Self-injurious behaviors (SIBs) and problematic shopping (PS) are both prevalent in adolescents. These behaviors have been proposed as behavioral addictions and linked to impulsivity (Imp) and sensation-seeking (SS). They are also associated with negative mental health and psychosocial measures. This study examined relationships between PS and SIB in adolescents. It also examined how PS and SIB relate to Imp and SS, and interactions between PS and SIB in relation to health/functioning measures.
Survey data from 2,624 Connecticut high-school students were evaluated using chi-square analyses. Next, logistic regression models were used to assess relationships between PS and measures of SIB. T-tests compared Imp and SS in adolescents with and without PS and SIB. Interaction analyses assessed effects of PS on relationships between SIB and health/functioning measures.
Adolescents with PS had 3.43-fold higher odds of endorsing lifetime SIB than those without PS, and were more likely to exhibit severe SIB and disruption due to SIB. PS and SIB were associated with elevated Imp and SS. Interaction analyses revealed that in adolescents with PS, the relationships between SIB and substance use was weaker than in adolescents without PS. This suggests PS accounts for variance in relationships between SIB and substance use.
PS is strongly related to SIB prevalence, severity, and impairment in adolescents, and weakens associations between SIB and substance use. PS should therefore be considered for prevention efforts for SIB. Further research should investigate mechanisms connecting PS and SIB and explore possible interventions targeting associated features like Imp and SS.
自伤行为（SIB）和问题性购物（PS）在青少年中都很普遍。这些行为被认为是行为成瘾，并与冲动性（Imp）和寻求刺激（SS）有关。它们也与负面的心理健康和心理社会措施有关。本研究调查了青少年中 PS 和 SIB 之间的关系。它还研究了 PS 和 SIB 如何与 Imp 和 SS 相关，以及 PS 和 SIB 之间的相互作用与健康/功能测量之间的关系。
使用卡方分析评估了来自康涅狄格州 2624 名高中生的调查数据。然后，使用逻辑回归模型评估了 PS 与 SIB 测量之间的关系。t 检验比较了有和没有 PS 和 SIB 的青少年的 Imp 和 SS。交互分析评估了 PS 对 SIB 与健康/功能测量之间关系的影响。
有 PS 的青少年比没有 PS 的青少年发生终生 SIB 的可能性高 3.43 倍，并且更有可能表现出严重的 SIB 和因 SIB 而中断。PS 和 SIB 与升高的 Imp 和 SS 有关。交互分析显示，在有 PS 的青少年中，SIB 与物质使用之间的关系比没有 PS 的青少年弱。这表明 PS 解释了 SIB 和物质使用之间关系的变异性。
PS 与青少年中 SIB 的流行率、严重程度和损伤密切相关，并削弱了 SIB 和物质使用之间的关联。因此，应考虑将 PS 用于预防 SIB 的努力。进一步的研究应调查连接 PS 和 SIB 的机制，并探索针对 Imp 和 SS 等相关特征的可能干预措施。
