This study sought to examine two gaps in the field of bullying research – (1) the lack of clear cut theoretical underpinnings and frameworks for examining the process of bullying and (2) oversight of the parent context in studies on bullying. This two-study dissertation examined the role of parents in understanding bullying, victimization and bystander behaviors using Belsky’s parenting process model (1984) as a potential guiding framework. Study 1 relied on secondary analysis with three waves of longitudinal data from the NICHD Study of Early Child Care and Youth Development to test the indirect effect of maternal depressive symptoms on bullying and victimization through mother-child relationship quality. Findings indicated that there was a small direct effect of maternal depressive symptoms at grade 3 on peer victimization at grade 5, but not bullying. Mother–child relationship quality at grade 5 negatively predicted bullying behaviors at grade 6, but not peer victimization. There were also small effects of bullying behaviors at grade 5 on increased maternal depressive symptoms and decreased mother-child relationship quality at grade 6. There were no significant indirect effects. Study 2, a cross-sectional study of N = 143 fourth and fifth graders and their parents, hypothesized indirect effects of parent’s general and specific self-efficacy related to bullying, peer victimization and bystander behaviors through parental monitoring and supervision. Parents’ self-efficacy beliefs related to knowledge of their children being victimized, and what to do about the victimization reports was directly and negatively associated with a reduction in bullying and victimization behaviors. Efficacy to know what to do was also negatively associated with negative bystander behaviors but positively associated with victimization in school. There were no significant indirect effects. Findings from both studies suggest that the parent context may play a limited role in processes of bullying during upper-elementary school. Secondly, parent functioning (i.e., maternal depressive symptoms, parental self-efficacy related to bullying) may have direct effects on bullying, victimization and bystander behaviors rather than indirectly through parenting as emphasized by Belsky’s model. Other findings, limitations and suggestions for future research and interventions are discussed.

Due to increased rates of childhood obesity since 2010, researchers have examined family environmental factors and family influences on children's consumption of healthy foods. While previous research has examined how factors such as food presentation and the food intake of other family members can predict a child's body mass index, there has been little research examining whether parent factors predict the amount of healthy foods children eat. This quantitative survey study examined whether certain parent factors, specifically parents' attitudes about food, parents' feeding styles, and parents' attachment styles, predicted the amount of fruits and vegetables children ate. Understanding the extent to which these factors predict children's actual consumption of healthy foods, rather than predicting their body mass index, will further inform the healthcare field about parents' role in their children's physical development. Family systems theory served as the theoretical foundation. Seventy-four parents of children ages 1 to 7 years completed an online survey containing items from the Caregiver Feeding Styles Questionnaire, the Relationship Structures Attachment Questionnaire, and the Parent Attitudes About Food Questionnaire. As well, they logged the amount of fruits and vegetables their child ate over a 1-week period. The results of the multiple regression analysis revealed an overall significance which suggested that the 3 parent factors together predicted the amount of fruits and vegetables that children ate; however, closer examination indicated that only parents' attachment style was a significant prediction of children's consumption of fruits and vegetables. The results of the study add to our understanding of the role that parents play in their children's eating habits and the influence of attachment on children's consumption of a nutrient-dense diet.

The current research considered parent report of sleep problems in children with an intellectual disability (ID). Of specific interest were parents who reported child sleep issues/disturbances but who did not consider their child to have a sleep problem. Also of interest was the use of a general parent-training program to treat both the sleep and behaviour problems in children with an ID. Study 1 examined parent perceptions regarding sleep in children with an ID. Parents who reported a child sleep problem provided information on the types of sleep treatment tried and rated their effectiveness. Overall, 243 questionnaires were completed by parents of children with a range of disabilities aged between 3.1 to 18.7 years. While 62% of parents rated their child as displaying problematic night settling, night waking, early waking, or other disturbing sleep behaviours, only 27% of parents considered their child to have a sleep problem. A higher number of parents (75%) than expected had tried at least one type of intervention, although it was not possible to discern 'self help' treatments from 'professionally sought' treatments. Study 2 investigated child and parent factors associated with parent perception of sleep problems in children with an ID. Seventy-six parents from Study 1 completed measures in relation to child adaptive and daytime behaviour, parent stress, locus of control, personality (extraversion, neuroticism, and psychoticism), parenting competence, and perceived control over the child's sleep and daytime behaviour. Based on parent report on a sleep measure and response to the question 'do you think your child has a sleep problem' parents were allocated into one of three sleep groups: Parents who recognised a sleep problem (RSP, N=20), parents whose child did not have a sleep problem (NSP, N=35), and parents who did not recognise their child to have a sleep problem (USP, N=21). The results revealed differences between parents who do (RSP) and parents who do not (USP) recognise their child's sleep problem. These differences related to amount of child sleep (as reported by parents) and parent perceived control over the child's sleep and daytime behaviour. Study 3 examined the efficacy of a general parent-training (behaviour management) program, with sleep used as the training exemplar, for the treatment of sleep problems in children with an ID. Of the 20 parents in the RSP group in Study 2, five agreed to take part in Study 3 and three completed the intervention. The effect of the intervention on (a) a targeted sleep problem, (b) a targeted behaviour problem, (c) other sleep and daytime behaviours, (d) parent stress, (e) parent sleep, (f) parent sense of competence, and (g) parent perceived control over the child's sleep and daytime behaviour were examined. All parents reported an improvement in target sleep behaviour, and at follow-up all of the parents no longer considered their child to have a sleep problem. One parent reported a decrease in stress and an increase in measures of perceived control, and parenting competence, while two parents showed minimal to no improvement on child and parent outcomes.
