A Brief Measure of Situation Characteristics Based on the Lexical Approach: Validation of the Situation Six Brief Scale

Following the well-established field of personality measurement, the measurement of psychological situations has become increasingly important. Their assessment, however, often relies on lengthy instruments that are difficult to use in repeated-measurement and other time-constrained research designs. We developed and validated the Situation Six Brief Scale (SSBS), a 12-item measure of the six dimensions of the lexically based Situation Six taxonomy: Negativity, Positivity, Familiarity, Demandingness, Oddness, and Straightforwardness. Each dimension is assessed with two items, each item combining three adjectives. In two preregistered studies with UK participants recruited via Prolific, we examined the SSBS’s reliability, factor structure, and construct validity. In Study 1 (N = 267), a confirmatory factor analysis supported the hypothesized six-factor structure. The SSBS dimensions showed strong convergence with the corresponding dimensions of a longer Situation Six scale, and largely replicated its pattern of associations with the DIAMONDS situation characteristics and affective states. In Study 2 (N = 280), the six-factor structure was further replicated, and the scale was sensitive to experimentally manipulated situation descriptions relative to a personally recalled baseline situation. Overall, the findings support the SSBS as a brief, valid measure for efficient assessment of situation characteristics.
