Many of the theories used in behavioral cybersecurity research have been applied with a nomothetic approach, which is characterized by cross-sectional data (e.g., one-time surveys) that identify patterns across a population of individuals. Although this can provide valuable between-person, point-in-time insights (e.g., employees who use neutralization techniques, such as denying responsibility for cybersecurity policy violations, tend to comply less), it is unable to reveal within-person patterns that account for varying experiences and situations over time. This paper articulates why an idiographic approach, which undertakes a within-person analysis of longitudinal data, can: (1) help validate widely used theories in behavioral cybersecurity research that imply patterns of behavior within a given person over time and (2) provide distinct theoretical insights on behavioral cybersecurity phenomena by accounting for such within-person patterns. To these ends, we apply an idiographic approach to an established theory in behavioral cybersecurity research--neutralization theory--and empirically test a within-person variant of this theory using a four-week experience sampling study. Our results support a more granular application of neutralization theory in the cybersecurity context that considers the behavior of a given person over time. We conclude the paper by highlighting the contexts and theories that provide the most promising opportunities for future behavioral cybersecurity research using an idiographic approach.

Background: Clinical data are usually analyzed with the assumption that knowledge gathered from group averages applies to the individual. Doing so potentially obscures patients with meaningfully different trajectories of therapeutic change. Needed are "idionomic" methods that first examine idiographic patterns before nomothetic generalizations are made. The objective of this paper is to test whether such an idionomic method leads to different clinical conclusions. Methods: 51 patients completed weekly process measures and symptom severity over a period of eight weeks. Change trajectories were analyzed using a nomothetic approach and an idiographic approach with bottom-up clustering of similar individuals. The outcome was patients' well-being at post-treatment. Results: Individuals differed in the extent that underlying processes were linked to symptoms. Average trend lines did not represent the intraindividual changes well. The idionomic approach readily identified subgroups of patients that differentially predicted distal outcomes (well-being). Conclusions: Relying exclusively on average results may lead to an oversight of intraindividual pathways. Characterizing data first using idiographic approaches led to more refined conclusions, which is clinically useful, scientifically rigorous, and may help advance individualized psychotherapy approaches.

Windelband ([1894]1980) advocated that two approaches are used for accumulating scientific knowledge. The first is the idiographic approach that derives knowledge from a single unit, and the second is the nomothetic approach that accumulates knowledge of a group. Given these two approaches, the former matches case studies while the latter is more appropriate with experimental group studies. Scientists have criticized both methodologies for their various limitations. Later, the single-case methodology emerged as an alternative that potentially allays these limitations. In this context, this narrative review aims to describe the historical roots of single-case experimental designs (SCEDs) that have emerged to eliminate the tension of nomothetic and idiographic approaches over time. First, the review focuses on the emergence of SCEDs. Second, the strengths and challenges of SCEDs are reviewed, including those to address the limitations of group experimental and case studies. Third, the use and analyses of SCEDs are outlined, considering their current status. Fourth, this narrative review continues to delineate the dissemination of SCEDs in the modern scientific world. As a result, SCEDs can be evaluated as a method that has the potential to overcome the issues encountered in case description and group experimental research. Thus, that helps accumulate nomothetic and idiographic knowledge in determining evidence-based practices. [ABSTRACT FROM AUTHOR]

A complex systems approach to psychopathology proposes that general principles lie in the dynamic patterns of psychopathology, which are not restricted to specific psychological processes like symptoms or affect. Hence, it must be possible to find general change profiles in time series data of fully personalized questionnaires. In the current study, we examined general change profiles in personalized self-ratings and related these to four measures of treatment outcome (International Symptom Rating, 21-item Depression Anxiety and Stress Scale, daily symptom severity, and self-reflective capacity). We analyzed data of 404 patients with mood and/or anxiety disorders who completed daily self-ratings on personalized questionnaires during psychotherapy. For each patient, a principal component analysis was applied to the multivariate time series in order to retrieve an univariate person-specific time series. Then, using classification and regression methods, we examined these time series for the presence of general change profiles. The change profile classification yielded the following distribution of patients: no-shift (n = 55; 14%), gradual-change (n = 52; 13%), one-shift (n = 233; 58%), reversed-shift (n = 39; 10%) and multiple-shifts (n = 25; 6%). The multiple-shift group had better treatment outcome than the no-shift group on all outcome measures. The one-shift and gradual-change groups had better treatment outcome than the no-shift group on two and three outcome measures, respectively. Overall, this study illustrates that person-specific (idiographic) and general (nomothetic) aspects of psychopathology can be integrated in a complex systems approach to psychopathology, which may combine "the best of both worlds." General Scientific Summary: Personalized questionnaires have clinical and intuitive appeal, but the question rises how to generalize if questionnaires measure different constructs in different patients. In this article, we develop a novel method to abstract general change profiles from personalized daily questionnaire data collected during psychotherapy. We find that the way in which patients change on their personalized questionnaire over the course of treatment is related to treatment outcome as predicted by the complexity theory of psychopathology.

The article is a critical analysis of selected issues examined in Wprowadzenie do metodologii historii (Introduction to the Methodology of History), edited by Ewa Domańska and Jan Pomorski, Warsaw 2022. The reviewer focuses on general methodological and epistemological issues, believing that the authors of the various chapters pay too little attention, for the most part, to the relation between the methodology of history and general methodology. The discussion concerns the history of historiography, the role of history in the emergence of the humanities, the dispute over the status of history in the nineteenth century, particularly nomothetism and idiographism in the light of Auguste Comte's classification of sciences compiled in France and their division as seen by Wilhelm Windelband and Heinrich Rickert, proposed in Germany, as well as explanation in historiography. With regard to that last point, deductive-nomological and genetic explanations are considered. Attention is drawn to the problematic nature of the application of the classic pattern of deductive-nomological explanation in connection with the problem of universal laws and historical theories (more generally - concerning the social sciences), as well as to the differences in the understanding of causality in historiography and theoretical natural sciences, which is relevant to the analysis of the genetic explanation. In the final section of the article the author points to the link between the approach to historical cognition and general problems of epistemology. [ABSTRACT FROM AUTHOR]

Background: There have been two kinds of methods for assessing individuals' motivation and their goal‐striving behavior. The idiographic method obtains respondents' individual descriptions of their behavior or inner experiences. The nomothetic approach uses a standardized questionnaire in which respondents select from a set of alternatives. Idiographic responses provide rich, individualized information, but they make comparisons across different individuals difficult. By contrast, the nomothetic approach loses valuable individualized information, but it readily lends itself to cross‐individual comparisons. Objective: The present authors have developed a family of motivational assessment instruments within the framework of the Goal Theory of Current Concerns and individuals' goal pursuits. Each of these instruments is a hybrid version of the idiographic and nomothetic methods. Each one obtains individualized information about each respondent at the start of the assessment, but it then utilizes rating scales that allow comparisons across different individuals to be made. The objective of the present article is to present this family of hybridized instruments for potential use in routine outcome monitoring. Method: The method used in this article was to review the development of this family of hybrid assessments instruments over the preceding decades and the research on their psychometric properties and clinical applications. These hybrid tools include the Interview Questionnaire, Work Concerns Inventory, Motivational Structure Questionnaire, and Personal Concerns Inventory and their variants. The review includes only the idiographic‐nomothetic approaches that are based on the Goal Theory of Current Concerns. Results: The review reveals that for each instrument, motivational indices are calculated, which have been shown to be valid and reliable. Analyses have also revealed adaptive and maladaptive motivational factors. Conclusions: The measures discussed here have proven useful in clinical applications, when, for example, they are used as components of Systematic Motivational Counseling and the Life Enhancement and Advancement Programme for helping individuals improve their motivational structure. Similarly, the measures hold promise for use in routine outcome monitoring. [ABSTRACT FROM AUTHOR]

\n Research in psychology can have various foci, ranging from the psychological dynamics of single individuals to the generalization across individuals, often termed idiographics and nomothetics, respectively. However, terminological ambiguities have limited communication clarity about idiographics and nomothetics. Importantly, whether studies are suitable for idiographic and/or nomothetic inferences is not categorical but rather a matter of degree. Therefore, we propose a list of concrete, better-defined methodological aspects characterizing individual studies. Specifically, we highlight 16 different decisions researchers have to make pertaining to (1) research question, (2) research design, and (3) analyses and interpretation. These decisions are introduced with a focus on personality psychology but apply to psychological research broadly. We discuss the different decisions with an emphasis on their relation to idiographic and nomothetic inferential goals. Rather than providing specific recommendations, we emphasize the importance of aligning the methodology of a given study with the research question and theory. Overall, this overview seeks to help researchers make relevant decisions more intentionally to help them tailor their studies to their inferential goals.Psychological research can be focused on specific individuals (often termed idiographic) or on generalization across individuals (often termed nomothetic). However, various definitions of these terms exist in the literature. Moreover, multiple different aspects of a study affect whether it allows us to understand a specific person and/or whether it allows generalization across people. To characterize individual psychological studies in a more detailed way, we propose a list of 16 decisions researchers have to make. These decisions include aspects of (1) the research question, (2) the research design, and (3) the analyses and interpretation. We discuss how these decisions are related to idiographics and nomothetics. Moreover, we emphasize the importance of a close match between the questions a study seeks to answer and the methodology used in the study. The proposed list of decisions can be used by other researchers to characterize existing studies as well as to plan new studies. [ABSTRACT FROM AUTHOR]

Three overarching principles governing patterns of geographic phenomena have been proposed that have been referred to by some as ‘laws of geography’. The first and the second principles address the spatial proximity and spatial heterogeneity of geographic phenomena. These principles, while powerful, fail to resonate with much geographical inquiry. The more recently proposed third principle concerns geographic similarity. The differences of it from the first two can be perceived in three basic aspects: principle expressed, form of expression and role of geographic examples (samples). The third principle emphasizes the geographic context of geographic variables in the form of geographic configuration, compared to a single spatial dimension that are emphasized in the first two principles. The third principle focuses on the comparative nature in the geographic configuration in terms of similarity, that is, in the form of ‘similar to’, as opposed to the relationships ‘between’ that are key to the first and second principles. The third principle emphasizes the individual representation of geographic examples, as opposed to the global representation of geographic examples. These differences not only distinguish the third principle as an important addition to the other two, but also provide a potentially transformative way to address the rigid requirements on samples in geographic analysis, particularly during this age when the collection and provision of geographic data are crowd-sourced and VGI-based. These differences also point to the potential of the third principle opening up a space of inquiry that would resonate more successfully with place-based approaches in human geography.

The utility of the Comprehensive System Rorschach rests in the proven relationships between its variables/indices, personality functioning, and real-world behaviors. While the reliability and validity of Comprehensive System data (CS; Exner, 2003; also CS-R; Fontan & Andronikof, 2022) is well established (Gacono & Evans, 2008), other supplemental Rorschach scoring systems also add to understanding our patients (Meloy, Acklin, Gacono, Murray, & Peterson, 1997). Previously, we discussed the importance of anchoring all Rorschach data within a nomothetic context (Gacono & Smith, 2021b). In this article, we discuss a strategy for interpreting the individual protocol. [ABSTRACT FROM AUTHOR]

This article situates the current discussion of reproducibility and replicability taking place across the sciences within geographers' enduring discussion of nomothetic and idiographic approaches, best exemplified by the Hartshorne–Schaefer debate. Although the Hartshorne–Schaefer debate retrospectively set the stage for the development of geography from the 1950s to the present, it is surprising that direct discussions of reproducibility and replicability remain mostly absent from the geographic literature. Drawing from recent literature on reproducibility and replicability in the humanities and physical, social, and computational sciences, it is argued that a deeper focus on these issues will have varied impacts on the discipline. Adopting and improving reproducible practices in geographic research reliant on scientific methods will align geographic research with mainstream scientific inquiry. The discipline's ever-growing diversity of theoretical perspectives and problem domains also makes it likely that a significant portion of geographic research, like many other fields in science, might not be affected by the issues and concerns of reproducibility and replicability. Moving forward, geographic research might continue to benefit from a pluralist framework that embraces both the nomothetic and idiographic approaches, particularly in a broader research environment increasingly defined by disciplinary synthesis and convergence.

The Rorschach (RIM) provides information beyond what one gathers from self-report measures. In addition to CS data, psychoanalytic theory has led to several valid and reliable supplemental Rorschach scoring systems. When integrated, CS and supplemental RIM data increases the conceptual understanding of a patient or group, allowing for highly nuanced insights into personality functioning. In order to interpret Rorschach data one must understand that, for the most part 1) Rorschach variables measure traits (dimensions) not diagnosis (categories), that 2) the degree of pathology or health represented by a variable is determined in relationship to comparative group data, such as non-patients, and assessed within the context of the entire protocol or protocols (for group data), and, 3), confirming the presence or absence of a trait within a given sample necessitates a comparison to other relevant groups both those that contain threshold quantities of the identified trait, and those "absence" the trait. Throughout this article we underscore the essential contribution of a nomothetic context (using comparative CS data) for anchoring Rorschach interpretation. [ABSTRACT FROM AUTHOR]

Psychology holds an exceptional position among the sciences. Yet even after 140 years as an independent discipline, psychology is still struggling with its most basic foundations. Its key phenomena, mind and behaviour, are poorly defined (and their definition instead often delegated to neuroscience or philosophy) while specific terms and constructs proliferate. A unified theoretical framework has not been developed and its categorisation as a 'soft science' ascribes to psychology a lower level of scientificity. The article traces these problems to the peculiarities of psychology's study phenomena, their interrelations with and centrality to everyday knowledge and language (which may explain the proliferation and unclarity of terms and concepts), as well as to their complex relations with other study phenomena. It shows that adequate explorations of such diverse kinds of phenomena and their interrelations with the most elusive of all—immediate experience—inherently require a plurality of epistemologies, paradigms, theories, methodologies and methods that complement those developed for the natural sciences. Their systematic integration within just one discipline, made necessary by these phenomena's joint emergence in the single individual as the basic unit of analysis, makes psychology in fact the hardest science of all. But Galtonian nomothetic methodology has turned much of today's psychology into a science of populations rather than individuals, showing that blind adherence to natural-science principles has not advanced but impeded the development of psychology as a science. Finally, the article introduces paradigmatic frameworks that can provide solid foundations for conceptual integration and new developments. [ABSTRACT FROM AUTHOR]

Mixed methods refers to the use of both qualitative and quantitative approaches and methods in one study or sequentially in two or more studies. Without a mixed methods approach there is – to our minds ‐ a risk that only part of a phenomenon or experience is being explored. Our own involvement in mixed methods research has grown out of a shared interest in the concept 'research‐practitioner'. Psychotherapy is a notoriously complex and ever‐developing field, and our growing sense has been that mixed methods research can contribute to a more complete – both broad and deep ‐ sense of knowledge and understanding.

Scientific evidence in the field of psychiatry is mainly derived from group-based (“nomothetic”) studies that yield group-aggregated results, while often the need is to answer questions that apply to individuals. Particularly in the presence of great inter-individual differences and temporal complexities, information at the individual-person level may be valuable for personalized treatment decisions, individual predictions and diagnostics. The single-subject study design can be used to make inferences about individual persons. Yet, the single-subject study is not often used in the field of psychiatry. We believe that this is because of a lack of awareness of its value rather than a lack of usefulness or feasibility. In the present paper, we aimed to resolve some common misconceptions and beliefs about single-subject studies by discussing some commonly heard “facts and fictions.” We also discuss some situations in which the single-subject study is more or less appropriate, and the potential of combining single-subject and group-based study designs into one study. While not intending to plea for single-subject studies at the expense of group-based studies, we hope to increase awareness of the value of single-subject research by informing the reader about several aspects of this design, resolving misunderstanding, and providing references for further reading.

In the critical tradition, environmental education discourse interrogates how knowledge constructs experience. But environmental education also emphasises perceiving, understanding and responding to "more-than-human" beings and processes. These two motivations are in tension. One problem is that the epistemological orientation driving the critique of knowledge seems to render access to something more-than-human a priori impossible. But environmental education squanders its promise and its dream if only ever permitted to talk about the natural world with scarequotes. Our field urgently needs to develop a realism robust against epistemologies that construct impassable barriers between humans and the rest of creation. I propose that this starts with radically reconceiving the nature and relationship between similarity and difference, interpreted in this article as the dynamic between theme and variations. Reworking Windelband's distinction between idiographic and nomothetic research, I suggest that the relationship between theme and variation manifests a fundamental ontological pattern that pervades all things. "Theme and variation" proposes a unifying metaphysical duality in which the more-than-human reveals itself in how things suggest, conform to, modulate, and violate generalisation. Acknowledging and investigating this is part of restoring to other beings and processes their metaphysical, aesthetic, and ethical status, from the skies to the psyche. [ABSTRACT FROM AUTHOR]

Objective: Psychopathology research has relied on discrete diagnoses, which neglects the unique manifestations of each individual's pathology. Borderline personality disorder combines interpersonal, affective, and behavioral regulation impairments making it particularly ill-suited to a "one size fits all" diagnosis. Clinical assessment and case formulation involve understanding and developing a personalized model for each patient's contextualized dynamic processes, and research would benefit from a similar focus on the individual. Method: We use group iterative multiple model estimation, which estimates a model for each individual and identifies general or shared features across individuals, in both a mixed-diagnosis sample (N = 78) and a subsample with a single diagnosis (n = 24). Results: We found that individuals vary widely in their dynamic processes in affective and interpersonal domains both within and across diagnoses. However, there was some evidence that dynamic patterns relate to transdiagnostic baseline measures. We conclude with descriptions of 2 person-specific models as an example of the heterogeneity of dynamic processes. Conclusions: The idiographic models presented here join a growing literature showing that the individuals differ dramatically in the total patterning of these processes, even as key processes are shared across individuals. We argue that these processes are best estimated in the context of person-specific models, and that so doing may advance our understanding of the contextualized dynamic processes that could identify maintenance mechanisms and treatment targets. What is the public health significance of this article?: This study highlights the importance of understanding psychopathology using individualized models. We demonstrate research techniques that can be used to develop personalized models of psychopathology as well as search for commonalities across individuals. [ABSTRACT FROM AUTHOR]

There are significant nomothetic, differential, and idiographic domains of human development. We suggest the usefulness of efforts to understand human development in regard to specific facets of development—for instance, relationships within families with adolescent children—beginning with a focus on the specific, idiographic attributes of individuals. Using these relationships as a sample case, we provide a brief history of the study of the development of these relationships, and we explain the role of models derived from relational developmental systems metatheory in framing contemporary research about this development. We describe some of the nomothetic, differential, and idiographic features of adolescents and families, and we explain the methodological features of a truly developmental approach to measuring the development of mutually influential adolescent↔family relationships. Finally, we discuss the importance of including idiographic‐based information along with nomothetic or differential information in efforts to optimize adolescent–family relationships.

This article examines a sample of comparative-historical literature to assess when convincing generalizations are made and when they are not. Although a variety of factors can affect the potential for generalization, the focus here is on the difference between diachronic and synchronic generalizations. Separate sections are devoted to synchronic-idiographic, synchronic-nomothetic, diachronic-idiographic, and diachronic-nomothetic analysis and research. Evidence is presented to demonstrate that synchronic generalizations are common in comparative history. The most attention in the article is, however, given to the challenges faced when generalizing diachronically and especially when generalizing sequentially. The article ends with a discussion of the effects of inter-societal forces on comparative-historical generalization and with a conclusion outlining when comparative-historical generalizations seem to be more or less successful.

Personality and psychopathology are composed of dynamic and interactive processes among diverse psychological systems, manifesting over time and in response to an individual's natural environment. Ambulatory assessment techniques promise to revolutionize assessment practices by allowing access to the dynamic data necessary to study these processes directly. Assessing manifestations of personality and psychopathology naturalistically in an individual's own ecology allows for dynamic modeling of key behavioral processes. However, advances in dynamic data collection have highlighted the challenges of both fully understanding an individual (via idiographic models) and how s/he compares with others (as seen in nomothetic models). Methods are needed that can simultaneously model idiographic (i.e., person-specific) processes and nomothetic (i.e., general) structure from intensive longitudinal personality assessments. Here we present a method, group iterative multiple model estimation (GIMME) for simultaneously studying general, shared (i.e., in subgroups), and person-specific processes in intensive longitudinal behavioral data. We first provide an introduction to the GIMME method, followed by a demonstration of its use in a sample of individuals diagnosed with personality disorder who completed daily diaries over 100 consecutive days.

This article analyses recent World Bank interventions aimed at improving higher education and local research capacity in low-income countries. Our empirical entry point is a critical analysis of the Development and Innovation Grant (DIG) scheme the Bank rolled out in Cambodia (2010-2015), a virtual carbon copy export of its Academic Initiative Fund in Bangladesh. Offering a rare insider perspective, we argue that the DIG scheme ultimately failed because the Bank so glaringly misunderstood the Cambodian context. We use this case to contemplate the deeper flaws in how the Bank ‘thinks’, highlighting how the world’s most powerful development institution manages to maintain faith in its own infallibility despite failure.

Objective: Dichotomizing clinical trials designs into nomothetic (e.g., randomized clinical trials or RCTs) versus idiographic (e.g., N-of-1 or case studies) precludes use of an array of hybrid designs and potential research questions between these extremes. This paper describes unique clinical evidence that can be garnered using idiographic clinical trials (ICTs) to complement RCT data. Proposed and illustrated herein is that innovative combinations of design features from RCTs and ICTs could provide clinicians with far more comprehensive information for testing treatments, conducting pragmatic trials, and making evidence-based clinical decisions. Method: Mixed model trajectory analysis and unified structural equations modeling were coupled with multiple baseline designs in (a) a true N-of-1 pilot study to improve severe autism-related communication deficits and (b) a small sample preliminary study of two complimentary interventions to relieve wheelchair discomfort. Results: Evidence supported certain mechanisms of treatment outcomes and ruled out others. Effect sizes included mean phase differences (i.e., effectiveness), trajectory slopes, and differences in path coefficients between study phases. Conclusions: ICTs can be analyzed with equivalent rigor as, and generate effect sizes comparable to, RCTs for the purpose of developing hybrid designs to augment RCTs for pilot testing innovative treatment, efficacy research on rare diseases or other small populations, quantifying within-person processes, and conducting clinical trials in many situations when RCTs are not feasible.

The advancement of implementation science is dependent on identifying assessment strategies that can address implementation and clinical outcome variables in ways that are valid, relevant to stakeholders, and scalable. This paper presents a measurement agenda for implementation science that integrates the previously disparate assessment traditions of idiographic and nomothetic approaches. Although idiographic and nomothetic approaches are both used in implementation science, a review of the literature on this topic suggests that their selection can be indiscriminate, driven by convenience, and not explicitly tied to research study design. As a result, they are not typically combined deliberately or effectively. Thoughtful integration may simultaneously enhance both the rigor and relevance of assessments across multiple levels within health service systems. Background on nomothetic and idiographic assessment is provided as well as their potential to support research in implementation science. Drawing from an existing framework, seven structures (of various sequencing and weighting options) and five functions (Convergence, Complementarity, Expansion, Development, Sampling) for integrating conceptually distinct research methods are articulated as they apply to the deliberate, design-driven integration of nomothetic and idiographic assessment approaches. Specific examples and practical guidance are provided to inform research consistent with this framework. Selection and integration of idiographic and nomothetic assessments for implementation science research designs can be improved. The current paper argues for the deliberate application of a clear framework to improve the rigor and relevance of contemporary assessment strategies. [ABSTRACT FROM AUTHOR]
