Relapse prevention after pain management is a neglected area and Internet-based interventions have the potential to partly fill this gap. A challenge in designing effective relapse prevention program is how to motivate patients to persist throughout the full length of treatment. Following a regular pain management program, 29 participants underwent a 20 week long Internet–based relapse prevention program based on acceptance-oriented CBT. Qualitative analyses showed changes in attitudes towards their pain and body during the course of treatment. Degree of personal commitment in treatment goals seemed to affect gains relating to new perspective on self and future. Therapeutic strategies of defusion and mindfulness seemed to ease perspective changes and persistence to comply. Values interventions are hypothesized to be a plausible therapeutic strategy to engage participants in continuous behavior change. Further studies on non-compliers and drop-outs could enhance understanding of interventions necessary to maintaining motivation. When and how to give therapist support during Internet-based treatment for chronic pain is another area in need of further studies.

Motivations, Attitudes and Modern Languages. A study of students’ motivational processes and attitudes while learning foreign languages. This doctoral thesis investigates students’ motivational processes and attitudes while studying and learning foreign languages (FLs). Students were asked about their choice of FL, and what had motivated them during their many years of studies. The study analyzes open-ended questionnaires and interviews with 43 students enrolled in the last year of foreign language studies in two schools, limiting its focus to the three most commonly studied FLs – French, German and Spanish. The theoretical framework of the thesis draws on sociocognitive theory (Bandura 1997; Linnenbrink & Pintrich 2002). Several informants refer to motivation in terms that could be related to intrinsic motivation. They have chosen to continue studying their particular target language due to an emotional state which could be related to enjoyment, pleasure and curiosity (Deci & Ryan 1985). Another salient feature is the frequent reference to mastery goals. Many of the informants express a motivation directed towards mastery and growth, or a main goal to be fluent or communicatively competent in their target language. Several informants also underline the motivational importance of experiencing competence, success and development. They become motivated by experiencing self-efficacy (Bandura 1997). This self-efficacy is rooted in experience of success, but also in being encouraged by significant others or role models, i.e. family members and friends. Despite a frequent awareness of the weakening general interest for FL, most students have a supportive network. Likewise, family and friends play a crucial role for many informants while choosing their target language initially. This key factor interacts with other important factors, such as the experiences of visiting countries or settings where the target language is used. In this context, target language attitudes tend to be important when choosing language and pursuing studies.

Différents courants de recherches se sont intéressés à identifier les compliments à éviter afin de ne pas nuire au développement de l’estime de soi et des processus motivationnels optimaux chez les enfants (p.ex. Kamins et Dweck, 1999 ; Kast et Konnor, 1988). Pourtant, aucune étude n’avait tenté d’identifier les compliments potentiellement optimaux pour favoriser ces développements. À travers 3 études, cette thèse exploratoire visait ainsi à comparer différents types de compliments recensés comme positifs dans la documentation à l’aide d’un échantillon de dyades mères-enfants (N = 65 ; Âge moyen des enfants = 10,20 ans). La première étude de la thèse a examiné les relations entre les différents types de compliments, d’une part, et l’estime de soi et les processus motivationnels des enfants, d’autre part, tout en contrôlant pour les variables démographiques de sexe et d’âge des enfants. Étant donné que les différents types de compliments étaient hautement susceptibles de coexister, mais qu’ils n’avaient jamais été comparés au sein d’une même étude, leurs relations avec les variables dépendantes ont été examinées en considérant également leurs interrelations à l’aide de régressions multiples. La deuxième étude de cette thèse visait à mettre en lumière les liens entre la perception des enfants des pratiques parentales typiques de leur mère et les compliments recensés comme positifs dans la documentation grâce à des questionnaires complétés par les enfants et leur mère. La troisième étude, de nature expérimentale, a examiné les impacts situationnels des compliments comparatifs, orientés vers le résultat et descriptifs sur la compétence perçue (ou l’estime de soi situationnelle) et les processus motivationnels des enfants en s’intéressant aux impacts potentiels de trois modérateurs susceptibles d’accentuer ou de diminuer l’impact de la manipulation expérimentale, soit le sexe, l’âge et l’estime de soi globale des enfants. Les principaux résultats révèlent qu’il est possible de dresser un portrait des compliments rapportés comme positifs dans la documentation en distinguant quatre types : les compliments comparatifs, orientés vers le résultat, orientés vers l’effort et descriptifs. Deux de ces compliments, les compliments orientés vers le résultat et les compliments orientés vers l’effort, semblent être les plus utilisés. La thèse révèle également que seul le compliment descriptif semble lié positivement à l’estime de soi des enfants (globale et situationnelle), en particulier chez les filles et chez les enfants ayant une estime de soi plus faible que la moyenne. À travers ces trois objectifs, cette thèse contribue à l’avancement des connaissances sur les compliments, à la théorie de l’autodétermination (TAD) et permet d’identifier des pistes d’interventions qui permettront aux parents d’intervenir et de communiquer de façon optimale auprès de leurs enfants. / Different lines of research have focused on compliments that parents should avoid in order not to jeopardize the development of children’s self-esteem and optimal motivational processes (e.g. Kamins and Dweck, 1999; Kast and Konnor, 1988). However, no study had yet attempted to identify potentially optimal compliments to favor these developments. Through three studies, this exploratory thesis thus aimed at comparing different compliments conceptualized as positive in the literature using a sample of mother-child dyads (N = 65, mean age of the children = 10.20 years). The first study examined the relations between different types of compliments, on one hand, and children's self-esteem and motivational processes on the other, while controlling for demographic variables of children’s sex and age. Given that the different types of compliments were likely to coexist but were never compared in a single study, their relations with the dependent variables were examined while also controlling for their interrelations using multiple regressions. The second study aimed at highlighting the links between children's perception of their mother typical parenting practices and the different types of compliments conceptualized as positive in the literature. To investigate these relations, we relied on questionnaires filled out by two different respondents (children and their mothers). The third study relied on an experimental design to investigate the situational impacts of comparative, result-oriented and descriptive compliments on children's perceived competence (or their situational self-esteem) and motivational processes, with a focus on the potential impacts of three moderators likely to accentuate, or reduce, the effect of the experimental manipulation (i.e. sex, age and children's global self-esteem). The main results show that it is possible to provide a comprehensive portrait of the compliments conceptualized as positive in the literature by distinguishing four types: comparative, result-oriented, process-oriented and descriptive compliments. Two of these compliments, namely result-oriented compliments and process-oriented compliments, seem to be the most used. The thesis also reveals that only descriptive compliments seem positively related to children's self-esteem (global and situational), especially for girls and children reporting lower than average self-esteem. Through the pursuit of these three objectives, this thesis contributes to the advancement of knowledge on compliments, to self-determination theory (SDT) and helps identify intervention avenues that will allow parents to intervene and communicate optimally with their children.
