Type A Personality,Self-Control,and Vulnerability to Stress

The Minnesota Multiphasic Personality Inventory-Adolescent (MMPI-A; Butcher et al., 1992) was released in 1992 and has rapidly become the most widely used objective personality assessment instrument with adolescents. Although the MMPI-A reduced or eliminated several problems associated with the use of the original MMPI (Hathaway &; McKinley, 1943) with adolescents, the MMPI-A does produce a high frequency of within normal limits basic scale profiles for individuals with substantial psychopathology including adolescents in inpatient psychiatric settings. To better understand the reasons for this phenomenon, we compared the item endorsement frequencies for the MMPI-A normative sample with results from two adolescent clinical samples, and these results were contrasted to the item endorsement frequencies for the MMPI-2 (Butcher, Dahlstrom, Graham, Tellegen, &; Kaemmer, 1989) normative sample and a clinical sample of adult psychiatric inpatients. Results showed that the MMPI-A contains a substantial number of items that do not show a significant difference in item endorsement frequency between normative and clinical samples. Furthermore, MMPI-A basic and content scales generally show a much lower percentage of effective items than do the corresponding scales for the MMPI-2. We discuss the findings in relation to the frequent occurrence of low range MMPI-A profiles in clinical samples and the potential usefulness of these results in future efforts to develop viable short forms for the MMPI-A.     

Parental Representations and Support-Seeking Behaviors Related to Dependency and Self-Criticism

Cognitive and interpersonal models of depression were integrated by examining the links between parental representations and the interpersonal behaviors of individuals at risk for depression. Study 1 assessed the quantity and type of social support associated with Dependency and Self-Criticism. Study 2 examined the parental representations related to these personality styles, in an effort to document cognitive variables that might contribute to interpersonal behaviors. Self-critics were found to be more dysphoric over a 21-day, self-monitoring period, made fewer requests for social support, and showed lower perceptions of support. Peers did not report providing less support to self-critics, but found them less expressive and did not know them as well. Study 2 found pervasive, negative parental representations associated with Self-Criticism providing a cognitive underpinning to social distancing. Dependent participants reported higher levels of support, which was corroborated by the peer reports. Study 2 found Dependency to be related to favorable representation of parents for friendly and submissive, but not hostile, situations. The impact of cognitive representations for interpersonal functioning is highlighted, and reciprocal processes between the two are discussed.     

Correlation between Changes in Stress-Induced Corticosterone Secretion and GR mRNA Levels

The current study was conducted to determine the potential relationship between stress-induced corticosterone secretion and corticosteroid receptor mRNA levels after 5 days of intermittent stress. In particular, we were interested in the rate at which animals terminate a stress response, and how this termination may be altered by repeated stress. Adult male Sprague-Dawley rats were subjected to either 5 days of restraint stress or 5 days of an unpredictable stress paradigm. Restraint-stress induced corticosterone secretion was measured on Days 1 and 5 in both groups, and animals were killed on Day 6. Glucocorticoid receptor (GR), and mineralocorticoid (MR) mRNA levels were determined using in-situ hybridization techniques. Five days of restraint stress caused an habituation of the plasma corticosterone response to stress measured 60 and 90 min post-stress initiation; this pattern of corticosterone secretion was not observed in the animals subjected to unpredictable stress. Five days of either stress paradigm did not alter MR mRNA levels measured within the hippocampus or GR mRNA levels within the hippocampus or the medial parvocellular division of the paraventricular nucleus of the hypothalamus (mpPVN). However, an individual's GR mRNA levels measured within the CA1/2 region of the hippocampus and the mpPVN were significantly correlated with the degree of habituation of the corticosterone response to stress measured on Day 5. This suggests that an increase in the rate of termination of the stress response and levels of GR within the hippocampus and mpPVN may be functionally related.     

Family Experiences and Self-Criticism in College Students: Testing a Model of Family Stress,Past Unfairness,and Self-Esteem

Marriage and Family Therapists and other mental health professionals are often unaware of the sexual activity of preadolescent girls. The reason for this is the lack of research reporting on the sexual behavior of these young people. Also, in many cases the family may attend therapy for an unrelated issue and the sexual activity goes unnoticed. The present paper is an exploration into the lives of pre-teenagers' (ages 8–13) sex lives as they reported them in Internet chat rooms. Research on the content of chat rooms on the Internet is practically non-existent regarding this age group. Based on reports from over 1,300 pre-teen girls over a five-year time period, the results indicate that for some young girls, their young lives are filled with sexual behavior of one sort or another. They appear to be well versed in sexual terms and behaviors. In some cases the girls are forced into sexuality by a relative; in other cases, they appear to engage freely in sex with their boyfriends; in yet other cases they are forced by an older male. The girls overwhelmingly report that their parents are unaware of their sexual chatting on the Internet, even though it occurred regularly throughout the day. These girls are at risk. They are at risk for pregnancy and for sexual transmitted diseases, including HIV, not to mention the concomitant psychological effects. The data also indicate that the girls do not think about the consequences of their sexual behavior. Birth control and condom use appear not to be issues of concern for these young girls. Given the increased accessibility and use of the Internet by young people and the ability to create private spaces, blogs, and soon which are often sexual in nature, it is important for marriage and family therapists to understand the level of sexualization of some of these young girls in order to better address their needs and the needs of their families.     

A Lifespan Perspective on Dependency and Self-Criticism: Age-Related Differences from 18 to 59

A sizeable body of research suggests that self-definition and relatedness represent two fundamental developmental streams across the lifespan (Blatt in Psychoanal Study Child 29:107–157, 1974; Blatt and Luyten in Dev Psychopathol 21:793–814, 2009). Adverse developmental experiences have been found to affect personality development leading to high levels of self-criticism or dependency. No research to date has examined the developmental trends of these factors across the lifespan or the moderating impact of important life experiences. In a sample of 3,586 Canadians aged 18–59, age-related differences in self-criticism and dependency were examined. Analyses were replicated in a multicultural sample of 612 Canadians and 647 individuals born and currently living on the continent of Asia. Controlling for both neuroticism and depressive symptoms, results showed that self-criticism and dependency decreased linearly across the lifespan in both samples and across cultures; however, the decrease in self-criticism was steeper for men compared to women, while the decrease in dependency was steeper for those without children compared to those with children. Furthermore, participants who were in a romantic relationship showed lower levels of self-criticism and higher levels of dependency compared to those who were not in a romantic relationship. Results suggest that people may develop a healthier view of close relationships with others and acquire more positive self-views over the course of their lives.     

Rumination in Response to Stress as a Common Vulnerability Factor to Depression and Substance Misuse in Adolescence

The current study examined rumination in response to stress as a common vulnerability factor to both depression and substance use problems in adolescence. Specifically, we used a multi-wave longitudinal design to examine whether adolescents who tend to ruminate in response to stress exhibit increases in depressive symptoms and substance misuse following the occurrence of negative events. At time 1, adolescents (n = 161) completed measures assessing depressive symptoms, substance misuse, and the tendency to ruminate in response to stress. Every 6 weeks for the next 18 weeks participants completed measures assessing the occurrence of negative events, depressive symptoms, and substance misuse. Hierarchical linear modeling analyses indicated that adolescents who tend to ruminate in response to stress report greater elevations in depressive symptoms and substance misuse following elevations in negative events than other adolescents. The relationship between rumination, negative events, and substance misuse was moderated by age. Support was not obtained for fluctuations in depressive symptoms as a mediator of the relationship between negative events and substance misuse. Fluctuations in negative affect, however, were found to mediate this relationship.

Parental Overprotection,Perceived Child Vulnerability,and Parenting Stress: A Cross-Illness Comparison

The current study sought to investigate differences in parenting capacity variables across four disease groups. Parents (N = 425), the majority of whom were mothers, of children with either cancer, asthma, Type 1 diabetes, or cystic fibrosis, completed measures of parental overprotection, perceived child vulnerability, and parenting stress. After controlling for significant demographic variables, parents of children with cystic fibrosis and asthma reported higher perceived child vulnerability than parents of children with either diabetes or cancer, while parents of children with asthma and diabetes reported higher parenting stress than parents of children with cancer or cystic fibrosis. No differences between disease groups were found for parental overprotection. The current study provides support for an illness-specific approach to understanding parenting capacity variables in the context of childhood chronic illnesses.     

Taming the Brain Weasels: Reducing Self-Criticism Through Externalization and Compassion

ABSTRACT

Self-criticism is a natural process occurring across mental health disorders. When self-criticism is excessive, vulnerability to mental health disorders such as depression and anxiety increases. Compassion-focused approaches can effectively address a variety of concerns; however, highly self-critical individuals might balk at the idea of self-directed compassion due to shame, self-blame, or discomfort with positive emotions, resulting in treatment resistance. The brain weasel is an intervention strategy that uses the Narrative Therapy technique of externalization as an intermediate step toward compassion-oriented work. Through creative externalization and therapeutic humor, self-critical individuals can decenter and explore their self-critical dialogue. This article contains several ways to introduce and use the brain weasel personification in counseling.     

Stress-Induced Binge Eating: A Behavior Analytic Approach to Assessment and Intervention

Responses to acute or chronic stress may include behaviors, such as alcohol consumption, cigarette smoking, and altered eating patterns. In connection with the stress-eating relation, some researchers have suggested that certain stressors (e.g., psychological or emotional) may influence the direction (i.e., increase or decrease) of a person’s eating response. In a recent study, Connors and Morse (Int J Eat Disord 13:1–11, 2006) indicated that the physical and psychological stress associated with sexual trauma could result in an increase in food intake and nonstandard eating patterns. In consequence, this study describes a multifaceted intervention for a 24-year-old woman who experienced chronic stress and received a diagnosis of Binge Eating Disorder (American Psychiatric Association (1994). Diagnostic and statistical manual of mental disorders. DSM-IV. Washington, DC: APA) following a series of unwanted sexual experiences. The behavior analytic intervention emphasized self-control, self-regulation, and physical activity. The treatment package resulted in a 19% reduction in the participant’s body weight, a 96% reduction in binge eating, and long-term adherence to an exercise routine.     

Temperament and Vulnerability to Psychopathology: Introduction to the Special Section

Several authors have highlighted associations with temperament as promising avenues for understanding vulnerability to psychopathology (e.g., Muris and Ollendick, Clinical Child and Family Psychology Review, 8, 271–289, 2005; Nigg, Journal of Child Psychology and Psychiatry, and Allied Disciplines, 47, 395–422, 2006). The successful integration of models of temperament and models of psychopathology will undoubtedly increase our understanding of both. The current special section intends to present important new ideas and evidence in this field and tries to formulate answers to a couple of emerging questions. To set the stage for the papers, we provide a brief state of the art of research on temperament—psychopathology associations. After that, we discuss emerging questions in the field, some of which are addressed in the papers of this special section. To conclude, we point out a couple of future research perspectives.     

Mindfulness-Based Cognitive Therapy for Neuroticism (Stress Vulnerability): A Pilot Randomized Study

Objective: Neuroticism, a characteristic associated with increased stress vulnerability and the tendency to experience distress, is strongly linked to risk of different forms of psychopathology. However, there are few evidence-based interventions to target neuroticism. This pilot study investigated the efficacy and acceptability of mindfulness-based cognitive therapy (MBCT) compared with an online self-help intervention for individuals with high levels of neuroticism. The MBCT was modified to address psychological processes that are characteristic of neuroticism. Method: Participants with high levels of neuroticism were randomized to MBCT (n = 17) or an online self-help intervention (n = 17). Self-report questionnaires were administered preintervention and again at 4 weeks postintervention. Results: Intention-to-treat analyses found that MBCT participants had significantly lower levels of neuroticism postintervention than the control group. Compared with the control group, the MBCT group also experienced significant reductions in rumination and increases in self-compassion and decentering, of which the latter two were correlated with reductions in neuroticism within the MBCT group. Low drop-out rates, high levels of adherence to home practice, and positive feedback from MBCT participants provide indications that this intervention may be an acceptable form of treatment for individuals who are vulnerable to becoming easily stressed. Conclusions: MBCT specifically modified to target neuroticism-related processes is a promising intervention for reducing neuroticism. Results support evidence suggesting neuroticism is malleable and amenable to psychological intervention. MBCT for neuroticism warrants further investigation in a larger study.     

Vulnerability to depression: reexamining state dependence and relative stability

Treatment-related decreases in Dysfunctional Attitudes Scale (DAS; Weissman & Beck, 1978) scores have been interpreted as evidence that dysfunctional attitudes are state-dependent concomitants of depression. Data from the National Institute of Mental Health Treatment of Depression Collaborative Research Program were used to reexamine the stability of dysfunctional attitudes. Mean scores for Perfectionism, Need for Approval, and total DAS decreased after 16 weeks of treatment. However, test-retest correlations showed that the DAS variables displayed considerable relative stability. Structural equation models demonstrated that dysfunctional attitudes after treatment were significantly predicted by initial level of dysfunctional attitudes as well as by posttreatment depression. The relative stability of dysfunctional attitudes was even higher during the 18-month follow-up period. The results were consistent with Beck's (1967) and Blatt's (1974) theories of vulnerability.     

抑郁的人格易感性：概念、理论与发展

抑郁人格易感性的研究主要围绕依赖-自我批评,社会性依赖-自主以及完美主义等概念展开。目前该方向的理论和研究不仅涉及抑郁易感人格的特点与结构,还探讨了人格与压力情境、抑郁的关系,易感人格与一般人格、特定抑郁症状的关系,人格易感性的不适应性本质等问题,文章对此进行了回顾。今后的研究除了应当在已有方向上深入探究之外,还应当考虑在不同文化背景下对人格易感性采用自下而上的方式重新考察,以及将人格与认知易感性研究相结合等新思路     

Age-Related Changes in Plasma Catecholamine Responses to Acute Swim Stress

Young adult (3 months) and aged (22 months) Fischer 344 male rats were prepared with chronic tail artery catheters. Three days after surgery, rats were exposed acutely to swim stress at 20, 25, 30, or 35°C for 15 min. Blood samples were obtained from each rat under basal conditions, at the end of the swim stress episode, and 15, 30, and 45 min after swim stress. Basal plasma levels of norepinephrine and epinephrine (EPI) were similar for 3- and 22-month-old rats. In contrast, plasma catecholamine responses of aged rats were significantly greater than those of young adult rats following swim stress at 20 and 25°C. Plasma catecholamine responses were similar for rats of the two ages following swim stress at 30 or 35°C. These findings indicate that aged rats have exaggerated sympathetic-adrenal medullary responses to acute swim stress at the lower water temperatures. Given the modulatory effects of plasma EPI on memory, these age-related alterations in plasma catecholamine responses to acute swim stress may influence spatial memory performance of rats in the Morris water maze.     

In Vivo Hippocampal Acetylcholine Release During Exposure to Acute Stress

Hippocampal extracellular acetylcholine (ACh) and choline levels were evaluated using in vivo microdialysis in male Fischer 344 rats before, during, and following an 80-min exposure to two different stress conditions. Measurements were taken in rats restrained and immersed in a water bath containing either 37 degreesC (normothermic-restraint) or 20 degreesC (cold-restraint) water. Results were compared to normothermic-freely-moving rats. Cold-restrained rats displayed decreased ACh levels during cold exposure relative to both normothermic-restrained and normothermic-freely-moving rats. By the end of the cold exposure period and following removal from cold, ACh levels had returned to near-baseline values. Normothermic-restrained rats had levels similar to those of normothermic-freely-moving rats, except for a marked increase in ACh following removal from restraint. Cold-restrained rats displayed a gradual elevation in choline levels during cold stress, followed by a gradual decline after stress termination, whereas both normothermic-restrained and normothermic-freely-moving rats displayed gradual decreases during the microdialysis session. These findings demonstrate that central cholinergic neurotransmission can be altered by the application of, and removal from, acute stressors. In addition, the results suggest a possible relationship between the magnitudes of both the stressor and its cholinergic consequences.
