强迫症诊断研究的新变化

临床实践与相关研究表明,强迫症的诊断标准已不能满足复杂的临床工作需要。首先,有关患者的自知力以及主观痛苦程度等诊断指标需要进一步修订。其次,就强迫症的核心症状而产生的争议,研究者提出应重新考虑强迫症、焦虑障碍、强迫谱系障碍和囤积障碍这四个概念之间的从属关系和诊断标准。未来研究应考虑从认知神经科学的视角探索强迫症的核心症状和病理机制,为强迫症的诊断标准提供新的依据。     

Project ABLE

This paper describes a proposed model for the management of Army soldiers rendered ineffective due to inadequate skills in coping with life stress. The history of Army mental health programs is reviewed to establish the rationale for program development. The proposed treatment methods and staffing are discussed. The application of this peacetime treaetment model in the management of combat psychiatric casualties is presented. Emphasis is placed on the role of the Army occupational therapist as a professional skilled in the use of task-directed behavior to enhance daily living skills.     

Body image in social anxiety disorder,obsessive–compulsive disorder,and panic disorder

Body dysmorphic disorder falls under the category of obsessive–compulsive and related disorders, yet research has suggested it may also be highly associated with social anxiety disorder. The current study examined body image variables among 68 outpatients with primary obsessive–compulsive disorder (OCD; n = 22), social anxiety disorder (SAD; n = 25), and panic disorder (PD; n = 21). Participants filled out self-report measures of body image disturbance, attitudes toward one's appearance, and anxiety. Body image disturbance and attitudes toward appearance did not significantly differ between the groups. However, SAD symptoms predicted body image disturbance, Appearance Evaluation and Body Areas Satisfaction, and OCD symptoms predicted Appearance Orientation. These findings suggest that SAD and OCD may be associated with different facets of body image. Implications for the treatment of anxiety disorders and for future research are discussed.     

囤积症的行为心理特征及相关因素

囤积症是指过度获取和不能丢弃那些没有用处或失去价值的物品。这种行为通常会给患者本人及其家庭成员带来感情、躯体、财务、社会甚至法律方面的负面影响。对于囤积症的行为特征、心理特征及相关因素,学界已有大量的研究。近期,囤积症已被纳入DSM-5,这将有助于确定有持续性丢弃困难的个体,并对其予以帮助与干预。     

Differentiating Sexual Thoughts in Obsessive-Compulsive Disorder From Paraphilias and Nonparaphilic Sexual Disorders

Recurrent sexual thoughts characterize several different psychological disorders, most notably obsessive-compulsive disorder (OCD), paraphilias, and nonparaphilic sexual disorders (NPSDs). Many clinicians are aware of the rule of thumb that sexual thoughts in OCD are personally distressing, whereas sexual thoughts in paraphilias and NPSDs are not distressing to the individual experiencing these thoughts, and they rely on this heuristic to inform diagnosis. This is problematic because distress alone is not a reliable diagnostic differentiator; as a result, misdiagnosis is common. Given the negative consequences of misdiagnosis, including worsening of symptoms, treatment dropout, and potential harm to individuals experiencing these thoughts or those who are targets of these thoughts, the purpose of this paper is to help clinicians identify and differentiate repetitive sexual obsessions in OCD from repetitive sexual thoughts in paraphilias and NPSDs. A clinical case example is provided along with pivotal areas of questioning to aid in differential diagnosis.     

Psychiatric Disorders and Childhood Parental Loss in Obesity: Relationship with the Mode of Weight Gain

We assessed the association between psychiatric disorders, childhood parental loss, and weight gain mode in 150 obese patients seeking bariatric surgery and with a history of sudden or gradual weight gain mode. Subjects with sudden weight gain mode (47%) showed significantly higher bipolar II disorder (p < .001), childhood parental death (p < .01), and separation (p < .01), but lower pure hypomania (p < .001) prevalence than subjects with gradual weight gain mode. We found preliminary evidence that lifetime bipolar spectrum disorders and childhood parental loss may influence weight gain mode in obese subjects. These findings may contribute to predict patients’ weight trajectories and implement preventive interventions.     

对边缘性人格障碍亚型的研究

边缘性人格障碍是一种最常见的人格障碍。描述性精神病学、心理测验和精神分析的研究发现,边缘性人格障碍可能是由若干个异质性的亚群体组成,不同的亚群在症状表现、病因、心理病理机制、对治疗干预的反应和预后等方面可能都存在着很大的差异,可以根据不同的维度将其进行亚型分类,而使同一个亚群中的个体差异小于不同亚群之间的个体差异。     

Self-esteem in patients with borderline and avoidant personality disorders

This study compared self-esteem in patients with avoidant personality disorder (APD) and borderline personality disorder (BPD). Patients diagnosed with one or more personality disorders answered the questionnaire Index of Self Esteem as part of a comprehensive evaluation within the setting of a treatment trial. Our hypotheses were that (1) both patients with APD and patients with BPD would report low levels of self-esteem, (2) patients with APD would report lower self-esteem than patients with BPD. We further expected that (3) patients with higher levels of depression would report lower levels of self-esteem, but that (4) both borderline and avoidant personality pathology would contribute to explained variance in self-esteem beyond what would be accounted for by depression. All of our hypotheses were supported. The results from our study showed a significant difference in self-esteem level between the two personality disorders, patients with APD reporting lower self-esteem than patients with BPD. Subjects with both disorders were measured to have self-esteem levels within the range that presumes clinical problems. Self-esteem represents an important quality of subjective experience of the self, and the study of self-esteem in PDs can offer new and important knowledge of PDs as self-pathology.     

Internal Validity of the Disruptive Behavior Disorder Symptoms: Implications from Parent Ratings for a Dimensional Approach to Symptom Validity

A dimensional approach was used to evaluate the internal validity of the DSM-III-R ADHD-inattention, ADHD-hyperactivity/impulsivity, oppositional defiant disorder (ODD), and conduct disorder (CD) symptoms (i.e., whether a symptom has a stronger correlation with its own dimension than the other three). Parents rated 4,019 children between the ages of 2 and 19 on these symptoms. The results showed that 5 of the 6 inattention symptoms, 3 of the 4 hyperactivity symptoms, 1 of the 4 impulsivity symptoms, 6 of the 9 oppositional defiant disorder symptoms, and 8 of the 11 CD symptoms had significant internal validity. Confirmatory factor analysis (CFA) found support for inattention, hyperactivity/impulsivity, oppositional defiant, and conduct disorder dimensions. Multiple-group CFA also found support for factor pattern and loading invariance across gender. The implications of these results as well as the merits of the dimensional approach to symptom validity are discussed in the context of the DSM-IV changes in ADHD, ODD, and CD.     

Rates of abuse in body dysmorphic disorder and obsessive-compulsive disorder

Body dysmorphic disorder (BDD) continues to challenge professionals due to symptom severity, co-morbidity, suicidal ideation, and overvalued ideation. Despite the disorder's severity, little research exists. Clinical observation suggests a noteworthy history of abuse; therefore the present study investigated the reported rate of physical, sexual, and emotional abuse in BDD patients. OCD patients were chosen as a comparison group because BDD is considered to be an obsessive-compulsive spectrum disorder. A group survey design was used (N = 50 for each group). Results show significantly higher levels of emotional and sexual abuse in the BDD sample versus the OCD sample. No significant differences were found in physical abuse. Abuse may be a contributing factor in BDD, but not in OCD.     

Common Genetic and Environmental Influences on Major Depressive Disorder and Conduct Disorder

The evidence for common genetic and environmental influences on conduct disorder (CD) and major depressive disorder (MDD) in adolescents was examined. A sample of 570 monozygotic twin pairs, 592 dizygotic twin pairs, and 426 non-twin siblings, aged 12-18 years, was recruited from the Colorado Twin Registry. For the past year data, there was a significant correlation between the genetic influences on MDD and CD and, for the lifetime data, there was a significant correlation between the genetic influences on MDD and CD, and a significant correlation between the nonshared environmental influences on MDD and CD. Our results suggest that some genetic factors will increase an individual's vulnerability to both MDD and CD in adolescence.     

Identification of preschool children at risk for emotional and behavioral disorders: development and validation of a universal screening system

Three studies were designed to measure various indicators of the reliability and validity of the Preschool Behavior Screening System (PBSS) as a screening instrument for emotional and behavioral disorder risk status of children of preschool age. Study 1 and Study 2 served to establish evidence for content validity. Study 3 investigated one type of reliability evidence (i.e., internal consistency) and four types of validity evidence (i.e., internal structure validity, validity evidence based on external relations, concurrent validity, and cross-informant agreement).Teachers and parents of children (N = 113) enrolled in preschool and childcare programs completed Phase 1 and Phase 2 of the PBSS and the Behavior Assessment System for Children (BASC-2). Cross-informant agreement between parent and teacher ratings on the PBSS was generally moderate, and internal consistency was high. PBSS Phase 1 and PBSS Phase 2 were correlated in the expected directions, and sensitivity and negative predictive value were high. Results suggest that the PBSS may yield psychometrically sound scores for helping states meet child-find requirements. Directions for future development of the PBSS are provided.     

Do mental disorders moderate the association between diabetes status and alcohol consumption?

Although heavy alcohol consumption is associated with diabetes-related complications, little is known about patterns of alcohol use among people with diabetes. Moreover, heavy drinking is more common among individuals with major depressive disorder (MDD), bipolar disorder (BD), and generalized anxiety disorder (GAD) than in the general population, and these disorders are often comorbid with diabetes. The present study tested the hypothesis that mental disorders moderate the association between diabetes status and alcohol consumption. A total of 14,302 adult participants aged 40-79 were included from the cross-sectional 2012 Canadian Community Health Survey-Mental Health (1,698 with diabetes). Data were analyzed using hierarchical linear regression models. MDD and BD, but not GAD, significantly moderated the association between diabetes status and alcohol quantity, such that the presence of diabetes was strongly and negatively associated with alcohol quantity if individuals had MDD or BD. There was no interaction between diabetes status and any of the mental disorders and alcohol frequency. This study suggests that among individuals with diabetes, those with comorbid MDD or BD drink less than those without MDD or BD. Further investigation of this association is needed and could help inform future alcohol-related interventions among individuals with diabetes.     

Social problem-solving skills in boys with conduct and oppositional defiant disorders

The current study compared the social problem-solving skills of a clinic-based sample of 30 boys diagnosed with conduct disorder (CD) and 25 boys diagnosed with oppositional defiant disorder (ODD). Past research has indicated that contextual factors influence children's social problem-solving; thus, three hypothetical conflict situations (i.e., child-child, teacher-child, and parent-child) and situations which differed by degree of negative intent of the provocateur (i.e., hostile vs. Ambiguous intent) were examined. Problem-solving strategies were aggregated into three broad dimensions: 1) aggressive/antisocial solutions; 2) nonverbal-nonaggressive solutions; and 3) verbal-nonaggressive solutions. Compared to ODD boys, CD boys proposed more aggressive/antisocial solutions in parent-child conflicts when parental intent was ambiguous and in teacher-child conflicts regardless of intent. Compared to ODD boys, CD boys proposed fewer verbal-nonaggressive solutions in child-child conflicts. The implications of these findings for treatment intervention with CD and ODD boys were discussed. Aggr. Behav. 23:457–469, 1997. © 1997 Wiley-Liss, Inc.     

Effects of Deviant Child Behavior on Parental Distress and Alcohol Consumption in Laboratory Interactions

Levels of adult distress and ad lib alcohol consumption following interactions with child confederates were investigated in parents of children with no diagnosable psychiatric disorders. Sixty parents (20 married couples and 20 single mothers) interacted with boys trained to enact behaviors characteristic of either normal children or deviant children with externalizing behavior disorders — attention-deficit hyperactivity disorder (ADHD), conduct disorder (CD), and oppositional defiant disorder (ODD). Relative to the normal child role, interactions with deviant confederates were rated as significantly more unpleasant, resulted in feelings of role inadequacy, and produced significantly more anxiety, depression, and hostility. After the interactions, parents were given the opportunity to drink as much of their preferred alcoholic beverage as they desired while anticipating a second interaction with the same child. The participants consumed more alcohol following exposure to deviant as opposed to normal confederates.     

Parent and Child Agreement for Acute Stress Disorder,Post-Traumatic Stress Disorder and other Psychopathology in a Prospective Study of Children and Adolescents Exposed to Single-Event Trauma

Examining parent-child agreement for Acute Stress Disorder (ASD) and Post-Traumatic Stress Disorder (PTSD) in children and adolescents is essential for informing the assessment of trauma-exposed children, yet no studies have examined this relationship using appropriate statistical techniques. Parent-child agreement for these disorders was examined by structured interview in a prospective study of assault and motor vehicle accident (MVA) child survivors, assessed at 2–4 weeks and 6 months post-trauma. Children were significantly more likely to meet criteria for ASD, as well as other ASD and PTSD symptom clusters, based on their own report than on their parent’s report. Parent-child agreement for ASD was poor (Cohen’s κ = −.04), but fair for PTSD (Cohen’s κ = .21). Agreement ranged widely for other emotional disorders (Cohen’s κ = −.07–.64), with generalised anxiety disorder found to have superior parent-child agreement (when assessed by phi coefficients) relative to ASD and PTSD. The findings support the need to directly interview children and adolescents, particularly for the early screening of posttraumatic stress, and suggest that other anxiety disorders may have a clearer presentation post-trauma.     

Test of Alternative Hypotheses Explaining the Comorbidity Between Attention-Deficit/Hyperactivity Disorder and Conduct Disorder

There is significant comorbidity between attention-deficit/hyperactivity disorder (ADHD) and conduct disorder (CD). The conclusions of studies that examined the causes of comorbidity between ADHD and CD conflict, with some researchers finding support for the three independent disorders model and others finding support for the correlated risk factors model. We tested these models and eleven alternative hypotheses using the same analytical approach. The participants were 110 monozygotic twin pairs and 181 dizygotic twin pairs recruited from the Colorado Learning Disabilities Research Center Twin Study. The three independent disorders model did not fit the data, whereas the correlated risk factors model fit the data well. Several other comorbidity models fit the data as well as or better than the correlated risk factors model. The results suggest that correlated risk factors are a better explanation for the comorbidity between ADHD and CD than a third, independent ADHD+CD subtype.     

Memory transfer for emotionally valenced words between identities in dissociative identity disorder

The present study aimed to determine interidentity retrieval of emotionally valenced words in dissociative identity disorder (DID). Twenty-two DID patients participated together with 25 normal controls and 25 controls instructed to simulate DID. Two wordlists A and B were constructed including neutral, positive and negative material. List A was shown to one identity, while list B was shown to another identity claiming total amnesia for the words learned by the first identity. The identity claiming amnesia was tested for intrusions from list A words into the recall of words from list B and recognition of the words learned by both identities. Test results indicated no evidence of total interidentity amnesia for emotionally valenced material in DID. It is argued that dissociative amnesia in DID may more adequately be described as a disturbance in meta-memory functioning instead of an actual retrieval inability.

Paired-Associate Learning in Attention-Deficit/Hyperactivity Disorder as a Function of Hyperactivity-Impulsivity and Oppositional Defiant Disorder

A paired-associate learning (PAL) test was administered to 22 community volunteers without disruptive disorders and 197 children (7.5–13.5 years-old) presenting with the inattentive and combined subtypes of attention-deficit/hyperactivity disorder (ADHD) either in combination with or without oppositional defiant disorder (ODD). Participants were screened for learning disorders. In comparison to non-ADHD participants, children with ADHD achieved worse PAL and made errors rated as more acoustically and less semantically similar to the correct paired associates. These deficits were not related to hyperactivity–impulsivity or comorbid ODD. These results suggest that ADHD children are less competent at PAL and use less efficient learning strategies than their non-ADHD peers.
