Abstract

Despite the prevalence of sleep complaints among psychiatric patients, few questionnaires have been specifically designed to measure sleep quality in clinical populations. The Pittsburgh Sleep Quality Index (PSQI) is a self-rated questionnaire which assesses sleep quality and disturbances over a 1-month time interval. Nineteen individual items generate seven “component” scores: subjective sleep quality, sleep latency, sleep duration, habitual sleep efficiency, sleep disturbances, use of sleeping medication, and daytime dysfunction. The sum of scores for these seven components yields one global score. ...

Abstract

Purpose: To examine changes in readiness to quit and self-efficacy among adolescents who received a clinic-based, brief office intervention (BOI) for smoking cessation. Methods: This study utilized a prospective, pre-post- treatment design. Participants were adolescent smokers (34 females, 35 males) with a mean ± SD age of 15.8 ± 1.4 years; 86% were Caucasian, who were randomly assigned to receive the BOI as part of a larger clinical trial. They were recruited from three cities in the Midwest and Northeastern part ...

Abstract

This paper addresses methodological issues in the assessment of nicotine withdrawal and craving in clinical trials of smoking cessation therapies. We define withdrawal as a syndrome of behavioral, affective, cognitive, and physiological symptoms, typically transient, emerging upon cessation or reduction of tobacco use and causing distress or impairment of behavioral function. Offset effects (effects related to removal of a direct nicotine effect) are sustained effects of cessation or reduction of tobacco use that cause distress or impairment. Withdrawal and craving are ...

Abstract

The authors examined the factor structure of the Minnesota Nicotine Withdrawal Scale (MNWS) using confirmatory factor analysis in 3 clinical research samples of smokers trying to quit (N = 723). Three confirmatory factor analytic models, based on previous research, were tested with each of the 3 study samples at multiple points in time. A unidimensional model including all 8 MNWS items was found to be the best explanation of the data. This model produced fair to good internal consistency estimates. Additionally, ...

Abstract

Administered a scale designed to quantify hopelessness to 294 hospitalized suicide attempters, 23 general medical outpatients, 62 additional hospitalized suicide attempters, and 59 depressed psychiatric patients. The scale had a Kuder-Richardson-20 internal consistency coefficient of .93 and correlated well with the Stuart Future Test (SFT) and the pessimism item of the Beck Depression Inventory (BDI; .60 and .63, respectively). The scale was also sensitive to changes in the patient's state of depression over time, as evidenced by a correlation of .49 ...

Abstract

A prospective study of 1,958 outpatients found that hopelessness, as measured by the Beck Hopelessness Scale, was significantly related to eventual suicide. A scale cutoff score of 9 or above identified 16 (94.2%) of the 17 patients who eventually committed suicide, thus replicating a previous study with hospitalized patients. The high-risk group identified by this cutoff score was 11 times more likely to commit suicide than the rest of the outpatients. The Beck Hopelessness Scale thus may be used as a ...

Abstract

The Hamilton Anxiety Rating Scale, a widely used clinical interview assessment tool, lacks instructions for administration and clear anchor points for the assignment of severity ratings. We developed a Structured Interview Guide for the Hamilton Anxiety Scale (SIGH-A) and report on a study comparing this version to the traditional form of this scale. Experienced interviewers from three Anxiety Disorders research sites conducted videotaped interviews using both traditional and structured instruments in 89 participants. A subset of the tapes was co-rated by ...

Abstract

Purpose: A short form for situational temptations to drink scale was developed from an original 21-item inventory by Migneault. Methods: The form measured four hypothesized subscales of temptations on a sample of 348 college drinkers (66% female). Peer pressure, social anxiety, negative affect, and positive/social situations subscales were replicated and reduced. Results: Strong empirical support was found for a hierarchical model, indicating that the four subscales can be summed to provide a global measure of situational ...

Abstract

The need for a simply applied quantitative assessment of handedness is discussed and some previous forms reviewed. An inventory of 20 items with a set of instructions and response- and computational-conventions is proposed and the results obtained from a young adult population numbering some 1100 individuals are reported. The separate items are examined from the point of view of sex, cultural and socio-economic factors which might appertain to them and also of their inter-relationship to each other and to the measure ...

Abstract

A procedure for systematically evaluating and treating adolescents with known or suspected substance abuse is described. Integrating assessment with intervention affords the opportunity to comprehensively characterize the adolescent's problems and to quantitatively monitor treatment progress and outcome. ...

Abstract

The present study examines the psychometric properties of a verbal, face-to-face administration of the Childhood Trauma Questionnaire (CTQ) with female street-based sex workers (N = 171). Confirmatory Factor Analysis (CFA) indicated a poor fit between our data and the instrument's established 5-factor structure. Exploratory Factor Analysis (EFA) yielded four stable and usable factors corresponding to the Emotional Abuse, Emotional Neglect, Physical Abuse, and Sexual Abuse subscales of the CTQ; the Physical Neglect subscale did not emerge as a stable factor. Cross ...

Abstract

This study compared the survey responses of 280 current and former adolescent smokers for what they perceived would be helpful (or what had helped) in quitting smoking. The survey was developed from focus groups and was structured using Prochaska and DiClementes Stages of Change health behavior framework. Results showd that former smokers and current smokers in the preparation stage of change shared beliefs about the importance of interpersonal support, those who were contemplating a quit decision worried about obstacles and internal ...

Abstract

This study tested the hypothesis that higher rates of depression in adolescent girls are explained by their greater exposure and reactivity to stress in the interpersonal domain in a large sample of 15-year-olds. Findings indicate that adolescent girls experienced higher levels of total and interpersonal episodic stress, whereas boys experienced higher levels of chronic stress (academic and close friendship domains). Higher rates of depression in girls were explained by their greater exposure to total stress, particularly interpersonal episodic stress. Adolescent girls ...

Abstract

Constructed an adolescent expectancy questionnaire for use with 1,580 Ss aged 12-19 yrs. Expectancy factor structure was determined separately in 12-24 yr olds, 15-26 yr olds, and 17-29 yr olds, and in low- vs high-experience drinkers. Six expectancy factors repeated across all age groups: Physical Tension Reduction, Diversion from Worry, Increased Interpersonal Power, Magical Transformation of Experiences, Enhanced Pleasure, and Modification of Social-Emotional Behavior. Five of these were present in Ss with little or no drinking experience. Expectancy factor content became ...

Abstract

Describes the Social Support Questionnaire (SSQ) and 4 empirical studies employing it. The SSQ yields scores for (a) perceived number of social supports and (b) satisfaction with social support that is available. Three studies (N = 1,224 college students) dealt with the SSQ's psychometric properties, its correlations with measures of personality and adjustment, and the relation of the SSQ to positive and negative life changes. The 4th study (40 Ss) was an investigation of the relation between social support and persistence ...

Abstract

Background The majority of affective psychopathology is rooted early in life and first emerges during childhood and adolescence. However, little is known about how genetic vulnerability affects brain structure and function in childhood since the vast majority of studies published so far have been conducted on adult participants. The present investigation examined for the first time the effects of catechol-O-methyltransferase (COMT) valine (val) 158 methionine (met) (val158met) polymorphism, which has been shown to moderate predisposition to negative mood and affective disorders, on ...
