Alcohol use disorders and psychological distress: a prospective state-trait analysis

The present study examined the association between alcohol use disorders (AUDs) and psychological distress over an 11-year period using a sample of 378 young adults (46% men, 54% women: baseline age = 18.5; 51% with paternal history of alcoholism). The authors examined this relation using a state-trait model, which decomposes variance in a given construct into a general traitlike factor that spans measurement occasion and more situational, occasion-specific variability. Trait AUD and trait distress were correlated (r =.43), suggesting that the tendency to meet criteria for an AUD is associated with the tendency to experience psychological distress. Much of this association was due to 3rd variables (primarily neuroticism but also childhood stressors and behavioral undercontrol), supporting a common 3rd-variable influence model of comorbidity.     

The natural history of problem gambling from age 18 to 29

Aggregate-level prevalences and individual-level developmental trajectories of untreated problem gambling were examined in an 11-year, 4-wave longitudinal study spanning the adolescent through young adult years. The past-year prevalences, 3-4 year incidences, and lifetime prevalences of problem gambling from adolescence through young adulthood were relatively stable at 2%-3%, 1%-2%, and 3%-5%, respectively. Despite the stability of the prevalences at the aggregate level, problem gambling appeared to be more transitory and episodic than enduring and chronic at the individual level. The present study is consistent with the limited evidence available on the natural history of problem gambling in the community in suggesting that natural recovery may be the rule rather than the exception.     

Case study: Reinforcement control of severe aggression exhibited by a child with autism in a family home

This clinical case study describes in-home treatment of severe aggression and tantrum behavior exhibited by an 11 -year-old child with autism, using methods of differential reinforcement comparable to those of a case study by Luiselli (1990). No significant reductions in problem conduct occurred when a parent implemented differential reinforcement of other behavior (DRO) in conjunction with publicly posted ‘good behavior rules,’ physical management training, and redirection to relaxation. Control was established when the child was reinforced for compliance with task demands in conjunction with extinction, implemented directly by professional support staff working in the home. Despite demonstrable parental consistency, systematic training, and fading of supports, results were not maintained at follow-up. The generality of differential reinforcement as a practical intervention for severe aggression in family homes is questioned.     

Gender Traits and Self-Concept as Indicators of Problem Eating and Body Dissatisfaction Among Children

The present study was designed to examine the role of gender traits, body mass index (BMI), and self-concept in predicting levels of problem eating and body dissatisfaction among both girls and boys aged between 8 and 10 (85% were Anglo-Australian Caucasian, 15% were Caucasians from non-English backgrounds). Two hundred and two children completed questionnaires, which examined problem-eating attitudes and behaviors, body dissatisfaction, gender traits, and self-concept. Children's height and weight were measured to determine children's BMI. Gender traits predicted problem eating for boys but not for girls. Self-concept was found to predict problem eating for both boys and girls. BMI was also a predictor of problems for girls. The only predictor of body dissatisfaction for boys and girls was BMI. The findings are discussed in light of previous research, which has been conducted, on adolescents. Further studies are needed to understand more fully the development of problem eating and body dissatisfaction before the onset of puberty and adolescence.     

Conceptual clusters in figurative language production

Although most prior research on figurative language examines comprehension, several recent studies on the production of such language have proved to be informative. One of the most noticeable traits of figurative language production is that it is produced at a somewhat random rate with occasional bursts of highly figurative speech (e.g., Corts & Pollio, 1999). The present article seeks to extend these findings by observing production during speech that involves a very high base rate of figurative language, making statistically defined bursts difficult to detect. In an analysis of three Baptist sermons, burst-like clusters of figurative language were identified. Further study indicated that these clusters largely involve a central root metaphor that represents the topic under consideration. An interaction of the coherence, along with a conceptual understanding of a topic and the relative importance of the topic to the purpose of the speech, is offered as the most likely explanation for the clustering of figurative language in natural speech.     

TAS-20 alexithymia in obesity, and its links to personality

We studied the association between alexithymia (20-item Toronto Alexithymia Scale, TAS-20) and obesity, and also assessed the construct validity of the TAS-20 in terms of personality dimensions in obese patients. The TAS-20 and its subscales were analysed for their correlations with the NEO Personality Inventory - Revised (NEO PI-R) in an obese sample of 259 patients. Obesity was associated with higher scores on the TAS-20 than a Swedish reference sample. Obese men furthermore scored higher on Externally Oriented Thinking than the obese women. TAS-20 scores correlated with elevated Neuroticism and lower levels of Extraversion and Openness, in agreement with most previous research, but also somewhat unexpectedly with lower Conscientiousness and for women also with lower Agreeableness. The TAS-20 subscales showed divergent associations with personality variables, largely in accordance with previous findings. The associations were more prominent for the women, and some gender-specific patterns not previously reported were also revealed.
