The relative influence of attitudes and subjective norms from childhood to adolescence: between-participant and within-participant analyses

Children and adolescents (ages 8-16) were asked to indicate their behavioral intentions, attitudes, and subjective norms for 34 behaviors. Between-participant and within-participant analyses demonstrated that attitudes and subjective norms were good predictors of behavioral intentions both singly and in combination. In addition, attitudes generally were better predictors than were subjective norms both across behaviors and across participants. Most importantly, however, there were no differences in the relative importance of attitudes and subjective norms in predicting behavioral intentions across age groups.     

An Examination of the Individual‐Difference Approach to the Role of Norms in the Theory of Reasoned Action1

The relationship between subjective norm and behavioral intentions is the weakest link of the theory of reasoned action. Numerous approaches have addressed this issue, including the assertion that the weak contribution is a result of a small number of individuals who are under normative control. The present research examines this individual‐difference approach in the domain of health behaviors. Respondents were 287 students who rated their intentions, attitudes, and subjective norms in relation to 32 health behaviors and 5 substance‐use behaviors. Regression analyses, between subjects and within subjects, demonstrated that both behaviors and people can be under attitudinal or normative control. Support for an individual‐difference approach was less conclusive when findings were examined separately for specific health behaviors.     

Distinguishing Between Perceived Behavioral Control and Self-Efficacy in the Domain of Academic Achievement Intentions and Behaviors

We examined whether perceived behavioral control (PBC) and self-efficacy (S-E) can be distinguished empirically, and whether they make different contributions to the prediction of intentions and behavior. The behavioral criterion was performance in 3 high-school examinations. Measures of attitude, subjective norm, PBC, S-E, and intention were taken before the examinations. Grade achieved served as the behavioral measure. Factor analysis of items intended to measure PBC and S-E extracted 2 factors: confidence in ability to achieve the behavioral outcome, and belief that the outcome can be influenced by own efforts. Scores on these factors were labeled S-E and perceived control, respectively. Behavior was predicted better by S-E than by intentions, and intentions were more closely related to S-E than to attitudes, subjective norms, or perceived control.     

The influence of significant others on attitudes, subjective norms and intentions regarding dietary supplement use among adolescent athletes

Dietary supplement use has increased significantly over the past decade. The use of supplements among adolescents seems to be influenced by their beliefs and attitudes. The influence of coaches, parents, and athletic trainers also may be important. The purpose of this study was (1) to determine whether attitudes are a better predictor of adolescents' intentions to use dietary supplements than are subjective norms, and (2) to assess the influence of significant others (coaches, parents, and trainers) on attitudes, subjective norms, and intentions among adolescent athletes. Adolescents (N = 1,626) who were enrolled in grades six through twelve in nine public schools completed a self-report questionnaire that measured attitudes, subjective norms, and intentions regarding dietary supplement use. Results indicated that attitudes were a better predictor of intentions to use dietary supplements than were subjective norms. It was also found that trainers had more influence on the attitudes, subjective norms, and intentions of adolescents regarding supplement use than did parents and coaches. Implications for prevention are addressed.     

The Process by Which Relative Autonomous Motivation Affects Intentional Behavior: Comparing Effects Across Dieting and Exercise Behaviors

A motivational model integrating self-deter-mination theory and the theory of planned behavior was tested in two samples for exercise and dieting behavior respectively. Relative autonomous motivation from self-determination theory was hypothesized to predict intentions to exercise or diet via the mediation of attitudes and perceived behavioral control (PBC) from the theory of planned behavior. It was also expected that attitudes and PBC would predict actual levels of exercise and dieting behavior via the mediation of intentions. Relations in the proposed model were expected to be invariant across the behaviors. Two samples of participants (N = 511) completed measures of the autonomous motives, attitudes, subjective norms, PBC, and intentions with respect to exercise and dieting behavior. Four weeks later, participants self-reported their behavior. Structural equation models supported the replicability of the proposed model in both behaviors. Findings supported the majority of the hypothesized effects in the proposed model across the two health behaviors. However, four effects were significantly different across the two behaviors: the effect of autonomous motives on intentions, subjective norms and PBC on intentions, and intentions on behavior. Findings extend knowledge of the processes by which psychological antecedents from the theories affect health behaviors integral to the maintenance of energy balance.

Studying, Practicing, and Mastering: A Test of the Model of Goal-Directed Behavior (MGB) in the Software Learning Domain

The present study tested the model of goal-directed behavior (MGB). The model proposes that behavioral intentions to perform instrumental behaviors are primarily motivated by desires to perform the acts. In turn, desires mediate the effects of attitudes, subjective norms, perceived control, and anticipated emotions on intentions. Construct validity for MGB variables is assessed, and the predictive utility of the MGB is compared with that of the theory of planned behavior (TPB). College students ( N = 102) provided measures for MGB and TPB variables while participating in a training program to use statistical software. We focused on two goal-related instrumental behaviors: studying handbooks and practicing with the package. The results show that the MGB accounts for a greater proportion of variance in intentions and instrumental behaviors than does TPB. Although desires mediate most of the effects of other predictors on intentions to perform the instrumental behaviors, it is proposed that when the behavior is normatively relevant, or when self-efficacy appraisals play a major role, subjective norms and perceived behavioral control may directly affect intentions.     

The Importance of Attitudes in the Prediction of College Students' Intentions to Drink

Fishbein's (1967, 1980) theory of reasoned action was used to test the relative importance of attitudes and subjective norms in predicting undergraduate students' intentions to perform 3 different types of social drinking actions: avoiding drinking, drinking enough to get a slight buzz, and drinking enough to get drunk. A multiple regression paradigm was used to determine the relative effectiveness of attitudes and subjective norms in predicting intentions to perform each of the 3 drinking behaviors. Although attitudes were consistently found to be better predictors of intentions than were subjective norms, the strength of the attitude-intention relation varied widely across the 3 actions. In particular, the attitude-intention correlation was strongest for "drinking enough to get drunk." Findings also suggest that subjective norms, previous behavior, and perceived behavioral control are not important variables for predicting this behavior.     

Behavioral Goals for a Diverse Organization: The Effects of Attitudes, Social Norms, and Racial Identity for Asian Americans and Whites

This research identified 5 behaviors that may enhance the effectiveness of a diverse organization and used Fishbein and Ajzen's (1975) theory of reasoned action to identify predictors of these behaviors. Results from samples of White and Asian undergraduate students from 2 universities generally supported the Fishbein and Ajzen model. Attitudes and subjective norms were significant predictors of behavioral intentions when gender, race, and social desirability bias were controlled. Racial identity also had a significant, positive effect on attitudes toward diversity-related behaviors among the Asian American students, but no significant effect among Whites. These results supported our reasoning that members of historically excluded racial groups with strong racial identities will be most likely to welcome organizational attempts to become more pluralistic because pluralism means that their valued identities will be respected rather than repressed.     

Development and Psychometric Evaluation of the Social Justice Scale (SJS)

The study describes the development of the Social Justice Scale (SJS). Practitioners, educators, students, and other members of the community differ on their attitudes and values regarding social justice. It is important to assess, not only individuals' attitudes and values around social values, but also other constructs that might be related to social justice behaviors. The implication of Ajzen in Organizational Behavior and Human Decision Processes 50:179-211, (1991) theory of planned behavior suggests that attitudes, perceived behavioral control, and social norms predict intentions, which then lead to behaviors. A scale was designed to measure social justice-related values, attitudes, perceived behavioral control, subjective norms, and intentions based on a four-factor conception of Ajzen's theory. Confirmatory factor analysis and analyses for reliability and validity were used to test the properties of the scale.     

Behavioral reasoning theory: Identifying new linkages underlying intentions and behavior

This study developed and tested a new theory of behavior, entitled behavioral reasoning theory. The theory proposes that reasons serve as important linkages between beliefs, global motives (e.g., attitudes, subjective norms, and perceived control), intentions, and behavior. An underlying theoretical assumption in this framework states that reasons impact global motives and intentions, because they help individuals justify and defend their actions. Four studies were conducted to test theoretical propositions. Using confirmatory factor analyses and structural equation modeling, Study 1 demonstrated that reasons (for and against the behavior) were differentiated from global motives and independently predicted intentions and behavior. Through orthogonal manipulation, Study 2 showed that global motives and reasons influenced intentions. Study 3 found that reasons contributed to the prediction of intentions beyond traditional belief concepts and that belief concepts predicted reasons. Finally, Study 4 experimentally demonstrated that traditional belief concepts (including interaction terms) and reasons influenced global motives and intentions. In all, while traditional concepts explained significant amounts of variance, the overall results suggest that reason concepts explain meaningful amounts of additional variance and, thus, also need to be considered.     

Factors Influencing Gay Men's Attitudes,Subjective Norms,and Intentions With Respect to Performing Sexual Behaviors1

In a recent paper (Fishbein et al., 1992) gay men's attitudes and subjective norms were found to be accurate predictors of their intentions to perform a variety of sexual behaviors. In addition, the relative importance of norms as determinants of intention was found to be greater in Seattle (a city with a well organized gay community) than in Albany (a city in which the gay community is not well organized). The purpose of the present study was to investigate the extent to which the men's attitudes, subjective norms, and intentions were influenced by a number of situational and individual difference variables. Three hundred and fourteen self-identified gay or bisexual men from Seattle (134), Denver (78), and Albany (102) completed a questionnaire specifically designed for this study. As expected, type of partner and type of sexual activity significantly influenced attitudes, perceived norms, and intentions. In addition, these dependent variables were also influenced, in part, by city of residence, age, and perceived risk of HIV infection. The findings provide additional justification for developing different interventions for gay men in different cities, age, and perceived risk groups.     

Mental Health Services Use Intentions Among Canadian Military Recruits

Identifying the factors associated with mental health services use (MHSU) is an important step in developing strategies to improve services access and delivery. The aims of the present study were to (a) identify personality and individual difference characteristics associated with MHSU intentions within the framework of the Theory of Planned Behavior (TPB) and (b) explore complex relationships that might exist between these characteristics and determinants of MHSU intentions identified in TPB, including attitudes, subjective norms, and perceived behavioral control. Data for 244 Canadian Armed Forces recruits who completed a MHSU questionnaire following mental health training were linked to personality data collected earlier. Multivariate analyses showed that the relationship between agreeableness and MHSU intentions was mediated by instrumental attitudes and subjective norms. The relationship between hardiness and MHSU intentions was mediated by subjective norms and self-efficacy. Findings suggest it may be worthwhile to consider mental health education initiatives to improve MHSU.     

The Effects of Source Credibility and Message Framing on Exercise Intentions,Behaviors, and Attitudes: An Integration of the Elaboration Likelihood Model and Prospect Theory1

This study examined the influence of source credibility and message framing on promoting physical exercise in university students. Participants were randomly assigned to reading a positively or negatively framed communication that was attributed to either a credible or a noncredible source. Exercise intentions and attitudes were measured immediately following the delivery of the communication and following a 2‐week delay. Exercise behavior was also measured following the delay. There were Source Frame interactions for the exercise intentions, exercise behaviors, and cognitive response/elaboration measures such that participants receiving a positively framed communication from a credible source elaborated more and reported more positive exercise intentions and behaviors than participants in the other conditions. The results of the present investigation indicate that it might be beneficial for health professionals to provide exercise‐related information stressing the benefits of participating in exercise, rather than the traditional fear appeals, to motivate clients to engage in regular physical exercise. Implications for future research are discussed.     

The Correlates of Antinuclear Activism: Attitudes, Subjective Norms, and Efficacy

Ajzen's (1988) theory of planned behavior was modified and used to examine antinuclear behavior. Subjects completed a questionnaire measuring their antinuclear attitudes, their perceptions of support for taking antinuclear action, and their perceptions of efficacy in this arena. Then, an antinuclear behavioral intentions questionnaire was presented, as well as several opportunities to engage in various antinuclear actions. Regression analyses indicated that Ajzen's model was supported to the extent that attitude emerged as a significant predictor of antinuclear intentions and behaviors. Subjective norms and efficacy were not significant predictors of either intentions or behaviors. Models incorporating behavior-specific attitude measures accounted for more variance than did models using more general attitude measures toward nuclear war/weapons.     

Smell and Taste Classification of the Same Stimuli

Much literature has suggested that people who are discriminated against or are in collectivist cultures are particularly susceptible to the social consequences of society. In the present study, the authors conducted 3 experiments to test how this factor influences attitudinal versus normative control over behaviors. First, they measured males’ and females’ attitudes, subjective norms, and behavioral intentions with respect to a large number of behaviors. Although between-participants analyses were mostly uninformative, within-participants analyses uncovered strong evidence that behaviors are more under attitudinal control for females than for males. Similar analyses in a crosscultural experiment involving participants from the United States, the United Kingdom, China, and Mexico support the hypothesis that behaviors are more under attitudinal control for collectivists than for individualists. Finally, experimental data collected in the United States and Saudi Arabia further support this conclusion. Taken together, the findings suggest that although social consequences are both “social” and “consequences,” the latter is more important than the former.     

The importance of subjective norms for people who care what others think of them

Using the framework of the Theory of Planned Behaviour (TPB), this study examined whether the extent to which people are concerned with others’ approval of them moderates the subjective norms–intentions relationship in the context of exercise. The participants were 325 undergraduate students who completed a questionnaire assessing the TPB constructs (subjective norms, attitudes, perceived behavioural control, intentions) and the Brief Fear of Negative Evaluation Scale. The results of hierarchical regression analyses indicated that subjective norms were a significant predictor of intentions to exercise only for people highly concerned with receiving disapproval from others (i.e., high fear of negative evaluation) and not for people low on this trait.     

Physically active students' intentions and self-efficacy towards healthy eating

This study investigated intentions and self-efficacy of physically active university students towards healthy eating. The application of Planned Behavior theory has shown that attitudes, intention, perceived behavioral control, and subjective norms play an important role in shaping people's behavior. 96 students, who participated in physical activities, voluntarily completed the Questionnaire for the Planned Behavior Model and the Health Behavior Questionnaire. The former examines attitudes, intentions, perceived behavioral control, and the lately added attitude strength, and role identity towards the behavior factors. The latter assesses one's efficacy expectations towards healthy eating. The regression showed strong associations between the examined variables, signifying that attitudes, perceived behavioral control, and role identity could account for one's intention towards healthy eating behaviors. On the other hand, one's self-efficacy for healthy eating could be explained from the attitudes, intention, perceived behavioral control, and attitude strength held. Overall, systematic participation in physical activities appeared to be accompanied with a relatively healthier diet, while self-efficacy had a significant association with maintaining the healthy eating behaviors. Possible interpretations, limitations, and implications for health professionals are discussed.     

Individual Differences in the Predictions of Behavioral Intentions

Abstract

We examined individual differences in the formation of behavioral intentions by American female students. Within the frameworks of the Fishbein-Ajzen and Triandis models of behavioral intentions, we measured the relative emphasis given to intention predictors for 40 behavioral intentions and examined how this emphasis was related to authoritarianism. In addition, empirical evidence was sought for the conceptual distinction between a personal norm (internalized norm) and a subjective norm (perceptions of significant other' opinions concerning a given action). Relative to low authoritarians, high authoritarians took subjective norms less into account, placed greater emphasis on personal norms, and emphasized less the consequences of action in forming behavioral intentions. The results suggest that subjective and personal norms can be distinguished empirically.     

A Comparison of Health Behavior Constructs: Social Psychological Predictors of AIDS-Preventive Behavioral Intentions

The present study focused on predicting AIDS-preventive behavioral intentions (i. e., intentions to discuss AIDS-related information and to use condoms) from constructs taken from the health belief model, the theory of reasoned action/planned behavior, and social cognitive theory. Questionnaire data were collected from 124 undergraduates using scales from previously published work as well as some new measures designed for this study. Perceived behavioral control, perceived risk, attitudes, self-efficacy, subjective norms, negative expected outcomes, and perceived severity of HIV infection were correlated with at least one intention measure; but regression analyses showed that perceived behavioral control was the strongest independent predictor of condom use intentions and of intentions to discuss AIDS information with a partner. Implications for theory and application are discussed.
