Families with Children with Autism, Developmental Delay, and Typical Development: The Relationships of Parenting Self-Efficacy, Parenting Strategies, and Child Problem Behaviour

Parents of children with autism spectrum disorders (ASD) and developmental delays (DD) may experience more child problem behaviours, report lower parenting selfefficacy (PSE), and be more reactive than proactive in their parenting strategies than those who have children with typical development (TD). Differences in PSE and parenting strategies may also influence the extent to which child problem behaviours are experienced by parents who have children with ASD and DD, compared to those who have children with TD. Using a convenience sample of parents of children with ASD (n = 48), DD (n = 51), and TD (n = 72), this study examined group differences on three key variables: PSE, parenting strategies, and child problem behaviour. Results indicated that those in the DD group scored lower on PSE in preventing child problem behaviour than the ASD group. The TD group used fewer reactive strategies than the DD group, and fewer proactive strategies than both the ASD and DD groups. For the overall sample, higher reactive strategies use was found to predict higher ratings of child problem behaviour, while a greater proportion of proactive to reactive strategies use predicted lower ratings of child problem behaviour. PSE was found to moderate DD diagnosis and child problem behaviour. Implications for a behavioural (i.e., parenting strategies) or cognitive (i.e., PSE) approach to parenting are discussed.

Parent and Peer Factors Relating to Adolescent Antisocial Behaviour: Investigating the Moderating Role of Temperament

The purpose of this study was to examine whether certain temperament characteristics (fearfulness, surgency, frustration, and effortful control) moderate the association between authoritative parenting dimensions (psychological autonomy granting, acceptance-involvement, and monitoring knowledge) or friends' antisocial behaviour, and self-reported antisocial behaviour among adolescents. Questionnaires on adolescent temperament and authoritative parenting were completed by 484 mothers and their adolescent children (54.8% female). In addition, the adolescents responded to measures regarding friends' antisocial behavior and their own antisocial behaviour. Adolescent participants ranged between 13 and 17 years of age (M = 14.96 years, SD = 1.39) and lived in a region of southern Ontario. As predicted, the results indicated that effortful control moderated the association between parental monitoring knowledge and adolescent antisocial behaviour. Also, as predicted, effortful control moderated the relation between friends' antisocial behaviour and adolescents' self-reports of antisocial behaviour although the relation was sex-specific to girls. Unexpected results included a significant monitoring knowledge by frustration by sex interaction, and a significant friends' antisocial behaviour by age interaction. In general, the findings were consistent with the expectation that the relation of parenting and peer factors to antisocial behaviour would depend on adolescents' temperamental predispositions. However, effortful control, which contributes to individual differences in self-regulation abilities, served this moderating role to a greater extent than the measures of temperamental reactivity, including fearfulness, surgency and frustration-proneness. Implications of these results are discussed with reference to parenting or classroom-based interventions that may be especially helpful for adolescents with poor self-regulation abilities.

Investigating Changes in Parent Knowledge about Obsessive Compulsive Behaviour Following Group Function-Based Cognitive Behavioural Therapy for Children with High Functioning Autism

This study investigated improvements in parent knowledge of effective intervention strategies following participation in a group function-based CBT treatment (GFbCBT) package for children with comorbid OCD and ASD. Nineteen parents of children ages 7-12 years with High Functioning Autism (HFA) participated in the 9-week treatment program. Key components of treatment included psychoeducation and mapping, cognitive-behavioural skills training, function-based interventions and exposure and response prevention (ERP). Treatment sessions also included direct parent education, which followed a behavioural skills training model (Miltenberger, 2008). Parent knowledge (N = 19) was measured pre and post treatment using a vignette about a child demonstrating obsessive-compulsive behaviour. Results of a one-tailed pairwise t-test indicated statistically significant changes (p=.036) in overall parent knowledge following participation in treatment. Statistically significant changes were also found in parents’ ability to generate ERP and function-based intervention strategies. These results provide preliminary evidence that parents benefit from active involvement in the GFbCBT treatment package.

Examination of students' ability to observe domains of client behaviour in therapeutic recreation

When observing client behaviours, a therapeutic recreation specialist must have a base understanding of typical client behaviours to provide an informed analysis (burlingame & Blaschko, 2010). Providing students with the necessary tools for client observation is significant to the success of this process. The purpose of this study was to assess the relationships amongst the TR student demographic characteristics on acquiring the observation competency necessary to conduct a TR assessment. One hundred seventy-two TR college and university students, enrolled in post-secondary undergraduate TR programs across Ontario, observed a client assessment via video, and recorded their observations using the Tracking Behavioural Assessment (TBA) (Passmore, 2002). Independent samples t-tests and analysis of variance were calculated for the different student characteristics on the domains of the TBA. Significant findings indicated that university students scored more accurately than college students, and advanced students more accurately than novice students, on the emotional and socialization domains.

Can a Manipulated Mind Alter Matter? : The Effects of Verbal Feedback on Self-Efficacy, Exercise Intention, and Exercise Behaviour among Low-Active College-Aged Women

Self-efficacy (SE), a person’s confidence in the ability to perform a task, is an important predictor of the adoption and maintenance of physical activity. The present study examined the effects of SE manipulated through verbal persuasion on exercise intentions and behaviour during a 4-week follow-up period and investigated the role of social physique anxiety (SPA) as a moderator. Female college infrequent exercisers (n = 66) were randomly assigned into one of three groups (high-efficacy [HE], low-efficacy [LE], or control) and asked to complete several questionnaires at baseline. The HE and LE groups were provided with positive and negative exercise adherence feedback, respectively. The HE group reported higher SE from pre- to post-feedback. Both the HE and LE groups reported increases in exercise behaviour at the 4-week follow-up. Pre- to post-feedback changes in SE, exercise intention, and exercise behaviour did not depend on level of SPA reported.

Psychopathy and Antisocial Behaviour: The Moderating Effects of Maternal Neglect and Warmth

Psychopathy researchers have long debated the role of antisocial behaviour and criminality as part of the construct of psychopathy. The current study examined the relationship between the interpersonal and affective traits (Factor 1) of psychopathy and antisocial behaviour (a facet of Factor 2), examining possible predictors of antisocial behaviour. It was hypothesized that early environment would moderate the relationship between Factor 1 traits and antisocial behaviour. Hierarchical multiple regression analyses were used in order to test for possible moderators. Sex differences were found, where men scored higher in Antisocial Behaviour. Childhood Abuse did not moderate the relationship between Factor 1 traits and Antisocial Behaviour, but predicted higher Antisocial Behaviour scores independently. Maternal Neglect was especially influential as a risk factor, significantly interacting with Factor 1 traits to predict higher Antisocial Behaviour scores. Maternal Warmth was also important, interacting with Factor 1 in a protective fashion, predicting lower Antisocial Behaviour Scores.

Explaining voice behaviour: The roles of personal resources, social interdependence, and supervisor leadership style

This study contributes to current research on voice behaviour by investigating several under-explored drivers that motivate employees’ expression of constructive ideas about work-related issues. It draws from the concept of psychological climate to examine how voice behaviour is influenced by employees’ (1) personal resources (tenacity and passion for work), (2) perceptions of social interdependence (task and outcome interdependence), and (3) supervisor leadership style (transformational and transactional). Using a multi-source research design, surveys were administered to 226 employees and to 24 supervisors at a Canadian-based not-for-profit organization. The hypotheses are tested with hierarchical regression analysis. The results indicate that employees are more likely to engage in voice behaviour to the extent that they exhibit higher levels of passion for work. Further, their voice behaviour is lower to the extent that their supervisor adopts a transformational leadership style characterized by high performance expectations or a transactional leadership style based on contingent rewards and contingent punishment behaviours. The study reveals that there are no significant effects of tenacity, social interdependence, and behaviour-focused transformational leadership on voice. The findings have significant implications for organizations that seek to encourage employee behaviours that help improve current work practices or undo harmful situations.

Anticipated Guilt and Ethical Consumption: The Moderating Role of Consumers’ Socially Responsible Consumption Behaviour

Recent research in the marketing literature has indicated that, while consumers’ interests in ethical products are growing, demand for such products still remains weak. Previous research has indicated that anticipated guilt can have a positive effect on ethical consumption. Thus, the objective of the current study is to investigate the moderating role of consumers’ socially responsible consumption behaviour (SRCB) on the relationship between anticipated guilt and ethical consumption. Specifically, the current study hypothesizes that, when viewing a guilt ad, high (vs. low) SRCB individuals will generate higher, ethical purchase intentions, willingness to pay an ethical premium, and attitudes toward an ethical brand. The findings from the two experimental studies indicate that, when viewing a guilt ad for an ethical product, high SRCB individuals are willing to pay a higher ethical premium and generate more favourable brand attitudes than low SRCB individuals. However, when viewing a non-guilt ad, high SRCB individuals did not differ from low SRCB individuals in their willingness to pay an ethical premium or brand attitudes. Further, consumers’ socially conscious self-identity was explored as a mediator of these effects. By understanding the moderating role that SRCB plays in the relationship between anticipated guilt and ethical consumption, this paper intends to assist marketers in understanding for which consumers a guilt appeal is an appropriate strategy in marketing ethical products.

Evaluating Knowledge of a Function-based Cognitive-Behavioural Treatment for Obsessive Compulsive Behaviour in Autism Spectrum Disorder

Children with Autism Spectrum Disorder (ASD) have restricted and repetitive behaviours (RRBs) which may be similar to obsessions and compulsions in Obsessive Compulsive Disorder (OCD). These behaviours can be intrusive and interfere in the lives of the child and their family. Preliminary studies have shown success in using adapted Cognitive Behavioural Therapy (CBT) to treat these behaviors in children with high functioning ASD. Using a hypothetical vignette, this thesis attempted to examine procedural knowledge that the children and their parents gained while participating in a CBT treatment that was evaluated in a Randomized Controlled Trial. For both parents and children, there was a significant increase in number of strategies generated from pre to post-treatment. Further, children in the experimental group generated significantly more strategies than the treatment as usual (TAU) group post-intervention. There was no significant correlation between number of strategies generated and the child’s treatment success, age, or IQ.

The Ligand and Membrane-binding Behaviour of the Phosphatidylinositol Transfer Proteins (PITPa & PITPb)

Human Class I phosphatidylinositol transfer proteins (PITPs) exists in two forms: PITPα and PITPβ. PITPs are believed to be lipid transfer proteins based on their capacity to transfer either phosphatidylinositol (PI) or phosphatidylcholine (PC) between membrane compartments in vitro. In Drosophila, the PITP domain is found to be part of a multi-domain protein named retinal degeneration B (RdgBα). The PITP domain of RdgBα shares 40 % sequence identity with PITPα and has been shown to possess PI and PC binding and transfer activity. The detailed molecular mechanism of ligand transfer by the human PITPs and the Drosophila PITP domain remains to be fully established. Here, we investigated the membrane interactions of these proteins using dual polarization interferometry (DPI). DPI is a technique that measures protein binding affinity to a flat immobilized lipid bilayer. In addition, we also measured how quickly these proteins transfer their ligands to lipid vesicles using a fluorescence resonance energy transfer (FRET)-based assay. DPI investigations suggest that PITPβ had a two-fold higher affinity for membranes compared to PITPα. This was reflected by a four-fold faster ligand transfer rate for PITPβ in comparison to PITPα as determined by the FRET assay. Interestingly, DPI analysis also demonstrated that PI-bound human PITPs have lower membrane affinity compared to PC-bound PITPs. In addition, the FRET studies demonstrated the significance of membrane curvature in the ligand transfer rate of PITPs. The ligand transfer rate was higher when the accepting vesicles were highly curved. Furthermore, when the accepting vesicles contained phosphatidic acid (PA) which have smaller head groups, the transfer rate increased. In contrast, when the accepting vesicles contained phosphoinositides which have larger head groups, the transfer rate was diminished. However, PI, the favorite ligand of PITPs, or the presence of anionic lipids did not appear to influence the ligand transfer rate of PITPs. Both DPI and FRET examinations revealed that the PITP domain of RdgBα was able to bind to membranes. However, the RdgBα PITP domain appears to be a poor binder and transporter of PC.

Mâle dans leur poids : une étude sur les variables explicatives de la préoccupation des hommes québécois avec surpoids à l'égard du poids

L’objectif de cette recherche qualitative était de porter un regard sur la problématique du poids chez l’homme à partir des déterminants de la santé masculine définis par Courtenay (2003). En donnant la parole à 17 hommes québécois en surpoids lors d’entrevues individuelles, différentes variables associées à leur préoccupation à l’égard du poids, sont examinées. Selon ces hommes, il existe un comportement alimentaire typiquement masculin autant dans le choix des aliments que dans la façon de manger. La présence féminine joue pour eux un rôle prépondérant dans ce domaine. La vision masculine de la santé suit souvent la fonctionnalité de leur corps tandis que leur description du surpoids semble davantage partir du « vécu » et être moins stricte que la définition purement médicale. Néanmoins, beaucoup d’hommes sentent la pression de l’image du corps idéal masculin et sont souvent insatisfaits de leur corps selon la masculinité valorisée et selon la stigmatisation subie. La préoccupation des hommes à l’égard de leur santé est très présente parmi les hommes de 30-45 ans et perdre du poids dans ce contexte devient alors légitime mais les raisons évoquées varient : la santé, l’apparence, le bien-être. L’expression des douleurs émotionnelles autour du poids est difficile pour les hommes et trop souvent la masculinité traditionnelle constitue une barrière de taille à la consultation pour ces problèmes. Pour le futur, il sera donc important pour les professionnels de la santé d’intégrer les différentes caractéristiques de cette masculinité traditionnelle dans leur approche et leur communication avec les hommes en surpoids.
