  • the Life Trajectory interview for youth lti y method development and psychometric properties of an instrument to assess Life course models and achievement
    International Journal of Methods in Psychiatric Research, 2006
    Co-Authors: Ryan Andrew Brown, Carol M Worthman, Jane E Costello, Alaattin Erkanli
    Abstract:

    This paper describes the rationale, development and psychometric properties of the Life Trajectory Interview for Youth (LTI-Y), an instrument designed to assess cognitive models of the Life course and Life-course achievement. This method was developed over 13 months of pilot research, and applied with a population of 350 participants from the Great Smoky Mountain Study, a longitudinal epidemiological study of mental health in western North Carolina comprising 1420 youths (among them 350 Cherokee Native Americans). The LTI-Y is designed to address gaps in our understanding of the links between large-scale structural conditions and social processes and individual outcomes such as mental health. Scale consistency (n = 350) was good to high, whereas test-retest reliability in a limited sample (n = 18) was moderate to good, depending on the domain and dimension of data considered. Overall, psychometric properties indicate fairly stable and consistent Life-course strategies and priorities. Although developed and piloted with youth from Western North Carolina, the methods described could be applied to any population of interest. Copyright © 2006 John Wiley & Sons, Ltd.

  • Youth and young adult suicide: a study of Life Trajectory.
    Journal of psychiatric research, 2011
    Co-Authors: Monique Séguin, Johanne Renaud, Alain Lesage, Marie Robert, Gustavo Turecki
    Abstract:

    Abstract Objectives Explore the unique developmental challenges and early adversity faced by youth and young adult who died of suicide. Method Sixty-seven suicide victims (SG) were compared with 56 living control with no suicidal ideations in the last year, matched for age, gender, and geographical region. Mixed methods were used: consensus DSM-IV diagnoses were formulated based on Structured Clinical Interview for DSM-IV (SCID)-I and -II interviews complemented by medical charts. Life calendar method was conducted with closest third party informant. Life-history calendar served to measure Life events and adversity throughout the Life course and were analyzed by attributing burden of adversity score per five-year segment, which was then cluster-analyzed to define suicide victim profiles. Results During the last year, mood disorders, abuse and dependence disorders, and anxiety disorder were between 8 and 63 times more likely to be present in the suicide group. Between 0 and 4 years old, 50% of children in the SG were exposed to abuse, physical and/or sexual violence; 60% between 5 and 9 years old; and by the time they were 10–14 years old, 77% were exposed to these forms of violence. In the control group, the respective figures were 14%, 18% and 34%. In the suicide group, the trajectories leading to suicide are different as we observe two different subgroups, one with early-onset and one with later-onset of adversity. To a large extent, people in the suicide group were exposed to major adversity and they were more likely to present cumulative comorbid disorders.

  • Life trajectories and burden of adversity: mapping the developmental profiles of suicide mortality
    Psychological medicine, 2007
    Co-Authors: Monique Séguin, Alain Lesage, Gustavo Turecki, Mélanie Bouchard, Nadia Chawky, Nancy Srt Tremblay, Andrée Guy
    Abstract:

    Background. Little is known about differential suicide profiles across the Life Trajectory. This study introduces the Life-course method in suicide research with the aim of refining the longitudinal and cumulative assessment of psychosocial factors by quantifying accumulation of burden over time in order to delineate distinctive pathways of completed suicide. Method. The psychological autopsy method was used to obtain third-party information on con- secutive suicides. Life-history calendar analysis served to arrive at an adversity score per 5-year segment that was then cluster-analysed and correlated to define victim profiles. Results. Two distinct Life trajectories emerged : (1) individuals who experienced childhood traumas, developmental adversity and little protection were more likely to present concurrent psychiatric and Axis II disorders ; and (2) individuals who experienced less adversity but seemed more reactive to later major difficulties. Conclusions. The Life calendar approach presented here in suicide research adds to the identification of Life events, distal and recent, previously associated with suicide. It also quantifies the burden of adversity over the Life course, defining two distinct profiles that could benefit from distinct targeted preventive intervention.
