A critical review of assessment strategies to measure the behavioral activation model of depression

Behavioral activation (BA) treatments for depression are based on a model of psychopathology indicating that losses of, reductions in, or chronically low levels of positive reinforcement produce behavioral and emotional changes in depression. The corresponding mechanism theory is that using BA techniques to increase activation will lead to a subsequent increase in positive reinforcement, which will decrease depressive symptoms. We attempt to review BA literature relevant to its psychopathology and mechanism models, paying particular attention to attempts to measure activation as conceptualized within BA treatments and attempts to measure reinforcement. Suggestions on ways in which to improve these measurements in order to better evaluate the psychopathology and mechanism models are provided.     

Trauma and PTSD in patients with alcohol, drug, or dual dependence: a multi-center study

Background:  We investigated (1) the prevalence of posttraumatic stress disorder (PTSD) in treatment-seeking subjects with substance use dependence (SUD), (2) the association between comorbid PTSD and the severity and course of addiction and psychopathology, and (3) this association in patients with subsyndromal PTSD, and in trauma exposure without PTSD.
Methods:  In this cross-sectional study, 459 subjects in 14 German addiction treatment centers participated with alcohol-dependence (A) in 39.7%, drug-dependence (D) in 33.6%, or both (AD) 26.8%. The diagnostic measures included the International Diagnostic Checklists (IDCL), Posttraumatic Diagnostic Scale (PDS), Addiction Severity Index (ASI), and the Brief Psychiatric Rating Scale (BPRS). Associations between independent characteristics and outcomes were analysed by univariate and multivariate statistics.
Results:  25.3% of the subjects had PTSD confirmed by both IDCL and PDS with higher rates in the AD (34.1%) and D (29.9%) groups compared with group A (15.4%, p  < 0.001). In 22.8%, PTSD was subsyndromal (either IDCL or PDS positive) without significant differences between SUD groups, and 18.3% met PTSD trauma criteria A without PTSD (exposure). After controlling for SUD and gender, trauma subgroups significantly differed regarding the onset of alcohol-related symptoms ( p  < 0.02), numbers of previous admissions ( p  < 0.03), severity of SUD ( p  < 0.001), current craving ( p  < 0.02), and psychopathology ( p  < 0.001). We observed the worst outcome in PTSD, while trauma exposure had no effects.
Conclusions:  The prevalence of PTSD is higher in drug than in alcohol dependence. The more strictly PTSD is diagnosed (by interviewer and questionnaire) the more clearly are associations with characteristics of SUD. PTSD seems to be an independent risk factor for an unfavorable outcome of SUD.     

Psychosocial adjustment after epilepsy surgical treatment

Epilepsy is a matter of interest to several medical specialities: neurology, neurosurgery, pathology, psychiatry, and other fields of knowledge such as psychology and sociology. Although a high prevalence of psychopathological disorders is often reported among epileptic patients who are candidates for neurosurgery, this cannot explain the problems that may be experienced by patients after surgery. Numerous related aspects such as neurological, psychological and sociological factors cause disturbances. This study suggests that systematic psychological and social management might help in the transition from chronic disability to wellness by means of improved adjustment potential.     

Psychosocial Functioning,Personality, and Body Image Following Vertical Banded Gastroplasty

Background In addition to increased risks of morbidity and mortality, extreme obesity is substantially associated with psychosocial problems. Therefore, the ultimate goal of bariatric surgery should not only be reducing weight and counteracting comorbid conditions but also improving psychosocial functioning. In addition to being an important goal of bariatric surgery, enhanced psychosocial functioning may motivate patients to adhere to adequate health behavior to maintain the surgically established weight loss. Methods We evaluated early postoperative psychosocial functioning in several domains over time. Preoperatively as well as 6, 12, and 24 months after vertical banded gastroplasty, 104 patients were psychologically assessed using a semi-structured interview and psychological questionnaires focusing on psychosocial functioning, personality, and body image. Results Over time, we found significant changes in weight: 2 years excess weight loss was 58.6%. In addition, most aspects of psychosocial functioning showed significant improvements over time. However, initial improvements in depressive symptoms, sleeping problems, and neuroticism did not last. With respect to personality features, only short-term changes in self-esteem were found. The most robust improvements were seen in the case of body image. Finally, within the patient group, there was a wide variability in changes. Conclusion Vertical banded gastroplasty not only leads to considerable weight loss but also to significant improvements in psychosocial functioning. However, some improvements waned over time, and successful postoperative functioning did not apply to all patients.     

Childhood Maltreatment and Psychiatric Morbidity in Bariatric Surgery Candidates

Background This study used standardized assessments to evaluate the association between childhood maltreatment (i.e., emotional, physical, and sexual abuse and emotional and physical neglect) and Axis I and II psychiatric disorders in patients presenting for bariatric surgery. Methods Participants (N = 230) provided demographic information and completed the Childhood Trauma Questionnaire, short form. The Structured Clinical Interview for the DSM-IV was used to assess Axis I clinical disorders and Axis II personality disorders. Results Approximately 66% of participants had a history of childhood maltreatment. Individuals reporting childhood maltreatment had a greater number of lifetime Axis I diagnoses than did those without, although the effect for physical neglect was no longer significant after controlling for multiple comparisons. With respect to specific Axis I diagnoses, a history of emotional or sexual abuse was associated with increased rates of lifetime mood and anxiety disorder diagnoses. Emotional neglect also was associated with increased rates of mood disorder diagnoses, and physical abuse was associated with increased rates of substance use disorders. There was no significant association between childhood maltreatment and personality psychopathology. Conclusion This study confirms high rates of childhood maltreatment in patients presenting for bariatric surgery that are associated with increased prevalence of lifetime mood, anxiety, and substance use disorders. Future prospective studies should include evaluation of a broad range of mental health and childhood experiences to tease apart the nature of the relationships between these factors and their potential impact on post-surgical outcomes.     

Effects of a Community Toxic Release on the Psychological Status of Children

This study sought to determine the emotional effects of a major community toxic release on children in the exposed community while controlling for the potential effects of response bias. Controlling for the response bias inherent in litigated contexts is an advance over previous studies of toxic exposure in children. A randomly selected representative sample of Exposed children (n = 31) was compared to a matched Control group (n = 28) from a nearby, unexposed community. Symptoms and complaints were assessed via interview with the children and their guardians, surveys and checklists, and well-established psychological instruments. Even when biased responding was controlled the Exposed children experienced more psychological distress, more physical symptoms, and greater general concern over their physical functioning than the Controls. The Exposed children also reported some concern about their future health and cancer risk but usually only if asked. Limitations and future research directions are discussed.     

Substance use and quality of life over 12 months among buprenorphine maintenance-treated and methadone maintenance-treated heroin-addicted patients

The purpose of this study was to investigate the effects of methadone treatment and buprenorphine treatment on retention in treatment, urine drug testing results, psychiatric status, social adjustment, and quality of life among patients involved in long-term treatment with the cited medications. Two hundred thirteen patients (106 on buprenorphine treatment and 107 on methadone treatment) were enrolled in this open study at the 3rd month of their treatment and followed up until the 12th month; those who left the program before the end of the 3rd month of their treatment were not included in the study sample. The results of this study show statistically significant improvements in opioid use, psychiatric status, and quality of life between the 3rd and 12th months for both medications. This study suggests the long-term efficacy of methadone treatment and buprenorphine treatment on symptoms of opioid addiction and quality of life.     

Psychological Features in a German Sample of Female Cosmetic Surgery Candidates

Background Psychological processes are vitally important to understanding the rationale for cosmetic surgery. This study focused on three core psychological issues (self-esteem, body image, and psychopathology) in its investigation of patients undergoing cosmetic surgery preoperatively. Furthermore, it aimed to provide some data especially for a German sample of female cosmetic surgery patients concerning this subject. Methods A cross-sectional design was used to investigate and compare a sample of female cosmetic surgery candidates (n = 35) and a nonsurgical control group (n = 35) matched for central sociodemographic features (gender, region, confession) and controlled for age. These factors are known as covariates of body image. All psychological features were assessed by widely used self-report measures: the Rosenberg Self-Esteem Scale (RSES), the Evaluation of the Own Body Questionnaire (FBeK), and the Symptom Checklist 90 Revised (SCL 90-R). Results The results indicate no statistically significant differences between the two groups in any of the scores, except for the FBeK Accentuation of the Body subscale. Conclusions According to the findings, this lack of evidence for group differences in general psychosocial scales corresponds widely to findings of other empirical studies.
