Child maltreatment in stepfamilies : the impact of mother's dating behaviour

This thesis explored the relative utility of evolutionary and ecological theories to understand under which conditions children in non-biological families are most at risk of childmaltreatment.  The study revealed that single-mothers have complex needs and stressors, which may increase their vulnerability and impact on decisions made in selection of partners.

Second families...first class. The experience of stepfamilies in Australia

Second families…first class explored stepfamilies in Australia and the difficulties they experience. The areas that caused higher levels of difficulty were legal and financial issues; and dealing with former partners. However, the findings also indicated many areas that provide few difficulties and many adults who are satisfied with stepfamily life.

Lesbian family disclosure: Authenticity and safety within private and public domains

Definitions of family and disclosure of family configuration are important themes for understanding the experiences of contemporary lesbian-parented families. Drawing on multi-generational family interviews with 20 lesbian-parented families in Victoria, Australia, we explore how participants describe and present their families in public contexts. We found a marked difference in experience between lesbian-parented stepfamilies and lesbian-parented de novo families where children are conceived and raised by lesbian parents from birth. Family members adopted a variety of strategies when disclosing parents’ sexual orientation in mainstream social institutions such as health care settings and schools. Some chose a proud, open strategy; while others were more private; yet others chose a passive strategy, particularly when dealing with health care providers, and a selective strategy when dealing with schools. These strategies demonstrate
the fine balance that families must strike between being publicly authentic and creating safety by protecting themselves from negative attitudes.

Child-related information processing in step-parents : investigating the Cinderella effect

This thesis examined the over-representation of step-parents as perpetrators of child physical abuse. Results suggested a number of differences between step- and biological parents in attachment, information-processing, and disciplinary practices. Results were used to formulate a model of step-parental abuse, which has potential implications for the prevention of child physical abuse. The professional portfolio presents four cases from forensic practice in which predictions about further criminal behaviour are made. These cases are then used to discuss several practical questions that may be posed by psychologists who are considering which approach (clinical or actuarial) to use.

Family dynamics and the risks for child maltreatment of stepchildren

The thesis examined systemic factors that placed children in stepfamilies at greater risk of physical abuse and neglect by comparing differences between biological- and step-families on a number of known risk factors. A model describing the pathway of child abuse and neglect for children living in stepfamilies was developed to aid in prevention.The portfolio presents four case studies which demonstrate the impact of disruptions to attachment experiences and the sequelae on psychological functioning and how the associated affect dysregulation may be linked to attachment disruptions.

Child AD/HD severity and psychological functioning in relation to divorce, remarriage, multiple transitions and the quality of family relationships

Both Attention-Deficit/Hyperactivity Disorder (AD/HD) and divorce are very prevalent in western societies, and they may occur together. AD/HD is generally viewed as a neurobiological disorder, which has led to a commonly held belief that social-environmental factors play little role in the symptom profile of children diagnosed with the disorder. This study investigated the association between parental divorce, remarriage, multiple transitions, the quality of relationships with family members and the psychological well-being of children and adolescents with AD/HD. First, differences in children’s AD/HD symptom profiles in relation to parents’ divorce status (single/multiple divorce) and family composition (single parent/stepfamily) were examined. Second, the association between the quality of children’s relationships with each family member and parents’ marital status (divorced/non-divorced) and family composition was investigated. In addition, age, gender and AD/HD subtype differences were assessed. Third, the association between the quality of children’s interactions with family members and children’s AD/HD symptom profile was explored. No significant differences in children’s behavioural profiles were found in terms of parents’ divorce status. Living in stepfamilies was associated with greater AD/HD severity and social malfunctioning. Disruptive parent–child and sibling relationships were found to be related to children’s age, gender, AD/HD subtype and parents’ marital status. Further, poor interactions with family members correlated with children’s AD/HD severity and psychological well-being. In summary, divorce, remarriage and the quality of relationships with family members are important correlates of the symptom profile of children with AD/HD, and this emphasises the need for special treatment modules for these families.
