Evaluating the utility of temporal self-regulation theory for understanding physical activity outcomes in a behavioral weight loss maintenance program

Objective Physical activity (PA) is critical for weight loss maintenance (WLM) success. Clarifying mechanisms behind PA engagement may suggest new WLM intervention targets. This study examined an application of temporal self-regulation theory (TST) to enhance our understanding of PA during WLM. Methods and measures Participants (n = 214) who achieved a ≥ 5% weight loss during a 4-month weight loss intervention were recruited into an 18-month WLM trial. TST constructs (i.e. PA beliefs, intention, behavioral prepotency, self-regulatory capacity) were measured via self-report measures. PA was subsequently assessed over a 7-day period with waist-worn Actigraph GT9X. Robust linear regression models and generalized linear mixed models tested the association between PA beliefs and intention, and the associations between intention, behavioral prepotency, self-regulatory capacity and device-measured PA at baseline and 18-months. Results Short-term positive beliefs were associated with intention at baseline and 18-months, whereas short-term negative beliefs were associated with intention at 18-months only. Intention was associated with moderate/vigorous PA (MVPA) minutes and bouted MVPA at baseline and 18-months. The intention by self-regulatory capacity interaction was significant at baseline. Conclusion Findings lend some support for the use of TST for understanding PA and suggest that short-term beliefs about PA may represent a meaningful target for intervention.

Why we don't eat as intended: Moderators of the short-term intention-behaviour relation in food intake.

A healthy diet is essential for preventing chronic disease and promoting overall health. Translating one's intention to eat healthy into actual behaviour has, however, proven difficult with a range of internal and contextual factors identified as driving eating behaviour. We leverage Temporal Self-Regulation Theory to examine these momentary determinants' direct and moderating effects on the intention-behaviour relation with Ecological Momentary Assessment (EMA). Eighty-seven healthy participants (mage = 24.1 years; 59 women, 28 men) reported, 5 times daily for 10 weekdays, their intentions to stick to a self-set dietary restriction goal for the next 3 hr, the goal congruency of their eating behaviour in the past 3 hr, and a range of factors potentially influencing food intake, such as stress, emotions and environmental eating cues. Two-part multilevel modelling revealed that craving, availability of goal-incongruent foods, social eating cues, giving in to other temptations and weaker momentary intentions directly increased the risk and severity of goal-incongruent intake within the next 3 hr. Social cues, stress and craving further influence behaviour through altering intention implementation. Results imply that people regularly fail to implement intentions for 3-hr periods and that a range of factors influences this, both directly and by disrupting intentional processes. While for some barriers, fostering strong intentions throughout the day could be beneficial, others require different strategies for dietary adherence.

75 Examining the Role of Executive Functions on the Intention-Behavior Gap of Alcohol Harm Reduction Strategy Use

Objective:The Temporal Self-Regulation Theory (Hall and Fong, 2007) proposes that initiation and maintenance of effortful health behaviors relies on executive functions (EF: cognitive abilities associated with goal-directed behavior). Alcohol harm reduction strategies are health behaviors that aim to minimize the likelihood or severity of consequences associated with alcohol use. Some drinkers have the intention to drink safely but lack the ability to effectively initiate and execute the harm reduction behaviors. Executive functions may be one mechanism that helps explain the gap between safe drinking intentions and behavior. Specific components of EF may be differentially associated with alcohol harm reduction strategy use; working memory and set-shifting may be especially important in planning and following through with alcohol harm reduction strategies, and individuals with greater working memory capacity and set-shifting abilities may be more successful in implementing strategies that require preplanning and have a focus on altering typical the manner of drinking (e.g., not mixing types of alcohol). Inhibition may be important for resisting temptations that are inconsistent with safe drinking goals, and those with stronger inhibitory control may be more likely to follow through with strategies that require withholding responses despite desire to engage in the behavior, such as stopping or limiting drinking (e.g., not exceeding a predetermined number of drinks).Participants and Methods:Using ecological momentary assessment, the current study explored the extent to which an intention-behavior gap in harm reduction strategy use exists among college student drinkers (n=77), and investigated how potential individual differences in EF (i.e., working memory, set-shifting, and inhibition) were associated with translating intentions of drinking safely into action. Daily monitoring assessments contained brief measures of intention to use harm reduction strategies, actual strategy use, and alcohol-related behaviors, and were assessed daily for twenty-one days.Results:Multilevel model analyses revealed that although intention to use strategies predicted actual strategy use, measures of EF did not significantly moderate the relationship. Exploratory analyses indicated that set-shifting significantly moderated the intention-behavior gap for a subset of harm reduction strategies that relies more heavily on modifying behavior during a drinking event. Set-shifting did not significantly moderate the intention-behavior gap for a subset of strategies that relies more heavily on pre-planning before the drinking event.Conclusions:Findings from the current study suggests that those who plan to use strategies typically follow through regardless of individual differences in EF. Efforts to increase intention to drink safely can be incorporated into existing alcohol prevention and intervention programs, which would likely lead to increased use of harm reduction strategies and decreased alcohol-related consequences.

Time Perspective, Dietary Behavior, and Glycemic Control in Patients With Type 2 Diabetes.

Dietary behavior is a key component in the self-management of patients with Type 2 diabetes (T2DM), as it is essential for glycemic control and preventing diabetic complications. However, it is challenging for patients with diabetes to make sustainable dietary behavior changes and achieve long-term optimal glycemic control. Dietary behavior changes involve present efforts to achieve future benefits. The primary aim of this study was to investigate the relationships among time perspective, dietary behaviors, and health outcomes in patients with T2DM. Based on the temporal self-regulation theory and previous research, the secondary aim of the study was to explore how time perspective influences dietary behaviors. Following convenient sampling ( N = 329), a cross-sectional study was conducted in patients with T2DM between November 2021 and October 2022. Data were collected using self-reported questionnaires and the retrieval of clinical information from medical records. Hierarchical regression and path analysis were used to explore the relationships among study variables. Our analyses showed that a future-oriented time perspective was associated with better dietary behavior but was not significantly related to hemoglobin A1c. Hierarchical regression analysis also demonstrated that having a more future-oriented time perspective was associated with healthier dietary behavior after controlling covariates. Based on the theory and path analysis, there was an indirect effect of future time perspective on dietary behavior through self-control capacity and intention. The study reveals that a future-oriented time perspective can promote healthier dietary behavior when providing care for patients with T2DM. As a theoretical framework, the temporal self-regulation theory offers references for researchers and clinicians to take into consideration patients' time perspectives and their intentions and self-control capacity when developing interventional programs to improve dietary behaviors.

Executive functioning as a moderator of flossing behaviour among young adults: a temporal self-regulation theory perspective

ABSTRACT Background Flossing among young adults is often infrequent and barriers not completely understood. One explanation concerns the capacity for executive functioning (EF) during the self-regulation of behaviour. Methods Using Temporal Self-Regulation Theory (TST) as a framework to explore EF, young adults from Norwegian universities completed a survey that measured monthly flossing frequency, flossing-related intentions and behavioural prepotency (BP), and EF using the Behaviour Rating Inventory of Executive Function – Adult Version (BRIEF-A). Results Data from 362 participants were analysed. The TST-model explained a substantial proportion of variance in monthly flossing (R 2 = 0.74), and flossing was associated directly with intention and BP, and interactions between intention and both BP and global-EF. Sub-domains of EF were explored using the same model, revealing that behavioural regulation processes, specifically those related to emotional control and shifting between tasks, offered better fit. Simple slopes revealed that moderation effects were only present at lower levels of BP. Conclusion EF plays a role in moderating the translation of intentions into flossing behaviour. Specifically, emotional control and task-shifting appear to be influential, and this influence increases when habitual and environmental support (i.e. BP) is reduced. Overcoming EF-barriers may represent a key step in establishing flossing behaviours.

Predicting discretionary food consumption using temporal self-regulation theory and food reward sensitivity

Discretionary foods account for over a third of the average adult's total daily energy intake. But its excess consumption is a risk factor for obesity, Type 2 diabetes, and other diet-related diseases. This study aimed to use temporal self-regulation theory (intention, past behaviour, habit, self-regulatory capacity) and food reward sensitivity to identify predictors of discretionary food consumption. Two hundred and seventy-three participants aged between 18 and 80 (M = 42.55, SD = 17.07) comprising of mostly females (79.5%) and those residing in Australia (93.4%), completed a two-part online survey, one week apart. Participants completed measures of intention, past behaviour, habit, self-regulatory capacity, food reward sensitivity and demographic information at time one, and discretionary food consumption at time two. Data was analysed using a hierarchical multiple regression analysis. All variables in combination accounted for a significant 40.3% of the variance in discretionary food consumption (R2 = 0.40, p < .001). However, past behaviour and intention were the only unique significant predictors of discretionary food consumption. No significant moderation effects found. Findings offer insight into the motivators of discretionary food consumption, which can inform the development of effective interventions to reduce discretionary food consumption. Past behaviour should be considered, and intention targeted in interventions to reduce discretionary food consumption.

Applying the temporal self-regulation theory to understand sugar-sweetened beverage consumption among Chinese college students

ABSTRACT Objective Worldwide, there is a growing trend that college students are consuming more and more sugar-sweetened beverages (SSBs). In order to develop effective intervention strategies, it is important to explore what social-cognitive factors impact on college students’ SSB consumption. Building on the temporal self-regulation theory (TST), the current study aimed to examine the effects of intention, behavioral prepotency, and self-regulatory capacity on SSB consumption among college students. Design Data were collected from five hundred Chinese college students online. Participants self-reported their intention, behavioral prepotency (environmental cues and habits), self-regulatory capacity, and behaviors of SSB consumption. Results Study findings showed that intention, behavioral prepotency, and self-regulatory capacity accounted for 32.9% of variance in SSB consumption. In terms of the direct effects, intention, behavioral prepotency, and self-regulatory capacity were significantly associated with the SSB consumption among college students. In addition, self-regulatory capacity and habits but not the environmental cues showed significant moderation effects on the intention-SSB consumption path, indicating that individual factors rather than environmental cues influenced the intention-behavior path of SSB consumption among college students. Conclusion Findings of the current study demonstrated that the TST can be used to explain and understand the impacts of social-cognitive factors on college students’ SSB consumption. Future research can apply TST to develop effective intervention programs targeting the reduction of SSB consumption among college students.

A Study on the Localization of Urban Residents' Recreation: A Moderated Mediation Model Based on Temporal Self-Regulation Theory.

The pandemic has resulted in a further reduction in travel distance, recreational radius of destinations and other levels of tourism activity, making "local people traveling locally" a new feature. From the perspective of localization of urban residents' recreation, this paper describes a moderated mediation model based on temporal self-regulation theory. Five representative urban parks in Beijing were selected as study areas, and data collected through a questionnaire were used to discuss the behavioral characteristics of localized recreation and the formation mechanism of sense of place among urban residents in Beijing. The results showed that: (1) connectedness beliefs and temporal valuations positively influenced sense of place, and had a positive indirect effect on sense of place through the mediating role of recreation involvement; (2) recreation benefits positively influenced sense of place; (3) recreation benefits reinforced the direct and mediating role of recreation involvement. Based on these findings, the paper concludes with a discussion of the theoretical value and practical implications, as well as future research directions for park and city management.

Using an integrated model of the theory of planned behavior and the temporal self-regulation theory to explain physical activity in patients with coronary heart disease.

This study aimed to explore the psychosocial determinants of the physical activity (PA) levels in patients with coronary heart disease (CHD) using an integrated theoretical model based on the theory of planned behavior (TPB) and the temporal self-regulation theory (TST). This was a prospective study conducted at the Affiliated Hospital of Hangzhou Normal University, Zhejiang, China. A total of 279 patients with CHD [176 men aged 26-89 years, mean (M) = 64.69, standard deviation (SD) = 13.17] were selected under the study inclusion criteria by convenience sampling. The data on attitude, subjective norm (SN), perceived behavioral control (PBC), and intention variables for the TPB model and consideration of future consequences (CFC), habit, and self-control (SC) variables for the TST model were collected 1-2 days before the discharge (Time 1, T1) of the participants, and a telephone follow-up was made to assess the participants' self-reported PA levels 1 week after their discharge (Time 2, T2). The results revealed that only 39.8% of the patients with CHD met the guidelines' recommendations on PA. The data analyses using structural equation modeling (SEM) in the Mplus 8.3 modeling program showed that, in the simple mediation model, attitude, PBC, and CFC were positively related to the intention to practice guideline-recommended levels of PA but SN was not. In addition, intention was shown to mediate the relationships between attitude, PBC, CFC, and PA levels. Furthermore, based on the moderated mediating model, intention and habit were shown to be positively associated with PA levels but SC was not. Moreover, SC played a significant moderating role between intention and PA levels. However, habit strength did not moderate the relationship between intention and PA levels. An integration of the TPB and TST models offers a good theoretical tool for understanding PA levels in patients with CHD.

Utility of temporal self-regulation theory in health and social behaviours: A meta-analysis.

Temporal self-regulation theory was developed to address an observed intention-behaviour gap across behaviours. However, a synthesis of studies has not yet been conducted to investigate the theory's utility to explain behaviour and bridge the intention-behaviour gap. This review aimed to evaluate the predictive ability of temporal self-regulation theory to understanding behaviour and pre-registered at PROSPERO (ID: CRD42021253174). Forward citation searches on the original theory publication through Google Scholar until May 2021 identified 37 eligible articles, including, 12,555 participants assessing at least two of the three theory constructs. Random-effects meta-analyses assessed the strength of associations between theory constructs on behaviour and random effects meta-regressions assessed moderators of behaviour. Findings provide support for temporal self-regulation theory to explain behaviour with very weak (self-regulatory capacity r=.039, CI=.00, -.07) to moderate (intention r=.331, CI=.26, .40; behavioural pre-potency r=.379, CI=.32, .44) effect sizes. Further, the strength of associations varied across behaviour types and contexts. However, there was high heterogeneity across studies and some moderating effects could not be assessed due to insufficient numbers of studies assessing interactions. We urge researchers to assess and report interactions for better understanding of the drivers of behaviour to develop effective interventions for positive behaviour change.

Can temporal self-regulation theory and its constructs predict medication adherence? A systematic review and meta-analysis

ABSTRACT The relationships between temporal self-regulation theory (TST) constructs (intention, behavioural prepotency and self-regulatory capacity) and medication adherence should be established before further applying the theory to adherence. Searches of PsychINFO, Medline, EMBASE, CINAHL and Web of Science were conducted in 2019 (updated November 2021). Studies had to be original quantitative research, assessed the relationship between one of the constructs and adherence in one illness, and used an adult population. The risk of bias was assessed using the NHLBI Quality Assessment Tool for Observational Cohort and Cross-Sectional Studies. Three meta-analyses were conducted using R. Moderation analyses were also conducted. A total of 57 articles (60 studies) with 13,995 participants were included, with 7 studies included in more than one analysis. Results identified significant correlations between intention (r = .369, [95% CI: .25, .48]), behavioural prepotency (r = .332, [95% CI: .18, .48]), self-regulatory capacity (r = .213, [95% CI: .10, .32]) and adherence. There was some evidence of publication bias and no significant moderators. No studies explored the interactions in the theory, so whilst the constructs adequately predict adherence, future research should apply the theory to adherence in a specific illness to assess these relationships.

Future Time Perspective and Bedtime Procrastination: The Mediating Role of Dual-Mode Self-Control and Problematic Smartphone Use.

This study examined bedtime procrastination predictors and the development process concerning health behavior. Based on temporal self-regulation theory and the self-regulatory framework of time perspective, we examined the effects of future time perspective, dual-model of self-control, and problematic smartphone use on bedtime procrastination. Further, including the mediating role of dual-mode self-control and problematic smartphone use in the effects of future time perspective on bedtime procrastination among 3687 participants (38.73% male; Mage = 16.17 years, SD = 2.42, range = 11–23) Chinese students. The results showed that the future time perspective, dual-mode self-control, and problematic smartphone use had significant predictive effects on bedtime procrastination. Importantly, the negative effect of future time perspective on bedtime procrastination is mediated by the impulse system, control system, and problematic smartphone use separately and serially mediated by the impulse system and problematic smartphone use, rather than the control system and problematic smartphone use; these findings extend previous research on the contributing factors of bedtime procrastination and provide an empirical basis for promoting people to form healthy sleep habits.

Adaptive Text Messaging for Postpartum Risky Drinking: Conceptual Model and Protocol for an Ecological Momentary Assessment Study.

BackgroundRisky drinking is prevalent among women of childbearing age. Although many women reduce their drinking during pregnancy, more than half return to prepregnancy levels during the early postpartum period. Risky drinking in new mothers may be associated with negative child and maternal health outcomes; however, new mothers are unlikely to seek treatment for risky drinking because of stigma and fear of child protective service involvement. SMS text messaging is a promising approach for reaching non–treatment-seeking new mothers at risk because of risky drinking. SMS text messaging interventions (TMIs) are empirically supported for alcohol use, but a tailored intervention for new mothers does not exist. This study aims to fill this gap by developing a just-in-time adaptive TMI for postpartum risky drinking.ObjectiveThe objectives of this paper are to present a preliminary conceptual model of postpartum risky drinking and describe the protocol for conducting an ecological momentary assessment (EMA) study with new mothers to inform the refinement of the conceptual model and development of the TMI.MethodsThis paper presents a preliminary conceptual model of postpartum risky drinking based on the motivational model of alcohol use, social cognitive theory, and temporal self-regulation theory. The model proposes three primary intervention targets: motivation, self-efficacy, and self-regulation. Theoretical and empirical literature in support of the conceptual model is described. The paper also describes procedures for a study that will collect EMA data from 30 participants recruited via social media and the perinatal Central Intake system of New Jersey. Following the baseline assessment, EMA surveys will be sent 5 times per day for 14 days. The assessment instruments and data analysis procedures are described.ResultsRecruitment is scheduled to begin in January 2022 and is anticipated to conclude in March 2022. Study results are estimated to be published in July 2022.ConclusionsThe study findings will enhance our understanding of daily and momentary fluctuations in risk and protective factors for risky drinking during the early postpartum period. The findings will be used to refine the conceptual model and inform the development of the TMI. The next steps for this work include the development of intervention components via an iterative participatory design process and testing of the resulting intervention in a pilot microrandomized trial.International Registered Report Identifier (IRRID)PRR1-10.2196/36849

The role of environmental cues in sugar-sweetened beverage consumption using a temporal self-regulation theory framework

Sugar-sweetened beverage consumption is related to adverse health outcomes such as obesity and Type 2 diabetes. The present research further examined the utility of the temporal self-regulation theory in predicting sugar-sweetened beverage consumption. In addition, the research aimed to identify salient cues that trigger intake. Two-hundred and eighty-seven participants were recruited using convenience sampling in US and Australian populations. Hierarchical multiple regression analyses were used, and the final model accounted for 27.1% of the variance in consumption, providing partial support for the temporal self-regulation theory (ƒ2 = 0.37). Intention accounted for a significant 7.0% of variance (R2 = 0.07, p < .001), behavioural prepotency variables (past behaviour, habit, and cues) together combined for an additional 15.1% of variance (R2 = 0.15, p < .001), but neither measure of self-regulatory capacity (trait self-control, inhibition) was a significant predictor. No cues emerged as unique predictors, however the findings suggest that consumption may be influenced by a combination of cues across different situations. Behavioural prepotency moderated the intention-behaviour relationship such that as behavioural prepotency increased, the greater the influence intention had on behaviour. Further support for the role of both intention and automatic processes in sugar-sweetened beverage consumption was garnered, but more research is needed to identify when specific cues influence consumption most.

Applying temporal self-regulation theory to identify correlates of soft plastic recycling in Australia

ABSTRACT Objective Rigid plastics are accepted by Australian recycling facilities but soft forms are not. Further, single-use soft plastic may only be used once but can take 400 years to break down. As only 12% of plastic is recycled, increasing recycling of soft plastic will decrease negative environmental impacts. This study aims to assess the applicability of temporal self-regulation theory to identify factors that correlated with soft plastic recycling. Method Participants (N = 318) completed a cross-sectional online questionnaire measuring connectedness beliefs, temporal valuations, intention, habit, self-control and behaviour. Results Connectedness beliefs and temporal valuations accounted for significant variance in intention (R2 = .13, p < .001). Intention and habit accounted for significant variance in behaviour (R2 = .39, p < .001). Habit at low levels moderated the relationship between intention and behaviour but self-control was not a significant moderator between intention and behaviour. Conclusions Findings provide partial support for temporal self-regulation theory to assess a pro-environmental behaviour. Collecting soft plastic for recycling is largely explained by habit and intention. Moderating effects suggest that strong habit may compensate for weaker intention to carry out the behaviour and vice-versa. Results indicate potential for transferability of the theory for other areas of behavioural research and can inform interventions to encourage soft plastic recycling. KEY POINTS What is already known about this topic: (1) When used to predict environmental behaviours the theory of planned behaviour has shown good predictive ability but also an intention behaviour gap. (2) Temporal self-regulation theory is used to explain and predict health behaviours and has been successful in closing the observed intention-behaviour gap in the theory of planned behaviour, a key theory in the field. (3) There is a need to effectively recycle soft plastic due to the global increase in plastic pollution and high soft plastic production rates but lack of infrastructure and knowledge regarding how to recycle soft plastic, potentially contributing to overall low plastic recycling rates. What this topic adds: (1) This study is the first to apply temporal self-regulation theory to environmental psychology with partial support for the theory in explaining behaviour. This suggests that temporal self-regulation theory may have utility in environmental psychology. (2) This study explains variance in recycling behaviour and demonstrates ways researchers could intervene to change behaviour. (3) This study is the first to investigate soft plastic recycling behaviour and has identified some of its correlates and directions for future research, which can inform knowledge and interventions to increase rates.

운동 의도가 의도-행동 불일치에 미치는 영향에서 자기조절능력 및 자기통제의 조절효과

Purpose: The first purpose of this study is to investigate the differences in the timing of recognition of benefits and costs for exercise depending on the level of exercise behavior. Also the second purpose is to ensure the self regulatory capacity and self control have moderating effects on the relationship between exercise intention and intention-behavior gap. Methods: 100 women whose age are 20s were recruited for the research participants. The group of contemplation, preparation, action, maintenance were formed based on the Transtheoretical model, with 25 participants per group. Data were collected from 3 cognitive tests, questionnaires and text messages. Result: First, it has been shown that all groups are aware of the costs for exercise before the benefits. However, the recognition of benefits for exercise in the maintenance group was faster than in the preparation group. The temporal disjunction between benefits and costs was shown to be small in the maintenance group. Second, the exercise intention has a significant negative effect on intention- behavior gap. That is, the higher the intention, the lower the intention-behavior gap. Third, the reaction time on incongruent condition of the Stroop test, total move score and initial time of the Tower of London have moderating effects on the relationship between exercise intention and intention-behavior gap. Fourth, sub-factors of self control did not show any moderating effects on the relationship between exercise intention and intention-behavior gap. Conclusion: Temporal Self-Regulation Theory was partially validated through this paper. These results suggest that an individual’s executive function could be a significant variable to predict exercise intention - behavior gap on exercise.

Understanding the predictors of hand hygiene using aspects of the theory of planned behaviour and temporal self-regulation theory

Objective Adherence to proper hand hygiene practice is relatively low and is particularly salient in light of the current COVID-19 pandemic. Having a greater understanding of the psychosocial predictors of engaging in proper hand hygiene is warranted. One way to do this is through the application of a combined theory of planned behaviour and temporal self-regulation theory model. Design A prospective two-part study was conducted between May – November 2020, with N = 232 Australians. At time one, variables from both the theory of planned behaviour (attitude, subjective norm, perceived behavioural control, and intention) and temporal self-regulation theory (habit, environmental cues, and planning) were completed. Main outcome measures One week later, engagement in proper hand hygiene behaviour over the previous week was assessed. Results Two hierarchical multiple regressions were conducted, with 47% of variance accounted for in intention, with subjective norm being the strongest predictor, and 38% of variance accounted for in hand hygiene behaviour, with intention being the strongest predictor. Environmental cues also moderated the relationship between intention and behaviour. Conclusions To increase intention, incorporating subjective norm messages in advertisements may be helpful. Incorporating environmental cues in places where hand washing is recommended may assist in increasing hand hygiene.

Stable and momentary psychosocial correlates of everyday smoking: An application of Temporal Self-Regulation Theory

Smoking is one of the leading causes of non-communicable disease mortality and morbidity. Smoking behaviour is determined by both stable, person-level (e.g., motivation, nicotine dependence) and variable, situation-level factors (e.g., urges, cues). However, most theoretical approaches to understanding health behaviours so far have not integrated these two spheres of influence. Temporal Self-Regulation Theory (TST) integrates these person-level and situation-level factors, but has not yet been comprehensively applied to predicting smoking behaviour. We use Ecological Momentary Assessment to examine the utility of TST in predicting daily smoking. 46 smokers reported individual and environmental cues right after smoking and at random time points during the day. Cognitions, self-control, past behaviour, and nicotine dependence were assessed at baseline. Multi-level logistic regressions show that smoking is largely guided by momentary cues, but individual motivation can buffer their influence. This suggests that TST is a useful integrative approach to understand modifiable determinants of smoking and thus intervention targets.

Effectiveness of a nurse-led temporal self-regulation theory-based program on heart failure self-care: A randomized controlled trial

BackgroundHeart failure self-care is crucial for sustainable heart failure management but its adherence remains poor worldwide. Despite having an intention to change, individuals often face difficulties in modifying existing lifestyle habits and sustaining change motivations. ObjectivesTo examine the effectiveness of a novel theory-driven nurse-led self-regulation program on improving heart failure self-care behaviours, future-thinking and behavioural automaticity. DesignA two-arm randomized controlled trial. Settings & Participants144 patients with heart failure were recruited from September 2018 to July 2019 at a tertiary hospital in Singapore. MethodsParticipants were randomly assigned to a self-regulation intervention (n = 72) or usual care group (n = 72). The three-month intervention was developed based on the temporal self-regulation theory and consisted of one face-to-face session, a print booklet and three reinforcement telephone follow-ups at week 3, 6 and 9. Outcomes were measured at baseline (T0), immediate after a three-month intervention (T1) and a further three-month follow-up (T2). heart failure self-care was measured using the Self-Care of Heart Failure Index (SCHFI) maintenance subscale, future-thinking was measured using the Consideration of Future Consequences Scale (CFCS) and behaviour automaticity was measured using the Self-Reported Behavioural Automaticity Index (SRBAI). The outcomes were compared between groups by using generalized estimating equations (GEE) based on intention-to-treat principle. ResultsNo significant differences were found between the groups at baseline except for age. Participants were on average 61 years old, men (79.2%), had mild heart failure symptoms (50.7%) and had three comorbidities (66.0% dyslipidaemia; 65.3% hypertension; 61.8% history of myocardial infarction). Baseline scores indicated poor heart failure self-care (52.9±17.2, cut off ≥70). GEE results showed significantly higher heart failure self-care improvements in intervention group than control group at both T1 (regression coefficient, B = 13.9, 95% CI: 8.02 to 19.9, p < 0.001) and T2 (B = 8.34, 95% CI: 1.68 to 15.0, p = 0.014) after adjusting for gender, living alone, education level, comorbidity and age. Results also showed significantly higher increase in future-thinking (B[95% CI]=0.694[.123, 1.26], p = 0.017) and behaviour automaticity (B[95% CI]=0.656[.085, 1.23], p = 0.024) at T1 and only increase in behaviour automaticity (B[95% CI]=0.674[.099, 1.25], p = 0.022) at T2. However, only the differences in self-care scores at T1 remained significant after Bonferroni correction. No significant differences were found for intention, quality of life and clinical biomarkers. ConclusionsThe program was effective in improving heart failure self-care and has potential for clinical implementation and generalisation to other chronic illnesses. Longer follow-up study is needed to uncover its long-term benefits on clinical outcomes.

Investigating mechanisms for recruiting and retaining volunteers: The role of habit strength and planning in volunteering engagement

ABSTRACT Volunteering rates in high-income countries are declining. Most research into understanding volunteering engagement has focused on conscious processes (e.g., motives), with little exploration of non-conscious antecedents of volunteering engagement. Adopting a new line of investigation, this research used temporal self-regulation theory to investigate the influence of both rational and automatic processes on volunteering engagement. Two related studies using different methodologies were conducted to investigate the influence of intention, planning, and habit strength on volunteering engagement. In both studies, intention and habit strength were significant predictors of volunteering engagement, with planning only significantly predicting volunteering engagement in Study 1. It was also found, in Study 2, that habit strength moderated the intention–behavior relationship. These findings highlight that both rational and automatic processes play a part in volunteering engagement and have implications for recruiting and retaining volunteers.
