The role of risk perception in explaining parental sunscreen use

Objective: This study assessed: (1) whether risk perceptions about skin cancer were related to parent's use of sunscreen on their children; (2) which combination of assessments susceptibility and severity best explain parental sunscreen protection behaviours and (3) whether risk perceptions influence behaviour directly through intentions or through attitudes, subjective norms and self-efficacy. Design: Two longitudinal studies assessed sunscreen protection behaviours of parents for their toddlers (N?=?391) and young children (N?=?436). Main outcome measure: Parent's use of sunscreen on their children. Results: Risk perceptions correlated with future sunscreen protection behaviours of parents but were lower than those of attitude, social influence and self-efficacy. Treating susceptibility and severity as an additive function resulted in the best model fit. Risk perceptions were related with future intention and future sunscreen protection behaviour, but the effects were mediated through attitude, social influence and self-efficacy. Conclusions: Our path analyses suggest treating susceptibility and severity as an additive function. A multiplicative model without main effects - although often used - had the poorest fit. Risk perceptions influence behaviour by influencing attitudinal and self-efficacy beliefs. Addressing risk perceptions in health communication programs is relevant when the purpose is to increase awareness and to influence attitudes and self-efficacy.

Predicting parental sunscreen use: Disentangling the role of action planning in the intention–behavior relationship

Structural equation modeling was used to examine antecedents of parental sunscreen use (N = 436) in a longitudinal design. The influence of a volitional planning cognition was assessed in several path models, investigating potential mediation and moderation of the intention–behavior relationship. Premotivational and motivational variables accounted for 55.1% of the variance in intention to use sunscreen. Intention emerged as the most powerful predictor of behavior, followed by action planning and self-efficacy expectations, together explaining 35.4% of parental sunscreen use after five months. Strong support was found for both mediating and moderating influences of action planning on the intention–behavior relationship. Action planning also partially mediated the impact of self-efficacy on behavior. The results support theoretical considerations to add postintentional cognitions to current health behavior models. Although action planning is an important component in the transition from intention to behavior, the impact of intention and of other premotivational and motivational variables should not be overlooked when developing health educational interventions.     

Mediation of a middle school skin cancer prevention program.

This study tested potential mediators of a school-based skin cancer prevention intervention for middle school children (6th-8th grades; N = 1,788). Ten variables were tested on 4 criteria to establish mediation, including (a) intervention related to outcome, (b) intervention related to mediators, (c) mediators related to outcome, and (d) mediated effect statistically significant. Sun-safe behaviors (e.g., sunscreen use) and potential mediators were measured with a self-report questionnaire. All criteria were met for Barriers--Sunscreen, Perceived Self-Efficacy, and Knowledge when the mediators were tested separately. In multiple mediator analyses, barriers to sunscreen use and self-efficacy satisfied Criteria 1-3 but were not statistically significant (Criterion 4). Barriers to sunscreen use, perceived self-efficacy for sun-safe behavior, and knowledge may serve as mediators.

Differentiating Among Motives for Norm Conformity

Two studies investigated why individuals conform to social norms. The authors propose that individuals conform to social norms to satisfy 3 general motives: accuracy, self-related, and other-related. Building on previous behavior prediction models, Study 1 found that measures of norms that identify specific motivational goals predicted behavior and intention better than did standard measures of social norms that consider only other-related motives for conformity. Study 2 investigated whether variations in the situational context are associated with alterations in motivational reasons for conforming to norms. Results indicated that one's motives for conforming to norms are sensitive to situational constraints. The findings from both studies suggest that, when predicting normative influences on behavior, research should address multiple motives underlying conformity with social norms.     

Today I'll use a condom, but who knows about tomorrow: a daily process study of variability in predictors of condom use

OBJECTIVE: Most models of health behavior change applied to condom use behavior have focused on individual differences in theoretical constructs to explain condom use or nonuse, while ignoring the possibility that day-to-day within-person changes in these constructs may contribute to understanding behavior. The goal of the present study was to investigate day-to-day variability in condom use attitudes, self-efficacy, and behavioral intentions and assess the utility of this variability in predicting the likelihood of condom use each day. DESIGN: A 30-day Web-based structured daily diary was used to collect daily reports of sexual behaviors and data on theoretical predictors of condom use behavior from sexually active college students (N = 116). MAIN OUTCOME MEASURES: The authors investigated whether condom use attitudes, self-efficacy, and behavioral intentions vary day to day; whether this within-person variability predicts condom use behavior; and whether negative affective states explain this variability. RESULTS AND CONCLUSIONS: Within-person variability was found for each of the constructs. Within-person day-to-day changes in behavioral intentions and attitudes predicted the instances in which an individual used a condom and daily negative affect partially explained within-person day-to-day changes in behavioral intentions and self-efficacy. Implications for models of health behavior change and for behavior change interventions are discussed.     

Global positive expectancies of the self and adolescents' substance use avoidance: testing a social influence mediational model

Grounded in theories of global positive expectancies and social influences of behavior, this investigation posited a model in which global positive expectancies are related to substance use as mediated by attitudes, subjective norms, self-efficacy, and intentions. Using a cohort sample (n = 525), structural equation modeling was employed to test the hypothesized predictions of future substance use. The findings suggest that, relative to adolescents with lower global positive expectancies, adolescents with higher global positive expectancies use substances less frequently over time because of their protective attitudinal and control-oriented perceptions towards that behavior. Additionally, results from the current investigation also extend prior findings on the factor structure of global positive expectancies, suggesting these expectancies can be viewed as a second-order factor representing optimism and two components of hope-agency and pathways.     

Individual- and perceived contextual-level antecedents of individual technical information inquiry in organizations

The authors conducted an empirical study in research and development centers and research-oriented commercial companies in Singapore to test a model for understanding individuals' technical information inquiry behavior in organization settings. Individual-level antecedents (learning orientation, risk-taking propensity, and self-efficacy) and perceived contextual-level antecedents (management support, relationship quality, organizational norms favoring technical information inquiry, and accessibility of the information source) were theorized to affect one's evaluation of the potential benefits and costs in making technical information inquiries. The results showed that the perceived norms favoring technical information inquiry affected the willingness of individuals to make technical information inquiries through the mediating variable, expectancy value. In addition, compared with individual-level variables, perceived contextual-level variables explained slightly more variance in the willingness to make technical information inquiries. Theoretical and practical implications are discussed.     

The Impact of Social Influences in the Context of Attitude,Self-Efficacy,Intention, and Previous Behavior as Predictors of Smoking Onset1

Three different constructs for measuring social influence were utilized in the present study to explain adolescents' present and future smoking behavior at 6 (T2), 12 (T3), and 18 months (T4) after the first test. Social influence was assessed by measuring the social norms, perceived smoking behavior, and direct pressure. The impact of the social influence constructs was also assessed in the context of broader models, including attitudes and self-efficacy expectations, intention, and previous behavior. The three social influence measures correlated significantly with intention and behavior. Stepwise regression analyses showed that perceived behavior and pressure made significant contributions, after entering social norms, in explaining actual and future adolescent smoking behavior. Adding attitudes and self-efficacy increased the predictive power of the model significantly. In agreement with the theory of Fishbein & Ajzen (1975), intention was the most powerful predictor in explaining present and future smoking behavior. Attitudes, self-efficacy, and the social influences also made small unique contributions improving the explanatory power by approximately 5%. Previous behavior, however, had a substantial unique contribution in predicting future behavior after attitudes, social influences, self-efficacy, and intention were entered in the equations. Since social influences may exert their impact via different routes, it is recommended that smoking prevention programs discuss not only overt pressures such as direct pressure from peers, parents, and media, but also address the more covert social pressures such as modeling and the adolescents' ability to cope with these covert influences. Furthermore, norms on nonsmoking should be made explicit.     

Job-search persistence during unemployment: a 10-wave longitudinal study

Dynamic predictors of job-search intensity over time are examined in a large 10-wave longitudinal study of unemployed individuals. Two sets of variables relevant to the examination of job search from a dynamic, self-regulatory perspective--core self-evaluations (T. A. Judge, A. Erez, & J. E. Bono, 1998) and the theory of planned behavior (I. Ajzen, 1991)--were used to guide our examination. Results suggest core self-evaluation is related to average levels of job-search intensity over time. Job-search intentions mediated the relationship between subjective norms and job-search self-efficacy in the prediction of job-search intensity in the following 2 weeks. Both Time 1 and cumulative job-search intensity predict reemployment. This repeated-measures study contributes to research on job search that has been primarily cross-sectional or included few time waves.     

Improving condom use intentions and behavior by changing perceived partner norms: an evaluation of condom promotion videos for college students.

OBJECTIVE: To examine the effectiveness of 2 condom promotion videotapes on self-efficacy, intentions, and behavior. DESIGN: Two hundred twenty college students completed social-cognitive and behavioral measures and were then randomly assigned to receive one of two 30-min condom promotion videotapes (male or female student presenters) or to a wait-list control condition. Participants who watched 1 of the videotapes completed immediate posttest measures, and 85% of participants completed a 4-month follow-up. MAIN OUTCOME MEASURES: Self-efficacy for condom use, intentions to use condoms, use of condom during last sex, and consistent condom use over the last month. RESULTS: Participants who received either video reported greater self-efficacy to refuse to have unprotected sex and intentions than controls at follow-up. Individuals who received either video were more likely than controls to report using a condom during last sex with a regular partner, and those who watched the female presenter were more likely to report consistent condom use. CONCLUSION: Participants benefited in terms of self-efficacy and intentions from receiving either video, but both men and women benefited more in terms of condom use behavior from receiving the female video. Future research is needed to determine whether opposite-sex speaker videos could be beneficial with a larger (and more sexually active) sample and whether these effects are maintained over time.     

Organizational Spontaneity in Context

This article suggests that our understanding of extra-role behaviors such as organiza- tional spontaneity may be enhanced by considering the context in which these behaviors occur. The context may provide individuals with either opportunities to engage in forms of organizational spontaneity or constraints against performing these behaviors. Proposed contextual influences at the individual level of analysis include skill level, self-efficacy, role definitions, interpersonal relationships, and help-seek- ing behavior. Proposed contextual influences at the group level of analysis are group norms, interdependence, and goals. Proposed contextual influences at the organiza- tional level of analysis include organizational structure, culture, company policies, and reward systems. Lastly, proposed contextual influences at the interorganizational level of analysis include the isomorphic forces that result in organizations becoming more similar to each other over time. Implications of this analysis for future theorizing and research are discussed.     

Self-Efficacy as a Mediator of the Relationship Between Causal Attributions and Exercise Behavior

The primary purposes of this study were to examine whether the attribution–intention link was mediated by self-efficacy and whether the attribution–behavior link was mediated by self-efficacy. As a secondary purpose, we examined whether the attribution–behavior link was mediated by exercise intentions. These relationships were tested prospectively at multiple time points. Participants were 260 adult exercisers ( M age=32 years) enrolled in 12 weeks of structured exercise classes. Social cognitive measures were assessed at early and midprogram; attendance was tracked for the first and second half of the program. Hierarchical multiple regression procedures indicated support for self-efficacy as a mediator of the relationship between attributions and behavior. Secondary analyses revealed support for intention as a mediator of the attribution–behavior relationship. Finally, additive relationships in support of social cognitive theory also were detected. The attribution/self-efficacy/behavior link is important for adherence interventions and should be investigated further in both asymptomatic and symptomatic populations.     

The Effects of Self-Efficacy on Behavior in Escalation Situations

Two experiments were conducted to investigate the hypothesis that perceptions of self-efficacy influence, in various ways, behavior in escalation situations. Self-efficacy beliefs for finding oil were measured for 527 petroleum geologists as they decided, at increasing levels of negative feedback in the form of dry wells, whether to persist with an unproductive venture in petroleum exploration. Experiment 1 employed a within-subject design and found a significant main effect of both negative feedback and initial self-efficacy. Differences in intentions to escalate between low and high self-efficacy individuals were apparent at all levels of negative feedback. No moderating effect of self-efficacy, however, was discernible. Experiment 2 employed a between-subjects design and multiple regression analysis. Like Experiment 1, Experiment 2 revealed a significant main effect of negative feedback and initial self-efficacy. Post-feedback self-efficacy was found to mediate the effects of negative feedback on the escalation tendency. Implications of these results for the self-efficacy and escalation literatures are discussed.     

Factors affecting behaviors that address HIV risk among senior secondary school pupils in South Africa.

The purpose of this study was to identify factors affecting HIV risk reduction among senior secondary school pupils in South Africa. The sample included 460 Grade 12, Secondary School pupils whose ages ranged from 16 to 30 years (M = 19.7 yr., SD = 2.5) and who were chosen at random from the total Grade 12 population throughout one region in the Northern Province of South Africa. Measures were of sexual behavior and condom use, knowledge about correct condom use, intention of condom use, behavioral norms, attitudes, normative beliefs, and subjective norms about condoms, HIV/AIDS vulnerability (likelihood to get it) and severity of the illness in the country, and condom use self-efficacy. Bivariate analysis gave positive significant relations among normative beliefs, subjective norms, and attitudes towards condom use as well as HIV/AIDS vulnerability and HIV risk behavior. Regression analysis indicated that for boys, younger age at first vaginal intercourse, less intention for condom use, and HIV/AIDS vulnerability were predictive for HIV/AIDS risk behavior and explained 39% of the variance. It is suggested that these predictors should be included in intervention programs for HIV prevention.     

Can language prime culture in Hispanics? The differential impact of self‐construals in predicting intention to use a condom

The highly influential theory of planned behavior suggests that norms and attitudes predict an important antecedent of behavior: intention. Cross-cultural research suggests that culturally influenced self-construals can be primed and differentially affect behaviors that are influenced by norms and attitudes. The purpose of this experiment was twofold: (1) To investigate whether language functions as a prime for culture in Hispanics, and (2) if so, if norms and attitudes differentially predict condom use intention. Fluent English-Spanish bilingual participants (N = 145) of Mexican descent were randomly assigned to answer questionnaires in English and Spanish. Subjective norms and private evaluations towards condom use were assessed and their relative strength in predicting condom use intention was evaluated. Results suggest that language can prime culture and affect the relative accessibility of culture-relevant norms and self-construals in Hispanics. Moreover, consistent with our expectations, norms and attitudes differentially predicted condom use intention.     

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.     

How did it work? An examination of the mechanisms through which an intervention for the unemployed promoted job-search behavior

Conducted process analysis of treatment mediation effects (Judd & Kenney, 1981) on longitudinal data from a large randomized field experiment with 928 recently unemployed persons. The experimental treatment included an intervention that succeeded in promoting quality reemployment outcomes, as described in earlier reports (Caplan et al., 1989; Vinokur et al., 1991). Using Ajzen's theory of planned behavior (Ajzen, 1985, 1988), the analyses examined the mediating effects of job-search self-efficacy, attitude, norms, and intention on job-search behavior. The results provided substantial support for the theory of planned behavior and demonstrated the mediational role of job-search self-efficacy. For both 1- and 4-month posttests, job-search self-efficacy was shown to mediate the effects of the intervention through its direct effects on job-search intention and on short term job-search behavior, as well as through its indirect effects on subjective norms and attitude. However, in the longer term 4-month posttest, exposure to the intervention had a direct effect on job-search behavior. This long-term direct effect of the intervention was hypothesized to reflect the influence of inoculation against setbacks which is essential for sustaining the long-term behavioral efforts involved in job seeking.     

Self-conscious emotions and self-regulation in the promotion of condom use

Two prospective studies examined the self-regulatory role of anticipated negative self-conscious emotions (ANSCE) in the theory of planned behavior. In Study 1, 147 undergraduates reported condom attitudes, perceived norms, self-efficacy, ANSCE (shame and guilt) should they not use condoms, and intentions to use condoms during the coming 6 weeks. At a 6-week follow-up, ANSCE predicted condom use intentions and behavior and partially mediated the effect of attitudes and norms on both. Study 2 experimentally tested the social nature of self-consciousness in ANSCE; 61 female undergraduates read a scenario priming the private-self or social-self or were assigned to a no-scenario control. They reported condom attitudes, perceived control, ANSCE, condom use intentions, and a 6-week follow-up. ANSCE again predicted condom use intentions. A test of moderated mediation indicated that ANSCE influenced condom intentions more in the social-self condition than in the control condition. Implications of these findings are discussed.
