validated questionnaires twice, separated by 9 weeks, that assessed stage of change, exercise behavior, processes of change, pros and cons of exercise, and exercise self-efficacy. Participants were classified into one of five transitional shift groups based on their responses at baseline and follow up: (a) stable sedentary, (b) stable active, (c) activity adopters, (d) activity relapsers, and (e) perpetual preparers. Results of a 5 (group) x 2 (time) repeated measures (RM) analysis of variance (ANOVA) examining exercise behavior revealed a significant interaction (p < .001) and supported transitional stage classification, with activity adopters and stable actives increasing exercise over time and relapsers decreasing activity. Separate 5 (group) x 2 (time) RM ANOVAs examining model constructs revealed no significant interaction for cognitive processes of change; however, activity adopters and stable actives reported significant (p < .01) increases in the use of behavioral processes over time, while only the activity relapsers and perpetual preparers reported decreases. Activity relapsers also reported significant (p < .05) decreases in the pros of exercise. No significant interactions were found for the cons of exercise behavior. Unlike findings reported in cross-sectional studies, increases in self-efficacy did not accompany increases in exercise stage. The findings strongly support examination of stage movement classifications rather than static stages, as these transitions provide greater insight into the mechanisms of exercise behavior change.  相似文献

The purpose of this study was to examine evidence for the validity of a stages of change measure of the Transtheoretical Model for exercise behavior. Participants were 152 university students (53.3% women, 71.6% Caucasian, M age = 19.18 years) who completed processes of change, self-efficacy, decisional balance, stages of change, and exercise behavior questionnaires as well as a maximal treadmill test. Participants in the action and maintenance stages had the highest strenuous (PC/C/P < A/M) and moderate (PC/C < A/M) self-reported exercise behavior. Those in the maintenance stage had the highest estimated aerobic fitness (PC/P < MA). The differences between the early stages (PC, C, and P) and the later stages (A and M) as described by the first function were primarily due to the behavioral process of change. The differences between the extreme stages (PC and M) and the middle stages (C, P, and A) were due to the experiential processes of change and the pros of decisional balance. The hypothesized patterns of stage differences were partially supported. Failure to obtain full support may have been due to methodological issues or inherent difficulties in detecting evidence for the validity of stages of change measures.  相似文献

Validating motivational readiness for exercise behavior with adolescents.   总被引:1,自引:0,他引:1  
The stages of motivational readiness as conceptualized by the Transtheoretical Model have been widely used among adult samples to assess readiness for adopting exercise behavior. To date, little research has been conducted using a staging framework with adolescent samples. There is a need for validation of the staging framework prior to a substantial amount of research with this age group. The current article presents two studies assessing stage and reported exercise behavior (Study 1: n = 819; M age = 15.0 years, SD = 1.2; 51% men; Study 2: n = 184; M age = 18.6 years, SD = .5; 45% men). As hypothesized in both studies, reported exercise consistently varied as a function of stage classification; those in earlier stages of readiness reported less exercise than those in later stages. Staging algorithms showed good sensitivity to detect reported exercise; however, specificity was distinctly better with the algorithm that used a specific activity criterion and immediate intention, as opposed to irregular behavior, in defining the preparation stage. Results support the validity of the staging framework for measuring motivational readiness for exercise behavior among North American adolescents.  相似文献

Abstract

The stages of motivational readiness as conceptualized by the Transtheoretical Model have been widely used among adult samples to assess readiness for adopting exercise behavior. To date, little research has been conducted using a staging framework with adolescent samples. There is a need for validation of the staging framework prior to a substantial amount of research with this age group. The current article presents two studies assessing stage and reported exercise behavior (Study 1: n = 819; M age = 15.0 years, SD = 1.2; 51 % men; Study 2: n = 184; M age = 18.6 years, SD = .5; 45 % men). As hypothesized in both studies, reported exercise consistently varied as a function of stage classification; those in earlier stages of readiness reported less exercise than those in later stages. Staging algorithms showed good sensitivity to detect reported exercise; however, specificity was distinctly better with the algorithm that used a specific activity criterion and immediate intention, as opposed to irregular behavior, in defining the preparation stage. Results support the validity of the staging framework for measuring motivational readiness for exercise behavior among North American adolescents.  相似文献

Despite the known benefits of habitual exercise in patients with heart disease, less than half of these patients exercise regularly and many of those who initiate programs fail to maintain physical activity routines over the long term. The aim of this research was to examine processes related to short- and long-term regulation of exercise to gain a clearer understanding of why people might fail to maintain intended behavioral changes. We modeled intention formation and plan formulation to investigate the distinct roles of self-efficacy and motivation (self-determination) in different phases of behavior change. Our results showed self-efficacy to be more relevant to exercise intentions and motivation to exercise planning. This research provides evidence supporting the proposition that the psychological processes related to short- and long-term regulation of behavior change differ and suggests that people might fail to continue regulating intended behavior owing to a lack of self-determined motivation.  相似文献

Although the benefits of exercise are well documented, an international problem of physical inactivity exists. More research, especially theory based, has been recommended. One promising approach for studying exercise behavior is that proposed in the Transtheoretical Model (TTM) of behavior change. This model, however, has received minimal cross-cultural attention and, relative to the current study, measurement instruments have only recently been translated into the Finnish language. The purpose of this study was to assess American and Finnish college students' exercise behaviors on the basis of TTM. Participants were American (n = 169) and Finnish (n = 168) college students who completed language-specific measures of exercise behavior, stage of change, processes of change, decisional balance, self-efficacy, and temptation. The only cultural difference observed was that the American participants rated themselves higher on barrier self-efficacy relative to the Finnish participants. Regardless of nationality orgender, participants classified by their stage of change differed on all the core constructs assessed. These results generally support the utility of TTM for understanding American and Finnish college students' exercise behavior.  相似文献

中学生锻炼行为与决策平衡的关系   总被引:1,自引:0,他引:1  
为调查中学生锻炼行为,了解锻炼阶段变化特点及其与决策平衡的关系,采用锻炼阶段变化量表、决策平衡量表对767名中学生进行测查。调查发现:被试锻炼行为阶段分布为:47.72%的中学生不锻炼(前意识和意识阶段),32.86%的中学生参与锻炼,但没有规律(准备期),19.43%的中学生参加规律性锻炼;男女生锻炼阶段变化没有显著性差异;高中生较初中生锻炼参与更少。从前意识期到准备期到维持期,利益感逐渐增加,障碍感渐小,知觉到的利益和障碍对锻炼参与有预测作用。研究提示应依据青少年锻炼阶段进行针对性认知干预。  相似文献

The majority of physical activity initiatives have been directed toward promoting cardiorespiratory fitness and general health. Far less attention has been devoted to encouraging or understanding muscular fitness-promoting behaviors. The purpose of this study was to determine if constructs from the Transtheoretical Model, a contemporary behavior change framework, could be adapted and applied to the study of muscular fitness-promoting behaviors. Participants were 429 college students who completed measures of stage of change, the behavioral and cognitive processes of change, and self-efficacy. All measures were modified to relate specifically to muscular fitness-promoting behaviors. Two direct discriminant function analyses were performed, revealing that the behavioral processes of change and self-efficacy were the major correlates of the stages of change for muscular fitness-promoting behaviors.  相似文献

通过方便抽样法选取浙江省5所高校704名大学生为研究参与者,采用横向调查设计和结构公式建模方法,检验跨理论模型各结构之间及其与身体活动之间的关系。研究结果表明,自我效能和变化阶段在变化过程与身体活动之间扮演着完全中介角色。该结果与自我效能理论和计划行为理论的预测结果相一致。变化过程可经由3条路径对身体活动产生显著的间接影响,第1条路径为变化过程→自我效能→身体活动,这条路径的中介强度最大,约占总效应的一半;第2条路径为变化过程→自我效能→变化阶段→身体活动,此路径的中介强度为28.3%;第3条路径为变化过程→变化阶段→身体活动,该路径的中介强度为19.7%。这一结果提示跨理论模型各结构之间的关系是相互关联的,共同组成了跨理论的整体模式,基于跨理论模型的干预研究不仅要考虑到模型内部各结构之间的关系,也要将整个模式作为干预的目标,只有这样才可能对跨理论模型干预措施的有效性做出正确判断。  相似文献

体育锻炼可以有效地促进身心健康,但在我国只有少数人群能够长期坚持体育锻炼。通过科学有效的健康宣导来鼓励更多的人参与体育锻炼是非常有必要的。以中国公民为研究对象,探究时间框架和未来结果的考虑对中国公民锻炼意愿的交互作用,同时也分析自我效能、时间框架和未来结果的考虑三者对中国公民锻炼意愿的交互影响。通过线上实验的方法,以不同时间框架信息为刺激物,收集了328个样本数据。研究结果显示,未来结果的考虑和自我效能都会对体育锻炼意愿产生主效应。未来结果的考虑和时间框架对体育锻炼意愿有显著的交互作用,相比于面向现在的时间框架,未来结果的考虑程度高的人接收面向未来的时间框架时更能提高体育锻炼的意愿;而未来结果的考虑程度低的人接触面向现在的时间框架信息后的体育锻炼意愿较强。此外,自我效能、时间框架和未来结果的考虑也会对中国公民锻炼意愿产生交互作用。针对自我效能高的人,如果未来结果的考虑程度较低,则接触面向现在的时间框架时,体育锻炼的意愿最强;如果未来结果的考虑程度较高,则不同的时间框架信息不会影响体育锻炼意愿。针对自我效能低的人,未来结果的考虑程度与不同的时间框架信息是否匹配则显著影响个人的体育锻炼意愿,即未来结果的考虑程度低的人接收面向现在的时间框架信息时会有较强的锻炼意愿,未来结果的考虑程度高的人面向未来的时间框架会有较强的锻炼意愿。最后,根据数据分析结果为体育锻炼健康宣导运动提出信息宣传策略,同时分析和总结本研究的不足,对未来的相关研究进行展望。  相似文献
