Do implementation intentions help to turn good intentions into higher fruit intakes?

OBJECTIVE: The present study examined (1) whether respondents who were encouraged to make implementation intentions to eat more fruit increased their fruit intakes, as measured by three measures of fruit intake; (2) whether the effects of implementation intentions on fruit intake were dependent on positive goal intentions at baseline; and (3) the respondents' commitment to perform their implementation intentions. DESIGN: Dutch adults (n = 535) were randomly assigned to either receive implementation intention instructions or not. Two questionnaires were completed with a 1.5-week time interval. Respondents in the implementation intention condition were asked to form implementation intentions to eat an extra serving of fruit per day during one week. RESULTS: Respondents in the implementation intention group reported a high frequency of eating an extra serving of fruit per day. The implementation intention effect on frequency of extra fruit did not depend on goal intention at baseline. The more committed respondents were to carrying out their implementation intention, the more likely they were to increase their fruit intake. CONCLUSION: These results provide some indications that implementation intentions could be a useful strategy to induce a short-term increase in fruit intake.

The interplay between goal intentions and implementation intentions.

Two studies tested whether action control by implementation intentions is sensitive to the activation and strength of participants' underlying goal intentions. In Study 1, participants formed implementation intentions (or did not) and their goal intentions were measured. Findings revealed a significant interaction between implementation intentions and the strength of respective goal intentions. Implementation intentions benefited the rate of goal attainment when participants had strong goal intentions but not when goal intentions were weak. Study 2 activated either a task-relevant or a neutral goal outside of participants' conscious awareness and found that implementation intentions affected performance only when the relevant goal had been activated. These findings indicate that the rate of goal attainment engendered by implementation intentions takes account of the state (strength, activation) of people's superordinate goal intentions.

Prediction of "intent", "discrepancy with intent", and "discrepancy with nonintent" for the patient with chronic pain to return to work after treatment at a pain facility.

OBJECTIVE: We previously determined that "intent" to return to work post pain facility treatment is the strongest predictor for actual return to work. The purposes of the present study were the following: to identify variables predicting "intent"; to predict membership in the "discrepant with intent" group [those chronic pain patients (CPPs) who do intend to return to work but do not]; and to predict membership in the "discrepant with nonintent" group (those CPPs who do not intend to return to work but do). DESIGN: A total of 128 CPPs completed a series of rating scales and yes/no questions relating to their preinjury job perceptions and a question relating to "intent" to return to the same type of preinjury job post-pain facility treatment. These CPPs were part of a grant study for prediction of return to work, and therefore their work status was determined at 1, 3, 6, 12, 18, 24, and 30 months posttreatment. Preinjury job perceptions and other demographic variables were utilized using stepwise discriminant analysis to identify variables predicting "intent" and predicting membership in the "discrepant with intent" and "discrepant with nonintent" groups. SETTING: Pain facility (multidisciplinary pain center). PATIENTS: Consecutive low back pain CPPs, mean age 41.66+/-9.54 years, with the most frequent highest educational status being high school completion (54.7%) and 60.2% being worker compensation CPPs. RESULTS: "Intent" was predicted by (in decreasing order of probability) postinjury job availability variables, job characteristic variables, and a litigation variable. "Discrepant with intent" was predicted by (in decreasing order of probability) for the 1-month follow-up time point, postinjury job availability variables, pain variables, a litigation variable, and a function perception variable, and for the final follow-up time point, pain variables only. "Discrepant with nonintent" was predicted by (in order of decreasing probability) for the 1-month follow-up time point, a job availability variable, a demographic variable, and a functional perception variable, and for the final follow-up time point a pain variable and a job availability variable. The percentage of CPPs correctly classified by each of these analyses was as follows: "intent" 81.25%, "discrepant with intent" 87.01% (at 1-month follow-up) and 74.03% (final follow-up), "discrepant with nonintent" 92.16% (at 1-month follow-up) and 75.00% (final follow-up). CONCLUSIONS: CPPs intentions of returning to their preinjury jobs are mainly determined by job availability and job characteristic variables but surprisingly not by pain variables. However, the results with "discrepant with intent" and "discrepant with nonintent" groups indicate that actual return to work is determined by an interaction between job availability variables and pain variables with pain variables predominating for long-term outcome.

Role of anticipated regret, intentions and intention stability in adolescent smoking initiation.

OBJECTIVES: To examine the impact of anticipated regret within the theory of planned behaviour (TPB) on intentions of adolescents to initiate smoking. To examine the moderating role of anticipated regret and intention stability on the relationship between intentions and smoking initiation in adolescents. METHODS: We conducted two studies measuring anticipated regret within the TPB applied to adolescent smoking initiation. In the first study, 347 non-smoking adolescents (between 11 and 12 years of age) completed the TPB and anticipated regret measures about smoking initiation. In the second study, 675 non-smoking adolescents (between 11 and 12 years of age) completed the TPB, anticipated regret, and intention stability measures in relation to smoking initiation. Smoking was assessed objectively by carbon monoxide breath monitor 9 months later. RESULTS: In Studies 1 and 2, regret significantly added to predictions of intentions over and above components of the TPB (p < .001). In Study 2, smoking behaviour was predicted by intentions and the relationship of intentions to behaviour was moderated by regret and intention stability. CONCLUSIONS: Regret and intention stability were shown to be important variables within the TPB in understanding intentions and behaviour of smoking initiation in adolescents.

How the brain understands intention: different neural circuits identify the componential features of motor and prior intentions.

In this paper we present theoretical and experimental evidence for a set of mechanisms by which intention is understood. We propose that three basic aspects are involved in the understanding of intention. The first aspect to consider is intention recognition, i.e., the process by which we recognize other people's intentions, distinguishing among different types. The second aspect concerns the attribution of intention to its author: the existence of shared neural representations provides a parsimonious explanation of how we recognize other people's intentions (what they are doing), but in and of itself, is not sufficient to determine who the agent is. Once the intention has been recognized and attributed to an agent, the reasons for, and the aim of, the intention are to be considered. Hence, the third aspect concerns the aim-intention motivating the execution of a certain action. We discuss the neural basis of these three theoretical aspects suggesting a conceptual synthesis.

Mediator of moderators: temporal stability of intention and the intention-behavior relation.

Intention certainty, past behavior, self-schema, anticipated regret, and attitudinal versus normative control all have been found to moderate intention-behavior relations. It is argued that moderation occurs because these variables produce "strong" intentions. Stability of intention over time is a key index of intention strength. Consequently, it was hypothesized that temporal stability of intention would mediate moderation by these other moderators. Participants (N = 185) completed questionnaire measures of theory of planned behavior constructs and moderator variables at two time points and subsequently reported their exercise behavior. Findings showed that all of the moderators, including temporal stability, were associated with significant improvements in consistency between intention and behavior. Temporal stability also mediated the effects of the other moderators, supporting the study hypothesis.

Verbally expressed intentions of parasuicide: I. characteristics of patients with various intentions.

Comparisons of 584 parasuicides with a verbalized intention to die and 341 parasuicides with other intentions were made on a number of sociodemographic and clinical/psychological variables. The results revealed that patients with a verbalized intention to die had different life-problems than those with other intentions. More specifically, after sex and age had been controlled for, patients with an intention to die were more often economically inactive and were more likely to report psychiatric problems as their main concern, while those with other intentions more often abused alcohol and were more likely to report family or economical problems. The identification of discriminating risk factors is important in light of the fact that those with an intention to die made more life-threatening attempts, as reflected by the choice of method and the medical judgment of the attempt's seriousness.

Suicidal intent in deliberate self-harm and the risk of suicide: the predictive power of the Suicide Intent Scale.

BACKGROUND: Suicidal intent at the time of deliberate self-harm (DSH) is known to be associated with risk of future suicide in DSH patients. The predictive power of suicidal intent to identify particular individuals who are at high risk of suicide is unclear. METHOD: Clinical and demographic data on 4156 DSH patients presenting to hospital 1993 and 1997 were analysed. Follow-up information on eventual suicide was available for 2489 patients (mean follow-up 5.2 years). The predictive value of the Beck Suicidal Intent Scale (SIS) was examined using Receiver Operating Characteristic (ROC) plots. RESULTS: Thirty males (2.9%) and 24 females (1.7%) died by suicide. Despite a robust association between suicidal intent and eventual suicide, the positive predictive value (PPV) of the SIS was low (4%). Predicted probabilities of suicide assigned to individual patients were also low, even for those who eventually died by suicide. LIMITATIONS: Assessment and follow-up information was not available for all patients. CONCLUSIONS: The SIS cannot predict which individual patients will ultimately die by suicide. Nonetheless, information regarding suicidal intent is valuable in the clinical risk assessment and management of DSH patients.

Actions, intentions, and self-assessment: the road to self-enhancement is paved with good intentions.

Actions and intentions do not always align. Individuals often have good intentions that they fail to fulfill. The studies presented here suggest that actors and observers differ in the weight they assign to intentions when deciding whether an individual possesses a desirable trait. Participants were more likely to give themselves credit for their intentions than they were to give others credit for theirs (Studies 1 and 2). This caused individuals to evaluate themselves more favorably than they evaluated others (Studies 3-5). Discussion focuses on the motivational and information-processing roots of this actor-observer difference in the weight assigned to intentions as well as the implications of this tendency for everyday judgment and decision making.

Implementation intentions, perfectionism, and goal progress: perhaps the road to hell is paved with good intentions.

Two studies explored whether perfectionism moderates the impact of implementation intentions on goal progress. Study 1 used an implementation intention manipulation to examine the effects of these plans in interaction with perfectionism on the progress of New Year's resolutions. Study 2 added a repeated implementation intention condition and monitored affect and monthly goal progress. The results of both studies revealed a significant backfire effect of the implementation intentions on goal progress for participants high on a particular dimension of perfectionism (socially prescribed perfectionism). These perfectionists reported doing significantly worse at reaching their personal goals when they were asked to formulate implementation intentions than when they completed a control exercise. There also was evidence that implementation planning aroused negative affect for socially prescribed perfectionists. These results are the first to suggest that implementation planning may be contra-indicated for individuals with self-critical tendencies.

Fertility intentions and subsequent fertility behaviour in Matlab: do fertility intentions matter?

This study examines the extent of the interrelationship between future fertility intention and subsequent fertility behaviour in rural Bangladesh using longitudinal data. It confirms that fertility intention is an important predictor of subsequent fertility behaviour for rural Bangladeshi women. Women wanting no more children are over three times less likely to have a child during a 5-year follow-up than those wanting more children. A multivariate model using logistic regression shows that fertility intention is a useful indicator for fertility behaviour, when background and life-cycle variables are controlled. The different patterns of fertility intentions by socioeconomic and demographic subgroups suggest that different programme strategies should be designed for specific target groups.

Relationships among patient satisfaction, intent to return, and intent to recommend services provided by an academic nursing center.

Patient satisfaction is an indicator and component of high quality care and service and the viability of academic nursing centers is dependent on patients' return visits and new patients' visits. The major purpose of this study was to determine patients' satisfaction with the quality of health care services provided by an academic nursing center. A secondary purpose was to determine the relationships among patient satisfaction, intent to return, and intent to recommend services. The study consisted of a convenience sample of 107 adult patients who responded to an investigator generated patient satisfaction survey. Findings indicated that 94 (87.8%) of the patients were satisfied. Stepwise regression analysis identified treatment with respect, the rating of care received, and the helpfulness of the person at the front desk as the strongest predictors of patient satisfaction. Correlation analysis revealed that patient satisfaction is highly correlated with intent to return and intent to recommend services (p < .01).

[Nurse turnover: A differential analysis of the predictors for intent to change the job and intent to leave the profession].

In a cross-sectional questionnaire study predictors for the intent to leave the nursing profession on the one hand and predictors for the intent to change the job within the nursing profession on the other hand are examined. Data were collected by a national survey of nursing personnel in Germany. The sample of the study consists of 454 nurses working in acute care hospitals. As possible predictors work-related psychological stress, the strain due to illness and behaviour of the patients, psychosomatic pains, organisational, structural as well as sociodemographic variables are taken into account. The relevant predictors are identified by two multiple, linear regression analyses. Psychosomatic pains, low decision latitude, high psychological job demands, short job tenure, the strain due to aggressive and nagging patients, bad cooperation between doctors and nurses, low support by the supervisor and professional status (supervising position) turn out to be predictive for the intent to leave the nursing profession (R2 = 30%). For the intent to change the job within the profession significant predictors are low social support by colleagues, low support by the supervisor, psychosomatic pains, age, short job tenure, and the number of beds in the unit (R2 = 44%). The results indicate, that for the prevention of professional exit early individual measures should be taken where-as the improvement of communication and cooperation among colleagues could keep nurses from job rotation within the profession.

Factors affecting the intention-physical activity relationship: intention versus expectation and scale correspondence.

The present study examined two issues believed to be relevant for the application of the theory of planned behavior to the physical activity domain: (a) the conceptual distinction between intention and expectation and (b) the effect of failing to obtain scale correspondence (Courneya & McAuley, 1993). Subjects for the study were 170 undergraduate students who completed an initial questionnaire assessing the constructs of interest and follow-up self-reports of physical activity at 2 and 4 weeks. Results indicated that: (a) expectation shared 9% more variance with frequency of physical activity than did intention, and (b) scale correspondence significantly improved the correlation between intention and physical activity. Discussion focused on conceptual and methodological issues concerning the theory of planned behavior as applied to physical activity.

Application of an objective method of assessing intention tremor - a further study on the use of weights to reduce intention tremor.

Thirty-one patients with intention tremor due to a variety of causes were subjected to measurements of their intention tremor. The effect of varying amounts of lead weights on the amount of limb tremor recorded was noted. It is concluded that simple methods of treatment may be of benefit, and that an objective method of measuring intention tremor overcomes many of the difficulties of a clinical trial of this type. The method described yields quantifiable data which can be subjected to statistical analysis to help overcome the problem of variability. Bias in the results due to practice or fatigue effects has proved negligible. An optimum amount of lead, which was usually between 600 and 840 g, has been noted.

The intentional spring: a strategy for modeling systems that learn to perform intentional acts.

In motor task learning by instruction, the instructor's skill and intention, which, initially, are extrinsic constraints on the learner's perceiving and acting, eventually become internalized as intrinsic constraints by the learner. How is this process to be described formally? This process takes place via a forcing function that acts both as an anticipatory (informing) influence and a hereditary (controlling) influence. A mathematical strategy is suggested by which such intentions and skills might be dynamically learned. A hypothetical task is discussed in which a blindfolded learner is motorically instructed to pull a spring to a specific target in a specific manner. The modeling strategy involves generalizing Hooke's law to the coupled instructor-spring-Learner system. Specifically, dual Volterra functions express the anticipatory and hereditary influences passed via an instructor-controlled forcing function on the shared spring. Boundary conditions (task goals) on the instructor-spring system, construed as a mathematical (self-adjoint) operator, are passed to the learner-spring system. Psychological interpretation is given to the involved mathematical operations that are passed, and mathematical (Hilbert-Schmidt's and Green's function) techniques are used to account for the release of the boundary conditions by the instructor and their absorption by the learner, and an appropriate change of their power spectra.

A United Methodist approach to end-of-life decisions: intentional ambiguity or ambiguous intentions.

The position of the United Methodist Church on end-of-life decisions is best described as intentional ambiguity or ambiguous intentions or both. The paper analyzes the official position of the denomination and then considers the actions of a U.M.C. bishop who served as a foreman for a trial of Dr. Jack Kevorkian. In an effort to find some common ground within an increasingly divided denomination, the work concludes with a consideration of the work of John Wesley and his approach to human death.
