Developing habit-based health behaviour change interventions: twenty-one questions to guide future research.

OBJECTIVE: Habitual behaviours are triggered automatically, with little conscious forethought. Theory suggests that making healthy behaviours habitual, and breaking the habits that underpin many ingrained unhealthy behaviours, promotes long-term behaviour change. This has prompted interest in incorporating habit formation and disruption strategies into behaviour change interventions. Yet, notable research gaps limit understanding of how to harness habit to change real-world behaviours. METHODS: Discussions among health psychology researchers and practitioners, at the 2019 European Health Psychology Society 'Synergy Expert Meeting', generated pertinent questions to guide further research into habit and health behaviour. RESULTS: In line with the four topics discussed at the meeting, 21 questions were identified, concerning: how habit manifests in health behaviour (3 questions); how to form healthy habits (5 questions); how to break unhealthy habits (4 questions); and how to develop and evaluate habit-based behaviour change interventions (9 questions). CONCLUSIONS: While our questions transcend research contexts, accumulating knowledge across studies of specific health behaviours, settings, and populations will build a broader understanding of habit change principles and how they may be embedded into interventions. We encourage researchers and practitioners to prioritise these questions, to further theory and evidence around how to create long-lasting health behaviour change.

Correlations Among High School Students' Beliefs about Conspiracy, Authoritarianism, and Scientific Literacy.

Studies consistently show the social impact of spreading epistemologically unfounded beliefs (or 'conspiracy beliefs'), including negative effects on public health. The present study identified correlations among epistemologically unfounded beliefs, authoritarianism, and scientific literacy in a representative sample of 303 Slovak secondary school students, using the Epistemologically Unfounded Beliefs Scale, Right-Wing Authoritarianism Scale, and Scientific Reasoning Scale. Statistical analysis confirmed significant correlations among the three variables. The findings suggest that increasing scientific literacy could simultaneously reduce authoritarianism and epistemologically unfounded beliefs in secondary school students.

Is wearing high heels a female mating strategy? Revisiting the original study using qualitative methods.

The 2020 study entitled 'Wearing high heels as female mating strategy' by Pavol Prokop and Jana Svancárová claimed that when females imagined an interaction with an attractive male, their preference for high heels steeply increased, compared with an imagined interaction with an unattractive male. The authors concluded that wearing high heels seem to be a form of sexual signaling by females in intersexual interactions. The present paper revisits this study through a psychological standpoint, rather than a biological one. In addition to proposing hypothetical dating scenarios, as in the original study, we also asked participants about how they went about getting ready to go on a date, the significance of dating to them, and their thinking behind choosing particular outfits for a date. We conducted ten focus groups (N = 50), recruiting from a similar sample of participants to those in the original study. For our study we followed principles of Thematic Analysis to identify the key themes in the narratives related to dating and beautification. We also used the photo elicitation methodology to observe what footwear our participants own. Our data interpretation from these two sources suggests that young women tend to see dates as social events not necessarily leading to sex; that they do not regard high heel shoes as a means of beautification; and that they take account of practical considerations when getting dressed up for a date. Moreover, young women tend to use beautification with caution. We conclude that the relationship between the tendency to use beautification and attractiveness of a potential partner is far from straightforward; and relying on binary responses to hypothetical scenarios does not provide convincing evidence.

Superlatives, clickbaits, appeals to authority, poor grammar, or boldface: Is editorial style related to the credibility of online health messages?

Adolescents, as active online searchers, have easy access to health information. Much health information they encounter online is of poor quality and even contains potentially harmful health information. The ability to identify the quality of health messages disseminated via online technologies is needed in terms of health attitudes and behaviors. This study aims to understand how different ways of editing health-related messages affect their credibility among adolescents and what impact this may have on the content or format of health information. The sample consisted of 300 secondary school students (M age = 17.26; SD age = 1.04; 66.3% female). To examine the effects of manipulating editorial elements, we used seven short messages about the health-promoting effects of different fruits and vegetables. Participants were then asked to rate the message's trustworthiness with a single question. We calculated second-order variable sensitivity as the derivative of the trustworthiness of a fake message from the trustworthiness of a true neutral message. We also controlled for participants' scientific reasoning, cognitive reflection, and media literacy. Adolescents were able to distinguish overtly fake health messages from true health messages. True messages with and without editorial elements were perceived as equally trustworthy, except for news with clickbait headlines, which were less trustworthy than other true messages. The results were also the same when scientific reasoning, analytical reasoning, and media literacy were considered. Adolescents should be well trained to recognize online health messages with editorial elements characteristic of low-quality content. They should also be trained on how to evaluate these messages.

Pain as Social Glue: A Preregistered Direct Replication of Experiment 2 of Bastian et al. (2014).

Bastian et al. (2014) found that sharing a painful experience promoted later intergroup cooperation. In Bastian et al.'s second experiment, 62 participants were assigned to groups of two to six people each. They performed either two painful or two painless tasks and then played an economic game. The present study consisted of two replications of the experiment: The first was a nonpreregistered pilot study (N = 153 students from the Czech Republic), and the second was a preregistered direct replication (N = 158 students from Slovakia). Important deviations from the original procedure were that (a) gender homogeneity of the small groups was balanced across the conditions and (b) the number of participants in each small group was fixed at three. No relevant effect of shared pain on cooperation emerged. The findings indicate that the true effect of shared pain on cooperation obtained in the original study may have been an overestimate or that the effect is not generally valid across various contexts.

Use of hallucinogens in Slovakia: Does it differ from global trends?

BACKGROUND: People have been using hallucinogens for thousands of years and interest in these substances has grown in recent years. The aim of this study was to determine the basic socio-demographic data, preferences, experiences, and attitudes associated with hallucinogen use in Slovakia. METHODS: A cross-sectional research design was used whereby an online survey included participants who had had at least one experience with hallucinogens (N = 422, age M = 27.78; SD = 7.84; SE = 0.38; 35.1% females). Due to the illegal, intimate, and minority nature of the phenomena studied, data was collected using the snowball sampling method via an online social network in groups that declared a drug focus. RESULTS: Users of hallucinogens were mostly employed (61,8%) and in some form of partnership (57,6%); they usually have a high school diploma (46,68%) or a university degree (45,41%). They most often use psilocybin mushrooms, while the age of initial use (M = 19,61; SD = 5,39) as well as lifetime frequency use (M = 18,26; SD =  24,21; Median =  10) are similar to global trends. Free use without rituals was preferred to ceremonial use. In general, our sample of hallucinogen users considered the integration of psychedelic experiences to be simple rather than challenging. Concurrently, they tended to see hallucinogens as useful to humans, but realised that they are not without risk and can be somewhat dangerous. Males used hallucinogens for the first time at a younger age (p < .05, r = -.12), used more hallucinogens during their lifetime (p <.001, r = -.23), and demanded decriminalisation and legalisation more (p <.01, r = -.13) than females. CONCLUSION: Slovak users of hallucinogens in our sample showed similar usage trends as users abroad. Even though both males and females perceive and evaluate hallucinogens very similarly, females are significantly more careful in using these substances.

Qualitative inquiry into reasons why vaccination messages fail.

A growing tendency to refuse child vaccination is commonly regarded as a reason for concern. Attempts to promote vaccination by authorities often prove to be unsuccessful or even counter-productive. The aim of this study was to explore how parents perceived four messages used to promote vaccination. In eight focus groups ( N = 73), we presented participants with messages and asked them to assess them. Using thematic analysis, we identified themes that our participants considered the most important. Messages that promote vaccination should be unambiguous, more balanced, not focus on repeating the negative effects of vaccine-preventable diseases and provide links to the evidence.
