I am currently working in Daniel Capron’s Anxiety and Trauma Research Lab at the University of Southern Mississippi with the purpose of studying how thought processes (such as repetitive negative thinking, control of thoughts), cognitive biases, and sensitivities (i.e. anxiety, depression sensitivity) relate to suicidal ideation and risk for suicide.

We examined the relationship between age and history of suicide attempt on borderline traits, depressive rumination, aggression, memory performance, and language fluency.
We examined decision-making outcomes in early-onset (those with suicidal behavior early in life) vs. late-onset (those who first suicide attempt occured late in life) attempters.
We are exploring how different forms of childhood trauma (abuse, neglect) may relate to age of onset of first suicidal behavior.
We combined numerous factors that are said to be protective against depression in late life (mindfulness, social support, life engagement, etc.) to see if they would relate to presence or severity of suicidal ideation, or likelihood of past suicide attempt.
My master’s thesis will examine different forms of rumination (angry, depressive, suicidal), and their relationship with thought control and suicidality.
I am examining the relationship between anxiety, depressive, and suicidal sensitivities, as well as how they relate to thought control and suicidality.
We examined the trajectory (changes) in suicidal ideation over months to years and examined risk factors and outcomes associated with each type of trajectory.
Background: Studies of risk factors for suicidal behavior are typically restricted to narrow age ranges, making it difficult to determine if they have the same relevance or potency across the full adult lifespan.
Methods: This study examined selected clinical and neurocognitive risk factors for suicidal behavior – borderline personality traits, aggression, depressive rumination, memory performance, and language fluency– in a multi-site sample (N = 309, ages 16–80) of depressed patients with a recent (last 5 years) suicide attempt or no history of attempt, and demographically similar non-psychiatric controls. We examined cross-sectional age and attempter/non-attempter differences on these risk factors, and whether certain risk factors were more prominent discriminators of past suicide attempt earlier or later in the lifespan. Correlations with age were computed, and logistic regression was used to classify attempter status based on each risk factor and its interaction with age.
Results: Nearly all risk factors were negatively correlated with age. Borderline traits, aggression, memory, and category fluency each predicted attempter status (p < 0.05), but these effects were not different across ages. In contrast, the association between rumination and suicide attempt status differed across the lifespan, becoming a stronger discriminator of past suicidal behavior at older ages.
Limitations: The cross-sectional design limits our developmental findings.
Conclusions: Despite age-related changes in symptom severity or neurocognitive performance, key risk factors for suicidal behavior previously identified in studies with more restricted age-ranges are salient throughout the adult lifespan. In contrast, depressive rumination may be particularly salient in later life.
Background: People who have attempted suicide display suboptimal decision-making in the lab. Yet, it remains unclear whether these difficulties tie in with other detrimental outcomes in their lives besides suicidal behavior. We hypothesize that this is more likely the case for individuals who first attempted suicide earlier than later in life.
Methods: A cross-sectional case-control study of 310 adults aged ≥ 50 years (mean: 63.9), compared early- and late-onset attempters (first attempt < 55 vs. ≥ 55 years of age) to suicide ideators, non-suicidal depressed controls, and non-psychiatric healthy controls. Participants reported potentially avoidable negative decision outcomes across their lifetime, using the Decision Outcome Inventory (DOI). We employed multi-level modeling to examine group differences overall, and in three factor-analytically derived domains labeled Acting Out, Lack of Future Planning, and Hassles.
Results: Psychopathology predicted worse decision outcomes overall, and in the more serious Acting Out and Lack of Future Planning domains, but not in Hassles. Early-onset attempters experienced more negative outcomes than other groups overall, in Lack of Future Planning, and particularly in Acting Out. Late-onset attempters were similar to depressed controls and experienced fewer Acting out outcomes than ideators.
Limitations: The cross-sectional design precluded prospective prediction of attempts. The assessment of negative outcomes may have lacked precision due to recall bias.
Conclusions: Whereas early-onset suicidal behavior is likely the manifestation of long-lasting decision-making deficits in several serious aspects of life, late-onset cases appear to function similarly to non-suicidal depressed adults, suggesting that their attempt originates from a more isolated crisis.
