LEVEL B · RESEARCH-ADAPTED MEASURE

Everyday Stress Reactivity Test — IPIP

The item set or construct comes from published research or a public-domain measurement program, but this product form may be shortened, combined, translated, or presented differently from the source administration.

CONSTRUCT

What it measures

Stress Reactivity

FORMAT

What you complete

10-item single-construct self-report

SCORING

How the score is made

Declared Likert items are summed after reverse-keying where specified, then transformed to a 0–100 display scale. The display is a response score, not a population percentile, unless an official lookup conversion is explicitly named.

RELIABILITY

Consistency evidence

Coefficient alpha 0.87, reported by Official IPIP scale key. This is source evidence, not a coefficient recalculated from Inward Atlas users.

VALIDITY

What the evidence supports

The item set or construct comes from published research or a public-domain measurement program, but this product form may be shortened, combined, translated, or presented differently from the source administration. Inward Atlas has not independently established criterion, predictive, or cross-cultural validity for this implementation.

NORMS

How values should be read

No Inward Atlas population norms; displayed 0–100 values are transformed response scores

Source and implementation record

The official IPIP key lists 10 items and reports coefficient alpha 0.87. Inward Atlas preserves item scoring direction, normalizes punctuation and obvious typography, and adds non-normative product interpretation without claiming to administer the proprietary JPI-R.

Limitations shown with the assessment

  • The displayed 0–100 value is a transformed mean-item response score, not a population percentile or probability.
  • This preliminary public-domain IPIP scale measures a construct similar to a JPI-R scale; Inward Atlas does not administer or reproduce the proprietary JPI-R.
  • This is not a screening, diagnostic or treatment instrument for anxiety, depression or any mental-health condition.
  • Self-report can change with context, mood and interpretation. Use the result as a focused reflection prompt rather than a permanent label.

Implementation notes

  • Official key reports coefficient alpha 0.87.
  • 5 positively keyed and 5 reverse-keyed items are preserved.
  • No population percentile or diagnostic threshold is applied.
