The Theory of Planned Behaviour (TPB) has received considerable attention in the literature. The present study is a quantitative integration and review of that research. From a database of 185 independent studies published up to the end of 1997, the TPB accounted for 27% and 39% of the variance in behaviour and intention, respectively. The perceived behavioural control (PBC) construct accounted for significant amounts of variance in intention and behaviour, independent of theory of reasoned action variables. When behaviour measures were self-reports, the TPB accounted for 11% more of the variance in behaviour than when behaviour measures were objective or observed (R2s = .31 and .21, respectively). Attitude, subjective norm and PBC account for significantly more of the variance in individuals' desires than intentions or self-predictions, but intentions and self-predictions were better predictors of behaviour. The subjective norm construct is generally found to be a weak predictor of intentions. This is partly attributable to a combination of poor measurement and the need for expansion of the normative component. The discussion focuses on ways in which current TPB research can be taken forward in the light of the present review.

Are Americans more individualistic and less collectivistic than members of other groups? The authors summarize plausible psychological implications of individualism-collectivism (IND-COL), meta-analyze cross-national and within-United States IND-COL differences, and review evidence for effects of IND-COL on self-concept, well-being, cognition, and relationality. European Americans were found to be both more individualistic-valuing personal independence more-and less collectivistic-feeling duty to in-groups less-than others. However, European Americans were not more individualistic than African Americans, or Latinos, and not less collectivistic than Japanese or Koreans. Among Asians, only Chinese showed large effects, being both less individualistic and more collectivistic. Moderate IND-COL effects were found on self-concept and relationality, and large effects were found on attribution and cognitive style.

Rethinking individualism and collectivism: evaluation of theoretical assumptions and meta-analyses.

This survey of attitude theory and research published between 1996 and 1999 covers the conceptualization of attitude, attitude formation and activation, attitude structure and function, and the attitude-behavior relation. Research regarding the expectancy-value model of attitude is considered, as are the roles of accessible beliefs and affective versus cognitive processes in the formation of attitudes. The survey reviews research on attitude strength and its antecedents and consequences, and covers progress made on the assessment of attitudinal ambivalence and its effects. Also considered is research on automatic attitude activation, attitude functions, and the relation of attitudes to broader values. A large number of studies dealt with the relation between attitudes and behavior. Research revealing additional moderators of this relation is reviewed, as are theory and research on the link between intentions and actions. Most work in this context was devoted to issues raised by the theories of reasoned action and planned behavior. The present review highlights the nature of perceived behavioral control, the relative importance of attitudes and subjective norms, the utility of adding more predictors, and the roles of prior behavior and habit.

On the bases of Greenwald and Pratkanis's (1984) distinction between private and collective aspects of the self and on Triandis's (1989) theory about individualistic and collectivistic cultures, 2 competing theories concerning the organization of self-cognitions were proposed. Findings from 2 experi

Intentions to perform most behaviors are more controlled by attitudes than by subjective norms. Yet subjective norms typically account for a significant, albeit small, proportion of unique variance in intentions. To explore the hypothesis that this effect can be explained largely by individual differences in the degree to which some people are apt to be more under normative control, subjects were asked to indicate their intentions, attitudes, and subjective norms toward performing 30 behaviors. Between-subjects and within-subjects analyses were performed. The within-subjects analyses revealed important differences in whether subjects are under attitudinal or normative control across the behaviors. Further, when "normatively controlled" subjects were excluded from the sample, the significant effects of subjective norms on intentions that were obtained in previous between-subjects analyses were eliminated, and the attitudinal effects were augmented. Finally, this individual difference was associated with th...

Four studies were performed to test whether Ajzen's (1988, 1991) concept of perceived behavioural control is really an amalgamation of two variables, which we term ‘perceived control’ and ‘perceived difficulty’. Perceived control refers to the extent to which people consider the performance of a behaviour to be under their voluntary control. Perceived difficulty refers to whether people consider a behaviour to be easy or difficult to perform, Findings from Studies 1 to 4 demonstrate that it is possible to perform manipulations that affect perceived control more than perceived difficulty, or that affect perceived difficulty more than perceived control. Studies 2–4 used a variety of paradigms to show that people distinguish between beliefs that are presumed to underlie perceived control and perceived difficulty. Finally, we performed a meta-analysis in Study 5 to determine whether perceived control or perceived difficulty is more important for predicting behavioural intentions and behaviours. Taken together, the findings support the distinction between perceived control and perceived difficulty, and also suggest that perceived difficulty is a better predictor of most behavioural intentions and behaviours than is perceived control.

Evidence that perceived behavioural control is a multidimensional construct: Perceived control and perceived difficulty

The (latest) crisis in confidence in social psychology has generated much heated discussion about the importance of replication, including how it should be carried out as well as interpreted by scholars in the field For example, what does it mean if a replication attempt "fails"-does it mean that the original results, or the theory that predicted them, have been falsified? And how should "failed" replications affect our belief in the validity of the original research? In this paper, we consider the replication debate from a historical and philosophical perspective, and provide a conceptual analysis of both replication and falsification as they pertain to this important discussion Along the way, we highlight the importance of auxiliary assumptions (for both testing theories and attempting replications), and introduce a Bayesian framework for assessing "failed" replications in terms of how they should affect our confidence in original findings
