Grief and Recovery: The Prevalence of Grief and Loss in Substance Abuse Treatment

Grief from various losses can underlie the process of recovery from substance abuse disorders. This study identified losses that clients encountered prior to abusing substances, losses that occurred as a result of addiction, and losses that occurred upon entering treatment.     

On the importance of being ethnic: coping with the threat of prostate cancer in relation to prostate cancer screening

The relation between coping with a possible prostate cancer diagnosis and screening behavior was examined in men from seven precise ethnic groups. Five coping styles differed in their likelihood of use across ethnic groups and had somewhat different associations with frequency of prostate-specific antigen (PSA) testing. As expected, PSA test frequency differed among men from different ethnic groups and was differentially predicted by coping styles. Analyzing the results using typical groups of White, Black, and Hispanic, rather than precise ethnic groups, obscured these results. Researchers investigating psychological variables in preventive health behaviors must analyze diversity within the framework provided by ethnic specificity. Such an approach will guide the development and provision of interventions that are more sensitive to the characteristics of specific ethnic groups of at risk men.     

Two languages, one developing brain: event-related potentials to words in bilingual toddlers

Infant bilingualism offers a unique opportunity to study the relative effects of language experience and maturation on brain development, with each child serving as his or her own control. Event-related potentials (ERPs) to words were examined in 19- to 22-month-old English-Spanish bilingual toddlers. The children's dominant vs. nondominant languages elicited different patterns of neural activity in the lateral asymmetry of an early positive component (P100), and the latencies and distributions of ERP differences to known vs. unknown words from 200-400 and 400-600 ms. ERP effects also differed for 'high' and 'low' vocabulary groups based on total conceptual vocabulary scores. The results indicate that the organization of language-relevant brain activity is linked to experience with language rather than brain maturation.     

The hoarding dimension of OCD: psychological comorbidity and the five-factor personality model

Although hoarding has been associated with several psychological disorders, it is most frequently linked to obsessive-compulsive disorder (OCD). The present study assessed hoarding obsessions and compulsions in 204 individuals with OCD, and evaluated how hoarding was related to obsessive-compulsive symptom severity, psychological comorbidity, and personality as measured by the five-factor model. Results indicated that hoarding in OCD is a dimensional variable that is positively associated with dysphoria, total number of lifetime Axis I disorders, and lifetime histories of bipolar I, PTSD, and body dysmorphic disorder. Hoarding was negatively correlated with the NEO-Personality Inventory-Revised (NEO-PI-R) factor of Conscientiousness and positively associated with the NEO-PI-R factor of Neuroticism. When all personality and psychopathology variables were entered into a regression equation, dysphoria, bipolar II disorder, Conscientiousness, age, and Extraversion emerged as significant predictors of hoarding severity. Recommendations are made for clinicians and for future research.     

Finding "meaning" in psychology: a lay theories approach to self-regulation, social perception, and social development

Much of psychology focuses on universal principles of thought and action. Although an extremely productive pursuit, this approach, by describing only the "average person," risks describing no one in particular. This article discusses an alternate approach that complements interests in universal principles with analyses of the unique psychological meaning that individuals find in their experiences and interactions. Rooted in research on social cognition, this approach examines how people's lay theories about the stability or malleability of human attributes alter the meaning they give to basic psychological processes such as self-regulation and social perception. Following a review of research on this lay theories perspective in the field of social psychology, the implications of analyzing psychological meaning for other fields such as developmental, cultural, and personality psychology are discussed.     

Deficits on the Continuous Performance Test within the schizophrenia spectrum and the mediating effects of family history of schizophrenia

Individuals with schizophrenia spectrum personality disorders (SSPD) and schizophrenia show similar cognitive impairments. The authors examined the contributions of SSPD symptoms and familial risk for schizophrenia to impairments on the Continuous Performance Test--Identical Pairs Version. Participants included 103 schizophrenia patients, 66 first-degree relatives (29 SSPD), and 103 community controls (26 SSPD) screened for family history of psychosis. Patients and SSPD relatives performed significantly worse than non-SSPD relatives and SSPD and non-SSPD community controls. No differences in performance were observed among non-SSPD relatives and SSPD and non-SSPD community controls. Results suggest a continuum in which risk for schizophrenia-related cognitive impairments is highest among patients and SSPD relatives, intermediate among non-SSPD relatives, and lowest among SSPD and non-SSPD community controls. Results suggest that SSPD in the absence of a family history of psychosis may be a phenocopy.
