We used a daily diary to examine (1) the frequency of three types of NSSI thoughts and urges (fleeting thoughts, persistent thoughts, and intense urges), (2) the correlates of NSSI thought and urges within and across days, (3) strategies that aid in resisting NSSI thoughts and urges, and (4) the prospective association of daily NSSI thoughts and urges with NSSI behavior over 12 months.
Sixty adults (aged 18-35) completed a two-week daily diary and follow-ups every 3 months for one year.
Fleeting NSSI thoughts were reported on 48% of days, whereas persistent thoughts (11%) and intense urges (17%) were less common. Within days, earlier stress predicted more persistent NSSI thoughts, whereas earlier perceived support predicted less intense NSSI urges. Furthermore, NSSI thoughts and urges were positively associated with same-day stress and avoidant coping. Problem-focused coping was associated with greater success resisting same-day fleeting thoughts and intense urges, as well as success resisting next-day persistent thoughts. Perceived support was associated with less intense same-day urges, but also less success resisting these urges. Over the follow-up, persistent thoughts predicted less frequent NSSI, whereas intense urges predicted more frequent NSSI.
NSSI thoughts and urges are commonly experienced and deserve further attention.
我们使用日常日记来考察（1）三种类型的非自杀性自伤（NSSI）想法和冲动（短暂想法、持续想法和强烈冲动）的频率，（2）NSSI 想法和冲动在日内和跨日内的相关性，（3）有助于抵抗 NSSI 想法和冲动的策略，以及（4）日常 NSSI 想法和冲动与 12 个月内 NSSI 行为的前瞻性关联。
60 名年龄在 18-35 岁的成年人完成了为期两周的日常日记，并在接下来的一年中每 3 个月进行一次随访。
48%的日子里出现了短暂的 NSSI 想法，而持续的想法（11%）和强烈的冲动（17%）则较为少见。在日内，早期的压力预测到更多的持续的 NSSI 想法，而早期的感知支持预测到较少的强烈的 NSSI 冲动。此外，NSSI 想法和冲动与当天的压力和回避应对方式呈正相关。问题解决型应对方式与更成功地抵抗当天的短暂想法和强烈冲动以及抵抗次日的持续想法有关。感知支持与当天冲动的强度呈负相关，但也与抵抗这些冲动的成功率呈负相关。在随访期间，持续的想法预测到较少的 NSSI 发生，而强烈的冲动预测到更多的 NSSI 发生。
NSSI 想法和冲动是常见的经历，值得进一步关注。
