The contribution and interplay of implicit and explicit processes on physical activity behavior: empirical testing of the physical activity adoption and maintenance (PAAM) model.

The adoption and maintenance of physical activity (PA) is an important health behavior. This paper presents the first comprehensive empirical test of the Physical Activity Adoption and Maintenance (PAAM) model, which proposes that a combination of explicit (e.g., intention) and implicit (e.g., habit,, affect) self-regulatory processes is involved in PA adoption and maintenance. Data were collected via online questionnaires in English, German, and Italian at two measurement points four weeks apart. The study included 422 participants (Mage= 25.3, SDage= 10.1; 74.2% women) from Germany, Switzerland, Italy, Canada, and the U.S. The study results largely supported the assumptions of the PAAM model, indicating that intentions and habits significantly mediate the effects of past PA on future PA. In addition, the effect of past PA on future PA was shown to be significant through a mediation chain involving affect and habit. Although the hypothesis that trait self-regulation moderates the intention-behavior relationship was not supported, a significant moderating effect of affect on the same relationship was observed. The results suggest that interventions targeting both explicit and implicit processes may be effective in promoting PA adoption and maintenance.

Fear of Falling Carries Over into Overprotection in Old Age: A Cross-Lagged Panel Analysis.

Fear of falling might result in overprotection by one's social environment. In turn, feeling dependent could increase fear of falling. However, the association between fear of falling and perceived overprotection and its temporal order is unknown. This longitudinal study explores this potential mutual longitudinal association. This study presents secondary analyses from a larger trial. We tested the association between fear of falling and perceived overprotection in a cross-lagged path model controlled for falls, health-related quality of life, age, gender, and trial condition. N = 310 participants (M = 70 years, range: 64-92) completed self-reports at Time 1, 7 (Time 2), and 11 weeks (Time 3) after baseline assessment. We found a positive association from fear of falling to perceived overprotection (ß = .12, 95% CI[0.02, 0.21], p = .02; ß = .10; [0.01, 0.18], p = .03). The reversed cross-lagged paths were not significant. Findings suggest higher fear of falling translates into perceived overprotection, which may in turn increase loss of independence in old age.

Associations Between Implicit and Explicit Condom Use Measures With Condom Use Barriers: Relationships Make A Difference.

OBJECTIVE: The association between explicit and implicit psychological measures might be affected by the similarity of the assessment method and by the overlap of the components of the constructs being assessed. This study examined the association between condom use barriers and explicit and implicit measurements of condom use and the moderating role of sexual intercourse in these associations. DESIGN: This was a cross sectional correlational study. An analysis of baseline data from a randomized controlled trial including 149 university students was included. MAIN MEASURES: These included a questionnaire assessing condom use barriers, an implicit condom use test (a structured semi-projective test), and an explicit condom use question. Hierarchical regressions and correlations were examined in the full sample and by groups of participants with and without sexual intercourse. RESULTS: In those without sexual intercourse, all barriers sub-scales were significantly and negatively correlated with implicit condom use and unrelated to explicit condom use. In contrast, among those engaged in sexual intercourse, barriers were significantly and negatively correlated with the explicit condom use measure, and only barriers concerning partner and motivation correlated with implicit condom use tendencies. CONCLUSION: Having a sexual partner plays a major role in the relations between barriers and implicit and explicit condom use measures. The pattern of the results is discussed in relation to cognitive and social factors.

Changes in Psychological Determinants of Behavior Change after Individual versus Group-Based Lifestyle-integrated Fall Prevention: Results from the LiFE-is-LiFE Trial.

OBJECTIVE: The Lifestyle-integrated Functional Exercise (LiFE) intervention has been shown to promote physical activity in fall-prone older adults. However, the underlying mechanisms of how LiFE functions remain unclear. This study compares the effects of the individual and group-based LiFE formats on psychological determinants of behavior change derived from the health action process approach, habit formation theory, and self-determination theory. METHODS: Secondary analysis on basis of the randomized, non-inferiority LiFE-is-LiFE trial were performed. Questionnaire data on psychological determinants were obtained from older adults (M = 78.8 years, range 70-95) who took part in either the individual (n = 156) or the group-based (n = 153) LiFE intervention. Measurement points varied from three to six times, and from baseline (T1) up to a 12-month follow-up (T6). A generalized linear mixed model was specified for each determinant. RESULTS: Both LiFE and gLiFE participants reported lower levels of motivational determinants at T6. LiFE participants showed significantly higher values of action planning and coping planning at T6. Participants in both formats showed increased levels of action control at T6, whereas participants' habit strength decreased post-intervention but then stabilized over time. LiFE participants showed higher levels of autonomy, competence, and relatedness throughout the study, but levels of intrinsic motivation did not differ between formats and from T1 to T6. CONCLUSION: In both formats, but especially in the individual LiFE, the behavior change techniques used affected volitional rather than motivational or general determinants of behavior change. Habit strength as an important indicator of the sustainability of the LiFE exercises stabilized over time, indicating that participants, at least partly, sustained their formed habits long-term.

Study protocol for the description and evaluation of the "Habit Coach" - a longitudinal multicenter mHealth intervention for healthy habit formation in health care professionals.

BACKGROUND: The adoption of a healthy lifestyle plays a crucial role for the health and well-being of health care professionals. Previous e- and mHealth interventions relied on deliberative psychological processes (e.g., intention, planning) to target lifestyle changes, while revealing mixed efficacy. The additional potential of non-deliberative, automatic processes (i.e., habits) for behavior change has been understudied in interventions so far. The Habit Coach mHealth intervention combines deliberative and non-deliberative processes to support health care professionals in forming healthy physical activity, nutrition and mindfulness habits in daily life. The aim of this paper is to outline the study protocol including a detailed description of the mHealth intervention, evaluation plan, and study design. The purpose of this trial is to understand healthy habit formation in health care professionals over time. METHODS: A one-arm, multicenter mHealth intervention study will be conducted. Behavioral and psychosocial predictors will be collected via within-app questionnaires across a 100-day period at baseline, post, as well as at weekly assessments. To understand habit formation across time, linear mixed models will be used. DISCUSSION: This trial aims to unravel the role of motivational and volitional determinants for healthy habit formation across multiple health behaviors in health care professionals embedded in a mHealth intervention. TRIAL REGISTRATION: This trial is registered in the German Clinical Trials Register, DRKS-ID DRKS00027156. Date of registration 17 November 2021.

What helps to form a healthy nutrition habit? Daily associations of intrinsic reward, anticipated regret, and self-efficacy with automaticity.

BACKGROUND: High automaticity in healthy nutrition behaviors is related to long-term maintenance of these behaviors. Drawing upon theoretical frameworks of habit formation, proposed antecedents such as intrinsic reward, anticipated regret, and self-efficacy are important correlates of automaticity, but not much is known about their day-by-day relationships with automaticity in healthy nutrition behaviors. This study tested previous-day within-person (i.e., from one day to the next) and same-day within-person associations of intrinsic reward, anticipated regret, and self-efficacy with automaticity of a healthy nutrition behavior, for which participants attempted to form a new habit. METHODS: Secondary analyses of a randomized controlled trial with two planning intervention conditions including a longitudinal sample of n = 135 participants (age: M = 24.82 years; SD = 7.27) are reported. Participants formed a plan on a self-selected healthy nutrition behavior to become a new habit and were followed up over 12 weeks assessing daily levels of plan-specific intrinsic reward, anticipated regret, self-efficacy, and automaticity. Lagged multilevel models with 84 study days nested in participants estimated previous-day within-person, same-day within-person, and between-person relationships of intrinsic reward, anticipated regret, and self-efficacy with automaticity. FINDINGS: Regarding within-level relationships, higher-than-usual levels of intrinsic reward, anticipated regret, and self-efficacy of the same day but not of the previous day were associated with higher within-person automaticity. With respect to between-level relationships, higher between-levels (i.e., higher person mean levels across the study period) of intrinsic reward, anticipated regret, and self-efficacy were linked with higher automaticity. DISCUSSION: Findings point towards the potential to intervene on intrinsic reward, anticipated regret, and self-efficacy when aiming to promote a new healthy nutrition habit.

Determinants of implementing reablement into research or practice: A concept mapping study.

PURPOSE: Reablement is a health and social model of care gaining international prominence. It is included in some publicly funded healthcare systems in Australia, Canada, United Kingdom, Norway, Sweden and other European countries. To advance reablement research and practice, we aimed to synthesize expert opinion on opportunities and challenges to delivering care with this model. METHODS: We invited authors of reablement publications and other experts from the field to take part in a three-step online concept mapping exercise: (i) brainstorming statements based on a focus prompt; followed by (ii) sorting and (iii) rating statements. We invited 63 participants, of whom 19 participants generated 114 statements. Two authors reviewed each statement independently then met three times to determine one main idea/statement and removed unrelated or duplicate ideas. The research team used concept mapping software and online and email discussion to generate clusters or groups of determinants. RESULTS: There were 58 statements for sorting and rating; 11 and 12 participants completed the sorting and rating steps, respectively. The five clusters were person and caregiver elements for participation; key reablement components for success; reablement content and delivery; organizational factors; and provider beliefs and training. Statements rated as both highly important and feasible to implement into practice were generally captured under the domains of goal setting and pursuit and person-centred care. CONCLUSION: These results generate hypotheses for future research and practice in reablement for older adults.

Exploring behavior change techniques for reablement: A scoping review.

BACKGROUND: Reablement is a team-based person-centered health and social care model, most commonly available for community-dwelling older adults. Understanding the components of reablement and how it is delivered, received, and enacted facilitates best evidence and practice. Determining behavior change techniques (BCTs) or strategies is an important step to operationalize implementation of reablement. OBJECTIVE: We conducted a scoping review of peer-reviewed literature to identify BCTs used within reablement studies. METHODS: We registered our study with the Joanna Briggs Institute and conducted five database searches. Inclusion criteria were peer-reviewed studies focused on adults and older adults without significant cognitive impairment or dementia receiving reablement, and all study designs, years, and languages. We excluded studies focused on reablement for people with dementia or reablement training programs. The last search was on April 8, 2021. Two authors screened independently at Level 1 (title and abstract) and 2 (full text). Two authors adjudicated BCTs for each study, and a third author confirmed the final list. RESULTS: We identified 567 studies (591 publications) and included 21 studies (44 publications) from six global locations. We identified 27 different BCTs across all studies. The three most common BCTs for reablement were goal setting (behavior), social support (unspecified), and instruction on how to perform a behavior. CONCLUSIONS: We highlight some behavioral components of reablement and encourage detailed reporting to increase transparency and replication of the intervention. Future research should explore effective BCTs (or combinations of) to include within reablement to support health behavior adoption and maintenance.

What makes implementation intentions (in)effective for physical activity among older adults?

OBJECTIVES: For most populations, implementation intentions (IIs) facilitate physical activity (PA). However, for older adults, previous studies found mixed evidence for the effectiveness of this behaviour change technique. To examine which characteristics of IIs predict successful enactment, the content of older participants' IIs formed within a self-regulatory intervention to prompt PA was analysed. DESIGN: A sample of N = 126 German speaking adults aged 64 and older formed up to six IIs for PA and reported their enactment 5 weeks later. METHODS: Controlling for age and sex, multilevel models tested associations between characteristics of IIs (e.g., chronological rank of II, hetero- and homogeneity, specificity, presence of certain cues) and enactment. RESULTS: Significantly related to enactment were: the chronological rank of an II (first IIs superior to last IIs), greater heterogeneity in activities, greater specificity of when-cues, and greater use of pre-existing routines. CONCLUSIONS: Participants were more likely to enact their IIs 5 weeks later if they planned different (heterogeneous) activities, created IIs with more specific when-cues (e.g., on Monday at 9 am), and in particular a routine (e.g., after breakfast). They also enacted the first three IIs (chronological rank of II) more often than the last three IIs. Future experimental studies should test whether providing instructions to create IIs based on the above significant characteristics lead to more effective health behaviour change among older adults.

Perceived Physical Functioning and Gait Speed as Mediators in the Association Between Fear of Falling and Quality of Life in Old Age.

Preserving Quality of Life (QoL) in old age gains in importance, but Fear of Falling (FoF) considerably limits QoL. The aim of our study was to understand how physical mediators may translate FoF to QoL. At Time 1, FoF, subjective leg strength, balance, QoL, and objective gait speed were assessed. QoL was reassessed after 6 months, at Time 2 (n = 125). A sequential mediation analysis examined whether the relationship between FoF and QoL could be mediated by leg strength, balance, and gait speed. FoF was directly associated with QoL (ß = -.27; 95% CI [-0.007, -0.001]) as well as indirectly via leg strength, balance, and gait speed (specific sequential indirect effect: ß = -.03; 95% CI [-0.06, -0.001]; R2 = .40 in QoL; controlled for age, QoL at Time 1). An intervention approach could be to address FoF and foster physical functioning and gait speed to maintain QoL.

Hand Washing and Related Cognitions Following a Brief Behavior Change Intervention During the COVID-19 Pandemic: a Pre-Post Analysis.

BACKGROUND: Effective hand washing (for at least 20 s, with water and soap) is one of the health behaviors protecting against infection transmissions. Behavior change interventions supporting the initiation and maintenance of hand washing are crucial to prevent infection transmissions. Based on the Health Action Process Approach, the aim of this research was to conduct a pre-post analysis of hand washing and related cognitions (i.e., intention, self-efficacy, self-monitoring), measured up to 100 days following an intervention. METHODS: A convenience sample of N = 123 participants (age: M = 23.96 years; SD = 5.82; 80% women) received a brief intervention (key behavior change techniques: information about health consequences of hand washing; action planning) and responded to daily diaries and questionnaires up to a 100-day follow-up. Two-level models were used to analyze data of n = 89 participants who provided longitudinal data. RESULTS: Hand washing and self-monitoring increased, whereas intention and self-efficacy decreased over time. Only self-monitoring was a consistent positive correlate of hand washing on a between-person level. CONCLUSIONS: Hand washing and self-monitoring considerably increased over several weeks following the intervention. Future research testing the intervention against a control condition is needed to rule out that changes in behavior and cognitions might have been prompted by completing the daily diaries.

Defining and implementing patient-centered care: An umbrella review.

OBJECTIVES: Patient- or person-centered care (PCC) integrates people's preferences, values, and beliefs into health decision-making. Gaps exist for defining and implementing PCC; therefore, we aimed to identify core elements of PCC and synthesize implementation facilitators and barriers. METHODS: We conducted an overview of systematic reviews (umbrella review) and included peer-reviewed literature for adults in community/primary care settings. Two reviewers independently screened at Level 1 and 2, extracted data and appraised the quality of reviews. Three reviewers conducted a thematic analysis, and we present a narrative synthesis of findings. RESULTS: There were 2371 citations screened, and 10 systematic reviews included. We identified 10 PCC definitions with common elements, such as patient empowerment, patient individuality, and a biopsychosocial approach. Implementation factors focused on communication, training healthcare providers, and organizational structure. CONCLUSIONS: We provide a synthesis of key PCC elements to include in a future definition, and an overview of elements to consider for implementing PCC into practice. We extend existing literature by identifying clinician empowerment and culture change at the systems-level as two future areas to prioritize to enable routine integration of PCC into practice. PRACTICE IMPLICATIONS: Findings may be useful for researchers and or health providers delivering and evaluating PCC.

Physical Activity and Bone Health in Men: A Systematic Review and Meta-Analysis.

BACKGROUND: Research on osteoporosis and physical activity often focuses on women. We aimed to conduct a systematic review to assess the benefits and harms of physical activity interventions for men's bone health. METHODS: We used standard methods and searched for randomized controlled trials (RCTs) (duration, ≥6 months) published in all languages across multiple databases and trial registries. The last search was conducted on July 22, 2020. RESULTS: We included 11 studies (14 publications), resulting in a sample of N=723 men (range, 17-132 participants). We found low-certainty evidence that physical activity has little influence on the areal bone mineral density (aBMD) at the total hip (5 RCTs, N=324; mean difference [MD], 0.03 [95 confidence interval (CI), 0.01 to 0.05]) and little or no influence on the aBMD at the femoral neck (3 RCTs, N=186; MD, 0.00 [95% CI, -0.04 to 0.04]), lumbar spine (3 RCTs; N=213; MD, 0.05 [95% CI, -0.01 to 0.11]), and whole body (4 RCTs, N=203; MD, -0.00 [95% CI, -0.03 to 0.02]). CONCLUSIONS: We found low-certainty evidence that physical activity (≥6 months) has some effect on the total hip in men, but new evidence may change this finding. This review highlights the gap in the evidence on specific intervention prescriptions that can benefit the bone geometry, structure, microarchitecture, and, ultimately, bone strength in men. Future research should engage in comprehensive reporting of harms, quality of life outcomes, advanced imaging findings, and long-term interventions.

Applying Social Cognition Models to Explain Walking Duration in Older Adults: The Role of Intrinsic Motivation.

This study examined the applicability of the health action process approach (HAPA) to walking duration in older adults and the added value of extending the HAPA by intrinsic motivation. Self-reports from older adults (N = 309; Mage = 78.7, 70-95 years) regarding activity-related intrinsic motivation and HAPA variables were collected at the baseline of a fall prevention intervention study. Walking duration at ≥3 metabolic equivalents of task was measured for 7 days via body-worn accelerometers. Two structural equation models with walking duration as a manifest outcome were specified. In both models, the model fit was acceptable, but intention and planning were not associated with walking duration. Intrinsic motivation was significantly related to most HAPA variables and walking duration. Variance explained for walking duration was R2 = .14 in the HAPA and R2 = .17 in the extended model. For explaining older adults' walking duration, intrinsic motivation, but not HAPA-based intention and planning, seemed to be important.

Habit formation following routine-based versus time-based cue planning: A randomized controlled trial.

OBJECTIVES: Habit formation has been identified as one of the key determinants of behaviour change. To initiate habit formation, self-regulation interventions can support individuals to form a cue-behaviour plan and to repeatedly enact the plan in the same context. This randomized controlled trial aimed to model habit formation of an everyday nutrition behaviour and examined whether habit formation and plan enactment differ when individuals plan to enact their behaviour in response to a routine-based versus time-based cue. DESIGN: Following a baseline assessment, N = 192 adults (aged 18-77 years) were randomly assigned to a routine-based cue or a time-based cue planning intervention, in which they selected an everyday nutrition behaviour and linked it to a daily routine or a time cue. METHODS: Participants responded to daily questionnaires over 84 days assessing plan enactment and the behaviour's automaticity (as an indicator of habit formation). Multilevel models with days nested in participants were fitted. RESULTS: As indicated by asymptotic curves, it took a median of 59 days for participants who successfully formed habits to reach peak automaticity. Group-level analyses revealed that both routine-based and time-based cue planning led to increases in automaticity and plan enactment, but no between-condition differences were found. Repeated plan enactment was a key predictor for automaticity. CONCLUSIONS: Linking one's nutrition behaviour to a daily routine or a specific time was similarly effective for habit formation. Interventions should encourage persons to repeatedly carry out their planned behaviour in response to the planned cue to facilitate habit formation.

The effects of psychological inoculation on condom use tendencies and barriers; a randomized controlled trial.

OBJECTIVE: Condom use prevents the contraction of the HIV. Research shows limited effects of education on increasing condom use. Psychological inoculation (PI) has been found to be more effective in this domain, however, its mechanism is unknown. This study examined effects of PI versus education on condom use barriers and tendencies, and its relations with cognitive dissonance, using a fully automatized online system. DESIGN: The study was a randomized controlled trial (RCT) and included 149 students from a German University randomly assigned to PI or a control condition. MAIN OUTCOME MEASURES: An indirect condom use test (I-CUTE), a condom use barriers questionnaire, self-reported condom use, and cognitive dissonance estimations were all assessed at baseline and one-month post-intervention. RESULTS: PI significantly increased I-CUTE scores when participants had sexual relations. Control participants increased in self-reported condom use and on I-CUTE scores in people without sexual relations. No changes in barriers were seen in either group. The cognitive dissonance tended to be higher in PI participants as compared to control participants. CONCLUSIONS: PI increases I-CUTE scores compared to controls (based on effect sizes), and significantly in those with sexual relations. The role of relationship status and the mechanisms of PI should be further examined.

Social support, adherence to Mediterranean diet and physical activity in adults: results from a community-based cross-sectional study.

There is a growing recognition that social support can potentially exert consistent or opposing effects in influencing health behaviours. The present paper presents a cross-sectional study, including 2,064 adults from Italy, Spain and Greece, who were participants in a multi-centre randomised controlled trial (C4H study), aiming to examine whether social support is correlated with adherence to a healthy Mediterranean diet and physical activity. Social support data were available for 1,572 participants. The majority of the sample reported emotional support availability (84·5 %), financial support availability (72·6 %) and having one or more close friends (78·2 %). Mediterranean diet adherence was significantly associated with emotional support (P = 0·009) and social network support (P = 0·021). No statistically significant associations were found between participant physical activity and the social support aspects studied. In conclusion, emotional and social network support may be associated with increased adherence to the Mediterranean diet. However, further research is needed to evaluate the role of social support in adherence to healthy Mediterranean diet.

Development of a conceptual framework for a group-based format of the Lifestyle-integrated Functional Exercise (gLiFE) programme and its initial feasibility testing.

BACKGROUND: The Lifestyle-integrated Functional Exercise (LiFE) programme is a fall prevention programme originally taught in a resource-intensive one-to-one format with limited feasibility for large-scale implementation. The aim of this paper is to present the conceptual framework and initial feasibility evaluation of a group-based LiFE (gLiFE) format developed for large-scale implementation. METHODS: The conceptual gLiFE framework (part I) is based on three pillars, LiFE Activities and Principles, Theory of Behaviour Change and Behaviour Change Techniques, and Instruction. The feasibility of gLiFE was tested (part II) within a multimodal approach including quantitative questionnaires measuring safety, acceptability (1 = best to 7 = insufficient), and adherence to the LiFE activities (range = 0-14) as well as a focus group interview. Exploratory self-reported measures on behaviour change including self-determined motivation (range = 1-5), intention, planning, action control, and habit strength (range = 1-6) were assessed pre and post intervention. Data analyses were performed using descriptive statistics and qualitative content analysis. RESULTS: The development process resulted in a manualised gLiFE concept containing standardised information on gLiFE's content and structure. Feasibility testing: Six older adults (median = 72.8 years, 5 female) completed the feasibility study and rated safety (median = 7.0, IQR = 0.3) and acceptability as high (median = 1, IQR = 1). Participants implemented 9.5 LiFE activities (IQR = 4.0) into their daily routines. No adverse events occurred during the study. In the focus group, the group format and LiFE activities were perceived as positive and important for maintaining strength and balance capacity. Self-determined motivation intention, planning, and habit strength were rated higher post intervention. CONCLUSION: The developed conceptual gLiFE framework represents the basis for a gLiFE format with potential for standardised large-scale implementation. Proof-of-concept could be demonstrated in a group of community-dwelling older adults at risk of falling. The public health potential of gLiFE in terms of (cost-)effectiveness is currently being evaluated in a large trial. TRIAL REGISTRATION: ClinicalTrials.gov NCT03412123.

Return to Everyday Activity in the Community and Home: a feasibility study for a lifestyle intervention to sit less, move more, and be strong.

BACKGROUND: Many interventions designed to meet physical activity guideline recommendations focus on a single component (e.g., walking), to the detriment of other elements of a healthy lifestyle, such as reducing prolonged sitting and doing balance and strength exercises (i.e., bundled multiple behaviors). Adopting these multiple health behaviors within daily life routines may facilitate uptake and support longer-term behavior change. We tested feasibility for a three-part lifestyle intervention to support older women to sit less, move more, and complete balance and strength exercises. METHODS: We used a convergent parallel mixed-methods, single-arm study design to test feasibility for a 6-week lifestyle intervention: Return to Everyday Activities in the Community and Home (REACH). We collected information at baseline, 3 and 6 weeks (final), and 6 months (follow-up) using questionnaires, semi-structured interviews, and performance-based measures. We describe three key elements: (1) implementation factors such as recruitment, retention, program delivery, and adherence; (2) participants' acceptability and experience with the program; and (3) health outcomes, including participants' global mobility, activity, and perceptions of their physical activity identity, and habit strength for (i) physical activity, (ii) breaking up sitting time, and (iii) balance and strength exercises. RESULTS: We were able to recruit enough participants in the allotted time to conduct one cycle of the REACH group-based program. There were 10 community-dwelling women, median (p25, p75) age 61 (57.5, 71) years, who completed the study. The program was feasible to deliver, with high attendance (mean 5/6 sessions) and positive overall ratings (8/10). Participants rated session content and length high, and educational materials as highly acceptable and understandable. Although participants were active walkers at baseline, few were breaking up prolonged sitting or participating in any balance and strength exercises. At final and follow-up assessments, participants reported developing habits for all three health behaviors, without diminishing physical activity. CONCLUSION: These results show acceptability of the program and its materials, and feasibility for bundling multiple health behaviors within the REACH program. It also provides confirmation to advance to testing feasibility of this three-part lifestyle intervention with older, less active, adults.

What makes a good action plan? Characteristics and enactment of fruit and vegetable plans.

BACKGROUND: One promising intervention strategy to increase fruit and vegetable (FV) consumption is action planning. However, conditions of successful plan enactment, i.e., the translation of plans into action, have rarely been studied. Therefore, the relationship between plan characteristics and plan enactment is being examined. METHODS: Secondary analyses of an existing data set were conducted, based on a larger behavioral intervention study with a baseline assessment as well as a 2-weeks and a 4-weeks follow-up. After baseline assessment, participants completed action plan calendars for the following seven days and subsequently reported on each plan's enactment. Two independent raters coded 1732 morning, noon/afternoon, and evening plans by n = 92 individuals regarding the level of specificity (unspecific vs. specific) and type of planned behavior (fruit vs. vegetable intake). To predict plan enactment, multilevel logistic regression analyses were conducted. FINDINGS: Overall specificity of plans was unrelated to plan enactment, but interacted with time of day in predicting plan enactment. Only in the morning, specific plans were more likely being enacted than unspecific plans. Overall, plan enactment decreased during the day and throughout the seven days of the plan calendar. Furthermore, fruit plans were more likely being enacted than vegetable plans. DISCUSSION: Specific morning plans were found most beneficial for the enactment of FV plans. Here, possible underlying mechanisms such as stable morning routines should be further investigated. Moreover, the nutritional choice appeared to make a difference for plan enactment: Increasing one's fruit consumption may be easier than integrating more vegetables into one's daily diet.
