We applied different diagnostic rules for diagnosing personality disorders to the NESARC epidemiological study of over 40,000 individuals. Specifically, unlike previous NESARC publications, we required that each personality disorder criterion be associated with significant distress or impairment in order to be counted toward a personality disorder (PD) diagnosis. Results demonstrated significant reductions in prevalence rates for PDs (9.1% versus 21.5% using original NESARC algorithms), and thes

Temporal instability of affect is a defining characteristic of psychological disorders such as borderline personality disorder (BPD) and mood cycling disorders. Ecological momentary assessment (EMA) enables researchers to directly assess such frequent and extreme fluctuations over time. The authors examined 4 operationalizations of such temporal instability: the within-person variance (WPV), the first-order autocorrelation, the mean square successive difference (MSSD), and the probability of acu

Ecological momentary assessment (EMA; Stone & Shiffman, 1994) was used to characterize and quantify a dynamic process--affective instability in borderline personality disorder (BPD). Sixty outpatients (34 with BPD and affective instability; 26 with current depressive disorder but not with BPD or affective instability) carried electronic diaries for approximately 1 month and were randomly prompted to rate their mood state up to 6 times a day. Results indicated that BPD patients (a) did not report

Traditional self-report measures of psychopathology may be influenced by a variety of recall biases. Ecological momentary assessment (EMA) reduces these biases by assessing individuals' experiences as they occur in their natural environments. This study examines the discrepancy between trait questionnaire, retrospective report, and EMA measures of affective instability in psychiatric outpatients either with a borderline personality diagnosis (n = 58) or with a current episode of major depressive

Parallel analysis (PA) is recommended as one of the best procedures to determine the number of factors but its theoretical justification has long been questioned. The current study discussed theoretical issues on the use of eigenvalues for dimensionality assessment and reviewed the development of PA and its recent variants proposed to address the issues. The performances of 13 different PAs including PA with minimum rank factor analysis, revised PA, and comparison data method were investigated t

Alcohol and tobacco use covary at multiple levels of analysis, and co-use of the 2 substances may have profound health consequences. To characterize the motivationally relevant processes contributing to co-use, the current study used ecological momentary assessment (EMA) to examine the subjective consequences of naturally occurring simultaneous use of alcohol and tobacco. Current smokers who reported frequently drinking alcohol (N=259) used electronic diaries to monitor their daily experiences f

Impulsivity is a core feature of many psychiatric disorders. Traditionally, impulsivity has been assessed using retrospective questionnaires or laboratory tasks. Both approaches neglect intraindividual variability in impulsivity and do not capture impulsivity as it occurs in real-world settings. The goal of the current study was to provide a method for assessing impulsivity in daily life that provides both between-individual and within-individual information. Participants with borderline persona

We assessed the effect of DBT skills utilization on features of borderline personality disorder as measured by the Personality Assessment Inventory-Borderline Features Scale (PAI-BOR). Participants were outpatients (N = 27) enrolled in a dialectical behavior therapy (DBT) program in a university-affiliated community mental health clinic. Diary cards were collected each week to track self-reported skills use. At the beginning of each new skills training module, patients completed another PAI-BOR.

Past research shows that higher well-being is reported by adolescents who live in individualistic rather than collectivistic nations. Such cross-national differences may be due to the amount of autonomy support adolescents receive from authority figures. To examine this hypothesis, in the current study, 322 adolescents from Denmark, South Korea, and the United States completed self-report surveys that assessed adolescents' school and life satisfaction and their experience of autonomy support fro

Alcohol use may be viewed as an attempt (albeit maladaptive) to regulate negative emotional states. We examined associations between both negative and positive affects and alcohol use in outpatient women diagnosed with borderline personality disorder (BPD; n=74), a prototype of emotional dysregulation, as well as a psychiatric control group of women with current depressive disorder (major depressive disorder/dysthymic disorder [MDD\DYS]; n=50). Participants completed randomly prompted reports of

탐색적 요인분석은 심리척도의 개발 과정에서 가장 널리 사용되는 분석 방법이다. 탐색적 요인분석의 올바른 사용에 대한 여러 지침이 있지만 문항 단위의 요인분석에서 특별히 고려되어야 할 사항들은 상대적으로 덜 강조되어 왔다. 본 연구는 척도를 구성하는 문항이 갖는 일반적인 특성들, 예를 들어 문항의 낮은 신뢰도, 리커트 반응 양식의 문항이 보이는 서로 다른 왜도 등이 이들 문항들에 대한 탐색적 요인분석에서 어떻게 고려되어야 하는지를 강조하였다. 문항 단위의 요인분석에서는 검사 점수 단위의 요인분석에 비해 더 큰 표본크기와 요인당 더 많은 문항수가 필요하다는 것을 강조하였다. 피어슨 상관계수 대신 다분상관계수를 사용할 것을 제안하였고 주축요인법과 최소제곱법, 평행분석, 사각회전 등을 사용할 것 또한 강조하였다. 이와 같은 절차를 적용하기 어려울 때는 응답 선택지를 6점 이상으로 할 것을 제안하였다. 마지막으로 대학생들에게서 수집한 로젠버그 자존감 척도 자료에 대해 제안된 고려사항들을 반영

Clinical and population-based samples show high comorbidity between Substance Use Disorders (SUDs) and Axis II Personality Disorders (PDs). However, Axis II disorders are frequently comorbid with each other, and existing research has generally failed to distinguish the extent to which SUD/PD comorbidity is general or specific with respect to both specific types of PDs and specific types of SUDs. We sought to determine whether ostensibly specific comorbid substance dependence-Axis II diagnoses (e

We examined the latent structure underlying the criteria for DSM-IV-TR (American Psychiatric Association, 2000, Diagnostic and statistical manual of mental disorders (4th ed., text revision). Washington, DC: Author.) personality disorders in a large nationally representative sample of U.S. adults. Personality disorder symptom data were collected using a structured diagnostic interview from approximately 35,000 adults assessed over two waves of data collection in the National Epidemiologic Survey

Background and Purpose The brief version of the Seoul Neuropsychological Screening Battery (SNSB), the SNSB-Core (SNSB-C), has been developed. Although each subtest score of the SNSB-C provides information on different features of broad cognitive functioning or im pairment, a composite score is needed to identify the severity of global cognitive impairment. We aimed to develop and validate a composite score of the SNSB-C that would provide a normative-based summary score of global cognitive func

The results demonstrated that the CDT is a useful cognitive screening tool that is comparable with the Mini-Mental State Examination, and that simple CDT scoring systems are sufficient for differentiating patients with MCI and mild dementia from CN.
