Key facts

Loneliness (ONS) score

Loneliness Office of National Statistics score

Each level is indicated using a traffic-light metaphor with written labels, color, position and emojis. For individuals, each item response level is scored on a 0-3 ordinal scale, with hardly ever = 3, occasionally = 2, sometimes = 1, and often = 0. A summary score is calculated by adding the item scores for each item and giving a scale from 0 to 12. A summary score is not calculated if any item scores are missing. For cohorts, mean scores are shown on a 0 to 100 scale. Item scores are multiplied by 100 and divided by 3; summary scores are multiplied by 100 and divided by 12. Mean scores are usually rounded to the nearest whole number [PMID32198234].
