The Context Sensitivity Index (CSI): Measuring the Ability to Identify the Presence and Absence of Stressor Context Cues.

The ability to accurately perceive cues to contextual demands across different situations has been identified as a crucial component of successful self-regulation. However, previous attempts to measure context sensitivity have suffered from serious methodological limitations, most notably the possibility that respondents may not possess sufficient knowledge of their own abilities, the confounding of perception of context with response to context, the use of only one or two contextual variations, and the failure to consider the abilities to both accurately detect contextual cues and accurately determine cue absence. This article reports a new, easy-to-administer scenario-based questionnaire measure, the Context Sensitivity Index (CSI), that addressed each of these limitations. The 20-item CSI was iteratively developed and normed using data from five studies to create separate indices to capture sensitivity to the presence of contextual cues (Cue Presence index) and to the relative absence of cues (Cue Absence index). We validated these indices against measures of flexibility, psychopathology, and other scales. Results are discussed in terms of the CSI's implications, limitations, and future applications.
