    Input: AIM this paper reports the results of a nursing-administered theory-based intervention , the " Moving Heart Program " , based on the implementation intention theory and pointed at improving physical activity adherence among coronary heart disease out patients in Brazil . METHODS this experimental study applied assessment s at baseline , 1 and 2 months after baseline . The Consoli date d St and ards of Reporting Trials statement was followed . Participants were r and omly assigned to intervention , comprising action and coping plans on how to deal with anticipated barriers  ( n=69 ) , or a st and ard-care control group ( n=67 ) . RESULTS participants su bmi tted to the intervention showed significant higher levels of physical activity 2 months after baseline and were significantly more active than the control group . CONCLUSIONS the results indicate that the intervention is feasible for patients with coronary heart disease and can be a useful tool to facilitate intended lifestyle changes . This study brings relevant contributions to the Nursing field and other health-related areas , once the intervention presents low cost to health services and can be applied in cardiac rehabilitation programs , showing significant benefits to participants OBJECTIVE This study compared a motivational intervention based on protection motivation theory ( PMT , Rogers , 1975 , 1983 ) with the same motivational intervention augmented by a volitional intervention based on implementation intentions ( Gollwitzer , 1993 ) . DESIGN The study had a longitudinal design , involving three waves of data collection over a 2-week period , incorporating an experimental manipulation of PMT variables at Time 1 and a volitional , implementation intention intervention at Time 2 . METHOD Participants ( N=248 ) were r and omly allocated to a control group or one of two intervention groups .  Cognitions and exercise behaviour were measured at three time-points over a 2-week period . RESULTS The motivational intervention significantly increased threat and coping appraisal and intentions to engage in exercise but did not bring about a significant increase in subsequent exercise behaviour . In contrast , the combined protection motivation theory/implementation intention intervention had a dramatic effect on subsequent exercise behaviour . This volitional intervention did not influence behavioural intention or any other motivational variables . CONCLUSIONS It is concluded that supplementing PMT with implementation intentions strengthens the ability of the model to explain behaviour . This has implication s for health education programmes , which should aim to increase both participants ' motivation and their volition Background Forming implementation intentions ( specifying when , where and how to act ) has been proposed as a potentially effective and inexpensive intervention , but has mainly been studied in controlled setting s for straightforward behaviors . Purpose To examine if forming implementation intentions ( II ) could be used in large-scale , population -based interventions that aim to promote more complex and clinical ly relevant behavior change , we tested the impact of different II on increasing daily physical activity ( PA ) aim ed at weight maintenance among 709 Dutch adults . Methods At T0 , participants were r and omly allocated to a control group or to form II for 1 ) a prescribed action ( walking ) , 2 ) self-selected activities , 3 ) self-selected activities and repeat making these II two times . All participants were asked to increase PA  by at least two hours a week ( 15–20 minutes per day ) . Post-tests took place two weeks ( response 85 % ) , three months ( response 78 % ) and six months ( response 79 % ) post-intervention . Results No main effects of II formation on BMI or physical activity were found . Intention to increase physical activity moderated the effects of repeated II , but not of the other II conditions . Forming repeated II had a positive effect on total PA and number of active days for respondents with strong intentions . Conclusion Implementation intention interventions may not yet be ready for implementation on its own for large-scale obesity prevention in the general public . Future research should test strategies for optimal II formation in both initiating and maintaining behavioral change . Trial registration IS RCT OBJECTIVE To test the efficacy in promoting brisk walking of two theory-based interventions that incorporate implementation intentions and text message ( Short Message Service ; SMS ) reminders directed at one 's walking-related plans or goals . DESIGN Participants ( N = 149 ) were r and omized to one of three conditions ( implementation intention + SMS plan reminder , implementation intention + SMS goal reminder , control ) before completing measures at baseline and follow-up 4 weeks later . At follow-up , the experimental groups were given a surprise recall task concerning their plans . All participants completed an equivalent goal recall task . MAIN OUTCOME MEASURES Vali date d self-report measures of physical activity and measures of implementation intention and goal recall , weight , and waist-to-hip ratio . RESULTS Both intervention groups increased their brisk walking relative to the control group , without reducing other physical activity . The goal reminder group lost the most weight . The SMS plan reminder group recalled more of their plans than the SMS goal reminder group , but the latter were more successful in goal recall . CONCLUSION Both interventions can promote brisk walking in sedentary population s. Text messages aid the recall of , and could enhance interventions that target , implementation intentions and goals The paper investigates the relations between involvement in an implementation intention intervention programme , frequency of the use of a self-regulatory physical activity planning strategy , and moderate physical activity among patients who had suffered myocardial infa rct ion ( MI ) . It examines whether effects of the implementation intention intervention on behavior change was mediated by change in the use of a planning strategy . A total of 114 patients from central and northern Pol and took part in the study after their first uncomplicated MI . Data were collected individually at approximately 1 week after MI ( Time 1 ) , 2 weeks after short-term rehabilitation ( about 8 weeks after MI : Time 2 ) , and 8 months after MI ( Time 3 ) . After data collection at Time 2 , patients were r and omly assigned to the control group or the intervention group . Patients who participated in the implementation intention intervention maintained the same number of sessions of moderate physical activity at 8 months after MI ( Time 3 ) as at 2 weeks after rehabilitation ( Time 2 ) . By contrast , patients from the control group performed significantly fewer sessions of moderate physical activity at Time 3 , compared to Time 2 . The intervention result ed in the more frequent use of a planning strategy  at 8 months after MI . Change in the frequency of the use of a planning strategy completely mediated effects of the intervention on change in physical activity . Only patients who participated in the implementation intention intervention and increased their use of a planning strategy  adhered to the recommended three or more sessions of moderate physical activity per week The aim of this study was to assess the effects of implementation intentions on leisure-time physical activity , taking into account the stability of intention . At baseline ( T0 ) , 349 participants completed a psychosocial question naire and were r and omly assigned to implementation intention or control condition . Three months after baseline assessment ( T1 ) , participants in the experimental group were asked to plan where , when , and how they would exercise . Leisure-time physical activity was assessed 3 mo . later ( i.e. , at 6-mo . follow-up ; T2 ) . The intervention had no significant effect on physical activity at 6-mo . follow-up . However , a significant interaction of group and intention stability was observed , with the effect of the intervention on behaviour statistically significant only among those with unstable intention . Intention stability thus moderated the effect of the intervention , i.e. , the intervention was more successful among individuals who needed support to change ( unstable intenders ) Implementation intentions planning in advance the situation in which one will act , have been proposed to be an effective self-regulatory technique for changing health behaviour . Encouraging people to receive text message reminders of their implementation intentions should enhance their strength and , thus , it was predicted that this combined approach would be particularly effective in increasing exercise .  Participants ( N = 155 ) were r and omly allocated to one of five conditions ( implementation intentions and SMS , implementation intention , SMS or one of two control groups ) then completed self-report measures of exercise behaviour and motivation . Four weeks later , they responded to similar items . Results suggested that the combined intervention increased exercise frequency significantly more than the other strategies including the implementation intention group . It is proposed , therefore , that implementation intention effects can be enhanced via plan reminders OBJECTIVE The trial investigates the effects of augmenting an established weight-reduction intervention with implementation intention prompts . DESIGN Fifty-five overweight or obese women ( ages 18 to 76 years ; body mass index from 25.28 to 48.33 ) enrolled in a commercial weight reduction program were r and omly assigned to either an implementation intention prompt or a control condition . Data were collected twice , with a time gap of 2 months . MAIN OUTCOME MEASURES The primary outcome was participants ' change in weight and body mass index from preintervention to follow-up . RESULTS Repeated measures analysis of variance revealed a significant Time = Condition interaction : On average , implementation intention prompt participants lost 4.2 kg ( 95 % confidence interval = 3.19 , 5.07 ) , whereas control participants lost 2.1 kg ( 95 % confidence interval = 1.11 , 3.09 ) . The change in frequency of planning mediated the effects of the intervention on weight and body mass index change . CONCLUSION Among obese or overweight women participating in a commercial weight loss program , those who learn to form implementation intentions can achieve greater weight reduction . Planning facilitation is a key mechanism explaining enhanced weight loss generated by implementation intention formation Type II diabetes mellitus is a highly prevalent disease among the adult Brazilian population , and one that can be controlled by interventions such as physical activity , among others . The aim of this r and omized controlled study was to evaluate the impact of a traditional motivational strategy , associated with the activation of intention theory , on adherence to physical activity in patients with type II , diabetes mellitus who are part of the Unified Health System ( SUS ) . Participants were divided into a control group ( CG ) and an intervention group ( IG ) . In both groups , the traditional motivational strategy was applied , but the activation of intention strategy was only applied to the IG Group . After a two-month follow-up , statistically significant differences were verified between the groups , related to the practice of walking ( p = 0.0050 ) , number of days per week ( p = 0.0076 ) , minutes per day ( p = 0.0050 ) and minutes walking per week ( p = 0.0015 ) . At the end of the intervention , statistically significant differences in abdominal circumference ( p = 0.0048 ) between the groups were observed . The conclusion drawn is that the activation of intention strategy had greater impact on adherence to physical activity and reduction in abdominal circumference in type II diabetics , than traditional motivational strategy
