创业意向的构思测量、影响因素及理论模型

创业意向是指将创业者的注意力、精力和行为引向某个特定目标的一种心理状态, 它是创业行为的最好预测指标。个人背景、人格特质和外界环境等都会影响创业意向。计划行为理论和创业事件模型是公认的两个创业意向理论框架。目前将创业意向作为因变量是主流研究, 而作为自变量和控制变量则是未来研究趋势。     

Sleep hygiene behaviours: An application of the theory of planned behaviour and the investigation of perceived autonomy support,past behaviour and response inhibition

This study investigated the sleep hygiene behaviour of university students within the framework of the Theory of Planned Behaviour (TPB [Ajzen, I. (1991). The theory of planned behavior. Organizational Behavior and Human Decision Processes, 50, 179–211.]), and examined the predictive validity of additional variables including perceived autonomy support, past behaviour and response inhibition. A total of 257 undergraduate students from an Australian university were administered two online questionnaires at two time points. At time 1, participants completed the TPB questionnaire and the Go/NoGo task as a measure of response inhibition. A week later at time 2, participants completed a questionnaire measuring the performance of sleep hygiene behaviours. Multiple and hierarchical regression analyses showed that the TPB model significantly predicted intention and behaviour. Although intention and perceived behavioural control were statistically significant in predicting behaviour, past behaviour and response inhibition accounted for more variance when added to the TPB model. Subjective norm was found to be the strongest predictor of intention implying the importance of normative influences in sleep hygiene behaviours. Response inhibition was the strongest predictor of behaviour, reinforcing the argument that the performance of health protective behaviours requires self-regulatory ability. Therefore, interventions should be targeted at enhancing self-regulatory capacity.     

Predictive validity of the theory of planned behaviour: the role of questionnaire format and social desirability

The present study was designed to assess the predictive validity of a theory of planned behaviour extended to include self‐identity, in the context of health‐related food choice. Following criticism of the use of questionnaires in social cognitive research, the impact of questionnaire format (random vs structured) and social desirability on questionnaire responses was assessed. Findings indicated that intention was the principal determinant of food choice; attitude, subjective norm and self‐identity were independently predictive of intention. There was only weak evidence to suggest effects of social desirability or questionnaire format on component relationships. The present study indicates that the impact of questionnaire format and social desirability on models such as the theory of planned behaviour is minimal, and that such models are robust predictors of food choice.

Expectations of reducing fat intake: The role of perceived need within the theory of planned behaviour

Abstract

Dietary fat intake has been implicated in the causation of major diseases including coronary heart disease and cancer. Hence, current recommendatioris to improve health emphasise the reduction of fat intake (COMA, 1991). The present study investigated the effect of perceived need to reduce fat intake and past behaviour on peoples' expectations of reducing fat intake, using the framework of the Theory of Planned Behaviour (TPB) (Ajzen, 1985; 1991). The effects of estimated fat intake and body weight on perceived need to reduce were also investigated. One hundred and fifty-two adults completed a four-day weighed dietary record and completed a questionnaire based on the TPB. Perceived need to reduce fat intake, cognitive and affective components of attitude and past behaviour wm found to be significant predictors of expectation of reducing fat intake. Perceived body weight and estimated fat intake were significant predictors of perceived need to reduce fat intake. The implications of these findings for health promotion policy are discussed.     

计划行为理论述评

计划行为理论是社会心理学中最著名的态度行为关系理论,该理论认为行为意向是影响行为最直接的因素,行为意向反过来受态度、主观规范和知觉行为控制的影响。计划行为理论在国外已被广泛应用于多个行为领域的研究,并被证实能显著提高研究对行为的解释力和预测力。文章对这一理论进行了全面概述,包括理论的提出、内涵、测量方法以及理论研究的新进展,并指出了理论仍存在的问题和今后的研究方向     

How well do the theory of reasoned action and theory of planned behaviour predict intentions and attendance at screening programmes? A meta-analysis

Meta-analysis was used to quantify how well the Theories of Reasoned Action and Planned Behaviour have predicted intentions to attend screening programmes and actual attendance behaviour. Systematic literature searches identified 33 studies that were included in the review. Across the studies as a whole, attitudes had a large-sized relationship with intention, while subjective norms and perceived behavioural control (PBC) possessed medium-sized relationships with intention. Intention had a medium-sized relationship with attendance, whereas the PBC–attendance relationship was small sized. Due to heterogeneity in results between studies, moderator analyses were conducted. The moderator variables were (a) type of screening test, (b) location of recruitment, (c) screening cost and (d) invitation to screen. All moderators affected theory of planned behaviour relationships. Suggestions for future research emerging from these results include targeting attitudes to promote intention to screen, a greater use of implementation intentions in screening information and examining the credibility of different screening providers.

Predictors of smoking cessation in Taiwan: using the theory of planned behavior

This study aimed to explore the factors predicting the intention to quit smoking and the subsequent behavior 6 months later using the theory of planned behavior (TPB). Data were obtained from 145 smokers who attended a smoking cessation clinic in a community hospital. All participants completed a questionnaire which included demographic information, TPB-based items, perceived susceptibility and previous attempts to quit. The actual quitting behavior was obtained by follow-up phone calls 6 months later. The TPB constructs explained 34% of the variance in intention to quit smoking. By adding perceived susceptibility, the explained variance was significantly improved to 40%. The most important predictors were perceived behavior control and perceived susceptibility, followed by attitude. Subjective norm did not contribute to the prediction of intention. Attitude and perceived behavior control contributed to the prediction of actual quitting behavior, but intention, subjective norm and perceived susceptibility did not. Our findings support that the TPB is generally a useful framework to predict the intention to quit smoking in Taiwan. The inclusion of perceived susceptibility improved the prediction of intention. With regards to successfully quitting, attitude and perceived behavior control played more crucial roles than other TPB constructs. Smoking cessation promotion initiatives focusing on reinforcing cessation belief, enhancing a smoker’s perception of their capability to quit smoking, and persuading smokers that they can overcome cessation barriers to cessation could make subsequent interventions more effective.     

Predicting Psychologists' Intentions to Integrate Complementary and Alternative Therapies Into Their Practice

Drawing on an extended Theory of Planned Behaviour (TPB) framework, we employed a cross‐sectional design study to investigate psychologists' intentions to integrate complementary and alternative therapies (CAT) into their practice via recommending CAT to clients or referring clients to CAT practitioners. Participants were registered practicing psychologists from a range of therapeutic orientations (e.g., narrative, cognitive behavioural, psychodynamic). The psychologists were either recruited by phone, following a search of the Internet, or were contacted through their place of employment (hospitals, university counselling service). Those who agreed to participate (N = 122; n = 88 females, n = 34 males) completed a questionnaire that included standard TPB items of attitude, subjective norm, and perceived behavioural control, along with items measuring perceived risk, past behaviour, CAT knowledge, and gender. The outcome variables of interest were (a) intention to recommend CAT to clients and (b) intention to refer clients to CAT practitioners. Structural equation modelling revealed that the extended model was a good fit, explaining 69% (recommending CAT) and 51% (referring to CAT practitioners) of the variance in intentions. For both behaviours, direct paths from attitude and subjective norm to intentions were observed, with perceived risk and past behaviour influencing the TPB predictors of attitudes, subjective norm, and perceived behavioural control. The findings illustrate the role that cognitive and risk factors have on psychologists' decisions to integrate CAT into their practice. Understanding psychologists' cognitions and decisions about CAT integration forms an important basis on which to consider future changes in policy or practice.     

大学生的冒险性与创业意向的关系：感知的创业文化的调节作用

为探讨大学生的冒险性、感知的创业文化与创业意向之间的关系,采用Kogan-Wallach困境选择问卷(CDQ)、感知的创业文化问卷和大学生创业意向量表调查了996名大一至大四年级学生。结果表明:男大学生的创业目标意向和创业执行意向水平均显著高于女大学生;冒险性、感知的创业文化能够直接正向预测大学生的创业目标意向;感知的创业文化能够调节冒险性与创业目标意向之间的关系,具体来讲,对于感知的创业文化水平较高的大学生,冒险性能够积极预测创业目标意向,而对于感知的创业文化水平较低的大学生,冒险性与创业目标意向之间不存在联系。
