A Multisite Preregistered Paradigmatic Test of the Ego-Depletion Effect
We conducted a preregistered multilaboratory project (k = 36; N = 3,531) to assess the size and robustness of ego-depletion effects using a novel replication method, termed the paradigmatic replication approach. Each laboratory implemented one of two procedures that was intended to manipulate self-control and tested performance on a subsequent measure of self-control. Confirmatory tests found a nonsignificant result (d = 0.06). Confirmatory Bayesian meta-analyses using an informed-prior hypothesis (ÎŽ = 0.30, SD = 0.15) found that the data were 4 times more likely under the null than the alternative hypothesis. Hence, preregistered analyses did not find evidence for a depletion effect. Exploratory analyses on the full sample (i.e., ignoring exclusion criteria) found a statistically significant effect (d = 0.08); Bayesian analyses showed that the data were about equally likely under the null and informed-prior hypotheses. Exploratory moderator tests suggested that the depletion effect was larger for participants who reported more fatigue but was not moderated by trait self-control, willpower beliefs, or action orientation.</p
Etude des facteurs et des interventions basées sur le planning comportements de santé : applications à l'activité physique et à l'adhésion médicamenteuse
Individuals do not always enact their intentions into behaviours, which may lead to severe outcomes especially in health-related fields. Self-regulation strategies, like cuedependent plans interventions, have shown efficiency to help to counter the intentionbehaviour gap. Yet, no review has been realised recently to bring a qualitative and quantitative analyses of this effect.Firstly, we carried out a qualitative review to evaluate the effectiveness of cuedependent planning intervention to increase health-related behaviours. We included 329 studies with experimental and prospective designs that measured or evaluated the effect of cue-dependent plans (e.g. implementation intention, action planning, coping planning) on health-related behaviours, among general, clinical and student population. The qualitative analysis revealed for instance that implementation intentions were used in majority, even if the if-then format was not systematically adopted. However, we oticed confusion between the terminologies of the plans and the theories. A quantitative review will be realised to evaluate the effect size and the moderators that could magnify or diminish the effects of cuedependent planning interventions on health-related behaviours. Second, we presented two studies that tested the effectiveness of cue-dependent planning interventions on physical activity, which was the most represented health outcome in cue-dependent planning interventions, according to our review. Motivational (mental simulation) and volitional (implementation intention) interventions were combined to promote physical activity participation. The first study, adopting a cluster randomised controlled trial design among students, did not show any significant effect neither of the mental simulation plus implementation intention intervention, nor of the implementation intention intervention compared to the control condition. The second study adopted a more rigorous methodology with a full-factorial randomised controlled design, with a larger sample and objective measures of physical activity (attendance to gym centre). Nevertheless, the study revealed no statistically significant main or interactive effects of the mental simulation and implementation intention conditions on physical activity outcomes. Findings were not in line with previous research that showed effects of cue-dependent plans to promote physical activity. This adds to the necessity of identifying the moderators of these interventions in health behaviours.Thirdly, cue-dependent planning interventions are needed in illness behaviours. In chronic disease, non-adherence to medication is a public health problem that can lead to negative health outcomes. Even if the patients want to take their treatment, they may, for instance, forget it and fail to enact the behaviour. We tested the ability of an intervention adopting implementation intention and coping planning to promote medication adherence. In a randomized controlled trial, outpatients with cardiovascular diseases were randomly allocated to either an implementation intention and coping planning condition, or to a noplanning control condition. Findings revealed no significant effect of the intervention on medication adherence. However, post hoc moderator analyses showed that the beliefs moderated the effect of the intervention, which was effective in patients with lower necessity beliefs compared to those with higher necessity beliefs. The design used in the study did not enable to test the direct an interactive effect on medication adherence, so it would be necessary to replicate these findings with a full factorial design among patients with cardiovascular diseases.L'auteur n'a pas fourni de résumé en françai

Trouble du déficit de l'attention avec ou sans hyperactivité et tabagisme en milieu carcéral
International audienceIntroduction :Les personnes souffrant de Trouble du DĂ©ficit de lâAttention avec ou sans HyperactivitĂ© (TDAH) prĂ©sentent un risque accru de consommer du tabac (Lee et al., 2011) et ont gĂ©nĂ©ralement un profil tabagique plus sĂ©vĂšre qu'en population gĂ©nĂ©rale (VanAmsterdam et al., 2018). En population incarcĂ©rĂ©e, on observe une prĂ©valence du TDAH et du tabagisme plus Ă©levĂ©e quâen population gĂ©nĂ©rale(Jacomet et al., 2016 ; Young & Cocallis, 2019). Notre objectif est de vĂ©rifier si la consommation de tabac est plus sĂ©vĂšre chez les dĂ©tenus prĂ©sentant une symptomatologie du TDAH.MĂ©thode :Nous avons Ă©valuĂ© les variables suivantes :Consommation de tabac (auto-rapportĂ©e), dĂ©pendance Ă la nicotine (FTND), intensitĂ© du craving (FTCQ), motivation Ă l'arrĂȘt du tabac (Q-MAT), symptomatologie actuelle du TDAH (ASRS) et dans lâenfance (WURS).Nous avons effectuĂ© des comparaisons statistiques entre les individus probablement atteints d'un TDAH et ceux ne prĂ©sentant probablement pas de TDAH. Pour cela, les participants ont Ă©tĂ© classĂ©s dans le groupe "TDAH" seulement s'ils ont obtenu un score supĂ©rieur aux scores seuils dĂ©finis pour l'ASRS et la WURS.RĂ©sultats :Le groupe TDAH a prĂ©sentĂ© un Ăąge de dĂ©but de consommation rĂ©guliĂšre de tabac significativement plus faible que le groupe sans TDAH (U=275 ; p=0.019). De plus, les individus dĂ©pistĂ©s avec un TDAH ont affichĂ© un score total moyen significativement plus Ă©levĂ© Ă la FTND que le groupe sans TDAH (U=262 ; p=0.012). Cette tendance s'est Ă©galement observĂ©e pour le score total moyen obtenu Ă la FTCQ-12 (U=288 ; p=0.029). Cependant, aucune diffĂ©rence significative n'a Ă©tĂ© constatĂ©e au niveau du score total obtenu Ă la Q-MAT (U=402 ; p=0.400)et au nombre moyen de cigarettes fumĂ©es par jour (U=247 ;p=0.076).RĂ©sultats :Nos rĂ©sultats indiquent une plus grande sĂ©vĂ©ritĂ© de la consommation de tabac chez les dĂ©tenus prĂ©sentant des symptĂŽmes du TDAH. Ces observations soulignent l'importance du dĂ©pistage du TDAH et de l'adaptation des interventions pour la consommation de tabac en milieu carcĂ©ral lorsque des symptĂŽmes du TDAH sont prĂ©sents
Sévérité de la consommation de tabac et symptÎmes anxieux et dépressifs en milieu carcéral
International audienceIntroduction : Les troubles anxieux et dĂ©pressifs sont des comorbiditĂ©s frĂ©quentes du trouble de lâusage du tabac (Himle, Thyer &Fischer, 1988 ; Breslau et al., 1911). Ces troubles impactent lâinitiation, le maintien et lâarrĂȘt du tabagisme. De plus, leur sĂ©vĂ©ritĂ© est positivement corrĂ©lĂ©e avec le niveau de dĂ©pendance (Morrell & Cohen, 2006).En milieu carcĂ©ral, la prĂ©valence du tabagisme et des troubles anxieux et dĂ©pressifs est beaucoup plus Ă©levĂ©e quâen population gĂ©nĂ©rale (Fovet et al., 2020 ; Jacomet el al., 2016). Lâobjectif de cette Ă©tude est de vĂ©rifier si la sĂ©vĂ©ritĂ© des symptĂŽmes anxieux et dĂ©pressifs est associĂ©e Ă lâintensitĂ© de la consommation de tabac chez une population incarcĂ©rĂ©e.MĂ©thode : 91 hommes consommateurs de tabac ont Ă©tĂ© Ă©valuĂ©s Ă leur arrivĂ©e Ă la maison dâarrĂȘt Paris-La SantĂ©. Nombre de cigarettes consommĂ©es par jour (auto-rapportĂ©es). Nous avons Ă©valuĂ© les variables suivantes : - DĂ©pendance Ă la nicotine : Fagerström Test for Nicotine Dependence (FTND),- IntensitĂ© du craving : French Tobacco Craving Questionnaire(FTCQ-12),- Motivation Ă l'arrĂȘt du tabac : Questionnaire de Motivation Ă l'ArrĂȘt du Tabac (Q-MAT),- Symptomatologie anxieuse et dĂ©pressive actuelle : Hospital and Anxiety and Depression Scale, HADS).RĂ©sultats : Les participants ont obtenu un score moyen Ă lâHAD-anxiĂ©tĂ© de 7,75 (Ï =5,01) et Ă lâHAD-dĂ©pression de 4,67 (Ï = 3,89). 28 individus ont dĂ©passĂ© le score seuil de lâHAD (score â„ 11 : symptomatologie certaine) pour la dimension anxiĂ©tĂ© (30,77%), et 6 lâont Ă©galement dĂ©passĂ© pour la dimension dĂ©pression (6,59%). Nous avons observĂ© une corrĂ©lation positive significative entre le score total obtenu Ă lâHAD-anxiĂ©tĂ© et le score total obtenu Ă la FTND (r = 0,29 ; p < 0,001) ainsi quâavec le score total Ă la FTCQ (r = 0,35 ; p < 0,001). Nous avons Ă©galement constatĂ© une corrĂ©lation positive significative entre le score total obtenu Ă lâHAD-dĂ©pression et le score total obtenu Ă la FTCQ (r = 0,30 ; p = 0,004). Cependant, aucune corrĂ©lation significative nâa Ă©tĂ© trouvĂ©e entre lâHAD-dĂ©pression et le score obtenu Ă la FTND (r = 0,06 ; p = 0,61). Concernant le nombre de cigarette consommĂ©es par jour, aucune corrĂ©lation nâa Ă©tĂ© retrouvĂ©e avec le score obtenu Ă la dimension dĂ©pression (r = 0,12 ; p = 0,33) et Ă la dimension anxiĂ©tĂ© (r = 0,20 ; p = 0.94).Discussion : Les rĂ©sultats ont permis de mettre en Ă©vidence lâintensitĂ© Ă©levĂ©e dessymptĂŽmes anxieux et dĂ©pressifs Ă lâarrivĂ©e en incarcĂ©ration. Comme nous lâattendions, des corrĂ©lations ont Ă©tĂ© constatĂ©es entre lâintensitĂ© des symptĂŽmes anxieux et la sĂ©vĂ©ritĂ© de la dĂ©pendance au tabac ainsi quâentre lâintensitĂ© des symptĂŽmes anxieux et dĂ©pressifs et lâintensitĂ© du craving. L'importance de dĂ©velopper et d'Ă©valuer des interventions spĂ©cifiquement adaptĂ©es Ă la population incarcĂ©rĂ©e pour favoriser le sevrage tabagique apparait donc comme un enjeu important. Cette nĂ©cessitĂ© est dâautant plus urgente en raison de la vulnĂ©rabilitĂ© particuliĂšre de cette population face aux problĂ©matiques psychiatriques et addictologiques

Theory-Based Interventions Combining Mental Simulation and Planning Techniques to Improve Physical Activity: Null Results from Two Randomized Controlled Trials.
Interventions to assist individuals in initiating and maintaining regular participation in physical activity are not always effective. Psychological and behavioral theories advocate the importance of both motivation and volition in interventions to change health behavior. Interventions adopting self-regulation strategies that foster motivational and volitional components may, therefore, have utility in promoting regular physical activity participation. We tested the efficacy of an intervention adopting motivational (mental simulation) and volitional (implementation intentions) components to promote a regular physical activity in two studies. Study 1 adopted a cluster randomized design in which participants (n = 92) were allocated to one of three conditions: mental simulation plus implementation intention, implementation intention only, or control. Study 2 adopted a 2 (mental simulation vs. no mental simulation) Ă 2 (implementation intention vs. no implementation intention) randomized controlled design in which fitness center attendees (n = 184) were randomly allocated one of four conditions: mental simulation only, implementation intention only, combined, or control. Physical activity behavior was measured by self-report (Study 1) or fitness center attendance (Study 2) at 4- (Studies 1 and 2) and 19- (Study 2 only) week follow-up periods. Findings revealed no statistically significant main or interactive effects of the mental simulation and implementation intention conditions on physical activity outcomes in either study. Findings are in contrast to previous research which has found pervasive effects for both intervention strategies. Findings are discussed in light of study limitations including the relatively small sample sizes, particularly for Study 1, deviations in the operationalization of the intervention components from previous research and the lack of a prompt for a goal intention. Future research should focus on ensuring uniformity in the format of the intervention components, test the effects of each component alone and in combination using standardized measures across multiple samples, and systematically explore effects of candidate moderators

Implementation intention and planning interventions in Health Psychology: Recommendations from the Synergy Expert Group for research and practice.
The current article details a position statement and recommendations for future research and practice on planning and implementation intentions in health contexts endorsed by the Synergy Expert Group. The group comprised world-leading researchers in health and social psychology and behavioural medicine who convened to discuss priority issues in planning interventions in health contexts and develop a set of recommendations for future research and practice. The expert group adopted a nominal groups approach and voting system to elicit and structure priority issues in planning interventions and implementation intentions research. Forty-two priority issues identified in initial discussions were further condensed to 18 key issues, including definitions of planning and implementation intentions and 17 priority research areas. Each issue was subjected to voting for consensus among group members and formed the basis of the position statement and recommendations. Specifically, the expert group endorsed statements and recommendations in the following areas: generic definition of planning and specific definition of implementation intentions, recommendations for better testing of mechanisms, guidance on testing the effects of moderators of planning interventions, recommendations on the social aspects of planning interventions, identification of the preconditions that moderate effectiveness of planning interventions and recommendations for research on how people use plans
Vigdis og Bergljot. Og Vera? â Ein studie av sjĂžlvframstilling i Arv og miljĂž og Fri vilje.
Dette er ein studie av sjÞlvframstilling i rÞyndomslitteraturen. OppgÄva dreiar seg om korleis forfattarar gjev seg til kjenne i sin eigen tekst og kva konsekvenser dette kan fÞra med seg. Meir bestemt tek denne avhandlinga utgangspunkt i sjÞlvframstillinga til Vigdis Hjorth i romanen Arv og miljÞ.
Problemstillinga er: Korleis kan feedback skapa og endra bilete av Vigdis Hjorth i Arv og miljĂž?
For Ä svara pÄ denne problemstillinga har eg valt Ä analysera Arv og miljÞ ut ifrÄ ymse lesarars perspektiv i ein gjeven tidsperiode. BÄde det innanfor og utanfor romanen er avgjerande for kva bilete ein kan danna seg av forfattaren.
Analysen er delt inn i tre delar: I perioden fÞr og under utgjevinga er kjennskap til forfattaren og feedback i form av bokkritikkar og liknande eit viktig grunnlag for korleis ein sidan vil tolka Arv og miljÞ. Feedbacken under utgjevingsperioden gav to moglege forstÄingar av kva Arv og miljÞ er eit resultat av. Den eine forstÄinga gÄr i retning av Ä tolka romanen som Vigdis Hjorths litterÊre prosjekt, den andre som Vigdis Hjorths litterÊre metode. Desse forstÄingane er avgjerande for kva bilete ein dannar seg av forfattaren.
I neste del, under lesnaden av Arv og miljĂž, dreier fokuset mot Ă„ undersĂžkja om bileta som feedbacken har gjeve er valide etter ei gjennomlesing. Lesnaden stadfesta biletet av Vigdis Hjorth som driv med eit litterĂŠrt prosjekt, i stĂžrre grad enn at ho driv med ein litterĂŠr metode.
Eitt Är seinare kom feedbacken Fri vilje ut. Dette er ein roman som er skriven av den eine systera til Vigdis Hjorth. Mens lesnaden av Arv og miljÞ stadfesta biletet av Vigdis Hjorth som ei som driv med eit litterÊrt prosjekt, stadfestar Fri vilje den litterÊre metoden i Arv og miljÞ. Dette betyr at begge bileta som feedbacken skapa har fÄtt kvar si litterÊre framstilling, noko som igjen fÞrer til at dei er vanskelege Ä bÄde avkrefta og sannkjenna. Dette er fordi bileta undergrev kvarandre: Berre eitt av dei kan stemma, men nÄr begge ogsÄ finst i kvar sine litterÊre framstillingar vil det alltid herska tvil om kva som er tilfellet
