The aim of this study is to contribute to the understanding of motivations for cross-generational relationships and how the perception of risk of acquiring sexually transmitted infections (STIs) including HIV affects condom use in Kenya. Eight focus-group discussions were conducted with women and 28 interviews were held with men in four Kenyan towns. Ethnograph 5.0 computer software was used for the analysis of data. Women's primary incentive for engaging in such relationships is financial; men seek sexual gratification. Pressure from peers compels women to find older partners. Although some peers encourage such relationships, other groups, especially wives, same-aged boyfriends, and parents, disapprove of them. Couples are preoccupied by the threat of discovery. STI/HIV risk perception is low, and couples rarely use condoms. Material gain, sexual gratification, emotional factors, and recognition from peers override concern for STI/ HIV risk. Women's ability to negotiate condom use is compromised by age and economic disparities. Programmatic strategies include communicating information about such relationships' STI/HIV risk, promoting consistent condom use, decreasing peer pressure to pursue such relationships, and improving women's access to alternative sources of income.

The objective of this study was to identify a set of scales for summarizing the results of the Center for Marital and Sexual Health Sexual Functioning Questionnaire (CMASH SFQ). Scales for this instrument were constructed using patients' responses to the CMASH SFQ in a recent clinical trial of prostaglandin E1 (PGE1, alprostadil), an injectable vasodilator used to treat erectile dysfunction. A set of items was identified as a scale if they met predetermined standards of internal consistency, discriminant validity, and convergent validity. The reproducibility of the scales was then evaluated, and the extent to which the scales reliably measured change in treatment-related quality of life was assessed. Reliable and responsive scales for four domains related to sexual functioning were identified. Items in these scales were generally internally consistent; items in the scales and the scores for the scales generally satisfied criteria of discriminant validity; and the scales generally satisfied the standard for convergent validity. Evaluating patients' responses to the CMASH SFQ with scores for four reliable and responsive scales allows easier summarization of patients' sexual functioning and increases the statistical power of evaluations of the effects of interventions designed to improve sexual functioning.
