  1. A logical-pragmatic perspective on validity.Adriano C. T. Rodrigues & Claudio E. M. Banzato - 2009 - Dialogues in Philosophy, Mental and Neuro Sciences 2 (2):40-44.
    Background: Despite being often taken as the benchmark of quality for diagnostic and classificatory tools, 'validity' is admitted as a poorly worked out notion in psychiatric nosology. Objective: Here we aim at presenting a view that we believe to do better justice to the significance of the notion of validity, as well as at explaining away some misconceptions and inappropriate expectations regarding this attribute in the aforementioned context. Method: The notion of validity is addressed taking into account (...)

  2. A pragmatic meta-conception of validity for diagnostic concepts in psychiatry: a step prior to utility, theories and methods of validation.Adriano C. T. Rodrigues & Claudio E. M. Banzato - 2011 - Dialogues in Philosophy, Mental and Neuro Sciences 4 (1):20-21.
    Dear Editor, in a previous paper we have tried to delve into what validity means in the context of psychiatric nosology, arguing for a pragmatic view of it. Here we want to briefly reassert the basic points of our analysis, make a few clarifications and address some issues raised by commentators.

  3. The DSM-5 introduction of the Social (Pragmatic) Communication Disorder as a new mental disorder: a philosophical review.M. Cristina Amoretti, Elisabetta Lalumera & Davide Serpico - 2021 - History and Philosophy of the Life Sciences 43 (4):1-31.
    The latest edition of the Diagnostic and Statistical Manual of Mental Disorders included the Social Communication Disorder as a new mental disorder characterized by deficits in pragmatic abilities. Although the introduction of SPCD in the psychiatry nosography depended on a variety of reasons—including bridging a nosological gap in the macro-category of Communication Disorders—in the last few years researchers have identified major issues in such revision. For instance, the symptomatology of SPCD is notably close to that of Autism Spectrum Disorder. (...)

  4. Saving the DSM-5? Descriptive conceptions and theoretical concepts of mental disorders.Elisabetta Lalumera - 2016 - Medicina E Storia 9.
    At present, psychiatric disorders are characterized descriptively, as the standard within the scientific community for communication and, to a certain extent, for diagnosis, is the DSM, now at its fifth edition. The main reasons for descriptivism are the aim of achieving reliability of diagnosis and improving communication in a situation of theoretical disagreement, and the Ignorance argument, which starts with acknowledgment of the relative failure of the project of finding biomarkers for most mental disorders. Descriptivism has also the advantage of (...)

  5. The absent body in psychiatric diagnosis, treatment, and research.Catherine Stinson - 2019 - Synthese 196 (6).
    Discussions of psychiatric nosology focus on a few popular examples of disorders, and on the validity of diagnostic criteria. Looking at Anorexia Nervosa, an example rarely mentioned in this literature, reveals a new problem: the DSM has a strict taxonomic structure, which assumes that disorders can only be located on one branch. This taxonomic assumption fails to fit the domain of psychopathology, resulting in obfuscation of cross-category connections. Poor outcomes for treatment of Anorexia may be due to it being (...)

  7. Psychiatric Progress and The Assumption of Diagnostic Discrimination.Kathryn Tabb - 2015 - Philosophy of Science 82:1047-1058.
    The failure of psychiatry to validate its diagnostic constructs is often attributed to the prioritizing of reliability over validity in the structure and content of the Diagnostic and Statistical Manual of Mental Disorders. Here I argue that in fact what has retarded biomedical approaches to psychopathology is unwarranted optimism about diagnostic discrimination: the assumption that our diagnostic tests group patients together in ways that allow for relevant facts about mental disorder to be discovered. I consider the Research Domain Criteria (...)

    Contemporary psychiatry finds itself in the midst of a crisis of classification. The developments begun in the 1980s—with the third edition of the Diagnostic and Statistical Manual of Mental Disorders —successfully increased inter-rater reliability. However, these developments have done little to increase the predictive validity of our categories of disorder. A diagnosis based on DSM categories and criteria often fails to accurately anticipate course of illness or treatment response. In addition, there is little evidence that the DSM categories link (...)

  9. The diagnosis of mental disorders: the problem of reification.Steven Edward Hyman - 2010 - Annual Review of Clinical Psychology 6:155-179.
    A pressing need for interrater reliability in the diagnosis of mental disorders emerged during the mid-twentieth century, prompted in part by the development of diverse new treatments. The Diagnostic and Statistical Manual of Mental Disorders (DSM), third edition answered this need by introducing operationalized diagnostic criteria that were field-tested for interrater reliability. Unfortunately, the focus on reliability came at a time when the scientific understanding of mental disorders was embryonic and could not yield valid disease definitions. Based on accreting problems (...)

    Are psychiatric disorders natural kinds? This question has received a lot of attention within present-day philosophy of psychiatry, where many authors debate the ontology and nature of mental disorders. Similarly, historians of psychiatry, dating back to Foucault, have debated whether psychiatric researchers conceived of mental disorders as natural kinds or not. However, historians of psychiatry have paid little to no attention to the influence of (a) theories within logic, and (b) theories within metaphysics on psychiatric accounts of proper method, and (...)

  11. Valid Arguments as True Conditionals.Andrea Iacona - 2023 - Mind 132 (526):428-451.
    This paper explores an idea of Stoic descent that is largely neglected nowadays, the idea that an argument is valid when the conditional formed by the conjunction of its premises as antecedent and its conclusion as consequent is true. As it will be argued, once some basic features of our naıve understanding of validity are properly spelled out, and a suitable account of conditionals is adopted, the equivalence between valid arguments and true conditionals makes perfect sense. The account of (...)

    Epistemic circularity and measurement validity in quantitative psychology: Insights from Fechner's psychophysics.Michele Luchetti - 2024 - Frontiers in Psychology 15:1354392.
    The validity of psychological measurement is crucially connected to a peculiar form of epistemic circularity. This circularity can be a threat when there are no independent ways to assess whether a certain procedure is actually measuring the intended target of measurement. This paper focuses on how Gustav Theodor Fechner addressed the measurement circularity that emerged in his psychophysical research. First, I show that Fechner's approach to the problem of circular measurement involved a core idealizing assumption of a shared human (...)

  13. Validity as Truth-Conduciveness.Arvid Båve - forthcoming - In Adam Podlaskowski & Drew Johnson (eds.), Truth 20/20. Synthese Library.
    Thomas Hofweber takes the semantic paradoxes to motivate a radical reconceptualization of logical validity, rejecting the idea that an inference rule is valid just in case every instance thereof is necessarily truth-preserving. Rather than this “strict validity”, we should identify validity with “generic validity”, where a rule is generically valid just in case its instances are truth preserving, and where this last sentence is a generic, like “Bears are dangerous”. While sympathetic to Hofweber’s view that strict (...)

  14. Excuse Validation: A Cross‐cultural Study.John Turri - 2019 - Cognitive Science 43 (8):e12748.
    If someone unintentionally breaks the rules, do they break the rules? In the abstract, the answer is obviously “yes.” But, surprisingly, when considering specific examples of unintentional, blameless rule-breaking, approximately half of people judge that no rule was broken. This effect, known as excuse validation, has previously been observed in American adults. Outstanding questions concern what causes excuse validation, and whether it is peculiar to American moral psychology or cross-culturally robust. The present paper studies the phenomenon cross-culturally, focusing on Korean (...)

    Born 80 years ago, Continental Philosophy is on its last legs. Its extraordinary career has been helped along by an almost total absence of interest on the part of analytic or other exact philosophers in what the Australian philosopher David Stove calls "the nosology of philosophy" 1, the exploration of the manifold forms taken by bad philosophy. Stove points out that such an enterprise involves doing history. A nosology of Continental Philosophy is, at least in the first instance, inseparable from (...)

    Beall and Murzi :143–165, 2013) introduce an object-linguistic predicate for naïve validity, governed by intuitive principles that are inconsistent with the classical structural rules. As a consequence, they suggest that revisionary approaches to semantic paradox must be substructural. In response to Beall and Murzi, Field :1–19, 2017) has argued that naïve validity principles do not admit of a coherent reading and that, for this reason, a non-classical solution to the semantic paradoxes need not be substructural. The aim of (...)

    Nontransitive responses to the validity Curry paradox face a dilemma that was recently formulated by Barrio, Rosenblatt and Tajer. It seems that, in the nontransitive logic ST enriched with a validity predicate, either you cannot prove that all derivable metarules preserve validity, or you can prove that instances of Cut that are not admissible in the logic preserve validity. I respond on behalf of the nontransitive approach. The paper argues, first, that we should reject the detachment (...)

I approach this topic by way of an analysis of recent debates about the measurement of implicit social cognition.

I show that there are two questions at (...)

    What is a valid measuring instrument? Recent philosophy has attended to logic of justification of measures, such as construct validation, but not to the question of what it means for an instrument to be a valid measure of a construct. A prominent approach grounds validity in the existence of a causal link between the attribute and its detectable manifestations. Some of its proponents claim that, therefore, validity does not depend on pragmatics and research context. In this paper, I (...)

    Psychiatric research is in crisis because of repeated failures to discover new drugs for mental disorders. Lack of measurement validity could partly account for these failures. If researchers do not actually measure the effects of drugs on the disorders they aim to investigate, one should expect suboptimal treatment outcomes. I argue that this is the case, focusing on depression, and fear & anxiety disorders. In doing so, I show how psychiatric research illustrates a more general phenomenon that I call (...)

    Should Theories of Logical Validity Self-Apply?Marco Grossi - forthcoming - Erkenntnis.
    Some philosophers argue that a theory of logical validity should not interpret its own language, because a Russellian argument shows that self-applicability is inconsistent with the ability to capture all the interpretations of its own language. First, I set up a formal system to examine the Russellian argument. I then defend the need for self-applicability. I argue that self-applicability seems to be implied by generality, and that the Russellian argument rests on a test for meaning that is biased against (...)

    In this paper we describe a few interrelated issues for validating theories that posit levels of consciousness. First, validating levels of consciousness requires consensus about the ordering of conscious states, which cannot be easily achieved. This problem is particularly severe if we believe conscious states can be irreducibly smeared over time. Second, the relationship between conscious states is probably sometimes intransitive, which means levels of consciousness will not be amenable to a single continuous measure. Finally, even if a multidimensional approach (...)

  23. Excuse validation: a study in rule-breaking.John Turri & Peter Blouw - 2015 - Philosophical Studies 172 (3):615-634.
    Can judging that an agent blamelessly broke a rule lead us to claim, paradoxically, that no rule was broken at all? Surprisingly, it can. Across seven experiments, we document and explain the phenomenon of excuse validation. We found when an agent blamelessly breaks a rule, it significantly distorts people’s description of the agent’s conduct. Roughly half of people deny that a rule was broken. The results suggest that people engage in excuse validation in order to avoid indirectly blaming others for (...)

  24. Validity as (material!) truth‐preservation in virtue of form.Tristan Grøtvedt Haze - 2022 - Analytic Philosophy 64 (2):177-181.
    According to a standard story, part of what we have in mind when we say that an argument is valid is that it is necessarily truth preserving: if the premises are true, the conclusion must also be true. But—the story continues—that’s not enough, since ‘Roses are red, therefore roses are coloured’ for example, while it may be necessarily truth-preserving, is not so in virtue of form. Thus we arrive at a standard contemporary characterisation of validity: an argument is valid (...)

    While Thomas Kuhn's theory of scientific revolutions does not specifically deal with validation, the validation of simulations can be related in various ways to Kuhn's theory: 1) Computer simulations are sometimes depicted as located between experiments and theoretical reasoning, thus potentially blurring the line between theory and empirical research. Does this require a new kind of research logic that is different from the classical paradigm which clearly distinguishes between theory and empirical observation? I argue that this is not the case.

    What are people who disagree about logic disagreeing about? The paper argues that (in a wide range of cases) they are primarily disagreeing about how to regulate their degrees of belief. An analogy is drawn between beliefs about validity and beliefs about chance: both sorts of belief serve primarily to regulate degrees of belief about other matters, but in both cases the concepts have a kind of objectivity nonetheless.

    An inference is valid if it guarantees the transferability of knowledge from the premisses to the conclusion. If knowledge is here understood as demonstrative knowledge, and demonstration is explained as a chain of valid inferences, we are caught in an explanatory circle. In recent lectures, Per Martin-Löf has sought to avoid the circle by specifying the notion of knowledge appealed to in the explanation of the validity of inference as knowledge of a kind weaker than demonstrative knowledge. The resulting (...)

This paper concerns an apparently analogous paradox, about validity rather than truth, which JC Beall and Julien Murzi call the v-Curry.

    For semantic inferentialists, the basic semantic concept is validity. An inferentialist theory of meaning should offer an account of the meaning of "valid." If one tries to add a validity predicate to one's object language, however, one runs into problems like the v-Curry paradox. In previous work, I presented a validity predicate for a non-transitive logic that can adequately capture its own meta-inferences. Unfortunately, in that system, one cannot show of any inference that it is invalid. Here (...)

  37. Why Is a Valid Inference a Good Inference?Sinan Dogramaci - 2015 - Philosophy and Phenomenological Research 94 (1):61-96.
    True beliefs and truth-preserving inferences are, in some sense, good beliefs and good inferences. When an inference is valid though, it is not merely truth-preserving, but truth-preserving in all cases. This motivates my question: I consider a Modus Ponens inference, and I ask what its validity in particular contributes to the explanation of why the inference is, in any sense, a good inference. I consider the question under three different definitions of ‘case’, and hence of ‘validity’: the orthodox (...)

    Hardcore actualism (HA) grounds all modal truths in the concrete constituents of the actual world (see, e.g., Borghini and Williams (2008), Jacobs (2010), Vetter (2015)). I bolster HA, and elucidate the very nature of possibility (and necessity) according to HA, by considering if it can validate S5 modal logic. Interestingly, different considerations pull in different directions on this issue. To resolve the tension, we are forced to think hard about the nature of the hardcore actualist's modal reality and how radically (...)

If our knowledge of validity must be based on some reasoning, then we seem to be committed to the legitimacy of rule-circular arguments for validity. This paper raises a new difficulty for the rule-circular account of our knowledge of validity. The source of the problem is that, contrary to traditional wisdom, a universal generalization cannot be inferred just on (...)

Validation of an instrument and measurement of employee work-life policies, psychological Empowerment, and job commitment of academic staff in universities.Valentine Joseph Owan, Bassey Asuquo Bassey, Usen Friday Mbon, Abigail Edem Okon, Ene Ogar Egbula, Samuel Okpon Ekaette, Cyprian Oba Ojong & Mercy Bassey Ekpe - 2020 - Mediterranean Journal of Social Sciences 11 (2):86-100.
    This study used a structural equation modelling approach to assess the association between employee work- life policies, psychological empowerment, and academic staff job commitment in universities in Cross River State, Nigeria. Three null hypotheses were formulated to guide the study following a descriptive survey research design. Multistage sampling procedure was adopted in the selection of 315 academic staff from two universities in the study area. “Work-Life Policies, Psychological Empowerment and Job Commitment Questionnaire (WPPEJCQ)” was used as the instrument for data (...)

  45. The Validity of Aquinas’ Third Way.Rem B. Edwards - 1971 - New Scholasticism 45 (1):117-126.
    This article argues for the formal validity of and the truth of the premises and conclusion of a version of Aquinas' "Third Way" that says: If each of the parts of nature is contingent, the whole of nature is contingent. Each of the parts of nature is contingent. Therefore, the whole of nature is contingent--where "contingent" means having a cause and not existing self-sufficiently.

  46. Validity and actuality.Vittorio Morato - 2014 - Logique Et Analyse 227:379-405.
    The notion of validity for modal languages could be defined in two slightly different ways. The first is the original definition given by S. Kripke, for which a formula φ of a modal language L is valid if and only if it is true in every actual world of every interpretation of L. The second is the definition that has become standard in most textbook presentations of modal logic, for which a formula φ of L is valid if and (...)

  47. Validation and Verification in Social Simulation: Patterns and Clarification of Terminology.Nuno David - 2009 - Epistemological Aspects of Computer Simulation in the Social Sciences, EPOS 2006, Revised Selected and Invited Papers, Lecture Notes in Artificial Intelligence, Squazzoni, Flaminio (Ed.) 5466:117-129.
    The terms ‘verification’ and ‘validation’ are widely used in science, both in the natural and the social sciences. They are extensively used in simulation, often associated with the need to evaluate models in different stages of the simulation development process. Frequently, terminological ambiguities arise when researchers conflate, along the simulation development process, the technical meanings of both terms with other meanings found in the philosophy of science and the social sciences. This article considers the problem of verification and validation in (...)

  48. Validity study using factor analyses on the Defining Issues Test-2 in undergraduate populations.Youn-Jeng Choi, Hyemin Han, Meghan Bankhead & Stephen J. Thoma - 2020 - PLoS ONE 15 (8):e0238110.
    Introduction The Defining Issues Test (DIT) aimed to measure one’s moral judgment development in terms of moral reasoning. The Neo-Kohlbergian approach, which is an elaboration of Kohlbergian theory, focuses on the continuous development of postconventional moral reasoning, which constitutes the theoretical basis of the DIT. However, very few studies have directly tested the internal structure of the DIT, which would indicate its construct validity. Objectives Using the DIT-2, a later revision of the DIT, we examined whether a bi-factor model (...)

  49. Validity and Soundness in the First Way.Graham Oppy - 2023 - Revista Portuguesa de Filosofia 79 (1-2):137-158.
    This article critically examines the structure and implications of the argument in ST 1, Q2, A3, associated with Aquinas’ First Way. Our central endeavor is to discern whether a certain disambiguation of point 6 (“There is something that is not moving/changing that moves/changes other things”) can be logically inferred from points 1-5. Through a three-part proof, the article establishes that under specific conditions, it can indeed be inferred. However, this interpretation notably diverges from Aquinas’ intended conclusion and subsequent stronger interpretations (...)

  50. Modal validity and the dispensability of the actuality operator.Vittorio Morato - 2014 - In Michal Dancak & Vit Puncochar (eds.), The Logica Yearbook 2013.
    In this paper, I claim that two ways of defining validity for modal languages (“real-world” and “general” validity), corresponding to distinction between a correct and an incorrect way of defining modal valid- ity, correspond instead to two substantive ways of conceiving modal truth. At the same time, I claim that the major logical manifestation of the real- world/general validity distinction in modal propositional languages with the actuality operator should not be taken seriously, but simply as a by-product (...)
