<P> Research on the influence of guilt indicates that it plays an important role in the effectiveness of the DITF technique . Participants began the study by filling out a questionnaire related to demographics and health . The experimenter then told the participant he or she was finished with the experiment . As the participant was leaving, the experimenter asked the participant to record meals for the next three months as a part of a larger study on health . After refusal, the experimenter then made a second smaller request for the participant to record their meals for four days . There was a control condition that only received the second smaller request . Participants were assigned to one of four groups: high guilt induction and high guilt reduction, high guilt induction and low guilt reduction, low guilt induction and high guilt reduction, and low guilt induction and low guilt reduction . The high guilt induction statement indicated that the rejection of the first request would have negative effects on the study, while the low guilt induction statement indicated that the rejection of the first request would not really have negative effects on the study . The high guilt reduction statement indicated that the second request would be equally helpful as the first, while the low guilt reduction statement indicated that the second request would not be as helpful as the first . Researchers measured both verbal and behavioral compliance to the smaller second request . Findings indicate a significant increase in both types of compliance for the high guilt induction, high guilt reduction condition . There was no DITF effect for the other conditions because compliance to the second request was the same as compliance for the control condition . According to the researcher, this suggests that guilt is the sole explanation for the effectiveness of the DITF technique . </P> <P> In a study looking at the DITF technique, researchers found that DITF requests that required metacommunication in the responses had higher rates of compliance than requests that did not . The researchers define metacommunication as establishing social boundaries . This is important because the DITF technique often involves strangers making extreme requests, which might elicit a response that requires metacommunication . For example, a person may use metacommunication to indicate that it is inappropriate for a stranger make such an extreme request . This study included four different groups: one starting with a large request and including a metacommunicative statement, one starting with a large request and excluding a metacommunicative statement, one with only a smaller request and including a metacommunicative statement, and one with only a smaller request and excluding a metacommunicative statement . For all of the groups a confederate asked participants to fill out a questionnaire about campus activities . The large request required a few hours, while the smaller one required 20 minutes . In the groups that started with a large request, the confederate followed up with the smaller one after a refusal . The requests with metacommunication included a sentence stating, "This is kind of awkward . There is something else I'd like to ask of you, but tell me if even this seems inappropriate between strangers" prior to filling out the 20 - minute questionnaire (p. 92). Results show significantly greater compliance to requests that included the metacommunicative statement . The researchers suggest that the explicit statement regarding social boundaries makes participants comply to avoid engaging in metacommunicative conflict . </P> <P> Research investigating reverse psychology showed that participants used the DITF technique in their everyday lives . They also use other reverse psychology tactics, such as FITD . There were two studies that looked at participants' own experiences using reverse psychology, which these researchers refer to as strategic self - anticonformity . The first study consisted of an open - ended questionnaire that asked participants about instances in which they used strategic self - anticonformity . The second study asked about specific instances of different types of strategic self - anti-conformity, like DITF and FITD . Findings indicate that most of the participants could provide examples of their own use of reverse psychology tactics and that a likely explanation for this is a need for social reassurance . </P> <P> A study looking at behavioral, not just verbal, compliance to donate money found that the DITF technique was effective . The study involved male and female confederates who ordered lemonade at a restaurant and engaged in conversation before the male announced loudly that he was leaving to buy a part for his bicycle . After he left the female confederate expressed aloud that the male did not pay and asked the participant sitting near her to pay the total bill . In the DITF condition, the female confederate asked if the participant would pay part of the bill after a refusal to pay the total bill from every participant . In the control condition the female confederate only made the second smaller request . The DITF technique yielded significantly more behavioral compliance than the control, which shows that the DITF technique works for more than just verbal agreement . </P>
