Introduction to the special section on the concept of disorder.

Despite the absence of a consensual definition of disorder, considerable research and clinical work is based on the categorization and diagnosis of mental disorder. This article introduces a special section of the Journal of Abnormal Psychology that expands the debate between J. C. Wakefield (1999), who has proposed a "harmful dysfunction" analysis of disorder and S. O. Lilienfeld and L. Marino (1995, 1999), who offer an alternative "Roschian" or prototype analysis. This introduction summarizes the main arguments of Wakefield's target article and 8 critiques and discusses the conceptual value of the debate, especially an integration of diverse viewpoints and stimulation to further consideration of this important topic.     

Essentialism revisited: evolutionary theory and the concept of mental disorder.

J. C. Wakefield's (1999) elaboration of his harmful dysfunction analysis (HDA) of mental disorder does little to address previous criticisms (S. O. Lilienfeld & L. Marino, 1995) and instead reveals further conceptual weaknesses in his position. The authors demonstrate that (a) a Roschian analysis can account for the results of all of Wakefield's conceptual experiments and predicts a number of judgments of disorder not predicted by the HDA, (b) the HDA is incapable in many cases of providing a scientifically nonarbitrary distinction between disorder and nondisorder, and (c) the HDA cannot account for failures of cultural ex adaptations, mismatches between evolutionary design and novel environments, or defenses against threat. The authors argue that the HDA has been convincingly falsified and discuss the failure of essentialistic concepts to resolve controversies in other domains of biological science.     

Nine variations and a coda on the theme of an evolutionary definition of dysfunction.

Nine variations on the theme of J. C. Wakefield's (1999) evolutionary definition of dysfunction show that the concept is not, as he claims, purely causal. It depends also on a teleological element of meaning introduced, in Wakefield's formulation, through an equivocation on the sense in which natural selection explains biological forms. The corollary (presented here briefly as a coda to the theme and variations) is that Wakefield's definition is not, as he also claims, value free. However, contra S. O. Lilienfeld and L. Marino (1995), this does not place diagnostic judgments of dysfunction outside the scope of science.     

Horsefeathers: a commentary on "evolutionary versus prototype analyses of the concept of disorder".

J. C. Wakefield's (1999) article further develops his harmful dysfunction (HD) model for disorder concepts. This commentary focuses on three areas. The first notes the imbalance in the debate between the Lilienfeld and Marino (1995) Roschian model and the HD model for disorder concepts. The second claims that Wakefield's purposes for the HD model have changed over the years and progressed toward irrelevance to psychopathology in general and toward irrelevance to actual nosologic, reimbursement, and sociopolitical controversies about disorder status. Further discussion is on how certain structural elements in Wakefield's arguments and current limitations of evolutionary theory permit a superficially attractive model for psychopathology. These arguments and limitations, however, harbor serious problems when confronted with actual disputes about disorders. The conclusion notes some virtues to Wakefield's inquiry, in style and substance.     

Evolutionary versus prototype analyses of the concept of disorder.

The harmful dysfunction (HD) analysis of the concept of disorder (J. C. Wakefield, 1992a) holds that disorders are harmful failures of internal mechanisms to perform their naturally selected functions. S. O. Lilienfeld and L. Marino (1995) proposed instead that disorder is a Roschian prototype concept without defining properties. Against the HD analysis, they argued that many disorders are not failures of naturally selected functions because they are either designed reactions (e.g., fever) or failures of functions that are not naturally selected (e.g., reading disorder). The HD analysis is defended here against these and other objections and compared with the Roschian account. It is argued that the objections are based on conceptual confusions and can be turned around to provide strong new support for the HD analysis. A series of conceptual experiments demonstrates the superior explanatory power of the HD analysis and disconfirms the Roschian account.     

The abduction of disorder in psychiatry.

The evolutionary cornerstone of J. C. Wakefield's (1999) harmful dysfunction thesis is a faulty assumption of comparability between mental and biological processes that overlooks the unique plasticity and openness of the brain's functioning design. This omission leads Wakefield to an idealized concept of natural mental functions, illusory interpretations of mental disorders as harmful dysfunctions, and exaggerated claims for the validity of his explanatory and stipulative proposals. The authors argue that there are numerous ways in which evolutionarily intact mental and psychological processes, combined with striking discontinuities within and between evolutionary and contemporary social/cultural environments, may cause nondysfunction variants of many widely accepted major mental disorders. These examples undermine many of Wakefield's arguments for adopting a harmful dysfunction concept of mental disorder.     

Evolutionary history versus current causal role in the definition of disorder: reply to McNally

The harmful dysfunction (HD) analysis (Wakefield, American Psychologist 47 (1992a) 373) asserts that "disorder" means "harmful dysfunction", where "harm" is a value concept anchored in social values and "dysfunction" is a factual concept referring to failure of a mechanism to perform a natural function. Additionally, the HD analysis claims that a mechanism's natural functions are its naturally selected effects. McNally (Behaviour Research and Therapy (2000) pp. 309-314) argues to the contrary that "dysfunction" is a value concept referring to negative failures of function, that "function" refers to current causal roles and not evolutionarily designed causal roles, and that "disorder" consequently means "harmful failure of a mechanism to perform a valued current causal role." I reply by showing that McNally's proposals lack the HD analysis's power to explain common judgments about function, dysfunction, and disorder. "Dysfunction" cannot be a negative value concept because many dysfunctions are positive or neutral; "function" cannot refer to current causal roles because many current causal roles are not functions and some functions are not current causal roles; and "disorder" cannot refer to harmful failures of current causal roles because that definition allows almost any negative condition whatever to be a disorder and thus fails to explain the distinctions we make between disorder and non-disorder.     

Factor structure of the Psychopathic Personality Inventory (PPI): findings from a large incarcerated sample

Exploratory factor analysis (EFA) of the Psychopathic Personality Inventory (PPI; S. O. Lilienfeld, 1990; S. O. Lilienfeld & B. P. Andrews, 1996) with a community sample has suggested that the PPI subscales may comprise 2 higher order factors (S. D. Benning, C. J. Patrick, B. M. Hicks, D. M. Blonigen, & R. F. Krueger, 2003). However, substantive and structural evidence raises concerns about the viability of this 2-factor model, particularly in offender populations. The authors attempted to replicate the S. D. Benning et al. 2-factor solution using a large (N = 1,224) incarcerated male sample. Confirmatory factor analysis of this model resulted in poor model fit. Similarly, using the same EFA procedures as did S. D. Benning et al., the authors found little evidence for a 2-factor model. When they followed the recommendations of J.-W. van Prooijen and W. A. van der Kloot (2001) for recovering EFA solutions, model fit results provided some evidence that a 3-factor EFA solution could be recovered via confirmatory factor analysis.     

Toward an evolutionary taxonomy of treatable conditions.

The definition of disorder as a harmful dysfunction (J. C. Wakefield, 1999) is a useful concept, anchored in the recognition that the evolved human architecture consists of a collection of functional mechanisms that may potentially be impaired and whose impairment may be harmful. Because natural selection organized each mechanism to solve a distinct adaptive problem under ancestral conditions, the criteria for whether a mechanism is dysfunctional are supplied by whether the mechanism has become impaired in performing its ancestral function. Because evolutionary function and dysfunction diverge markedly from normal human standards of value, many dysfunctions are beneficial, whereas various mechanisms that are performing their evolved function may cause disturbing outcomes. For this reason, many conditions in addition to disorders may require treatment, and the authors attempt to sketch an evolutionary taxonomy of treatable conditions.     

Bridging the personal and the political: practices for a liberation psychology

In the Irish context, legacies of colonialism, the Northern Ireland conflict situation, and the strength of community and women's liberation movements all provide rich resources for understanding the processes involved in both oppression and liberation. This paper draws on the theoretical and research literature and on Irish experiences to develop an understanding of some of the processes and practices that aid in liberation. The research is grounded in diverse writings on oppression and liberation, which include writings on colonialism (E. Duran &B. Duran, 1995; F. Fanon, 1967; V. Kenny, 1985, L. Maracle, 1996), feminist psychology (J. B. Miller, 1986; S. Wilkinson, 1996), liberation psychology (H. A. Bulhan, 1985; L. Comas-Díaz, M. B. Lykes, & R. D. Alarcon, 1998; I. Martín-Baró, 1994; Starhawk, 1987), and psychological aspects of racism (b. hooks, 1993; A. Mama, 1995; R. J. Watts, D. M. Griffith, & J. Abdul-Adil, 1999), homophobia (A. R. D'Augelli & C. J. Patterson, 1995), poverty (K. O'Neill, 1992), and other dimensions of oppression.

Mental disorder as a black box essentialist concept.

This is a reply to commentaries on the target article (J. C. Wakefield, 1999) on the evolutionary foundations of the concept of mental disorder in defense of the harmful dysfunction analysis (HDA) of disorder. The author argues that the HDA is adequate to explain disorder and nondisorder judgments and is not disconfirmed by any of the claimed counterexamples put forward by the commentators; the commentators' proposed alternatives to the HDA are inadequate to explain disorder and nondisorder judgments; and the concept of natural function is a factual, scientific concept, contrary to K. W. M. Fulford's (1999) claim that it is inherently evaluative. The foundations of the HDA are clarified by providing a black box essentialist analysis (H. Putnam, 1975; J. C. Wakefield, 1997, in press) of the concept of natural function that underlies the concept of disorder.     

Harmful dysfunction and the search for value neutrality in the definition of mental disorder: response to Wakefield, part 2

Wakefield's claims to have identified and objective scientific component of mental disorders in the concept of dysfunction are examined in light of previous attempts to state a value free concept of mental disorders. The harmful dysfunction concept of dysfunction is not value free because it confounds cause and purpose in a specious use of evolutionary theory and because evolutionary theory cannot reliably supply standards for when a function is broken. Harmful dysfunction analysis collapses into a value-laden concept of mental disorders and serves the untoward goal of promoting the status quo in the modern DSMs. If the concept of dysfunction were taken seriously and rigorously defined, then it might be possible to separate what is medical from what is not in the domain of mental disorders.     

Five-factor model (Big Five) personality traits and universal-diverse orientation in counselor trainees

In this study the authors explored the relationship between five-factor model (FFM: Big Five) personality traits (J. M. Digman, 1990; R. R. McCrae & O. P. John, 1992; J. S. Wiggins & P. D. Trappnell, 1997) and universal-diverse orientation (UDO; M. L. Miville et al., 1999) in counselor trainees. FFM traits were measured using the NEO-Personality Inventory-Revised (P. T. Costa & R. R. McCrae, 1992). Statistically significant relationships were found between UDO and one of the Big Five personality traits (Openness to Experience) in counselor trainees. Further regression analysis suggested a relationship between UDO and a particular facet of Openness to Experience, Openness to Aesthetics. This finding suggests that counselor trainees who are open to the creative expressions of others may be comfortable working with a wide variety of clients. These results suggest that counselor training that encourages experiences of aesthetic diversity in addition to an exploration of values may promote trainees' ability to work with diverse clients.     

The secure-base hypothesis: Global attachment, attachment to counselor, and session exploration in psychotherapy

This study explored J. Bowlby's (1988) secure-base hypothesis, which predicts that a client's secure attachment to the therapist, as well as the client's and the therapist's global attachment security, will facilitate in-session exploration. Volunteer clients (N = 59) and trainee counselors (N = 59) in short-term therapy completed the Experiences in Close Relationship Scale (K. A. Brennan, C. L. Clark, & P. R. Shaver, 1998) as a measure of adult global romantic and peer attachment orientations; the Client Attachment to Therapist Scale (B. Mallinckrodt, D. L. Gantt, & H. M. Coble, 1995) as a measure of attachment to counselor; the Working Alliance Inventory (A. O. Horvath & L. Greenberg, 1989) as a measure of working alliance; and the Session Evaluation Questionnaire-Depth Subscale (W. B. Stiles & J. S. Snow, 1984) as a measure of session depth. In line with Bowlby's hypothesis, the findings suggest that session depth is related to the client's experience of attachment security with the counselor and that counselor global attachment moderates the relationship between client global attachment and session exploration.

Postdictors of eyewitness errors: can false identifications be diagnosed?

Eyewitness researchers have "postdicted" identification accuracy using witness confidence (S. L. Sporer, S. Penrod, D. Read, & B. Cutler, 1995), response latency (S. L. Sporer, 1993, 1994), and endorsement of statements consistent with using relative versus absolute judgment strategies (D. Dunning & L. B. Stern, 1994; R. C. L. Lindsay & K. Bellinger, 1999). All of these measures were collected from 321 introductory psychology students who had viewed a staged crime and completed a lineup identification task. Some participants received feedback after identification (G. L. Wells & A. L. Bradfield, 1998). Lineup fairness was also used as a postdictor of eyewitness accuracy. Discriminant function analysis indicated that 75.2% of choosers and 63.0% of nonchoosers were correctly classified. Decision time and lineup fairness were the best postdictors of accuracy. The implications for postdicting real eyewitness decisions are discussed.     

Using response time measures to assess "guilty knowledge"

How can a suspect's guilt or innocence be reliably tested? The validity of the polygraph, which measures changes in physiological arousal during a "guilty knowledge" test, is controversial (e.g., T. R. Bashore & P. E. Rapp, 1993; T. P. Cross & L. Saxe, 1992; D. T. Lykken, 1998; J. P. Rosenfeld, 1995; R. Steinbrook, 1992). One alternative to the polygraph examines event-related potentials recorded during a memory interference task (L. A. Farwell & E. Donchin, 1991). The present study extended this paradigm to determine whether response times (RTs) can accurately identify participants possessing specific guilty knowledge. Results from Experiment 1 showed that RT alone can reliably discriminate "guilty" from "innocent" participants. Experiments 2a and 2b indicated that an RT-based paradigm is more resistant to strategic manipulation than previously suggested (Farwell & Donchin, 1991). This RT-based paradigm may be a viable alternative to the polygraph for detecting guilty knowledge.     

The role of suggestions and personality characteristics in producing illness reports and desires for suing the responsible party

For this project, 92 students entered an abandoned theater room in an old basement of the university where sand was scattered throughout. The purpose of the study was to experimentally demonstrate that psychological suggestions could produce illness reports and to explore who is most likely to say that they would sue for personal damages. The students filled out the Trait-State Anger Scale and two subscales, Anger Temperament and Anger Reaction (C. D. Spielberger, G. A. Jacobs, S. Russell, & R. S. Crance, 1983) as well as the Costello-Comrey Anxiety Scale (G. C. Costello & A. L. Comrey, 1967), the Hardiness Inventory (S. C. Kobasa, 1982), the Pennebaker Inventory of Limbic Languidness (J. W. Pennebaker, 1982), and, embedded in the Hardiness Inventory, measures of current illness as a result of exposure to the basement room. Half the participants were met by a confederate student who claimed to be cleaning up the remains of a production of "Lawrence of Arabia," and the other half were met by a confederate construction worker who claimed that "The stuff will tear up your skin and your lungs." Those in the experimental groups who perceived danger and scored low in the hardiness dimension of challenge were more likely to report symptoms of illness. Willingness to file a law suit was predicted by a model including perceived danger and the personality characteristic of anger reactivity.     

Understanding academic attitudes and achievement in mexican-origin youths: ethnic identity, other-group orientation, and fatalism

This study tested the relationships among ethnic identity, other-group orientation, fatalism, and 2 dependent variables: attitude toward education and school, and grade point average (GPA). Mexican-origin adolescents (N = 222) completed the Multigroup Ethnic Identity Measure (J. S. Phinney, 1992), the fatalism scale of the Multiphasic Assessment of Cultural Constructs-Short Form (I. Cuellar, B. Arnold, & G. Gonzalez, 1995), and the attitude scale of the Learning and Study Strategies Inventory-High School (C. E. Weinstein & D. R. Palmer, 1990a). Other-group orientation was positively related to attitude and GPA, and a negative relationship between fatalism and attitude was demonstrated. No relationship emerged between ethnic identity and the dependent variables.
