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.     

Negative Affect in Victimized Children: The Roles of Social Withdrawal, Peer Rejection, and Attitudes Toward Bullying

This study evaluated the validity of mediating pathways in predicting self-assessed negative affect from shyness/social withdrawal, peer rejection, victimization by peers (overt and relational), and the attitude that aggression is legitimate and warranted. Participants were 296 3rd through 5th graders (156 girls, 140 boys) from 10 elementary schools. Self-report measures of victimization, attitudes, and negative affect, and a teacher-report measure of shyness/social withdrawal and peer rejection were completed during the spring semesters of 2 consecutive years. Hierarchical regression analyses supported the mediational model in predicting negative affect at Time 2. However, an increase in negative affect over the 12-month study period was best accounted for by direct effects of increased victimization and changes in attitudes/attributions regarding aggression. Implications for the planning of school interventions designed to interrupt these victimization-maladjustment pathways are discussed.     

Swimming against the mainstream: the early years from chilly tributary to transformative mainstream

This article traces the transformative paradigm shift in the theory and practice of personal change. Within a decade, new conceptual models, analytic methodologies and modes of treatment were created. Treatments were altered in the content, locus, and agents of change. This enterprising period also witnessed a sweeping shift in the public acceptance of behaviorally oriented treatments. The present article also analyzes the evolving theorizing and applications of social cognitive theory rooted in modeling, self-regulatory, and self-efficacy mechanisms of psychosocial change. This model of change is implemented from an agentic perspective to promote personal, institutional, and society-wide changes that address some of the most urgent global problems.     

Ego atrophy in substance abuse: addiction from a socio-cultural perspective

The use of intoxicants is indexed in American history adopting a social perspective of the role of alcoholism in traditional American society. Appealing to societal patterns, the elaboration of substance abuse as a disease is explored with a diagnostic focus on intervention as it relates to pathogenesis. Using clinical vignettes, the ego is proposed as the focus of pathology in the addiction process, featuring a regression to the defenses of projection and denial. Following the model proposed in Zinberg's seminal paper on addiction and ego function, various deficits are annotated that typify such regression. The ultimate clinical picture is one of ego atrophy, where basic interests and object relations are usurped by the all-consuming preoccupation with the substance of abuse.     

Knowing When Help Is Needed: A Developing Sense of Causal Complexity

Research on the division of cognitive labor has found that adults and children as young as age 5 are able to find appropriate experts for different causal systems. However, little work has explored how children and adults decide when to seek out expert knowledge in the first place. We propose that children and adults rely (in part) on “mechanism metadata,” information about mechanism information. We argue that mechanism metadata is relatively consistent across individuals exposed to similar amounts of mechanism information, and it is applicable to a wide range of causal systems. In three experiments, we show that adults and children as young as 5 years of age have a consistent sense of the causal complexity of different causal systems, and that this sense of complexity is related to decisions about when to seek expert knowledge, but over development there is a shift in focus from procedural information to internal mechanism information.     

早期亲子触觉经验促进个体社会性发展的心理机制

近期研究显示,早期亲子触觉经验和个体的社会性发展存在密切联系。关于这种联系产生的原因,已有研究多从神经科学的角度,探讨CT传入神经(C-tactile afferents)及有关环路在其间可能起到的作用。基于已有文献,本文将提出一个综合模型,系统阐述背后涉及的心理机制,着重论证亲子关系、个体探索行为以及与之关联的心理成分在其间扮演的角色,并在此基础上从研究设计的局限、有关变量关系的多元性以及未来可拓展方向对该领域研究进行进一步讨论和展望。     

The Evolution of Mindfulness‐based Cognitive Therapy

Metcalf and Dimidjian (this issue) present a timely review of the evolving evidence base and mechanisms of mindfulness‐based cognitive therapy (MBCT). The present commentary extends the discussion on the current evidence base for MBCT based on findings from recent meta‐analytic reviews in this field which attest to the promising outcome for mindfulness‐based therapies, particularly for depressed populations. However, the specific effects of MBCT as applied to anxiety, health and developmental populations is still very much in its infancy. The second objective of this commentary extends discussion on the transdiagnostic applications of MBCT versus traditional cognitive behavioural therapy (CBT). It is recommended that with the continuing expansion of MBCT, the effects of this therapeutic approach needs to be evaluated against other empirically supported therapies, including traditional CBT.     

Mechanisms of Change in Brief Couple Therapy for Depression

The goal of the present study was to investigate potential mechanisms of previously documented treatment effects for a brief, 5-session, problem-focused couple therapy for depression in a sample of 35 depressed women and their nondepressed husbands. The primary treatment effects were reducing women’s depressive symptoms and their husbands’ psychological distress and depression-specific burden. Secondarily, treatment resulted in increased relationship satisfaction for both partners. Given these significant treatment changes observed in 5 sessions, we sought to examine the mechanisms of change by testing the following three factors as potential mediators: (a) negative behaviors and attitudes toward depression, (b) support provision, and (c) empathic communication towards the depressed female partners. Women’s depression and husbands’ depression-specific burden were alleviated by positive changes in their illness-related attitudes and behaviors. Improvements in women’s marital satisfaction were also mediated by positive change in their illness-related attitudes and behaviors, along with perceptions of increased positivity and support from their husbands. Findings highlight the importance of targeting specific treatment agents in a brief couple therapy for depression such as psychoeducation about depression and support-building to increase partners’ understanding and acceptance of the illness, and teaching communication skills to reduce negative behaviors and criticism that are replaced by more empathic communication towards the depressed individual.     

Causal Networks or Causal Islands? The Representation of Mechanisms and the Transitivity of Causal Judgment

Knowledge of mechanisms is critical for causal reasoning. We contrasted two possible organizations of causal knowledge—an interconnected causal network, where events are causally connected without any boundaries delineating discrete mechanisms; or a set of disparate mechanisms—causal islands—such that events in different mechanisms are not thought to be related even when they belong to the same causal chain. To distinguish these possibilities, we tested whether people make transitive judgments about causal chains by inferring, given A causes B and B causes C, that A causes C. Specifically, causal chains schematized as one chunk or mechanism in semantic memory (e.g., exercising, becoming thirsty, drinking water) led to transitive causal judgments. On the other hand, chains schematized as multiple chunks (e.g., having sex, becoming pregnant, becoming nauseous) led to intransitive judgments despite strong intermediate links ((Experiments 1–3). Normative accounts of causal intransitivity could not explain these intransitive judgments (Experiments 4 and 5).
