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-Affect-Cognition-Execution）模型通过解决核心机制和可能的相互作用效应为特定的互联网使用障碍（IUD）提供了一个理论框架，并整合了成瘾研究的几个理论，概念和实证结果。I-PACE模型是一个重要的理论背景，构成了研究股的总体框架。该模型的重点是诱发变量之间的相互作用，以及情感和认知反应导致的决定使用某种应用程序。关于特定变量的实证研究结果已纳入I-PACE模型，最近的研究似乎证实了理论框架中表达的具体假设。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相关的非常具体的方面，而没有考虑一组全面的变量之间和不同类型的宫内节育器之间的系统相互作用（调节和介导效应）。该项目旨在测试研究股基于I-PACE模型的总体模型假设。使用RP 2-RP 8中评估的核心测试和问卷的数据，包括具有特定类型IUD的个体，将测试研究单位关于预测因子、调节因子和介导因子在解释特定IUD症状严重程度方面的作用的总体假设。使用平均结构分析，共同点和不同的特定类型的宫内节育器将进行调查。从早期到晚期的潜在转变（即对病理性使用的风险）和各自的潜在机制（例如，更强的线索反应性和在后期阶段减少的刺激特异性抑制控制的额外参与）将在一项系统性横断面研究中得到解决，该研究包括与四种拟议类型的IUD相关的应用的病理使用相比具有风险的个体。具体的情景触发和个人的日常生活经验的结果将使用门诊评估进行验证，并在不同类型的宫内节育器比较。最后，纵向研究在这个研究领域是非常罕见的，因此，我们的目标是在实验室调查后进行至少6个月的随访，调查特定的情感和认知成分与随后几个月症状发展之间的关系。RP 1可以被视为研究单位内的一个中心科学项目，因为它将整合RP 2-RP 8核心电池的所有数据，以测试整体研究假设。RP 1和所有其他RP之间的联系是双向的：RP 2-RP 8将为RP 1中的总体分析提供原始数据，并接收有关所有评估变量的信息，以用于其特定项目的分析。
