Youth account for almost half of all new HIV infections in the United States. Adherence to antiretroviral treatment (ART) is critical for successful management, yet reported adherence rates for youth are often low. This study pilot-tested "+CLICK," an innovative, web-based, adherence intervention for HIV-positive youth as an adjunct to traditional clinic-based, self-management education. The theory-based application, developed for HIV-infected youth, 13-24 years of age, provides tailored activities addressing attitudes, knowledge, skills, and self-efficacy related to ART adherence. HIV-positive youth (N=10) pilot-tested "+CLICK" to assess usability (ease of use, credibility, understandability, acceptability, motivation) and short-term psychosocial outcomes (importance and self-efficacy related to ART adherence) using a single-group, pre-/post-test study design in a hospital-based pediatric clinic (n=8) and home (n=2) location. Youth were mostly female (80%) and Black (80%). Mean age was 17.8 years (SD=2.65, range 14-22). All were infected perinatally and had been living with HIV all their lives. Most learned their HIV status by age 10 years. Sixty percent reported an undetectable viral load, whilst 10% reported a viral load of over 50,000. Half (50%) reported a normal CD4 count, whilst 20% reported having low CD4 (<200). Usability ratings indicated "+CLICK" was very easy to use (70%), trustworthy, and understandable (both>90%). Most (70%) indicated they would use "+CLICK" again. Short-term psychosocial outcomes indicate significant increase in medication adherence self-efficacy (p<0.05), perceived importance of taking antiretroviral medicine close to the right time every day (p<0.05), and knowledge about HIV and adherence (p<0.01). Other psychosocial variables and behavioral intentions were not significantly impacted. Results suggest that "+CLICK" has the potential to affect psychological antecedents to ART adherence. Further research on long-term and behavioral effects is indicated prior to broader dissemination into clinical practice.
在美国,新增艾滋病病毒(HIV)感染者中近一半为年轻人。坚持抗逆转录病毒治疗(ART)对于成功治疗至关重要,但据报告,年轻人的治疗依从率往往较低。本研究对“+CLICK”进行了试点测试,这是一种创新的、基于网络的干预措施,用于帮助HIV阳性青年坚持治疗,作为传统的基于诊所的自我管理教育的辅助手段。该基于理论的应用程序是为13至24岁的HIV感染青年开发的,提供了针对与ART依从性相关的态度、知识、技能和自我效能的定制活动。HIV阳性青年(N = 10)对“+CLICK”进行了试点测试,在一家医院的儿科诊所(n = 8)和家中(n = 2)地点,采用单组前后测试研究设计,评估其可用性(易用性、可信度、可理解性、可接受性、动机)和短期心理社会结果(与ART依从性相关的重要性和自我效能)。这些青年大多为女性(80%),黑人(80%)。平均年龄为17.8岁(标准差 = 2.65,范围14 - 22岁)。所有人均在出生时感染HIV,且一生都感染着HIV。大多数人在10岁时得知自己的HIV感染状况。60%的人报告病毒载量不可检测,而10%的人报告病毒载量超过50,000。一半(50%)的人报告CD4计数正常,而20%的人报告CD4水平低(<200)。可用性评级表明,“+CLICK”非常易于使用(70%)、值得信赖且易于理解(两者均>90%)。大多数人(70%)表示他们会再次使用“+CLICK”。短期心理社会结果表明,药物依从性自我效能显著提高(p<0.05),每天在接近正确时间服用抗逆转录病毒药物的感知重要性显著提高(p<0.05),以及关于HIV和依从性的知识显著增加(p<0.01)。其他心理社会变量和行为意图未受到显著影响。结果表明,“+CLICK”有可能影响ART依从性的心理前提因素。在更广泛地推广到临床实践之前,需要对长期和行为影响进行进一步研究。
