Overall Defensive Functioning Research Articles

A group's level of defensive functioning affects individual outcomes in group psychodynamic-interpersonal psychotherapy.

We used an actor-partner interdependence model (APIM) to study the association between the individual group member and other group therapy members' defensive functioning on an individual group member's treatment outcome. We hypothesized that (a) more adaptive individual defensive functioning at pretreatment will be significantly related to better treatment outcomes (i.e., lower binge-eating and interpersonal distress) at 6 months post-treatment; and (b) more adaptive other group members' defensive functioning at pretreatment will be significantly related to better treatment outcomes at 6 months post-treatment. Participants (N = 136) were individuals with BED enrolled in group psychodynamic-interpersonal psychotherapy (GPIP). Participants completed attachment interviews and were assessed on interpersonal distress and days binged at pretreatment and 6 months post-treatment. The interview audio recordings were transcribed and used to code defensive functioning. We found that individual overall defensive functioning (ODF) scores at pretreatment were not significantly associated with binge-eating frequency or interpersonal distress at 6 months post-treatment. Other group members' mean ODF scores at pretreatment were significantly associated with individual interpersonal distress at 6 months post-treatment. However, the other group members' mean ODF scores were not significantly associated with individual binge-eating outcomes at 6 months post-treatment. Defensive functioning of other members of a therapy group may be particularly important for improving interpersonal functioning in individuals with BED.

Psychometric Properties of the Defense Mechanisms Rating Scales-Self-Report-30 (DMRS-SR-30): Internal Consistency, Validity and Factor Structure

Assessment of defense mechanisms has a longstanding history within the clinical psychology and psychopathology literature. Despite their centrality to clinical practice, there are few self-report measures that assess defenses and, those that do exist, have limitations in addressing individual defenses and levels of defensive functioning. To address this need, we investigated the psychometric properties of the Defense Mechanisms Rating Scale - Self-Report − 30 item (DMRS-SR-30) with a global, community sample of 1,539 participants who responded to an online survey about distress and coping. Exploratory factor analysis found a three-factor model for the DMRS-SR-30 – mature, mental inhibition and avoidance, and immature-depressive. Internal consistency was high for the Overall Defensive Functioning (ODF) and the three extracted factors with coefficient alphas ranging from .75 to .90. Examination of concurrent validity with a commonly used measure of defensive functioning found significant relationships in the predicted directions. The group of immature defenses had the strongest concurrent validity (r = .50). Finally, correlations with external criteria – including psychological distress and adverse childhood experiences – supported the convergent and discriminant validity of the DMRS-SR-30. The three factor structure of the DMRS-SR-30 has good psychometric properties. Limitations and directions for future research, as well as clinical implications, are described.

The Hierarchy of Defense Mechanisms: Assessing Defensive Functioning With the Defense Mechanisms Rating Scales Q-Sort.

The psychodynamic concept of defense mechanisms is nowadays considered by professionals with various theoretical orientations of great importance in the understanding of human development and psychological functioning. More than half century of empirical research has demonstrated the impact of defensive functioning in psychological well-being, personality organization and treatment process-outcome. Despite the availability of a large number of measures for their evaluation, only a few instruments assess the whole hierarchy of defenses, based on the Defense Mechanisms Rating Scales (DMRS), which arguably offers an observer-rated gold standard of assessment. The present article illustrates the theoretical and methodological background of the DMRS-Q, the Q-sort version of the DMRS for clinical use. Starting from the definition and function of the 30 defense mechanisms included in the hierarchy, we extracted 150 items that captured a full range of defensive manifestations according to the DMRS theory. The DMRS-Q set is described in this paper with reference to the DMRS manual. Directions are also provided for using the DMRS-Q online software for the free and unlimited coding of defense mechanisms. After each coding, the DMRS-Q software provides a report including qualitative and quantitative scores reflecting the individual’s defensive functioning. Qualitative scores are displayed as the Defensive Profile Narratives (DPN), while quantitative scores are reported as Overall Defensive Functioning (ODF), defensive categories, defense levels, and individual defense mechanisms. Syntax for the scoring is displayed in the results and a clinical vignette of a psychotherapy session coded with the DMRS-Q is provided. The DMRS-Q is an easy-to-use, free, computerized measure that can help clinicians in monitoring changes in defense mechanisms, addressing therapeutic intervention, fostering symptoms decreasing and therapeutic alliance. Moreover, the DMRS-Q might be a valid tool for teaching the hierarchy of defense mechanisms and increase the observer-rated assessment of this construct in several research fields.

Psychological Impact of Coronavirus Disease 2019 Among Italians During the First Week of Lockdown.

Pandemics and government-mandated quarantining measures have a substantial impact on mental health. This study investigated the psychological impact of the coronavirus disease 2019 (COVID-19) crisis on Italian residents during the first week of government-imposed lockdown and the role of defense mechanisms as protective factors against distress. In this cross-sectional study, 5,683 Italians responded to an online survey assessing socio-demographics, overall psychological distress, post-traumatic symptoms, and defense mechanisms using validated measures as the Symptom Checklist-90 (SCL-90), the Impact of Event Scale-Revised (IES-R), and the Defense Mechanisms Rating Scale-Self-Report-30 (DMRS-SR-30). Data were collected from March 13 to March 18, within the first week of lockdown in Italy. Results showed that younger age and female gender were associated with increased psychological distress. Having positive cases nearby, more days on lockdown, and having to relocate were also associated with greater distress. Higher overall defensive functioning (ODF) was associated with lower levels of depression (r = −.44, 95% CI −0.48, −0.40), anxiety (r = −.38, 95% CI −0.42, −0.35), and post-traumatic stress symptoms (PTSS) (r = −.34, 95% CI −0.38, −0.30). Conversely, less adaptive defensive functioning was related to greater affective distress across all domains. Each increased unit of ODF decreased the chances of developing post-traumatic stress symptoms (PTSS) by 71% (odds ratio = 0.29, p < 0.001, 95% CI.026,.032). The psychological impact of COVID-19 among Italians during the early weeks of government lockdown has been significant. The pandemic continues to have extraordinary mental health impact as it moves across the globe. Given the salience of defensive functioning in psychological distress, consideration of interventions that foster the use of more adaptive defenses may be an important component of building resilience amidst a pandemic.

Preliminary Reliability and Validity of the DMRS-SR-30, a Novel Self-Report Measure Based on the Defense Mechanisms Rating Scales.

Defense mechanisms are psychological factors that influence emotional distress and quality of life. There are a number of measures assessing the construct of defense mechanisms, but only few available instruments reflect the gold-standard theoretical hierarchical organization of defenses. We report on the development of a novel 30 item self-report questionnaire, the DMRS-SR-30, based on the parent instrument, the Defense Mechanism Rating Scales (DMRS). This study tested preliminary reliability and validity of the Italian version of the DMRS-SR-30. We first extracted 30 items from the DMRS Q-sort version (DMRS-Q) and adapted them for a self-reported format. We then applied the DMRS quantitative scoring algorithms to provide proportional scores for the 28 individual defenses and summary scores for seven defense levels and overall defensive functioning (ODF) scores. A dynamic interview was used for assessing participant’s defense mechanisms with the observer-rated DMRS and DMRS-Q. We examined internal consistency of the scales along with criterion, concurrent, convergent and discriminant validity among participants (N = 94) who completed the DMRS-SR-30, SCL-90, BDI, and IES-R. Results showed very good internal consistency for ODF (Cronbach’s alpha = .890) and the high adaptive defense level, whereas some subscales with few items had lower values. Correlation analyses between DMRS-SR-30 and the two DMRS-based observer-rated measures showed very good criterion and concurrent validity for ODF and moderate to high for defense levels subscales. Correlations between the DMRS-SR-30 ODF and SCL-90 GSI, BDI and IES=R (r = −.456, r= −.540, r = −.402, respectively, all p <.001), indicated good convergent validity. Despite the well-known limitations of self-report methods of psychodynamic phenomena, self-report measures are highly practicable for assessing large samples. The DMRS-SR-30 is the first self-assessed measure describing the whole hierarchy of 28 defense mechanisms and providing scores for ODF, defensive categories, defense levels, and individual defenses. Preliminary examination of the Italian version of the DMRS-SR-30 showed promising results of internal consistency, criterion and concurrent validity, and convergent validity and of the measure. Further validation is needed to confirm these findings and explore other aspects of validity and reliability.

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

BackgroundDefense 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. MethodsFor 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. ResultsOver 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. ConclusionsResults 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.

Resilience in Holocaust Survivors: A Study of Defense Mechanisms in Holocaust Narratives

ABSTRACTThere is extensive literature examining the psychological adaptation of survivors after the Holocaust, including studies of Holocaust narratives (HN). As a measure of psychological adaptation, defense mechanisms (DM) have been studied in various clinical samples, however, to date, not in Holocaust narratives. Using a standardized observer-rated measure, we assessed DM in Holocaust versus pre/post Holocaust narratives (other narratives [ON]) in 20 in-depth survivor interviews. Regarding individual DM, isolation of affect and self-assertion were statistically more frequent in the HN than the ON. High adaptive (mature) level defenses were more frequent in the HNs than the ON. Furthermore, the overall defensive functioning (ODF) was higher in the HN than the ON, contradicting previous findings showing lower defensive functioning in life-threatening situations. Possible explanations include differences in the nature of trauma, the time elapsed between the trauma and the interview, and the specificity of the sample. A qualitative overview with several examples from the narratives are also presented.

Changes in Defense Mechanism Functioning During Group Therapy for Binge-Eating Disorder

Objective: This study examined change in defensive mechanism functioning during group psychodynamic interpersonal psychotherapy (GPIP) for women with binge-eating disorder (BED). Procedure: Women with BED (N = 85) received 16 weeks of GPIP. Five group therapy sessions (sessions 1, 3, 8, 12, and 16) from each of the 12 groups were video recorded and transcribed. Participants were rated on an observer-based measure of defensive functioning, the Defense Mechanism Rating Scale (DMRS). Symptom outcomes were assessed pre- and posttreatment. Results: Overall defensive functioning (ODF) scores improved significantly during group treatment, with specific defense level improvements in high adaptive, major image distorting, and action defenses. The linear increase in ODF mediated a decrease in binge-eating episodes and depressive symptoms. Reverse mediation was also noted. A cubic growth curve best modeled ODF data such that ODF improved in the early stage, followed by a slower rate of improvement in the middle stage, and a further increase in rate of improvement at the end of treatment. Discussion: Change in defense mechanism functioning may be an important aspect of group psychotherapy that is related to improved symptoms for women with BED who receive GPIP. The cubic trend that represented nonlinear growth in ODF is consistent with psychodynamic theory and a stage model of psychotherapy.

Defence styles in a sample of forensic patients with personality disorder.

Ego defences, often considered central to clinical work, have received surprisingly little attention in the forensic literature. In this exploratory study, 114 male inpatients completed the Defence Style Questionnaire (DSQ) following their admission to a specialist personality disorder (PD) service. Change in DSQ scores over time was examined using mixed effects models for those (n = 48) remaining in treatment for at least 18 months. Defensive functioning at baseline was less mature in comparison with non-clinical norms, with two other non-forensic PD samples, and with a male paedophile sample, but was unrelated to criminal history. Axis II severity was negatively associated with overall defensive functioning (ODF). Antisocial PD was positively associated with a maladaptive defence style. Borderline PD was negatively associated with self-sacrificing defences. Avoidant PD was negatively associated with both self-sacrificing and adaptive styles. Non-completion of treatment was predicted by low ODF scores and high maladaptive defence style scores at baseline. ODF improved significantly over time in treatment and was predicted by strong antisocial and weak schizotypal PD pathologies. Defence style, as measured by the DSQ, appears to have the potential to inform assessment and measure change in this group of offenders.

Détresse psychologique, fonctionnement défensif et soutien social perçu chez des patients atteints d’un cancer de la prostate : une étude préliminaire

ObjectiveThe aim of our research was to evaluate emotional distress among patients with primary and localized prostate cancer and the difficulties in emotional regulation encountered by certain patients, through the quality of their defensive functioning and the perceived social support. MethodOur sample comprises 51 patients with primary and localized prostate cancer treated using radiotherapy with or without hormone therapy (mean age=69; sd=6). Psychological evaluation comprised a semi-directive interview and three clinical scales (Defense Style Questionnaire-60, Hospital Anxiety and Depression Scale, Perceived Social Support Questionnaire). ResultsOf 51, 23 patients (45 %) have a significant indicator of psychological distress (HAD≥13) which was linked with a poorer quality of the overall defensive functioning (ODF, DSQ-60), characterized by a resort more important to the less adaptive defensive levels and styles (“major distortion of the image”, “action”, “image distorting”, “affect regulating”). Moreover, patients with distress are less satisfied with informative and emotional supports provided by health-care professionals (PSSQ). Finally, we observe correlations between informative support satisfaction, on the one hand, and the emotional support satisfaction, on the other hand, with a better quality of the patients’ overall defensive functioning (ODF) and some of its dimensions (univariate analysis). ConclusionThe association between psychological distress felt by patients suffering from prostate cancer and a poorer quality of the defensive functioning reflects the vulnerability of certain patients with regard to their difficulty to cope with the emotional stress linked to the disease. Finally, their capacities to elaborate affects (mentalisation) and the role of health-care professionals in providing support and help to regulate emotions for them is questioned.

Defensive Flexibility and Its Relation to Symptom Severity, Depression, and Anxiety

Numerous studies have examined which individual defense mechanisms are related with mental health, and which are linked with psychopathology. However, the idea that a flexible use of defensive mechanisms is related to psychological wellbeing remained a clinical assumption, which this study sought to test empirically. A total of 62 (N = 62) outpatients participated in the study and were assessed with the Symptom Checklist-90R and the Social Adjustment Self-rated Scale. A subsample of 40 participants was further assessed using the Hamilton Depression (HAMD-21) and Anxiety scales (HAMA-21). The first therapy session of all participants was transcribed and rated using the Defense Mechanisms Ratings Scales (), and the Overall Defensive Functioning (ODF) score, which indicates the maturity of one's defensive functioning, was computed. An indicator of flexible use of defenses was also calculated based on the Gini Concentration C measure. Results showed that defensive flexibility, but not ODF, could predict anxiety scores. Symptom severity was predicted by both ODF and defensive flexibility, although in directions opposite to our predictions. Results suggest that defensive flexibility captures another aspect of an individual's functioning not assessed by the ODF, and that it is a promising new way of documenting defensive functioning.

Changes in Defensive Functioning in Completed Psychoanalyses: the Penn Psychoanalytic Treatment Collection

Theory predicts that patients completing psychoanalysis should improve in their dynamic functioning. The aim of this naturalistic study is to examine whether a sample of 17 subjects from the Penn Psychoanalytic Treatment Collection with completed, tape-recorded psychoanalyses demonstrated improvement in one dynamic aspect: their defense mechanisms. The pre-post effect size for the change in overall defensive functioning (ODF) of the sample was large (.76) and statistically significant (p = .01). The percentage of subjects who improved in their ODF (71%) was similar to that found by others who studied the same sample using general functioning measures. These findings provide the first empirical evidence to support a trait-like change in dynamic personality functioning in patients who have undergone psychoanalysis. Randomized controlled studies with homogeneous samples are needed to further confirm these findings.

Clinicians' defences: An empirical study

Clinicians' defence mechanisms are strategies used to manage the stress and the negative affects emerging during a therapy session. The first objective of the study is to adapt the defence mechanisms rating scales (DMRS), originally created by Perry for assessing patient defences, in order to evaluate clinician defences. The second objective is to explore the type of defence mechanisms used by clinicians in oncology. The third objective is to study the sensitivity of the instrument by assessing changes in defensive functioning after specific communication skills training (CST) in oncology. Participants (N=20) were oncology clinicians participating in oncology CST. The defence mechanism rating scales for clinicians (DMRS-C) was used to assess the use of the clinicians' defences before and after CST. The instrument showed promising preliminary psychometric properties. Numerous and very varied defences were coded in each session and corresponding to a great variety of defences. After CST, the clinicians' overall defensive functioning (ODF) increased. Considering the defences' levels, a decrease in the use of immature defences was observed. Taking into consideration the importance of clinicians' variables in treatment outcome, this instrument constitutes a promising way of assessing the clinician's strategies used to face the emotional difficulties emerging during the therapeutic encounter.

Gender Differences in Self-Reported Defense Mechanisms: A Study Using the New Defense Style Questionnaire-60

Studies have shown that men and women differ in their use of defense mechanisms (e.g. Cramer, 1991; Watson and Sinha, 1998). However, how and why this difference exists is still open to debate. The present study explores the relationship between gender and defenses using the Defense Style Questionnaire (DSQ-60; Trijsburg Bond, & Drapeau, 2003). As expected, no significant differences were found in Overall Defensive Functioning (ODF); however, men and women differed in their choice of defense style, defense level, and individual defense mechanisms. Evidence is provided to support the notion that while overall adaptivity of defenses is comparable, men and women rely on different defensive organizations during conflict-laden situations. We discuss the clinical relevance of these results in light of previous findings.

The relationship of patient defensive functioning and alliance with therapist technique during short-term psychodynamic psychotherapy

This study investigates the relationship of patient defensive functioning, therapeutic alliance and therapists' use of technical interventions in Short-Term Psychodynamic Psychotherapy (STPP; Book, 1998; Luborsky, 1984; Strupp & Binder, 1984; Wachtel, 1993). Participants in this study were 44 patients admitted for individual psychotherapy at a university based outpatient community clinic. Patient defensive functioning was assessed with the Defensive Functioning Scale (DFS) of the Diagnostic and Statistical Manual of Mental Disorders (4th ed.; DSM-IV; American Psychiatric Association, 1994). Therapeutic alliance was assessed using patient ratings from the Combined Alliance Short Form (CASF; Hatcher & Barends, 1996). External raters coded videotaped sessions using the Comparative Psychotherapy Process Scale (CPPS; Hilsenroth, Blagys, Ackerman Bonge & Blais, in press) to assess the use of Psychodynamic–Interpersonal (PI) and Cognitive–Behavioral (CB) techniques early (third or fourth session) in psychotherapy. Patient Overall Defensive Functioning (ODF) was found to predict therapists' overall use of PI interventions, as well as specific PI and CB interventions. Additionally, patients who utilized fewer adaptive defenses were found to receive more PI interventions in general. The implications of these findings for treatment planning and intervention are discussed. Copyright © 2006 John Wiley & Sons, Ltd.

Contribution of defensive functioning to the quality of working alliance and psychotherapy outcome.

We analyzed whether defense mechanisms changed and/or predicted outcome during brief dynamic psychotherapy (N = 43, max 40 sessions, Norwegian Multisite Study on Process and Outcome of Psychotherapy). Defenses were rated with the Defense Mechanism Rating Scales (DMRS, clinician-rated) and Defense Style Questionnaire (DSQ self-rated). Overall defensive functioning (ODF) as rated by DMRS changed significantly. We found that the initial ODF's neither predicted the quality of working alliance nor influenced the outcome. Symptoms improved most rapidly early in therapy, while defenses changed during the last half of therapy, consistent with the phase model of change.

A Pilot Study of Defenses in Adults with Personality Disorders Entering Psychotherapy

This study examined defensive functioning in adults entering open-ended dynamic psychotherapy and determined whether defenses predict retention at 1 year. Beginning at about the fifth session, 14 adults with personality and or depressive disorders entering open-ended dynamic psychotherapy had five therapy sessions audiotaped. The sessions were rated according to the Defense Mechanism Rating Scales, quantitative method. Interrater reliability of overall defensive functioning (ODF) and the number of defenses used per session were intraclass R = .85 and .83, respectively, whereas that of seven defense levels yielded a median of .625 (range .52 to .80). Stability of ODF across the five sessions was intraclass R = .48. The 11 subjects with personality disorders (PDs) used predominantly lower immature (49.3%) and neurotic (40.8%) level defenses. Subjects with borderline PD had significantly lower ODF than those with other PD types. Higher ODF was associated with remaining in treatment at 1 year, although this was confounded with a higher frequency of weekly sessions. Quantitative assessment of defenses demonstrated fair to excellent reliability and indicated that in the short term approximately half of defensive functioning reflects a stable repertoire, whereas the remaining variation may be due to occasion and error. PDs and especially BPD are characterized by a predominance of lower defenses. Higher defensive functioning was associated with twice-weekly sessions and retention in therapy at 1 year. In therapy, adjusting technique to the patient's defenses may improve retention and outcome.

Convergent and discriminant validity of overall defensive functioning.

We examined the validity of the construct of overall defensive functioning and its discrimination from standard diagnostic assessments. Within a multisite field trial, patients received intake diagnostic interviews by clinicians who made standard axis I through V diagnoses, then rated defense mechanisms using the Defense Mechanism Rating Scales (DMRS). Patients filled out self-report measures of distress and defenses, the SCL-90-R, and Defense Style Questionnaire (DSQ). Overall defensive functioning (ODF) scales were derived from both the DMRS and the DSQ. Overlap between clinical and self-report ratings of defenses was modest. By two different methods of factor analysis, followed by confirmatory factor analysis, clinical ratings of ODF were clearly discriminable from axis I, axis II personality disorders, current and usual global functioning, and subjective distress. ODF measured by the DSQ was not clearly discriminated from subjective distress ratings, consistent with the hypothesis that subjective distress may distort conscious derivatives of actual defensive processes. The DSQ alone probably should not be considered as a substitute for observer-rated assessment of defensive functioning, although further study of the issue is warranted.

Defensive Functioning Predicts Improvement in Major Depressive Episodes

We investigated the predictive effect of psychological defenses on the course of major depression in a subsample of psychiatric patients from a larger study. We tested the hypothesis that a group of eight defenses, associated with depression in previous research, would predict, outcome of major depression. After an intake interview, 37 patients were rated on all DSM-III-R Axes, the SCL-90-R, and 28 defenses, using the Defense Mechanism Rating Scales. At 6-month follow-up interview, SCL-90-R and Global Assessment and Functioning (GAF) were redetermined on 34 (92%), 16 of whom had major depression at intake. Overall Defensive Functioning (ODF) significantly predicted GAF at 6-month follow-up over and above initial level of global functioning and presence of a personality disorder. The group of eight defenses were identified more often (p = .068) in depressed patients who improved less than predicted by their initial functional status. The high adaptive level defense, self-observation, was identified more often in those who improved more than predicted by their initial status. Our findings support the theory of a hierarchy of defenses, and the mediating effects of specific low and high adaptive level defenses on the course of a major depressive episode. Further research should examine passive aggression, acting out, help-rejecting complaining, splitting of self-images, splitting of others' images, projective identification, projection, and devaluation in relationship to the onset, course, and treatment response of depressive disorders.
