Challenges of Evaluating Multilevel Interventions

This article uses the Comprehensive Mixed-Methods Participatory Evaluation (CMMPE; Nastasi and Hitchcock Transforming school mental health services: Population-based approaches to promoting the competency and wellness of children, Thousand Oaks, CA: Corwin Press with National Association of School Psychologists 2008; Nastasi et al. School-based mental health services: creating comprehensive and culturally specific programs. Washington, DC: American Psychological Association 2004) model as a framework for addressing the multiplicity of evaluation decisions and complex nature of questions related to program success in multilevel interventions. CMMPE defines program success in terms of acceptability, integrity, social or cultural validity, outcomes (impact), sustainability and institutionalization, thus broadening the traditional notions of program outcomes. The authors use CMMPE and an example of a community-based multilevel sexual risk prevention program with multiple outcomes to discuss challenges of evaluating multilevel interventions. The sexual risk program exemplifies what Schensul and Tricket (this issue) characterize as multilevel intervention–multilevel evaluation (M–M), with both intervention and evaluation at community, health practitioner, and patient levels. The illustration provides the context for considering several challenges related to M–M designs: feasibility of randomized controlled trials within community-based multilevel intervention; acceptability and social or cultural validity of evaluation procedures; implementer, recipient, and contextual variations in program success; interactions among levels of the intervention; unanticipated changes or conditions; multiple indicators of program success; engaging multiple stakeholders in a participatory process; and evaluating sustainability and institutionalization. The complexity of multilevel intervention and evaluation designs challenges traditional notions of evaluation research and experimental designs. Overcoming these challenges is critical to effective translation of research to practice in psychology and related disciplines.     

Socio-Ecological Predictor Model of Parental Intention to Participate in Triple P-Positive Parenting Program

We examined variables associated with parental intention to participate in a parenting program viewed within a socio-ecological framework. In two metropolitan areas in Japan, 222 families voluntarily completed a series of questionnaires. A series of multiple regression analyses was used to evaluate the Socio-Ecological Predictor Model that was able to account for 50% of the variance associated with parental intention to participate in a parenting program. The most significant predictor in the model was program features, which accounted for 30% of the variance. It is important to consider program features that make it more likely that parents will engage positively in a parenting program. We discuss parental intention to participate in a parenting program as well as the limitations of the study and areas for future research.     

More Than Attendance: The Importance of After-School Program Quality

A central theme of the articles featured in this issue is the need to improve the quality of after-school programs. In this commentary, we discuss why student engagement, program characteristics and implementation, staff training, and citywide policy are key considerations in the effort to define and achieve high quality programs for youth.     

I see what you're saying: the integration of complex speech and scenes during language comprehension

The effect of language-driven eye movements in a visual scene with concurrent speech was examined using complex linguistic stimuli and complex scenes. The processing demands were manipulated using speech rate and the temporal distance between mentioned objects. This experiment differs from previous research by using complex photographic scenes, three-sentence utterances and mentioning four target objects. The main finding was that objects that are more slowly mentioned, more evenly placed and isolated in the speech stream are more likely to be fixated after having been mentioned and are fixated faster. Surprisingly, even objects mentioned in the most demanding conditions still show an effect of language-driven eye-movements. This supports research using concurrent speech and visual scenes, and shows that the behavior of matching visual and linguistic information is likely to generalize to language situations of high information load.     

Relating numeric cognition and language processing: Do numbers and words share a common representational platform?

Numerical processing and language processing are both grounded in space. In the present study we investigated whether these are fully independent phenomena, or whether they share a common basis. If number processing activates spatial dimensions that are also relevant for understanding words, then we can expect that processing numbers may influence subsequent lexical access to words. Specifically, if high numbers relate to upper space, then they can be expected to facilitate understanding of words such as bird that are having referents typically found in the upper vertical space. The opposite should hold for low numbers. These should facilitate the understanding of words such as ground referring to entities with referents in the lower vertical space. Indeed, in two experiments we found evidence for such an interaction between number and word processing. By eliminating a contribution of linguistic factors gained from additional investigations on large text corpora, this strongly suggests that understanding numbers and language is based on similar modal representations in the brain. The implications of these findings for a broader perspective on grounded cognition will be discussed.     

Teaching Beginning Braille Reading Using an Alphabet or Uncontracted Braille Approach

This study examined the effects of using a research based print reading program modified to accommodate beginning braille readers using an alphabet or uncontracted braille reading approach with five beginning braille readers. Four of the 5 participants displayed a clear increase in their ability to read high frequency words when they began using the Early Steps reading program modified to an Early Steps Alphabet Braille Reading Program. Study findings indicate that access to reading activities and materials afforded to sighted peers resulted in improved reading outcomes for children with visual impairments. Teachers, participants, and family members all viewed the use of the uncontracted braille reading program and materials favorably. Specialized reading instruction was also perceived as beneficial by teachers of students with visual impairments when the training addressed the specific needs of braille readers.     

EEG asymmetry and sleep mentation during REM and NREM

The hypothesis that dreaming is mediated by the right hemisphere was evaluated by monitoring EEG power asymmetry during REM and NREM sleep, and obtaining mentation reports when short-term temporal shifts in the EEG indicated relative left- or right-hemispheric dominance. Content analyses provided no support for the right-hemisphere hypothesis; indeed, some scales showed higher content during relative left-hemispheric dominance. In contrast to earlier reports, no difference between REM and NREM in EEG asymmetry was observed.     

Another look at the theoretical assumptions of adolescent egocentrism

We attempt in this paper to reevaluate the theoretical assumptions of D. Elkind's theory of adolescent egocentrism Child Development, 38, 1025–1034). We argue that the construct is not well placed in the ontogenetic context of Piagetian logical development, and that the theory cannot account for stage transition or the appearance of the imaginary audience (IA) and personal fable (PF) components. We argue that the IA and PF constructions are better understood as problems in interpersonal understanding. These components are reinterpreted in terms of stage sequence that describes the ontogenesis of interpersonal understanding. The advantages of this model are highlighted.     

Eye-fixation patterns during reading confirm theories of language comprehension

Eye-movement patterns during reading are consistent with proposition-by-proposition models of speech comprehension. (1) Fixation times are least affected by word length at ends of clauses: this confirms the theory based on the study of speech comprehension that, at such points, attention is directed inward to text integration. (2) Fixation time for words at the end of clauses is longer for canonical sequences which conform to the pattern, “N-V-N = actor-action-object”; this confirms the view that complete semantic integration of such sequences is routinely delayed until their completion. A two-variable model based on principles of exhaustive visual search and speech comprehension accounts for 80% of the fixation durations in a sample paragraph from Just and Carpenter (1980) and Thibodeou, Just ond Carpenter (1982). This comprehension-based model compares favorably with their models constructed within a production-system framework. This result clarifies the relationship between reading and listening.
