Evaluation of defense mechanisms in adult patients with panic disorder: before and after treatment

Change in Defense Mechanisms During a Brief Cognitive Behavioral Therapy for Obsessive-Compulsive Disorder

ABSTRACT

Defense mechanisms (DMs) are strategies used by the individuals to protect the ego. Therefore, compulsive behaviors in obsessive-compulsive disorder (OCD) can be recognized as DMs. We analyzed how DMs changed in a brief cognitive behavioral therapy (CBT) for OCD. This was a quasi-experimental study with 92 OCD patients (aged 18-60 years). We used the Mini International Neuropsychiatric Interview to confirm OCD diagnosis, and we assessed the DMs with the Defense Style Questionnaire at three time points. Through a latent change score modeling, we found that the mature mechanism presented a constant change during the therapy. This mechanism increased in average 0.37 points at each measured moment of CBT, showing a linear trajectory. Neurotic and immature mechanisms showed no significant changes during therapy. The increased use of the mature mechanism can be an indicator of improvement in OCD treatment, showing that patients intensified their more adaptive responses to conflicts.

Trauma and defense style as response predictors of pharmacological treatment in panic patients

Background

As panic disorder (PD) has a chronic course, it is important to identify predictors that might be related to non-remission. The aim of this study is to verify whether history of trauma and defense style are predictors to pharmacological treatment response in PD patients.

Method

The sample was composed by 47 PD patients according to DSM-IV who were treated with sertraline for 16 weeks. Evaluations were assessed by the C.G.I. (Clinical Global Impression), the Hamilton-Anxiety Scale, the Hamilton-Depression Scale, the Panic Inventory and the DSQ-40 (Defense Style Questionnaire) at baseline and after treatment.

Results

Full remission was observed in 61.7% of the sample. The predictors significantly associated with non-remission were: severity of PD (p = 0.012), age of onset (p = 0.02) and immature defenses (p = 0.032). In addition, the history of trauma was associated with early onset of PD (p = 0.043).

Conclusion

Panic patients had as predictors of worse response to pharmacological treatment the early onset and the severity of PD symptoms as well as the use of immature defenses at baseline. This finding corroborates the relevance of the evaluation of factors that might affect the response so as to enable the development of appropriate treatment for each patient.

Disentangling within- and between-patient effects of defensive functioning on psychotherapy outcome using mixed models

Abstract There is a great need to identify predictors of treatment response, and the analysis of defense mechanisms is a promising approach. Defensive functioning may influence psychotherapy outcome in two ways: First, when it is generally higher or lower for some patients relative to others and second, as it shifts in individual patients over time. The present study examined both within- and between patient effects of defenses using hierarchical linear modeling. Forty-seven patients diagnosed with depression, anxiety, or adjustment disorders received 25 ± 3 sessions of integrative cognitive-behavioral therapy in a university outpatient clinic. The Defense Mechanism Rating Scale (DMRS) was used to assess defenses in the 1st, 8th, 16th, and 24th session and relate them to symptom severity of depression and anxiety. A higher number of adaptive defense mechanisms was associated with less severe depressive symptoms during treatment while a higher number of immature defenses was related to more severe depressive and anxiety symptoms. An increase in adaptive and a decrease in immature defenses over the course of treatment predicted symptom reduction of depression whereas a decrease in neurotic and immature defenses was associated with reductions in anxiety symptoms. Our results empirically support defensive functioning as a mechanism of change in psychotherapy.

Relationships of attention-deficit hyperactivity disorder with defense styles and harm avoidance among male inpatients with alcohol use disorder

INTRODUCTION

Patients with alcohol use disorder (AUD) use immature defense styles, and AUD is related with adult attention-deficit hyperactivity disorder (ADHD). Harm avoidance (HA) is related with both AUD and particularly inattentiveness (IN) dimension of ADHD.

AIM

The aim of the present study was to evaluate the relationship of defense styles with probable ADHD and severity of ADHD symptoms while controlling the effect of HA among male inpatients with AUD.

SETTINGS AND DESIGN

The present study with cross-sectional design was conducted at the Alcohol and Drug Research, Treatment and Training Center (AMATEM) of Bakirkoy Training and Research Hospital for Psychiatry Neurology and Neurosurgery in Istanbul.

STATISTICAL ANALYSIS

Chi-square test, independent samples t-test, multiple logistic and linear regression analyses, and multivariate analysis of covariance (MANCOVA) were used.

MATERIALS AND METHODS

Participants (n = 151) were evaluated with the Adult ADHD Self-Report Scale, the Defense Style Questionnaire, and the HA Dimension of the Temperament and Character Inventory.

RESULTS

HA (particularly HA-1 [anticipatory worry and pessimism]) and immature defense style (particularly acting out) predicted the presence of probable ADHD. In linear regression analysis, HA (particularly HA-1 and HA-4 [fatigability and asthenia]), high immature (particularly acting out), and low mature defense styles predicted the severity of ADHD symptoms. In MANCOVA, immature defense style predicted both the IN and the hyperactivity/impulsivity (HI) dimensions of ADHD, whereas HA and IN dimension and low mature defense style predicted HI dimension.

CONCLUSIONS

These findings suggest that immature defense style (i.e., acting out) is related with both the presence of probable ADHD and severity of ADHD symptoms, together with HA, which must be taken into account while treating patients with ADHD among male populations with AUD.

Comparison and change of defense mechanisms over the course of psychotherapy in patients with depression or anxiety disorder: Evidence from a randomized controlled trial

BACKGROUND

Defense mechanisms play an important role in the development and maintenance of both health and psychopathology. Research is still in the early stages of investigating the specific relationships among diagnostic groups and defense mechanisms along with their response to different treatment types.

METHODS

For the present study a total of 47 outpatients diagnosed with depression or anxiety disorders were randomized to receive 25±3 sessions of cognitive-behavioral therapy with integrated elements of either emotion-focused therapy (CBT + EFT) or treatment components based on self-regulation theory (CBT + SR). An observer-rated method, the Defense Mechanism Rating Scale (DMRS) was used to code transcripts of the 1st, 8th, 16th and 24th session to assess change in defensive functioning.

RESULTS

Over the course of therapy, overall defensive functioning (ODF) as well as adaptive defenses increased significantly, whereas maladaptive and neurotic defenses did not change. At the beginning of treatment, the proportion of adaptive defenses and ODF was significantly higher in patients diagnosed with anxiety disorders than in patients with depressive disorders. However, depressed patients exhibited greater improvement in their defensive functioning over the course of therapy.

CONCLUSIONS

Results support the view of defense mechanisms as a useful transdiagnostic and transtheoretical concept and supports the notion that change of defense mechanisms may be a relevant mechanism of change in psychotherapy.

The physician's quality of life: Relationship with ego defense mechanisms and object relations

OBJECTIVE

To assess whether ego defense mechanisms and object relations (the way an individual subjectively experiences his/her relationships with others) are related to quality of life among physicians.

METHODS

In this cross-sectional mail survey, 602 physicians from Botucatu, SP, Brazil, were sent a socio-demographic questionnaire, the Bell Object Relations and Reality Testing Inventory-Form O (BORRTI-O), the Defense Style Questionnaire-40 (DSQ-40), and the World Health Organization Abbreviated Instrument for Quality of Life Assessment (WHOQOL-BREF).

RESULTS

198 questionnaires (33%) with valid responses were obtained. High BORRTI-O scores (indicative of pathology) on the alienation, egocentricity and insecure attachment subscales were associated with reduced WHOQOL-BREF scores for the psychological health and social relationship domains. Immature ego defense mechanisms were associated with lower WHOQOL-BREF scores for all domains. No significant associations of WHOQOL-BREF scores with working hours, workplace or monthly income were observed in the study population

CONCLUSIONS

WHOQOL-BREF scores correlated with mature defense mechanisms and normal object relations, suggesting an association between psychological maturity and quality of life among physicians.

Defense style as a predictor of change in interpersonal problems among patients attending day treatment for personality disorder

BACKGROUND

Healthy interpersonal functioning, and a reduction of the distress associated with maladaptive interpersonal behavior, is a focus of treatment for personality disorder (PD). Patients with PD are also known to make a preferential use of immature defenses. We examined change in interpersonal problems as a critical outcome, and defense style as a predictor of this outcome.

METHODS

Consecutively admitted patients to a group-oriented day treatment (DT) program were recruited (N = 32). Predictor variables were represented by subscale scores from the 40-item Defense Style Questionnaire (DSQ-40); outcomes were represented by the global distress and interpersonal octant scores from the 64-item Inventory of Interpersonal Problems-Circumplex (IIP-C).

RESULTS

Significant inverse correlations were observed between Neurotic defenses and change in both interpersonal distress and problems associated with the Vindictive, Cold, Socially Inhibited, and Non-Assertive octants. Partial correlations, adjusting for baseline IIP-C scores, remained significant. Additional inverse relations between Neurotic defenses and improvement in the Domineering, Exploitable, and Overly Nurturant octants also emerged in the partial correlation analysis.

DISCUSSION

Neurotic defenses are oriented to "splitting off" the affective element of experience; in the case of patients with PD, this affective element may often involve hostility. An orientation to use of Neurotic defenses also appears to be more trait-like and thus resistant to change. The findings highlight developing skill in affective communication, and addressing maladaptive interpersonal behaviors in the here-and-now, as mechanisms of therapeutic change in DT of patients with PD.

LIMITATIONS

The sample was small and assessment of defense style and interpersonal problems relied on patient self-report.

Relationship of defense styles with history of childhood trauma and personality in heroin dependent inpatients

In the present study the defense styles were assessed in heroin dependent inpatients to verify whether they used less adaptive defense mechanisms compared to healthy controls and to evaluate if immature defense styles are related with childhood traumas, while controlling the effect of age, temperament and character on this relationship in male heroin dependent inpatients. Participants were consecutively admitted 109 male heroin dependent inpatients and 60 healthy controls. Patients were investigated with the Defense Style Questionnaire, the Childhood Trauma Questionnaire, and Temperament and Character Inventory. Heroin dependent patients were using immature defense style more, particularly acting-out and splitting, than the control group. Together with lower age, immature defense style discriminated heroin dependents from control group (lower age, and higher devaluation and splitting in second regression model). Lower physical neglect score was related with a mature defense style, whereas higher cooperativeness (C) and self-transcendence (ST) were related with a neurotic defense style and lower reward dependence (RD), self-directedness (SD) and higher ST and emotional abuse were related with immature defense style. These suggest that heroin dependents are using maladaptive immature defense styles more, which can be taken into account in the development of therapeutic programs for these patients. Also, immature defense style may mediate the relationship between childhood emotional abuse and some personality dimensions (lower RD, SD and higher ST) in heroin dependent inpatients.

Association between PPP1R1B polymorphisms and defense mechanisms in healthy Chinese-Han subjects

Defense mechanisms resulting from the interaction between biological factors and the environment have been established. In genetic studies, dopamine genes have been recognized to play an important role in the determination of defense mechanisms. DARPP-32 (dopamine- and cAMP-regulated phosphoprotein) plays a central role in the biology of dopamine-receptive neurons; its coding gene (PPP1R1B) has been linked to psychological and psychopathological traits. Here, we aimed to explore the association between PPP1R1B polymorphisms and defense mechanisms measured using the 88-item Defense Style Questionnaire in 400 healthy Chinese-Han subjects. Of the three polymorphisms examined, rs12601930 was associated with projection (P = 0.028) and splitting (P = 0.032), while rs3764352 was associated with splitting (P = 0.042). No significant association was found between rs879606 and defenses. When analyzed separately by gender, no significant association between defense mechanisms and PPP1R1B polymorphisms in males was observed. In females, however, rs12601930 was significantly associated with splitting (P = 0.018), and rs879606, with projection (P = 0.015), help-rejecting complaining (P = 0.030), and immature defense style (P = 0.031), while rs3764352 was not associated with any defense. The distribution of genotypes between the low- and high-scoring subgroups for each defense style showed no significant differences. Our results suggest that PPP1R1B polymorphisms are, at least partially, responsible for immature defenses.

Relationship between defense styles, alexithymia, and personality in alcohol-dependent inpatients

In the present study, the defense styles were assessed in alcohol-dependent patients to verify whether they used less adaptive defense mechanisms compared with healthy controls and to evaluate if immature defense styles (IDSs) are related with alexithymia, while controlling the effect of age, temperament, and character on this relationship in male alcohol-dependent inpatients. Participants were consecutively admitted 118 male alcohol-dependent inpatients and 60 healthy controls. Patients were investigated with the Defense Style Questionnaire, the Toronto Alexithymia Scale, and the Temperament and Character Inventory. The alcohol-dependent patients were using neurotic defense style, some IDSs (projection, acting out, splitting, and somatization) more, and the mature defense style humor less than the control group. Together with higher age, IDS discriminated alcohol dependents from the control group (higher age, acting out, and splitting and lower humor in the second regression model). Immature defense style was positively correlated with novelty seeking, harm avoidance, self-transcendence, difficulty in identifying feelings (DIF), difficulty in describing feelings, external oriented thinking, and total alexithymia score in the present study, whereas it was negatively correlated with self-directedness and cooperativeness. Mean scores of neurotic and IDS were higher in the alexithymic group than the nonalexithymic group, and alexithymia was correlated with some IDSs. Higher difficulty in describing feelings predicted mature defense style, higher harm avoidance and DIF predicted neurotic defense style, and lower cooperativeness and self-transcendence and higher DIF predicted IDS. These suggest that alcohol dependents are using maladaptive IDS more, which can be taken into account in the development of therapeutic programs for these patients. In addition, IDS seems to be related with alexithymia, particularly DIF factor, whereas low cooperativeness and high self-transcendence are significant covariants. Thus, these results could indicate the use of specific strategies in the clinical and psychotherapeutic management of patients with alexithymic feature and IDS.

Defense mechanisms in congenital and acquired facial disfigurement: a clinical-empirical study

It is of clinical interest to investigate the degree to which patients with facial disfigurement use defense styles. Therefore, 59 adults born with rare facial clefts, 59 patients with facial deformities acquired at an adult age, and a reference group of 141 adults without facial disfigurements completed standardized questionnaires. There was a significant difference between the group with and the group without disfigurements on immature defense styles, with the disfigured group using the immature style more frequently. There was a trend for the nondisfigured group to use more mature defense styles. No difference between congenital and acquired groups was seen on individual types of defense style. Self-esteem had the strength to differentiate mature and immature defense styles within our disfigured groups. The association of low self-esteem and the utilization of immature defense styles suggests that professional help may tailor treatment on discussing immature defense style and problems triggering or maintaining this style.

Can psychopharmacological treatment change personality traits in patients with panic disorder?

OBJECTIVE

The aim of this study was to evaluate the effects that a particular psychopharmacological treatment has on personality patterns in patients with panic disorder.

METHOD

Forty-seven patients with panic disorder and 40 controls were included in the study. The Mini International Neuropsychiatric Interview and Minnesota Multiphasic Personality Inventory were used to assess Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, diagnoses and personality traits, respectively. Patients were treated with sertraline for 16 weeks.

RESULTS

There was a significant decrease in the score on 8 of the 10 Minnesota Multiphasic Personality Inventory scales. In addition, neurotic triad and psychasthenia personality scores were higher among panic disorder patients, even during the posttreatment asymptomatic phase, than among controls.

CONCLUSION

In the asymptomatic phase of the disease, panic disorder patients present a particular neurotic/anxious personality pattern. This pattern, although altered in the presence of acute symptoms, could be a focus of research.

Defense style in panic disorder before and after pharmacological treatment

Whether or not the use of maladaptive defense style is a trait, as opposed to a state dependent phenomenon, in panic disorder (PD) is a topic still very much up for debate. The aim of the study was to verify whether PD patients, both before and after treatment, used different defense style than the control group. Sixty-one PD patients (recruited from an original sample of 90 patients) and 64 healthy controls were evaluated against the Structured Clinical Interview for DSM-IV disorders, the Symptoms Check List-90, the Hamilton Rating Scales for Anxiety and for Depression and finally the Defense Style Questionnaire-40 (DSQ). The patients were treated with paroxetine or citalopram and were evaluated monthly for one year to assess the remission. The DSQ was re-administered to the patients at the end of the study. Before treatment, PD patients used more neurotic and immature forms of defense than controls. After treatment, those in remission used the same defense styles as the control group, whereas non-remitters still used more immature defenses. However, all the aforementioned difference disappeared, after excluding the effect of symptom severity. Our data supports the hypothesis that the use of maladaptive defenses might be the consequence of PD: when subjects fall ill, their capacity to use mature adaptive defenses may diminish, but when they recover their defensive style returns to a greater maturity. The present results are however limited by the dropout rate (one third of patients did not complete the study) and the use of just one questionnaire to evaluate the complexity of defense styles.

The use of the defence style questionnaire in major depressive and panic disorders: a comprehensive meta-analysis

PURPOSE

The issue of defence mechanisms is of great importance in clinical practice. The aim of this meta-analysis is to compare different defence styles (Mature, Neurotic, and Immature), assessed using the three-factor defence style questionnaire (DSQ), in major depressive disorder (MDD), and panic disorder (PD) in order to evaluate potential differences in defence profiles among these disorders.

METHODS

We assessed all publications listed in PubMed, PsycINFO, ISI, and Lilacs databases focusing on DSQ defence styles in MDD and PD. To be included studies had to be published in English, to include psychiatric patients, to provide defence style mean scores, and to employ the three-factor DSQ versions. Data were entered into the Cochrane Collaboration Review Manager Software and analysed by RevMan version 4.2.

RESULTS

MDD patients reported significantly lower scores in Mature style and both MDD and PD patients reported significantly higher scores in Neurotic and Immature styles.

CONCLUSIONS

A dissimilarity between depressive and anxious profiles emerged, since the former profile was characterized by low Mature and high Neurotic and Immature scores while the latter by high Neurotic and Immature scores only. These results could indicate the use of specific strategies in clinical and psychotherapeutic management of patients with these diagnoses. Nevertheless, present results should be considered with caution because of the high heterogeneity of the studies and some weaknesses in the psychometric properties of the DSQ.

Differentiation of depression and anxiety groups using defense mechanisms

We examined whether participants in depressed and anxious groups could be classified correctly using observer and self-report measures of defense mechanisms. A sample of 1182 university students completed the Personality Assessment Inventory and those scoring in the clinical range on either depression or anxiety indices were selected for participation. In total, 25 participants met criteria for the depressed group and 94 met criteria for the anxious group. Individual defense scores from the Defense-Q and the Defense Style Questionnaire were separately entered into 2 stepwise discriminant analyses. After cross-validation, the Defense-Q and Defense Style Questionnaire analyses classified participants with 75.0% and 71.3% accuracy, respectively. The results indicated that depression and anxiety groups can be significantly differentiated by defense use alone. Important differences in defensive functioning between these groups were confirmed and differences between observer and self-report measures of defenses mechanisms and current challenges in defense research were highlighted.

Using the Defensive Style Questionnaire to evaluate the impact of sex reassignment surgery on defensive mechanisms in transsexual patients

Objective: To evaluate the impact of sex reassignment surgery on the defense mechanisms of 32 transsexual patients at two different points in time using the Defensive Style Questionnaire. Method: The Defensive Style Questionnaire was applied to 32 patients upon their admission to the Gender Identity Disorder Program, and 12 months after they had undergone sex reassignment surgery. Results: There were changes in two defense mechanisms: anticipation and idealization. However, no significant differences were observed in terms of the mature, neurotic and immature categories. Discussion: One possible explanation for this result is the fact that the procedure does not resolve gender dysphoria, which is a core symptom in such patients. Another aspect is related to the early onset of the gender identity disorder, which determines a more regressive defensive structure in these patients. Conclusion: Sex reassignment surgery did not improve the defensive profile as measured by the Defensive Style Questionnaire.

Defense style changes with the addition of psychodynamic group therapy to clonazepam in social anxiety disorder

Psychodynamic Group Therapy (PGT) and clonazepam are strategies to reduce symptoms of generalized social anxiety disorder (GSAD). The addition of PGT might lead to changes in defense styles. The objective of this study is to examine changes in defense styles when comparing clonazepam to psychodynamic group therapy plus clonazepam in GSAD during 12 weeks. Fifty-seven patients that met DSM-IV criteria for GSAD participated. social anxiety disorder symptoms were evaluated with the Liebowitz Social Anxiety Scale, and defense styles with the Defense Style Questionnaire. All defense styles changed overtime for both groups, especially mature defense style, which increased independently of the treatment allocation group. Regression analyses found that overtime there was a reduction in neurotic defenses in the combined group, whereas there was an increase in the clonazepam group. Neurotic defense style can change toward greater adaptiveness with the addition of PGT to clonazepam in GSAD, even in 12 weeks.

Common genetic, clinical, demographic and psychosocial predictors of response to pharmacotherapy in mood and anxiety disorders

The aim of this study is to summarize available knowledge about common genetic, clinical, demographic and psychosocial predictors of response to pharmacotherapy in mood and anxiety disorders. A literature search was carried out by using MEDLINE and references of selected articles. The search included articles published up to March 2008. The main genetic finding concerns the serotonin transporter gene promoter polymorphisms, the long variant of which seems to be related to a positive response to therapy in mood disorders and could also have a role in the treatment of anxiety disorders. Among other predictors, the main factors common to both classes of disorder are comorbid axis II disorders and early onset of illness, which are related to a worse response to therapy and concomitant good physical conditions, absence of earlier treatments, early administration and response to therapies, and higher self- directedness, which is related to a better outcome. Many common predictors have been identified and these seem to be related to features covering the totality of patients that go beyond specific characteristics of single disorders. Possible limitations and suggestions for future research based on a more integrated vision of human complexity are discussed.

Transtorno do pânico

OBJETIVOS: Revisar o transtorno do pânico (TP), considerando seus aspectos clínicos, epidemiológicos, diagnósticos e etiológicos, bem como os avanços no tratamento, uma vez que o TP é uma entidade nosológica acompanhada de importante prejuízo psíquico e funcional. MÉTODO: Foi realizada uma revisão narrativa da literatura nas principais bases de dados existentes (MEDLINE, PsychINFO e SciELO) e em livros-textos atualizados. RESULTADOS: Devido à sintomatologia predominantemente física desse transtorno, os pacientes geralmente procuram vários atendimentos clínicos até que o diagnóstico seja feito. Em função desses aspectos e da sua cronicidade, o TP está associado a elevados custos econômicos. O tratamento do TP pode ser feito com psicoterapia e/ou psicofármacos. As diversas abordagens terapêuticas são apresentadas com o nível de evidência de cada recomendação. Em virtude da cronicidade e morbidade do TP, pesquisas têm se voltado para o estudo de estratégias de prevenção já na infância. CONCLUSÕES: O TP é um transtorno crônico e com baixas taxas de remissão dos sintomas em longo prazo. Sendo assim, sugere-se que sejam delineados novos estudos para tratamento precoce dos transtornos de ansiedade ou mesmo para prevenção em crianças de risco.

Defense mechanisms and suicide risk in major depression

Past suicide attempt has been consistently reported to be the best predictor of future suicide attempt. The need to identify predictors that can be targets of therapy is of great importance. Coping styles and defense mechanisms have now been linked to suicide in numerous reports. In this study, we expand on past research by exploring differences in defense mechanism use between three groups: 1) without current suicide ideation/attempt; 2) with current suicide ideation/no attempt; and 3) with current suicide attempt. We also explored the contribution of covariates, such as symptom severity and past attempt. Seventy-five adult patients who were within 48 hours of hospital admission for current major depressive episode were recruited. Clinical interview was conducted to verify diagnosis and assess symptom severity. Patients completed the Defense Style Questionnaire within 48 hours of admission based on their current thoughts and beliefs. Logistic regressions were used to determine the best predictors of current suicide status. Consistently, the use of more image-distorting mechanisms was the best predictor of current suicide attempt. Symptom severity and past attempt were not significant predictors after controlling for influence of defense styles. Decreased use of image-distorting mechanisms in adult patients with major depressive disorder should be considered as a distinct target of therapy.

Defense mechanisms after brief cognitive-behavior group therapy for panic disorder: one-year follow-up

Changes in defense mechanisms have been shown in long-term psychodynamic treatment. The aim of this study was to examine the changes that occurred after brief cognitive-behavior group therapy in the defense style of panic disorder patients that had failed to respond to pharmacotherapy. Forty-seven patients participated in the study and severity of panic disorder was evaluated by Clinical Global Impression. Defense mechanisms were evaluated by the Defense Style Questionnaire. Patients decreased the use of maladaptive defenses after cognitive-behavior group therapy, and the change in immature defenses was maintained at 1-year follow-up evaluation (p = 0.022). These modifications were associated with reduction of symptoms (F = 0.359; p = 0.047). These findings are consistent with the hypothesis that defense styles are malleable in short-term treatment and are, at least partially, symptom-state dependent.

Do defense mechanisms vary according to the psychiatric disorder?

OBJECTIVE

The aim of this study was to evaluate the defense mechanisms used by depressive and anxious patients without comorbidities compared to those used by controls and to determine whether these patterns differ between diagnoses.

METHOD

The sample was composed of 167 psychiatric patients and 36 controls that were evaluated using the Defense Style Questionnaire 40. All subjects were evaluated through a clinical interview, and each evaluation was confirmed through the application of the Mini International Neuropsychiatric Interview, a structured psychiatric interview. We used ANOVA and discriminant analysis to assess differences between groups.

RESULTS

Neurotic defense mechanisms discriminated controls from all patients except those with social anxiety. Immature defense mechanisms differentiated controls from all patients, as well as distinguished depressive patients from panic disorder and obsessive disorder patients. The discriminant analysis indicated that depressive patients are characterized by projection, panic disorder patients by sublimation and obsessive-compulsive patients by acting out.

CONCLUSIONS

Depressive and anxious patients differ from other individuals in their use of defense mechanisms, and each diagnosis has a particular pattern. These findings could lead to the development of specific psychotherapeutic interventions.

Listening to Prozac, with the third ear: a psychoanalytic theory of psychopharmacology

A model of the mind, utilizing constructs from object relations theory, is developed that bridges the conceptual gap between brain functions, influenced by the chemical milieu interior, and the psychodynamic construction of states of mind. A theory of self-regulation and regulation of the self is derived from the archaic mutual psychophysiological regulation between infant and mother that permits the actualization of a metapsychological structure, the internalized "environmental" mother that interpenetrates with chemically alterable brain physiology. This structure forms the background mental matrix of all experience and is maintained/altered either by meaningful (selfobject) relationships or by chemical agents and/or self initiated behavior, which modify the psychophysiological matrix directly via physiology. Linking this construct with a theory of internal object relations derived from Kernberg, and, a body of research documenting state-dependent learning, a clinically applicable theory of the direct (not symbolic) effect of physical events on the construction of experience is realized.
