The study sought to (1) explain intentions to get tested for chlamydia regularly in a group of young people living in deprived areas using the theory of planned behaviour (TPB); and (2) test whether self-identity explained additional variance in testing intentions.
A cross-sectional design was used for this study.
Participants (N = 278, 53% male; M = 17.05 years) living in deprived areas of a UK city were recruited from a vocational education setting. Participants completed a self-administered questionnaire, including measures of attitude, injunctive subjective norm, descriptive norm, perceived behavioural control, self-identity, intention and past behaviour in relation to getting tested for chlamydia regularly.
The TPB explained 43% of the variance in chlamydia testing intentions with all variables emerging as significant predictors. However, self-identity explained additional variance in intentions (ΔR(2) = .22) and emerged as the strongest predictor, even when controlling for past behaviour.
The study identified the key determinants of intention to get tested for chlamydia regularly in a sample of young people living in areas of increased deprivation: a hard-to-reach, high-risk population. The findings indicate the key variables to target in interventions to promote motivation to get tested for chlamydia regularly in equivalent samples, amongst which self-identity is critical.
What is already known on this subject? Young people living in deprived areas have been identified as an at-risk group for chlamydia. Qualitative research has identified several themes in relation to factors affecting the uptake of chlamydia testing, which fit well with the constructs of the Theory of Planned Behaviour (TPB). Identity concerns have also been identified as playing an important part in young people's chlamydia testing decisions. What does this study add? TPB explained 43% of the variance in chlamydia testing intentions and all variables were significant predictors. Self-identity explained additional 22% of the variance in intentions and emerged as the strongest predictor. Indicates key variables to target in interventions to promote regular chlamydia testing in deprived young people.
本研究旨在（1）运用计划行为理论（TPB）解释生活在贫困地区的一组年轻人定期进行衣原体检测的意图；（2）检验自我认同是否能解释检测意图中额外的变异。
本研究采用横断面设计。
从英国一个城市贫困地区的职业教育机构招募参与者（N = 278，53%为男性；平均年龄 = 17.05岁）。参与者完成一份自填式问卷，包括与定期进行衣原体检测相关的态度、指令性主观规范、描述性规范、感知行为控制、自我认同、意图和过去行为的测量。
TPB解释了衣原体检测意图中43%的变异，所有变量均为显著预测因素。然而，自我认同解释了意图中额外的变异（ΔR² = 0.22），并且即使在控制过去行为的情况下，自我认同仍是最强的预测因素。
本研究确定了生活在贫困程度较高地区的一组年轻人定期进行衣原体检测意图的关键决定因素：这是一个难以接触到的高风险人群。研究结果表明了在促进类似样本中定期进行衣原体检测动机的干预措施中应针对的关键变量，其中自我认同至关重要。
关于该主题已知的情况是什么？生活在贫困地区的年轻人已被确定为衣原体的高危人群。定性研究已确定了与影响衣原体检测接受度的因素相关的几个主题，这些主题与计划行为理论（TPB）的构念非常契合。身份认同问题也被认为在年轻人的衣原体检测决策中起着重要作用。本研究增加了什么？TPB解释了衣原体检测意图中43%的变异，所有变量均为显著预测因素。自我认同解释了意图中额外22%的变异，并且是最强的预测因素。表明了在促进贫困年轻人定期进行衣原体检测的干预措施中应针对的关键变量。
