Interests

Dr. Starr’s Research Interests 

My interests follow several interrelated pathways. Below are brief descriptions of each, followed by a few representative publications (for a full list of publications and links to full text, click here).

Internalizing Disorders & Interpersonal Functioning

Depression and anxiety disorders do not exclusively occur “within the skin;” they markedly influence and are influenced by interpersonal relationships and the social environment. Internalizing disorders predict a range of problematic interpersonal behaviors (e.g., self-generation of interpersonal stressors, excessive reassurance seeking, deterioration of friendships and romantic relationships, co-rumination, etc.), and in turn, interpersonal problems are potent predictors of internalizing disorders—potentially leading to a vicious cycle that perpetuates risk. My research attempts to capture these reciprocal processes.

Genetic Factors in Internalizing Disorders

Genes clearly play an important role in the etiology of internalizing disorders, but they don’t seem to operate independently of the environment. Much of my recent research has explored interactions between specific genetic variants and environmental conditions, in predicting either depressive symptoms or related processes (e.g., stress generation). I am interested in identifying traits, behaviors, or cognitive processes that serve as intermediate phenotypes that explain the association between genetic risk factors and internalizing outcomes. More recently, I also have developed an interest in examining other physiological predictors of stress regulation (e.g., neuroendocrinological).

Comorbidity of Anxiety and Depression

Anxiety and depression co-occur at rates far surpassing chance. This simple observation has left an indelible mark on psychopathology research, leading many to question whether the two constructs can be legitimately differentiated. My research examines several questions related to comorbidity, including whether it is better represented by shared transdiagnostic components and how it can function as a confounding variable in research. I am especially interested in identifying mechanisms of comorbidity, especially in applying causal models. Previous research suggests that anxiety disorders tend to temporally precede depression, and in a previous daily diary study (Starr & Davila, 2012, Behaviour Research and Therapy), I found the same pattern holds for anxious and depressed moods. One possible explanation is that anxiety symptoms may trigger depressogenic processes (such as anxiety-focused rumination or interpersonal problems) that increase risk for subsequent symptoms and disorders of depression. For example, some of my previous research has examined the potential mediating or moderating roles of anxiety-focused rumination and interpersonal problems.

Methods

My research uses a variety of methodological approaches, but I am particularly interested in applying daily diary and experience sampling methods to understand micro-processes that contribute to internalizing disorder etiology.
