RESUMO
OBJECTIVE: Distress and low perceived social support were examined as indicators of psychosocial vulnerability in patients about to undergo heart surgery. DESIGN: A total of 550 study patients underwent heart surgeries, including bypass grafting and valve procedures. Psychosocial interviews were conducted about five days before surgery, and biomedical data were obtained from hospital records. MAIN OUTCOME MEASURES: Sociodemographic, personality, religious, and biomedical factors were evaluated as predictors of psychosocial vulnerability, and all five sets of variables were evaluated as contributors to hospital length of stay (LOS). RESULTS: Patients scoring higher on one or more indicator of presurgical psychosocial vulnerability were younger, more likely to be female, less likely to be married, less well educated, lower in dispositional optimism, higher in trait anger, and lower in religiousness. Older age, depression, low support, and low trait anger each showed an independent, prospective association with greater LOS, and several other predictors had prospective relationships with LOS that were statistically mediated by depression or perceived support. CONCLUSION: Evidence that multiple psychosocial factors may influence adaptation to heart surgery has implications for understanding and ameliorating presurgical distress and for improving postsurgical recovery.

OBJECTIVE: The purpose of this study was to examine the dimensionality, stability, and course of depressive symptoms over the 12-month period beginning approximately 1 week before heart surgery. METHODS: The Center for Epidemiological Studies Depression Scale (CES-D) was administered to 570 patients before heart surgery and 1, 3.5, 6.5, and 12.5 months later. RESULTS: Confirmatory factor analysis rejected a four-factor model as a result of small variances for two interpersonal items. With their elimination, a three-factor solution (negative affect, low positive affect, somatic/vegetative symptoms) showed good psychometric properties. Except for the somatic/vegetative factor at the 1-month follow up, there was a high degree of stability in the factor pattern over a 12-month period beginning approximately 1 week before heart surgery. Latent mean structure analysis indicated that, apart from elevations in several somatic/vegetative symptoms during the month after surgery, means for all three depressive symptoms declined over time. The recovery of positive affect showed a steeper trajectory toward the end of the follow-up period by comparison with the rates of decline for depressed affect and somatic/vegetative symptoms. CONCLUSIONS: These findings support using 18 CES-D items to measure three depressive symptom dimensions in heart patients and may reflect a normative pattern of adjustment to heart surgery.

OBJECTIVE: This study evaluated two brief personal feedback substance-use interventions for students mandated to the Rutgers University Alcohol and Other Drug Assistance Program for Students (ADAPS): (1) a brief motivational interview (BMI) intervention and (2) a written feedback-only (WF) intervention. A key question addressed by this study was whether there is a need for face-to-face feedback in the context of motivational interviewing to affect changes in substance-use behaviors or whether a written personal feedback profile is enough of an intervention to motivate students to change their substance use. METHOD: The sample consisted of 222 students who were mandated to ADAPS, were eligible for the study, and completed the 3-month follow-up assessment. Eligible students completed a baseline assessment from which a personal feedback profile was created. They were then randomly assigned to the BMI or WF condition. Students were followed 3 months later. RESULTS: Students in both interventions reduced their alcohol consumption, prevalence of cigarette and marijuana use, and problems related to alcohol and drug use between baseline and follow-up. There were no differences between the two intervention conditions in terms of any substance-use outcomes. CONCLUSIONS: The results suggest that, under these circumstances and with these students, assessment and WF students changed similarly to those who had an assessment and WF within the context of a BMI. Given the fact that the former is less costly in terms of time and personnel, written profiles may be found to be a cost-effective means of reducing alcohol and drug use and related problems among low- to moderate-risk mandated college students. More research is needed with mandated students to determine the efficacy of feedback interventions and to isolate the effects of interventions from the effects of being caught and being reprimanded to treatment.

According to the 'acquired preparedness model,' expectancies mediate the relationship between an impulsive personality style and alcohol use. The current study evaluated whether the model can also be applied to marijuana use. Estimated probabilities and subjective evaluations of personally expected marijuana effects, along with impulsivity and frequency of marijuana use, were assessed in 337 college undergraduates. Tests of mediation examining positive and negative marijuana expectancies showed negative expectancies to be a significant mediator for both males and females. That is, participants who were higher on impulsivity had fewer negative expectancies and in turn used more marijuana. This study provides evidence that the acquired preparedness model may help to explain marijuana use.

BACKGROUND: Cognitive impairments are frequently observed in clients who enter treatment programs for substance abuse. The potential for early recovery of cognitive abilities is suggested by previous research; however, the extent of improvement and risk factors that may help predict individual differences in rates of recovery remain unclear. This study is a 6-week follow-up and retest of an original sample of 197 men and women who had received a broad neuropsychological assessment at addiction treatment entry. The aim was to examine the potential clinical significance of changes in cognitive functioning and the extent to which differential recovery was predictable from client background information. METHODS: Fifteen neuropsychological tests were readministered to 169 of 197 clients 6 weeks after treatment entry. Structural equation modeling was used to estimate separately the practice effects and recovery in four cognitive domains: executive function, memory, information processing speed, and verbal ability. Client background information included age, sex, education, substance use and consequences, psychopathology, medical problems, familial alcoholism history, and childhood behavior problems. RESULTS: A four-factor model of latent neuropsychological ability that was previously identified at treatment entry was replicated at follow-up. Statistically significant increases in the means of the four latent abilities were found. Memory showed a medium effect size improvement. Executive function, verbal ability, and information processing speed, however, showed only small effect size improvements, suggesting limited clinical significance. Substance use between treatment entry and follow-up, antisocial personality disorder, negative use consequences, less education, and medical problems were modestly predictive of less recovery. CONCLUSION: Cognitive recovery in the first 6 weeks of treatment is possible, but, with the possible exception of memory, improvement may be minor in terms of clinical relevance.

Risk covariates of neuropsychological ability (NA) at treatment entry and neuropsychological recovery (NR) across 15 months were examined and replicated in 2 samples (Ns = 952 and 774) from Project MATCH, a multisite study of alcoholism treatments. NA at treatment entry was associated with age, education, and other covariates. Statistically significant mean increases in NA over time had small effect sizes, suggesting limited clinical significance of NR in the samples as a whole. However, initial NA and a combination of risk factors in direct and mediated pathways predicted a large proportion of individual differences in NR. Statistically significant but modest differential treatment effects on NR suggest that addiction treatments may need to be modified or developed to facilitate this important aspect of recovery.

OBJECTIVE: Summary prevalence data are critical to determining the utility of DSM-IV criteria for alcohol use disorders among adolescents. This study examined cross-study consistency in the relative prevalence of DSM-IV alcohol symptoms, the ratio of alcohol abuse to dependence diagnoses, the prevalence of the physiological dependence subtype, and the proportion of subthreshold cases of dependence. METHOD: DSM-IV alcohol diagnosis and symptom prevalence data were obtained from five community and four clinical adolescent samples. RESULTS: There was a moderate level of cross-study agreement on the relative prevalence of alcohol symptoms (mean Spearman p = 0.47). The most common symptoms were dependence criteria: tolerance and drinking more or longer than intended. A relatively high degree of variability in the ratio of abuse to dependence diagnoses and the proportion with physiological dependence was observed. All samples included a significant proportion of subthreshold cases of dependence: up to 12% in community and up to 34% in clinical samples. CONCLUSIONS: Alcohol dependence symptoms of tolerance and drinking more or longer than intended have relatively high prevalence among adolescents. These high prevalence symptoms affect the ratio of abuse to dependence diagnoses in some studies, the prevalence of the physiological dependence subtype, and the proportion of subthreshold cases of dependence.

The latent structure of neuropsychological abilities and risk factors for impairment were examined in 197 persons entering addictions treatment. Confirmatory factor analysis yielded 4 factors: Executive, Memory, Verbal, and Processing Speed. The measurement model was consistent with evidence that neuropsychological test performance is factorially complex and supported by multiple brain regions. Path analyses showed that risk factors explained 34%-57% of the true variance in abilities. Age, education, and medical status had the most generalized and robust associations with abilities. Drug use disorder diagnoses, childhood behavior problems, familial alcoholism, and psychopathology were also significantly related to specific latent abilities. Knowledge of neuropsychological impairment may be clinically useful, and selected risk factors may help treatment providers decide which clients should receive formal neuropsychological assessment.

BACKGROUND: A better understanding of the relationship of eating behavior and attitudes to weight loss following gastric bypass (GBP) will enable the development of interventions to improve outcome. Thus, the present study sought to characterize the postoperative weight, eating behavior, and attitudes toward body shape and weight in a cross-section of GBP patients. A second objective was to examine the relationship of postoperative binge eating to surgery outcome. METHODS: 99 patients who underwent GBP > 2 and < 7 years before the study start date completed the Eating Disorder Examination-Questionnaire (EDE-Q) and the Three-Factor Eating Questionnaire (TFEQ). Subjects self-reported their current body weight, weight change over the past 3 months, and lowest weight since surgery. RESULTS: BMI remained significantly below the preoperative level, but significant weight regain was reported at long-term follow-up. 46% of participants reported recurrent loss of control over eating (objective or subjective bulimic episodes) on the EDE-Q. These patients constituted a distinctive subgroup with a less favorable outcome, including greater weight regain. CONCLUSION: Self-reported loss of control over eating was related to weight regain after GBP and may be an important target for clinical intervention. The relationship of binge eating and related psychopathology to outcome following GBP warrants further investigation.
