Positive and negative affect are the broad feeling states that shape whether a week has felt engaged, energetic, tense, or distressed. This assessment turns that idea into a practical weekly check by asking about ten emotion words and then separating your answers into positive and negative mood totals.

That split matters because real weeks are often mixed. You can feel active, attentive, and determined while also feeling nervous or upset, so a single label like "good" or "bad" often hides the pattern that actually explains how the week unfolded.

The PANAS-SF format is useful when you want a structured snapshot rather than a diary entry. If your Positive Affect score usually sits around 18 to 20 but Negative Affect jumps from 8 to 16 during a deadline-heavy week, the shift points to rising strain even if you still felt productive enough to keep moving.

This tool keeps that snapshot readable by showing Positive Affect, Negative Affect, a combined Total, and an affect balance index (ABI). It also surfaces the strongest negative items and the stronger positive items so you can see which specific feelings were driving the week instead of relying only on a single summary label.

The result is still only a weekly mood snapshot. It does not diagnose depression, anxiety, or any other condition, and a favorable balance score does not mean distress is absent. Use it to notice patterns, compare similar weeks, or bring a more concrete description of your mood to a conversation with a qualified professional if the pattern keeps worsening.

Everyday Use & Decision Guide:

A good first pass is to answer after most of the week is behind you and you can think across ordinary days, not just the last argument, celebration, or poor night of sleep. It works well as a repeatable weekly check-in. It is a poor fit if you want a moment-by-moment mood tracker or a clinical symptom assessment.

People often overread the combined picture and miss the two separate totals. The donut chart is helpful for a quick glance, but the real judgment starts with the Positive Affect and Negative Affect values and then moves to the highest-rated words inside each group.

  • Keep the recall window literal. Answer for the past week rather than for "how I am today" or "how I am in general."
  • If one unusual event dominated the last day or two, make a note of that before comparing this week with an earlier result.
  • Before trusting the summary, scan the response table and make sure no word was rated in haste or left inconsistent with the rest of the week.
  • If the progress bar stalls below 100%, one of the ten emotion words still needs a rating. The result view does not appear until every item is answered.

When the result surprises you, trust the item pattern before the headline. A Positive ABI with several strong negative items usually means the week contained energy and strain together, so the most useful follow-up is to compare next week's Positive Affect and Negative Affect values, not just the ABI label.

Technical Details:

This tool measures affect in two directions rather than compressing mood into one raw total. Five words contribute to Positive Affect and five words contribute to Negative Affect, with each word rated on the same 1 to 5 intensity scale from "Very Slight / Not at all" to "Extremely."

The word set in the tool matches the ten-item short form associated with Thompson's international PANAS work: Alert, Inspired, Determined, Attentive, and Active on the positive side, then Upset, Hostile, Ashamed, Nervous, and Afraid on the negative side. The recall instruction in this tool is the past week, which is consistent with established PANAS time-framing practice.

The tool then derives four numeric summaries. Positive Affect and Negative Affect each run from 5 to 25 once all ten items are answered, Total runs from 10 to 50, and ABI runs from -20 to +20 by subtracting Negative Affect from Positive Affect. The band labels shown by the tool are built-in interpretation aids, not universal clinical cut points, so the raw Positive Affect and Negative Affect values remain the main outputs to trust.

Formula Core:

The scoring is simple addition. Each positive rating is summed into Positive Affect, each negative rating is summed into Negative Affect, and the balance shortcut is the difference between those two totals.

PA = i = 1 xi NA = i = 1 yi Total = PA + NA ABI = PA NA

Rule Core:

After the sums are calculated, the tool assigns plain-language bands. Those bands are deterministic, so boundary values always fall into the same category.

PANAS-SF interpretation rules
Output Rule Meaning in this tool
Positive Affect >= 21 high, 15 to 20 average, <= 14 low Higher numbers reflect more frequent or more intense positive states
Negative Affect <= 10 low, 11 to 15 average, >= 16 high Higher numbers reflect more frequent or more intense distress states
ABI tilt >= 5 Positive, -4 to +4 Balanced, <= -5 Negative Quick shorthand for which side outweighs the other

Processing Notes:

The richer summary panel does more than show the totals. It sorts the five negative items and the five positive items, then lists up to three higher-scored negative drivers and up to three stronger positive items, but only when those items reached at least 3 on the scale. The next-step text also changes with the band pattern, which is why two people with different score combinations can see different follow-up suggestions.

The assessment state is encoded as a ten-character response code using digits 1 to 5 and - for unanswered items. Results appear only when all ten positions are filled, and an invalid response code is ignored rather than partially decoded.

Step-by-Step Guide:

Use the assessment once from start to finish before you compare results across weeks.

  1. Press Begin Assessment. The first emotion word appears, the question list opens, and the progress display starts at 0/10 answered.
  2. Choose one rating for each word from Very Slight / Not at all through Extremely. After each choice, the progress bar advances and the answered item gains a green check mark in the list.
  3. Move through the full set of ten words, using the question list to jump back if you want to revise a response. If the result panel does not appear, look for the item without a check mark and finish that rating first.
  4. When the counter reaches 10/10 answered, the result view opens automatically. Confirm the three main badges: Positive Affect, Negative Affect, and Total.
  5. Read the narrative summary next. Check the ABI and Tilt pills, then compare them with the higher-scored negative words and stronger positive words so you do not reduce the week to one label.
  6. Use the Your Responses table as the final verification step. If one number looks out of character, compare it with the exact item that produced it before deciding the whole week was meaningfully different.

A careful pass gives you a result that is easier to compare over time and easier to discuss with someone else if you need a second view.

Interpreting Results:

The numbers that matter most are Positive Affect and Negative Affect. Total tells you how much affect was reported overall, and ABI is only a shorthand for which side is numerically stronger.

  • Positive Affect >= 21 with Negative Affect <= 10 usually reflects an energetic week with limited distress.
  • ABI from -4 to +4 means the two sides were close together. It does not mean the week was average, calm, or healthy by itself.
  • Negative Affect >= 16 or Positive Affect <= 14 deserves a slower reading, especially if the same high negative words repeat across several weeks.

The main false-confidence trap is assuming that a Positive tilt cancels out high distress. It does not. When a result looks better or worse than expected, verify it against the Your Responses table and the highest-rated words, then look for repetition over time before drawing a bigger conclusion.

Responsible Use Note:

Use this assessment as a self-monitoring prompt, not as a verdict about your mental health. It captures only ten affect words across one week and does not assess functioning, risk, trauma, substance use, or other clinical factors. If Negative Affect stays elevated, Positive Affect stays low, or daily life is getting harder over repeated weeks, bring the pattern and the item-level responses to a qualified professional for a fuller evaluation.

Worked Examples:

Steady, mostly positive week

A person rates the five positive words as 4, 4, 3, 4, and 4, then rates the five negative words as 2, 1, 1, 2, and 1. The tool shows Positive Affect = 19, Negative Affect = 7, Total = 26, and ABI = +12. That lands in average Positive Affect, low Negative Affect, and a Positive tilt, which reads like a productive week with limited distress rather than a week without any stress at all.

High energy, high strain at the same time

Another person answers 5, 4, 4, 4, and 4 on the positive side, then 3, 3, 3, 4, and 3 on the negative side. The result becomes Positive Affect = 21, Negative Affect = 16, Total = 37, and ABI = +5. The ABI still says Positive, but the correct reading is mixed: strong activation plus clearly elevated distress.

Result panel never appears

A user answers nine words, leaving Afraid blank after entering 4, 3, 4, 3, 3, 2, 1, 1, and 2 for the first nine items. The progress display stays at 9/10 answered and there is no Positive Affect, Negative Affect, or Total output yet. Selecting the last rating completes the response code, pushes the progress bar to 100%, and generates the result immediately.

FAQ:

Is this a diagnosis?
No. The tool scores ten mood words across the past week and summarizes them as Positive Affect, Negative Affect, Total, and ABI. Those outputs can help you describe a pattern, but they are not a clinical diagnosis.
Why keep Positive Affect and Negative Affect separate?
Because they do different jobs. You can feel energized and strained in the same week, so two people can share the same ABI while having very different Positive Affect and Negative Affect totals.
What does a Balanced ABI actually mean?
In this tool, Balanced means the ABI falls between -4 and +4. It only means the two totals are close together. It does not tell you whether both totals were low, middle-range, or high.
Why did a prefilled result fail to load?
The response code must contain exactly ten characters, using only 1, 2, 3, 4, 5, or -. If the code breaks that pattern, the tool ignores it instead of loading a partial result.
Do my answers leave the device?
The assessment logic runs in the browser and this tool has no dedicated server-side scoring path. Answers stay in page state and can be represented by the ten-character response code used for URL persistence.
