An assessment of parent involvement in local interagency teams

The results of team members' evaluations of Local Interagency Teams in Vermont are used to assess the participation of parents in one level of the system of care. Active participation in discussions and knowledge of their child's legal rights were consistently highly rated aspects of parent participation. The rating of parents' appearing to feel that they were equal members was consistently low. Attendance at meetings and knowledge of services available showed significant growth over time.     

Oral contraceptive use among African American adolescents: Individual and community influences

Side effects of oral contraceptives are a noteworthy problem, particularly among low-income young women who reside in inner-city communities. The problem may be compounded by inadequate family planning services, particularly when such services are provided by general medical practices with high volumes of clients. This study examined the prevalence and correlates of pill-related side effects, with particular attention to the role of clinic characteristics. Participants were 177 pregnant and parenting African American adolescents and young women (average age=18.34). The experience of a pill-related side effect was the most frequently cited barrier to birth control use, and it was significantly related to contraceptive behavior. Finally, although participants attending comprehensive clinics experienced more barriers to medical service use than those attending neighborhood clinics, they reported fewer problems with pill-related side effects and better psychological functioning. Implications for future research and policy are discussed.

Sample Size Planning for Detecting Mediation Effects: A Power Analysis Procedure Considering Uncertainty in Effect Size Estimates

Abstract

When planning mediation studies, researchers are often interested in the sample size needed to achieve adequate power for testing mediation. Power depends on population effect sizes, which are unknown in practice. In conventional power analysis, effect size estimates, however, are often used as population values, which could result in underpowered studies. Uncertainty in effect size estimates has been considered in other sample size planning contexts (e.g., t-test, ANOVA), but has not been handled properly for planning mediation studies. In the current study, we proposed an easy-to-use sample size planning method for testing mediation with uncertainty in effect size estimates considered. We conducted simulation studies to demonstrate the impact of uncertainty in effect size estimates on power of testing mediation, and to provide sample size suggestions under different levels of uncertainty. Empirical examples were provided to illustrate the application of our method. R functions and a web application were developed to facilitate implementation.     

The very same thing: Extending the object token concept to incorporate causal constraints on individual identity

The contributions of feature recognition, object categorization, and recollection of episodic memories to the re-identification of a perceived object as the very same thing encountered in a previous perceptual episode are well understood in terms of both cognitive-behavioral phenomenology and neurofunctional implementation. Human beings do not, however, rely solely on features and context to re-identify individuals; in the presence of featural change and similarly-featured distractors, people routinely employ causal constraints to establish object identities. Based on available cognitive and neurofunctional data, the standard object-token based model of individual re-identification is extended to incorporate the construction of unobserved and hence fictive causal histories (FCHs) of observed objects by the pre-motor action planning system. It is suggested that functional deficits in the construction of FCHs are associated with clinical outcomes in both autism spectrum disorders and later-stage stage Alzheimer's disease.     

Myopic loss aversion: Demystifying the key factors influencing decision problem framing

Advancement of myopic loss aversion theory has been hamstrung by conflicting results, methodological inconsistencies, and a piecemeal approach toward understanding the key factors influencing decision problem framing. A series of controlled experiments provides a more holistic view of the variables promoting myopia. Extending the information horizon promotes broad framing, which propels risk. Evaluation frequency and decision frequency interact regardless of information horizon, supporting the notion that restricting either mechanism alleviates myopia. When conducting evaluations infrequently, neither segregating nor aggregating retrospective returns significantly alters risk preferences. Moreover, students and real retirement plan participants exhibit comparable appetites for risk, implying that both groups frame decision problems similarly. Explanations for these findings and avenues for future research are discussed.

Finding theory‐ and evidence‐based alternatives to fear appeals: Intervention Mapping

Fear arousal—vividly showing people the negative health consequences of life‐endangering behaviors—is popular as a method to raise awareness of risk behaviors and to change them into health‐promoting behaviors. However, most data suggest that, under conditions of low efficacy, the resulting reaction will be defensive. Instead of applying fear appeals, health promoters should identify effective alternatives to fear arousal by carefully developing theory‐ and evidence‐based programs. The Intervention Mapping (IM) protocol helps program planners to optimize chances for effectiveness. IM describes the intervention development process in six steps: (1) assessing the problem and community capacities, (2) specifying program objectives, (3) selecting theory‐based intervention methods and practical applications, (4) designing and organizing the program, (5) planning, adoption, and implementation, and (6) developing an evaluation plan. Authors who used IM indicated that it helped in bringing the development of interventions to a higher level.     

Anticipatory Planning of Sequential Hand and Finger Movements

ABSTRACT

Hand movements may be anticipatorily planned to reach an immediate target and at the same time facilitate movements to subsequent targets. Researchers have proposed that in anticipatory planning, information about subsequent targets needs to be processed to engage in the planning of the next movement. To test this hypothesis, the authors varied the information 48 participants had about to-be-executed two-step hand and finger movement sequences prior to a choice reaction signal. Movements were initialized faster if participants had advance information about the second target of the sequence than if participants had no advance information at all. The results imply that movement segments to late targets in a movement sequence may be at least partially planned, even if information about earlier targets is not yet available.     

Adoption of community-based cardiac rehabilitation programs and physical activity following phase III cardiac rehabilitation in Scotland: A prospective and predictive study

Little is known about levels of physical activity and attendance at phase IV community-based Cardiac Rehabilitation (CR) programs following completion of exercise-focussed, hospital-based phase III CR. This study aims to test, compare and combine the predictive utility of the Common-Sense Self-Regulation Model (CS-SRM) and the extended Theory of Planned Behaviour (TPB) with action planning for two rehabilitation behaviours: physical activity and phase IV CR attendance. Individuals diagnosed with coronary heart disease (n = 103) completed baseline measures of illness perceptions, intentions, perceived behavioural control (PBC), action planning and past physical activity in the last week of a phase III CR program, and 95 participants completed follow-up measures of physical activity and attended phase IV CR (objectively confirmed) 2 months later. Only one predictor (PBC/cyclical timeline) significantly predicted levels and change of physical activity. While illness perceptions were not predictive of phase IV CR attendance, the extended TPB model showed good predictive power with action planning and intention as the most powerful predictors. Amongst participants who planned when and where to attend phase IV CR at the end of phase III rehabilitation, 65.9% subsequently attended a phase IV CR program compared to only 18.5% of those who had not made a plan. This study adds to our understanding of cardiac rehabilitation behaviour after completion of health service delivered programs. Comparing theoretical models and rehabilitation behaviours contributes to the development of behaviour theory.     

Predicting retirement preparation through the design of a new measure

Researchers' capacity to investigate retirement planning behaviour is impeded by the lack of rigorous measurement within the literature. For this study, a comprehensive measure based on the reflexive planning domains of public protection, self‐insurance, and self‐protection was developed and evaluated in a sample of 174 employees aged ≥45 years. Variables of gender, age, income and core self‐evaluations were examined for their influence on planning effort in each of the three domains. Results indicated a clean, three‐factor structure for retirement planning behaviours. All variables emerged as predictors of planning effort in one or more domains. Implications of results for future research into retirement planning and the targeting of planning interventions are discussed.
