Memory Specificity Training (MeST), a group training protocol, is effective in improving autobiographical memory specificity (AMS), and in so doing, reducing emotional disorder symptoms amongst clinical groups. We examined MeST's effectiveness when the core component (memory specificity trials) is offered online and individually (c-MeST).
A multiple-baseline across-participants design with a randomization-to-baseline length (14 to 33 days) was used. Participants were twenty adults (16 female; = 50, = 12) experiencing reduced AMS, at least one lifetime depressive episode and who currently reported at least minimal depressive symptoms. During baseline, the training phase (nine sessions across 17 days) and a three-month follow-up assessment, AMS, depressive symptoms and related processes were measured.
AMS improved significantly by three months follow-up. Session-to-session scores indicated that AMS improved most from baseline to the first online session, with no further improvement thereafter. In contrast to studies with clinical participants, no significant change in symptoms or secondary processes such as rumination was found.
Translating MeST into an online, individual version is a feasible, low-cost intervention for reduced AMS. Future research should examine c-MeST's potential for preventing increases in symptoms in at-risk samples with longer follow-ups as well as its potential for reducing symptoms in clinical groups.
记忆特异性训练（MeST）是一种团体训练方案，在改善自传体记忆特异性（AMS）方面有效，并且通过这样做，减少临床群体中的情绪障碍症状。我们研究了在核心组成部分（记忆特异性试验）以在线和个体方式提供时（c-MeST）MeST的有效性。
采用了一种跨参与者的多基线设计，随机分配基线长度（14至33天）。参与者为20名成年人（16名女性；年龄范围=50岁，标准差=12），他们的AMS降低，至少有一次终生抑郁发作，且目前至少报告有轻微的抑郁症状。在基线期、训练阶段（17天内进行9次训练）和三个月的随访评估期间，测量了AMS、抑郁症状及相关过程。
到三个月随访时，AMS有显著改善。逐次训练得分表明，AMS从基线到第一次在线训练改善最大，此后没有进一步改善。与针对临床参与者的研究不同，未发现症状或诸如沉思等继发过程有显著变化。
将MeST转化为在线个体版本是一种可行的、低成本的干预措施，可降低AMS。未来的研究应考察c-MeST在更长随访期内预防高危样本中症状增加的潜力，以及其在临床群体中减轻症状的潜力。
