广泛性焦虑障碍（GAD）在大学生中普遍存在。基于智能手机的干预可能是一种低成本的治疗方法。患有自我报告的GAD的大学生随机接受基于智能手机的指导自助（n = 50）或不接受治疗（n = 50）。治疗后和6个月随访结果包括抑郁焦虑压力量表-简明压力量表（DASS压力）、宾夕法尼亚州立大学焦虑问卷（PSWQ-11）和状态-特质焦虑量表-特质（STAI-T），以及由GAD问卷（第4版）评估的诊断状态。从治疗前到治疗后，接受指导性自助的参与者（与未接受治疗的参与者相比）在DASS压力方面的减少显著更大（d =-0.408），GAD缓解的可能性更大（d =-0.445）。PSWQ-11（d =-0.208）或STAI-T（d =-0.114）的变化无显著组间差异。从术后到6个月随访，DASS压力评分没有显著下降（d =-0.141），在缓解的患者中，78.6%的患者保持缓解。然而，在随访时，不同条件下的缓解参与者比率不再有显著差异（d =-0.229）。基于智能手机的干预措施可能在治疗GAD的某些方面有效。改善症状减轻和长期结果的方法进行了讨论。
Generalized anxiety disorder (GAD) is prevalent among college students. Smartphone-based interventions may be a low-cost treatment method. College students with self-reported GAD were randomized to receive smartphone-based guided self-help (n = 50), or no treatment (n = 50). Post-treatment and six-month follow-up outcomes included the Depression Anxiety Stress Scales-Short Form Stress Subscale (DASS Stress), the Penn State Worry Questionnaire (PSWQ-11), and the State-Trait Anxiety Inventory-Trait (STAI-T), as well as diagnostic status assessed by the GAD-Questionnaire, 4th edition. From pre- to post-treatment, participants who received guided self-help (vs. no treatment) experienced significantly greater reductions on the DASS Stress (d = −0.408) and a greater probability of remission from GAD (d = −0.445). There was no significant between-group difference in change on the PSWQ-11 (d = −0.208) or STAI-T (d = −0.114). From post to six-month follow-up there was no significant loss of gains on DASS Stress scores (d = −0.141) and of those who had remitted, 78.6% remained remitted. Yet rates of remitted participants no longer differed significantly between conditions at follow-up (d = −0.229). Smartphone-based interventions may be efficacious in treating some aspects of GAD. Methods for improving symptom reduction and long-term outcome are discussed.
