The effects of self-reinforcement and peer-reinforcement on the practice of breast self-examination.

Four months after learning breast self-examination (BSE), 169 sorority women assigned to one of three conditions (No Reinforcement, Self-Reinforcement or Peer-Reinforcement) were compared on BSE frequency subsequent to the training. Participants in both of the reinforcement conditions had agreed to a specified reward after each month's BSE, which was either self-delivered (Self-Reinforcement condition) or delivered by a partner (Peer-Reinforcement condition). Analysis of covariance revealed a significant difference among conditions and a Newman-Keuls test demonstrated that participants in both reinforcement conditions reported more months of BSE than those in the No Reinforcement condition. Furthermore, anxiety during BSE training was negatively correlated with BSE during the follow-up period. These results suggest that BSE, like other behaviors, is influenced by perceived support or rewards and by anxiety, and that BSE intervention programs should be designed with these findings in mind.

The effect of type of relationship on perceived psychological distress in women with breast cancer.

Participants (N = 207) read one of three descriptions of mastectomy patients and then completed the Profile of Mood States (POMS) as they thought the patient would. The three descriptions were identical except for the type of relationship that the participant was asked to imagine having with the patient. A series of one-way ANOVAs indicated that people responded differently to 5 of the 6 POMS factors and the overall Index of Mood Disturbance depending upon the relationship they were asked to imagine that they had with the patient. These differences were significant. Newman-Keuls tests demonstrated the same pattern of results for each factor--those who imagined that the patient was their mother rated her as experiencing less mood disturbance than did those who imagined that she was a woman they worked with or a well-known public figure. These results suggest that people are able to recognize psychological symptoms associated with breast cancer and mastectomy but may have difficulty perceiving these symptoms in their own mothers.

The effects of message framing and feelings of susceptibility to breast cancer on reported frequency of breast self-examination.

One of two types of pamphlets on breast self-examination (BSE) attitudes and behavior was administered to subjects who were classified as high or low in feelings of susceptibility to breast cancer. Half of the subjects received pamphlets stressing the positive consequences of doing BSE and the other half received pamphlets stressing the negative consequences of not doing BSE. A previous study found negatively framed pamphlets to be superior in BSE promotion and these results were explained in terms of Tversky and Kahneman's framing postulate. The original framing postulate includes characteristics of the decision-maker as well as the type of frame presented, thus, we hypothesized an interaction between pamphlet type and level of susceptibility with the largest effect on the group with low perceived susceptibility who received negatively framed pamphlets. The hypothesized interaction did not occur, nor was there a significant effect for pamphlet type. However, there were significant differences between the BSE performance at follow-up of women who were high or low in perceived susceptibility prior to the intervention. These results are discussed in terms of implications for BSE training in the future, more specifically-the need to consider perceived level of susceptibility as an important subject characteristic that could have a large impact on the effectiveness of training programs.
