 Triple P – Positive Parenting Program - two to four years later: The moderating roles of experiencing a stressful event and obtaining subsequent parenting services 
The long-term moderators of evidence-based parenting support programs are still poorly understood. The aim of the present study is to examine whether, two to four years later, the maintenance of Triple P achievements in various aspects of parenting is affected by two moderators that may occur in families, which are (1) a negative stressful event (NSE) or (2) other child or parenting support services. The results of the study conducted among 164 parents of children aged 0-12 during the program showed that most of Triple P’s achievements were stable over time, regardless of an adverse context or the use of subsequent services. Experiencing a NSE was also found to be in favor of the maintenance of certain parenting skills, and obtaining subsequent services was associated with parental stress. These results provide thought regarding the mobilization of social support in families following a NSE and the associations between parental stress and service use.
