	3. How to recognize signs of (potential) sexual abuse und how to stop it
	4. How to strengthen a healthy family dynamic
Challenges for the conceptualization and implementation of effective measures	Important factors for the success of a program addressed to parents/guardians are:	Important factors for the success of a program addressed to those working with children are:
	• Interest in the topic	• Interest in the topic	• Media-based campaigns are complex in content and costly to finance
	• Qualification of the prevention educator	• Qualification of the prevention educator
	• Program time-frame (length of training measures and/or independent work)	• Program time-frame (length of training measures and/or independent work)	• Their effectiveness can indirectly depend on the availability of monetary donations
	• Source of referral (Parents put more trust into recommendations by physicians or teachers than those by the media)	• Source of referral (similar to those of parents/guardians)	• Social-marketing campaigns need to be based on solid research with a view towards the target group
Studies to evaluate prevention programs	• Parents who have participated in a program led by qualified educators and have discussed the topic, are in a stronger position to protect a child from sexual abuse [36]	• Programs addressed to teachers have a positive influence on the teachers’ knowledge about the topic [37]	• Up to now, only very few public campaigns on this topic have been assessed [34]
			• Campaigns that focus on specific target groups and topics receive more attention and are therefore more effective [34]
	• Programs which include both parents have consistently proven to be effective [37]. “Home visitations “in high-risk families result in a decrease in the risk of abuse [38]	• People who received training feel in a much stronger position to make a decision not solely based on physical signs; in addition, frequency, duration, intensity, and the professional standards of training measures play an important role [39]
