This study has investigated whether the succes of the toilet training in children between 1.5 and 4 years old is related tot parenting style, child temperament, child age at start and use of a specific method for toilet training. The specific method was an app, called ‘De Pot Op’, which gave parents guidance in the process of toilet training in a rapid of gradual manner. The study had a retest-posttest RCT design with random assignment to the experimental group, which used the method, or the control group, which designed the toilet training in its own way. The sample consisted of 99 participants who completed a questionnaire about parenting and temperament before the start of the toilet training. After two weeks the participants were asked if their child was toilet trained. Although the factors investigated were expected to have an nfluence, no factor was found to be significantly related to toilet training success. Age did seem to have some effect: The children who were toilet trained after two weeks were significantly younger at the start of toilet training than the children who were not yet toilet trained after two weeks. Also, the use of the 'De Pot op' method seemed promising. Temperament, parental parenting style and starting age had no direct influence. Limitations such as a homogeneous sample and possible measuring instrument biases may have influenced the results. This study provides valuable insights for future research, such as the impact of socioeconomic status and more personalized toilet training methods.Show less
