Intentions : «This study aims to shed light on the mechanisms by which motivational factors for dietary self-care are facilitated in adolescents with diabetes. Based on SDT [self-determination theory], longitudinal relationships between environmental and motivational factors for dietary self-care are examined.» (p. 153)
Questions/Hypothèses : «It was hypothesized that autonomy support from parents and health care providers at T1 [time one] would relate positively to perceived autonomous self-regulation and self-efficacy at T2 [time two], and that this perception at T1 would relate positively to dietary self-care at T2.» (p. 155)
Échantillon/Matériau : «Participants were recruited from two major pediatric diabetes centers in Québec (Canada). In all, 316 patients were invited to participate, of whom 289 (156 boys) agreed.» (p. 154)
Instruments : - Autonomous Self-Regulation Scale - Perception of Parents Scale (POPS) - Health Care Climate Questionnaire - Diet subscale of the Summary of Diabetes Self-Care Activities scale
Type de traitement des données : Analyse statistique
«The results support most of the hypothesized relationships, except for the proposal that parental autonomy fosters subsequent motivational factors. However, consistent with past research, autonomy support from health care providers positively predicts autonomous self-regulation and self-efficacy over time. The results also show that these motivational factors were associated with dietary self-care over two years. Autonomous self-regulation and dietary self-care were reciprocally related: improvement in one contributes to improvement in the other. Moreover, self-efficacy predicted subsequent perceived autonomy support from parents, and equivalently for boys and girls. The results revealed no association between parental support and adolescents’ motivational factors, although these constructs were significantly related. […] This study suggests that the more adolescents feel that health care providers understand their dietary self-care challenges, accept them as they are, and provide them with choices, the more they will be autonomously motivated toward dietary self-care, and the greater their confidence in achieving this over time.» (p. 155-156)

Intentions : « The purpose of the present study was to test the model presented (model of career indecision based on self-determination theory (Deci et Ryan, 1985)). [...] In addition, we looked for potential gender differences at the mean and process levels. » (p. 168)
Échantillon/Matériau : 834 étudiants de niveau collégial, canadiens-français (236 hommes, 581 femmes et 17 dont le genre n’a pas été identifié). L’âge moyen des participants est de 17,7 ans et 97 % sont au Québec. Le revenu moyen de leur famille varie entre 30 000$ et 40 000$.
Instruments : - The Career Decision scale (Osipow, 1987) - The Career Decision Making Self-Efficacy Scale-short form (Betz, Klein, & Taylor, 1996) - Carrer Decision-Making Autonomous Scale (Guay, 2001) - Parental Control and Autonomy Support Scale (Pelletier, 1992) - Peer Control and Autonomy Support Scale (Pelletier, 1992) - Neuroticism (du Psychiatric Symptoms Index subscales par Ilfeld (1976)), traduit et validé en français par Villeneuve, Valois, Frenette et Sévigny (1996) pour l’Enquête Santé-Québec. Type de traitement des données : Analyse statistique.
« The purpose of this study was to propose and test a model of career indecision based on self-determination theory (E. L. Deci & R. M. Ryan, 1985). This model posits that peer and parental styles predicted career indecision through perceived self-efficacy and autonomy. Participants were 834 college students (236 men, 581 women, 17 without gender identification). Results from structural equation modeling provided support for the proposed model and showed that the model was invariant across gender. Discussion centers on the theoretical and practical implications of the results. » (p. 165)
