Predicting physical activity intention and behaviour among children in a longitudinal sample.

We examined predictors of leisure-time physical activity intention and behaviour in children, and the potential direct and moderating effects of gender and ethnicity. Participants were 364 (230 Asian; 134 Caucasian) 9-11-year-old children who completed measures of the theory of planned behaviour (TPB) and physical activity behaviour (Physical Activity Questionnaire for Children) across three, 3-month intervals (i.e., two prediction time-periods) in Canada. The TPB explained 35-50% of the variance in physical activity behaviour and 74-76% of the variance in intention using structural equation modelling. An autoregressive longitudinal path model showed that the TPB predicted changes in physical activity and physical activity predicted changes in TPB constructs (p<.05). Overall, intention and perceived behavioural control were significant (p<.05) contributors to the direct prediction of behaviour and subjective norm and perceived behavioural control were significant (p<.05) predictors of intention. Gender did not show a robust relationship with physical activity or intention, but the effect of ethnicity on physical activity was mediated through perceived behavioural control (Asians less active than Caucasians). Finally, gender and ethnicity did not moderate TPB and physical activity relations (p<.05). These data suggest that childhood may be a formative stage for the development of physical activity cognitions and that promoting physical activity in children may require normative and control-based intervention.

Knowledge, attitudes, and behavioral intentions in relation to the early detection of colorectal cancer in the United Kingdom.

BACKGROUND: Colorectal cancer (CRC) mortality is high. Understanding the social, psychological, and cognitive predictors of early detection practices such as screening may help improve CRC outcomes. This study examined knowledge of CRC and the relationship between knowledge, attitudes to cancer, and intentions to engage in early detection behaviors for CRC in a national representative population sample. METHOD: An interview-based survey was carried out in a British population sample of adults ages 16 to 74 years (n = 1637), assessing knowledge, attitudes, and intention with regard to colorectal cancer. RESULTS: Knowledge levels were very low; 58% (n = 995) of respondents could not list any colorectal cancer risk factors and 24% (n = 393) were unable to identify any warning signs for cancer. Knowledge was lower among men (chi(2)[2] = 52.8, P < 0.0001), younger respondents (chi(2)[10] = 79.9, P <.0001), and those with less education (chi(2)[4] = 73.9, P < 0.0001). Attitudes to cancer were more negative among women (chi(2) [2] = 7.4, P = 0.025), younger participants (chi(2)[10] = 22.4, P = 0.013), and those with less education (chi(2) [4] = 75.0, P < 0.0001). Low knowledge was associated with negative attitudes (P < 0.0001) and both factors were associated with lower intentions to participate in colorectal cancer screening (P < 0.0001). Multivariate analysis indicated that attitudes partially mediated the effect of knowledge on screening intentions. CONCLUSIONS: Increasing knowledge may reduce negative public perceptions of cancer which may impact positively on intentions to participate in screening.

The intention of adolescents to carry a knife or a gun: a study of low-income African-American adolescents.

PURPOSE: To examine whether African-American inner-city adolescents are independently motivated by a fear of victimization or by delinquency to carry a knife or gun. METHODS: A household sample of 130 female and 93 male African-American adolescents, aged 13-19 years old, were queried about their fear of victimization, history of delinquency, and intention to carry a knife or a gun in the next 3 months. RESULTS: A high intention to carry a knife was reported by 27% of the males and 35% of the females. A high intention to carry a gun was reported by 25% of the males and 9% of the females. The intention to carry a knife was independently associated with a history of delinquency in females (odds ratio [OR] = 3.0; 95% confidence interval [CI] = 1.4-6.2) and males (OR = 4.7; 95% CI = 1.7-13.3). It was not associated with a fear of victimization. The intention to carry a gun was independently associated with fear of victimization in females (OR = 4.5; 95% CI = 1.1-17.7) and males (OR = 3.3; 95% CI = 1.1-9.9). It was also independently associated with a history of delinquency in females (OR = 4.1; 95% CI = 1.1-16.3) and males (OR = 11.7; 95% CI = 3.1-44.7). CONCLUSIONS: Delinquency may play a role in motivating inner-city African-American adolescents to carry a knife, whereas both delinquency and fear of victimization may influence adolescents' motivation to carry a gun.

Correlates of attitudes toward homosexuality and intention to care for homosexual people among psychiatric nurses in southern Taiwan.

This study examined the association between attitudes toward homosexual individuals and intention to provide care and demographic and occupational factors, sexual orientation, knowledge about homosexuality, and experiences of contact with homosexual people among psychiatric nurses in southern Taiwan. In total, 133 psychiatric nurses from a medical center, three regional teaching hospitals, and one psychiatric hospital in southern Taiwan were recruited into this study. Their attitudes toward homosexual people as recorded on the Attitudes Toward Homosexuality Questionnaire, intention to provide care to homosexual individuals, and related factors were examined. The results revealed that psychiatric nurses who had a bachelor's or master's degree, higher level of knowledge about homosexuality, and friends or relatives with a homosexual orientation had a more positive attitude toward homosexuality. These psychiatric nurses, with more positive attitudes, and who worked in the medical center or regional teaching hospitals had a higher intention to care for homosexual people. The factors related to attitudes toward homosexuality and intention to care for homosexual people identified in this study should be taken into consideration when intervening in psychiatric nurses' attitudes toward homosexuality and intention to care for homosexual people.

Factors associated with student nurses' intent to provide physical and psychosocial care to persons with acquired immunodeficiency syndrome.

This project examined the influence of selected factors on student nurses' intent to provide physical and psychosocial care to persons hospitalized with acquired immunodeficiency syndrome (AIDS). Respondents were 125 undergraduate upper division nursing majors attending a state-supported university. Questionnaires were distributed to student mailboxes and were returned anonymously through the United States Postal Service. All factors were correlated with intent to provide physical care and with intent to provide psychosocial care using Pearson product-moment correlation coefficients. For both intention scales, attitude toward a person with AIDS acquired through homosexual activity and attitude toward a person with AIDS acquired through sharing needles were positively related to intent to provide care. Homophobia, fear of AIDS, and perceived susceptibility toward acquiring human immunodeficiency virus from providing care were inversely related. These findings are useful for designing programs that promote the delivery of compassionate nursing care to persons with AIDS.

Maternal judgments of intentionality in young children with autism: the effects of diagnostic information and stereotyped behavior.

This study examined the relation among maternal judgment of intentionality and variables relevant to families of children with autism. Thirty-six mothers of children with autism rated segments of home videotape of behavior from very young children later diagnosed with autism. Mothers were randomly assigned to either a diagnostic or a no diagnostic information group. No significant difference was found on overall ratings of intentionality. Maternal stress was not correlated with overall ratings of intentionality for either group. Mothers in the diagnostic information group rated stereotyped behavior as less intentional. Post hoc analyses showed no differences on maternal ratings of intentionality when the child was in a social setting or interacting with an object, but there were significant differences between ratings when the child was alone. The results are discussed in relation to early development and identification issues in autism.

Impact of health beliefs, quality of life, and the physician-patient relationship on the treatment intentions of inflammatory bowel disease patients.

The research tested a model of treatment decision making in chronic illness that includes health beliefs, quality of life, and relationship with the physician (shared or not). Inflammatory bowel disease patients (N = 218) reported on their physician-patient relationship, general and disease-specific quality of life, and intentions to take a drug, for which perceived benefits and costs were manipulated. For more symptomatic patients, both costs and benefits predicted intentions; however, for less symptomatic patients, costs played a more important role. Physician recommendation predicted intention primarily among those who shared a decision-making relationship with their physician. Overall, the model accounted for 57.8% of the variance in medication-taking intention. Findings suggest that an integrative consideration of relationship factors, health beliefs, and health status may help explain treatment intentions among the chronically ill.

Turnover intentions and voluntary turnover: the moderating roles of self-monitoring, locus of control, proactive personality, and risk aversion.

This article explores moderators of the relationship between turnover intentions and turnover behavior to better explain why some employees translate intentions into behavior and other employees do not. Individual differences in self-monitoring, locus of control, proactive personality, and risk aversion were examined. Results indicate that self-monitoring and risk aversion moderate the intentions-turnover link. Specifically, the relationship between turnover intentions and turnover is stronger for low self-monitors and those lower in risk aversion. Locus of control moderated the relationship in 1 of 2 samples such that the relationship was stronger for those with an internal locus of control. Proactive personality, however, did not directly moderate the relationship between intentions and turnover behaviors.

Intentions to work during terminal illness: an exploratory study of antecedent conditions.

Facing a terminal illness is an unimaginably difficult experience, yet many individuals intend to work despite their prognosis. However, research has not systematically examined the potential antecedents underlying such intentions. Using behavioral intention theory as an underlying framework, this study hypothesized that reasons for working (intrinsic and extrinsic), the will to live, disability severity, accessibility of travel, and age would predict intentions to work during terminal illness. A representative sample of medically diagnosed amyotrophic lateral sclerosis (a.k.a. Lou Gehrig's disease) patients with a mean life expectancy of approximately 3 years participated (mean age=57.8 years). Controlling for length of diagnosis, employment status, and demographic variables, results indicated that intrinsic reasons were particularly strong predictors of intentions, followed by age, disability severity, and accessibility of travel. Exploratory findings also indicated that behavioral intentions were positively related to future employment status, consistent with past theory. ((c) 2005 APA, all rights reserved).

Evidence that implementation intentions promote transitions between the stages of change.

A dietary change intervention based on Gollwitzer's (1993) concept of implementation intentions was used to see whether transitions between transtheoretical model stages could be induced in a field experiment. Participants (N=554) were randomized to receive either questionnaire-only or questionnaire-plus-implementation intention. Results showed that, controlling for variables from the theory of planned behavior, implementation intentions helped a significantly greater number of people to progress through the stages of change than did receiving the questionnaire alone. However, the implementation intention intervention did not prevent regression from the stages of change. The discussion focuses on the importance of targeting implementation intention interventions and on the future use of health professional-led analyses of critical situations and precise identification of appropriate responses to prevent regression.

Understanding action control: predicting physical activity intention-behavior profiles across 6 months in a Canadian sample.

Intention is theorized as the proximal determinant of behavior in some theories of motivation, but the need to understand predictors of action control (i.e., translating an intention into behavior) is warranted to tailor physical activity intervention efforts. The purpose of this study was to examine constructs of the transtheoretical model of behavior change (TTM) as predictors of physical activity intention-behavior profiles across 6 months in a large Canadian sample (N = 1,192). Results showed that 5 of the 8 possible intention-behavior profiles had a substantial number of participants: nonintenders, unsuccessful adopters, successful adopters, unsuccessful maintainers, and successful maintainers. Constructs of the TTM distinguished (p < .01) intention-behavior profiles. Self-efficacy and the behavioral processes of change were particularly good predictors of action control (p < .01), but disaggregated beliefs and processes identified specific intervention targets for successful physical activity adoption and maintenance. The results validate that both action planning and action control are important when understanding physical activity behavior.

Personality predictors of the development of elementary school children's intentions to drink alcohol: the mediating effects of attitudes and subjective norms.

The authors tested a mediation model in which childhood hostility and sociability were expected to influence the development of intentions to use alcohol in the future through the mediating mechanisms of developing attitudes and norms. Children in 1st through 5th grades (N=1,049) from a western Oregon community participated in a longitudinal study involving 4 annual assessments. Hostility and sociability were assessed by teachers' ratings at the 1st assessment, and attitudes, subjective norms, and intentions were assessed by self-report at all 4 assessments. For both genders, latent growth modeling demonstrated that sociability predicted an increase in intentions to use alcohol over time, whereas hostility predicted initial levels of these intentions. These personality effects were mediated by the development of attitudes and subjective norms, supporting a model wherein childhood personality traits exert their influence on the development of intentions to use alcohol through the development of these more proximal cognitions.

Youth exercise intention and past exercise behavior: examining the moderating influences of sex and meeting exercise recommendations.

The study purposes were to examine: (a) the determinants of exercise intention and past exercise behavior (PEB) using the theories of reasoned action and planned behavior, and (b) the moderating influences of sex and exercise group (meeting or not meeting exercise guidelines). Participants (n = 676 adolescents) completed self-reported measures of their exercise attitude, subjective norm, perceived behavioral control (PBC), intention, and PEB. We found that attitude, subjective norm, and PBC explained 55% of the variance in intention, and intention and PBC explained 51% of the variance in PEB. While we found sex and exercise group differences across the study measures, we did not find evidence of significant moderation. Thus, the theory constructs predicted intention and PEB similarly across sex and exercise groups.

Using a web-based survey to assess correlates of intention towards HIV testing among never-been-tested but sexually experienced college students.

The purpose of this study is to identify influential psychosocial factors predicting testing intention among college students who have never been tested but are sexually experienced. A web-based survey was conducted during the spring semester in 2003 in a major Southeastern university (N = 440). Results showed only 7.7% of the students expressed intention despite having been sexually experienced. Multiple logistic regression models showed that the combined five psychosocial factors examined (perceived pros, cons, risk, self-efficacy and availability/accessibility related to testing) significantly predicted testing intention (p < 0.001). Two factors, perceived pros (OR = 1.641) and perceived risk (OR = 1.357), showed significant coefficients. The reduced model with only these two predictors showed increased correct classification of students in terms of their testing intention (from 91.8 to 93.4%). Results suggested that educational and prevention programmes aimed at encouraging testing should address these important testing-related psychosocial constructs to maximize programme impacts. Future studies need to further investigate the role of other factors in affecting testing intention or related behaviours among other sub-groups of students.

Free recall of everyday retrospective and prospective memories: the intention-superiority effect is moderated by action versus state orientation and by gender.

Individual differences in the relative accessibility of everyday memories were investigated. Based on the theory of action control described by Kuhl and colleagues (Kuhl and Beckmann, 1994b), an intention-superiority effect (heightened activation and accessibility of intentions--i.e., prospective memories--compared to retrospective memories) was predicted for state-oriented individuals, but not action-oriented individuals. As predicted, only state-oriented individuals showed an intention-superiority effect, recalling more prospective than retrospective real-life memories. In addition, females, but not males, showed an intention-superiority effect in retrieval of the most accessible memories, memories recalled in the first minute. These results show important moderator variables for the intention-superiority effect and extend previous research to real-life, everyday memories.

Preconceptional cystic fibrosis carrier screening: attitudes and intentions of the target population.

The aim of this study was to assess the attitudes and intentions of individuals planning a pregnancy with regard to preconceptional cystic fibrosis (CF) carrier screening and to determine factors associated with a positive and negative/neutral intention to have the test. A survey, based on a questionnaire, was conducted among a stratified random sample of 303 recently married couples (606 individuals). Of the eligible individuals, 70% (n = 380) participated. Of the respondents, 73% had a positive attitude toward a routine offer of preconceptional CF carrier screening, and 56% had the intention to participate in a screening program. A positive intention to have the test was associated with high perceived anticipation of regret, intended preconceptional behavior, high perceived pressure from experts, high perceived consequences of the test results, low perceived barriers, and low perceived negative consequences for family members. These results suggest that the offer of routine preconceptional CF carrier screening would lead to substantial acceptance among couples planning a pregnancy. Several variables related with intention were identified.

Understanding successful behaviour change: the role of intentions, attitudes to the target and motivations and the example of diet.

Although many attempts to change health behaviour fail, some individuals do show successful behaviour change. This study assessed the role of behavioural intentions, motivations and attitudes to the target in explaining successful changes in diet with a particular focus on positive and negative intentions and positive and negative attitudes. Participants (n=282) completed a questionnaire describing a recent change in eating behaviour (becoming a vegetarian, cutting out a food group, eating fewer calories), their intentions, their attitudes to the food being avoided, a range of motivations and their degree of success. The results showed that the three behaviour change groups differed in terms of their cognitions with those trying to eat fewer calories reporting less success in changing their behaviour. Successful vegetarianism was associated with a lower positive attitude; successfully cutting out a food group was related to ethical motivations, a lower positive attitude and greater positive and negative intentions, and reducing calorie intake was associated with greater positive intentions and a lower positive attitude. Therefore, success was associated with different cognitions depending upon the type of change being made, although cognitions such as 'I will eat more vegetables' and 'I no longer find high fat foods palatable' were consistently most predictive of success. Suggestions for the development of more effective interventions to change health behaviours are made.

Parental pregnancy intention and early childhood stunting: findings from Bolivia.

BACKGROUND: This study examined the impact of maternally reported pregnancy intention, differentiating unwanted and mistimed pregnancies, on the prevalence of early childhood stunting. Additionally, it examined the influence of paternal pregnancy intention status. METHODS: Data were collected from a nationally representative sample of women and men interviewed in the 1998 Bolivia Demographic and Health Survey. The sample was restricted to lastborn, singleton children younger than 36 months who had complete anthropometric information. Multivariable logistic regression examined the association between pregnancy intention and stunting. RESULTS: Children from unwanted and mistimed pregnancies comprised 33% and 21% of the sample, respectively. Approximately 29% of the maternally unwanted children were stunted as compared to 19% among intended and 19% among mistimed children. Children 12-35 months (toddlers) from mistimed pregnancies (adjusted prevalence risk ratio [PR(adj)] 1.33, 95% confidence interval [CI]: 1.03-1.72) and unwanted pregnancies (PR(adj) 1.28, 95% CI: 1.04-1.56) were at about a 30% greater risk for stunting than children from intended pregnancies. Infants and toddlers with both parents reporting them as unwanted had an increased risk of being stunted as compared with children both of whose parents intended the pregnancy. No association was found for infants less than 12 months. CONCLUSIONS: Reducing unintended pregnancies in Bolivia may decrease the prevalence of childhood growth stunting. Children born to parents reporting mistimed or unwanted pregnancies should be monitored for growth stunting, and appropriate interventions should be developed. Measurement of paternal pregnancy intention status is valuable in pregnancy intention studies.
