**Abstract**
Psychophysiology tasks are poised to become a major contributor to the NIMH
RDoC initiative, but their psychometric properties must first be well
understood. This study provides a comprehensive evaluation of the temporal
stability, internal consistency, and effect size robustness and stability
of three common tasks within the Negative Valence System.
**Supporting Summary**
The current study provides a comprehensive evaluation of critical
psychometric properties of commonly used psychophysiology laboratory tasks
and measures within the NIMH RDoC. Participants (N = 128) completed the No
Shock, Predictable Shock, Unpredictable Shock (NPU) task, Affective Picture
Viewing task, and Resting State task at two study visits separated by one
week. We examined potentiation and modulation scores in NPU (predictable or
unpredictable shock vs. no shock) and Affective Picture Viewing tasks
(pleasant or unpleasant vs. neutral pictures) for startle and corrugator
responses with two commonly used quantification methods. We quantified
startle potentiation and modulation scores with raw and standardized
responses. We quantified corrugator potentiation and modulation in the time
and frequency domains. We quantified general startle reactivity in the
Resting State Task as the mean raw startle response during the task. For
these three tasks, two measures, and two quantification methods we
evaluated effect size robustness and stability, internal consistency (i.e.,
split-half reliability), and one-week temporal stability. The psychometric
properties of startle potentiation in the NPU task were good but concerns
were noted for corrugator potentiation in this task. Some concerns also
were noted for the psychometric properties of both startle and corrugator
modulation in the Affective Picture Viewing task, in particular for
pleasant picture modulation. Psychometric properties of general startle
reactivity in the Resting State task were good. Some salient differences in
the psychometric properties of the NPU and Affective Picture Viewing tasks
were observed within and across quantification methods.
