Daily Manifestations of Psychopathology in Response to Stress

Psychological functioning is shaped by how people navigate their environment. Accordingly, psychopathology is often caused and maintained by patterns of responding to the environment that do not meet situational demands. In particular, psychopathology is often expressed in an inflexible or intense manner of coping with stressful situations. Prior research on psychopathology and daily life stress is limited by an overreliance on negative affect reactivity, which neglects the myriad responses that can create problems in a person’s life. In this study, we assessed a broad range of daily manifestations of psychopathology to examine daily psychopathology– stress associations. We conceptualized individual differences in functioning as psychopathology traits and daily fluctuations in the interrelated thoughts, behaviors, and emotions as psychopathology states, with traits and states corresponding to the same domains of functioning (i.e., antagonism, detachment, disinhibition, negative affectivity, anankastia, psychoticism). Data have been taken from two samples enriched for psychopathology (N= 112, N= 294 participants) who completed daily assessments of stressors and psychopathological states (n= 9,201, n= 4,292 days). We used multilevel structural equation models to examine average, within-person associations between stressors and psychopathological states and correlations between psychopathological traits and stress responses. Results showed that (a) most people experience increases in psychopathological states when stressed and (b) psychopathological traits relate to more consistent and stronger increases in psychopathological states. Our study suggests that psychopathology reflects how people cope with stressful situations, and what distinguishes people with high-trait psychopathology from those who experience typical upticks in psychopathology when stressed is the consistency and extremity of their responses.
