Опубликована: Сен. 24, 2024

Abstract Objectives Behaviour change theories have extensively been used in health behaviour interventions and their programme theories. However, they are rarely evaluated randomized field studies. The Let's Move It intervention targeted various psychosocial constructs to increase adolescents' physical activity. A theory‐based process evaluation aiming illuminate the trial findings as well test theory is conducted. Specifically, we investigate whether influenced theorized determinants of immediately post‐intervention after 1 year, these were associated with changes Design cluster‐randomized controlled ( n = 1166). Methods We measured self‐report, activity (PA) accelerometry self‐report. effects repeated measures ANOVA regression models. Results No detected most but arm reported higher enactment techniques during lower descriptive norms for PA throughout. Autonomous motivation was post‐intervention. Conclusions lack may be due many factors, example insensitive measures, ceiling effects. reporting null advances understanding processes. introduce methodologic possibilities future efforts.

Effectiveness of the Let’s Move It multilevel school-based intervention on physical activity and sedentary behaviour: A cluster randomised trial

Опубликована: Ноя. 22, 2023

Background: Physical activity (PA) declines in late adolescence, particularly among those with low education. Few trials have tested interventions to decrease sedentary behaviour (SB). No school-based shown lasting effects on PA or (SB) older adolescents. Purpose: To examine whether the multi-component Let’s Move It intervention has an effect behavioural and clinical outcomes adolescents after two 14 months.Methods: A cluster randomised trial six school units vocational education Finland (N=1112) (mean age 18.5 years, range 15-46). The targeted in-class opportunities, students’ motivation self-regulation. Valid (≥4 days, ≥10 hours/d) accelerometer data was obtained from 741 students at baseline, 521 (70.3%) 2 months, 406 (54.8%) months.Results: evidence of a significant three co-primary found. arm reduced their total daily SB time by 32 minutes (95% CI -43.2 -20.8) weekdays, compared control arm’s reduction 8.6 -19.5 2.3) engaged more accelerometer-measured light during time. differences were found secondary outcomes. Fidelity delivery relatively good.Conclusions: Low-dose might not provide sufficient intensity affect leisure-time activity. Despite positive outcome school-time PA, comprehensive intensive environmental changes may be needed meaningfully improve adolescents’

Improving motivating behaviours of physical activity promotion and sports professionals: acceptability of and behavioural changes during the MotiStyleSport intervention

Опубликована: Янв. 30, 2024

Background: Motivating interaction by physical activity professionals result in stronger, more high-quality motivation and sustained health behaviours. However, often encounter difficulties adopting sustaining motivating behaviours existing training studies have failed to show long-lasting effects. This may be due inadequate examination of intervention acceptability (e.g. perceived effectiveness, burden). Secondly, trainings so far underused behaviour science, although systematic use such understanding change techniques (BCTs) as habit-theory based strategies might efficiently improve styles. Research questions: We examined whether the novel MotiStyleSport is acceptable among care professionals, education teachers sport coaches (pre-registered hypothesis), their BCT enactment. also explored uptake behaviours, pre-post changes (de)motivating styles.Methods: In a one-arm feasibility study, participants (n=145) attended six two-hour online sessions multiprofessional groups filled surveys at baseline, mid-intervention post-intervention.Results: The (overall training, sessions, homework, workbook, peer support, multiprofessionality, delivery) was highly all professional groups. enactment varied, ranging from least enacted social support (8.3%) most obtaining information about antecedents (96.3%). Approximately 90% reported practising popular (open questions, reflective listening displaying appreciation acceptance). Statistically significant improvements desired directions were detected styles within groups.Discussion: study provided evidence for intervention. Incorporating range BCTs, has potential trainings.

We present a novel framework for understanding the diverse spectrum of mental breakthrough events, ranging from problem-solving insights to profound personal transformations. propose that these while varied in expression and impact, share common underlying mechanisms representational change. also hypothesise differences phenomenological intensity can be conceptualised along continuum. Our model introduces three core components – tension, altered salience, enhanced flexibility as essential prerequisites significant cognitive restructuring. These interact within an iterative cycle, influencing both emergence nature insight experiences. Utilising examples different fields, we explore how conflict between existing models trigger this wherein attention allocation relaxation constraints intertwine facilitate insights. “aha-moment” breadth its impact are contingent on central is one's conceptual landscape extent which challenged. Thus, accounts subtle, momentary transformative realisations reshape beliefs self-perception.

Exploring boundary conditions of sustained physical activity: insights for the debate on physical activity maintenance

Опубликована: Май 3, 2024

Objective: Sustained physical activity is crucial for health and often referred to as 'physical maintenance.' However, this concept lacks consensus, possibly due limited study of the 'boundary conditions' under which phenomenon occurs. This gap limits both theoretical development interventional applications. examined boundary conditions two operational definitions maintenance (activity threshold timescale) how their formulation impacts detection sustained phenomena. Methods: We analyzed 352 time series (length=182 days) moderate-to-vigorous (MVPA) collected daily with Fitbit from participants in a weight loss intervention. Two thresholds were defined based on participants’ baseline intentions levels: a) 150 minutes MVPA/week below at (subsample BL-Inactive; n=101), b) current level those exceeding BL-Active; n=251). Regression trees used examine changes trajectories using different timescales (7, 14, 28, 56 days). Results: At finer-grained (7 days), exhibited repeated fluctuations, patterns 27% BL-Inactive 5% BL-Active participants. coarser-grained (56 more stable, percentages increasing 71% 26%. Conclusions: Varying reveal ways conceptualizing phenomena, leading plausibly distinct conclusions about behavioral maintenance. These results highlight importance carefully studying critical robust theory practice development.

How do behavioral public policy experts see the role of complex systems perspectives? An expert interview study

Translational Behavioral Medicine, Год журнала: 2024, Номер 14(7), С. 417 - 425

Опубликована: Май 22, 2024

Amidst the global momentum of behavioral insights (BI), there has been a shift from mostly nudge-based BI applications to systemic approaches. This is particularly pressing in public health, where interacting issues regularly produce unanticipated consequences. Regardless, little known about adopting complex systems approaches policy. study aims capture current practices international experts on definition, application, drivers, and hindering factors Semi-structured individual expert interviews (n = 12) with extensive experience educating, cooperating with, and/or advising servants were analyzed inductive content analysis. While working definition aligned published definitions, varied their descriptions its significance for policy, including socioecological aspects, systematic use across policy stages, recognizing intertwined behavior, lack ready-made solutions. They emphasized importance approaches, identifying drivers (e.g. need broader focus) hindrances pressure quick results). Embracing provides holistic perspective, extending beyond simple nudges, sometimes presumed as universally applicable. complexity perspectives would align policymakers' worldview, require more work tailor local situations evaluate.

From a false sense of safety to resilience under uncertainty

Frontiers in Psychology, Год журнала: 2024, Номер 15

Опубликована: Май 27, 2024

Understanding and acting upon risk is notably challenging, navigating complexity with understandings developed for stable environments may inadvertently build a false sense of safety. Neglecting the potential non-linear change or "black swan" events - highly impactful but uncommon occurrences lead to naive optimisation under assumed stability, exposing systems extreme risks. For instance, loss aversion seen as cognitive bias in environments, it can be an evolutionarily advantageous heuristic when complete destruction possible. This paper advocates better accounting decision-making by leveraging insights from complex psychological sciences, which help identify blindspots conventional develop mitigation plans that are interpreted contextually. In particular, we propose framework using attractor landscapes visualize interpret system dynamics. this context, attractors states toward naturally evolve, while tipping points critical thresholds between profound, unexpected changes impacting system's resilience well-being. We present four generic landscape types provide novel lens viewing risks opportunities, serve contexts. The main practical contribution clarifying emphasize particular strategies optimisation, mitigation, exploration, stabilization within framework. Context-appropriate decision making should enhance mitigate

Navigating Firestorms: The Imperative of Conflict-Intelligent Leadership in a Turbulent World

Negotiation Journal, Год журнала: 2024, Номер 40(1-2), С. 5 - 40

Опубликована: Янв. 1, 2024

Abstract This article offers a novel framework for conceptualizing conflict-intelligent leadership, which builds on evidence-based practices constructive conflict resolution but extends and enhances them with new insights strategies gleaned from complexity science. It argues that the development of intelligence (CIQ) requires broadening one’s orientation to across four levels: focus awareness self (implicit beliefs, emotional reactions, ability self-regulate), social dynamics (interpersonal, intergroup, moral dynamics), as well situational (conflicts in fundamentally different contexts), ultimately broader systemic forces may determine be determined by more entrenched conflicts. The defines CIQ, outlines competencies skills conducive increasing it at each level, set “toolkits,” links relevant resources such online assessments, “just-in-time” apps, popular articles. aim this is offer leaders road map; common vision, language, skill navigating our often dizzying, contentious world.
