Why self-control is hard to measure
Ask people how much self-control they have and most will answer with a story about the last time it failed. The cake, the missed deadline, the unused gym membership. Trait self-control is not that feeling. It is a stable tendency to override impulses and steer behaviour toward longer-term goals, and it shows up across situations rather than in one bad afternoon.
The Brief Self-Control Scale (BSCS) is a short way to put a number on that tendency.
What the 13 items ask
June Tangney, Roy Baumeister and Angie Boone published the full Self-Control Scale in 2004 in the Journal of Personality, together with a 13-item short form. The long version has 36 items. The short form kept the ones that carried the most information.
Each item is a statement about you, rated from 1 ("not at all like me") to 5 ("very much like me"). Nine of the thirteen are worded in the failure direction, things like "I am lazy" or "I have trouble concentrating", and those get reversed before the total is added up. The total runs from 13 to 65, and higher means more self-control.
Where the items came from
Baumeister's strength model treated self-control as a limited resource that tires with use, so the original research looked at the places where that resource gets spent: holding back unwanted thoughts, regulating emotion, restraining impulses, keeping performance up when you do not feel like it, and breaking habits. The thirteen items sample all five.
Later work complicated the story. Trait self-control predicts better outcomes partly because people who score high put themselves in fewer tempting situations in the first place, rather than because they win more fights with temptation. That shift matters when you read your own score: a high total is not a medal for willpower, it usually means the person has arranged their life so that willpower is needed less often.
One factor or two
Tangney and colleagues designed the scale as a single score and recommended using the total. Independent analyses have kept arguing about that. Lindner and colleagues (2015) compared the one-factor and two-factor structures and concluded that the split between "restraint" and "impulsivity" mostly tracks whether an item is worded positively or negatively. Manapat and colleagues (2019) ran an item response theory analysis and found both a one-factor model with correlated residuals (CFI = .985, TLI = .981) and a two-factor model (CFI = .987, TLI = .984) fitting the data, with the two factors correlating at .85. In a Spanish sample of 1,558 adults, Torres-Marín and colleagues (2024) reported that the two-factor version fit better than a single score.
The practical answer: use the total. If you come across a study that reports subscales, check which model it used, because the item groupings differ between them.
Reliability
Internal consistency was .83 and .85 in the two original samples. Across studies using all thirteen items the range runs from .69 to .85. In a Chinese sample of 903 university students, Fung, Kong and Huang (2020) reported alpha of .80 for the thirteen-item version and .81 for an eleven-item version they proposed, with an omega total of .86.
Manapat's IRT analysis gives a sense of which items do the work. The strongest was item 1, "I am good at resisting temptation" (discrimination 3.05). The weakest was item 4, "I say inappropriate things" (0.95), which is the item most likely to be dropped in short forms.
What a score means
There is no clinical cutoff for the BSCS. Research uses median splits or treats the score as a continuous variable. The bands below are a reading aid, not a diagnostic line.
| Total | Reading |
|---|---|
| 52 to 65 | High. Resisting temptation and sticking to long-term goals tends to come easily. |
| 40 to 51 | Middle. Self-control holds in most areas and gives way in specific ones. |
| 13 to 39 | Lower. Impulses win more often. Changing the situation usually beats trying harder. |
For scale, the Chinese validation sample averaged 38.77 (SD = 7.32), with men at 39.33 and women at 38.68. An ordinary student sample sits near the middle of the range, so a mid-range total is the normal case, not a warning sign.
What it tracks
In that same Chinese sample, BSCS totals correlated .46 with self-esteem on the Rosenberg scale, .30 with life satisfaction, .33 with subjective happiness, and -.42 with the GHQ-12, meaning higher self-control went with fewer reported psychological symptoms. The original 2004 paper reported associations with academic performance and with lower rates of binge eating and alcohol problems; those specific figures are not in the source material behind this page, so treat them as directional.
Take the test
The CheckPsych version uses the thirteen original items and takes about 3 minutes. You get a total between 13 and 65, a band, and a short reading of what it suggests.
