Effectiveness of brief time-out with and without contingent delay: a comparative analysis.

Lord et al. (1986) asked a simple question: does adding a delay before a child can leave time-out make the punishment stronger?

They worked with three children who hit or disrupted class. Each child went through an ABAB reversal. In one phase, time-out ended after a short fixed period. In the other, the child had to sit quietly for an extra 30 seconds before release.

The team measured aggression and disruption across both versions.

Both styles of brief time-out cut problem behavior. Adding the 30-second quiet rule did not give any extra benefit.

The authors concluded that a simple, fixed-length time-out works just as well as one with a release contingency.

Amore et al. (2011) ran almost the same comparison 25 years later with preschoolers and got the same answer: release contingencies add no clear value. This is a clean conceptual replication.

Leander et al. (1972) had earlier shown that 15-minute and 30-minute time-outs work equally well, hinting that longer is not always better. Lord et al. (1986) now show that fancier release rules are not better either.

Capio et al. (2013) extended the idea by letting kids shorten their own time-out if they comply fast. That twist did boost compliance, but the basic behavior-reduction power stayed the same. Together, these studies draw a clear line: keep time-out short and simple unless you have a specific compliance goal.

You do not need extra rules or longer sits for time-out to work. Pick a brief, fixed interval and start teaching replacement skills right away. This saves staff time, reduces escalation, and keeps the procedure easy for everyone to follow.
