It is estimated that individuals with severe health anxiety (HA) utilize 41 %–78 % more healthcare resources than individuals with identified medical diagnoses. Thus, identifying targets for intervention and prevention efforts for HA that are appropriate for primary care or specialty clinic settings is imperative. The aim of the present investigation was to evaluate the effect of a single-session, computerized anxiety sensitivity (AS) intervention on AS and HA. Participants were 68 university students (79.4 % female; Mage = 19.68) with elevated levels of AS and HA. Participants were randomized to either the AS intervention condition or an active control condition and completed self-report and behavioral follow-up assessments at post-intervention, 1-week follow-up, and 1-month follow-up. Results indicated a significant Time x Condition interaction for ASI-3 at each follow-up assessment (all ps < .001), such that individuals in the active condition exhibited greater reductions in AS compared to the control condition. There was no significant Time x Condition interaction for HA at any follow-up. Mediation analyses revealed a significant indirect effect of Condition on changes in HA through changes in AS. No significant effects were observed for behavioral outcomes. Findings suggest that this intervention successfully reduces AS among those who are high in HA and AS and may indirectly contribute to reductions in HA over time through reductions in AS.

一项评估简短的计算机化焦虑敏感性降低干预对健康焦虑的疗效的随机对照试验

据估计,患有严重健康焦虑症 (HA) 的个人使用的医疗保健资源比已确定医疗诊断的个人多 41%–78%。因此,必须确定适合初级保健或专科诊所环境的 HA 干预和预防目标。本调查的目的是评估单次、计算机化的焦虑敏感性 (AS) 干预对 AS 和 HA 的影响。参与者是 68 名大学生(79.4 % 女性;M年龄= 19.68)AS 和 HA 水平升高。参与者被随机分配到 AS 干预条件或主动控制条件,并在干预后、1 周随访和 1 个月随访时完成自我报告和行为随访评估。结果表明在每次后续评估中 ASI-3 的时间 x 条件相互作用显着(所有ps < .001),因此与对照条件相比,处于活动状态的个体表现出更大的 AS 降低。在任何后续行动中,HA 都没有显着的时间 x 条件相互作用。中介分析揭示了 Condition 通过 AS 的变化对 HA 的变化有显着的间接影响。没有观察到对行为结果的显着影响。结果表明,这种干预成功地减少了 HA 和 AS 高的人群中的 AS,并且随着时间的推移可能通过减少 AS 间接促进 HA 的减少。
