  • My research involves the intensive scientific/clinical study of individuals, particularly those with comorbid depression and anxiety, and focuses on developing clinical case formulations and treatment plans within a cognitive-behavioral-interpersonal framework. We use a semi-structured clinical interview assessing issues and events of clinical relevance to the individual along with data from standardized measures to develop a cognitive behavioral case formulation (CBCF). The formulation may include cognitive-behavioral-interpersonal scenarios and idiosyncratic cognitive schema. The former are situation specific prototypical sequences of thoughts, feelings, behaviors, and interpersonal interactions that are distressing to the individual (Mumma & Smith, 2001). The latter involve core beliefs, assumptions, and rules, along with associated automatic thoughts, that are specific to an individual and his or her life context and that may be important in generating and maintaining distress (e.g., Clark & Beck, 1999; J. Beck, 2011; Persons, 2008). The CBCF "fine tunes" the focus of "manualized" cognitive-behavioral therapy (e.g., for depression) or is used to develop an individualized treatment plan for complex or comorbid cases (for whom standardized treatments may not be available). We have been developing person-specific, intensive longitudinal methods for scientifically validating CBCFs (e.g., Mumma, 2004, 2011; Mumma, Marshall & Mauer, 2018; Mumma & Fluck, 2016; Mumma & Mooney, 2007a, b), an area in which there has been surprising little research despite the importance of the CBCF in cognitive therapy. We also have studies a) examining the sensitivity and intraindividual psychometric properties of measures (of distress, dysfunction, and thoughts/beliefs) that are idiographic (tailored to a particular person's life situation and experiences); and b) investigating the efficacy of manualized and tailored cognitive-behavioral treatment for adult ADHD individuals with comorbid disorders. Finally, a more recent theme in our research group is the incremental assessment and treatment utility of intraindividual dynamic network analysis to understand the temporal dynamics between facets of an individual's functioning over time (e.g., David, 2019; David, Marshall, Evanovich, & Mumma, 2018; Thornton, 2019). Our studies typically involve data collection at multiple points in time, using ecological momentary assessment methods.

Clinical Interests

Assessment and treatment of adults with co-morbid mood and anxiety disorders such as comorbid major depressive episode and obsessive compulsive disorder or generalized anxiety disorder. I specialize in patients with chronic and severe disorders, many of whom have not responded to standard outpatient pharmacological or psychological treatment, have relapsed, or have been hospitalized. I use intervention components from standardized cognitive, behavioral, and/or interpersonal treatments along with theory-based interventions, all of which are integrated into an individualized or tailored treatment plan via the cognitive-behavioral case formulation.

Student Research:
Ongoing studies by graduate students in the lab focus on using ecological momentary assessment methods to validate and test cognitive-behavioral case formulations (with K. Katuls; C. Mauer; C.Thornton) evaluating the intraindividual psychometric properties of idiographic (individually tailored) measures of distress (depression, anxiety, anger) and cognitive schema, using intraindividual dynamic network analysis in the assessment and treatment planning for adults with anxiety, OCD, and mood disorders, and on cognitive-behavioral interventions for adults with ADHD.
