Improving the Definition of Exercise Maintenance: Evaluation of Concepts Related to Adherence

Physical activity has been demonstrated in the literature as an effective way to reduce the risk for development of chronic disease. The Transtheoretical Model (TTM) of behavior change has been developed as a means to predict and facilitate movement into healthier lifestyle behaviors. The model is centered on "stages of change", which describe a continuum of readiness to engage in a health behavior change. Stages contain temporal, qualitative, and quantitative characteristics. This was a six-month study that evaluated the effectiveness of stage-matched (theorized to be pertaining only to the maintenance stage of change) vs. generic (theorized to be pertaining to anyone, regardless of stage) newsletters in assisting subjects to attain the Maintenance stage of change. It also sought to identify further qualitative characteristics that can differentiate between the Action and Maintenance stages of change. Results indicated that monthly stage-matched newsletters were no more effective in helping subjects reaching Maintenance than were the generic newsletters. Exerciser self-schema was related to stages of change, but those relationships differed from baseline to six-month follow-up, indicating development of exerciser self-schema during the study period. Implications of this are discussed. Other concepts discussed included "structure" of change process, in that three new scores were developed …

Organization of Narrative Discourse in Children and Adolescents with Acute Traumatic Brain Injury (open access)

Organization of Narrative Discourse in Children and Adolescents with Acute Traumatic Brain Injury

Children with a recent history of TBI often demonstrate impaired memory, which can be affected by impaired attention, processing speed or impaired verbal information processing. The purpose of this study was to determine if qualitative differences exist among the narrative recall of TBI patients that is not adequately accounted for by standard scoring methods. Sixty-six TBI subjects ranging in age from 6 to 16 were given the Wide Range and Memory and Learning (WRAML) Story Memory subtest and selected subtests from the Wechsler Intelligence Scale for Children - Third Edition (WISC-III). Mean elapsed time since injury was 53 days. Recall of the story on the WRAML subtest was hand-recorded by the examiner. A supplemental scoring method accounted for differences in length, errors, and disorganization. Comparisons were made to a randomly selected control group consisting of 16 hospitalized subjects between 7 and 15 years with no history of head injury, neurological condition or event. Findings suggest the WRAML Story Memory subtest is relatively robust in providing information regarding the quality of recall, with the exception of not accounting for the addition of erroneous details. Subjects with both cortical and subcortical injuries were more likely to add superfluous details to their stories. …

Use of the Beck Depression Inventory in Northern Brazil (open access)

Use of the Beck Depression Inventory in Northern Brazil

The Beck Depression Inventory (BDI) is a popular screening and research instrument for measuring severity of depression. The instrument was translated to Portuguese for use in Brazil in 1979; however, it was not until recently that its psychometric properties have been tested empirically for the Brazilian population. The purpose of the present study was to explore the BDI's psychometric properties in a northern region of Brazil and to test for possible relationships between certain demographic variables and BDI outcomes. Samples used in this study were from an urban area in Roraima, the northernmost state of Brazil. The BDI showed adequate levels of internal consistency in nonclinical and clinical samples. Female respondents had significantly higher scores than male respondents. Those who had lower levels of education, income, or occupational status had significantly higher scores than those with higher levels of these variables. Adolescents had significantly higher scores than adults from all age groups except those from age 19 to 22. No significant difference was found between those who identified themselves as “indigenous” and those who identified themselves as “non-indigenous.” Regression analysis results showed that the combination of gender, education, and age best accounted for the variance in BDI scores. An ANCOVA …

Identifying AD/HD subtypes using the cognitive assessment system and the NEPSY (open access)

Identifying AD/HD subtypes using the cognitive assessment system and the NEPSY

The purpose of this study was to examine the ability of the Cognitive Assessment System (CAS) and the NEPSY, A Developmental Neuropsychological Assessment, to differentiate between the subtypes of Attention Deficit/ Hyperactivity Disorder (AD/HD). The CAS and NEPSY are neuropsychological instruments which provide norms for AD/HD children in general. This study examined the performance of the two subtypes of AD/HD on the CAS and NEPSY. In addition, this study examined the performance of the two AD/HD groups on the Screening Test for Auditory Processing Disorders (SCAN). Since AD/HD children tend to have difficulty with language, the SCAN was used to determine if any of the AD/HD subjects had auditory processing difficulties that might impact their performance on the CAS and/or NEPSY subtests. The sample consisted of 118 children between the ages of 8 and 12 years of age. Using the DSM-IV criteria, the children were diagnosed as having three types of AD/HD: A Predominantly Hyperactive-Impulsive Type (AD/HD-HI), a Predominantly Inattentive Type (AD/HD-I) and a Combined Type The subtypes were also identified by the Attention Deficit Disorders Evaluation Scale-Home Version (ADDES-H). Only two subtypes, AD/HD-I and AD/HD-C, were identified by the ADDES-H. There were not enough AD/HD-HI subjects to include in …

Predictors of Use and Outcomes of Youth and Family Centers (open access)

Predictors of Use and Outcomes of Youth and Family Centers

This study analyzed data from Dallas Public Schools and Dallas Youth and Family Centers (YFCs) to explore variables associated with referrals to and utilization of Youth and Family Centers. Data from students enrolled in third, eighth or tenth grade during the 1996-1997, 1997-1998 and 1998-1999 school years were analyzed to determine the reasons for YFC referral and utilization, and to compare standardized test scores and attendance. Of the 6956 students in third, eighth and tenth grades initially referred to YFCs during those three school years, 5173 (74.3%) made at least one YFC visit. The 5173 students made an average of 2.69 visits and accessed an average of 1.18 services per year. Medical visits accounted for 42.5% of YFC visits, and mental health visits accounted for 46% of YFC visits. Results of logistic regression analyses indicate a significant difference for utilization upon referral and continued use of the YFC when the constant is compared to a set of predictor variables. For both analyses, the predictor variables were Chapter I status, LEP status, reason for referral, gender, special education status, ethnicity, distance from home school to referral YFC, food stamp eligibility and referral source. While outcome data regarding attendance and scores on …

A Confirmatory Factor Analysis of WRAML Scores in a Group of Academically Talented Students (open access)

A Confirmatory Factor Analysis of WRAML Scores in a Group of Academically Talented Students

The purpose of this study was to confirm the original factor structure of the Wide Range Assessment of Memory and Learning (WRAML) utilizing a non-clinical adolescent population. Additional analysis examined the relationship between SAT-M scores and spatial relations ability. Exploratory analyses were conducted to determine ethnic and gender differences on the WRAML and subtests from the DAT. Sixty-four academically talented adolescents completed the WRAML and the mechanical reasoning and spatial relations subtests from the Differential Aptitude Test (DAT). The confirmatory factor analysis found the data obtained to not be a good fit for the factor structure of the WRAML (Sheslow & Adams, 1990). Additional confirmatory analyses were conducted which examined data fit of a three factor model found by reanalyzing the standardization data (Burton et al., 1996; Wasserman & Cambias, 1991) as well as two null models. The data failed to fit any of these three models. No support was found for the second hypothesis that predicted a positive relationship between SAT-M scores and spatial relations ability. Ethnic and gender differences on the WRAML and two DAT subtests were examined and discussed. Limitations of this study were reviewed which may have accounted for the overall lack of results.

Behavior Patterns among Children with a History of Metopic Synostosis (open access)

Behavior Patterns among Children with a History of Metopic Synostosis

Metopic synostosis is a condition in which the metopic suture of the human cranium fuses prematurely and may be related to poor behavioral inhibition leading to behaviors commonly associated with Attention-Deficit Hyperactivity Disorder (ADHD). The purpose of this project was to examine the behavior patterns among children with a history of metopic synostosis. It was hypothesized that children with a history of metopic synostosis would exhibit many of the same behavioral patterns associated with ADHD. It was also hypothesized that children with a history of simple synostosis not involving the metopic suture would not evidence this type of behavioral pattern. In order to test these hypotheses, the behavior of three groups of children was compared including (1) children who had a history of metopic synostosis (M= 7.63 years, SD = 1.92 years), (2) children who had a history of simple craniosynostosis not involving the metopic suture (M= 7.54 years, SD = 1.88 years), and (3) a group of children diagnosed with ADHD (M=7.78 year, SD = 1.87 years). It was found using the Home and School versions of the Attention Deficit Disorders Evaluation Scale (ADDES) that children with a history of metopic synostosis demonstrate significantly more behavioral disturbances than children …
