Structural and Community Change Outcomes of the Connect‐to‐Protect Coalitions: Trials and Triumphs Securing Adolescent Access to HIV Prevention,Testing, and Medical Care

Connect to Protect (C2P), a 10‐year community mobilization effort, pursued the dual aims of creating communities competent to address youth's HIV‐related risks and removing structural barriers to youth health. We used Community Coalition Action Theory (CCAT) to examine the perceived contributions and accomplishments of 14 C2P coalitions. We interviewed 318 key informants, including youth and community leaders, to identify the features of coalitions’ context and operation that facilitated and undermined their ability to achieve structural change and build communities’ capability to manage their local adolescent HIV epidemic effectively. We coded the interviews using an a priori coding scheme informed by CCAT and scholarship on AIDS‐competent communities. We found community mobilization efforts like C2P can contribute to addressing the structural factors that promote HIV‐risk among youth and to community development. We describe how coalition leadership, collaborative synergy, capacity building, and local community context influence coalitions’ ability to successfully implement HIV‐related structural change, demonstrating empirical support for many of CCAT's propositions. We discuss implications for how community mobilization efforts might succeed in laying the foundation for an AIDS‐competent community.     

Identification of the People and Critique of the Ideas in Meyer’s Philosophy of Occupation Therapy

This article identifies the people Meyer mentions in his article, “Philosophy of Occupation Therapy,” published in Archives of Occupational Therapy (Meyer, 1922c Meyer, A. (1922c). Philosophy of occupation therapy. Archives of Occupational Therapy, 1(1), 1–10. [Reprinted in American Journal of Occupational Therapy, 31(10), 639–642]. [Google Scholar]) and critiques the ideas discussed. Because there is no list of references provided within the article itself, the researcher selected the methodology of source criticism to identify the names of individuals appearing in the text—locating each person’s publications and analyzing the publications for influential ideas. Twenty-one names were found and publications were located for 15. Ideas were identified and analyzed. Finally, Meyer’s ideas were compared to current models of practice and a proposed reference list was created.     

On the relative contributions of noncontingent reinforcement and escape extinction in the treatment of food refusal

In the current investigation, we evaluated the relative effects of noncontingent reinforcement (NCR), escape extinction, and a combination of NCR and escape extinction as treatment for the feeding problems exhibited by 4 children. For each participant, consumption increased only when escape extinction was implemented, independent of whether NCR was present or absent. These results were consistent with prior research suggesting that positive reinforcement alone is insufficient for increasing consumption, and that escape extinction often is necessary to increase and maintain food acceptance. However, NCR appeared to decrease inappropriate behavior for some participants.     

Assessment of deviant arousal in adult male sex offenders with developmental disabilities

Ten individuals, residing in a treatment facility specializing in the rehabilitation of sex offenders with developmental disabilities, participated in an arousal assessment involving the use of the penile plethysmograph. The arousal assessments involved measuring change in penile circumference to various categories of stimuli both appropriate (adult men and women) and inappropriate (e.g., 8- to 9-year-old boys and girls). This approach extends the existing assessment literature by the use of repeated measurement and single-subject experimental design. Data from these assessments were analyzed to determine if clear and informative outcomes were obtained. Overall, three general patterns of results emerged. Some participants showed differentiated deviant arousal or higher levels of arousal to specific inappropriate stimuli (deviant is a term used in the existing sex-offender literature to describe this type of arousal). Other participants showed undifferentiated deviant arousal, in which case they showed nonspecific arousal to inappropriate stimuli. The remaining participants showed no arousal to inappropriate stimuli but did show arousal to appropriate stimuli. Implications for assessment, treatment, and future directions are discussed.     

Relationship between self-reported intensity of headache and magnitude of surface EMG

The study was designed to examine the relationship between self-reported intensity of headache and surface EMG. 98 patients, diagnosed by their neurologists with "muscle-contraction headaches" (tension-type headaches) were referred to evaluate their suitability for biofeedback therapy. At the time of examination, they were asked to rate their average headache intensity on a 10-point scale. Surface EMG data were collected to assess actual muscle contraction. Analysis indicated that among patients diagnosed with muscle contraction headache, there is a positive significant correlation between self-reported intensity of headache and actual muscle-contraction. The current data lend support to the hypothesis that the tension in the headaches currently described as "tension-type" may in fact refer to actual muscular tension or contraction.     

Rats' performance on variable-interval schedules with a linear feedback loop between response rate and reinforcement rate

Three experiments investigated whether rats are sensitive to the molar properties of a variable-interval (VI) schedule with a positive relation between response rate and reinforcement rate (i.e., a VI+ schedule). In Experiment 1, rats responded faster on a variable ratio (VR) schedule than on a VI+ schedule with an equivalent feedback function. Reinforced interresponse times (IRTs) were shorter on the VR as compared to the VI+ schedule. In Experiments 2 and 3, there was no systematic difference in response rates maintained by a VI+ schedule and a VI schedule yoked in terms of reinforcement rate. This was found both when the yoking procedure was between-subject (Experiment 2) and within-subject (Experiment 3). Mean reinforced IRTs were similar on both the VI+ and yoked VI schedules, but these values were more variable on the VI+ schedule. These results provided no evidence that rats are sensitive to the feedback function relating response rate to reinforcement rate on a VI+ schedule.     

Electrophysiological responses to errors and feedback in the process of action regulation

The anterior cingulate cortex (ACC) is believed to be involved in the executive control of actions, such as in monitoring conflicting response demands, detecting errors, and evaluating the emotional significance of events. In this study, participants performed a task in which evaluative feedback was delayed, so that it was irrelevant to immediate response control but retained its emotional value as a performance indicator. We found that a medial frontal feedback-related negativity similar to the error-related negativity (ERN) tracked affective response to the feedback and predicted subsequent performance. Source analysis of the feedback-related negativity and ERN revealed a common dorsomedial ACC source and a rostromedial ACC source specific to the ERN. The oscillatory nature of these sources provides further evidence that the ERN reflects ongoing theta activity generated in the mediofrontal regions. These results suggest that action regulation by the cingulate gyrus may require the entrainment of multiple structures of the Papez corticolimbic circuit.     

Potential Clinical Implications of Implicit and Explicit Attitudes Within Possible Exercise Selves Schemata: A Pilot Study

Our purpose was to explore implicit as well as explicit exercise schemata of 51 inactive to highly active college students. For the implicit measure, a pilot study was used to establish the word set (exercise-related, nonexercise-related, and nonwords) for the lexical decision task. A latency differential was calculated based on reaction times to these word sets. Participants used self-regulatory functions to rate both hoped and feared exercise selves and reported workout hours. An estimate of aerobic fitness was derived. Results showed that implicit exercise attitudes were related to the importance placed on being an exerciser and on avoiding being a nonexerciser. Those who self-identified as an exerciser had higher levels of self-efficacy, workouts, and fitness. In contrast, those who self-identified as a nonexerciser were less active and fit and seemed to dwell on negative thoughts related to self-efficacy. Clinicians might help clients explore these attitudes, especially importance.
