Building a multiple modality, theory-based physical activity intervention: The development of CardiACTION!

OBJECTIVES: Despite the widely acknowledged benefits of regular physical activity (PA), specific goals for increased population levels of PA, and strongly recommended strategies to promote PA, there is no evidence suggesting that the prevalence of PA is improving. If PA intervention research is to be improved, theory should be used as the basis for intervention development, participant context or environment should be considered in the process, and intervention characteristics that will heighten the likelihood of translation into practice should be implemented (e.g., ease of implementation, low human resource costs). The purpose of this paper is to describe the implementation of the aforementioned concepts within the intervention development process associated with CardiACTION an ongoing randomized 2 × 2 factorial trial. METHODS: The Ecological Model of Physical Activity integrated with Protection Motivation Theory was used to inform the design of the interventions. This integrated model was selected to allow for the development of theory-based individual, environmental, and individually + environmentally targeted physical activity interventions. All intervention strategies were matched to proposed mediators of behavior change. Strategies were then matched to the most appropriate interactive technology (i.e., interactive computer session, automated telephone counseling, and tailored mailings) delivery channel. CONCLUSIONS: The potential implications of this study include determining the independent and combined influence of individual and environment mechanisms of behavior change on intervention effectiveness. In addition, all intervention models are developed to be scalable and disseminable to a broad audience at a low cost.     

Organizational Justice: Personality Traits or Emotional Intelligence? An Empirical Study in an Italian Hospital Context

The purpose of this study was to investigate the role of personality traits and emotional intelligence in relation to organizational justice. The Organizational Justice Scale, the Eysenck Personality Questionnaire–Revised Short Form, and the Bar‐On Emotional Quotient Inventory were administered to 384 Italian nurses. The emotional intelligence dimensions explained a greater percentage of the incremental variance in relation to the four organizational justice dimensions (distributive: ΔR²= .11; procedural: ΔR²= .12; interpersonal: ΔR²= .19; informational: ΔR²= .16) with respect to personality traits (distributive: R²= .06; procedural: R²= .08; interpersonal: R²= .12; informational: R²= .09). The results highlight the role of emotional intelligence in explaining organizational justice, thereby offering new research and intervention perspectives.     

Role of the dorsal hippocampus in object memory load

The dorsal hippocampus is crucial for mammalian spatial memory, but its exact role in item memory is still hotly debated. Recent evidence in humans suggested that the hippocampus might be selectively involved in item short-term memory to deal with an increasing memory load. In this study, we sought to test this hypothesis. To this aim we developed a novel behavioral procedure to study object memory load in mice by progressively increasing the stimulus set size in the spontaneous object recognition task. Using this procedure, we demonstrated that naive mice have a memory span, which is the number of elements they can remember for a short-time interval, of about six objects. Then, we showed that excitotoxic selective lesions of the dorsal hippocampus did not impair novel object discrimination in the condition of low memory load. In contrast, the same lesion impaired novel object discrimination in the high memory load condition, and reduced the object memory span to four objects. These results have important heuristic and clinical implications because they open new perspective toward the understanding of the role of the hippocampus in item memory and in memory span deficits occurring in human pathologies, such as Alzheimer's disease and schizophrenia.     

Correlations between subjective well-being, dyadic adjustment and marital satisfaction in Brazilian married people

This study aimed to investigate the relationships between the constructs subjective well-being (SWB), dyadic adjustment (DA) and marital satisfaction (MS). Participants were 106 married Brazilians, of both sexes, with a mean age of 42 (+/- 11) years. Instruments used for the sociodemographic characterization and socioeconomic classification were the Subjective Wellbeing Scale (SWBS), the Dyadic Adjustment Scale (DAS) and the Marital Satisfaction Scale (MSS). Through the analysis of correlations and of stepwise multiple regression, it was verified that all the factors of the dyadic adjustment showed correlation with the marital satisfaction. The satisfaction with life (factor of the SWBS) and dyadic satisfaction (factor of the DAS), were positively and significantly correlated (r = .20: p = .04), which reveals that people who say they are satisfied with life in different domains also do so in relation to the marital experience,     

The stability of inhibited/uninhibited temperament from ages 3 to 11 years in mauritian children

Stability of inhibited/uninhibited temperament was assessed using 1,795 Mauritian children tested at ages 3, 8, and 11 years. Children were divided into uninhibited, middle, and inhibited groups at each age based on social behavior. Results indicated that, relative to uninhibited children (1) those inhibited at age 3 obtained larger inhibition scores at age 8 (p< .0001), (2) those inhibited at age 8 obtained larger inhibition scores at age 11 (p< .002), and (3) those remaining inhibited from ages 3 to 8 obtained larger inhibition scores at age 11 (p< .002). Relative to children who changed classification from ages 3 to 8, those remaining inhibited obtained larger inhibition scores (p< .05) and those remaining uninhibited obtained smaller inhibition scores (p< .015) at age 11. Inhibition scores tended to be higher in females by age 11. Results remained regardless of ethnicity. The results provide some support that inhibited/uninhibited temperament remains stable from ages 3 to 8 and may continue to age 11. The results suggest cross-cultural generalizability of these findings with implications regarding the development of anxiety disorders in the Mauritian population. The efforts of Cyril Dalais, Brian Bell, Athenea Chiriaca, and all the local members of the longitudinal study, the Mauritius Joint Child Health Project, are gratefully acknowledged. We are also especially thankful to Drs. Michael E. Dawson, David Walsh, and Bill McClure for their helpful comments and suggestions.The data used in this study were collected while the project was supported by the Medical Research Council (UK), the Wellcome Trust (UK), and the Mauritian government. The data were analyzed and findings written as part of the first author's dissertation work under the support of the NIMH Pre-doctoral Individual National Research Service Award and a USC Dissertation Fellowship Award.     

Screening for personality disorders in a nonclinical population

Based on the Inventory of Interpersonal Problems (IIP), the IIP-PD and the IIP-C screening scales were developed to distinguish personality disorder (PD) from non-PD and Cluster C from other PD, respectively, in a clinic population. Two studies were conducted to determine (a) validity and reliability of these IIP scales for PD screening in a nonclinical population, (b) specificity of IIP-C for identifying Cluster C, and (c) usefulness of the IIP scales for screening Cluster A. College students were screened using the IIP scales (Study 1, N = 454, Study 2, N = 87). High and low scorers completed PD-related questionnaires in Study 1 and a clinical interview for PD symptomatology in Study 2. Results indicated strong test-retest reliability, internal consistency, and factorial, convergent, and external validity. The scales tapped a common deficit in interpersonal relatedness, with some distinction between externalizing and internalizing dimensions, respectively, and both scales were positively and significantly associated with schizotypal traits. In conclusion, the IIP-PD and IIP-C are useful and valid screening instruments for identifying any versus no PD in nonclinical populations.     

Theory and Method of Social Representations

This paper gives an overview of social representation theory, definitions of the key terms and of the social processes leading to a representation and to social identity. Six empirical studies are presented and details of their methods and findings are given to illustrate this social psychological approach. These studies are about the ontogenesis of gender, the public sphere in Brazil, madness on British television, images of androgyny in Switzerland, individualism and democracy in post-communist Europe and metaphorical thinking about conception. The methods are ethnography, interviews, focus-groups, content analysis of media, statistical analysis of word associations, questionnaires and experiments. Finally, social representation theory is compared to theories of attitudes, schemata and social cognition.     

Technical variation in a sample of high level judo players

Technical actions performed by two groups of judokas who won medals at World Championships and Olympic Games during the period 1995-2001 were analyzed. In the Super Elite group (n = 17) were the best athletes in each weight category. The Elite group (n = 16) were medal winners who were not champions and did not win more than three medals. Super Elite judokas used a greater number of throwing techniques which resulted in scores, even when expressed relative to the total number of matches performed, and these techniques were applied in more directions than those of Elite judokas. Further, the number of different throwing techniques and the variability of directions in which techniques were applied were significantly correlated with number of wins and the number of points and ippon scored. Thus, a greater number of throwing techniques and use of directions for attack seem to be important in increasing unpredictability during judo matches.
