This measure assesses implicit positive and negative affect using indirect ratings of neutral, meaningless letter strings. The Implicit Positive and Negative Affect Test (IPANAT) was developed by Fritz Strack and Norbert Schwarz.
Respondents rate the extent to which each stimulus word seems to express specific affective states, yielding separate indices of positive and negative affectivity. It includes 30 items and typically requires about 6 minutes to complete.
The Implicit Positive and Negative Affect Test (IPANAT) is commonly used in research and clinical contexts to complement self-report mood measures, particularly when evaluating affective processes that may be less accessible to conscious awareness or susceptible to impression management. Results are generally interpreted as indicators of implicit affective tone rather than direct reports of current mood.
