Consistency of Self-Reports of Sexual Activity among Young Adolescents in Jamaica

Abstract

Context: Adolescents' sexual behavior is an important issue in developing countries and a focus of programmatic efforts for reducing pregnancy and sexually transmitted disease. Yet the accuracy of young people's reports of their sexual activity has rarely been carefully examined. Methods: Data from a three-round longitudinal study of 698 young adolescents in Jamaica were used to examine consistency in the reporting of first sexual intercourse. Adolescents were asked to respond to multiple questions about their first intercourse within each round of the survey, and the items were repeated in subsequent rounds. A multivariate logistic regression analysis was conducted to examine the factors independently influencing the likelihood that adolescents would report their sexual experience inconsistently. Results: The vast majority of respondents (95-100%) reported their sexual experience status consistently within a given survey round. However, when agreement of responses between rounds was examined, 37% of respondents-12% of girls and 65% of boys-responded inconsistently. Multivariate logistic regression analysis indicated that boys were nearly 14 times as likely as girls to report their sexual experience inconsistently. Conclusions: Pervasive inconsistency in the reporting of sexual activity, especially among boys, highlights the limitations of relying on self-reported data to identify sexually active adolescents and to quantify that activity. Using such data to evaluate the impact of interventions designed to delay first intercourse may also be problematic.

Religiosity and Sexual Risk Behaviors Among Latina Adolescents: Trends from 1995 to 2008

“…In self-reported data based on recall, there is always the possibility that responses may have been minimized or inflated by the participants. 42 The measurement of religiosity was limited to items in the dataset. Important aspects of religiosity, such as faith, intrinsic religiosity, and religious well-being, were not assessed; thus, the nature of this construct was not fully captured.…”

Discordance of HIV and HSV-2 biomarkers and self-reported sexual behaviour among orphan adolescents in Western Kenya

“…For example, the majority (95%–100%) of 11-year-old to 14-year-old adolescents in Jamaica responded consistently about first sexual intercourse within each given survey round. However, across three waves of surveys, 37% of respondents—12% of girls and 65% of boys—responded inconsistently about the timing of their sexual debut 17. In a Kenyan study of adolescents aged 12–19 years (49% of whom were sexually active), 20% gave inconsistent reports about lifetime sexual intercourse and timing of first sexual intercourse,16 and in South Africa, 40% of sexually active adolescents inconsistently reported lifetime sexual experience 18…”

The Effect of HIV/AIDS Education on Adolescents in Trinidad and Tobago

“…Self reports were the only method of assessment. Eggleston et al [34] observed that adolescents are not always truthful when providing self reports. Participants were informed that individual responses to the questions would be kept con�dential and would not be shared with classmates, parents, or school authorities.…”
