Did lifetime rates of alcohol use disorders increase by 67% in 10 years? A comparison of NLAES and NESARC

Two nationally representative epidemiological samples (the National Longitudinal Alcohol Epidemiological Survey and the National Epidemiological Survey of Alcohol and Related Conditions) have been used to track changes in the prevalence of alcohol use disorders (AUDs) between 1992 and 2002 in the United States. Strikingly, estimates from these two data sets suggest that the lifetime prevalence of AUD increased by approximately 67% (from 18.2% to 30.3%) during this time frame. This article explores potential reasons for these discrepant estimates. Analyses indicated that a vast majority of change in lifetime AUD occurred with respect to alcohol abuse and not alcohol dependence. Most of this increase in abuse was attributable to self-reported changes in hazardous use that did not track with other archival measures of outcomes related to hazardous use in the population. Key methodological differences regarding the frequency requirements for prior-to-past-year alcohol abuse appeared to explain most of the discrepancy in lifetime AUD estimates. These findings, in conjunction with the relative lack of differences in the 12-month prevalence of AUDs, suggest that the discrepant lifetime estimates are likely due to methodological differences between the two surveys. These findings have important implications for substance use and other psychiatric surveillance and epidemiology where meaningful cross-temporal comparisons are desired.     

When a child dies: the sociobiology of bereavement

According to modern evolutionary theory, the fitness of individuals consists of both their personal reproductive success and the reproductive success of those with whom they share genes in common. It follows that one of the most biologically costly events possible is the death of a child. This study investigated the grief intensity of bereaved parents and their immediate families using ratings made by 263 bereaved parents. Predictions were derived from sociobiological tenets relating to parental investment, paternal uncertainty, and the propagation potential of both parents and children. Consequently, it was found that mothers grieved more than fathers, healthy children were grieved for more than unhealthy children; male children were grieved for more than female children; health of child and sex of child interacted such that the pattern of grief intensity obtained was healthy male greater than healthy female = unhealthy female = unhealthy male; similar children were grieved for more than dissimilar children; maternal grandmothers grieved more than either maternal grandfathers or paternal grandmothers, who in turn grieved more than paternal grandfathers; and mothers' siblings grieved more than fathers' siblings.     

Transactional models between personality and alcohol involvement: a further examination

Although correlated changes between personality and alcohol involvement have been shown, the functional relation between these constructs is also of theoretical and clinical interest. Using bivariate latent difference score models, we examined transactional relations (i.e., personality predicting changes in alcohol involvement, which in turn predicts changes in personality) across two distinct but overlapping developmental time frames (i.e., across college and during young adulthood) using two large, prospective samples. Across college, there was some evidence that alcohol involvement predicted changes in personality; however, these findings were limited to models that included more proximal measures of alcohol use. When examined across a longer timeframe, we found no evidence that alcohol involvement significantly predicted changes in personality but found some evidence that personality predicted changes in alcohol use. We did find reliable evidence of correlated changes between personality and alcohol use, especially during emerging adulthood. The findings from our datasets highlight that the impact of alcohol involvement on personality change may be limited to shorter intervals during specific developmental time-frames and that the relation between changes in personality and alcohol involvement may be best viewed from a noncausal perspective.     

Examining Visual-Verbal Associations in Children with and Without Reading Disorder

The purpose of this study was to investigate verbal working memory processing both before and after providing semantically elaborated training sentences designed to enhance memory for symbol-word (visual-verbal) pairs. Abilities of 20 children diagnosed with Reading Disorder (RD) and 20 age-matched peers who were normally achieving in reading (NA) were compared (M = 10 years old). Results demonstrated RD children experienced significantly more difficulties on measures of complex auditory-verbal working memory than their NA peers. The best predictor of reading performance was word recall ability measured after students were provided with semantic training sentences. Findings have important implications for identifying young children with potential reading impairment.     

The codevelopment of skill at and preference for use of retrieval-based processes for solving addition problems: individual and sex differences from first to sixth grades

The ability to retrieve basic arithmetic facts from long-term memory contributes to individual and perhaps sex differences in mathematics achievement. The current study tracked the codevelopment of preference for using retrieval over other strategies to solve single-digit addition problems, independent of accuracy, and skilled use of retrieval (i.e., accuracy and reaction time [RT]) from first to sixth grades inclusive (N=311). Accurate retrieval in first grade was related to working memory capacity and intelligence, and it predicted a preference for retrieval in second grade. In later grades, the relation between skill and preference changed such that preference in one grade predicted accuracy and RT in the next grade as RT and accuracy continued to predict future gains in preference. In comparison with girls, boys had a consistent preference for retrieval over other strategies and had faster retrieval speeds, but the sex difference in retrieval accuracy varied across grades. Results indicate that ability influences early skilled retrieval, but both practice and skill influence each other in a feedback loop later in development and provide insights into the source of the sex difference in problem-solving approaches.     

Psychologists' Experiences with the Better Access Initiative: A Pilot Study

The Australian Government's Better Access initiative was introduced in late 2006 to increase treatment rates for people with mental disorders. It provides for reimbursement of psychologists' services through Medicare. The current pilot study examines the experiences of psychologists with this initiative. A random sample of 204 of 4,235 psychologists in private practice was approached and 73 psychologists (36%) were interviewed. The current study suggests that psychologists have had positive experiences with Better Access. They have appreciated the greater security of income and greater variety of work afforded by the initiative, and they have observed flow‐on benefits in terms of increased access and reduced stigma for their clients. Additional research is required to corroborate these findings with a larger sample of psychologists, but the current findings provide indicative evidence that Better Access is assisting psychologists to meet a previously unmet community need for mental health care.     

Pathways Between Concealable Stigmatized Identities and Substance Misuse

Individuals with concealable stigmatized identities often possess no obviously devalued attributes, yet are at greater risk for problematic substance use compared to their privileged counterparts. We present a conceptual model, which proposes that identity‐relevant content and characteristics have important implications for cognitive, affective, and behavioral consequences of stigma‐related stress. In doing so, we synthesize stigma‐related models from the extant literature and attempt to integrate these concepts with previous work detailing potential contributors to substance use behaviors specifically. Finally, we ask readers to consider the various ways in which the content and characteristics of an individual's stigmatized identity might combine with situational and additional individual difference factors to influence the likelihood of substance misuse.     

Course of Antisocial Behavior during Emerging Adulthood: Developmental Differences in Personality

Despite similar normative changes in antisocial behavior (AB) and traits of disinhibition and negative emotionality during "emerging adulthood," few studies have tested if there are developmental differences in personality over this period for distinct courses of AB. In a college cohort assessed at ages 18 and 25, we examined if mean-level changes on traits from the Tridimensional Personality Questionnaire varied by course of AB. Compared to persisters, those who desisted in AB from 18 to 25 exhibited a larger decrease on novelty seeking and larger increase on reward dependence. A significant mean-level decline was observed for harm avoidance, but was unrelated to AB course. Findings support theories of the co-development of personality and AB during emerging adulthood.     

Influence of functional impairment and social support on depressive symptoms in persons with diabetes

Tested the buffering model of social support among 158 adults with diabetes. We predicted that, among patients with higher levels of illness-related impairment, adequate social support would act as a buffer against depression. Measures included the Beck Depression Inventory; the Sickness Impact Profile; and an assessment of the adequacy of social support to enable the patient to deal with illness-related tasks, domestic chores, financial responsibilities, and emotional needs. Depressive symptoms correlated positively with functional impairment (r = .58, p less than .001) and negatively with the adequacy of social support (r = -.31, p less than .001). In addition, social support moderated depression in the face of greater impairment such that, among patients who reported the most illness-related functional disabilities, adequate support provided a relative protection from depression. The findings suggest that individuals with inadequate support are most at risk to become depressed when disability related to illness increases.
