Sandile cleans his bedroom 4 times

a day. Each time he leaves his house, he checks if he has locked the main door

at least 4 times because “crime is an issue” in his neighbourhood. Sandile has

had to replace his vehicle door handles 2 times in the past 24 months because each

time he parks his car, he rounds it 5 times to check if all the doors are

locked because “he does not want to leave anything to chance”. Sandile finds

his repetitive acts stressful, yet he cannot help but do them to feel at ease. Sandile

is most likely to receive a diagnosis of------------.
