The I-PACE (Interaction of Person-Affect-Cognition-Execution) model provides a theoretical framework for specific Internet use disorders (IUDs) by addressing core mechanisms and possible interaction effects, and integrates several theories, concepts, and empirical findings from addiction research. The I-PACE model is an important theoretical background and constitutes the overall framework of the Research Unit. The model focuses on the interactions between predisposing variables, and affective and cognitive responses resulting in the decision to use a certain application. The empirical findings on particular variables have been integrated in the I-PACE model, and very recent studies seem to confirm specific hypotheses that are expressed in the theoretical framework. The majority of previous studies, however, were limited to the investigation of a very specific aspect related to a particular type of IUD, without considering systematic interactions (moderating and mediating effects) among a comprehensive set of variables and among different types of IUD. This project aims to test the overall model assumptions of the Research Unit, which are based on the I-PACE model. Using data from a core battery of tests and questionnaires assessed in RP2-RP8, including individuals with specific types of IUD, the overall hypotheses of the Research Unit on the role of predictors, moderators, and mediators in explaining symptom severity of specific IUDs will be tested. Using mean structure analyses, commonalities and differences across specific types of IUD will be investigated. The potential shift from early to later stages (i.e. risky to pathological use) and the respective underlying mechanisms (e.g., stronger cue reactivity and additional involvement of reduced stimuli-specific inhibitory control in later stages) will be addressed in a systematic cross-sectional study including individuals with risky compared to pathological use of the applications relating to four proposed types of IUD. Results on specific situational triggers and individual experiences in everyday life will be validated using ambulatory assessment and compared across diverse types of IUD. Finally, longitudinal studies are very rare in this research field and we therefore aim to look at an at least six-month follow-up after the laboratory investigation that will investigate the relationships between specific affective and cognitive components and the development of symptoms in the subsequent months. RP1 may be considered as a central scientific project within the Research Unit, as it will integrate all data from the core battery from RP2-RP8 to test the overall research hypotheses. The link between RP1 and all other RPs is bidirectional: RP2-RP8 will provide the raw data for the overall analyses in RP1 and receive information on all assessed variables for use in the analyses of their specific project.

I-PACE(Interaction of Person-Effect-Cognition-Execution)模型通过研究网络使用障碍的核心机制和可能的交互作用效应，为特定网络使用障碍(IUD)提供了一个理论框架，并整合了成瘾研究中的几个理论、概念和实证结果。I-Pace模式是一个重要的理论背景，构成了研究股的总体框架。该模型侧重于易感变量与情感和认知反应之间的相互作用，从而决定使用某一应用程序。关于特定变量的经验发现已被整合到i-Pace模型中，最近的研究似乎证实了理论框架中表达的特定假设。然而，以前的大多数研究仅限于调查与特定类型的宫内节育器有关的一个非常具体的方面，而没有考虑一组综合变量之间和不同类型的宫内节育器之间的系统性相互作用(调节和中介效应)。该项目旨在测试研究股的总体模型假设，这些假设是基于i-Pace模型的。使用RP2-RP8中评估的一组核心测试和问卷的数据，包括患有特定类型宫内节育器的个人，将检验研究单位关于预测者、调节者和介体在解释特定宫内节育器症状严重程度方面的作用的总体假设。使用平均结构分析，将调查不同类型宫内节育器的共性和差异。从早期到后期的潜在转移(即病理使用的风险)和各自的潜在机制(例如，更强的线索反应性和后期减少的刺激特异性抑制控制的额外参与)将在一项系统的横断面研究中讨论，该研究包括与病理使用相关的四种类型的IUD相关的风险个人。日常生活中特定情景触发因素和个人经历的结果将通过动态评估得到验证，并在不同类型的IUD中进行比较。最后，纵向研究在这一研究领域非常罕见，因此我们的目标是在实验室调查之后进行至少六个月的随访，调查特定情感和认知成分与随后几个月症状发展之间的关系。RP1可被视为研究股内的一个中心科学项目，因为它将整合来自RP2-RP8核心电池的所有数据，以检验整个研究假设。方案1与所有其他方案之间的联系是双向的：方案2-方案8将为方案方案1的全面分析提供原始数据，并收到所有评估变量的信息，以用于其具体项目的分析。
