Caractérisation de la plainte cognitive dans le vieillissement normal et le trouble cognitif léger

Le vieillissement étant un enjeu démographique majeur, il est capital de mieux comprendre les changements qui surviennent durant cette période de la vie. Il est connu que certaines fonctions cognitives sont modifiées avec l’avancée en âge. D’ailleurs, 25 à 50 % des personnes âgées de 65 ans et plus rapportent avoir observé un déclin de leur cognition et de leur mémoire. Les travaux de cette thèse portent sur la caractérisation de la plainte cognitive chez des personnes âgées saines et chez des aînés ayant un trouble cognitif léger (TCL) ainsi que sur son évolution au fil de la progression vers la maladie d’Alzheimer. La première étude (Chapitre II) avait pour objectif d’identifier les différents domaines de plainte mnésique chez des personnes d’âge moyen et des individus plus âgés. Elle visait également à vérifier si les domaines de plainte étaient associés aux performances aux tests neuropsychologiques. L’effet sur la plainte de certaines caractéristiques personnelles (âge, sexe, niveau de scolarité et symptômes dépressifs) a aussi été examiné. Le Questionnaire d’auto-évaluation de la mémoire (QAM; Van der Linden, Wijns, Von Frenkell, Coyette, & Seron, 1989) et plusieurs tests neuropsychologiques ont été complétés par 115 adultes sains âgés de 45 à 87 ans. Une analyse en composantes principales réalisée sur l'ensemble des questions du QAM a permis d’identifier sept grands domaines de plainte. Des analyses subséquentes ont révélé que les plaintes les plus fréquemment rapportées par les participants sont associées à des situations où des facteurs internes et externes interfèrent avec la performance mnésique. Les analyses ont aussi montré que les plaintes relatives à des oublis dont les conséquences menacent l’autonomie et la sécurité témoigneraient de problèmes cognitifs et fonctionnels plus sévères. Enfin, nos résultats ont indiqué que les différents domaines de plainte reflètent globalement les problèmes cognitifs objectifs. Aucune association n’a été trouvée entre la plainte et la plupart des caractéristiques démographiques. La seconde étude (Chapitre III) avait pour but de caractériser la plainte cognitive dans le TCL ainsi que son évolution dans la progression de la démence. L’étude cherchait aussi à déterminer si les changements dans certains domaines de plainte étaient reliés au déclin de ii fonctions cognitives spécifiques chez les individus avec TCL qui ont progressé vers la démence (progresseurs). Des personnes avec TCL et des individus âgés sains ont été évalués annuellement pendant trois ans. Le QAM et le Multifactorial Memory Questionnaire (MMQ; Fort, Holl, Kaddour, & Gana, 2004) ont été utilisés pour mesurer leurs plaintes. Les résultats ont révélé que les progresseurs rapportaient davantage de difficultés associées à la mémorisation de contenus complexes (ex. : textes ou conversations), d’événements récents et d’informations sur leurs proches que les personnes âgées saines et ce, jusqu’à trois ans avec le diagnostic de démence. L’analyse des effets de groupe a indiqué que l’intensité des plaintes des progresseurs semble être demeurée stable durant le suivi. Il est donc possible qu’une proportion des progresseurs présentent une méconnaissance de leurs difficultés cognitives. Cependant, des analyses corrélationnelles ont montré que l’augmentation des plaintes reliées à trois domaines était associée à l’accroissement de certaines atteintes cognitives durant les trois ans. Ainsi, certaines plaintes pourraient permettre de mieux comprendre les difficultés cognitives qui sont vécues par la personne avec TCL. Les implications théoriques et cliniques de ces résultats seront discutées dans le dernier chapitre de la thèse (Chapitre IV).

La relation entre l’importance accordée à la réussite scolaire par les parents et l’engagement scolaire des élèves d’origine haïtienne au primaire : l’effet modérateur de la relation maître-élève.

Le désengagement scolaire constitue un problème social important au Québec. Les difficultés qu’éprouvent certains élèves à suivre les instructions, à participer en classe et à s’investir dans leur travail scolaire peuvent, à plus long terme, influencer leur réussite scolaire et mener à l’échec ou au décrochage. Vu l’importance du rôle joué par les parents et les enseignants sur l’engagement, la présente étude a pour but d’étudier la contribution des parents et des enseignants à l’engagement comportemental des élèves d’origine haïtienne issus de l’immigration fréquentant des écoles primaires en milieux défavorisés à Montréal. Elle vise également à examiner comment la contribution de ces acteurs se combine pour favoriser l’engagement comportemental de ces élèves. Les données ont été recueillies auprès de 211 élèves de 3e à 5e année provenant d’écoles de milieux défavorisés et multiethniques sur l'île de Montréal, et de leurs enseignants. Les résultats de nos analyses de régressions montrent que la chaleur dans la relation maître-élève exerce un effet modérateur sur le lien entre l’importance accordée à la réussite scolaire et l’engagement comportemental. Ainsi, l’importance accordée à la réussite scolaire par les parents est plus importante pour l’engagement des élèves qui partagent des relations peu chaleureuses et amicales avec leur enseignant que pour leurs pairs qui ont de bonnes relations avec leur enseignant. Des pistes pour l’intervention et pour la recherche future sont présentées à la lumière de ces résultats.

L'Inventaire des risques et des besoins liés aux facteurs criminogènes (IRBC) : évaluation des propriétés métriques de l'instrument

L’Inventaire des risques et des besoins liés aux facteurs criminogènes (IRBC) est un instrument utilisé depuis le début des années 1990 pour évaluer les risques de récidive des jeunes contrevenants québécois. Il est le produit d’une collaboration du Québec avec l’Ontario, survenue dans le cadre de travaux de recherche effectués sur les instruments d’évaluation du risque de récidive des jeunes contrevenants. L’IRBC est donc le seul instrument précisément conçu pour évaluer les risques de récidive des jeunes contrevenants québécois et il n’a jamais fait l’objet d’une démarche visant à tester sa validité prédictive. Le but de ce projet de mémoire est de tester la validité prédictive de l’IRBC. Des analyses de courbes ROC et des analyses de survie ont été utilisées pour tester les propriétés métriques de l’instrument. Ces analyses suggèrent que, dans l’ensemble, l’IRBC arrive à prédire la récidive de façon acceptable. Quatre des huit grands domaines associés à la récidive, communément appelé BIG FOUR, seraient des prédicteurs modérés de la récidive lorsque testés avec les données issues de l’IRBC. Il s’agit des domaines Antécédents, Pairs, Personnalité-Comportements, et Attitudes-Tendances. Des aspects en lien avec la fidélité de l’instrument témoignent toutefois d’irrégularités dans le processus d’évaluation, ce qui interroge le niveau de rigueur maintenu au jour le jour par les professionnels. Des aspects en lien avec la fidélité de l’IRBC demeureraient à investiguer.

Sexual and relationship intimacy among women with provoked vestibulodynia and their partners : associations with sexual satisfaction, sexual function, and pain self-efficacy

Introduction Provoked vestibulodynia (PVD) is the most frequent subtype of vulvodynia. Women report negative consequences of PVD on their sexual and romantic relationships. Researchers have recently highlighted the importance of examining interpersonal factors such as intimacy, and of including both women and their partners in study designs. Aim The aim of this study was to investigate sexual and relationship intimacy as defined by the Interpersonal Process Model of Intimacy and their associations with sexual satisfaction, sexual function, pain self-efficacy, and pain intensity among women with PVD and their partners. Methods Ninety-one heterosexual women (M age = 27.38, SD = 6.04) diagnosed with PVD and their partners (M age = 29.37, SD = 7.79) completed measures of sexual and relationship intimacy, sexual satisfaction, sexual function, pain self-efficacy, and pain intensity. Main Outcome Measures Dependent measures were the (i) Global Measure of Sexual Satisfaction Scale; (ii) Female Sexual Function Index; (iii) Painful Intercourse Self-Efficacy Scale; and (iv) visual analog scale of pain intensity during intercourse. Results After controlling for women's age, women's greater sexual intimacy (β = 0.49, P < 0.001) was associated with women's greater sexual satisfaction and higher pain self-efficacy (β = 0.39, P = 0.001), beyond the effects of partners’ sexual intimacy. Also, women's greater sexual intimacy (β = 0.24, P = 0.05) and women's greater relationship intimacy (β = 0.54, P = 0.003) were associated with greater women's sexual function, beyond the effects of partners’ sexual and relationship intimacy. Conclusions Women's self-reported sexual and relationship intimacy in the couple relationship may promote higher sexual satisfaction, sexual function, and pain self-efficacy, as well as possibly foster greater sexual well-being among women with PVD. The authors discuss implications for the inclusion of emotional and interpersonal aspects of the couple's dynamic in clinical interventions and future research in PVD.

Attachment, sexual assertiveness and sexual outcomes in women with provoked vestibulodynia and their partners : a mediation model.

Provoked vestibulodynia (PVD) is a prevalent women’s sexual pain disorder, which is associated with sexual function difficulties. Attachment theory has been used to understand adult sexual outcomes, providing a useful framework for examining sexual adaptation in couples confronted with PVD. Research to date indicates that anxious and avoidant attachment dimensions correlate with worse sexual outcomes in community and clinical samples. The present study examined the association between attachment, pain, sexual function and sexual satisfaction in a sample of 101 couples in which the women presented with PVD. The Actor-Partner Interdependence Model was used in order to investigate both actor and partner effects. This study also examined the role of sexual assertiveness as a mediator of these associations via structural equation modeling. Women completed measures of pain intensity and both members of the couple completed measures of romantic attachment, sexual assertiveness, sexual function and satisfaction. Results indicated that attachment dimensions did not predict pain intensity. Both anxious and avoidant attachment were associated with lower sexual satisfaction. Only attachment avoidance predicted lower sexual function in women. Partner effects indicated that higher sexual assertiveness in men predicted better sexual function in women, while higher sexual assertiveness in women predicted higher sexual satisfaction in men. Finally, women’s sexual assertiveness was found to be a significant mediator of the relationship between their attachment dimensions, sexual function and satisfaction. Findings highlight the importance of examining how anxious and avoidant attachment may lead to difficulties in sexual assertiveness and to less satisfying sexual interactions in couples where women suffer from PVD.

Psychosexual aspects of vulvovaginal pain.

Vulvovaginal pain problems are major health concerns in women of childbearing age. Controlled studies have shown that vulvovaginal pain can adversely affect women and their partners’ general psychological well-being, relationship adjustment and overall quality of life. These women have significantly lower levels of sexual desire, arousal, and satisfaction, as well as a lower intercourse frequency than normal controls. They also report more anxiety and depression, in addition to more distress about their body image and genital self-image. Empirical studies indicate that specific psychological and relationship factors may increase vulvovaginal pain intensity and its psychosexual sequelae. Randomized clinical trials have shown that psychosexual interventions, namely cognitive-behavioral therapy (CBT), are efficacious in reducing vulvovaginal pain and improving associated psychosexual outcomes. Women reporting significant psychological, sexual and/or relationship distress should be referred for psychosexual treatment. A multimodal approach to care integrating psychosexual and medical management is thought to be optimal.

Feasibility and preliminary effectiveness of a novel cognitive-behavioral couple therapy for provoked vestibulodynia: a pilot study.

Introduction Provoked vestibulodynia (PVD), a recurrent, localized vulvovaginal pain problem, carries a significant psychosexual burden for afflicted women, who report impoverished sexual function and decreased frequency of sexual activity and pleasure. Interpersonal factors such as partner responses to pain, partner distress, and attachment style are associated with pain outcomes for women and with sexuality outcomes for both women and partners. Despite these findings, no treatment for PVD has systematically included the partner. Aims This study pilot‐tested the feasibility and potential efficacy of a novel cognitive–behavioral couple therapy (CBCT) for couples coping with PVD. Methods Couples (women and their partners) in which the woman was diagnosed with PVD (N = 9) took part in a 12‐session manualized CBCT intervention and completed outcome measures pre‐ and post‐treatment. Main Outcome Measures The primary outcome measure was women's pain intensity during intercourse as measured on a numerical rating scale. Secondary outcomes included sexual functioning and satisfaction for both partners. Exploratory outcomes included pain‐related cognitions; psychological outcomes; and treatment satisfaction, feasibility, and reliability. Results One couple separated before the end of therapy. Paired t‐test comparisons involving the remaining eight couples demonstrated significant improvements in women's pain and sexuality outcomes for both women and partners. Exploratory analyses indicated improvements in pain‐related cognitions, as well as anxiety and depression symptoms, for both members of the couple. Therapists' reported high treatment reliability and participating couples' high participation rates and reported treatment satisfaction indicate adequate feasibility. Conclusions Treatment outcomes, along with treatment satisfaction ratings, confirm the preliminary success of CBCT in reducing pain and psychosexual burden for women with PVD and their partners. Further large‐scale randomized controlled trials are necessary to examine the efficacy of CBCT compared with and in conjunction with first‐line biomedical interventions for PVD.

Why us? Perceived injustice is associated with more sexual and psychological distress in couples coping with genito-pelvic pain.

Introduction Provoked vestibulodynia (PVD) is the most frequent cause of genito-pelvic pain/penetration disorder (GPPPD) and is associated with negative psychological and sexual consequences for affected women and their partners. PVD is often misdiagnosed or ignored and many couples may experience a sense of injustice, due to the loss of their ability to have a normal sexual life. Perceiving injustice has been documented to have important consequences in individuals with chronic pain. However, no quantitative research has investigated the experience of injustice in this population. Aim The aim of this study was to investigate the associations between perceived injustice and pain, sexual satisfaction, sexual distress, and depression among women with PVD and their partners. Methods Women diagnosed with PVD (N = 50) and their partners completed questionnaires of perceived injustice, pain, sexual satisfaction, sexual distress, and depression. Main Outcome Measures (1) Global Measure of Sexual Satisfaction Scale; (2) Female Sexual Distress Scale; (3) Beck Depression Inventory-II; and (4) McGill-Melzack Pain Questionnaire. Results After controlling for partners' age, women's higher level of perceived injustice was associated with their own greater sexual distress, and the same pattern was found for partners. Women's higher level of perceived injustice was associated with their own greater depression, and the same pattern was found for partners. Women's higher perceived injustice was not associated with their own lower sexual satisfaction but partners' higher perceived injustice was associated with their own lower sexual satisfaction. Perceived injustice was not associated with women's pain intensity. Conclusion Results suggest that perceiving injustice may have negative consequences for the couple's sexual and psychological outcomes. However, the effects of perceived injustice appear to be intra-individual. Targeting perceived injustice could enhance the efficacy of psychological interventions for women with PVD and their partners.

Are primary and secondary provoked vestibulodynia two different entities? A comparison of pain, psychosocial and sexual characteristics.

Introduction Provoked vestibulodynia (PVD) is suspected to be the most frequent cause of vulvodynia in premenopausal women. Based on the onset of PVD relative to the start of sexual experience, PVD can be divided into primary (PVD1) and secondary PVD (PVD2). Studies comparing these PVD subgroups are inconclusive as to whether differences exist in sexual and psychosocial functioning. Aim The aim of this study was to compare the pain, sexual and psychosocial functioning of a large clinical and community-based sample of premenopausal women with PVD1 and PVD2. Methods A total of 269 women (n = 94 PVD1; n = 175 PVD2) completed measures on sociodemographics, pain, sexual, and psychosocial functioning. Main Outcome Measures Dependent variables were the 0–10 pain numerical rating scale, McGill–Melzack Pain Questionnaire, Female Sexual Function Index, Global Measure of Sexual Satisfaction, Beck Depression Inventory-II, Painful Intercourse Self-Efficacy Scale, Pain Catastrophizing Scale, State-Trait Anxiety Inventory Trait Subscale, Ambivalence over Emotional Expression Questionnaire, Hurlbert Index of Sexual Assertiveness, Experiences in Close Relationships Scale—Revised, and Dyadic Adjustment Scale-Revised. Results At first sexual relationship, women with PVD2 were significantly younger than women with PVD1 (P < 0.01). The average relationship duration was significantly longer in women with PVD2 compared with women with PVD1 (P < 0.01). Although women with PVD1 described a significantly longer duration of pain compared with women with PVD2 (P < 0.01), no significant subtype differences were found in pain intensity during intercourse. When controlling for the sociodemographics mentioned earlier, no significant differences were found in sexual, psychological, and relational functioning between the PVD subgroups. Nevertheless, on average, both groups were in the clinical range of sexual dysfunction and reported impaired psychological functioning. Conclusions The findings show that there are no significant differences in the sexual and psychosocial profiles of women with PVD1 and PVD2. Results suggest that similar psychosocial and sex therapy interventions should be offered to both subgroups of PVD.

To say or not to say : dyadic ambivalence over emotional expression and its associations with pain, sexuality, and distress in couples coping with provoked vestibulodynia.

Introduction Provoked vestibulodynia (PVD) is a highly prevalent and taxing female genital pain condition. Despite the intimate nature of this pain and the fact that affective factors such as anxiety have been shown to modulate its manifestations, no study has yet explored the emotional regulation of couples in which the woman suffers from PVD. Aim Ambivalence over emotional expression (AEE) is an emotional regulation variable that quantifies the extent to which a person is comfortable with the way she or he expresses emotions. We examined whether the dyadic AEE of couples in which the woman suffers from PVD was differentially associated with women's pain and couples' psychological, sexual, and relational functioning. Methods Couples (N = 254), in which the woman suffered from PVD, completed the AEE questionnaire. A couple typology of dyadic AEE was created. Main Outcome Measures Dependent measures for both members of the couple were the global measure of sexual satisfaction scale, the Beck depression inventory II, and the revised dyadic adjustment scale. The female sexual function index and the sexual history form were used to assess the sexual function of women and men, respectively. Women also completed the pain rating index of the McGill pain questionnaire. Results Couples, in which both partners were considered low on AEE, had the highest scores on sexual satisfaction (P = 0.02) and function (P < 0.01), the lowest depression scores (P < 0.01), and the best dyadic adjustment (P = 0.02). No difference in pain intensity was found between couples. Conclusions Findings suggest that, for couples in which the woman suffers from PVD, an emotional regulation that is low in ambivalence in both partners is associated with better psychological, sexual, and relational outcomes. Results indicate that emotional regulation may be important to consider in the assessment and treatment of couples coping with PVD.

Partner behavioral responses to pain mediate the relationship between partner pain cognitions and pain outcomes in women with provoked vestibulodynia.

Partner behavioral responses to pain can have a significant impact on patient pain and depression, but little is known about why partners respond in specific ways. Using a cognitive-behavioral model, the present study examined whether partner cognitions were associated with partner behavioral responses, which prior work has found to predict patient pain and depressive symptoms. Participants were 354 women with provoked vestibulodynia and their partners. Partner pain-related cognitions were assessed using the partner versions of the Pain Catastrophizing Scale and Extended Attributional Style Questionnaire, whereas their behavioral responses to pain were assessed with the Multidimensional Pain Inventory. Patient pain was measured using a numeric rating scale, and depressive symptoms were assessed using the Beck Depression Inventory–II. Path analysis was used to examine the proposed model. Partner catastrophizing and negative attributions were associated with negative partner responses, which were associated with higher patient pain. It was also found that partner pain catastrophizing was associated with solicitous partner responses, which in turn were associated with higher patient pain and depressive symptoms. The effect of partner cognitions on patient outcomes was partially mediated by partner behavioral responses. Findings highlight the importance of assessing partner cognitions, both in research and as a target for intervention. Perspective The present study presents a cognitive-behavioral model to partially explain how significant others' thoughts about pain have an effect on patient pain and depressive symptoms. Findings may inform cognitive-behavioral therapy for couples coping with PVD.

Women with provoked vestibulodynia experience clinically significant reductions in pain regardless of treatment : results from a 2-year follow up study.

Introduction Provoked vestibulodynia (PVD) is a prevalent genital pain syndrome that has been assumed to be chronic, with little spontaneous remission. Despite this assumption, there is a dearth of empirical evidence regarding the progression of PVD in a natural setting. Although many treatments are available, there is no single treatment that has demonstrated efficacy above others. Aims The aims of this secondary analysis of a prospective study were to (i) assess changes over a 2-year period in pain, depressive symptoms, and sexual outcomes in women with PVD; and (ii) examine changes based on treatment(s) type. Methods Participants completed questionnaire packages at Time 1 and a follow-up package 2 years later. Main Outcome Measures Visual analog scale of genital pain, Global Measure of Sexual Satisfaction, Female Sexual Function Index, Beck Depression Inventory, Dyadic Adjustment Scale, and sexual intercourse attempts over the past month. Results Two hundred thirty-nine women with PVD completed both time one and two questionnaires. For the sample as a whole, there was significant improvement over 2 years on pain ratings, sexual satisfaction, sexual function, and depressive symptoms. The most commonly received treatments were physical therapy, sex/psychotherapy, and medical treatment, although 41.0% did not undergo any treatment. Women receiving no treatment also improved significantly on pain ratings. No single treatment type predicted better outcome for any variable except depressive symptoms, in which women who underwent surgery were more likely to improve. Discussion These results suggest that PVD may significantly reduce in severity over time. Participants demonstrated clinically significant pain improvement, even when they did not receive treatment. Furthermore, the only single treatment type predicting better outcomes was surgery, and only for depressive symptoms, accounting for only 2.3% of the variance. These data do not demonstrate the superiority of any one treatment and underscore the need to have control groups in PVD treatment trials, otherwise improvements may simply be the result of natural progression.
