Show moreAbstractObjectivePrevious research has shown that experiencing an acute cardiac event, such as a myocardial infarction (MI), can lead to lifestyle changes. This study aimed to explore the potential of a MI as a ‘teachable moment’ (TM) for positive lifestyle changes and to identify psychosocial sensemaking processes that facilitate or hinder the presence of a TM.MethodWe conducted semi-structured interviews with 14 patients who suffered their first MI and were hospitalized in a larger Dutch city. Participants were interviewed twice, respectively one and five months after their hospitalization. They were encouraged to explain how they experienced their MI and how this had affected their lifestyle. We used an Interpretative Phenomenological Analysis approach to the data collection and analysis.FindingsThe participants varied in their willingness to adopt a healthy lifestyle due to their MI. Most participants experienced their event as a TM for changing specific health behaviors, for example facilitated by reflecting on self-concept or social roles and by constructing and comprehending a personal narrative of their MI. Some participants struggled to follow through on their intentions to change their behavior, for example because of a negative attitude towards a healthy behavior or because they perceived it as incongruent to their identity. Only three participants maintained most former health behaviors, for example because they failed to acknowledge their MI as severe or because of earlier life events that elicited more blunted cognitive responses.ConclusionCardiac patients may experience a TM, which is the consequence of interrelated processes of psychosocial sensemaking. As this does not occur at a singular time point, we suggest using the term ‘teachable window’ rather than ‘moment’. Given these findings, there is a window of opportunity to provide continuous psychosocial and lifestyle support during and after hospitalization for acute cardiac events. Show less

Show moreYoung individuals frequently share and encounter alcohol-related content (i.e., alcohol posts) on social networking sites. The prevalence of these posts is problematic because both the sharing of and exposure to these posts can increase young individuals’ alcohol (mis)use. Consequently, it is essential to develop effective intervention strategies that hinder young individuals from sharing these posts. This study aimed to develop such intervention strategies by following four steps: (1) assessing young individuals’ problem awareness of alcohol posts, (2) unraveling individuals’ own intervention ideas to tackle the problem of alcohol posts, (3) examining their evaluations of theory/empirical-based intervention ideas, and (4) exploring individual differences in both problem awareness and intervention evaluations. To reach these aims, a mixed-method study (i.e., focus-group interviews and surveys) among Dutch high-school and college students (Ntotal = 292, Agerange = 16–28 years) was conducted. According to the results, most youth did not consider alcohol posts to be a problem and were, therefore, in favor of using automated warning messages to raise awareness. However, these messages might not work for every individual, as group differences in problem awareness and intervention evaluations exist. Overall, this study puts forward potential intervention ideas to reduce alcohol posts in digital spheres and can therefore serve as a steppingstone to test the actual effects of the ideas. Show less

My future-self has (not) quit smoking: an experimental study into the effect of a future-self intervention on smoking-related self-identity constructs

Show moreObjectives: Envisioning one's (non)smoking future may make (un)desired future identities more accessible, salient, and personally relevant and facilitate smoking cessation. The current study assessed whether a future-self intervention can weaken smoker self-identity and expected identity loss when quitting smoking, and strengthen quitter-and nonsmoker self-identity, while accounting for personal factors-socioeconomic position, nicotine dependence, consideration of future consequences, and clarity of the envisioned future-self. Additionally, it examined the association between smoking-related identity and quitting intention and behavior. Methods: This longitudinal online experimental study randomized 233 adult smokers to an intervention condition (where they completed mental imagery, visual, and verbal tasks about a future (non)smoking self), or to a passive control condition. Smoker-, quitter-, nonsmoker self-identity and identity loss were measured post-intervention and after one-and three-months. Quit intention and attempts were measured at baseline and after one month. Results: There was a consistent increase in non-smoker self-identity, and decrease in smoker self-identity and identity loss over a period of six months for all participants, but no significant difference in smoking-related identity between the intervention and control group. While personal factors did not moderate the effect of the intervention, we found that smoking-related identity constructs do vary with nicotine dependence, consideration of future consequences, and clarity of the envisioned future-self. Quitting behavior is primarily associated with non-smoker self-identity. Conclusions: Although the future-self intervention did not significantly influence smoking-related identity or behavior, identity-in particular, non-smoker self-identity-is important to consider in smoking cessation in-terventions. More research is needed to find effective operationalizations for identity-based interventions in the context of smoking. Show less

Show moreIdentity, or 'who I am', is important for smoking behaviour. Identity constructs (parts of a person's identity) are typically examined as separate entities, but emerging evidence suggests that the multifaceted nature of identity is relevant in the context of smoking. This cross-sectional study examined how smoking-related self- and group-identity constructs cluster within adult daily smokers (N = 231), whether classes of smokers can be distinguished based on clusters of identity constructs, and which factors explain class membership. Data were collected online in The Netherlands and Belgium, 2017-2018. Latent class and regression tree analyses showed that participants in Class 1 of 'Identified smokers' (estimated population share 54%) reported stronger smoker self- and group-identities, stronger expected identity loss when quitting smoking, and weaker quitter self-identities and non-smoker self- and group-identities (vs. Class 2 of 'Conflicted smokers'). Class membership was explained by the interaction between mental smoking dependence (dominant explanatory variable), consideration of future consequences, age of smoking onset, self-efficacy, and future self thought clarity. Models had good fit. The identity of more dependent smokers is more strongly oriented toward smoking. Smoking is also more strongly embedded in the identity of smokers who started smoking young, are less inclined to think about the future, and have lower self-efficacy. Show less

Show moreIntroduction Smoking and insufficient physical activity (PA), independently but especially in conjunction, often lead to disease and (premature) death. For this reason, there is need for effective smoking cessation and PA-increasing interventions. Identity-related interventions which aim to influence how people view themselves offer promising prospects, but an overview of the existing evidence is needed first. This is the protocol for a scoping review aiming to aggregate the evidence on identity processes and identity-related interventions in the smoking and physical activity domains. Methods The scoping review will be guided by an adaption by Levac et al of the 2005 Arksey and O'Malley methodological framework, the 2020 Preferred Reporting Items for Systematic Reviews and Meta-Analyses: Extension for Scoping Review (PRISMA-ScR) and the 2017 Joanna Briggs Institute guidelines. It will include scientific publications discussing identity (processes) and/or identity-related interventions in the context of smoking (cessation) and/or physical (in)activity, in individuals aged 12 and over. A systematic search will be carried out in multiple databases (eg, PubMed, Web of Science). Records will be independently screened against prepiloted inclusion/exclusion criteria by two reviewers, using the Active Learning for Systematic Reviews machine learning artificial intelligence and Rayyan QCRI, a screening assistant. A prepiloted charting table will be used to extract data from included full-text articles. Findings will be reported according to the PRISMA-ScR guidelines and include study quality assessment. Ethics and dissemination Ethical approval is not required for scoping reviews. Findings will aid the development of future identity-related interventions targeting smoking and physical inactivity.

Show moreAlcohol posts on social media frequently receive likes that are often perceived by emerging adults as peer approval of alcohol consumption and have been linked to their drinking intentions in previous research. This research, however, has generally not considered the fact that liking is a reciprocal behavior that differs from day to day. By conducting an app-integrated daily diary study and employing a network analytic approach, the current study contributes to this line of research by providing a better understanding of the dynamics of likes for alcohol posts and how these likes, in turn, affect emerging adults' actual alcohol use. In total, 265 college students (M-age = 20.49, SDage = 1.89, 74% female) participated in the daily diary study. They answered daily questionnaires about their alcohol use, and we monitored their online activities (posting and liking) via an app. We used exponential random graph models to predict the probability of receiving a like on a post and generalized linear mixed effect models to estimate the likelihood of participants drinking alcohol. First, the results showed that participants received, on average, more likes for alcohol posts than for non-alcohol posts (30 vs. 15 likes). Second, likes were given more often if they were reciprocal. Last, liking alcohol posts significantly predicted participants' alcohol consumption on the same day. The fact that liking alcohol posts relates to daily drinking behavior is disconcerting because one click or 'like' might reinforce a young person's drinking behavior on that day; hence, future research and interventions should focus more thoroughly on this worrying form of online approval.

Show moreBackground: Adolescents and young adults frequently post alcohol-related content (ie, alcoholposts) on social media. This is problematic because both social norms theory and social learning theory suggest that viewing alcoholposts of peers could increase drinking behavior. It is therefore paramount to understand the effects of exposure to alcoholposts on viewers.Objective: This study aimed to investigate the causal effects of exposure to alcoholposts on alcohol consumption by using a rigorous design.Methods: We conducted a 6-week longitudinal study during which alcoholposts were measured by a newly developed app that copied Facebook posts shared by participants (n=281) to a new social media environment. In addition, daily questionnaires assessed alcohol use. Effects of natural alcoholposts (ie, posted by the participants) were assessed in phase 1, and effects of experimental posts (ie, posted by fake participants) were explored in phase 2.Results: Results showed that natural alcoholposts increased the occurrence and quantity of drinking the following day. That is, exposure to a single additional alcoholpost increased the log odds of drinking the next day by 0.27 (b=.27, credible interval [CI] .18 to .35). Furthermore, the number of natural alcoholposts had a positive (predictive) effect on the number of glasses drunk the next day (b=.21, CI .14 to .29). In phase 2 when experimental posts were also present, these effects decreased. Experimental posts themselves had hardly any effects.Conclusions: This study illustrates clear and direct effects of exposure to alcoholposts on next-day alcohol consumption and suggests that alcoholposts represent an important societal problem that interventions need to address.

Show moreObjective: When lifestyle changes are needed, life events or crises such as COVID-19 may function as "teachable moments". This study aimed to explore whether the pandemic can provoke a teachable moment regarding lifestyle change in cardiovascular disease patients. Method: In this cross-sectional survey study, 830 cardiovascular disease patients reported their intentions to change lifestyle, instigated by the corona crisis, together with risk perception, affective impact, and changed self-concept, based on a "teachable moments" framework. Results: Between 8 and 28% of the sample reported increased intentions to optimize lifestyle behaviors, particularly related to general lifestyle (28%), physical activity (25%), and diet (21%). Multivariate regression analyses revealed that changed self-concept was associated with higher intentions to improve general lifestyle (B = 0.26; CI = 0.19-0.33), physical activity (B = 0.23; CI = 0.16-0.30), and smoking (B = 0.29; CI = 0.01-0.57). In addition, changed self-concept and affective impact were both significantly associated with higher intentions to improve diet (resp. B = 0.29; CI = 0.21-0.36 and B = 0.12; CI = 0.04-0.21) and to limit alcohol consumption (resp. B = 0.22; CI = 0.13-0.30 and B = 0.11; CI = 0.01-0.20). We did not find evidence for an important role of risk perception on behavior change intentions. Conclusion: The COVID-19 crisis evoked a potential teachable moment for lifestyle change in cardiovascular disease patients, driven by a change in a patient's self-concept and to a lesser extent by an affective impact of the COVID-19 crisis. These results suggest an important window of opportunity for healthcare professionals to utilize the pandemic to promote a healthy lifestyle to their patients. Show less
