This investigation tests the theory of planned behavior (TPB) as a predictor of HIV testing intention among Nigerian university undergraduate students.
A cross-sectional study of 392 students was conducted using a self-administered structured questionnaire that measured socio-demographics, perceived risk of human immunodeficiency virus (HIV) infection, and TPB constructs. Analysis was based on 273 students who had never been tested for HIV. Hierarchical multiple regression analysis assessed the applicability of the TPB in predicting HIV testing intention and additional predictive value of perceived risk of HIV infection.
The prediction model containing TPB constructs explained 35% of the variance in HIV testing intention, with attitude and perceived behavioral control making significant and unique contributions to intention. Perceived risk of HIV infection contributed marginally (2%) but significantly to the final prediction model.
Findings supported the TPB in predicting HIV testing intention. Although future studies must determine the generalizability of these results, the findings highlight the importance of perceived behavioral control, attitude, and perceived risk of HIV infection in the prediction of HIV testing intention among students who have not previously tested for HIV.
本研究检验计划行为理论（TPB）作为尼日利亚大学生艾滋病毒检测意愿预测指标的有效性。
采用自填式结构化问卷对392名学生进行横断面研究，问卷内容包括社会人口统计学信息、对人类免疫缺陷病毒（HIV）感染的感知风险以及TPB相关变量。分析基于273名从未进行过HIV检测的学生。采用分层多元回归分析评估TPB在预测HIV检测意愿方面的适用性以及HIV感染感知风险的额外预测价值。
包含TPB相关变量的预测模型解释了HIV检测意愿35%的变异，其中态度和感知行为控制对意愿有显著且独特的贡献。HIV感染感知风险对最终预测模型的贡献较小（2%）但具有显著性。
研究结果支持TPB对HIV检测意愿的预测作用。尽管未来研究需确定这些结果的普遍性，但研究结果凸显了感知行为控制、态度以及HIV感染感知风险在预测从未进行过HIV检测的学生的HIV检测意愿方面的重要性。
