  • childhood emotional abuse physical abuse and neglect are associated with theory of mind decoding accuracy in young adults with depression
    Psychiatry Research-neuroimaging, 2018
    Co-Authors: Katerina Rnic, Mark A Sabbagh, Dustin Washburn, Michael R Bagby, Arun Ravindran, James L Kennedy, John Strauss, Kate L Harkness
    Abstract:

    Abstract The current study is the first to examine the relation of childhood abuse and neglect history to theory of mind decoding accuracy as moderated by depression. Fifty-five young adults with current or lifetime unipolar depression diagnosis and 70 never-depressed young adults completed the ‘Reading the Mind in the Eyes task,’ (RMET). Childhood emotional abuse, physical abuse, and neglect were assessed with a gold-standard Contextual Interview with standardized, independent ratings. Poorer RMET accuracy was associated with a history of emotional abuse in the depressed group and a history of physical abuse in the non-depressed group. In contrast, across both groups, those with a history of neglect showed significantly enhanced theory of mind decoding accuracy compared to those without. Further, differential accuracy across positive, negative, and neutral valenced stimuli in the RMET was observed in each model. These findings indicate that distinct theory of mind performance results from early experiences of threat versus deprivation, and suggest that early intervention may be most successful in preventing negative interpersonal outcomes of maltreatment by focusing on remediating theory of mind deficits resulting from abuse, and tempering heightened sensitivity in those exposed to neglect.

  • The Relation of Childhood Maltreatment to Psychotic Symptoms in Adolescents and Young Adults With Depression.
    Journal of Clinical Child and Adolescent Psychology, 2014
    Co-Authors: Katherine Holshausen, Christopher R. Bowie, Kate L Harkness
    Abstract:

    This study examined the relation between a history of maltreatment and the presence of psychotic symptoms in a community sample of adolescents and young adults with major depressive disorder. One hundred and twenty-nine depressed adolescents and young adults (M = 16.02 years, 77% female, 92% White) were recruited through community advertisement and clinician referral. Clinical diagnoses and psychotic symptoms (i.e., hallucinations and delusions) were assessed using a structured diagnostic Interview. Childhood maltreatment was assessed using a Contextual Interview and standardized rating system. Logistic regression analyses examined the relation between childhood maltreatment and psychotic symptoms. As hypothesized, individuals with psychotic symptoms were significantly more likely to report a history of severe sexual maltreatment than those without psychotic symptoms (Wald = 5.44, odds ratio = 3.86, p = .020), 95% confidence interval [1.24, 12.01]. Further, those with psychotic symptoms were more likely t...

  • cortisol reactivity to social stress in adolescents role of depression severity and child maltreatment
    Psychoneuroendocrinology, 2011
    Co-Authors: Kate L Harkness, Jeremy G Stewart, Katherine E Wynneedwards
    Abstract:

    This study examined the hypothesis that depressed adolescents with a history of childhood maltreatment will show greater cortisol reactivity to psychological stress challenge than those without, and this relation will be moderated by level of depression severity. Seventy-one adolescents were exposed to the Trier Social Stress Test. Salivary cortisol was assessed at baseline, immediately before the challenge, after the challenge, and during an extended recovery period. Childhood maltreatment was assessed with a rigorous Contextual Interview and rating system. Adolescents with a history of maltreatment produced higher and more prolonged levels of cortisol in response to the challenge than did adolescents with no maltreatment, but only among those with a mild/moderate level of depression severity. Those with moderate/severe depression exhibited a blunted cortisol response regardless of child maltreatment history. These findings indicate that depression is a heterogeneous syndrome, and that both depression severity and child maltreatment history should be considered in studies examining biological stress reactivity.

  • Parental maltreatment, bullying, and adolescent depression: evidence for the mediating role of perceived social support
    Journal of Clinical Child and Adolescent Psychology, 2010
    Co-Authors: Pamela M. Seeds, Kate L Harkness, Lena C. Quilty
    Abstract:

    The support deterioration model of depression states that stress deteriorates the perceived availability and/or effectiveness of social support, which then leads to depression. The present study examined this model in adolescent depression following parent-perpetrated maltreatment and peer-perpetrated bullying, as assessed by a rigorous Contextual Interview and rating system. In 101 depressed and nondepressed community adolescents between the ages of 13 and 18 (M = 15.51, SD = 1.27), peer bullying and father-perpetrated maltreatment were associated with lower perceptions of tangible support and of belonging in a social network. These forms of support mediated the association of bullying and father-perpetrated maltreatment with greater depression severity. In contrast, mother-perpetrated maltreatment was associated with higher perceptions of tangible support.

  • Symptom specificity and the prospective generation of life events in adolescence.
    Journal of Abnormal Psychology, 2009
    Co-Authors: Kate L Harkness, Jeremy G Stewart
    Abstract:

    The purpose of the present study was to uncover patterns in the generation of life events from symptom profiles and specific depression symptoms in an effort to obtain a fine-grained understanding of the stress-generation phenomenon. A community sample of 161 adolescents completed the Beck Depression Inventory-II (A. T. Beck, 1996) at Time 1, and then 88 returned 1 year later for an assessment of life events using a rigorous Contextual Interview and rating system. Consistent with hypotheses, and controlling for baseline stress, cognitive-affective symptoms of depression prospectively predicted higher levels of dependent interpersonal life events. In contrast, somatic symptoms prospectively predicted higher levels of independent life events. Further examination of the types of events generated by specific symptoms suggests that different mechanisms may drive specific patterns of symptom-event generation and suggests that broadening the definition of independence may be necessary to capture the full context of event generation.

  • social cultural and systematic frustrations motivating the formation of a diy hearing loss hacking community
    Human Factors in Computing Systems, 2019
    Co-Authors: Aisling Ann Okane, Abdinasir Aliomar, Rebecca Zheng, Britta F Schulte, Gianluca Trombetta
    Abstract:

    Research on attitudes to assistive technology (AT) has shown both the positive and negative impact of these technologies on quality of life. Building on this research, we examine the sociocultural and technological frustrations with hearing loss (HL) technologies that motivate personal approaches to solving these issues. Drawing on meet-up observations and Contextual Interview data, we detail participants' experiences of and attitudes towards hearing AT that influences hacking hearing loss. Hearing AT is misunderstood as a solution to the impairment, influencing one-to-one interactions, cultural norms, and systematic frustrations. Participants' exasperation with the slow development of top-down solutions has led some members to design and develop their own personalised solutions. Beyond capturing a segment of the growing DIY health and wellbeing phenomenon, our findings extend beyond implications for design to present recommendations for the hearing loss industry, policy makers, and importantly, for researchers engaging with grassroots DIY health movements.

  • Building personas of students accessing a peer-facilitated support for learning program
    Science & Engineering Faculty, 2015
    Co-Authors: Mangalam Sankupellay, Erica Mealy, Christoph Niesel, Richard Medland
    Abstract:

    The modern student represents a change from the traditional learner. More than ever before, additional resources are available online and yet personalised learning and peer-assistance programs are becoming an essential part of tertiary education delivery. This paper presents the first stage in a user-centred design approach to the analysis of the completeness and efficacy of such a personalised, peer-based support for learning program. This approach used an iterative design methodology based on Contextual Interview, workshops and focus groups to develop personas representing students visiting the program. Initial uses of these developed personas have included training of new personnel as well as the evaluation of the program. Overall the use of this user-centred approach and iterative persona development methodology has yielded an invaluable resource for the design of support for learning programs across the higher education industry within Australia and beyond.
