HOW PSYCHIATRIC TREATMENTS CAN ENHANCE PSYCHOLOGICAL DEFENSE MECHANISMS

Psychological defense mechanisms are a powerful and often unappreciated force safeguarding mental health. Although rarely directed in this way, the most common forms of psychiatric treatment—psychotherapy and antidepressants—can enhance psychological defense mechanisms. Psychotherapy, through both specific and nonspecific factors, induces positive perspective shifts favoring positive cognitive distortions, including adaptive classical defense mechanisms and healthy attribution biases. Antidepressants, by altering very basic emotional information processing, such as facial expression recognition and emotional memories, also foster positive cognitive distortions. By shifting perceptions and thoughts in a positive direction, psychotherapy and antidepressants improve the capacity to dissociate from negative emotional stimuli.Brad Bowins, M.D., FRCP(C), is a staff psychiatrist at the University of Toronto Health Service and he is in private practice.     

Parental defense style and child competence: A match-mismatch hypothesis

This study sought to explore the possible relationship between parental style of psychological defense and children's social competence in 50 families in which one parent had been hospitalized for a psychiatric disorder. Based upon a formal analysis of the logical transformations inherent in various defense mechanisms, three levels of complexity of defenses were identified, along with a counterpart set of cognitive operations necessary for decoding these defense levels. It was hypothesized that children lacking the requisite cognitive skills to grasp the logical complexities of their disturbed parent's primary mode of psychological defense would be less socially adjusted and judged less competent than children who could understand the defensive transformations of their parent. The results suggested that children who, due to their cognitive immaturity, are potentially     

Body talk and body-related co-rumination: Associations with body image,eating attitudes,and psychological adjustment

Talk about physical appearance and body image is common among young women. We investigated how body talk (negative, positive/self-accepting, and co-ruminative) is related to body image, body-related cognitive distortions, disordered eating, psychological adjustment, and friendship quality via hierarchical regression analyses (controlling for social desirability and body mass index). In a sample of young adult women (N = 203), negative body talk was, as predicted, negatively related to body satisfaction and self-esteem and positively related to appearance investment, body-related cognitive distortions, disordered eating, and depression, but not friendship quality. Self-accepting/positive body talk was negatively related to body-related cognitive distortions and positively related to body satisfaction, self-esteem, and friendship quality. Body-related co-rumination demonstrated adjustment trade-offs, being related to body-related cognitive distortions, disordered eating, and higher friendship quality. Results indicated no advantage to negative body talk, both individual and relationship benefits from positive/self-accepting body talk, and mixed outcomes for body-related co-rumination     

Disturbed children's and adolescents' comprehension of psychological mechanisms of defense

This study examined the role of Piagetian logical and analytical reasoning in the comprehension of psychological defense mechanisms among 26 emotionally disturbed boys. Participants assigned to one of three Piagetian cognitive stages, listened to vignettes depicting defensive behaviors of various degrees of logical and structural complexity. Results indicated that, although both within- and between-group performances were at variance with theoretical expectations, consistent age trends in the comprehension of defense mechanisms were observed.

Stress,Coping and Adjustment in Victims of Sexual Assault: The role of psychological defense mechanisms

The paper considers sexual abuse within a stress and coping framework with particular emphasis on victim-initiated psychological defense mechanisms in the recovery process. Analysis of case history data from 40 adolescent victims of sexual abuse indicated that 90% used psychological defense mechanisms, particularly repression, emotional insulation and rationalisation. The paper explores the usefulness of such mechanisms from a theoretical and applied perspective and compares these Singaporean findings with earlier research conducted in the United States.     

Link between early maladaptive schemas and defense mechanisms

IntroductionDefense mechanism and early maladaptive schemas are two concepts distorting the perception of reality.ObjectiveThe aim of this study was to explore the link between two reality-distorting concepts from two theoretical models: early maladaptive schemas from the cognitive and behavioral model and defense mechanisms based on the psychoanalytic model.MethodTwo hundred thirty-two non-clinical participants completed the Defense Style Questionnaire and the Young Schema Questionnaire (short version). Then a Bravais Pearson correlation analysis connecting these two concepts, and a multiple regressions analysis using early maladaptive schemas as predictors for defense style mechanisms levels were conducted.ResultsThe results indicate that 2 early maladaptive schema domains (i.e. other-directedness as well as over-vigilance and inhibition) predict the frequency of use of the neurotic defense mechanism, and 3 schema domains (i.e. disconnection and rejection, impaired autonomy and performances as well as impaired limits) predict the frequency of use of the immature defense mechanism.ConclusionTo conclude, two psychological concepts based on two different theoretical models (psychoanalytic and cognitive and behavioral therapy) seem to share an important link justifying the use of integrative therapies such as schema therapy.     

Psychological factors and depressive symptoms in ischemic heart disease.

The aim of this study was to determine whether learned helplessness, cognitive distortions, self-efficacy, and dispositional optimism assessed at Time 1 (T1; questionnaires mailed at 1 month postdischarge) would predict depressive symptoms at Time 2 (T2; questionnaires mailed at 1-year follow-up) in a sample of 86 patients hospitalized with ischemic heart disease. Multiple regression results indicated that optimism and cognitive distortions at T1 were significantly associated with T1 depressive symptoms after controlling for confounding variables. When the T1 psychological factors were analyzed with T2 depressive symptoms, only optimism continued to predict depressive symptoms after controlling for confounds and T1 depressive symptoms. The global expectancies that optimism assessed appeared to be more stable over time than the statelike beliefs of cognitive distortions and may have accounted for why optimism predicted T2 depressive symptoms.     

The unified theory of repression

Repression has become an empirical fact that is at once obvious and problematic. Fragmented clinical and laboratory traditions and disputed terminology have resulted in a Babel of misunderstandings in which false distinctions are imposed (e.g., between repression and suppression) and necessary distinctions not drawn (e.g., between the mechanism and the use to which it is put, defense being just one). "Repression" was introduced by Herbart to designate the (nondefensive) inhibition of ideas by other ideas in their struggle for consciousness. Freud adapted repression to the defensive inhibition of "unbearable" mental contents. Substantial experimental literatures on attentional biases, thought avoidance, interference, and intentional forgetting exist, the oldest prototype being the work of Ebbinghaus, who showed that intentional avoidance of memories results in their progressive forgetting over time. It has now become clear, as clinicians had claimed, that the inaccessible materials are often available and emerge indirectly (e.g., procedurally, implicitly). It is also now established that the Ebbinghaus retention function can be partly reversed, with resulting increases of conscious memory over time (hypermnesia). Freud's clinical experience revealed early on that exclusion from consciousness was effected not just by simple repression (inhibition) but also by a variety of distorting techniques, some deployed to degrade latent contents (denial), all eventually subsumed under the rubric of defense mechanisms ("repression in the widest sense"). Freudian and Bartlettian distortions are essentially the same, even in name, except for motive (cognitive vs. emotional), and experimentally induced false memories and other "memory illusions" are laboratory analogs of self-induced distortions.     

Magnitude comparisons distort mental representations of magnitude

Many cognitive processes rely on representations of magnitude, yet these representations are often malleable (H. Helson, 1964; J. Huttenlocher, L. V. Hedges, & J. L. Vevea, 2000; A. Parducci, 1965). It is likely that factors that affect these representations in turn affect the psychological processes that rely on them. The authors conducted 4 experiments to investigate whether language-expressible magnitude comparisons distort mental representations of compared magnitudes. Participants compared magnitudes and estimated those magnitudes in a variety of tasks. Experiments 1 through 3 demonstrated systematic comparison-induced distortions. Experiment 4 demonstrated that comparison-induced distortions might account for the asymmetric dominance effect discussed in the decision-making literature. Potential effects of comparison-induced distortions on other psychological processes (e.g., density effects, order effects, body-size estimation, pain estimation, and consumer decision making) are discussed.

Irrational Expectations in the Job Search Process

Although approaches that focus on cognitive distortions are often used in psychological and career counseling, they are rarely used in job search counseling. Rational-Emotive Therapy (RET) can be used effectively to combat clients' unrealistic expectations in the job search process.     

An empirical look at the Defense Mechanism Test (DMT): reliability and construct validity

Although the Defense Mechanism Test (DMT) has been in use for almost half a century, there are still quite contradictory views about whether it is a reliable instrument, and if so, what it really measures. Thus, based on data from 39 female students, we first examined DMT inter-coder reliability by analyzing the agreement among trained judges in their coding of the same DMT protocols. Second, we constructed a "parallel" photographic picture that retained all structural characteristic of the original and analyzed DMT parallel-test reliability. Third, we examined the construct validity of the DMT by (a) employing three self-report defense-mechanism inventories and analyzing the intercorrelations between DMT defense scores and corresponding defenses in these instruments, (b) studying the relationships between DMT responses and scores on trait and state anxiety, and (c) relating DMT-defense scores to measures of self-esteem. The main results showed that the DMT can be coded with high reliability by trained coders, that the parallel-test reliability is unsatisfactory compared to traditional psychometric standards, that there is a certain generalizability in the number of perceptual distortions that people display from one picture to another, and that the construct validation provided meager empirical evidence for the conclusion that the DMT measures what it purports to measure, that is, psychological defense mechanisms.     

Defense mechanisms in psychology today. Further processes for adaptation

Although the concept of the defense mechanism was rejected from academic psychology for a number of years, recent empirical studies show renewed interest in defenses. Cognitive psychologists have confirmed the existence of unconscious psychological processes, a requisite for defenses. Developmental, personality, and social psychologists have all found evidence for defense mechanisms that explicate psychological functioning. The relevance of this new information for clinical practice is discussed.     

Day-to-day body-image states: prospective predictors of intra-individual level and variability

Most body-image research has focused on the trait level of body-image evaluation, often neglecting the momentary fluctuations many people experience in everyday life. The present prospective study investigated whether theory-relevant body-image measures, perfectionistic self-presentation, and eating attitudes would predict average day-to-day body-image levels and their intra-individual variability. A convenience sample consisted of 121 women from two universities. In Phase 1 of the study, participants completed an online battery of selected body-image and personality questionnaires. In Phase 2, participants went online to complete the dependent measure, the Body Image States Scale, once per evening over 10 days. As hypothesized, more favorable body-image state levels were associated with less investment in appearance for self-worth, less body-image disturbance, fewer body-image cognitive distortions, less disturbed eating attitudes, and lower body mass. Moreover, greater day-to-day body-image variability was predicted by greater psychological investment in appearance, more body-image cognitive distortions, and higher perfectionistic self-presentation. Implications and future directions for research are discussed.     

Effects of psychological defense on processing of neutral stimuli indicated by event-related potentials (ERPs)

The Defense Mechanism Test (DMT) is claimed to identify personnel with a high risk for accidents. A new explanation for why the DMT seems to predict performance when survival depends on split second decisions is proposed. Sixteen right-handed, adult male students were tested with the DMT and with an ERP paradigm (two sine wave tones, presented binaurally). Each subject was tested with a one-stimulus paradigm, and a passive and an active oddball paradigm. Under the passive oddball condition, High defensive subjects differed from Low, having significantly smaller N2 amplitudes (low immediate perception), and significantly larger P3 amplitudes (rely on later associative mechanisms). High defensive subjects seem to have less ability to perceive the environment correctly immediately. This slowness may be fatal when life depends on split second decisions. The fundamental neurophysiological difference may also be the basis for the very complex cognitive and perceptual mechanisms involved in psychological defense mechanisms.     

Seven Pillars of Defense Mechanism Theory

Defense mechanisms are cognitive processes that function to protect the individual from excessive anxiety or other negative emotions. They also protect the person from loss of self‐esteem and, in the extreme, the loss of self‐integration. Although past critics questioned the existence of defense mechanisms, recent research has supported seven basic tenets regarding defenses. These include: (1) defenses function outside of awareness; (2) there is a chronology of defense development; (3) defenses are present in the normal personality; (4) defense use increases under conditions of stress; (5) defense use reduces the conscious experience of negative emotions; (6) defense function is connected to the autonomic nervous system; (7) excessive use of defenses is associated with psychopathology. Research supporting the seven pillars of defense mechanism theory is described in this essay.
